                            Preamble
-The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
+  The GNU General Public License is a free, copyleft license for
 software and other kinds of works.
-The licenses for most software and other practical works are designed to take away your freedom to share and change the works.  By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
+  The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
 the GNU General Public License is intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
 software for all its users.  We, the Free Software Foundation, use the
 GNU General Public License for most of our software; it applies also to
 any other work released this way by its authors.  You can apply it to
 your programs, too.
-When we speak of free software, we are referring to freedom, not price.  Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
+  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
-Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
+  To protect your rights, we need to prevent others from denying you
 these rights or asking you to surrender the rights.  Therefore, you have
 certain responsibilities if you distribute copies of the software, or if
 you modify it: responsibilities to respect the freedom of others.
-A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate.  Many developers of free software are heartened and encouraged by the resulting cooperation.  However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
+  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must pass on to the recipients the same
 freedoms that you received.  You must make sure that they, too, receive
 or can get the source code.  And you must show them these terms so they
 know their rights.
-The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community.  It requires the operator of a network server to provide the source code of the modified version running there to the users of that server.  Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
+  Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify it.
-An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals.  This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
+  For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software.  For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.
-The precise terms and conditions for copying, distribution and modification follow.
+  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.
  The precise terms and conditions for copying, distribution and
 modification follow.

 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
-An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License.  If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

  1. Source Code.
 The "source code" for a work means the preferred form of the work for making modifications to it.  "Object code" means any non-source form of a work.
-A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
+  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
-The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form.  A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
+  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
-The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities.  However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work.  For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those

  2. Basic Permissions.
 All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met.  This License explicitly affirms your unlimited permission to run the unmodified Program.  The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work.  This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
-You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force.  You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright.  Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.

  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
-When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.

 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
 You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
-You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
+  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
 You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
-    a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
+  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
-    b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7.  This requirement modifies the requirement in section 4 to "keep intact all notices".
+    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
-    c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy.  This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged.  This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
+    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
-    d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
+    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
-A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit.  Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
+    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
 You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
-    a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
+  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
-    b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
+    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
-    c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source.  This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
+    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
-    d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge.  You need not require recipients to copy the Corresponding Source along with the object code.  If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source.  Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
+    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
-    e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
+    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
-A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
+    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
-A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling.  In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage.  For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product.  A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
+  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
-"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source.  The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
+  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
-If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information.  But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
+  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
-The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed.  Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
+  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
-Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
+  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
 "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law.  If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.

 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.

 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
-Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.

  9. Acceptance Not Required for Having Copies.
-You are not required to accept this License in order to receive or run a copy of the Program.  Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance.  However, nothing other than this License grants you permission to propagate or modify any covered work.  These actions infringe copyright if you do not accept this License.

