#3031
## Proposed Changes
Updates the following API endpoints to conform with https://github.com/ethereum/beacon-APIs/pull/190 and https://github.com/ethereum/beacon-APIs/pull/196
- [x] `beacon/states/{state_id}/root`
- [x] `beacon/states/{state_id}/fork`
- [x] `beacon/states/{state_id}/finality_checkpoints`
- [x] `beacon/states/{state_id}/validators`
- [x] `beacon/states/{state_id}/validators/{validator_id}`
- [x] `beacon/states/{state_id}/validator_balances`
- [x] `beacon/states/{state_id}/committees`
- [x] `beacon/states/{state_id}/sync_committees`
- [x] `beacon/headers`
- [x] `beacon/headers/{block_id}`
- [x] `beacon/blocks/{block_id}`
- [x] `beacon/blocks/{block_id}/root`
- [x] `beacon/blocks/{block_id}/attestations`
- [x] `debug/beacon/states/{state_id}`
- [x] `debug/beacon/heads`
- [x] `validator/duties/attester/{epoch}`
- [x] `validator/duties/proposer/{epoch}`
- [x] `validator/duties/sync/{epoch}`
Updates the following Server-Sent Events:
- [x] `events?topics=head`
- [x] `events?topics=block`
- [x] `events?topics=finalized_checkpoint`
- [x] `events?topics=chain_reorg`
## Backwards Incompatible
There is a very minor breaking change with the way the API now handles requests to `beacon/blocks/{block_id}/root` and `beacon/states/{state_id}/root` when `block_id` or `state_id` is the `Root` variant of `BlockId` and `StateId` respectively.
Previously a request to a non-existent root would simply echo the root back to the requester:
```
curl "http://localhost:5052/eth/v1/beacon/states/0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/root"
{"data":{"root":"0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"}}
```
Now it will return a `404`:
```
curl "http://localhost:5052/eth/v1/beacon/blocks/0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa/root"
{"code":404,"message":"NOT_FOUND: beacon block with root 0xaaaa…aaaa","stacktraces":[]}
```
In addition to this is the block root `0x0000000000000000000000000000000000000000000000000000000000000000` previously would return the genesis block. It will now return a `404`:
```
curl "http://localhost:5052/eth/v1/beacon/blocks/0x0000000000000000000000000000000000000000000000000000000000000000"
{"code":404,"message":"NOT_FOUND: beacon block with root 0x0000…0000","stacktraces":[]}
```
## Additional Info
- `execution_optimistic` is always set, and will return `false` pre-Bellatrix. I am also open to the idea of doing something like `#[serde(skip_serializing_if = "Option::is_none")]`.
- The value of `execution_optimistic` is set to `false` where possible. Any computation that is reliant on the `head` will simply use the `ExecutionStatus` of the head (unless the head block is pre-Bellatrix).

## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/3189.
## Proposed Changes
- Always supply the justified block hash as the `safe_block_hash` when calling `forkchoiceUpdated` on the execution engine.
- Refactor the `get_payload` routine to use the new `ForkchoiceUpdateParameters` struct rather than just the `finalized_block_hash`. I think this is a nice simplification and that the old way of computing the `finalized_block_hash` was unnecessary, but if anyone sees reason to keep that approach LMK.
## Issue Addressed
- Resolves#3338
## Proposed Changes
This PR adds a new `--network goerli` flag that reuses the [Prater network configs](https://github.com/sigp/lighthouse/tree/stable/common/eth2_network_config/built_in_network_configs/prater).
As you'll see in #3338, there are several approaches to the problem of the Goerli/Prater alias. This approach achieves:
1. No duplication of the genesis state between Goerli and Prater.
- Upside: the genesis state for Prater is ~17mb, duplication would increase the size of the binary by that much.
2. When the user supplies `--network goerli`, they will get a datadir in `~/.lighthouse/goerli`.
- Upside: our docs stay correct when they declare a datadir is located at `~/.lighthouse/{network}`
- Downside: switching from `--network prater` to `--network goerli` will require some manual migration.
3. When using `--network goerli`, the [`config/spec`](https://ethereum.github.io/beacon-APIs/#/Config/getSpec) endpoint will return a [`CONFIG_NAME`](02a2b71d64/configs/mainnet.yaml (L11)) of "prater".
- Upside: VC running `--network prater` will still think it's on the same network as one using `--network goerli`.
- Downside: potentially confusing.
#3348 achieves the same goal as this PR with a different approach and set of trade-offs.
## Additional Info
### Notes for reviewers:
In e4896c2682 you'll see that I remove the `$name_str` by just using `stringify!($name_ident)` instead. This is a simplification that should have have been there in the first place.
Then, in 90b5e22fca I reclaim that second parameter with a new purpose; to specify the directory from which to load configs.

