`SyncCommitteeMsgPool` grouped messages by their `beacon_block_root`.
This is problematic around sync committee period boundaries and forks.
Around sync committee period boundaries, members from both the current
and next sync committee may sign the same `beacon_block_root`; mixing
the signatures from both committees together is a mistake. Likewise,
around fork transitions, the `signing_root` changes, so those messages
also need to be segregated.
The validator beacon APIs `getAttesterDuties`, `getProposerDuties`, and
`getSyncCommitteeDuties`, have reported the `execution_optimistic`
state for the current head block. This can lead to a race if duties are
requested around the slot start, if a new head block is currently being
processed by the EL, during which the BN head may be briefly optimistic.
`execution_optimistic` is documented in beacon APIs as:
> True if the response references an unverified execution payload.
> Optimistic information may be invalidated at a later time.
> If the field is not present, assume the False value.
As the duty endpoints reference the shuffling dependent root instead of
the currently selected head block, `execution_optimistic` is now fetched
based on that shuffling dependent block root. As this dependent block is
in the past it doesn't usually become optimistic when adding new blocks.
Note that the endpoints requested 4/8 seconds into the slot that perform
the actual duties instead of just querying for duty schedule, still
report `execution_optimistic` based on the BN head block.
When fetching historical `getSyncCommitteeDuties` for the very first
sync committee period, the case must be handled where Altair may not
have been scheduled on a sync committee period boundary.
* fix SSZ response for `produceBlindedBlock`
In `produceBlindedBlock`, we sent the `ForkedBlindedBeaconBlock` when
requested to reply in SSZ format. However, expected result is just the
inner `ForkyBlindedBeaconBlock` together with `eth-consensus-version`.
Note: We do not use SSZ format in our VC for this endpoint at this time,
which explains why we haven't noticed earlier.
* fix Altair/Phase0
The `SAFE_SLOTS_TO_UPDATE_JUSTIFIED` constant is no longer used as the
bouncing attack fix was removed:
https://github.com/ethereum/consensus-specs/pull/3290
Note: Some test networks still define the constant, ignoring the config
constant for now until it is no longer used.
Add compatibility with https://github.com/ethereum/beacon-APIs/pull/290
to the beacon node. Behaviour when configured with multiple ELs is not
specified; intention suggests to indicate whether all ELs are offline.
The consensus-spec-tests already cover the scenarios of our custom test
runner, so the custom tests can be removed. Also cleans up unused config
flags and related unreachable logic.
Two fixes to `/eth/v1/debug/fork_choice`:
- `validity` enum is expected to be serialized as string instead of int
- `data` wrapper is not expected for this endpoint
Syncs the `/eth/v1/debug/fork_choice` REST endpoint with latest specs.
- Validity is now reported as tri-state `enum` instead of two `bool`s
- Response includes store's justified and finalized checkpoints
- Additional `ExtraData` field on outer layer (empty for now)
https://github.com/ethereum/beacon-APIs/pull/232
* Refactor nimbus_signing_node to support Unix signals.
* Fix SN unable to close REST server properly.
* Fix `keys`, `deposit` and `validator_registration` endpoints issues.
Add getValidatorExitSignature() and getDepositMessageSignature() to validator_pool.
* Add /reload endpoint and implementation.
Fix signData to not cancel `timer`.
Fix validator_pool should clear attachedValidators table.
* Diva protocol enhancement implementation.
Just the variable, not yet `lcDataForkAtStateFork` / `atStateFork`.
- Shorten comment in `light_client.nim` to keep line width
- Do not rename `stateFork` mention in `runProposalForkchoiceUpdated`.
- Do not rename `stateFork` in `getStateField(dag.headState, fork)`
Rest is just a mechanical mass replace
* Support for driving multiple EL nodes from a single Nimbus BN
Full list of changes:
* Eth1Monitor has been renamed to ELManager to match its current
responsibilities better.
* The ELManager is no longer optional in the code (it won't have
a nil value under any circumstances).
* The support for subscribing for headers was removed as it only
worked with WebSockets and contributed significant complexity
while bringing only a very minor advantage.
* The `--web3-url` parameter has been deprecated in favor of a
new `--el` parameter. The new parameter has a reasonable default
value and supports specifying a different JWT for each connection.
Each connection can also be configured with a different set of
responsibilities (e.g. download deposits, validate blocks and/or
produce blocks). On the command-line, these properties can be
configured through URL properties stored in the #anchor part of
the URL. In TOML files, they come with a very natural syntax
(althrough the URL scheme is also supported).
* The previously scattered EL-related state and logic is now moved
to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
in a follow-up commit). State is assigned properly either to the
`ELManager` or the to individual `ELConnection` objects where
appropriate.
The ELManager executes all Engine API requests against all attached
EL nodes, in parallel. It compares their results and if there is a
disagreement regarding the validity of a certain payload, this is
detected and the beacon node is protected from publishing a block
with a potential execution layer consensus bug in it.
The BN provides metrics per EL node for the number of successful or
failed requests for each type Engine API requests. If an EL node
goes offline and connectivity is resoted later, we report the
problem and the remedy in edge-triggered fashion.
* More progress towards implementing Deneb block production in the VC
and comparing the value of blocks produced by the EL and the builder
API.
* Adds a Makefile target for the zhejiang testnet
* Fix issue when VC unable to detect errors properly and act accordingly.
Switch all API functions used by VC to RestPlainResponse, this allows us to print errors returned by BN servers.
* Fix issue when prepareBeaconCommitteeSubnet() do not perform actions when BN is optimistically synced only.
* Fix Defect issue.
* Fix submit/publish returning `false` when operation was successful.
* Address review comments.
* Fix some client calls unable to receive `execution_optimistic` field, mark BN as OptSynced when such request has been made.
* Adjust warning levels.

This commit removes ForkySignedBeaconBlockMaybeBlobs and all
references. I tried to pull that thread only as little as was needed
to get rid of it. Left a placeholder BlobSidecar array (in lieu of
Opt[BlobsSidecar]) in a few places; this will be used as we rebuild
the decoupled implementation.
Other changes:
Renamed the `EIP_4844_FORK_*` config constants to `DENEB_FORK_*` as
this matches the latest spec and it's already used in the official
Sepolia config.
We do a linear scan of all pubkeys for each validator and slot - this
becomes expensive with large validator counts.
* normalise BN/VC validator startup logging
* fix crash when host cannot be resolved while adding remote validator
* silence repeated log spam for unknown validators
* print pubkey/index/activation mapping on startup/validator
identification
Extends fork choice state to also track slot numbers to improve accuracy
of `/eth/v1/debug/fork_choice` endpoint. Autoenable this API on devnet,
and disable some extra checks on devnet to aid focused testing efforts.
Align fork choice pruning logic with API based on checkpoints vs root.
