## Proposed Changes
Shifts the gossipsub message id to use the first 8 bytes of the SHA256 hash of the gossipsub message data field.
## Additional Info
We should merge this in once the spec has been decided on. It will cause issues with gossipsub scoring and gossipsub propagation rates (as we won't receive IWANT) messages from clients that also haven't made this update.

#1590
## Proposed Changes
This is a temporary workaround that prevents finalized chain sync from swapping chains. I'm merging this in now until the full solution is ready.
## Issue Addressed
Malicious users could request very large block ranges, more than we expect. Although technically legal, we are now quadraticaly weighting large step sizes in the filter. Therefore users may request large skips, but not a large number of blocks, to prevent requests forcing us to do long chain lookups.
## Proposed Changes
Weight the step parameter in the RPC filter and prevent any overflows that effect us in the step parameter.

## Issue Addressed
Partly addresses #1547
## Proposed Changes
This fix addresses the missing attestations at slot 0 of an epoch (also sometimes slot 1 when slot 0 was skipped).
There are 2 cases:
1. BN receives the block for the attestation slot after 4 seconds (1/3rd of the slot).
2. No block is proposed for this slot.
In both cases, when we produce the attestation, we pass the head state to the
`produce_unaggregated_attestation_for_block` function here
9833eca024/beacon_node/beacon_chain/src/beacon_chain.rs (L845-L850)
Since we don't advance the state in this function, we set `attestation.data.source = state.current_justified_checkpoint` which is atleast 2 epochs lower than current_epoch(wall clock epoch).
This attestation is invalid and cannot be included in a block because of this assert from the spec:
```python
if data.target.epoch == get_current_epoch(state):
assert data.source == state.current_justified_checkpoint
state.current_epoch_attestations.append(pending_attestation)
```
https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/beacon-chain.md#attestations
This PR changes the `produce_unaggregated_attestation_for_block` function to ensure that it advances the state before producing the attestation at the new epoch.
Running this on my node, have missed 0 attestations across all 8 of my validators in a 100 epoch period 🎉
To compare, I was missing ~14 attestations across all 8 validators in the same 100 epoch period before the fix.
Will report missed attestations if any after running for another 100 epochs tomorrow.

## Proposed Changes
* updates the libp2p dependency

* report not just valid messages but also invalid and distinguish between `IGNORE`d messages and `REJECT`ed messages
Co-authored-by: Age Manning <Age@AgeManning.com>
The PR:
* Adds the ability to generate a crucial test scenario that isn't possible with `BeaconChainHarness` (i.e. two blocks occupying the same slot; previously forks necessitated skipping slots):
* New testing API: Instead of repeatedly calling add_block(), you generate a sorted `Vec<Slot>` and leave it up to the framework to generate blocks at those slots.
* Jumping backwards to an earlier epoch is a hard error, so that tests necessarily generate blocks in a epoch-by-epoch manner.
* Configures the test logger so that output is printed on the console in case a test fails. The logger also plays well with `--nocapture`, contrary to the existing testing framework
* Rewrites existing fork pruning tests to use the new API
* Adds a tests that triggers finalization at a non epoch boundary slot
* Renamed `BeaconChainYoke` to `BeaconChainTestingRig` because the former has been too confusing
* Fixed multiple tests (e.g. `block_production_different_shuffling_long`, `delete_blocks_and_states`, `shuffling_compatible_simple_fork`) that relied on a weird (and accidental) feature of the old `BeaconChainHarness` that attestations aren't produced for epochs earlier than the current one, thus masking potential bugs in test cases.

## Issue Addressed
Closes#1488
## Proposed Changes
* Prevent the pruning algorithm from over-eagerly deleting states at skipped slots when they are shared with the canonical chain.
* Add `debug` logging to the pruning algorithm so we have so better chance of debugging future issues from logs.
* Modify the handling of the "finalized state" in the beacon chain, so that it's always the state at the first slot of the finalized epoch (previously it was the state at the finalized block). This gives database pruning a clearer and cleaner view of things, and will marginally impact the pruning of the op pool, observed proposers, etc (in ways that are safe as far as I can tell).
* Remove duplicated `RevertedFinalizedEpoch` check from `after_finalization`
* Delete useless and unused `max_finality_distance`
* Add tests that exercise pruning with shared states at skip slots
* Delete unnecessary `block_strategy` argument from `add_blocks` and friends in the test harness (will likely conflict with #1380 slightly, sorry @adaszko -- but we can fix that)
* Bonus: add a `BeaconChain::with_head` method. I didn't end up needing it, but it turned out quite nice, so I figured we could keep it?
## Additional Info