## Proposed Changes
There are a number of cases during block processing where we might get an `ExecutionPayloadError` but we shouldn't penalize peers. We were forgetting to enumerate all of the non-penalizing errors in every single match statement where we are making that decision. I created a function to make it explicit when we should and should not penalize peers and I used that function in all places where this logic is needed. This way we won't make the same mistake if we add another variant of `ExecutionPayloadError` in the future.

## Issue Addressed
#3302
## Proposed Changes
Move the `reqwest::Client` from being initialized per-validator, to being initialized per distinct Web3Signer.
This is done by placing the `Client` into a `HashMap` keyed by the definition of the Web3Signer as specified by the `ValidatorDefintion`. This will allow multiple Web3Signers to be used with a single VC and also maintains backwards compatibility.
## Additional Info
This was done to reduce the memory used by the VC when connecting to a Web3Signer.
I set up a local testnet using [a custom script](https://github.com/macladson/lighthouse/tree/web3signer-local-test/scripts/local_testnet_web3signer) and ran a VC with 200 validator keys:
VC with Web3Signer:
- `unstable`: ~200MB
- With fix: ~50MB
VC with Local Signer:
- `unstable`: ~35MB
- With fix: ~35MB
> I'm seeing some fragmentation with the VC using the Web3Signer, but not when using a local signer (this is most likely due to making lots of http requests and dealing with lots of JSON objects). I tested the above using `MALLOC_ARENA_MAX=1` to try to reduce the fragmentation. Without it, the values are around +50MB for both `unstable` and the fix.

Make simulator merge compatible. Adds a `--post_merge` flag to the eth1 simulator that enables a ttd and simulates the merge transition. Uses the `MockServer` in the execution layer test utils to simulate a dummy execution node.
Adds the merge transition simulation to CI.
## Issue Addressed

## Proposed Changes
Sends transactions to the EE before requesting for a payload in the `execution_integration_tests`. Made some changes to the integration tests in order to be able to sign and publish transactions to the EE:
1. `genesis.json` for both geth and nethermind was modified to include pre-funded accounts that we know private keys for
2. Using the unauthenticated port again in order to make `eth_sendTransaction` and calls from the `personal` namespace to import keys
Also added a `fcu` call with `PayloadAttributes` before calling `getPayload` in order to give EEs sufficient time to pack transactions into the payload.
Improves some of the functionality around single and parent block lookup.
Gives extra information about whether failures for lookups are related to processing or downloading.
This is entirely untested.

Web3signer validators can't produce post-Bellatrix blocks.
## Proposed Changes
Add support for Bellatrix to web3signer validators.
## Additional Info
I am running validators with this code on Ropsten, but it may be a while for them to get a proposal.
## Proposed Changes
Adds some improvements I found when playing around with local testnets in #3335:
- When trying to kill processes, do not exit on a failure. (If a node fails to start due to a bug, the PID associated with it no longer exists. When trying to tear down the testnets, an error will be raised when it tries that PID and then will not try any PIDs following it. This change means it will continue and tear down the rest of the network.
- When starting the testnet, set `ulimit` to a high number. This allows the VCs to import 1000s of validators without running into limitations.

## Proposed Changes
After some discussion in Discord with @mkalinin it was raised that it was not the intention of the engine API to have CLs validate the `latest_valid_hash` (LVH) and all ancestors.
Whilst I believe the engine API is being updated such that the LVH *must* identify a valid hash or be set to some junk value, I'm not confident that we can rely upon the LVH as being valid (at least for now) due to the confusion surrounding it.
Being able to validate blocks via the LVH is a relatively minor optimisation; if the LVH value ends up becoming our head we'll send an fcU and get the VALID status there.
Falsely marking a block as valid has serious consequences and since it's a minor optimisation to use LVH I think that we don't take the risk.
For clarity, we will still *invalidate* the *descendants* of the LVH, we just wont *validate* the *ancestors*.

