## Proposed Changes
Add the Holesky network config as per 36e4ff2d51/custom_config_data.
Since the genesis state is ~190MB, I've opted to *not* include it in the binary and instead download it at runtime (see #4564 for context). To download this file we have:
- A hard-coded URL for a SigP-hosted S3 bucket with the Holesky genesis state. Assuming this download works correctly, users will be none the wiser that the state wasn't included in the binary (apart from some additional logs)
- If the user provides a `--checkpoint-sync-url` flag, then LH will download the genesis state from that server rather than our S3 bucket.
- If the user provides a `--genesis-state-url` flag, then LH will download the genesis state from that server regardless of the S3 bucket or `--checkpoint-sync-url` flag.
- Whenever a genesis state is downloaded it is checked against a checksum baked into the binary.
- A genesis state will never be downloaded if it's already included in the binary.
- There is a `--genesis-state-url-timeout` flag to tweak the timeout for downloading the genesis state file.
## Log Output
Example of log output when a state is downloaded:

The genesis state is not present in the binary and there are no known download URLs. Please use --checkpoint-sync-url or --genesis-state-url.
```
## Additional Info
I tested the `--genesis-state-url` flag with all 9 Goerli checkpoint sync servers on https://eth-clients.github.io/checkpoint-sync-endpoints/ and they all worked 🎉
My IDE eagerly formatted some `Cargo.toml`. I've disabled it but I don't see the value in spending time reverting the changes that are already there.
I also added the `GenesisStateBytes` enum to avoid an unnecessary clone on the genesis state bytes baked into the binary. This is not a huge deal on Mainnet, but will become more relevant when testing with big genesis states.
When we do a fresh checkpoint sync we're downloading the genesis state to check the `genesis_validators_root` against the finalised state we receive. This is not *entirely* pointless, since we verify the checksum when we download the genesis state so we are actually guaranteeing that the finalised state is on the same network. There might be a smarter/less-download-y way to go about this, but I've run out of cycles to figure that out. Perhaps we can grab it in the next release?
## Issue Addressed
Upgrade libp2p to v0.52
## Proposed Changes
- **Workflows**: remove installation of `protoc`
- **Book**: remove installation of `protoc`
- **`Dockerfile`s and `cross`**: remove custom base `Dockerfile` for cross since it's no longer needed. Remove `protoc` from remaining `Dockerfiles`s
- **Upgrade `discv5` to `v0.3.1`:** we have some cool stuff in there: no longer needs `protoc` and faster ip updates on cold start
- **Upgrade `prometheus` to `0.21.0`**, now it no longer needs encoding checks
- **things that look like refactors:** bunch of api types were renamed and need to be accessed in a different (clearer) way
- **Lighthouse network**
- connection limits is now a behaviour
- banned peers no longer exist on the swarm level, but at the behaviour level
- `connection_event_buffer_size` now is handled per connection with a buffer size of 4
- `mplex` is deprecated and was removed
- rpc handler now logs the peer to which it belongs
## Additional Info
Tried to keep as much behaviour unchanged as possible. However, there is a great deal of improvements we can do _after_ this upgrade:
- Smart connection limits: Connection limits have been checked only based on numbers, we can now use information about the incoming peer to decide if we want it
- More powerful peer management: Dial attempts from other behaviours can be rejected early
- Incoming connections can be rejected early
- Banning can be returned exclusively to the peer management: We should not get connections to banned peers anymore making use of this
- TCP Nat updates: We might be able to take advantage of confirmed external addresses to check out tcp ports/ips

## Proposed Changes
- Fix bad `state_root` reuse in `lcli transition-blocks` that resulted in invalid results at skipped slots.
- Modernise `lcli pretty-ssz` to include fork-generic decoders for `SignedBeaconBlock` and `BeaconState` which respect the `--network`/`--testnet-dir` flag.
## Additional Info
Breaking change: the underscore names like `signed_block_merge` are removed in favour of the fork-generic name `SignedBeaconBlock`, and fork-specific names which match the superstruct variants, e.g. `SignedBeaconBlockMerge`.

## Additional Info

## Proposed Changes
* Add `lcli state-root` command for computing the hash tree root of a `BeaconState`.
* Add a `--network` flag which can be used instead of `--testnet-dir` to set the network, e.g. Mainnet, Goerli, Gnosis.
* Use the new network flag in `transition-blocks`, `skip-slots`, and `block-root`, which previously only supported mainnet.
* **BREAKING CHANGE** Remove the default value of `~/.lighthouse/testnet` from `--testnet-dir`. This may have made sense in previous versions where `lcli` was more testnet focussed, but IMO it is an unnecessary complication and foot-gun today.