## Proposed Changes
Shift practically all HTTP endpoint handlers to the blocking executor (some very light tasks are left on the core executor).
## Additional Info
This PR covers the `rest_api` which will soon be refactored to suit the standard API. As such, I've cut a few corners and left some existing issues open in this patch. What I have done here should leave the API in state that is not necessary *exactly* the same, but good enough for us to run validators with. Specifically, the number of blocking workers that can be spawned is unbounded and I have not implemented a queue; this will need to be fixed when we implement the standard API.
## Issue Addressed
#1378
## Proposed Changes
Boot node reuses code from beacon_node to initialize network config. This also enables using the network directory to store/load the enr and the private key.
## Additional Info
Note that before this PR the port cli arguments were off (the argument was named `enr-port` but used as `boot-node-enr-port`).
Therefore as port always the cli port argument was used (for both enr and listening). Now the enr-port argument can be used to overwrite the listening port as the public port others should connect to.
Last but not least note, that this restructuring reuses `ethlibp2p::NetworkConfig` that has many more options than the ones used in the boot node. For example the network config has an own `discv5_config` field that gets never used in the boot node and instead another `Discv5Config` gets created later in the boot node process.

Refactor attestation service to send out requests to find peers for subnets as soon as we get attestation duties.

## Description
This PR improves some logging for the end-user.
It downgrades some warning logs and removes the slots per second sync speed if we are syncing and the speed is 0. This is likely because we are syncing from a finalised checkpoint and the head doesn't change.
## Issue Addressed
NA
## Proposed Changes

## Description
There can be many head chains queued up to complete. Currently we try and process all of these to completion before we consider the node synced.
In a chaotic network, there can be many of these and processing them to completion can be very expensive and slow. This PR removes any non-syncing head chains from the queue, and re-status's the peers. If, after we have synced to head on one chain, there is still a valid head chain to download, it will be re-established once the status has been returned.
This should assist with getting nodes to sync on medalla faster.
## Overview
There are forked chains which get referenced by blocks and attestations on a network. Typically if these chains are very long, we stop looking up the chain and downvote the peer. In extreme circumstances, many peers are on many chains, the chains can be very deep and become time consuming performing lookups.
This PR adds a cache to known failed chain lookups. This prevents us from starting a parent-lookup (or stopping one half way through) if we have attempted the chain lookup in the past.
## Description
Currently lighthouse load-balances across peers a single finalized chain. The chain is selected via the most peers. Once synced to the latest finalized epoch Lighthouse creates chains amongst its peers and syncs them all in parallel amongst each peer (grouped by their current head block).
This is typically fast and relatively efficient under normal operations. However if the chain has not finalized in a long time, the head chains can grow quite long. Peer's head chains will update every slot as new blocks are added to the head. Syncing all head chains in parallel is a bottleneck and highly inefficient in block duplication leads to RPC timeouts when attempting to handle all new heads chains at once.
This PR limits the parallelism of head syncing chains to 2. We now sync at most two head chains at a time. This allows for the possiblity of sync progressing alongside a peer being slow and holding up one chain via RPC timeouts.
The changes are somewhat simple but should solve two issues:
- When quickly changing between chains once and a second time back again, batchIds would collide and cause havoc.
- If we got an out of range response from a peer, sync would remain in syncing but without advancing
Changes:
- remove the batch id. Identify each batch (inside a chain) by its starting epoch. Target epochs for downloading and processing now advance by EPOCHS_PER_BATCH
- for the same reason, move the "to_be_downloaded_id" to be an epoch
- remove a sneaky line that dropped an out of range batch without downloading it
- bonus: put the chain_id in the log given to the chain. This is why explicitly logging the chain_id is removed
## Proposed Changes
To mitigate the impact of minority forks on RAM and disk usage, this change rejects blocks whose parent lies more than 320 slots (10 epochs, ~1 hour) in the past. The behaviour is configurable via `lighthouse bn --max-skip-slots N`, and can be turned off entirely using `--max-skip-slots none`.

