* fix REST liveness endpoint responding even when gossip is not enabled
* fix VC exit code on doppelganger hit
* fix activation epoch not being updated correctly on long deposit
queues
* fix activation epoch being set incorrectly when updating validator
* move most implementation logic to `validator_pool`, add tests
* ensure consistent logging between VC and BN
* add docs
* Types and scaffolding for EIP-4844
This commit adds the EIP-4844 spec types, and fills in
scaffolding/boilerplate for the use of these types across the repo.
None of the actual EIP-4844 logic is introduced yet.
This follows the pattern used by @tersec when introducing Capella (#4276).
* use eth2-networks fork
* review feedback: add static check EIP4844_FORK_EPOCH == FAR_FUTURE_EPOCH
* review feedback: remove EIP4844 from /eth/v1/config/spec response
* Cleanup / review feedback
* Fix REST test
* Initial commit.
* NextAttestationEntry type.
* Add doppelgangerCheck and actual check.
* Recover deleted check.
* Remove NextAttestainEntry changes.
* More cleanups for NextAttestationEntry.
* Address review comments.
* Remove GENESIS_EPOCH specific check branch.
* Decrease number of full epochs for doppelganger check in VC.

When the EL/Builder fails to produce an execution payload, we fall back
to an empty `ExecutionPayload`. Even though it contains no transactions
it should refer to the configured fee recipient. This is useful for
privacy reasons (do not reveal the reason for the empty payload) and for
compliance with additional fee recipient rules by staking pools.
* move duty tracking code to `ActionTracker`
* fix earlier duties overwriting later ones
* re-run subnet selection when new duty appears
* log upcoming duties as soon as they're known (vs 4 epochs before)
* detect mismatch of config and binary
When loading configuration that sets keys that Nimbus bakes into the
binary at compile-time, raise an error if the config is incompatible
instead of ignoring the conflicting value.
Since these files may have been created in a previous run or manually,
we want to keep loading them even on nodes that don't enable the
keystore API (for example static setups)
Other changes:
* log keystore loading progressively (#3699)
* print initial fee recipient when loading validators
* log dynamic fee recipient updates
* more efficient forkchoiceUpdated usage
* await rather than asyncSpawn; ensure head update before dag.updateHead
* use action tracker rather than attached validators to check for next slot proposal; use wall slot + 1 rather than state slot + 1 to correctly check when missing blocks
* re-add two-fcU case for when newPayload not VALID
* check dynamicFeeRecipientsStore for potential proposal
* remove duplicate checks for whether next proposer
* Harden block proposal against expired slashings/exits
When a message is signed in a phase0 domain, it can no longer be
validated under bellatrix due to the correct fork no longer being
available in the `BeaconState`.
To ensure that all slashing/exits are still valid, in this PR we re-run
the checks in the state that we're proposing for, thus hardening against
both signatures and other changes in the state that might have
invalidated the message.
* fix same message added multiple times
in case of attestation slashing of multiple validators in one go
* Fixes a segfault during block production when the Keymanager API
is disabled. The Keymanager is now disabled on half of the local
testnet nodes to catch such problems in the future.
* Fixes multiple potential stalls from REST requests being done
without a timeout. From practice, we know that such requests
can hang forever if not cancelled with a timeout. At best,
this would be a resource leak, at worst, it may lead to a
full stall of the client and missed validator duties.
* Changes some Options usages to Opt (for easier use of valueOr)
When the client was started without any validators, the doppelganger
detection structures were never initialized properly. Later, when
validators were added through the Keymanager API, they interacted
with the uninitialized doppelganger detection structures and their
duties were inappropriately skipped.
* Keymanager API for the validator client
* Properly treat the 'description' field as optional when loading Keystores
* Spec-compliant serialization of the slashing data in Keymanager's DeleteKeys response ()
Fixes#3940Fixes#3964Closes#3884 by adding test
In order to avoid full replays when validating attestations hailing from
untaken forks, it's better to keep shufflings separate from `EpochRef`
and perform a lookahead on the shuffling when processing the block that
determines them.
This also helps performance in the case where REST clients are trying to
perform lookahead on attestation duties and decreases memory usage by
sharing shufflings between EpochRef instances of the same dependent
root.
* MEV validator registration
* add nearby canary to detect new beacon chain forks
* remove special MEV graffiti
* web3signer support
* fix trace logging
* Nim 1.2 needs raises Defect
* use template rather than proc in REST JSON parsing
* use --payload-builder-enable and --payload-builder-url
* explicitly default MEV to disabled
* explicitly empty default value for payload builder URL
* revert attestation pool to unstable version
Other changes:
* The Keymanager error responses differ from the Beacon API responses.
'keymanagerApiError' replaces the former usages of 'jsonError'.
* Return status code 401 and 403 for authorization errors in accordance
to the spec.
* Eliminate inconsistencies in the REST JSON parsing. Some of the code
paths allowed missing fields.
* Added logging of serialization failure details at DEBUG level.
