#2883
## Proposed Changes
* Added `suggested-fee-recipient` & `suggested-fee-recipient-file` flags to validator client (similar to graffiti / graffiti-file implementation).
* Added proposer preparation service to VC, which sends the fee-recipient of all known validators to the BN via [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api once per slot
* Added [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api endpoint and preparation data caching
* Added cleanup routine to remove cached proposer preparations when not updated for 2 epochs
## Additional Info
Changed the Implementation following the discussion in #2883.

## Issue Addressed
On a network with few nodes, it is possible that the same node can be found from a subnet discovery and a normal peer discovery at the same time.
The network behaviour loads these peers into events and processes them when it has the chance. It can happen that the same peer can enter the event queue more than once and then attempt to be dialed twice.
This PR shifts the registration of nodes in the peerdb as being dialed before they enter the NetworkBehaviour queue, preventing multiple attempts of the same peer being entered into the queue and avoiding the race condition.
## Issue Addressed
#2947
## Proposed Changes
Store messages that fail to be published due to insufficient peers for retry later. Messages expire after half an epoch and are retried if gossipsub informs us that an useful peer has connected. Currently running in Atlanta
## Additional Info
If on retry sending the messages fails they will not be tried again

## Proposed Changes
Adds `STRICT_LATE_MESSAGE_PENALTIES: bool` which allows for toggling penalties for late sync/attn messages.
`STRICT_LATE_MESSAGE_PENALTIES` is set to `false`, since we're seeing a lot of late messages on the network which are causing peer drops. We can toggle the bool during testing to try and figure out what/who is the cause of these late messages.
In effect, this PR *relaxes* peer downscoring for late attns and sync committee messages.
## Additional Info
- ~~Blocked on #2974~~
## Issue Addressed
Closes#2938
## Proposed Changes
* Build and publish images with a `-modern` suffix which enable CPU optimizations for modern hardware.
* Add docs for the plethora of available images!
* Unify all the Docker workflows in `docker.yml` (including for tagged releases).
## Additional Info
The `Dockerfile` is no longer used by our Docker Hub builds, as we use `cross` and a generic approach for ARM and x86. There's a new CI job `docker-build-from-source` which tests the `Dockerfile` without publishing anything.
The gossipsub history was increased to a good portion of a slot from 2.1 seconds in the last release.
Although it shouldn't cause too much issue, it could be related to recieving later messages than usual and interacting with our scoring system penalizing peers. For consistency, this PR reduces the time we gossip messages back to the same values of the previous release.
It also adjusts the gossipsub heartbeat time for testing purposes with a developer flag but this should not effect end users.
## Issue Addressed
N/A
## Proposed Changes
https://github.com/sigp/lighthouse/pull/2940 introduced a bug where we parsed the uint256 terminal total difficulty as a hex string instead of a decimal string. Fixes the bug and adds tests.
## Issue Addressed
Implements the standard key manager API from https://ethereum.github.io/keymanager-APIs/, formerly https://github.com/ethereum/beacon-APIs/pull/151
Related to https://github.com/sigp/lighthouse/issues/2557
## Proposed Changes
- [x] Add all of the new endpoints from the standard API: GET, POST and DELETE.
- [x] Add a `validators.enabled` column to the slashing protection database to support atomic disable + export.
- [x] Add tests for all the common sequential accesses of the API
- [x] Add tests for interactions with remote signer validators
- [x] Add end-to-end tests for migration of validators from one VC to another
- [x] Implement the authentication scheme from the standard (token bearer auth)
## Additional Info
The `enabled` column in the validators SQL database is necessary to prevent a race condition when exporting slashing protection data. Without the slashing protection database having a way of knowing that a key has been disabled, a concurrent request to sign a message could insert a new record into the database. The `delete_concurrent_with_signing` test exercises this code path, and was indeed failing before the `enabled` column was added.
The validator client authentication has been modified from basic auth to bearer auth, with basic auth preserved for backwards compatibility.
## Proposed Changes
Add a new hardcoded spec for the Gnosis Beacon Chain.
Ideally, official Lighthouse executables will be able to connect to the gnosis beacon chain from now on, using `--network gnosis` CLI option.
## Issue Addressed
This PR fixes the unnecessary `WARN Single block lookup failed` messages described here:
https://github.com/sigp/lighthouse/pull/2866#issuecomment-1008442640
## Proposed Changes
Add a new cache to the `BeaconChain` that tracks the block roots of blocks from before finalization. These could be blocks from the canonical chain (which might need to be read from disk), or old pre-finalization blocks that have been forked out.
The cache also stores a set of block roots for in-progress single block lookups, which duplicates some of the information from sync's `single_block_lookups` hashmap:
a836e180f9/beacon_node/network/src/sync/manager.rs (L192-L196)
On a live node you can confirm that the cache is working by grepping logs for the message: `Rejected attestation to finalized block`.
## Issue Addressed
N/A
## Proposed Changes
Add a HTTP API which can be used to compute the attestation performances of a validator (or all validators) over a discrete range of epochs.
Performances can be computed for a single validator, or for the global validator set.
## Usage
### Request
The API can be used as follows:
```
curl "http://localhost:5052/lighthouse/analysis/attestation_performance/{validator_index}?start_epoch=57730&end_epoch=57732"
```
Alternatively, to compute performances for the global validator set:
```
curl "http://localhost:5052/lighthouse/analysis/attestation_performance/global?start_epoch=57730&end_epoch=57732"
```
### Response
The response is JSON formatted as follows:
```
[
{
"index": 72,
"epochs": {
"57730": {
"active": true,
"head": false,
"target": false,
"source": false
},
"57731": {
"active": true,
"head": true,
"target": true,
"source": true,
"delay": 1
},
"57732": {
"active": true,
"head": true,
"target": true,
"source": true,
"delay": 1
},
}
}
]
```
> Note that the `"epochs"` are not guaranteed to be in ascending order.
## Additional Info
- This API is intended to be used in our upcoming validator analysis tooling (#2873) and will likely not be very useful for regular users. Some advanced users or block explorers may find this API useful however.
- The request range is limited to 100 epochs (since the range is inclusive and it also computes the `end_epoch` it's actually 101 epochs) to prevent Lighthouse using exceptionally large amounts of memory.
## Issue Addressed
Currently performing a voluntary exit prompts for manual confirmation. This prevents automation of exits.
## Proposed Changes
Add the flag `--no-confirmation` to the account manager when performing voluntary exits to bypass this manual confirmation.
## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/2857
## Proposed Changes
Explicitly set GNU malloc's MMAP_THRESHOLD to 128KB, disabling dynamic adjustments. For rationale see the linked issue.
Checking how to priorize the polling of the network I moved most of the service code to functions. This change I think it's worth on it's own for code quality since inside the `tokio::select` many tools don't work (cargo fmt, sometimes clippy, and sometimes even the compiler's errors get wack). This is functionally equivalent to the previous code, just better organized
## Proposed Changes
Initially the idea was to remove hashing of blocks in backfill sync. After considering it more, we conclude that we need to do it in both (forward and backfill) anyway. But since we forgot why we were doing it in the first place, this PR documents this logic.
Future us should find it useful