## Proposed Changes

- Don't clone caches on intermediate epoch-boundary states during block processing.
- Reject blocks that are known to fork choice earlier during gossip processing, instead of waiting until after state has been loaded (this only happens in edge-case).
- Avoid multiple re-allocations by creating a "forced" exact size iterator.

## Discovery v5 update
In this update we remove the openssl dependency in favour of rust-crypto.
The update also removes a series of unnecessary async functions which may improve some of the issues we have been experiencing.
## Issue Addressed
- Resolves#1451
## Proposed Changes
- Restricts the `contains_block` and `contains_block` so they only indicate a block is present if it descends from the finalized root. This helps to ensure that fork choice never points to a block that has been pruned from the database.
- Resolves#1451
- Before importing a block, double-check that its parent is known and a descendant of the finalized root.
- Split a big, monolithic block verification test into smaller tests.
## Additional Notes
I suspect there would be a craftier way to do the `is_descendant_of_finalized` check, but we're a bit tight on time now and we can optimize later if it starts showing in benches.

Introduces the `GossipProcessor`, a multi-threaded (multi-tasked?), non-blocking processor for some messages from the network which require verification and import into the `BeaconChain`.

## Proposed Changes
Adds support for using the [`cross`](https://github.com/rust-embedded/cross) project to produce cross-compiled binaries using Docker images.
Provides quite clean and simple cross-compiles cause all the complexity is hidden in Dockerfiles. It does require you to be in the `docker` group though.
## Details
- Adds shortcut commands to `Makefile`
- Ensures `reqwest` and `discv5` use vendored openssl libs (i.e., static not shared).
- Switches to a [commit](284f705964) of blst that has a renamed C function to avoid a collision with openssl (upstream issue: https://github.com/supranational/blst/issues/21).
- Updates `ring` to the latest satisfiable version, since an earlier version was causing issues with `cross`.
- Off-topic, but adds extra message about Windows support as suggested by Discord user.
## Additional Info
- ~~Blocked on #1495~~
- There are no tests in CI for this yet for a few reasons:
- I'm hesitant to add more long-running tasks.
- Short-term bitrot should be avoided since we'll use it each release.
- In the long term I think it would be good to automate binary creation on a release.
- I observed the binaries increase in size from 50mb to 52mb after these changes.
limit simultaneous outgoing connections attempts to a reasonable top as an extra layer of protection
also shift the keep alive logic of the rpc handler to avoid needing to update it by hand. I think In rare cases this could make shutting down a connection a bit faster.

Upgrades the log to a critical if a listener fails. We are able to listen on many interfaces so a single instance is not critical. We should however gracefully shutdown the client if we have no listeners, although the client can still function solely on outgoing connections.
For now a critical is raised and I leave #1494 for more sophisticated handling of this.
This also updates discv5 to handle errors of binding to a UDP socket such that lighthouse is now able to handle them.
## Issue Addressed
Some nodes not following head, high CPU usage and HTTP API delays
## Proposed Changes
Patches gossipsub. Gossipsub was using an `lru_time_cache` to check for duplicates. This contained an `O(N)` lookup for every gossipsub message to update the time cache. This was causing high cpu usage and blocking network threads.
This PR introduces a custom cache without `O(N)` inserts.
This also adds built in safety mechanisms to prevent gossipsub from excessively retrying connections upon failure. A maximum limit is set after which we disconnect from the node from too many failed substream connections.
## Issue Addressed
Peers that connected after the peer limit may remain connected in some circumstances.

