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
We currently use `BlockError` for both beacon blocks and LC objects.
In light of EIP4844, we will likely also use it for blob sidecars.
To avoid confusion, renaming it to a more generic `VerifierError`,
and update its documentation to be more generic.
To avoid long lines as a followup, also renaming the `block_processor`'s
`BlockProcessingCompleted.completed`->`ProcessingStatus.completed` and
`BlockProcessingCompleted.notCompleted`->`ProcessingStatus.notCompleted`
This PR removes a bunch of code to make TNS aware of era files, avoiding
a duplicated backfill when era files are available.
* reuse chaindag for loading backfill state, replacing the TNS homebrew
* fix era block iteration to skip empty slots
* add tests for `can_advance_slots`
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.
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.
* 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
Per spec, we should not be sending our detected terminal block to EL -
the EL configuration exchange should only look at values from
configuration and report mismatches.
When there are a lot of deposits, we decompress the public key into a
crypto cache. To avoid having those caches grow unreasonably big,
make sure to operate on the decompressed pubkey instead.
