This is an out of tree EIP225 (Clique Proof-of authority consensus engine) implementation for Parity. This implementation is mostly authored by Yucong Sun, and there is some other changes pulled in from peoples noted in credits. It is also the software version in use in my active Goerli authority node (Yucong Sun Authority as seen in https://explorer.goerli.net/).

• Sync & full block validation for clique based ethereum networks.
• Seal blocks and process votes according to EIP225 rules.
• built-in genesis JSON files for easily connecting to Rinkeby, Goerli, and Kotti network.

• an tool to generate genesis json file for clique engine.
• JSON rpc for voting.

• connect to rinkeby network by ./parity --chain rinkeby
• connect to goerli and kotti network.
• Run an local Clique based ethereum network with parity alone (tutorial pending)
• Join an cross client Clique based ethereum network as an Full Node, together with Geth, Pantheon and other clients.

This patch will be updated in best effort to keep up with latest release from paritytech/partity-ethereum, but will not be upstreamed. (see goerli/parity-goerli#44 for context).

If you want to make a feature request, please raise a issue.

genesis JSON files for Goerli & Kotti are from @5chdn.