## Issue Addressed
#4118
## Proposed Changes
This PR introduces a "progressive balances" cache on the `BeaconState`, which keeps track of the accumulated target attestation balance for the current & previous epochs. The cached values are utilised by fork choice to calculate unrealized justification and finalization (instead of converting epoch participation arrays to balances for each block we receive).
This optimization will be rolled out gradually to allow for more testing. A new `--progressive-balances disabled|checked|strict|fast` flag is introduced to support this:
- `checked`: enabled with checks against participation cache, and falls back to the existing epoch processing calculation if there is a total target attester balance mismatch. There is no performance gain from this as the participation cache still needs to be computed. **This is the default mode for now.**
- `strict`: enabled with checks against participation cache, returns error if there is a mismatch. **Used for testing only**.
- `fast`: enabled with no comparative checks and without computing the participation cache. This mode gives us the performance gains from the optimization. This is still experimental and not currently recommended for production usage, but will become the default mode in a future release.
- `disabled`: disable the usage of progressive cache, and use the existing method for FFG progression calculation. This mode may be useful if we find a bug and want to stop the frequent error logs.
### Tasks
- [x] Initial cache implementation in `BeaconState`
- [x] Perform checks in fork choice to compare the progressive balances cache against results from `ParticipationCache`
- [x] Add CLI flag, and disable the optimization by default
- [x] Testing on Goerli & Benchmarking
- [x] Move caching logic from state processing to the `ProgressiveBalancesCache` (see [this comment](https://github.com/sigp/lighthouse/pull/4362#discussion_r1230877001))
- [x] Add attesting balance metrics

This PR adds the ability to read the Lighthouse logs from the HTTP API for both the BN and the VC.
This is done in such a way to as minimize any kind of performance hit by adding this feature.
The current design creates a tokio broadcast channel and mixes is into a form of slog drain that combines with our main global logger drain, only if the http api is enabled.
The drain gets the logs, checks the log level and drops them if they are below INFO. If they are INFO or higher, it sends them via a broadcast channel only if there are users subscribed to the HTTP API channel. If not, it drops the logs.
If there are more than one subscriber, the channel clones the log records and converts them to json in their independent HTTP API tasks.

## Proposed Changes
Modifies the local testnet scripts to start a network with genesis validators embedded into the genesis state. This allows us to start a local testnet without the need for deploying a deposit contract or depositing validators pre-genesis.
This also enables us to start a local test network at any fork we want without going through fork transitions. Also adds scripts to start multiple geth clients and peer them with each other and peer the geth clients with beacon nodes to start a post merge local testnet.
## Additional info
Adds a new lcli command `mnemonics-validators` that generates validator directories derived from a given mnemonic.
Adds a new `derived-genesis-state` option to the `lcli new-testnet` command to generate a genesis state populated with validators derived from a mnemonic.

## Additional info
Also changes the ethers-rs version used in the execution layer (for the transaction reconstruction) to a newer one. This was necessary to get use the ethers utils for anvil. The fixed execution engine integration tests should catch any potential issues with the payload reconstruction after #3592

## Issue Addressed
There was a [`VecDeque` bug](https://github.com/rust-lang/rust/issues/108453) in some recent versions of the Rust standard library (1.67.0 & 1.67.1) that could cause Lighthouse to panic (reported by `@Sea Monkey` on discord). See full logs below.
The issue was likely introduced in Rust 1.67.0 and [fixed](https://github.com/rust-lang/rust/pull/108475) in 1.68, and we were able to reproduce the panic ourselves using [@michaelsproul's fuzz tests](https://github.com/michaelsproul/lighthouse/blob/fuzz-lru-time-cache/beacon_node/lighthouse_network/src/peer_manager/fuzz.rs#L111) on both Rust 1.67.0 and 1.67.1.
Users that uses our Docker images or binaries are unlikely affected, as our Docker images were built with `1.66`, and latest binaries were built with latest stable (`1.68.2`). It likely impacts user that builds from source using Rust versions 1.67.x.
## Proposed Changes
Bump Rust version (MSRV) to latest stable `1.68.2`.

## Issue Addressed
Add support for ipv6 and dual stack in lighthouse.
## Proposed Changes
From an user perspective, now setting an ipv6 address, optionally configuring the ports should feel exactly the same as using an ipv4 address. If listening over both ipv4 and ipv6 then the user needs to:
- use the `--listen-address` two times (ipv4 and ipv6 addresses)
- `--port6` becomes then required
- `--discovery-port6` can now be used to additionally configure the ipv6 udp port
### Rough list of code changes
- Discovery:
- Table filter and ip mode set to match the listening config.