## Proposed Changes
- Moves the git-based versioning we were doing into the `lighthouse_version` crate in `common`.
- Removes the `beacon_node/version` crate, replacing it with `lighthouse_version`.
- Bumps the version to `v0.2.0`.
## Additional Info
There are now two types of version string:
1. `const VERSION: &str = Lighthouse/v0.2.0-1419501f2+`
1. `version_with_platform() = Lighthouse/v0.2.0-1419501f2+/x86_64-linux`
(1) is handy cause it's a `const` and shorter. (2) has platform info so it's more useful. Note that the plus-sign (`+`) indicates the the git commit is dirty (it used to be `(modified)` but I had to shorten it to fit into graffiti).
These version strings are now included on:
- `lighthouse --version`
- `lcli --version`
- `curl localhost:5052/node/version`
- p2p messages when we communicate our version
You can update the version by changing this constant (version is not related to a `Cargo.toml`):
b9ad7102d5/common/lighthouse_version/src/lib.rs (L4-L15)
## Issue Addressed
Sync was breaking occasionally. The root cause appears to be identify crashing as events we being sent to the protocol after nodes were banned. Have not been able to reproduce sync issues since this update.
## Proposed Changes
Only send messages to sub-behaviour protocols if the peer manager thinks the peer is connected. All other messages are dropped.
## Issue Addressed
The most recent gossipsub update had an issue where some privacy settings lead to not sending a sequence number with the message. Although Lighthouse treats these as valid (based on current configuration) other clients may not.
This corrects gossipsub to send sequence numbers where expected and based on the configuration settings.
## Issue Addressed
#1056
## Proposed Changes
- Add a rate limiter to the RPC behaviour. This also means the rate limiting occurs just before the door to the application level, so the number of connections a peer opens does not affect this (this would happen in the future if put on the handler)
- The algorithm used is the leaky bucket as a meter / token bucket implemented the GCRA way
- Each protocol has its own limit. Due to the way the algorithm works, the "small" protocols have a hard limit, while bbrange and bbroot allow [burstiness](https://www.wikiwand.com/en/Burstiness). This is so that a peer can't request hundreds of individual requests expecting only one block in a short period of time, it also allows a peer to send two half size requests instead of one with max if they want to without getting limited, and.. it also allows a peer to request a batch of the maximum size and then send _appropriately spaced_ requests of really small sizes. From what I've seen in sync this is plausible when reaching the target slot.

#1388 partially (eth2_libp2p & network)
## Proposed Changes
TLDR at the end
- *Complex types* are 3 on the handlers/Behaviours but the types are `Poll<ComplexType>` where `ComplexType` comes from the traits of libp2p. Those, I don't thing are worth an alias. A couple more were from using tokio combinators and were removed writing things the async way and using [`BoxFuture`](https://docs.rs/futures/0.3.5/futures/future/type.BoxFuture.html)
- The *cognitive complexity*.. I tried to address those before (they come from the poll functions too) and tbh they are cognitively simpler to understand the way they are now. Moving separate parts to functions doesn't add much since that code is not repeated and they all do early returns. If moved those returns would now need to be wrapped in an Option, probably, and checked to be returned again. I would leave them like that but that's just preference.
- *Too many arguments*: They are not easily put together in a wrapping struct since the parameters don't relate semantically (Ex: fn new with a log, a reference to the chain, a peer, etc) but some may differ.
- *Needless returns* were indeed needless

- The state machine works as follows:

- `Busy` => finished ? if so and there are new pending responses then `Busy`, if not then `Idle`
=> not finished remains `Busy`
- Add an `InboundInfo` for readability

- Remove the error variants from `RPCCodedResponse` and use the codes instead
- Fix various spelling mistakes because I got sloppy last time

When parsing deposit logs, we were returning an error in case `PublicKeyBytes` or `SignatureBytes` didn't convert to valid bls `PublicKey` or `Signature` types. This would stall our import of deposit logs.

## Issue Addressed
Closes#1319
## Proposed Changes
This issue:
1. Allows users to edit their Graffiti via the cli option `--graffiti`. If the graffiti is too long, lighthouse will not start and throw an error message. Otherwise, it will set the Graffiti to be the one provided by the user, right-padded with 0s.
2. Create a new `Graffiti` type and unify the code around it. With this type, everything is enforced at compile-time, and the code can be (I think...) panic-free! :)
## Additional info
Currently, only `&str` are supported, as this is the returned type by `.arg("graffiti")`.
Since this is user-input, I tried being as careful as I could. This is also why I created the `Graffiti` type, to make sure I could check as much as possible at compile time.
