## Proposed Changes
Update the Gnosis chain bootnodes. The current list of Gnosis bootnodes were abandoned at some point before the Gnosis merge and are now failing to bootstrap peers. There's a workaround list of bootnodes here: https://docs.gnosischain.com/updates/20221208-temporary-bootnodes
The list from this PR represents the long-term bootnodes run by the Gnosis team. We will also try to set up SigP bootnodes for Gnosis chain at some point.
## Proposed Changes
With proposer boosting implemented (#2822) we have an opportunity to re-org out late blocks.
This PR adds three flags to the BN to control this behaviour:
* `--disable-proposer-reorgs`: turn aggressive re-orging off (it's on by default).
* `--proposer-reorg-threshold N`: attempt to orphan blocks with less than N% of the committee vote. If this parameter isn't set then N defaults to 20% when the feature is enabled.
* `--proposer-reorg-epochs-since-finalization N`: only attempt to re-org late blocks when the number of epochs since finalization is less than or equal to N. The default is 2 epochs, meaning re-orgs will only be attempted when the chain is finalizing optimally.
For safety Lighthouse will only attempt a re-org under very specific conditions:
1. The block being proposed is 1 slot after the canonical head, and the canonical head is 1 slot after its parent. i.e. at slot `n + 1` rather than building on the block from slot `n` we build on the block from slot `n - 1`.
2. The current canonical head received less than N% of the committee vote. N should be set depending on the proposer boost fraction itself, the fraction of the network that is believed to be applying it, and the size of the largest entity that could be hoarding votes.
3. The current canonical head arrived after the attestation deadline from our perspective. This condition was only added to support suppression of forkchoiceUpdated messages, but makes intuitive sense.
4. The block is being proposed in the first 2 seconds of the slot. This gives it time to propagate and receive the proposer boost.

## Issue Addressed
NA
## Proposed Changes
This is a *potentially* contentious change, but I find it annoying that the validator monitor logs `WARN` and `ERRO` for imperfect attestations. Perfect attestation performance is unachievable (don't believe those photo-shopped beauty magazines!) since missed and poorly-packed blocks by other validators will reduce your performance.
When the validator monitor is on with 10s or more validators, I find the logs are washed out with ERROs that are not worth investigating. I suspect that users who really want to know if validators are missing attestations can do so by matching the content of the log, rather than the log level.
I'm open to feedback about this, especially from anyone who is relying on the current log levels.
## Additional Info
NA
## Breaking Changes Notes
The validator monitor will no longer emit `WARN` and `ERRO` logs for sub-optimal attestation performance. The logs will now be emitted at `INFO` level. This change was introduced to avoid cluttering the `WARN` and `ERRO` logs with alerts that are frequently triggered by the actions of other network participants (e.g., a missed block) and require no action from the user.
## Issue Addressed
Implementing the light_client_gossip topics but I'm not there yet.
Which issue # does this PR address?
Partially #3651
## Proposed Changes
Add light client gossip topics.
Please list or describe the changes introduced by this PR.
I'm going to Implement light_client_finality_update and light_client_optimistic_update gossip topics. Currently I've attempted the former and I'm seeking feedback.
## Additional Info
I've only implemented the light_client_finality_update topic because I wanted to make sure I was on the correct path. Also checking that the gossiped LightClientFinalityUpdate is the same as the locally constructed one is not implemented because caching the updates will make this much easier. Could someone give me some feedback on this please?
Please provide any additional information. For example, future considerations
or information useful for reviewers.