 ## Native interfaces
 ### ACL
 A simple Access Control List definition that returns true of false
 depending on whether an signatory (address) is allowed to operate in a
 given context.
 #### ERC165 Interface identifier
 3ef25013
 #### Solidity interface definition
    interface IACL {
        // Returns true if the address has permission to operate in the given context.
        function have(address _address) external view returns(bool);
    }
 #### Example implementation
 <git://holbrook.no/eth-accounts-index.git>
 ### Accounts Index
 Append-only list of addresses. Typically used for access control lists.
 Addresses may be *added*, *removed*, aswell as *deactivated* and
 *activated*. Deactivated accounts still count towards the `entryCount`.
 The `entry` method is used to iterate the account list. The order of
 which accounts are returned is not guaranteed. Any returned value
 matching `address(0x00)` should be skipped, and not counted towards
 `entryCount`.
 May optionally record time when account was added.
 #### ERC165 Interface identifier
 b7bca625
 #### Solidity interface definition
    interface IAccountsIndex {
        // Address added to store, index in array.
        event AddressAdded(uint256 indexed _idx, address _account);
        // Return number of entries in index.
        function entryCount() external view returns (uint256);
        // Return entry at the spceificed index.
        // Will revert if index is beyond array length.
        // An entry result of 0 means the entry should be skipped, and not count towards entry count.
        function entry(uint256) external view returns (address);
        // Add an entry to the index. Incresases the entry count.
        function add(address) external returns (bool);
        // Verify that the entry exists in the index.
        // Implements ACL
        function have(address) external view returns (bool);
        // Retrieve the timestamp when account was added.
        // If time is not being tracked, a value of 0 should be returned.
        function time(address) external view returns (uint256);
    }
 #### Reference implementation
 <git://holbrook.no/eth-accounts-index.git> (v0.5.1)
 ### Accounts Index Mutable
 Extends the functionality of `Accounts Index` to allow changes to the
 address list.
 Addresses may be *added*, *removed*, aswell as *deactivated* and
 *activated*. Deactivated accounts still count towards the `entryCount`.
 #### ERC165 Interface identifier
 9479f0ae
 #### Solidity interface definition
    interface IAccountsIndexMutable {
        // Active status of address changed, and by whom changed.
        event AddressActive(address indexed _account, bool _active);
        // Address removed from store, and by whom removed.
        event AddressRemoved(address _account);
        // Remove an entry from the index. Reduces the entry count.
        function remove(address) external returns (bool);
        // Deactivate account but keep in index. Does not affect entry count.
        function deactivate(address) external returns (bool);
        // Activate previously deactivated account. Does not affect entry count.
        function activate(address) external returns (bool);
        // Check if account exists and is active;
        function isActive(address) external view returns (bool);
    }
 #### Reference implementation
 <git://holbrook.no/eth-accounts-index.git> (v0.5.1)
 ### Burner
 Attached to `ERC20` and `ERC721` tokens that may be *burned*.
 Implements the `burn(...)` part of `ERC5679` for interoperability.
 #### ERC165 Interface identifier
 b1110c1b
 #### Solidity interface definition
    interface IBurner {
        // Token(s) successfully burned; by who and how much.
        event Burn(address indexed _burner, uint256 _burned);
        // Satisfies ERC 5679
        function burn(address _from, uint256 _amount, bytes calldata _data) external;
        // Burn given amount of tokens held by signer.
        function burn(uint256 _amount) external returns (bool);
        // Burn all tokens held by signer.
        // Returns the amount of tokens burned.
        function burn() external returns (uint256);
        // Total amount of tokens that have been burned.
        function totalBurned() external returns (uint256);
        // Total amount of tokens ever minted.
        // If totalSupply() is available (ERC20, ERC721 Enumerable), this equals totalSupply() + totalBurned().
        function totalMinted() external returns (uint256);
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Chrono
 Define a creation time for a resource.
 Complements `ERC5007`.
 #### ERC165 Interface identifier
 4db1ccd4
 #### Solidity interface definition
    interface IChrono {
        // Returns the timestamp of when a resource corresponding to _idx was first created.
        // int64 chosen as return value for simpler interoperability with ERC5007.
        function createTime(uint256 _idx) external returns(int64);
    }
 #### Example implementation
 <https://git.defalsify.org/eth-erc721> (BadgeToken contract)
 ### Declarator
 Permissionless store of signed claims made by an address about other
 addresses, or addresses about themselves.
 It is used to declare or respond to certifications of vouchers, NFT,
 voucher members.
 Addresses may be Externally Owned Accounts or smart contracts.
 Claims may be made with or without topics. A missing topic is synonymous
 with a topic value of `bytes32(0x00)`.
 Any number of claims can be made about an address under any number of
 topics. All claims must be stored, and returned in the order which they
 were added.
 #### ERC165 Interface identifier
 21b7493b
 #### Solidity interface definition
    interface IDeclarator {
        event DeclarationAdded(address indexed _declarator, address indexed _subject, bytes32 indexed _topic, bytes32 _proof);
        // Get all declarations for a subject (without topic) signed by a declarator
        function declaration(address _declarator, address _subject) external view returns ( bytes32[] memory );
        // Get all declarations for a subject for the given topic signed by a declarator
        function declaration(address _declarator, address _subject, bytes32 _topic) external view returns ( bytes32[] memory );
        // Get number of declarations the declarator has ever signed
        function declarationCount(address _declarator) external view returns ( uint256 );
        // Get the subject of a declarator's declarations at the specific index
        function declarationAddressAt(address _declarator, uint256 _idx) external view returns ( address );
        // Add a declaration for the subject
        function addDeclaration(address _subject, bytes32 _proof) external returns ( bool );
        // Add a declaration with topic for the subject
        function addDeclaration(address _subject, bytes32 _proof, bytes32 _topic) external returns ( bool );
        // Get the declarator that signed a declaration at the specificed index for a subject
        function declaratorAddressAt(address _subject, uint256 _idx) external view returns ( address );
        // Get the number of declarators that have signed for a subject
        function declaratorCount(address _subject) external view returns ( uint256 );
    }
 #### Reference implementation
 <git://holbrook.no/eth-address-index.git>
 ### Digest
 Allows encoding of digests according to a specific encoding scheme.
 Primary use-case is the abstraction of self-describing
 [Multhash](https://multiformats.io/multihash/) encoding.
 A default encoding *must* always be defined, and the encoding of a valid
 digest *must* succeed with the default encoding.
 #### ERC165 Interface identifier
 982ab05d
 #### Solidity interface definition
    interface IDigest {
        // Returns the default digest encoding used by the contract instance.
        function defaultDigestEncoding() external view returns (uint256 _encoding);
        // Check if the given encoding has been implemented in the contract instance.
        function haveDigestEncoding(uint256 _codec) external view returns(bool);
        // Verify and encode the given digest for a specific hashing algorithm.
        // Returns a zero-length byte array if digest is invalid.
        // Must succeed if called with the defaultDigestEncoding and a valid digest.
        function encodeDigest(bytes memory _data, uint256 _encoding) external view returns (bytes memory);
        // Encodes the digest using the default digest encoding.
        // Returns a zero-length byte array if digest is invalid.
        // Must succeed with a valid digest.
        function encodeDigest(bytes memory _data) external view returns (bytes memory);
    }
 #### Example implementation
 <git://holbrook.no/eth-event-msg.git>
 ### Expire
 Defines an expiry time after which token balances and supply *cannot
 change*.
 A contract defining an expiry *must not* allow changing the expiration
 time to a time in the past.
 #### ERC165 Interface identifier
 841a0e94
 #### Solidity interface definition
    interface IExpire {
        // Contract has expired.
        event Expired(uint256 _timestamp);
        // Expiry time has changed.
        event ExpiryChange(uint256 indexed _oldTimestamp, uint256 _newTimestamp);
        // The current expiration timestamp.
        function expires() external returns (uint256);
        // Check expiry and apply expiration if expired.
        // Return values must be:
        // 0: not yet expired.
        // 1: already expired.
        // >1: expiry executed.
        function applyExpiry() external returns(uint8);
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Faucet
 Used for dispensing tokens to any address.
 It can be used for gas tokens and *ERC20* alike.
 The interface is the same whether the faucet is dispensing from existing
 balance or minting new tokens.
 The value dispersed *must* be the same for all addresses.
 In general, four criteria are expected to exist in any combination for
 limiting access to the faucet:
 Time  
 A recipient may only use the faucet again after some time has passed.
 Balance threshold  
 A recipient may only use the faucet after its balance is below a certain
 amount.
 Membership  
 A recipient may only use the faucet if it has been added to an access
 control list.
 Capacity  
 The contract has sufficient token funds to dispense the current defined
 amount to dispense.
 The *check(address)* contract call *must* evaluate all four criteria,
 and *must* return `false` if any of the criteria are not met.
 #### ERC165 Interface identifier
 1a3ac634
 #### Solidity interface definition
    interface IFaucet {
        // Tokens were given to an address
        event Give(address indexed _recipient, address indexed _token, uint256 _value);
        // The amount that the faucet disperses has changed
        event FaucetAmountChange(uint256 _value);
        // Address of token the faucet represents
        // The faucet will return gas tokens with the zero-address is returned.
        function token() external returns (address);
        // Amount of tokens the faucet gives out
        function tokenAmount() external returns (uint256);
        // Give tokens to the given recipient. Returns amount of tokens given.
        function giveTo(address _recipient) external returns (uint256);
        // Give tokens to yourself. Returns amount of tokens given.
        function gimme() external returns (uint256);
        // Check if faucet may be used in the current contract state by _recipient
        function check(address _recipient) external view returns (bool);
        // Returns timestamp when faucet may be used again by _recipient
        // If 0 is returned, the address has not yet been used.
        // A return value of max(uint256) indicates that the faucet may not be used again.
        function nextTime(address _recipient) external returns (uint256);
        // Returns the token balance under which faucet may be used again by _recipient
        // A return value of max(uint256) indicates that the faucet may be used regardless
        //   of the token balance of _recipient
        function nextBalance(address _recipient) external returns (uint256);
    }

 ### Locator
 This interface supports `ERC721 Metadata`, in particular the
 `tokenURI(uint256)` call.
 Off-chain resources in the CIC network *must* be defined in terms of
 content addressed strings.
 It *must* be possible to refer to all off-chain resources directly by
 the content address.
 Furthermore, it *should* be possible to refer to a resource by a
 fully-qualified location on the web or an overlay network (e.g. tor).
 #### ERC165 Interface identifier
 ed75b333
 #### Solidity interface definition
    interface ILocator {
        // URI that may or may not point to a specific resource location.
        function toURI(bytes memory _data) external view returns (string memory);
        // URL pointing to a specific resource location.
        function toURL(bytes memory _data) external view returns(string memory);
    }
 #### Example implementation
 <git://holbrook.no/eth-event-msg.git>
 #### Expressing locators in terms of numeric token id
 Given the numeric token id `1234567890987654321` (`0x112210f4b16c1cb1`
 hex), and a base url `https://contentgateway.grassecon.net`, the result
 of the methods may be as follows:
 `toURI(toHex(1234567890987654321))`  
 -\>
 `https://contentgateway.grassecon.net/000000000000000000000000000000000000000000000000112210f4b16c1cb1`