- Ipv6 address, tcp port and udp port set in the ENR builder
- Reported addresses now check which tcp port to give to libp2p
- LH Network Service:
- Can listen over Ipv6, Ipv4, or both. This uses two sockets. Using mapped addresses is disabled from libp2p and it's the most compatible option.
- NetworkGlobals:
- No longer stores udp port since was not used at all. Instead, stores the Ipv4 and Ipv6 TCP ports.
- NetworkConfig:
- Update names to make it clear that previous udp and tcp ports in ENR were Ipv4
- Add fields to configure Ipv6 udp and tcp ports in the ENR
- Include advertised enr Ipv6 address.
- Add type to model Listening address that's either Ipv4, Ipv6 or both. A listening address includes the ip, udp port and tcp port.
- UPnP:
- Kept only for ipv4
- Cli flags:
- `--listen-addresses` now can take up to two values
- `--port` will apply to ipv4 or ipv6 if only one listening address is given. If two listening addresses are given it will apply only to Ipv4.
- `--port6` New flag required when listening over ipv4 and ipv6 that applies exclusively to Ipv6.
- `--discovery-port` will now apply to ipv4 and ipv6 if only one listening address is given.
- `--discovery-port6` New flag to configure the individual udp port of ipv6 if listening over both ipv4 and ipv6.
- `--enr-udp-port` Updated docs to specify that it only applies to ipv4. This is an old behaviour.
- `--enr-udp6-port` Added to configure the enr udp6 field.
- `--enr-tcp-port` Updated docs to specify that it only applies to ipv4. This is an old behaviour.
- `--enr-tcp6-port` Added to configure the enr tcp6 field.
- `--enr-addresses` now can take two values.
- `--enr-match` updated behaviour.
- Common:
- rename `unused_port` functions to specify that they are over ipv4.
- add functions to get unused ports over ipv6.
- Testing binaries
- Updated code to reflect network config changes and unused_port changes.
## Additional Info
TODOs:
- use two sockets in discovery. I'll get back to this and it's on https://github.com/sigp/discv5/pull/160
- lcli allow listening over two sockets in generate_bootnodes_enr
- add at least one smoke flag for ipv6 (I have tested this and works for me)
- update the book

- in new branch off unstable with the squashed commit create a `git revert HEAD` commit
- merge that new branch onto 4844 with `--strategy ours`
- compare local 4844 to remote 4844 and make sure the diff is empty

## Proposed Changes
Decouple the stdout and logfile formats by adding the `--logfile-format` CLI flag.
This behaves identically to the existing `--log-format` flag, but instead will only affect the logs written to the logfile.
The `--log-format` flag will no longer have any effect on the contents of the logfile.
## Additional Info
This avoids being a breaking change by causing `logfile-format` to default to the value of `--log-format` if it is not provided.
This means that users who were previously relying on being able to use a JSON formatted logfile will be able to continue to use `--log-format JSON`.
Users who want to use JSON on stdout and default logs in the logfile, will need to pass the following flags: `--log-format JSON --logfile-format DEFAULT`

## 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
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.

## 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.

With this change the proposer index should be calculated only once for each block, and then plumbed through to every place it is required.
## Additional Info
In future I hope to add more data to the consensus context that is cached on a per-epoch basis, like the effective balances of validators and the base rewards.
There are some other changes to remove indexing in tests that were also useful for `tree-states` (the `tree-states` types don't implement `Index`).

## Proposed Changes
With https://github.com/sigp/lighthouse/pull/3214 we made it such that you can either have 1 auth endpoint or multiple non auth endpoints. Now that we are post merge on all networks (testnets and mainnet), we cannot progress a chain without a dedicated auth execution layer connection so there is no point in having a non-auth eth1-endpoint for syncing deposit cache.
This code removes all fallback related code in the eth1 service. We still keep the single non-auth endpoint since it's useful for testing.

This removes all eth1 fallback related metrics that were relevant for the monitoring service, so we might need to change the api upstream.
## Issue Addressed
The release CI is currently broken due to the addition of the `protoc` dependency. Here's a failure of the release flow running on my fork: https://github.com/michaelsproul/lighthouse/actions/runs/3155541478/jobs/5134317334
## Proposed Changes
- Install `protoc` on Windows and Mac so that it's available for `cargo install`.
- Install an x86_64 binary in the Cross image for the aarch64 platform: we need a binary that runs on the host, _not_ on the target.
- Fix `macos` local testnet CI by using the Github API key to dodge rate limiting (this issue: https://github.com/actions/runner-images/issues/602).
