Ethereum consensus client in Rust

## Issue Addressed #3031 ## Proposed Changes Updates the following API endpoints to conform with https://github.com/ethereum/beacon-APIs/pull/190 and https://github.com/ethereum/beacon-APIs/pull/196 - [x] `beacon/states/{state_id}/root` - [x] `beacon/states/{state_id}/fork` - [x] `beacon/states/{state_id}/finality_checkpoints` - [x] `beacon/states/{state_id}/validators` - [x] `beacon/states/{state_id}/validators/{validator_id}` - [x] `beacon/states/{state_id}/validator_balances` - [x] `beacon/states/{state_id}/committees` - [x] `beacon/states/{state_id}/sync_committees` - [x] `beacon/headers` - [x] `beacon/headers/{block_id}` - [x] `beacon/blocks/{block_id}` - [x] `beacon/blocks/{block_id}/root` - [x] `beacon/blocks/{block_id}/attestations` - [x] `debug/beacon/states/{state_id}` - [x] `debug/beacon/heads` - [x] `validator/duties/attester/{epoch}` - [x] `validator/duties/proposer/{epoch}` - [x] `validator/duties/sync/{epoch}` Updates the following Server-Sent Events: - [x] `events?topics=head` - [x] `events?topics=block` - [x] `events?topics=finalized_checkpoint` - [x] `events?topics=chain_reorg` ## Backwards Incompatible There is a very minor breaking change with the way the API now handles requests to `beacon/blocks/{block_id}/root` and `beacon/states/{state_id}/root` when `block_id` or `state_id` is the `Root` variant of `BlockId` and `StateId` respectively. Previously a request to a non-existent root would simply echo the root back to the requester: ``` curl "http://localhost:5052/eth/v1/beacon/states/0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/root" {"data":{"root":"0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"}} ``` Now it will return a `404`: ``` curl "http://localhost:5052/eth/v1/beacon/blocks/0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/root" {"code":404,"message":"NOT_FOUND: beacon block with root 0xaaaa…aaaa","stacktraces":[]} ``` In addition to this is the block root `0x0000000000000000000000000000000000000000000000000000000000000000` previously would return the genesis block. It will now return a `404`: ``` curl "http://localhost:5052/eth/v1/beacon/blocks/0x0000000000000000000000000000000000000000000000000000000000000000" {"code":404,"message":"NOT_FOUND: beacon block with root 0x0000…0000","stacktraces":[]} ``` ## Additional Info - `execution_optimistic` is always set, and will return `false` pre-Bellatrix. I am also open to the idea of doing something like `#[serde(skip_serializing_if = "Option::is_none")]`. - The value of `execution_optimistic` is set to `false` where possible. Any computation that is reliant on the `head` will simply use the `ExecutionStatus` of the head (unless the head block is pre-Bellatrix). Co-authored-by: Paul Hauner <paul@paulhauner.com> |

Lighthouse: Ethereum consensus client
An open-source Ethereum consensus client, written in Rust and maintained by Sigma Prime.
Overview
Lighthouse is:
- Ready for use on Ethereum consensus mainnet.
- Fully open-source, licensed under Apache 2.0.
- Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
- Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
- Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys, the Decentralization Foundation and private individuals.
- Actively involved in the specification and security analysis of the Ethereum proof-of-stake consensus specification.
Staking Deposit Contract
The Lighthouse team acknowledges
0x00000000219ab540356cBB839Cbe05303d7705Fa
as the canonical staking deposit contract address.
Documentation
The Lighthouse Book contains information for users and developers.
The Lighthouse team maintains a blog at lighthouse-blog.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.
Branches
Lighthouse maintains two permanent branches:
stable: Always points to the latest stable release.- This is ideal for most users.
unstable: Used for development, contains the latest PRs.- Developers should base their PRs on this branch.
Contributing
Lighthouse welcomes contributors.
If you are looking to contribute, please head to the Contributing section of the Lighthouse book.
