  • Erigon:

    • We need to test the image for aggressive pruning provided by Somnath
    • Checked the logs for Nimbus + Erigon missed slots for devnet 3
      • Could not find a reason why the payloads would be invalid
      • The sequence of requests for payloads might not be optimal on Nimbus’ side (some type of race condition?)
      • There might be a bug in the transaction pool for Erigon during block building
        • Discovered because of a Hive test failure on Ethereum
        • Somnath is looking into it

Client Team Updates

EL

  • Nethermind:

    • No specific updates
    • Preparing a new release with performance improvements
      • RC this week
      • Next week full release
    • One more release with experimental state db changes with large improvements
      • Initial tests were very promising
  • Erigon:

    • Testing change to make validator nodes lighter (better pruning, i.e. just keep receipts for the deposit contract)
    • Somnath will work on a release so we can test it on the devel branch
  • Geth:

    • Not present

Chain Infra

  • Gateway
    • No specific updates
    • Can test new Nethermind releases, just ping Anton on Telegram
      • nethermindeth/nethermind:release-1.25.0

Dencun

  • Chiado
    • Tentative date around end of January, ideally Jan 31st (during the core dev call)
    • Around the same time as Sepolia
    • Lion will run the script to find optimal epochs (right time and epoch boundaries)

Hive Test

  • Migrated more tests for Cancun, but in the process broke withdrawal tests
    • These are being worked on currently

Devnet

  • Solved Nethermind related issues
  • Some issues with Erigon-Teku
  • We had one node missing slots (Erigon + Teku)
    • Technically one forked, but it’s likely because it was out of sync with the network and then produced a block itself
  • We need to add Lighthouse (unstable) and Nimbus (v23.11.0)
  • We need to observe the network a bit more
  • How are Teku nodes configured currently, as the preset isn’t set up in the code base yet?

  • Nethermind:

    • Slowly progressing with Shutter for the parts they can do alone
      • Requested a Docker image from Shutter
  • Merged JSON-RPC related changes that should result in much better performance

    • There might still be some issues
    • Nethermind wants to test this upgrade on the official Gnosis RPC
      • We’re going to start with one node and look at the metrics
      • Maybe it’s a bit early to upgrade all nodes
      • Sending traffic there in a shadow mode / replicate traffic to it without using the return data would be useful
      • This is currently in the master branch, not officially released
    • Working on one regression for a cancun related issue
  • Working on Nethermind 2, a big state redesign that would include performance a lot that would allow for snap servers

    • Probably going to be released after Cancun
  • Erigon:

    • No news in particular
    • Busy working on Caplin and Erigon 3
  • Geth:

    • Can’t join today

Chain Infra

  • Gateway
    • Saw an increase in traffic and had to scale the infrastructure
      • This helped to reveal minor issues that are being worked on

Hive Tests

  • Working on multi client tests for receiving blob transactions at the same time

Devnet

  • Still having some general Nethermind-specific issues
    • Sometimes out of sync
    • One node with a specific issue
  • No issues with the Erigon nodes

Client Team Updates

EL

  • Nethermind:

    • No updates
  • Erigon:

    • No updates
  • Geth:

    • Was able to sync the whole mainnet up to the head block
    • However, none of the progress is getting saved to the database, so restarting the node requires a new sync every time. It also restarts after a full sync.
      • Probably related to the difficulty. Geth seems to expect the difficulty to be the TTD rather than an empty array.
      • This is likely the last issue to fix

Chain Infra

  • Gateway
    • worked on enabling eth_getProof on our Gnosis RPC by forwarding it to the Nethermind nodes, at least for certain customers
    • genome (.gno domains) infra is ready, we are waiting for them to complete whatever legalities

Hive Tests

  • Having some issues with fees regarding blobs

Devnet

  • Added 3 Erigon nodes
    • No issues for now
  • Started transaction fuzzers
    • Already had blob generators
  • Some reorgs are happening, but all nodes fixed themselves (both Erigon and Nethermind)
  • Might have a fix ready for the Nethermind syncing issue but are still testing
  • eth/68 issue potentially resolved as well

October 25, 2023

EL

  • Nethermind:

    • New release with the incident fix and removal of deprecated xdai configs after this call
    • Now has more time to work on Shutter
  • Erigon:

    • Maybe the pruning is suboptimal because the node storage size is fairly big
    • Low priority because they’re focused on Erigon 3 which will change storage significantly anyways
  • Geth:

    • Kept digging into why the new branch isn’t connecting
    • Only works with eth/66 clients but gets rejected by the other side
    • Asked Tanishq and Somnath to sync nodes to get logs / information

Mainnet

  • Mainnet missed epochs: what happened?
    • Nethermind proved that it was possible to build bad blocks with integration tests
      • https://github.com/NethermindEth/nethermind/pull/6212
      • 100% sure that they fixed an edge case
      • Those blocks were built on incorrect state roots
      • There’s a high probability that this was the edge case that happened on mainnet
      • A release for this bug fix is coming very soon
        • This will also include the --config xdai(_archive) removal
      • This bad block situation requires some conditions
        • Specific transactions
        • Specific combination of fork choice request
        • Specific order of events
        • A different transaction pool, restarted Nethermind nodes or Erigon produced blocks could all be reasons to break out of this issue
    • Nethermind is going to go through logs a bit more to confirm
  • Lion: Thank you to the Nethermind team for the debugging efforts even throughout the weekend
    • Wants to write a postmortem because it was quite significant of an issue
    • What can we do to improve this type of situation?
      • Monitoring. We’ve already set up
      • Forkly
      • Loki logs in Grafana
      • Grafana metrics for all client combinations
      • Big block experiment and associated dashboards (in ClickHouse)
    • Access to partners / logs
    • We could also add additional non-pruning nodes (not necessarily archive)
      • We already run archive nodes on dev machines where we can SSH and run arbitrary code
    • Add alerts to post on Telegram
      • In case we see bad blocks
      • If we’re not finalizing
    • In this event we learned it too late (from Butta from Beaconcha.in rather than our own alerts)
    • Nethermind could implement a bad block metric
  • This issue really highlight the need of client diversity
    • Could moving a large portion of the network to Erigon cause more issues?

Chain Infra

  • Gateway
    • Looked at metrics and noticed the issue as well because the RPC had issues
    • Will soon be able to quickly provision rollups on Chiado

Hive Tests

  • No updates

Devnet

  • New devnet (devnet-1) was expected to be spun up today, but this is going to be postponed, most likely to tomorrow
    • Does this work with the mainnet KZG?
      • Nethermind updated it as well, so it should
    • Somnath is going to work on the configs for Erigon

Research

  • Automatic sync tests
    • Lion will check

October 18, 2023

EL

  • Nethermind:

    • Finished some Gnosis-specific features
      • Configurable EIP-4844 configurations
    • Cancun merged to main branch
    • Kickstarted an initiative to rework the eth_getLogs system to optimize it
  • Erigon:

    • Sync issues (OOM on 32 GB nodes also running CL)
      • Exclusively happens in Docker, GOMAXPROC should be a workaround (4 instead of 24 for example)
    • High disk usage (400 GB with --prune=hrtc vs 170 GB on Nethermind for the standard gnosis preset)
    • Fairly unreliable (I have to restart it every few days at this point, maybe too many attached validators? I miss quite a few epochs on mainnet too but don’t need to restart at least.)
    • Configurable EIP-4844 configurations are merged
    • Working on Erigon 3
  • Geth:

    • Tried the static peers and it seems to work better
    • Still not getting a connection
      • The old branch systematically uses eth/66 and that works
      • The new branch gets disconnected when trying to connect to eth/66

Dencun

Chain Infra

  • Gateway
    • Discovered a bug in the load balancer that resulted in 0.5 to 1% of errors at the current load
      • Sudden increase in eth_getLogs, which are typically quite slow on the nodes, which were subsequently falling behind
      • The solution was to account for this slowness

Gnosis

  • The public RPC was down during the weekend, but that was because of Gnosis.

Hive Tests

  • Solved the configuration issues for Dencun
  • Working on an error when sending blobs

Devnet

  • Has Erigon joined?
    • thorax/erigon:docker_gno_dencun_devnet_0
    • --chain=gno_dencun_0
    • Issues with the internal CL
    • Not tested yet

Research

  • Automatic sync tests