## Proposed Changes
Remove the check for exact equality on the beacon node spec when polling `/config/spec` from the VC. This check was always overzealous, and mostly served to check that the BN was configured for upcoming forks. I've replaced it by explicit checks of the `altair_fork_epoch` and `bellatrix_fork_epoch` instead.
## Additional Info
We should come back to this and clean it up so that we can retain compatibility while removing the field `default`s we installed.
In the latest release we decreased the target number of subnet peers.
It appears this could be causing issues in some cases and so reverting it back to the previous number it wise. A larger PR that follows this will address some other related discovery issues and peer management around subnet peer discovery.
## Proposed Changes
This PR establishes compatibility between Lighthouse's VC and Nimbus's BN.
Lighthouse was previously `POST`ing unquoted lists of validator indices to the attester and sync duties endpoints which were (correctly) not accepted by Nimbus. These lists had slipped through the cracks because they didn't have an explicit wrapper type to add `serde` annotations to. I've added the `ValidatorIndexDataRef` newtype in order to implement the modified serialisation behaviour.
## Testing
Combined with https://github.com/sigp/lighthouse/pull/2940, I've confirmed that this PR allows my Lighthouse VC on Prater to validate with the public Nimbus BN listed here: https://github.com/status-im/nimbus-eth2#quickly-test-your-tooling-against-nimbus. I haven't had a block proposal yet, but attestations and sync committee messages are working.
## Additional Info
This may also provide compatibility with Prysm BNs but I haven't had a chance to test that yet.
## Issue Addressed
Continuation to #2934
## Proposed Changes
Currently, we have the transition fields in the config (`TERMINAL_TOTAL_DIFFICULTY`, `TERMINAL_BLOCK_HASH` and `TERMINAL_BLOCK_HASH_ACTIVATION_EPOCH`) as mandatory fields.
This is causing compatibility issues with other client BN's (nimbus and teku v22.1.0) which don't return these fields on a `eth/v1/config/spec` api call. Since we don't use this values until the merge, I think it's okay to have default values set for these fields as well to ensure compatibility.
#2923
Which issue # does this PR address?
There's a redundant field on the BeaconChain called disabled_forks that was once part of our fork-aware networking (#953) but which is no longer used and could be deleted. so Removed all references to disabled_forks so that the code compiles and git grep disabled_forks returns no results.
## Proposed Changes
Please list or describe the changes introduced by this PR.
Removed all references of disabled_forks