## Proposed Changes
Continues from PRs by @divagant-martian to gradually remove EL redundancy (see #3284, #3257).
This PR achieves:
- Removes the `broadcast` and `first_success` methods. The functional impact is that every request to the EE will always be tried immediately, regardless of the cached `EngineState` (this resolves#3176). Previously we would check the engine state before issuing requests, this doesn't make sense in a single-EE world; there's only one EE so we might as well try it for every request.
- Runs the upcheck/watchdog routine once per slot rather than thrice. When we had multiple EEs frequent polling was useful to try and detect when the primary EE had come back online and we could switch to it. That's not as relevant now.
- Always creates logs in the `Engines::upcheck` function. Previously we would mute some logs since they could get really noisy when one EE was down but others were functioning fine. Now we only have one EE and are upcheck-ing it less, it makes sense to always produce logs.
This PR purposefully does not achieve:
- Updating all occurances of "engines" to "engine". I'm trying to keep the diff small and manageable. We can come back for this.

## Proposed Changes
Add a timeout for the sync committee contributions at 1/4 the slot length such that we may be able to try backup beacon nodes in the case of contribution post failure.
## Additional Info
1/4 slot length seemed standard for the timeouts, but may want to decrease this to 1/2.
I did not find any timeout related / sync committee related tests, so there are no tests. Happy to write some with a bit of guidance.
## Issue Addressed
* #3173
## Proposed Changes
Moved all `fee_recipient_file` related logic inside the `ValidatorStore` as it makes more sense to have this all together there. I tested this with the validators I have on `mainnet-shadow-fork-5` and everything appeared to work well. Only technicality is that I can't get the method to return `401` when the authorization header is not specified (it returns `400` instead). Fixing this is probably quite difficult given that none of `warp`'s rejections have code `401`.. I don't really think this matters too much though as long as it fails.
## Issue Addressed
Follow up to https://github.com/sigp/lighthouse/pull/3290 that fixes a caching bug
## Proposed Changes
Build the committee cache for the new `POST /lighthouse/analysis/block_rewards` API. Due to an unusual quirk of the total active balance cache the API endpoint would sometimes fail after loading a state from disk which had a current epoch cache _but not_ a total active balance cache. This PR adds calls to build the caches immediately before they're required, and has been running smoothly with `blockdreamer` the last few days.
## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/3270
## Proposed Changes
Optimize the calculation of historic beacon committees in the HTTP API.
This is achieved by allowing committee caches to be constructed for historic epochs, and constructing these committee caches on the fly in the API. This is much faster than reconstructing the state at the requested epoch, which usually takes upwards of 20s, and sometimes minutes with SPRP=8192. The depth of the `randao_mixes` array allows us to look back 64K epochs/0.8 years from a single state, which is pretty awesome!
We always use the `state_id` provided by the caller, but will return a nice 400 error if the epoch requested is out of range for the state requested, e.g.
```bash
# Prater
curl "http://localhost:5052/eth/v1/beacon/states/3170304/committees?epoch=33538"
```
```json
{"code":400,"message":"BAD_REQUEST: epoch out of bounds, try state at slot 1081344","stacktraces":[]}
```
Queries will be fastest when aligned to `slot % SPRP == 0`, so the hint suggests a slot that is 0 mod 8192.
## Issue Addressed
Currently the execution-engine-integration test uses latest master for nethermind and geth, and right now the test fails using the latest unreleased commits.
## Proposed Changes
Fix the nethermind and geth revisions the test uses to the latest tag in each repo. This way we are not continuously testing unreleased code, which might even get reverted, and reduce the failures only to releases in each one.
Also improve error handling of the commands used to manage the git repos.

