Summary

This release significantly improves peer stability and is recommended for any user who is seeing an erratic peer-count and/or missing attestations due to InsufficientPeers.

In addition to peer stability improvements, this release also contains:

• Eth2 Key Manager API support for the validator client (#2736)
• Docker Hub images with CPU-optimized "modern" BLST (#2966)
• Support for --network gnosis (#2931)

Peer Scoring Stability

There appears to be a significant portion of peers which are transmitting late messages on the p2p gossip network. The cause is yet to be determined and it's clear that more time will be required to investigate. The late messages are not likely to consume a significant amount of system or network resources, so it seems beneficial to network stability to temporarily tolerate peers who exhibit this behaviour (see (#2976). Once the cause(s) of the late messages is/are determined, we will revisit the peer-scoring parameters.

Optimized Docker Images

If you are running Lighthouse under Docker on a modern CPU then you can probably upgrade to the latest-modern tag for a 20-30% speed-up on signature verification.

If you are running the Lighthouse image manually, use latest-modern or v2.1.2-modern in your docker commands, e.g.

docker run sigp/lighthouse:latest-modern

If you are using lighthouse-docker then you can upgrade by setting LIGHTHOUSE_VERSION=latest-modern in your .env file.

To check whether your CPU is compatible with the optimized image, see Portability in the book. For more information on all the available images, see Available Docker Images.

VC and BN Update Procedure

The VC and BN between this release and the previous are compatible. You may update them independently.

Update Priority

This table provides priorities for which classes of users should update particular components.

User Classes and Priorities

Staking users are those who use lighthouse bn and lighthouse vc to stake on the Beacon Chain. Non-staking users are those who run a lighthouse bn for non-staking purposes (e.g., data analysis or applications).

High priority updates should be completed as soon as possible (e.g., hours or days). Medium priority updates should be completed at the next convenience (e.g., days or a week). Low priority updates should be completed in the next routine update cycle (e.g., two weeks).