## Issue Addressed
NA
## Proposed Changes
In #3725 I introduced a `CRIT` log for unrevealed payloads, against @michaelsproul's [advice](https://github.com/sigp/lighthouse/pull/3725#discussion_r1034142113). After being woken up in the middle of the night by a block that was not revealed to the BN but *was* revealed to the network, I have capitulated. This PR implements @michaelsproul's suggestion and reduces the severity to `ERRO`.
Additionally, I have dropped a `CRIT` to an `ERRO` for when a block is published late. The block in question was indeed published late on the network, however now that we have builders that can slow down block production I don't think the error is "actionable" enough to warrant a `CRIT` for the user.
## Additional Info
NA
## Issue Addressed
#3766
## Proposed Changes
Adds an endpoint to get the graffiti that will be used for the next block proposal for each validator.
## Usage
```bash
curl -H "Authorization: Bearer api-token" http://localhost:9095/lighthouse/ui/graffiti | jq
```
```json
{
"data": {
"0x81283b7a20e1ca460ebd9bbd77005d557370cabb1f9a44f530c4c4c66230f675f8df8b4c2818851aa7d77a80ca5a4a5e": "mr f was here",
"0xa3a32b0f8b4ddb83f1a0a853d81dd725dfe577d4f4c3db8ece52ce2b026eca84815c1a7e8e92a4de3d755733bf7e4a9b": "mr v was here",
"0x872c61b4a7f8510ec809e5b023f5fdda2105d024c470ddbbeca4bc74e8280af0d178d749853e8f6a841083ac1b4db98f": null
}
}
```
## Additional Info
This will only return graffiti that the validator client knows about.
That is from these 3 sources:
1. Graffiti File
2. validator_definitions.yml
3. The `--graffiti` flag on the VC
If the graffiti is set on the BN, it will not be returned. This may warrant an additional endpoint on the BN side which can be used in the event the endpoint returns `null`.
## Proposed Changes
Adds docs for the following endpoints:
- `/lighthouse/analysis/attestation_performance`
- `/lighthouse/analysis/block_packing_efficiency`
## Issue Addressed
#3724
## Proposed Changes
Exposes certain `validator_monitor` as an endpoint on the HTTP API. Will only return metrics for validators which are actively being monitored.
### Usage
```bash
curl -X GET "http://localhost:5052/lighthouse/ui/validator_metrics" -H "accept: application/json" | jq
```
```json
{
"data": {
"validators": {
"12345": {
"attestation_hits": 10,
"attestation_misses": 0,
"attestation_hit_percentage": 100,
"attestation_head_hits": 10,
"attestation_head_misses": 0,
"attestation_head_hit_percentage": 100,
"attestation_target_hits": 5,
"attestation_target_misses": 5,
"attestation_target_hit_percentage": 50
}
}
}
}
```
## Additional Info
Based on #3756 which should be merged first.
## Proposed Changes
Now that the Gnosis merge is scheduled, all users should have upgraded beyond Lighthouse v3.0.0. Accordingly we can delete schema migrations for versions prior to v3.0.0.
## Additional Info
I also deleted the state cache stuff I added in #3714 as it turned out to be useless for the light client proofs due to the one-slot offset.
## Issue Addressed
#3724
## Proposed Changes
Adds an endpoint to quickly count the number of occurances of each status in the validator set.
## Usage

```
```json
{
"data": {
"active_ongoing":479508,

## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/2327
## Proposed Changes
This is an extension of some ideas I implemented while working on `tree-states`:
- Cache the indexed attestations from blocks in the `ConsensusContext`. Previously we were re-computing them 3-4 times over.
- Clean up `import_block` by splitting each part into `import_block_XXX`.
- Move some stuff off hot paths, specifically:
- Relocate non-essential tasks that were running between receiving the payload verification status and priming the early attester cache. These tasks are moved after the cache priming:
- Attestation observation
- Validator monitor updates
- Slasher updates
- Updating the shuffling cache
- Fork choice attestation observation now happens at the end of block verification in parallel with payload verification (this seems to save 5-10ms).
- Payload verification now happens _before_ advancing the pre-state and writing it to disk! States were previously being written eagerly and adding ~20-30ms in front of verifying the execution payload. State catchup also sometimes takes ~500ms if we get a cache miss and need to rebuild the tree hash cache.
The remaining task that's taking substantial time (~20ms) is importing the block to fork choice. I _think_ this is because of pull-tips, and we should be able to optimise it out with a clever total active balance cache in the state (which would be computed in parallel with payload verification). I've decided to leave that for future work though. For now it can be observed via the new `beacon_block_processing_post_exec_pre_attestable_seconds` metric.