 #### Expressing locators in terms of a digest
 Given the data `foo`, the digest algorithm `sha256` and a base url
 `https://contentgateway.grassecon.net`, the result of the methods may be
 as follows:
 `toURI(sha256(foo))`  
 -\>
 `"sha256:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"`

 #### Locator without URL
 Given the data `foo`, the digest algorithm `sha256` and no base url, the
 result of the methods may be as follows:
 `toURI(sha256(foo))`  
 -\>
 `"sha256:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"`

 ### Minter
 Attached to `ERC20` and `ERC721` tokens that may be minted.
 Implements the `mint(...)` and `safeMint(...)` parts of `ERC5679` for
 interoperability.
 #### ERC165 Interface identifier
 5878bcf4
 #### Solidity interface definition
    interface IMinter {
        // Tokens are successfully minted; by who, to whom and how much
        event Mint(address indexed _minter, address indexed _beneficiary, uint256 value);
        // The given token has been successfully minted; by who, to whom and how much
        event Mint(address indexed _minter, address indexed _beneficiary, address indexed _token, uint256 value);
        // Mint the specified value of tokens to the specified recipient
        function mintTo(address _beneficiary, uint256 value) external returns (bool);
        // Satisfies ERC5679 for ERC20
        function mint(address _beneficiary, uint256 value, bytes calldata _data) external;
        // Satisfies ERC5679 for ERC721
        function safeMint(address _beneficiary, uint256 value, bytes calldata _data) external;
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Msg
 Enables a reference "message" to describe the contract using an
 off-chain resource.
 The reference may or may not be mutable.
 The interface complements `Locator` and `MultiHash` to generate locators
 for how to resolve the reference.
 #### ERC165 Interface identifier
 a3002595
 #### Solidity interface definition
    interface IMsg {
        // Emitted when a new message digest has been set
        // Should not be emitted if the digest set is identical to the previous
        event Msg(bytes _msgDigest);
        // Get the current message content hash
        function getMsg() external view returns(bytes memory);
    }
 #### Example implementation
 <git://holbrook.no/eth-event-msg.git>
 ### Registry
 The Registry interface is a key-value store resolving well-known
 contract identifier names to contract addresses.
 It currently has two distinct uses in the CIC context:
 1.  Entry-point to discover all relevant contracts of CIC networks.
 2.  Unique (ERC20) token symbol resolver.
 #### ERC165 Interface identifier
 effbf671
 #### Solidity interface definition
    interface IRegistryClient {
        // Address added to store with the given key
        event AddressKey(bytes32 indexed _key, address _address);
        // Return the address of the contract identified by the given byte string
        function addressOf(bytes32) external view returns (address);
        // Indexed accessor for the full list of registred identifiers
        function identifier(uint256) external view returns (bytes32);
        // Number of registered interfaces
        function identifierCount() external view returns (uint256);
    }
 #### Contract registry implementation
 <git://holbrook.no/eth-contract-registry.git>
 #### Token index implementation
 <git://holbrook.no/eth-contract-registry.git>
 ### Seal
 Some smart contract parameters may need to be mutable over part of a
 smart contract’s lifetime.
 This interface provides a method to explicitly signal when certain
 parameters have been rendered immutable.
 The value of `sealState()` *must not* decrease, and must not exceed
 `maxSealState`.
 `maxSealState` is used to define that *all mutable parameters* have been
 rendered immutable. The practical implications of this will vary between
 contracts.
 The implementer is encouraged to use simple, descriptive names in the
 source code to describe the applicable seal states.
 Use cases of sealing include:
 - Whether more tokens can be minted
 - Allow ownership of a contract to be transferred
 - The expiry time of a token (see `Expire`)
 #### ERC165 Interface identifier
 0d7491f8
 #### Solidity interface definition
    interface ISeal {
        // Seal state has changed.
        event SealStateChange(bool indexed _final, uint256 _sealState);
        // The current seal state.
        function sealState() external view returns(uint256);
        // The numeric seal state in everything sealable has been sealed.
        function maxSealState() external view returns(uint256);
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Throttle
 An backend contract to limit access to a resource by time.
 The smart contract managing the resource calls `have(address)` on this
 contract to check if it can be made use of at the current point in time.
 This also implements [ACL](#acl).
 When the resource is made use of, it calls `poke(address)` method to
 register when it has been made use of.
 The `next(address)` method returns the timestamp from which the resource
 may be used again by the given address. The implementer is permitted to
 change the value at any time.
 #### ERC165 Interface identifier
 242824a9
 #### Solidity interface definition
    interface IThrottle {
        // Returns true if the given address is authorized to make use of the resource at the current moment.
        // Implements ACL
        function have(address _address) external view returns(bool);
        // Returns the timestamp when the resource may next be used by the given address.
        // A return value of 0 or a timestamp before the current timestamp indicates that the resource may used momentarily.
        // A return value of max uint265 can be used to indicate that the resource may never be used again by the address.
        function next(address _address) external returns(bool);
        // Must be called when the resource is being used.
        function poke(address _address) external returns(bool);
    }
 #### Reference implementation
 <git://holbrook.no/eth-faucet.git> (PeriodSimple contract)
 ### TokenLimit
 Define limits of value amounts of tokens that individual addresses can
 hold.
 Limits are inclusive; a limit for 42 means transfer resulting in a token
 balance *higher* than 42 should be rejected.
 A return value of 0 indicates that the token is categorically not
 accepted by the holder.
 #### ERC165 Interface identifier
 23778613
 #### Solidity interface definition
    interface ITokenLimit {
        // Returns limit of total value a holder will accept of a specific token.
        // The value limit returned is inclusive; A limit of 42 means any operation resulting in a balance OVER 42 should be rejected.
        // A value of 0 means that no value of the token is accepted.
        function limitOf(address _token, address _holder) external view returns(uint256);
    }
 #### Reference implementations
 - <git://holbrook.no/erc20-limiter.git>
 ### TokenQuote
 Quote an output token value for a given value of input tokens.
 Both input and output value is denominated in the smallest available
 unit of respective tokens.
 #### ERC165 Interface identifier
 dbb21d40
 #### Solidity interface definition
    interface ITokenQuote {
        // Returns, within a current context, what value of outTokens the given value of inTokens translates to.
        // The values are given in smallest unit of each respective token.
        function valueFor(address _outToken, address _inToken, uint256 value) external view returns (uint256);
    }
 #### Example implementation
 - <git://holbrook.no/erc20-limiter.git>
 ### TokenRateChange
 Enables detection of properties for CIC tokens that change value over
 time, e.g. through demurrage.
 It allows defining the granularity of the rate of change, aswell as a
 frequency for which the rate of change is applied.
 A method for canonical value change calculations is also provided.
 #### ERC165 Interface identifier
 b716af03
 #### Solidity interface definition
    interface ITokenChangeRate {
        // Time unit resolution for rate of change.
        // A value of 0 indicates no rate of change,
        function changeTimeUnit() external view returns(uint256);
        // Rate of change per changeTimeUnit(), signed integer.
        // An effective value of 0 indicates no rate of change.
        function changeRate() external view returns (int256);
        // Number of decimals with which the changeRate is defined.
            // changeRate() should be divided by 10 ** changeRateDecimals() to obtain effective value
        function changeRateDecimals() external view returns(uint8);
        // Timestamp from when rate of change should be applied.
        // A value of 0 indicates no rate of change,
        function changeStartTime() external view returns(uint256);