## Overview
This rather extensive PR achieves two primary goals:
1. Uses the finalized/justified checkpoints of fork choice (FC), rather than that of the head state.
2. Refactors fork choice, block production and block processing to `async` functions.
Additionally, it achieves:
- Concurrent forkchoice updates to the EL and cache pruning after a new head is selected.
- Concurrent "block packing" (attestations, etc) and execution payload retrieval during block production.
- Concurrent per-block-processing and execution payload verification during block processing.
- The `Arc`-ification of `SignedBeaconBlock` during block processing (it's never mutated, so why not?):
- I had to do this to deal with sending blocks into spawned tasks.
- Previously we were cloning the beacon block at least 2 times during each block processing, these clones are either removed or turned into cheaper `Arc` clones.
- We were also `Box`-ing and un-`Box`-ing beacon blocks as they moved throughout the networking crate. This is not a big deal, but it's nice to avoid shifting things between the stack and heap.
- Avoids cloning *all the blocks* in *every chain segment* during sync.
- It also has the potential to clean up our code where we need to pass an *owned* block around so we can send it back in the case of an error (I didn't do much of this, my PR is already big enough 😅)
- The `BeaconChain::HeadSafetyStatus` struct was removed. It was an old relic from prior merge specs.
For motivation for this change, see https://github.com/sigp/lighthouse/pull/3244#issuecomment-1160963273
## Changes to `canonical_head` and `fork_choice`
Previously, the `BeaconChain` had two separate fields:
```
canonical_head: RwLock<Snapshot>,
fork_choice: RwLock<BeaconForkChoice>
```
Now, we have grouped these values under a single struct:
```
canonical_head: CanonicalHead {
cached_head: RwLock<Arc<Snapshot>>,
fork_choice: RwLock<BeaconForkChoice>
}
```
Apart from ergonomics, the only *actual* change here is wrapping the canonical head snapshot in an `Arc`. This means that we no longer need to hold the `cached_head` (`canonical_head`, in old terms) lock when we want to pull some values from it. This was done to avoid deadlock risks by preventing functions from acquiring (and holding) the `cached_head` and `fork_choice` locks simultaneously.
## Breaking Changes
### The `state` (root) field in the `finalized_checkpoint` SSE event
Consider the scenario where epoch `n` is just finalized, but `start_slot(n)` is skipped. There are two state roots we might in the `finalized_checkpoint` SSE event:
1. The state root of the finalized block, which is `get_block(finalized_checkpoint.root).state_root`.
4. The state root at slot of `start_slot(n)`, which would be the state from (1), but "skipped forward" through any skip slots.
Previously, Lighthouse would choose (2). However, we can see that when [Teku generates that event](de2b2801c8/data/beaconrestapi/src/main/java/tech/pegasys/teku/beaconrestapi/handlers/v1/events/EventSubscriptionManager.java (L171-L182)) it uses [`getStateRootFromBlockRoot`](de2b2801c8/data/provider/src/main/java/tech/pegasys/teku/api/ChainDataProvider.java (L336-L341)) which uses (1).
I have switched Lighthouse from (2) to (1). I think it's a somewhat arbitrary choice between the two, where (1) is easier to compute and is consistent with Teku.
## Notes for Reviewers
I've renamed `BeaconChain::fork_choice` to `BeaconChain::recompute_head`. Doing this helped ensure I broke all previous uses of fork choice and I also find it more descriptive. It describes an action and can't be confused with trying to get a reference to the `ForkChoice` struct.
I've changed the ordering of SSE events when a block is received. It used to be `[block, finalized, head]` and now it's `[block, head, finalized]`. It was easier this way and I don't think we were making any promises about SSE event ordering so it's not "breaking".
I've made it so fork choice will run when it's first constructed. I did this because I wanted to have a cached version of the last call to `get_head`. Ensuring `get_head` has been run *at least once* means that the cached values doesn't need to wrapped in an `Option`. This was fairly simple, it just involved passing a `slot` to the constructor so it knows *when* it's being run. When loading a fork choice from the store and a slot clock isn't handy I've just used the `slot` that was saved in the `fork_choice_store`. That seems like it would be a faithful representation of the slot when we saved it.
I added the `genesis_time: u64` to the `BeaconChain`. It's small, constant and nice to have around.
Since we're using FC for the fin/just checkpoints, we no longer get the `0x00..00` roots at genesis. You can see I had to remove a work-around in `ef-tests` here: b56be3bc2. I can't find any reason why this would be an issue, if anything I think it'll be better since the genesis-alias has caught us out a few times (0x00..00 isn't actually a real root). Edit: I did find a case where the `network` expected the 0x00..00 alias and patched it here: 3f26ac3e2.
You'll notice a lot of changes in tests. Generally, tests should be functionally equivalent. Here are the things creating the most diff-noise in tests:
- Changing tests to be `tokio::async` tests.
- Adding `.await` to fork choice, block processing and block production functions.
- Refactor of the `canonical_head` "API" provided by the `BeaconChain`. E.g., `chain.canonical_head.cached_head()` instead of `chain.canonical_head.read()`.
- Wrapping `SignedBeaconBlock` in an `Arc`.
- In the `beacon_chain/tests/block_verification`, we can't use the `lazy_static` `CHAIN_SEGMENT` variable anymore since it's generated with an async function. We just generate it in each test, not so efficient but hopefully insignificant.
I had to disable `rayon` concurrent tests in the `fork_choice` tests. This is because the use of `rayon` and `block_on` was causing a panic.

