Implement Clique RPC APIs

[5chdn]

Parity Ethereum is a blockchain client and full-node implementation writting in Rust programming language. It supports multiple different chains based on the Ethereum Virtual Machine (EVM) or Parity's WebAssembly VM (pWasm). The client comes with "pluggable consensus," so it has different consensus engines, among others the "Ethash" proof-of-work engine, the "AuRa" proof-of-authority engine, and some developer presets like "Instant Seal" and "Basic Authority."

We want to add the "Clique" proof-of-authority engine to that list and allow users to synchronize the Rinkeby, Görli, and Kotti Classic testnets. The core of the work is mainly done (90%), what's missing is the "Clique" JSONRPC-APIs that allow users to control the engine via HTTP/WS/IPC APIs, namely:

• clique_discard

• clique_getSigners

• clique_getSignersAtHash

• clique_getSnapshot

• clique_getSnapshotAtHash

• clique_proposals

• clique_propose

• Compare the Geth (Go) implementation: https://github.com/ethereum/go-ethereum/blob/master/consensus/clique/api.go

• Compare the Pantheon (Java) implementation: https://docs.pantheon.pegasys.tech/en/stable/Reference/JSON-RPC-API-Methods/#clique-methods

... Profit? This task can be claimed via bounties. What is a bounty? That's a fixed amount of money that is claimable by anyone who is submitting a working solution to any of the tasks listed above and sufficient quality. What is sufficient quality? You certainly should have written Rust before and be familiar with the concepts and best practices of the language. Knowing Parity Ethereum or blockchain experience in general is a bonus.

Work has been started.

These users each claimed they can complete the work by 3 years ago.
Please review their action plans below:

1) thefallentree has applied to start work (Funders only: approve worker | reject worker).

I'm already looking into it and I've cleared my schedule to work on it. should be doable in next two weeks.
2) samparsky has been approved to start work.

I am quite familiar with Rust & Golang. This should take approximately 10- 14 days.
I have already started looking into this

@5chdn I have a couple of questions.

Is there a Gitter or discord channel to discuss?

[5chdn]

Yes, join https://gitter.im/goerli/clique

[KevinKelley]

Any help needed on this issue/bounty? I'm good in Rust, and fairly familiar with ethereum/parity, among other things

[thefallentree]

@5chdn i was going to work on this next, so what now?

[spm32]

Hi @thefallentree really appreciate your interest but it looks like @samparsky was accepted, unless he fails to deliver the task in 10-14 days as specified it won't open up again.

[samparsky]

@KevinKelley Ohh okay, I and @thefallentree are already collaborating together on the task. We will be sharing the bounty