 ### TokenSwap
 Token swap interface that can fit token escrow purposes aswell as token
 swap contracts.
 Optionally may define a `defaultToken`, that may among other things be
 used for `withdraw()` calls without an `inToken`.
 An explicit *ERC20 approval* of the balance to be transacted will
 usually be required for the implementing contract.
 If the value 0 is passed as argument to `deposit` or `withdraw`,
 implementers can choose one of two possible outcomes:
 - Noop. 0 *must* be returned.
 - Use *balance* or the max available *allowance*. The actual (spent)
  value *must* be returned.
 #### ERC165 Interface identifier
 4146b765
 #### Solidity interface definition
    interface ITokenSwap {
        // Emitted when a new deposit has been made.
        event Deposit(address indexed _token, uint256 _value);
        // Default token used to access the token swap.
        // Returns zero-address if no default token is defined.
        function defaultToken() external returns (address);
        // Add inToken liquidity to the tune of given value. 
        // Requires token approval for the corresponding value.
        // If value is 0, up to the full approval MAY be used for the transfer.
        function deposit(address _inToken, uint256 _value) external returns (uint256);
        // Withdraw pending outToken balance of given value in the pool for the sender.
        // May require token approval for defaultToken if used by contract as exchange for the withdrawal.
        // If value is 0, up to the full approval value MAY be used for the transfer.
        function withdraw(address _outToken, uint256 _value) external returns (uint256);
        // Exchange inToken equalling given value for outToken.
        // Requires token approval for the value of inToken.
        // If value is 0, up to the full approval value MAY be used for the transfer.
        function withdraw(address _outToken, address _inToken, uint256 _value) external returns (uint256);
    }
 #### Reference implementations
 - <git://holbrook.no/erc20-pool.git>
 #### Handling deposits
 The implementation is free to decide whether deposits can be recovered
 directly, or if they will be locked in the smart contract - temporarily
 or permanently.
 For the duration deposits are locked, they are part of the smart
 contract’s swap liquidity. During this time, locked deposits may only be
 withdrawn in exchange for other tokens accepted by the contract.
 Deposits that are not locked should be withdrawable using the
 `withdraw(address,uint256)` (`0xf3fef3a3`) method signature.
 Of course, as with most swap contracts, the tokens available for
 withdrawal by the holder may not necessarily match the tokens that were
 deposited by the holder.
 ### TokenVote
 Execute elections with granular ERC20 token votes.
 A proposal submitted for vote may or may not contain multiple options.
 If multiple options are available, an ERC20 token holder may distribute
 its vote among the options with the granularity of the token balance.
 Voted tokens **SHOULD** be locked until the voting has finalized.
 Finalization of voting should be callable by anyone.

 #### Reference implementations

 ### Writer
 A complement to ERC173, which allows definition of a class of
 super-users for a contract.
 A super-user address may perform *more* actions than a "normal" address,
 aswell as *some* actions normally limited to the *contract owner*.
 If an *contract owner* is defined, No super-user should be able to
 perform actions that *contract owner* cannot perform.
 Typically, only the *contract owner*, if it is defined, can add or
 remove a super-user.
 Some use-case examples of super-user actions include:
 - Mint new tokens.
 - Change the amount dispensed by the faucet.
 - Edit access control lists.
 #### ERC165 Interface identifier

        // A writer has been added by _executor
        event WriterAdded(address _writer);

        event WriterDeleted(address _writer);
        // Add a new writer to the contract.
        function addWriter(address _writer) external returns (bool);
        // Remove existing writer from the contract.
        function deleteWriter(address _writer) external returns (bool);

@subsection Seal

 This interface provides a method to explicitly signal when certain parameters have been rendered immutable.
 The value of @code{sealState()} @emph{must not} decrease, and must not exceed @code{maxSealState}.
@code{maxSealState} is used to define that @emph{all mutable parameters} have been rendered immutable. The practical implications of this will vary between contracts.
 The implementer is encouraged to use simple, descriptive names in the source code to describe the applicable seal states.
 Use cases of sealing include:
@itemize
@item
 Whether more tokens can be minted
@item
 Allow ownership of a contract to be transferred
@item
 The expiry time of a token (see @code{Expire})

@subsection Throttle
 An backend contract to limit access to a resource by time.
 The smart contract managing the resource calls @code{have(address)} on this contract to check if it can be made use of at the current point in time. This also implements @ref{acl, ACL}.
 When the resource is made use of, it calls @code{poke(address)} method to register when it has been made use of.
 The @code{next(address)} method returns the timestamp from which the resource may be used again by the given address. The implementer is permitted to change the value at any time.

 Optionally may define a @code{defaultToken}, that may among other things be used for @code{withdraw()} calls without an @code{inToken}.
 An explicit @emph{ERC20 approval} of the balance to be transacted will usually be required for the implementing contract.
 If the value 0 is passed as argument to @code{deposit} or @code{withdraw}, implementers can choose one of two possible outcomes:

@subsubsection Handling deposits
 The implementation is free to decide whether deposits can be recovered directly, or if they will be locked in the smart contract - temporarily or permanently.
 For the duration deposits are locked, they are part of the smart contract's swap liquidity. During this time, locked deposits may only be withdrawn in exchange for other tokens accepted by the contract.
 Deposits that are not locked should be withdrawable using the @code{withdraw(address,uint256)} (@code{0xf3fef3a3}) method signature.
 Of course, as with most swap contracts, the tokens available for withdrawal by the holder may not necessarily match the tokens that were deposited by the holder.

 This interface defines the mechanism for which a specific ERC20 token may be exchanged for a different ERC20 token.

 The tokens used for exchange @strong{SHOULD} be locked for the full duration of holding the vended tokens.

 Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
                            Preamble
 The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
 The licenses for most software and other practical works are designed to take away your freedom to share and change the works.  By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
 When we speak of free software, we are referring to freedom, not price.  Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
 Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
 A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate.  Many developers of free software are heartened and encouraged by the resulting cooperation.  However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
 The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community.  It requires the operator of a network server to provide the source code of the modified version running there to the users of that server.  Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
 An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals.  This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
 The precise terms and conditions for copying, distribution and modification follow.
                       TERMS AND CONDITIONS
 0. Definitions.
 "This License" refers to version 3 of the GNU Affero General Public License.
 "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
 "The Program" refers to any copyrightable work licensed under this License.  Each licensee is addressed as "you".  "Licensees" and "recipients" may be individuals or organizations.
 To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy.  The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
 A "covered work" means either the unmodified Program or a work based on the Program.
 To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy.  Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
 To "convey" a work means any kind of propagation that enables other parties to make or receive copies.  Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
 An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License.  If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
 1. Source Code.
 The "source code" for a work means the preferred form of the work for making modifications to it.  "Object code" means any non-source form of a work.
 A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
 The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form.  A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
 The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities.  However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work.  For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
 The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
 The Corresponding Source for a work in source code form is that same work.
 2. Basic Permissions.
 All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met.  This License explicitly affirms your unlimited permission to run the unmodified Program.  The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work.  This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
 You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force.  You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright.  Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
 Conveying under any other circumstances is permitted solely under the conditions stated below.  Sublicensing is not allowed; section 10 makes it unnecessary.
 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
 When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
 4. Conveying Verbatim Copies.
 You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
 You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
 5. Conveying Modified Source Versions.
 You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7.  This requirement modifies the requirement in section 4 to "keep intact all notices".
    c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy.  This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged.  This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
 A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit.  Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
 6. Conveying Non-Source Forms.
 You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
    a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source.  This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
    d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge.  You need not require recipients to copy the Corresponding Source along with the object code.  If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source.  Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
 A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
 A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling.  In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage.  For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product.  A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
 "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source.  The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
 If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information.  But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
 The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed.  Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
 Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
 7. Additional Terms.
 "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law.  If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
 When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it.  (Additional permissions may be written to require their own removal in certain cases when you modify the work.)  You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
 Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
    e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
 All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10.  If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term.  If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
 If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
 Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
 8. Termination.
 You may not propagate or modify a covered work except as expressly provided under this License.  Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
 However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
 Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
 Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License.  If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
 9. Acceptance Not Required for Having Copies.
 You are not required to accept this License in order to receive or run a copy of the Program.  Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance.  However, nothing other than this License grants you permission to propagate or modify any covered work.  These actions infringe copyright if you do not accept this License.  Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
 10. Automatic Licensing of Downstream Recipients.
 Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License.  You are not responsible for enforcing compliance by third parties with this License.
 An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations.  If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
 You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License.  For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
 11. Patents.
 A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based.  The work thus licensed is called the contributor's "contributor version".
 A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version.  For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
 Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
 In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement).  To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
 If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
 If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
 A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License.  You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
 Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
 12. No Surrender of Others' Freedom.
 If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License.  If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
 13. Remote Network Interaction; Use with the GNU General Public License.
 Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software.  This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
 Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work.  The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
 14. Revised Versions of this License.
 The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time.  Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
 Each version is given a distinguishing version number.  If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation.  If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
 If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
 Later license versions may give you additional or different permissions.  However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
 15. Disclaimer of Warranty.
 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 16. Limitation of Liability.
 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 17. Interpretation of Sections 15 and 16.
 If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
 END OF TERMS AND CONDITIONS
            How to Apply These Terms to Your New Programs
 If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
 To do so, attach the following notices to the program.  It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
     <one line to give the program's name and a brief idea of what it does.>
     Copyright (C) <year>  <name of author>
     This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
     This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU Affero General Public License for more details.
     You should have received a copy of the GNU Affero General Public License along with this program.  If not, see <http://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
 If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source.  For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code.  There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
 You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.

  Burning](https://eips.ethereum.org/EIPS/eip-5679) (See `Minter`,
  `Burner`)
 ## Native interfaces
 ### ACL
 A simple Access Control List definition that returns true of false
 depending on whether an signatory (address) is allowed to operate in a
 given context.
 #### ERC165 Interface identifier
 3ef25013
 #### Solidity interface definition
    interface IACL {
        // Returns true if the address has permission to operate in the given context.
        function have(address _address) external view returns(bool);
    }
 #### Example implementation
 <git://holbrook.no/eth-accounts-index.git>
 ### Accounts Index
 Append-only list of addresses. Typically used for access control lists.
 Addresses may be *added*, *removed*, aswell as *deactivated* and
 *activated*. Deactivated accounts still count towards the `entryCount`.
 The `entry` method is used to iterate the account list. The order of
 which accounts are returned is not guaranteed. Any returned value
 matching `address(0x00)` should be skipped, and not counted towards
 `entryCount`.
 May optionally record time when account was added.
 #### ERC165 Interface identifier
 b7bca625
 #### Solidity interface definition
    interface IAccountsIndex {
        // Address added to store, index in array.
        event AddressAdded(uint256 indexed _idx, address _account);
        // Return number of entries in index.
        function entryCount() external view returns (uint256);
        // Return entry at the spceificed index.
        // Will revert if index is beyond array length.
        // An entry result of 0 means the entry should be skipped, and not count towards entry count.
        function entry(uint256) external view returns (address);
        // Add an entry to the index. Incresases the entry count.
        function add(address) external returns (bool);
        // Verify that the entry exists in the index.
        // Implements ACL
        function have(address) external view returns (bool);
        // Retrieve the timestamp when account was added.
        // If time is not being tracked, a value of 0 should be returned.
        function time(address) external view returns (uint256);
    }
 #### Reference implementation
 <git://holbrook.no/eth-accounts-index.git> (v0.5.1)
 ### Accounts Index Mutable
 Extends the functionality of `Accounts Index` to allow changes to the
 address list.
 Addresses may be *added*, *removed*, aswell as *deactivated* and
 *activated*. Deactivated accounts still count towards the `entryCount`.
 #### ERC165 Interface identifier
 9479f0ae
 #### Solidity interface definition
    interface IAccountsIndexMutable {
        // Active status of address changed, and by whom changed.
        event AddressActive(address indexed _account, bool _active);
        // Address removed from store, and by whom removed.
        event AddressRemoved(address _account);
        // Remove an entry from the index. Reduces the entry count.
        function remove(address) external returns (bool);
        // Deactivate account but keep in index. Does not affect entry count.
        function deactivate(address) external returns (bool);
        // Activate previously deactivated account. Does not affect entry count.
        function activate(address) external returns (bool);
        // Check if account exists and is active;
        function isActive(address) external view returns (bool);
    }
 #### Reference implementation