## Issue Addressed
Lays the groundwork for builder API changes by implementing the beacon-API's new `register_validator` endpoint
## Proposed Changes
- Add a routine in the VC that runs on startup (re-try until success), once per epoch or whenever `suggested_fee_recipient` is updated, signing `ValidatorRegistrationData` and sending it to the BN.
- TODO: `gas_limit` config options https://github.com/ethereum/builder-specs/issues/17
- BN only sends VC registration data to builders on demand, but VC registration data *does update* the BN's prepare proposer cache and send an updated fcU to a local EE. This is necessary for fee recipient consistency between the blinded and full block flow in the event of fallback. Having the BN only send registration data to builders on demand gives feedback directly to the VC about relay status. Also, since the BN has no ability to sign these messages anyways (so couldn't refresh them if it wanted), and validator registration is independent of the BN head, I think this approach makes sense.
- Adds upcoming consensus spec changes for this PR https://github.com/ethereum/consensus-specs/pull/2884
- I initially applied the bit mask based on a configured application domain.. but I ended up just hard coding it here instead because that's how it's spec'd in the builder repo.
- Should application mask appear in the api?

## Issue Addressed
Resolves#3069
## Proposed Changes
Unify the `eth1-endpoints` and `execution-endpoints` flags in a backwards compatible way as described in https://github.com/sigp/lighthouse/issues/3069#issuecomment-1134219221
Users have 2 options:
1. Use multiple non auth execution endpoints for deposit processing pre-merge
2. Use a single jwt authenticated execution endpoint for both execution layer and deposit processing post merge
Related https://github.com/sigp/lighthouse/issues/3118
To enable jwt authenticated deposit processing, this PR removes the calls to `net_version` as the `net` namespace is not exposed in the auth server in execution clients.
Moving away from using `networkId` is a good step in my opinion as it doesn't provide us with any added guarantees over `chainId`. See https://github.com/ethereum/consensus-specs/issues/2163 and https://github.com/sigp/lighthouse/issues/2115

## Proposed Changes
Add a new HTTP endpoint `POST /lighthouse/analysis/block_rewards` which takes a vec of `BeaconBlock`s as input and outputs the `BlockReward`s for them.
Augment the `BlockReward` struct with the attestation data for attestations in the block, which simplifies access to this information from blockprint. Using attestation data I've been able to make blockprint up to 95% accurate across Prysm/Lighthouse/Teku/Nimbus. I hope to go even higher using a bunch of synthetic blocks produced for Prysm/Nimbus/Lodestar, which are underrepresented in the current training data.
## Proposed Changes
Update `Cross.toml` for the recently released Cross v0.2.2. This allows us to remove the dependency on my fork of the Cross Docker image, which was a maintenance burden and prone to bit-rot. This PR puts us back in sync with upstream Cross.
## Additional Info
Due to some bindgen errors on the default Cross images we seemingly need a full `clang-3.9` install. The `libclang-3.9-dev` package was found to be insufficient due to `stdarg.h` being missing.
In order to continue building locally all Lighthouse devs should update their local cross version with `cargo install cross`.
## Issue Addressed
Fixes#1864 and a bunch of other closed but unresolved issues.
## Proposed Changes
Allows the deposit caching to recover from `NonConsecutive` deposit errors by resetting the last processed block to the last valid deposit's block number. Still not sure of the underlying cause of this error, but this should recover the cache so we don't need `--eth1-purge-cache` anymore 🎉
A huge thanks to @one-three-three-seven for reproducing the error and providing the data that helped testing out the fix 🙌
Still needs a few more tests.
## Proposed Changes
Expand the set of paths tracked by the HTTP API metrics to include all paths hit by the validator client.
These paths were only partially updated for Altair, so we were missing some of the sync committee and v2 APIs.

Deprecates the step parameter in the blocks by range request
## Proposed Changes
- Modifies the BlocksByRangeRequest type to remove the step parameter and everywhere we took it into account before
- Adds a new type to still handle coding and decoding of requests that use the parameter
## Additional Info
I went with a deprecation over the type itself so that requests received outside `lighthouse_network` don't even need to deal with this parameter. After the deprecation period just removing the Old blocks by range request should be straightforward
