## 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).

#3723
## Proposed Changes
Adds a new CLI flag `--gui` which enables all the various flags required for the gui to function properly.
Currently enables the `--http` and `--validator-monitor-auto` flags.
## Issue Addressed
Partially addresses #3651
## 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.

## Issue Addressed
NA
## Proposed Changes
- Bump versions
- Pin the `nethermind` version since our method of getting the latest tags on `master` is giving us an old version (`1.14.1`).
- Increase timeout for execution engine startup.
## Additional Info
- [x] ~Awaiting further testing~
## Issue Addressed
Partially addresses #3707
## Proposed Changes
Drop `ERRO` log to `WARN` until we identify the exact conditions that lead to this case.
Add a message which hopefully reassures users who only see this log once 😅
Add the block hash to the error message in case it will prove useful in debugging the root cause.

## Proposed Changes
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.
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
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()`.

## 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.