## Issue Addressed
We emit a warning to verify that all peer connection state information is consistent. A warning is given under one edge case;
We try to dial a peer with peer-id X and multiaddr Y. The peer responds to multiaddr Y with a different peer-id, Z. The dialing to the peer fails, but libp2p injects the failed attempt as peer-id Z.
In this instance, our PeerDB tries to add a new peer in the disconnected state under a previously unknown peer-id. This is harmless and so this PR permits this behaviour without logging a warning.
## Issue Addressed
#2900
## Proposed Changes
Change type of extra_fields in ConfigAndPreset so it can contain non string values (inside serde_json::Value)
## Issues Addressed
Closes#2739Closes#2812
## Proposed Changes
Support the deserialization of query strings containing duplicate keys into their corresponding types.
As `warp` does not support this feature natively (as discussed in #2739), it relies on the external library [`serde_array_query`](https://github.com/sigp/serde_array_query) (written by @michaelsproul)
This is backwards compatible meaning that both of the following requests will produce the same output:
```
curl "http://localhost:5052/eth/v1/events?topics=head,block"
```
```
curl "http://localhost:5052/eth/v1/events?topics=head&topics=block"
```
## Additional Info
Certain error messages have changed slightly. This only affects endpoints which accept multiple values.
For example:
```
{"code":400,"message":"BAD_REQUEST: invalid query: Invalid query string","stacktraces":[]}
```
is now
```
{"code":400,"message":"BAD_REQUEST: unable to parse query","stacktraces":[]}
```
The serve order of the endpoints `get_beacon_state_validators` and `get_beacon_state_validators_id` have flipped:
```rust
.or(get_beacon_state_validators_id.boxed())
.or(get_beacon_state_validators.boxed())
```
This is to ensure proper error messages when filter fallback occurs due to the use of the `and_then` filter.
## Future Work
- Cleanup / remove filter fallback behaviour by substituting `and_then` with `then` where appropriate.
- Add regression tests for HTTP API error messages.
## Credits
- @mooori for doing the ground work of investigating possible solutions within the existing Rust ecosystem.
- @michaelsproul for writing [`serde_array_query`](https://github.com/sigp/serde_array_query) and for helping debug the behaviour of the `warp` filter fallback leading to incorrect error messages.
## Proposed Changes
Restore compatibility with beacon nodes using the `MERGE` naming by:
1. Adding defaults for the Bellatrix `Config` fields
2. Not attempting to read (or serve) the Bellatrix preset on `/config/spec`.
I've confirmed that this works with Infura, and just logs a warning:
```
Jan 20 10:51:31.078 INFO Connected to beacon node endpoint: https://eth2-beacon-mainnet.infura.io/, version: teku/v22.1.0/linux-x86_64/-eclipseadoptium-openjdk64bitservervm-java-17
Jan 20 10:51:31.344 WARN Beacon node config does not match exactly, advice: check that the BN is updated and configured for any upcoming forks, endpoint: https://eth2-beacon-mainnet.infura.io/
Jan 20 10:51:31.344 INFO Initialized beacon node connections available: 1, total: 1
```
## Proposed Changes
Change the canonical fork name for the merge to Bellatrix. Keep other merge naming the same to avoid churn.
I've also fixed and enabled the `fork` and `transition` tests for Bellatrix, and the v1.1.7 fork choice tests.
Additionally, the `BellatrixPreset` has been added with tests. It gets served via the `/config/spec` API endpoint along with the other presets.
## Issue Addressed

## Proposed Changes
Since we use the `rc` (release candidate) tag in our version strings, it seems consistent if we also use "release candidate" in the book rather than "pre-release".
Notably, Github adds a "pre-release" tag to release when we request. I think it's OK that Github uses that term whilst we consistently use "release candidate". Our docs indicate that the terms are interchangeable.
## Additional Info
I hope to use the new docs link in the `v2.1.0` release, so it would be nice if we can merge this soon 🙏
## Issue Addressed

## Proposed Changes
In https://github.com/sigp/lighthouse/pull/2832 we made some changes to the `SnapshotCache` to help deal with the one-block reorgs seen on mainnet (and testnets).
I believe the change in #2832 is good and we should keep it, but I think that in its present form it is causing the `SnapshotCache` to hold onto states that it doesn't need anymore. For example, a skip slot will result in one more `BeaconSnapshot` being stored in the cache.
This PR adds a new type of pruning that happens after a block is inserted to the cache. We will remove any snapshot from the cache that is a *grandparent* of the block being imported. Since we know the grandparent has two valid blocks built atop it, it is not at risk from a one-block re-org.
## Additional Info
NA
## Proposed Changes
Allocate less memory in sync by hashing the `SignedBeaconBlock`s in a batch directly, rather than going via SSZ bytes.
Credit to @paulhauner for finding this source of temporary allocations.
## Issue Addressed
The PeerDB was getting out of sync with the number of disconnected peers compared to the actual count. As this value determines how many we store in our cache, over time the cache was depleting and we were removing peers immediately resulting in errors that manifest as unknown peers for some operations.
The error occurs when dialing a peer fails, we were not correctly updating the peerdb counter because the increment to the counter was placed in the wrong order and was therefore not incrementing the count.
This PR corrects this.
