* Make VC able to understand any type of `/eth/v1/config/spec` response without any changes in source code.
Update compatibility checking.
Now VC is able to obtain any constant from `spec` call.
* Remove RestSpecVC declaration.
* Initial commit.
* Add algorithm in comment.
Remove delays.
Fix logging statement issues.
Change update from epoch to slot.
* Obtain timestamp earlier.
* Add processing delays into algorithm.
* Fix time offset logging to produce integers instead of strings.
* Address review comments.
* Fix copyright year.
Fix updateStatus().
* Remove fields from Slot start log statement.
Fix issues when BN do not support Nimbus Extensions.
Rename metric name and type change.
* Add beacon role to disable time offset check manually.
`nim-serialization` is tagged with `{.raises:[SerializationError].}` so
it is no longer sufficient to catch `SszError` in some situations.
`SszError` inherits from `SerializationError`, so broadening the caught
exception types can be done now, to enable bumping `nim-serialization`.
https://github.com/status-im/nimbus-eth2/pull/5043#issuecomment-1584227993#5061 is also needed to bump `nim-serialization`.
* Refactor api.nim to provide more informative failure reasons.
Distinct between unexpected data and unexpected code.
Deprecate Option[T] usage.
* Fix 400 for produceBlindedBlock().
Get proper string conversion for strategy.
* Fix SSZ encoded versions of ProduceBlockResponseV2, ProduceBlockResponseV2 can be received and decoded.
Fix done() warnings.
Bump presto.
* Fix compilation error with new presto.
Use TcpNoDelay option for Web3Signer.
* Fix produceBlockV2() should provide SSZ responses too.
* Address block encoding issue.
* Fix signing test.
* Bump presto.
* Address review comments.
Use separate functions per format when parsing LC data from REST.
This allows to process events from the eventstream more directly,
as they are always JSON not SSZ. And also makes the code cleaner.
* Initial commit with both methods enabled: `poll` and `event`.
* Address review comments.
* Address review comments.
Fix copyright years.
* After bump fixes.
* 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.
* 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
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
* 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.
* 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.

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.
* Fix getStateRoot() and getBlockRoot() API functions which should obtain `execution_optimistic` field.
Fix sync committee service to check `execution_optimistic` field of getBlockRoot() response.
* 2nd part.
* Remove presets usage.
Distinguish between those code locations that need to be updated on each
light client data format change, and those others that should generally
be fine, as long as a valid light client object is processed.
The former are tagged with static assert for `LightClientDataFork.high`.
The latter are changed to `lcDataFork > LightClientDataFork.None` to
indicate that they depend only on presence of any valid object.
Also bundled a few minor cleanups and fixes.
Also add `Forky` type for `LightClientStore` and minor fixes / cleanups.
In a future fork, light client data will be extended with execution info
to support more use cases. To anticipate such an upgrade, introduce
`Forky` and `Forked` types, and ready the database schema.
Because the mapping of sync committee periods to fork versions is not
necessarily unique (fork schedule not in sync with period boundaries),
an additional column is added to `period` -> `LightClientUpdate` table.
* 60% state replay speedup
* don't use HashList for epoch participation - in addition to the code
currently clearing the caches several times redundantly, clearing has to
be done each block nullifying the benefit (35%)
* introduce active balance cache - computing it is slow due to cache
unfriendliness in the random access pattern and bounds checking and we
do it for every block - this cache follows the same update pattern as
the active validator index cache (20%)
* avoid recomputing base reward several times per attestation (5%)
Applying 1024 blocks goes from 20s to ~8s on my laptop - these kinds of
requests happen on historical REST queries but also whenever there's a
reorg.
* fix test and diffs
Other changes:
* More optimal search for TTD block.
* Add timeouts to all REST requests during trusted node sync.
Fixes#4037
* Removed support for storing a deposit snapshot in the network
metadata.
* 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
* implement several capellaImplementationMissing points
* don't register validator activity for not-active validators
* don't check validator indices already coming out of committees which exist; must be active validators, or else other deeper bugs
The LC REST API has been merged into the ethereum/beacon-APIs specs:
- https://github.com/ethereum/beacon-APIs/pull/247
Update URLs to v1 and update REST tests. Note that REST tests do not
start with Altair, so the tested BN will return empty / error responses.
Implements the latest proposal for providing LC data via REST, as of
https://github.com/ethereum/beacon-APIs/pull/247 with a v0 suffix.
Requests:
- `/eth/v0/beacon/light_client/bootstrap/{block_root}`
- `/eth/v0/beacon/light_client/updates?start_period={start_period}&count={count}`
- `/eth/v0/beacon/light_client/finality_update`
- `/eth/v0/beacon/light_client/optimistic_update`
HTTP Server-Sent Events (SSE):
- `light_client_finality_update_v0`
- `light_client_optimistic_update_v0`
For JSON responses, "eth-consensus-version" header is handled in
`eth2_rest_serialization` for states and `rest_beacon_api` for blocks.
Align them to also be handled in `eth2_rest_serialization` for blocks.
In `eth2_rest_serialization` there was a `dump` function for
`KeystoresAndSlashingProtection` that does not seem to be used.
Removes that unused function.
For pre-encoded JSON REST responses we have `jsonResponsePlain`.
Adds a `sszResponsePlain` function to serve similar purpose for SSZ.
This avoids caller having to explicitly specify Http200 and media type.
