Gnosis uses `MIN_EPOCHS_FOR_BLOCK_REQUESTS` = 33024, but the computed
safe minimum (that Nimbus was using) is 2304. Relax the compatibility
check to allow `MIN_EPOCHS_FOR_BLOCK_REQUESTS` above the safe minimum
and honor `config.yaml` preferences for `MIN_EPOCHS_FOR_BLOCK_REQUESTS`.
* make `MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS` configurable
Gnosis uses custom `MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS` to account
for the faster slot timing, so that blobs still remain available for
roughly the same amount of real time.
Also extend REST config endpoint with full config form `v1.4.0-beta.4`,
and extend compatibility checks when loading configs to reduce warnings.
* Add slashing database pruning to VC.
Fix GetBlockHeaderResponse object declaration (spec has been changed).
* Switch to getFinalizedBlockHeader instead.
* Fix proper sign.
Add statements.
Show pruning log statement only when pruning happens.
* Optimize and remove debugging helpers.
Holesky genesis.ssz file may be unavailable due to quota limits on
`eth-clients/holesky`; do not download it by default during checkout.
Nimbus will download it on first startup from a mirror instead.
In `v1.4.0-alpha.0`, the blob index validation on gossip was changed to
use `compute_subnet_for_blob_sidecar` instead of having a separate topic
for each individual blob. We updated the spec reference in #5363 without
updating the code accordingly. Fixing this now, and also adding the new
`MAX_BLOBS_PER_BLOCK` check from `v1.4.0-beta.3` as it shares the theme.
`v1.4.0-beta.4` made the Gossip rules more strict and now requires to
ignore blobs from other branches if there are equivocating blocks.
Those blobs are only requestable via Req/Resp.
Fix regression from #4808 where blobs that are already known are issued
ACCEPT verdict, propagating them to peers over and over again.
`validateBlobSidecar` contains the correct IGNORE logic. Moved it above
the expensive checks to retain the performance of the check.
Capacity should be set to theoretical limit to ensure correct hash root.
Actual length may be shorter. Only use is `ExecutionPayloadForSigning`
so it doesn't matter yet in practice, but still worth fixing.
Using trusted node sync currently requires to run two commands -
first the `trustedNodeSync` command to initialize the database,
followed by the regular startup command to continue syncing.
The `trustedNodeSync` options are now also available during regular
startup, and are used when the database is empty to simplify setting up
a new Nimbus beacon node. This also aligns behaviour closer with other
Ethereum consensus implementations.
The new logic only applies if the database has not yet been initialized;
same as before. Also, the database needs to be removed under the same
conditions as before when a fresh sync is desired.
Move KZG trusted setup initialization before `BeaconNode.init` to avoid
edge case where network message is received and processed before crypto
library has been properly initialized. Followup from #4870.
