Rick WTM-72

This release contains important optimizations that reduce the propagation times of new blocks on the network. It is recommended that all users upgrade to this version as block propagation delays directly impact validator profits.

Additionally, an upgrade to a upstream dependency (tokio) contains an important fix to a runtime panic. See #2099 for more detail.

Dr. Wong

This minor release contains some important protection from excessive resource consumption in some uncommon cases (#2130). We recommend all users update both their BNs and VCs to this version.

The breaking changes in this release should be insignificant for most, see below for more information.

New Features

The most notable feature is the new "validator monitor" that allows a BN to provide additional logging and metrics for specific validators.

This provides the long-awaited "validator balance" metric and many, many others.

Additionally, you get additional logs about your validators activities (e.g. attestation inclusion in blocks).

See the validator monitor docs for more information.

Breaking Changes

Breaking changes are fairly minor in this release, but may have edge-case impacts for those running custom or non-Lighthouse validator clients.

• Disallow attestation production earlier than head (#2130)
  • Does not permit the creation of AttestationData via the API for slots earlier than the head. This is a fast patch to an immediate issue, in the future we plan to implement a more flexible solution with #2169.

All Changes

• Detailed validator monitoring (#2151)
• Fix bug from #2163 (#2165)
• Disallow attestation production earlier than head (#2130)
• Represent slots in secs instead of millisecs (#2163)

Helium-Q

We strongly recommend all users running v1.0.4 or earlier to update to v1.0.6. However, users on v1.0.5 who are not experiencing issues can safely skip this update.

This release fixes two bugs in v1.0.5 which accidentally caused two breaking changes:

• The --beacon-node flag was no longer respected (#2121)
• The slasher database became invalid (#2125)

Although these bugs were not security risks, they caused significant user frustration during the holiday period. We apologize for any stress and inconvenience caused. Our testing suite is generally focused on catching high-severity logic bugs but we will work to expand it to prevent API breakages like this.

Summary

• Version v1.0.6 (#2126)
• Remove default beacon node value from clap (#2121)
• Fix slasher database schema migration to v2 (#2125)
• Tweak error messages for ease of investigation (#2122)

Baby Legs

We strongly recommend all users upgrade to v1.0.5 as it contains an important fix for subnet discovery (#2095) and dependency updates (#2084).

Feature: BN Redundancy

This release allows the VC to connect to multiple BNs. This means one can use lighthouse vc --beacon-nodes to direct a validator client at multiple BNs. Whenever a BN fails to respond, the VC will try again on the next BN.

Example

lighthouse vc --beacon-nodes http://localhost:5052,http://192.168.1.100:5052

If localhost goes down (perhaps during an update), the VC will attempt to use 192.168.1.100 instead.

Summary

• Version v1.0.5 (#2117)
• Tidy slasher logs for known slashings (#2108)
• Update libp2p (#2101)

Tall Morty

We recommend all users upgrade to v1.0.4, particularly users who have previously experienced database corruption, or who are running a slasher. Please see below for details of breaking changes, including removal of the websocket server.

Breaking Changes

• Removed the legacy websocket server in favour of the standardised server-sent-events API (#1920).
• Disabled Medalla and other legacy testnet support by default, improving compilation time (#1989)

Summary

• Improved handling of I/O errors during block processing. We hope that this spells the end of corrupt databases and resyncs! (#2068)
• Fix a bug in the slasher that caused it to miss some blocks (#2047).
• Networking improvements that strengthen peering, and may improve attestation effectiveness (#2075, #2041).
• New --eth1-purge-cache flag that can be used to clean out the Eth1 cache without a resync. This should only be used if your node is unable to recover from an error like FailedToInsertDeposit(NonConsecutive {..}). The flag is supplied to the beacon node command like so: lighthouse bn --eth1-purge-cache (#2039).

All Changes

• Softer penalties for missing blocks (#2075)
• Multiarch docker GitHub actions (#2065)
• Revert fork choice if disk write fails (#2068)

Ricktiminus Sancheziminius

We recommend all users to upgrade to v1.0.3, especially if they're experiencing timeouts with their eth1 endpoint.

Please note

Users may see a new log message:

Nov 30 21:04:28.268 WARN Syncing eth1 block cache   est_blocks_remaining: initializing deposits, msg: sync can take longer when using remote eth1 nodes, service: slot_notifier

This log indicates that your beacon node is downloading blocks and deposits from your eth1 node. When the est_blocks_remaining is initializing_deposits, your node is downloading deposit logs. It may stay in this stage for several minutes. Once the deposits logs are finished downloading, the est_blocks_remaining value will start decreasing.

It is perfectly normal to see this log when starting a node for the first time or after being off for more than several minutes.

If this log continues appearing sporadically during operation, there may be an issue with your eth1 endpoint.

Summary

• Increasing timeouts and decreases payload size for log request from eth1 nodes.
• Reduces the impact of timeouts when they do occur.
• Logs information about eth1 syncing whilst users are waiting for genesis.
• Adds the lighthouse bn --private flag which zeros-out graffiti and does not publish client information in the identify protocol.

All Changes

• Add privacy option (#2016)
• Improve eth1 block sync (#2008)
• No string in slog (#2017)
• Update PGP key in README (#1986)
• Drop discovery log to trace (#2007)

Juggling Rick

We recommend all users to upgrade to v1.0.2, especially if they're intending to stake with a genesis validator.

This release updates core dependencies in Lighthouse and is highly encouraged for all nodes to run for mainnet.

Summary

• Updates the core executor to a tokio 0.3 runtime and modifies the structure of the task executor
• Updates libp2p (security fixes, spec incompatibility updates)
• Updates BLST to the latest official version of BLST
• UPnP handling improvements

All Changes

• Upgrade to tokio 0.3 and related core sub-dependencies (#1839)
• Update BLST to the latest version (#1979)
• Fix type in docs (#1990)

Investment Rick

We recommend all users to upgrade to v1.0.1, especially if they're intending to stake with a genesis validator.

Since this release affects lockfiles, users should be especially cautious that there is no other lighthouse vc process running on the same host when upgrading to this release. Running two validator clients at the same time, with the same keys can lead to slashing.

Summary

• Changes to flock-based lockfiles which alleviates the need for users to run with --delete-lockfiles after an abrupt shutdown.
• Adds the --eth1-endpoints flags which alllows for redundant eth1 nodes.
• Adds the --metrics flag (and other related flags) to lighthouse vc, allowing for Prometheus metrics.
  • Example dashboard found here: https://github.com/sigp/lighthouse-metrics/blob/master/dashboards/ValidatorClient.json

All Changes

• Fallback nodes for eth1 access (#1918)
• Disable snappy in LevelDB to fix build issues (#1983)
• Log better error message (#1981)
• Use OS file locks in validator client (#1958)
• Sync metrics (#1975)
• Add metrics to VC (#1954)
• Fix #1964: remove mainnet warnings which no longer apply (#1970)
• Update ENR construction and mainnet bootnodes (#1968)
• FAQ/Doc updates (#1966)
• Update docs whenever unstable changes (#1969)
• Status race condition (#1967)