## Issue Addressed
our bootnodes as of now support only ipv4. this makes it so that they support ipv6
## Proposed Changes
- Adds code necessary to update the bootnodes to run on dual stack nodes and therefore contact and store ipv6 nodes.
- Adds some metrics about connectivity type of stored peers. It might have been nice to see some metrics over the sessions but that feels out of scope right now.
## Additional Info
- some code quality improvements sneaked in since the changes seemed small
- I think it depends on the OS, but enabling mapped addresses on an ipv6 node without dual stack support enabled could fail silently, making these nodes effectively ipv6 only. In the future I'll probably change this to use two sockets, which should fail loudly
## Issue Addressed
#3704
## Proposed Changes
Adds is_syncing_finalized: bool parameter for block verification functions. Sets the payload_verification_status to Optimistic if is_syncing_finalized is true. Uses SyncState in NetworkGlobals in BeaconProcessor to retrieve the syncing status.
## Additional Info
I could implement FinalizedSignatureVerifiedBlock if you think it would be nicer.
## Issue Addressed
NA
## Proposed Changes
This PR sets out to improve the logging/metrics experience when interacting with the builder. Namely, it:
- Adds/changes metrics (see "Metrics Changes" section).
- Adds new logs which show the duration of requests to the builder/local EL.
- Refactors existing logs for consistency and so that the `parent_hash` is include in all relevant logs (we can grep for this field when trying to trace the flow of block production).
Additionally, when I was implementing this PR I noticed that we skip some verification of the builder payload in the scenario where the builder return `Ok` but the local EL returns with `Err`. Namely, we were skipping the bid signature and other values like parent hash and prev randao. In this PR I've changed it so we *always* check these values and reject the bid if they're incorrect. With these changes, we'll sometimes choose to skip a proposal rather than propose something invalid -- that's the only side-effect to the changes that I can see.
## Metrics Changes
- Changed: `execution_layer_request_times`:
- `method = "get_blinded_payload_local"`: time taken to get a payload from a local EE.
- `method = "get_blinded_payload_builder"`: time taken to get a blinded payload from a builder.
- `method = "post_blinded_payload_builder"`: time taken to get a builder to reveal a payload they've previously supplied us.
- `execution_layer_get_payload_outcome`
- `outcome = "success"`: we successfully produced a payload from a builder or local EE.
- `outcome = "failure"`: we were unable to get a payload from a builder or local EE.
- New: `execution_layer_builder_reveal_payload_outcome`
- `outcome = "success"`: a builder revealed a payload from a signed, blinded block.
- `outcome = "failure"`: the builder did not reveal the payload.
- New: `execution_layer_get_payload_source`
- `type = "builder"`: we used a payload from a builder to produce a block.
- `type = "local"`: we used a payload from a local EE to produce a block.
- New: `execution_layer_get_payload_builder_rejections` has a `reason` field to describe why we rejected a payload from a builder.
- New: `execution_layer_payload_bids` tracks the bid (in gwei) from the builder or local EE (local EE not yet supported, waiting on EEs to expose the value). Can only record values that fit inside an i64 (roughly 9 million ETH).

## Proposed Changes
- Added a guide to run a node. Mainly, copy and paste from 'Merge Migration' and 'Checkpoint Sync'.
- Ranked it high in ToC:
- Introduction

- Run a Node
- Become a Validator
...
- Hid 'Merge Migration' in ToC.
## Additional Info
- Should I add/rephrase/delete something?
- Now there is some redundancy:
- 'Run a node' and 'Checkpoint Sync' contain similar information.
- Same for 'Run a node' and 'Become a Validator'.

## Proposed Changes
Add a CLI flag to allow users to opt out of the restrictive permissions of the log files.
## Additional Info
This is not recommended for most users. The log files can contain sensitive information such as validator indices, public keys and API tokens (see #2438). However some users using a multi-user setup may find this helpful if they understand the risks involved.

## Proposed Changes
Adds server-side support for light_client_bootstrap_v1 topic
## Additional Info
This PR, creates each time a bootstrap without using cache, I do not know how necessary a cache is in this case as this topic is not supposed to be called frequently and IMHO we can just prevent abuse by using the limiter, but let me know what you think or if there is any caveat to this, or if it is necessary only for the sake of good practice.

