+# Smart contract interfaces
+
+## Technology
+
+CIC smart contracts are implemented using the *solidity* programming
+language for the (Ethereum Virtual Machine (EVM).
+
+## Adopted standards
+
+### Signing
+
+### ERC - Direct use
+
+The following well-known solidity interfaces are used directly.
+
+- [ERC20 - Token Standard](https://eips.ethereum.org/EIPS/eip-20)
+
+- [ERC165 - Standard Interface
+  Detection](https://eips.ethereum.org/EIPS/eip-165)
+
+- [ERC173 - Contract Ownership
+  Standard](https://eips.ethereum.org/EIPS/eip-173)
+
+- [ERC191 - Signed Data
+  Standard](https://eips.ethereum.org/EIPS/eip-191)

+The following well-known solidity interfaces are partially implemented
+in CIC native interfaces.
+
+- [ERC5679 - Token Minting and
+  Burning](https://eips.ethereum.org/EIPS/eip-5679) (See `Minter`,
+  `Burner`)
+
+## Native interfaces
+
+### 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.
+        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.

+
+        // 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);

+
+### Burner
+
+Attached to `ERC20` and `ERC721` tokens that may be *burned*.
+
+Implements the `burn(...)` part of `ERC5679` for interoperability.
+
+ERC165 Interface identifier  
+bc4babdd
+
+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 _burn) external returns (bool);
+
+        // Burn all tokens held by signer.
+        function burn() external returns (bool);
+
+        // 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);

+        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 );
+

+        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 );

+        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 or 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.

+
+        // 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

+
+### 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).
+

+### 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.

+
+### 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`)

+
+### TokenVend
+
+This interface defines the mechanism for which a specific ERC20 token
+may be exchanged for a different ERC20 token.
+
+A typical use-case is generation of voting tokens based on a momentary
+voucher balance. This is especially useful if the original ERC20 token
+is subject to decay (demurrage).
+
+The tokens used for exchange **SHOULD** be locked for the full duration
+of holding the vended tokens.
+
+The withdrawal function may or may not allow partial withdrawals.

+### 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.

+### 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.
