 ## About Parity

 Parity's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity using the sophisticated and
 cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs.

-Parity comes with a built-in wallet. To access [Parity Wallet](http://127.0.0.1:8080/) simply go to http://127.0.0.1:8080/. It

- create and manage your Ethereum accounts;
- manage your Ether and any Ethereum tokens;
- create and register your own tokens;
- and much more.

+Parity also runs a server for running decentralized apps, or "Dapps", on `http://127.0.0.1:8080`.
+This includes a few useful Dapps, including Ethereum Wallet, Maker OTC, and a node status page.
+In a near-future release, it will be easy to install Dapps and use them through this web interface.

-
-# How to create new builtin Dapp.
-1. Clone this repository.
-
-   ```bash
-   $ git clone https://github.com/ethcore/parity.git
-   ```
-
-1. Create a new directory for your Dapp. (`./myapp`)
-
-   ```bash
-   $ mkdir -p ./parity/dapps/myapp/src/web
-   ```
-
-1. Copy your frontend files to `./dapps/myapp/src/web` (bundled ones)
-
-   ```bash
-   $ cp -r ./myapp-src/* ./parity/dapps/myapp/src/web
-   ```
-
-1. Instead of creating `web3` in your app. Load (as the first script tag in `head`):
-
-   ```html
-   <script src="/parity-utils/inject.js"></script>
-   ```
-
-   The `inject.js` script will create global `web3` instance with proper provider that should be used by your dapp.
-
-1. Create `./parity/dapps/myapp/Cargo.toml` with you apps details. See example here: [parity-status Cargo.toml](https://github.com/ethcore/parity-ui/blob/master/status/Cargo.toml).
-
-   ```bash
-   $ git clone https://github.com/ethcore/parity-ui.git
-   $ cd ./parity-ui/
-   $ cp ./home/Cargo.toml ../parity/dapps/myapp/Cargo.toml
-   $ cp ./home/build.rs ../parity/dapps/myapp/build.rs
-   $ cp ./home/src/lib.rs ../parity/dapps/myapp/src/lib.rs
-   $ cp ./home/src/lib.rs.in ../parity/dapps/myapp/src/lib.rs.in

-   $ vim ../parity/dapps/myapp/Cargo.toml # Edit the details
-   $ vim ./parity/dapps/myapp/src/lib.rs.in # Edit the details
-   ```
-# How to include your Dapp into `Parity`?
-1. Edit `dapps/Cargo.toml` and add dependency to your application (it can be optional)
-
-   ```toml
-   # Use git repo and version
-   parity-dapps-myapp = { path="./myapp" }
-   ```
-
-1. Edit `dapps/src/apps.rs` and add your application to `all_pages` (if it's optional you need to specify two functions - see `parity-dapps-wallet` example)
-
-1. Compile parity.
-
-   ```bash
-   $ cargo build --release # While inside `parity`
-   ```
-
-1. Commit the results.
-
-   ```bash
-   $ git add myapp && git commit -am "My first Parity Dapp".
-   ```

-//! Light client logic and implementation.
-//!
-//! A "light" client stores very little chain-related data locally
-//! unlike a full node, which stores all blocks, headers, receipts, and more.
-//!
-//! This enables the client to have a much lower resource footprint in
-//! exchange for the cost of having to ask the network for state data
-//! while responding to queries. This makes a light client unsuitable for
-//! low-latency applications, but perfectly suitable for simple everyday
-//! use-cases like sending transactions from a personal account.
-//!
-//! The light client performs a header-only sync, doing verification and pruning
-//! historical blocks. Upon pruning, batches of 2048 blocks have a number => hash
-//! mapping sealed into "canonical hash tries" which can later be used to verify
-//! historical block queries from peers.