With a few different changes to the gossip topics in flight (light clients, Capella, 4844, etc) I think this simplification makes sense. I noticed it while plumbing through a new Capella topic.
## Issue Addressed
Closes#3709
## Proposed Changes
Add the job `compile-with-beta-compiler` to `test-suite`. This job has the following steps:
1. Use `actions/checkout@v3`. (Needed to run make in a later step.)
2. Install the dependencies listed in [build from source guide](https://lighthouse-book.sigmaprime.io/installation-source.html).
3. Change the compiler to the current beta version with `rustup override`.
4. Run `make`.
This PR adds some health endpoints for the beacon node and the validator client.
Specifically it adds the endpoint:
`/lighthouse/ui/health`
These are not entirely stable yet. But provide a base for modification for our UI.
These also may have issues with various platforms and may need modification.
## Issue Addressed

## Proposed Changes
* Replace `set-output` by `$GITHUB_OUTPUT` usage
* Avoid rate-limits when installing `protoc` by making authenticated requests (continuation of https://github.com/sigp/lighthouse/pull/3621)
* Upgrade all Ubuntu 18.04 usage to 22.04 (18.04 is end of life)
* Upgrade macOS-latest to explicit macOS-12 to silence warning
* Use `actions/checkout@v3` and `actions/cache@v3` to avoid deprecated NodeJS v12
## Additional Info
Can't silence the NodeJS warnings entirely due to https://github.com/sigp/lighthouse/issues/3705. Can fix that in future.
## Issue Addressed
Closes#3612
## Proposed Changes
- Iterates through BNs until it finds a non-optimistic head.
A slight change in error behavior:
- Previously: `spawn_contribution_tasks` did not return an error for a non-optimistic block head. It returned `Ok(())` logged a warning.
- Now: `spawn_contribution_tasks` returns an error if it cannot find a non-optimistic block head. The caller of `spawn_contribution_tasks` then logs the error as a critical error.

## Issue Addressed
Part of https://github.com/sigp/lighthouse/issues/3651.
## Proposed Changes
Add a flag for enabling the light client server, which should be checked before gossip/RPC traffic is processed (e.g. https://github.com/sigp/lighthouse/pull/3693, https://github.com/sigp/lighthouse/pull/3711). The flag is available at runtime from `beacon_chain.config.enable_light_client_server`.
Additionally, a new method `BeaconChain::with_mutable_state_for_block` is added which I envisage being used for computing light client updates. Unfortunately its performance will be quite poor on average because it will only run quickly with access to the tree hash cache. Each slot the tree hash cache is only available for a brief window of time between the head block being processed and the state advance at 9s in the slot. When the state advance happens the cache is moved and mutated to get ready for the next slot, which makes it no longer useful for merkle proofs related to the head block. Rather than spend more time trying to optimise this I think we should continue prototyping with this code, and I'll make sure `tree-states` is ready to ship before we enable the light client server in prod (cf. https://github.com/sigp/lighthouse/pull/3206).
## Additional Info
I also fixed a bug in the implementation of `BeaconState::compute_merkle_proof` whereby the tree hash cache was moved with `.take()` but never put back with `.restore()`.

## Issue Addressed
This PR addresses partially #3651
## Proposed Changes
This PR adds the following methods:
* a new method to trait `TreeHash`, `hash_tree_leaves` which returns all the Merkle leaves of the ssz object.
* a new method to `BeaconState`: `compute_merkle_proof` which generates a specific merkle proof for given depth and index by using the `hash_tree_leaves` as leaves function.
## Additional Info
Now here is some rationale on why I decided to go down this route: adding a new function to commonly used trait is a pain but was necessary to make sure we have all merkle leaves for every object, that is why I just added `hash_tree_leaves` in the trait and not `compute_merkle_proof` as well. although it would make sense it gives us code duplication/harder review time and we just need it from one specific object in one specific usecase so not worth the effort YET. In my humble opinion.

## Proposed Changes
Adds clarification to an error log when there is an error submitting a validator registration.
There seems to be a few cases where relays return errors during validator registration, including spurious timeouts and when a validator has been very recently activated/made pending.
Changing this log helps indicate that it's "just another registration error" rather than something more serious. I didn't drop this to a `WARN` since I still have hope we can eliminate these errors completely by chatting with relays and adjusting timeouts.

