status-im/nimbus-eth2 v1.5.1

on GitHub

Nimbus v1.5.1 is a high-urgency release for all users who have already upgraded to v1.5.0. It fixes a deposit contract syncing issue which manifests as the warning message "Eth1 chain not synced".

Under specific circumstances, such a failure to sync the Eth1 chain may result in missed Eth2 block proposals, so affected users are advised to upgrade as soon as possible.

For anyone still running Nimbus v1.4.x or earlier, migrating to v1.5.1 continues to be a medium-urgency but mandatory upgrade that must be installed before October 27th.

Notable changes (v1.5.0)

• Support for the Altair hard fork and the latest Ethereum consensus spec (v1.1.1)

• Our REST API is now feature complete, supporting the full Beacon API specification. This API should not be exposed to the public Internet as it includes multiple endpoints which could open your node to denial-of-service (DoS) attacks.

  • Known limitations: To use the REST API with a validator client, you need to enable the --subscribe-all-subnets option. This requirement will be removed in future versions.

• A new experimental --num-threads=X option allows Nimbus to take advantage of multiple CPU cores when verifying attestations. Set it to 1 to use one worker thread, 2 for two worker threads, etc. The default value is set to 1 in this release, but future versions will set it to 0 (this tells the client to use as many worker threads as there are CPU cores available). N.B .enabling anything other than 1 is considered experimental at this stage.

• Improved peer discovery logic that ensures good connectivity to all gossip subnets.

• A new version metric that makes it easy to keep track of client upgrades within Grafana dashboards.

• New metrics libp2p_peers_identity, libp2p_peers_traffic_read_total, libp2p_peers_traffic_write_total, subdivided through Prometheus labels by the client type of the peer (i.e. nimbus, prysm, teku, lodestar or lighthouse).

• BLST has been upgraded to the latest version (v0.3.5).

• The --network option now accepts a directory with custom network metadata in the format of the eth2-testnets repository. The SECONDS_PER_SLOT configuration value remains the only setting that must be supplied at compile-time through the -d:SECONDS_PER_SLOT=X nim compilation flag.

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
