status-im/nimbus-eth2 v22.12.0

on GitHub

Notes

Nimbus v22.12.0 is a medium-urgency release which improves the doppelganger detection in the Nimbus validator client through the use of standardized APIs that are compatible with all third-party beacon nodes. Furthermore, it addresses several inconsistencies in the behavior between the stand-alone beacon node and the validator client. This release also allows users of trusted node sync to skip downloading the entire history of validator deposits by syncing against a server that supports the standardized /eth/v1/beacon/deposit_snapshot REST endpoint.

Improvements

• 60% more efficient block replaying speed brings faster REST responses and
  more resilience on the network in the face of heavy forking activity and
  non-finalization:

  #4435

• Support for obtaining a deposit snapshot during trusted node sync from
  servers supporting the standardized /eth/v1/beacon/deposit_snapshot
  REST endpoint:

  https://nimbus.guide/trusted-node-sync.html#skip-syncing-the-history-of-deposits
  #4303

• Official docker images for the Nimbus validator client are now available:

  https://hub.docker.com/r/statusim/nimbus-validator-client
  #4439

• The skip_randao_verification query parameter is now also supported in
  the /eth/v1/validator/blinded_blocks/{slot} API endpoint:

  #4435

• The doppelganger detection in the Nimbus validator client is now based on
  the standardized /eth/v1/validator/liveness/{epoch} REST endpoint:

  #4381

• The validator client will now use with the standard exit code 129 in
  case of detected doppelganger on the network:

  #4398

Fixes

• A potential false-positive in the doppelganger detection logic:

  #4398

• A potential hang in trusted node sync:

  #4303

Breaking changes:

• The built-in support for the Ropsten testnet has been removed:

  #4280

  You can still connect to the Ropsten network by specifying its
  metadata directory on the command line through the --network
  parameter.

• The statusim/nimbus-eth2 docker image no longer includes the
  nimbus_validator_client binary and the shell scripts included
  in the release tarballs. Please use the new dedicated image for
  the Nimbus validator client.

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