## Summary
The deposit cache now has the ability to finalize deposits. This will cause it to drop unneeded deposit logs and hashes in the deposit Merkle tree that are no longer required to construct deposit proofs. The cache is finalized whenever the latest finalized checkpoint has a new `Eth1Data` with all deposits imported.
This has three benefits:
1. Improves the speed of constructing Merkle proofs for deposits as we can just replay deposits since the last finalized checkpoint instead of all historical deposits when re-constructing the Merkle tree.
2. Significantly faster weak subjectivity sync as the deposit cache can be transferred to the newly syncing node in compressed form. The Merkle tree that stores `N` finalized deposits requires a maximum of `log2(N)` hashes. The newly syncing node then only needs to download deposits since the last finalized checkpoint to have a full tree.
3. Future proofing in preparation for [EIP-4444](https://eips.ethereum.org/EIPS/eip-4444) as execution nodes will no longer be required to store logs permanently so we won't always have all historical logs available to us.
## More Details
Image to illustrate how the deposit contract merkle tree evolves and finalizes along with the resulting `DepositTreeSnapshot`
## Other Considerations
I've changed the structure of the `SszDepositCache` so once you load & save your database from this version of lighthouse, you will no longer be able to load it from older versions.

## Issue Addressed
This PR partially addresses #3651
## Proposed Changes
This PR adds the following containers types from [the lightclient specs](https://github.com/ethereum/consensus-specs/blob/dev/specs/altair/light-client/sync-protocol.md): `LightClientUpdate`, `LightClientFinalityUpdate`, `LightClientOptimisticUpdate` and `LightClientBootstrap`. It also implements the creation of each updates as delined by this [document](https://github.com/ethereum/consensus-specs/blob/dev/specs/altair/light-client/full-node.md).
## Additional Info
Here is a brief description of what each of these container signify:
`LightClientUpdate`: This container is only provided by server (full node) to lightclients when catching up new sync committees beetwen periods and we want possibly one lightclient update ready for each post-altair period the lighthouse node go over. it is needed in the resp/req in method `light_client_update_by_range`.
`LightClientFinalityUpdate/LightClientFinalityUpdate`: Lighthouse will need only the latest of each of this kind of updates, so no need to store them in the database, we can just store the latest one of each one in memory and then just supply them via gossip or respreq, only the latest ones are served by a full node. finality updates marks the transition to a new finalized header, while optimistic updates signify new non-finalized header which are imported optimistically.
`LightClientBootstrap`: This object is retrieved by lightclients during the bootstrap process after a finalized checkpoint is retrieved, ideally we want to store a LightClientBootstrap for each finalized root and then serve each of them by finalized root in respreq protocol id `light_client_bootstrap`.
Little digression to how we implement the creation of each updates: the creation of a optimistic/finality update is just a version of the lightclient_update creation mechanism with less fields being set, there is underlying concept of inheritance, if you look at the specs it becomes very obvious that a lightclient update is just an extension of a finality update and a finality update an extension to an optimistic update.
## Extra note
`LightClientStore` is not implemented as it is only useful as internal storage design for the lightclient side.
## Issue Addressed
This reverts commit ca9dc8e094 (PR #3559) with some modifications.
## Proposed Changes
Unfortunately that PR introduced a performance regression in fork choice. The optimisation _intended_ to build the exit and pubkey caches on the head state _only if_ they were not already built. However, due to the head state always being cloned without these caches, we ended up building them every time the head changed, leading to a ~70ms+ penalty on mainnet.
fcfd02aeec/beacon_node/beacon_chain/src/canonical_head.rs (L633-L636)
I believe this is a severe enough regression to justify immediately releasing v3.2.1 with this change.
## Additional Info
I didn't fully revert #3559, because there were some unrelated deletions of dead code in that PR which I figured we may as well keep.
An alternative would be to clone the extra caches, but this likely still imposes some cost, so in the interest of applying a conservative fix quickly, I think reversion is the best approach. The optimisation from #3559 was not even optimising a particularly significant path, it was mostly for VCs running larger numbers of inactive keys. We can re-do it in the `tree-states` world where cache clones are cheap.

I noticed that [this build](https://github.com/sigp/lighthouse/actions/runs/3269950873/jobs/5378036501) wasn't marked failed by Bors when the `syncing-simulator-ubuntu` job failed. This is because that job is absent from the `bors.toml` config.
## Proposed Changes
Add missing jobs to Bors config so that they are required:
- `syncing-simulator-ubuntu`
- `slasher-tests`
- `disallowed-from-async-lint`
The `disallowed-from-async-lint` was previously allowed to fail because it was considered beta, but I think it's stable enough now we may as well require it.

Add execution_timeout_multiplier to the execution layer config as Option<u32> and pass the u32 to HttpJsonRpc.
## Additional Info
