## Proposed Changes
- Log about eth1 whilst waiting for genesis.
- For the block and deposit caches, update them after each download instead of when *all* downloads are complete.
- This prevents the case where a single timeout error can cause us to drop *all* previously download blocks/deposits.
- Set `max_log_requests_per_update` to avoid timeouts due to very large log counts in a response.
- Set `max_blocks_per_update` to prevent a single update of the block cache to download an unreasonable number of blocks.
- This shouldn't have any affect in normal use, it's just a safe-guard against bugs.
- Increase the timeout for eth1 calls from 15s to 60s, as per @pawanjay176's experience with Infura.

This also brings with it a number of various improvements:
- Discv5 update
- Libp2p update
- Fix for recompilation issues
- Improved UPnP port mapping handling
- Futures dependency update
- Log downgrade to traces for rejecting peers when we've reached our max

## Issue Addressed
- Resolves#1424
## Proposed Changes
Add a `GET lighthouse/staking` that returns 200 if the node is ready to stake (i.e., `--eth1` flag is present) or a 404 otherwise.
Whilst the VC is waiting for the genesis time to start (i.e., when the genesis state is known), check the `lighthouse/staking` endpoint and log an error if the node isn't configured for staking.
## Additional Info
NA
## Issue Addressed
- Resolves#1945
## Proposed Changes
- As per #1945, fix a log message from the metrics server that was falsely claiming to be from the api server.
- Ensure successful api request logs are published to debug, not trace. This is something I've wanted to do for a while.

## Issue Addressed
Catching up on a few eth2 spec updates:
## Proposed Changes
- adding query params to the `GET pool/attestations` endpoint
- allowing the `POST pool/attestations` endpoint to accept an array of attestations
- batching attestation submission
- moving `epoch` from a path param to a query param in the `committees` endpoint

Resolves#1801
## Proposed Changes
Verify queries to `attestation_data` are for no later than `current_slot + 1`. If they are later than this, return a 400.

## Issue Addressed
- Related to #1691
## Proposed Changes
Adds the following API endpoints:
- `GET lighthouse/eth1/syncing`: status about how synced we are with Eth1.
- `GET lighthouse/eth1/block_cache`: all locally cached eth1 blocks.
- `GET lighthouse/eth1/deposit_cache`: all locally cached eth1 deposits.
Additionally:
- Moves some types from the `beacon_node/eth1` to the `common/eth2` crate, so they can be used in the API without duplication.
- Allow `update_deposit_cache` and `update_block_cache` to take an optional head block number to avoid duplicate requests.
## Additional Info
TBC
## Issue Addressed
Fixes head syncing
## Proposed Changes
- Get back to statusing peers after removing chain segments and making the peer manager deal with status according to the Sync status, preventing an old known deadlock
- Also a bug where a chain would get removed if the optimistic batch succeeds being empty
## Additional Info
Tested on Medalla and looking good
## Issue Addressed
Michael's comment here: https://github.com/sigp/lighthouse/issues/1434#issuecomment-708834079Resolves#1808
## Proposed Changes
- Add query param `id` and `status` to the `validators` endpoint
- Add string serialization and deserialization for `ValidatorStatus`
- Drop `Epoch` from `ValidatorStatus` variants
## Additional Info
Please provide any additional information. For example, future considerations
or information useful for reviewers.
## Issue Addressed
Potentially resolves#1647 and sync stalls.
## Proposed Changes
The handling of the state of banned peers was inadequate for the complex peerdb data structure. We store a limited number of disconnected and banned peers in the db. We were not tracking intermediate "disconnecting" states and the in some circumstances we were updating the peer state without informing the peerdb. This lead to a number of inconsistencies in the peer state.
Further, the peer manager could ban a peer changing a peer's state from being connected to banned. In this circumstance, if the peer then disconnected, we didn't inform the application layer, which lead to applications like sync not being informed of a peers disconnection. This could lead to sync stalling and having to require a lighthouse restart.
Improved handling for peer states and interactions with the peerdb is made in this PR.
## Issue Addressed
NA
## Proposed Changes
Adds a `lighthouse/beacon/states/:state_id/ssz` endpoint to allow us to pull the genesis state from the API.
## Additional Info
NA
## Issue Addressed
- Resolves#1766
## Proposed Changes
- Use the `warp::filters::cors` filter instead of our work-around.
## Additional Info
It's not trivial to enable/disable `cors` using `warp`, since using `routes.with(cors)` changes the type of `routes`. This makes it difficult to apply/not apply cors at runtime. My solution has been to *always* use the `warp::filters::cors` wrapper but when cors should be disabled, just pass the HTTP server listen address as the only permissible origin.
## Issue Addressed
`node` endpoints in #1434
## Proposed Changes
Implement these:
```
/eth/v1/node/health
/eth/v1/node/peers/{peer_id}
/eth/v1/node/peers
```
- Add an `Option<Enr>` to `PeerInfo`
- Finish implementation of `/eth/v1/node/identity`
## Additional Info
- should update the `peers` endpoints when #1764 is resolved

