status-im/nimbus-eth2 v23.11.0

on GitHub

Notes

Nimbus v23.11.0 is a low-urgency upgrade bringing enhanced support for the Obol DVT middleware, further profit optimisations for the Nimbus validator client and a simplified and safe alternative to the trusted node sync.

Improvements

• The new options external-beacon-api-url, trusted-block-root and trusted-state-root enable simple bootstrapping through the light client protocol and a non-trusted Beacon API provider:
  https://nimbus.guide/start-syncing.html#checkpoint-sync
  #5545

• Improved scoring algorithms allow the Nimbus validator client to maximize block rewards when working with multiple beacon nodes:
  #5447

• Nimbus now supports the /eth/v1/validator/beacon_committee_selections and /eth/v1/validator/sync_committee_selections Beacon API endpoints used by the Charon Obol middleware:
  #5375

• Efficient bulk write operations to the slashing protection database bring significant performance improvements when operating very large number of validators on a single machine (e.g. more than 10K):
  #5604

• Nimbus now disconnects peers who are behaving poorly with respect to the beacon chain request/response protocols and peers who are exceeding the GossipSub rate limits:
  #5579
  #5482

• The Nimbus guide now features light and dark themes:
  #5564

• Nimbus now honours the MIN_EPOCHS_FOR_BLOCK_REQUESTS network configuration parameter:
  #5590

Fixes

• The REST API endpoint /eth/v1/node/peers_count was producing an incorrectly encoded numeric response:
  #5548

• The REST API endpoint eth/v2/beacon/blocks was not handling the broadcast_validation parameter in accordance to the spec:
  #5531

• The validator client slashing database was not pruned:
  #5551

• Light clients following the event stream of light client updates delivered through the REST API or the P2P protocols were at risk of getting stuck due to missing notifications for certain key events:
  #5602
  ethereum/consensus-specs#3549

• Regression in v23.10.0 was preventing the Nimbus validator client from registering its validators with the external builder when no validators have been attached to the associated beacon node, effectively disabling the usage of the builder:
  #5603

• Nimbus was not retrying certain syncing requests after receiving an invalid response from a peer:
  #5615

• A theoretical possibility where Nimbus may fail to start after a clean shutdown has been addressed:
  #5617

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks

medium-urgency: may contain an important stability fix, it is better to update sooner rather than later

high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly
