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.
When using trusted node sync with light client (`--trusted-block-root`),
the trust assumption on the server is reduced to solely be responsible
for data availability, but not data correctness. This means that we must
check block proposer signatures against the downloaded checkpoint, as
they are not covered by the block root.
Note that this lowers the backfill speed when using LC based CP sync
due to the extra checks, by about 60% for me.
Post-Capella, historical roots are computed from historical summaries
instead of being directly stored in the beacon state.
Slightly messy to pass both lists around - this is done to avoid
computing the historical root unnecessarily.
* low attestations during epoch should instafail in CI; dbg -> warn level on newPayload log
* improve newPayload warning message when no valid EL connected
* reduce potential spam; make log spelling more consistent; use fatal/quit
Post-Deneb, when the request manager receives a missing block from a
peer, it needs to check if the corresponding blobs are available, and
if so pass them along. If they aren't available, the newly-fetched
block must be put in blobless quarantine (while the blobs are
retrieved, coming in next commit).
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.
* Fix durationToNextSlot() and durationToNextEpoch() to work not only after Genesis, but also before Genesis.
Change VC pre-genesis behavior, add runPreGenesisWaitingLoop() and runGenesisWaitingLoop().
Add checkedWaitForSlot() and checkedWaitForNextSlot() to strictly check current time and print warnings.
Fix VC main loop to use checkedWaitForNextSlot().
Fix attestation_service to run attestations processing only until the end of the duty slot.
Change attestation_service main loop to use checkedWaitForNextSlot().
Change block_service to properly cancel all the pending proposer tasks.
Use checkedWaitForSlot to wait for block proposal.
Fix block_service waitForBlockPublished() to be compatible with BN.
Fix sync_committee_service to avoid asyncSpawn.
Fix sync_committee_service to run only until the end of the duty slot.
Fix sync_committee_service to use checkedWaitForNextSlot().
* Refactor validator logging.
Fix aggregated attestation publishing missing delay.
* Fix doppelganger detection should not start at pre-genesis time.
Fix fallback service sync status spam.
Fix false `sync committee subnets subscription error`.
* Address review comments part 1.
* Address review comments.
* Fix condition issue for near genesis waiting loop.
* Address review comments.
* Address review comments 2.
The 'peek' name was incorrect as it was actually removing from the
table. It was consequently used incorrectly in block processing: the
blobless block wasn't returned to the table when it should be.
* Simplify block quarantine blobless
The quarantine blobless table was initially keyed off of (Eth2Digest,
ValidatorSig). This was modelled off the orphan table. The presence of
the signature in the key is necessary for orphans, because we can't
verify the signature for an orphan. That is not the case for a
blobless block, where the signature can be verified.
So this PR changes the blobless block table to be keyed off a
Eth2Digest only. This simplifies the retrieval and handling of
blobless blocks.
* review feedback
* allow trusted node sync based on LC trusted block root
Extends `trustedNodeSync` with a new `--trusted-block-root` option that
allows initializing a light client. No `--state-id` must be provided.
The beacon node will then use this light client to obtain the latest
finalized state from the remote server in a trust-minimized fashion.
Note that the provided `--trusted-block-root` should be somewhat recent,
and that security precautions such as comparing the state root against
block explorers is still recommended.
* fix
* workaround for `valueOr` limitations
* reduce magic numbers
* digest len > context len for readability
* move `cstring` conversion to caller
* avoid abbreviations
* `return` codestyle
* add `formatIt` for `ForkedLightClientXyz`
Even though the `ForkyLightClientXyz` have `formatIt`, they do not apply
when logging `ForkedLightClientXyz`, leading to large logs at times.
Defining `formatIt` for `ForkedLightClientXyz` fixes this.
* exports not needed
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)

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
* `engine_api_response_time` provides a histogram for the Engine API
response times for each unique pair ot URL and request type.
* All engine API requests are now tracked
Other changes:
The client will no longer exit on start-up if it fails to connect to
a properly configured EL node.
When using `--history=prune`, `dag.tail.slot` may advance beyond the
configured light client data retention period. Update the LC logic so
that the `dag.tail.slot` is no longer considered for LC pruning.
It is still considered to check whether new data can be produced.
* Update sync to use post-decoupling RPCs
blob_sidecars_by_range returns a flat list of sidecars, which must
then be grouped per-slot.
* Add test for groupBlobs
* createBlobs: convert proc to func
* 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.

Sepolia in particular goes through two hard forks during era 1, meaning
the phase0 fork is no longer part of the state, even though blocks that
belong to it still are phase0.
* log validator that triggers doppelganger
* move activity detection closer to where it's performed, record
aggregation as activity (since it's part of the liveness endpoint)
* vc: check for doppelgangers in epoch 0 also (so that activity in epoch
1 can happen)
* avoid some looping when processing activities
* Remove use of beacon_block_and_blobs_sidecar topic
This topic goes away with decoupled blocks and blobs.
* remove use of getBeaconBlockAndBlobsSidecarTopic from test
* update nimbus_light_client.nim
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.