 ### Burner
 Attached to `ERC20` and `ERC721` tokens that may be *burned*.
 Implements the `burn(...)` part of `ERC5679` for interoperability.
 #### ERC165 Interface identifier
 b1110c1b
 #### Solidity interface definition
    interface IBurner {
        // Token(s) successfully burned; by who and how much.
        event Burn(address indexed _burner, uint256 _burned);
        // Satisfies ERC 5679
        function burn(address _from, uint256 _amount, bytes calldata _data) external;
        // Burn given amount of tokens held by signer.
        function burn(uint256 _amount) external returns (bool);
        // Burn all tokens held by signer.
        // Returns the amount of tokens burned.
        function burn() external returns (uint256);
        // Total amount of tokens that have been burned.
        function totalBurned() external returns (uint256);
        // Total amount of tokens ever minted.
        // If totalSupply() is available (ERC20, ERC721 Enumerable), this equals totalSupply() + totalBurned().
        function totalMinted() external returns (uint256);
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Chrono
 Define a creation time for a resource.
 Complements `ERC5007`.
 #### ERC165 Interface identifier
 4db1ccd4
 #### Solidity interface definition
    interface IChrono {
        // Returns the timestamp of when a resource corresponding to _idx was first created.
        // int64 chosen as return value for simpler interoperability with ERC5007.
        function createTime(uint256 _idx) external returns(int64);
    }
 #### Example implementation
 <https://git.defalsify.org/eth-erc721> (BadgeToken contract)
 ### Declarator
 Permissionless store of signed claims made by an address about other
 addresses, or addresses about themselves.
 It is used to declare or respond to certifications of vouchers, NFT,
 voucher members.
 Addresses may be Externally Owned Accounts or smart contracts.
 Claims may be made with or without topics. A missing topic is synonymous
 with a topic value of `bytes32(0x00)`.
 Any number of claims can be made about an address under any number of
 topics. All claims must be stored, and returned in the order which they
 were added.
 #### ERC165 Interface identifier
 21b7493b
 #### Solidity interface definition
    interface IDeclarator {
        event DeclarationAdded(address indexed _declarator, address indexed _subject, bytes32 indexed _topic, bytes32 _proof);
        // Get all declarations for a subject (without topic) signed by a declarator
        function declaration(address _declarator, address _subject) external view returns ( bytes32[] memory );
        // Get all declarations for a subject for the given topic signed by a declarator
        function declaration(address _declarator, address _subject, bytes32 _topic) external view returns ( bytes32[] memory );
        // Get number of declarations the declarator has ever signed
        function declarationCount(address _declarator) external view returns ( uint256 );
        // Get the subject of a declarator's declarations at the specific index
        function declarationAddressAt(address _declarator, uint256 _idx) external view returns ( address );
        // Add a declaration for the subject
        function addDeclaration(address _subject, bytes32 _proof) external returns ( bool );
        // Add a declaration with topic for the subject
        function addDeclaration(address _subject, bytes32 _proof, bytes32 _topic) external returns ( bool );
        // Get the declarator that signed a declaration at the specificed index for a subject
        function declaratorAddressAt(address _subject, uint256 _idx) external view returns ( address );
        // Get the number of declarators that have signed for a subject
        function declaratorCount(address _subject) external view returns ( uint256 );
    }
 #### Reference implementation
 <git://holbrook.no/eth-address-index.git>
 ### Digest
 Allows encoding of digests according to a specific encoding scheme.
 Primary use-case is the abstraction of self-describing
 [Multhash](https://multiformats.io/multihash/) encoding.
 A default encoding *must* always be defined, and the encoding of a valid
 digest *must* succeed with the default encoding.
 #### ERC165 Interface identifier
 982ab05d
 #### Solidity interface definition
    interface IDigest {
        // Returns the default digest encoding used by the contract instance.
        function defaultDigestEncoding() external view returns (uint256 _encoding);
        // Check if the given encoding has been implemented in the contract instance.
        function haveDigestEncoding(uint256 _codec) external view returns(bool);
        // Verify and encode the given digest for a specific hashing algorithm.
        // Returns a zero-length byte array if digest is invalid.
        // Must succeed if called with the defaultDigestEncoding and a valid digest.
        function encodeDigest(bytes memory _data, uint256 _encoding) external view returns (bytes memory);
        // Encodes the digest using the default digest encoding.
        // Returns a zero-length byte array if digest is invalid.
        // Must succeed with a valid digest.
        function encodeDigest(bytes memory _data) external view returns (bytes memory);
    }
 #### Example implementation
 <git://holbrook.no/eth-event-msg.git>
 ### Expire
 Defines an expiry time after which token balances and supply *cannot
 change*.
 A contract defining an expiry *must not* allow changing the expiration
 time to a time in the past.
 #### ERC165 Interface identifier
 841a0e94
 #### Solidity interface definition
    interface IExpire {
        // Contract has expired.
        event Expired(uint256 _timestamp);
        // Expiry time has changed.
        event ExpiryChange(uint256 indexed _oldTimestamp, uint256 _newTimestamp);
        // The current expiration timestamp.
        function expires() external returns (uint256);
        // Check expiry and apply expiration if expired.
        // Return values must be:
        // 0: not yet expired.
        // 1: already expired.
        // >1: expiry executed.
        function applyExpiry() external returns(uint8);
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Faucet
 Used for dispensing tokens to any address.
 It can be used for gas tokens and *ERC20* alike.
 The interface is the same whether the faucet is dispensing from existing
 balance or minting new tokens.
 The value dispersed *must* be the same for all addresses.
 In general, four criteria are expected to exist in any combination for
 limiting access to the faucet:
 Time  
 A recipient may only use the faucet again after some time has passed.
 Balance threshold  
 A recipient may only use the faucet after its balance is below a certain
 amount.
 Membership  
 A recipient may only use the faucet if it has been added to an access
 control list.
 Capacity  
 The contract has sufficient token funds to dispense the current defined
 amount to dispense.
 The *check(address)* contract call *must* evaluate all four criteria,
 and *must* return `false` if any of the criteria are not met.
 #### ERC165 Interface identifier
 1a3ac634
 #### Solidity interface definition
    interface IFaucet {
        // Tokens were given to an address
        event Give(address indexed _recipient, address indexed _token, uint256 _value);
        // The amount that the faucet disperses has changed
        event FaucetAmountChange(uint256 _value);
        // Address of token the faucet represents
        // The faucet will return gas tokens with the zero-address is returned.
        function token() external returns (address);
        // Amount of tokens the faucet gives out
        function tokenAmount() external returns (uint256);
        // Give tokens to the given recipient. Returns amount of tokens given.
        function giveTo(address _recipient) external returns (uint256);
        // Give tokens to yourself. Returns amount of tokens given.
        function gimme() external returns (uint256);
        // Check if faucet may be used in the current contract state by _recipient
        function check(address _recipient) external view returns (bool);
        // Returns timestamp when faucet may be used again by _recipient
        // If 0 is returned, the address has not yet been used.
        // A return value of max(uint256) indicates that the faucet may not be used again.
        function nextTime(address _recipient) external returns (uint256);
        // Returns the token balance under which faucet may be used again by _recipient
        // A return value of max(uint256) indicates that the faucet may be used regardless
        //   of the token balance of _recipient
        function nextBalance(address _recipient) external returns (uint256);
    }