## Additional Info

## Issue Addressed
#1614 and a couple of sync-stalling problems, the most important is a cyclic dependency between the sync manager and the peer manager
## Issue Addressed
NA
## Proposed Changes
- Implements a HTTP API for the validator client.
- Creates EIP-2335 keystores with an empty `description` field, instead of a missing `description` field. Adds option to set name.
- Be more graceful with setups without any validators (yet)
- Remove an error log when there are no validators.
- Create the `validator` dir if it doesn't exist.
- Allow building a `ValidatorDir` without a withdrawal keystore (required for the API method where we only post a voting keystore).
- Add optional `description` field to `validator_definitions.yml`
## TODO
- [x] Signature header, as per https://github.com/sigp/lighthouse/issues/1269#issuecomment-649879855
- [x] Return validator descriptions
- [x] Return deposit data

- Includes the `ShufflingId` struct initially defined in #1492. That PR is now closed and the changes are included here, with significant bug fixes.
- Implement the https://github.com/ethereum/eth2.0-APIs in a new `http_api` crate using `warp`. This replaces the `rest_api` crate.
- Add a new `common/eth2` crate which provides a wrapper around `reqwest`, providing the HTTP client that is used by the validator client and for testing. This replaces the `common/remote_beacon_node` crate.
- Create a `http_metrics` crate which is a dedicated server for Prometheus metrics (they are no longer served on the same port as the REST API). We now have flags for `--metrics`, `--metrics-address`, etc.
- Allow the `subnet_id` to be an optional parameter for `VerifiedUnaggregatedAttestation::verify`. This means it does not need to be provided unnecessarily by the validator client.
- Move `fn map_attestation_committee` in `mod beacon_chain::attestation_verification` to a new `fn with_committee_cache` on the `BeaconChain` so the same cache can be used for obtaining validator duties.
- Add some other helpers to `BeaconChain` to assist with common API duties (e.g., `block_root_at_slot`, `head_beacon_block_root`).
- Change the `NaiveAggregationPool` so it can index attestations by `hash_tree_root(attestation.data)`. This is a requirement of the API.
- Add functions to `BeaconChainHarness` to allow it to create slashings and exits.
- Allow for `eth1::Eth1NetworkId` to go to/from a `String`.
- Add functions to the `OperationPool` to allow getting all objects in the pool.
- Add function to `BeaconState` to check if a committee cache is initialized.
- Fix bug where `seconds_per_eth1_block` was not transferring over from `YamlConfig` to `ChainSpec`.
- Add the `deposit_contract_address` to `YamlConfig` and `ChainSpec`. We needed to be able to return it in an API response.
- Change some uses of serde `serialize_with` and `deserialize_with` to a single use of `with` (code quality).
- Impl `Display` and `FromStr` for several BLS fields.
- Check for clock discrepancy when VC polls BN for sync state (with +/- 1 slot tolerance). This is not intended to be comprehensive, it was just easy to do.
- See #1434 for a per-endpoint overview.
- Seeking clarity here: https://github.com/ethereum/eth2.0-APIs/issues/75
