Consensys-Incorporated/teku 21.6.1

v21.6.1

on GitHub

Upcoming Breaking Changes

• Teku currently publishes a head event on the REST API 4 seconds into a slot even if a block has not been received. In a future release this will be changed so head event is only published when a new
  chain head block is imported. The --Xvalidators-dependent-root-enabled option can be used to switch to the new behaviour now for testing.
  Note: this should be applied to both the beacon node and validator client if running separately.
• The /teku/v1/beacon/states/:state_id endpoint has been deprecated in favor of the standard API /eth/v1/debug/beacon/states/:state_id which now returns the state as SSZ when the Accept: application/octet-stream header is specified on the request.

Additions and Improvements

• Use batch verification for gossiped attestations to reduce CPU usage. This can be disabled with --Xp2p-batch-verify-attestation-signatures-enabled=false.
• Fixed issues in discv5 PING and PONG message handling which resulted in not updating peer's ENR records correctly.
• Implement alpha.7 spec updates to sync committee logic and rewards.
• deposit_data files generated by the deposit-cli tool in the validator keys directory are now automatically ignored. Thanks to Vishal Jhala.
• Added new metrics to report on the progress of Eth1 block voting:
  • beacon_eth1_current_period_votes_max - Maximum number of votes possible in the current voting period.
  • beacon_eth1_current_period_votes_total - Number of votes cast so far in the current voting period.
  • beacon_eth1_current_period_votes_best - Number of votes for the leading candidate in the current voting period.
  • beacon_eth1_current_period_votes_unknown - Number of votes for blocks this node considers invalid (e.g. unknown blocks).
  • beacon_eth1_current_period_votes_current - Number of votes for the value in the current state (the default vote per the spec).
  • beacon_eth1_block_cache_size - Total number of blocks stored in the Eth1 block cache.

Bug Fixes

• Prevent LevelDB transactions from attempting to make any updates after the database is shut down.
• Update /eth/v1/node/health to return 206 while node is starting up rather than a 200.
• Fixed issue which cause a small reduction in attestation rewards when using --Xvalidators-dependent-root-enabled.
• Fixed issue with eth1 follow distance tracking revealed in Rayonism testnets. Teku incorrectly strictly follows 2048 blocks before the eth1 head but the follow distance should be based on timestamp, not block number.
  This change can be disabled with --Xeth1-time-based-head-tracking-enabled=false if required.

Experimental: New Altair REST APIs

• implement POST /eth/v1/beacon/pool/sync_committees to allow validators to submit sync committee signatures to the beacon node.
• implement POST /eth/v1/validator/duties/sync/{epoch} for Altair fork.
• implement GET and POST /eth/v1/validator/sync_committee_subscriptions for Altair fork.
• implement GET /eth/v2/validator/blocks/{slot} for Altair fork.
• implement GET /eth/v2/debug/beacon/states/:state_id for Altair fork.
• implement GET /eth/v1/beacon/states/{state_id}/sync_committees for Altair fork.
• /eth/v1/validator/blocks/{slot} will now produce an altair block if an altair slot is requested.
• /eth/v1/node/identity will now include syncnets in metadata