 ### Locator
 This interface supports `ERC721 Metadata`, in particular the
 `tokenURI(uint256)` call.
 Off-chain resources in the CIC network *must* be defined in terms of
 content addressed strings.
 It *must* be possible to refer to all off-chain resources directly by
 the content address.
 Furthermore, it *should* be possible to refer to a resource by a
 fully-qualified location on the web or an overlay network (e.g. tor).
 #### ERC165 Interface identifier
 ed75b333
 #### Solidity interface definition
    interface ILocator {
        // URI that may or may not point to a specific resource location.
        function toURI(bytes memory _data) external view returns (string memory);
        // URL pointing to a specific resource location.
        function toURL(bytes memory _data) external view returns(string memory);
    }
 #### Example implementation
 <git://holbrook.no/eth-event-msg.git>
 #### Expressing locators in terms of numeric token id
 Given the numeric token id `1234567890987654321` (`0x112210f4b16c1cb1`
 hex), and a base url `https://contentgateway.grassecon.net`, the result
 of the methods may be as follows:
 `toURI(toHex(1234567890987654321))`  
 -\>
 `https://contentgateway.grassecon.net/000000000000000000000000000000000000000000000000112210f4b16c1cb1`

 #### Expressing locators in terms of a digest
 Given the data `foo`, the digest algorithm `sha256` and a base url
 `https://contentgateway.grassecon.net`, the result of the methods may be
 as follows:
 `toURI(sha256(foo))`  
 -\>
 `"sha256:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"`

 #### Locator without URL
 Given the data `foo`, the digest algorithm `sha256` and no base url, the
 result of the methods may be as follows:
 `toURI(sha256(foo))`  
 -\>
 `"sha256:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"`

