This will consider all gossipsub messages that have either the `from`, `seqno` or `signature` field as invalid.
## Additional Info
We should not merge this until all other clients have been sending empty fields for a while.

## 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.
## Issue Addressed
Closes#1076
## Proposed Changes
Remove an extra unnecessary decompression of the deposit public key from `process_deposit`. The key is decompressed and used to verify the signature in `verify_deposit_signature`, making this initial decompression redundant.
## Additional Info
This is _not_ a consensus-breaking change because keys which previously failed the early decompression check will not be found in the pubkey cache (they are invalid), and will be checked and rejected as part of `verify_deposit_signature`.
## Issue Addressed
#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.

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.

Bounding the error_message that can be returned for RPC domain errors
Co-authored-by: Age Manning <Age@AgeManning.com>
## Proposed Changes
This is an extraction of the quoted int code from #1569, that I've come to rely on for #1544.
It allows us to parse integers from serde strings in YAML, JSON, etc. The main differences from the code in Paul's original PR are:
* Added a submodule that makes quoting mandatory (`require_quotes`).
* Decoding is generic over the type `T` being decoded. You can use `#[serde(with = "serde_utils::quoted_u64::require_quotes")]` on `Epoch` and `Slot` fields (this is what I do in my slashing protection PR).
I've turned on quoting for `Epoch` and `Slot` in this PR, but will leave the other `types` changes to you Paul.
I opted to put everything in the `conseus/serde_utils` module so that BLS can use it without a circular dependency. In future when we want to publish `types` I think we could publish `serde_utils` as `lighthouse_serde_utils` or something. Open to other ideas on this front too.
This reverts commit 2627463366.
## Issue Addressed
This is a temporary fix for #1589, by reverting #1574. The Docker image needs to be built with `--build-arg PORTABLE=true`, and we could probably integrate that into the multi-arch build, but in the interests of expediting a fix, this PR opts for a revert.
Converts the graffiti binary data to string before printing to logs.
## Issue Addressed
#1566
## Proposed Changes
Rather than converting graffiti to a vector the binary data less the last character is passed to String::from_utf_lossy(). This then allows us to call the to_string() function directly to give us the string

## Issue Addressed
N/A
## Proposed Changes
- Fix a wrong command in the validator generation example.
- Replace occurrences of 'passphrase' with 'password'. This is mostly because I felt that there was a lot of mixing of the two phrases in the documentation and the actual commands which is a bit confusing. Picked 'password' everywhere because it felt more appropriate but I don't mind changing it to 'passphrase' as long it's consistent everywhere.

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
Any users who have experienced pruning errors on Medalla will need to resync after upgrading to a release including this change. This should end unbounded `chain_db` growth! 🎉
## Issue Addressed
Fixes#1552
## Proposed Changes
Earlier, we were always loading the hardcoded default testnet config which is a mainnet spec. So running lighthouse with `--spec` option anything other than mainnet gave errors because we tried loading a mainnet genesis spec with `minimal`/`interop` flags.
This PR fixes the order of loading such that we load the hardcoded default spec only if neither `--testnet` and `--testnet-dir` flags are present.
## Issue Addressed

## 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.

## Proposed Changes
All peers with the same IP will be considered banned as long as there are more than 5 (constant) peers with this IP that have a score below the ban threshold. As soon as some of those 5 peers get unbanned (through decay) and if there are then less than 5 peers with a score below the threshold the IP will be considered not banned anymore.

## Proposed Changes
Refactor attestation service to send out requests to find peers for subnets as soon as we get attestation duties.
Earlier, we had much more involved logic to send the discovery requests to the discovery service only 6 slots before the attestation slot. Now that discovery is much smarter with grouped queries, the complexity in attestation service can be reduced considerably.

## 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

## Proposed Changes
- Fixes a mistake I made in #1530 which resulted us in *not* rejecting attestations that we intended to reject.
- Adds skip-slot checks for blocks earlier in import process, so it rejects gossip and RPC blocks.