 ### Minter
 Attached to `ERC20` and `ERC721` tokens that may be minted.
 Implements the `mint(...)` and `safeMint(...)` parts of `ERC5679` for
 interoperability.
 #### ERC165 Interface identifier
 5878bcf4
 #### Solidity interface definition
    interface IMinter {
        // Tokens are successfully minted; by who, to whom and how much
        event Mint(address indexed _minter, address indexed _beneficiary, uint256 value);
        // The given token has been successfully minted; by who, to whom and how much
        event Mint(address indexed _minter, address indexed _beneficiary, address indexed _token, uint256 value);
        // Mint the specified value of tokens to the specified recipient
        function mintTo(address _beneficiary, uint256 value) external returns (bool);
        // Satisfies ERC5679 for ERC20
        function mint(address _beneficiary, uint256 value, bytes calldata _data) external;
        // Satisfies ERC5679 for ERC721
        function safeMint(address _beneficiary, uint256 value, bytes calldata _data) external;
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Msg
 Enables a reference "message" to describe the contract using an
 off-chain resource.
 The reference may or may not be mutable.
 The interface complements `Locator` and `MultiHash` to generate locators
 for how to resolve the reference.
 #### ERC165 Interface identifier
 a3002595
 #### Solidity interface definition
    interface IMsg {
        // Emitted when a new message digest has been set
        // Should not be emitted if the digest set is identical to the previous
        event Msg(bytes _msgDigest);
        // Get the current message content hash
        function getMsg() external view returns(bytes memory);
    }
 #### Example implementation
 <git://holbrook.no/eth-event-msg.git>
 ### Registry
 The Registry interface is a key-value store resolving well-known
 contract identifier names to contract addresses.
 It currently has two distinct uses in the CIC context:
 1.  Entry-point to discover all relevant contracts of CIC networks.
 2.  Unique (ERC20) token symbol resolver.
 #### ERC165 Interface identifier
 effbf671
 #### Solidity interface definition
    interface IRegistryClient {
        // Address added to store with the given key
        event AddressKey(bytes32 indexed _key, address _address);
        // Return the address of the contract identified by the given byte string
        function addressOf(bytes32) external view returns (address);
        // Indexed accessor for the full list of registred identifiers
        function identifier(uint256) external view returns (bytes32);
        // Number of registered interfaces
        function identifierCount() external view returns (uint256);
    }
 #### Contract registry implementation
 <git://holbrook.no/eth-contract-registry.git>
 #### Token index implementation
 <git://holbrook.no/eth-contract-registry.git>
 ### Seal
 Some smart contract parameters may need to be mutable over part of a
 smart contract’s lifetime.
 This interface provides a method to explicitly signal when certain
 parameters have been rendered immutable.
 The value of `sealState()` *must not* decrease, and must not exceed
 `maxSealState`.
 `maxSealState` is used to define that *all mutable parameters* have been
 rendered immutable. The practical implications of this will vary between
 contracts.
 The implementer is encouraged to use simple, descriptive names in the
 source code to describe the applicable seal states.
 Use cases of sealing include:
 - Whether more tokens can be minted
 - Allow ownership of a contract to be transferred
 - The expiry time of a token (see `Expire`)
 #### ERC165 Interface identifier
 0d7491f8
 #### Solidity interface definition
    interface ISeal {
        // Seal state has changed.
        event SealStateChange(bool indexed _final, uint256 _sealState);
        // The current seal state.
        function sealState() external view returns(uint256);
        // The numeric seal state in everything sealable has been sealed.
        function maxSealState() external view returns(uint256);
    }
 #### Example implementation
 <https://git.grassecon.net/cicnet/erc20-demurrage-token.git>
 ### Throttle
 An backend contract to limit access to a resource by time.
 The smart contract managing the resource calls `have(address)` on this
 contract to check if it can be made use of at the current point in time.
 This also implements [ACL](#acl).
 When the resource is made use of, it calls `poke(address)` method to
 register when it has been made use of.
 The `next(address)` method returns the timestamp from which the resource
 may be used again by the given address. The implementer is permitted to
 change the value at any time.
 #### ERC165 Interface identifier
 242824a9
 #### Solidity interface definition
    interface IThrottle {
        // Returns true if the given address is authorized to make use of the resource at the current moment.
        // Implements ACL
        function have(address _address) external view returns(bool);
        // Returns the timestamp when the resource may next be used by the given address.
        // A return value of 0 or a timestamp before the current timestamp indicates that the resource may used momentarily.
        // A return value of max uint265 can be used to indicate that the resource may never be used again by the address.
        function next(address _address) external returns(bool);
        // Must be called when the resource is being used.
        function poke(address _address) external returns(bool);
    }
 #### Reference implementation
 <git://holbrook.no/eth-faucet.git> (PeriodSimple contract)
 ### TokenLimit
 Define limits of value amounts of tokens that individual addresses can
 hold.
 Limits are inclusive; a limit for 42 means transfer resulting in a token
 balance *higher* than 42 should be rejected.
 A return value of 0 indicates that the token is categorically not
 accepted by the holder.
 #### ERC165 Interface identifier
 23778613
 #### Solidity interface definition
    interface ITokenLimit {
        // Returns limit of total value a holder will accept of a specific token.
        // The value limit returned is inclusive; A limit of 42 means any operation resulting in a balance OVER 42 should be rejected.
        // A value of 0 means that no value of the token is accepted.
        function limitOf(address _token, address _holder) external view returns(uint256);
    }
 #### Reference implementations
 - <git://holbrook.no/erc20-limiter.git>
 ### TokenQuote
 Quote an output token value for a given value of input tokens.
 Both input and output value is denominated in the smallest available
 unit of respective tokens.
 #### ERC165 Interface identifier
 dbb21d40
 #### Solidity interface definition
    interface ITokenQuote {
        // Returns, within a current context, what value of outTokens the given value of inTokens translates to.
        // The values are given in smallest unit of each respective token.
        function valueFor(address _outToken, address _inToken, uint256 value) external view returns (uint256);
    }
 #### Example implementation
 - <git://holbrook.no/erc20-limiter.git>
 ### TokenRateChange
 Enables detection of properties for CIC tokens that change value over
 time, e.g. through demurrage.
 It allows defining the granularity of the rate of change, aswell as a
 frequency for which the rate of change is applied.
 A method for canonical value change calculations is also provided.
 #### ERC165 Interface identifier
 b716af03
 #### Solidity interface definition
    interface ITokenChangeRate {
        // Time unit resolution for rate of change.
        // A value of 0 indicates no rate of change,
        function changeTimeUnit() external view returns(uint256);
        // Rate of change per changeTimeUnit(), signed integer.
        // An effective value of 0 indicates no rate of change.
        function changeRate() external view returns (int256);
        // Number of decimals with which the changeRate is defined.
            // changeRate() should be divided by 10 ** changeRateDecimals() to obtain effective value
        function changeRateDecimals() external view returns(uint8);
        // Timestamp from when rate of change should be applied.
        // A value of 0 indicates no rate of change,
        function changeStartTime() external view returns(uint256);
        // Calculate value with change rate applied for given amount of time units.
        // Will calculate compounded change over the given amount of time units
        function applyChange(int256 _value, uint256 _changeTimeUnits) external view returns(int256);
    }
 #### Reference implementations
 - <git://holbrook.no/erc20-demurrage-token.git>
 ### TokenSwap
 Token swap interface that can fit token escrow purposes aswell as token
 swap contracts.
 Optionally may define a `defaultToken`, that may among other things be
 used for `withdraw()` calls without an `inToken`.
 An explicit *ERC20 approval* of the balance to be transacted will
 usually be required for the implementing contract.
 If the value 0 is passed as argument to `deposit` or `withdraw`,
 implementers can choose one of two possible outcomes:
 - Noop. 0 *must* be returned.
 - Use *balance* or the max available *allowance*. The actual (spent)
  value *must* be returned.
 #### ERC165 Interface identifier
 4146b765
 #### Solidity interface definition
    interface ITokenSwap {
        // Emitted when a new deposit has been made.
        event Deposit(address indexed _token, uint256 _value);
        // Default token used to access the token swap.
        // Returns zero-address if no default token is defined.
        function defaultToken() external returns (address);
        // Add inToken liquidity to the tune of given value. 
        // Requires token approval for the corresponding value.
        // If value is 0, up to the full approval MAY be used for the transfer.
        function deposit(address _inToken, uint256 _value) external returns (uint256);
        // Withdraw pending outToken balance of given value in the pool for the sender.
        // May require token approval for defaultToken if used by contract as exchange for the withdrawal.
        // If value is 0, up to the full approval value MAY be used for the transfer.
        function withdraw(address _outToken, uint256 _value) external returns (uint256);
        // Exchange inToken equalling given value for outToken.
        // Requires token approval for the value of inToken.
        // If value is 0, up to the full approval value MAY be used for the transfer.
        function withdraw(address _outToken, address _inToken, uint256 _value) external returns (uint256);
    }
 #### Reference implementations
 - <git://holbrook.no/erc20-pool.git>
 #### Handling deposits
 The implementation is free to decide whether deposits can be recovered
 directly, or if they will be locked in the smart contract - temporarily
 or permanently.
 For the duration deposits are locked, they are part of the smart
 contract’s swap liquidity. During this time, locked deposits may only be
 withdrawn in exchange for other tokens accepted by the contract.
 Deposits that are not locked should be withdrawable using the
 `withdraw(address,uint256)` (`0xf3fef3a3`) method signature.
 Of course, as with most swap contracts, the tokens available for
 withdrawal by the holder may not necessarily match the tokens that were
 deposited by the holder.
 ### TokenVote
 Execute elections with granular ERC20 token votes.
 A proposal submitted for vote may or may not contain multiple options.
 If multiple options are available, an ERC20 token holder may distribute
 its vote among the options with the granularity of the token balance.
 Voted tokens **SHOULD** be locked until the voting has finalized.
 Finalization of voting should be callable by anyone.
 #### ERC165 Interface identifier
 f2e0bfeb
 #### Solidity interface definition
    interface ITokenVote {
        // A new proposal has been created.
        event ProposalAdded(uint256 indexed _blockDeadline, uint256 indexed voteTargetPpm, uint256 indexed _proposalIdx);
        // A proposal vote has been completed.
        // The proposal is identified by the serial number in _proposalIdx. It is up to the implementer to define how the proposal should be retrieved by index.
        // The proposal result may be in one of three states:
        // * Ratified (_cancelled == false, _insufficient == false)
        // * Cancelled (_cancelled == true, _insufficient == false)
        // * Not reached quorum (_cancelled == false, _insufficient == true)
        event ProposalCompleted(uint256 indexed _proposalIdx, bool indexed _cancelled, bool indexed _insufficient, uint256 _totalVote);
        // Propose a new vote.
        // Voting is active until one of:
        // * total cancel vote reach quorum (_targetVotePpm, ppm = parts-per-million).
        // * _blockWait blocks from now.
        function propose(bytes32 _description, uint256 _blockWait, uint24 _targetVotePpm) external returns (uint256);

 ### Writer
 A complement to ERC173, which allows definition of a class of
 super-users for a contract.
 A super-user address may perform *more* actions than a "normal" address,
 aswell as *some* actions normally limited to the *contract owner*.
 If an *contract owner* is defined, No super-user should be able to
 perform actions that *contract owner* cannot perform.
 Typically, only the *contract owner*, if it is defined, can add or
 remove a super-user.
 Some use-case examples of super-user actions include:
 - Mint new tokens.
 - Change the amount dispensed by the faucet.
 - Edit access control lists.
 #### ERC165 Interface identifier
 abe1f1f5
 #### Solidity interface definition
    interface IWriter {
        // A writer has been added by _executor
        event WriterAdded(address _writer);
        // A writer has been removed by _executor
        event WriterDeleted(address _writer);
        // Add a new writer to the contract.
        function addWriter(address _writer) external returns (bool);
        // Remove existing writer from the contract.
        function deleteWriter(address _writer) external returns (bool);
        // Check whether the given address is a writer.
        function isWriter(address _writer) external view returns (bool);
    }
