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

Client Team Updates

EL

  • Nethermind:

  • Erigon:

    • Discovered parameter that was causing issues
    • Fixed problem related to OOM, problem for several nodes, incl Gnosis chain
    • An Erigon node is now 700GB with --prune=hrtc, which is around the same size as an archive node
      • Maybe there’s some issue with pruning for Gnosis?
  • Geth:

    • Second branch was able to start syncing this morning
    • Might need some help from Nethermind regarding receipt encoding

Chain Infra

  • Gateway
    • No one present

Hive Tests

  • No update

Devnet

  • Erigon updated the configs
  • We’re not sure if it’s running because Carlos is not present

    • Syncing issues
  • The chain seems to be progressing

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

Nethermind:

  • Working on internal dencun specific things for Gnosis
  • Right now 4844 variables are hardcoded in Nethermind and they’re working on making this configurable
  • A new release candidate is underway, majorly integrating cancun features along with some fixes.

Erigon: No one present

Geth:

  • Not much progress since last week, mostly investigating
  • 2 branches
    • One that extracts the data from the Nethermind DB and creates the DB to use by the next branch
      • Figured out why it was running out of memory: memory leak in the transaction pool, but didn’t spend too much debugging because of the new branch
    • One that is more modern and supports withdrawals, but doesn’t currently sync.
      • Has issues connecting to other nodes in the network.

Chain Infra

Gateway No one present

Hive Tests

  • Fixed the withdrawal issues after merge.
  • Working on the dencun tests.

Devnet

  • The devnet nodes have been stable and the network is finalizing
  • Lighthouse requires the preset to be built in?
  • The blob transaction spammer has some issues, it would be better to try to internal Nethermind tool
  • Running with the min gas per blob preset since Friday
  • Two more parameters need to be updated, and we need to spin up a new devnet with Erigon from the get go

October 4, 2023

EL

  • Nethermind: Working on Shutter No more xdai(_archive) configs in the new Nethermind release (1.21.0) Potential issues in Avado

  • Erigon: The header download functionality is acting up a bit from time to time Somnath is working on it Transaction pool should work on Gnosis but hasn’t gone through extensive testing Same for validating

  • Geth: Was able to sync 1.5m blocks Geth is now running out of memory on the old branch Did a rebase and is cleaning up some code, but that new branch isn’t syncing

Chain Infra

  • Gateway Is running 100% of the RPC traffic of the Gnosis RPC

Dencun

EIP-4844

  • Big block experiment
    • The network suffers from big blocks (we spammed it super cheaply for a 10 - 20 minutes)
    • The head participation went down quite a bit (close to 20%)
  • Min gas price will be 1 gwei to be on the same scale as normal transactions (1 gwei minimal priority fee)
  • Nethermind wrote a tool to spam blobs and it broke a lot of clients
    • These might just have been early implementation bugs
  • EIP-7514

Hive Tests

  • Merged the dencun tests from upstream
  • Will work with Egor to catch up as fast as possible

Devnet

  • We have a Devnet with Nethermind, Teku and Lodestar
    • Lighthouse doesn’t work for custom configs anymore, Carlos is in communication with them
  • There are some issues, probably related to peering
  • Also deployed the blob scanner and spammer

EL

  • Nethermind: Exploring Shutter and waiting for some answers Probably going to release a new version of Nethermind end of this week

  • Erigon: No updates

  • Geth: Found the previous problem thanks to Somnath The contracts weren’t properly imported, but the logic works correctly Was able to sync 145k blocks After this, one transaction has an invalid gas usage (more expensive on geth) https://gnosisscan.io/tx/0x05a1fdb3888007224b13b425e7c2442b3f462919a52f8785b857c15dd255d5d2 Comparing traces as we speak Has to rebuild the current state (~14 hours) Needs access to an S3 bucket in order not to have to sync from scratch constantly Implemented the withdrawal contract to be able to go through the transition once it gets there

Chain Infra

  • Gateway No one present

Dencun

  • Devnets
    • Empty system address? We’ll try to send a few wei to the system account on Chiado first
    • Devnets Carlos is preparing configurations for the devnet Should be ready for end of this week or start of the next one Working on the max churn limit

Hive Tests

Started working on the dencun tests As soon as tests are ready, they’ll be shown in the dashboard https://hive-gno.nethermind.io/ Work on upstreaming will be done after dencun tests are implemented Somnath can help for that Will speak with Egor about adding older Hive tests

Research

  • AuRa contracts Should be cleaned up Jorge was exploring this topic but gave up Marek will ask him about his opinion
  • What about BEACON_ROOTS_ADDRESS? Will we have the same address or a different one? We should be able to create it at the same address Worst case we can just hardcode it in the genesis file (ideally CREATE2 though) Guillaume asked Matt Might rely on a dependency on EF, in which case we can just make the address configurable and deploy it with our own keys
  • Are legacy transactions disabled? Might still be enabled in Erigon, but not in Geth and Nethermind? Andrew will check Geth disabled legacy transactions (without chain id) in the transaction pool, but still accepts them in the block

  • Nethermind: Did some work for the optional fast sync protocol (to fix the eth/66 requirement and enable eth/68) This would be a temporary workaround Might be able to deliver the new layout + snap server before dencun Made contact with Shutter New release planned for next week Will include the RPC fix (Gnosis and Gateway are using custom images right now)

  • Erigon: Root node dump for Guillaume? Somnath is on it and syncing Gnosis mainnet Mostly done with Dencun, probably some small things left Somnath has been working on improving the transaction pool for blob transactions

  • Geth: Tanishq is going to generate traces from the execution of the reward contract to compare them (Nethermind vs Geth) Can’t sync anymore for some reason and is getting a lot of timeouts Waiting for Somnath’s dumps

Chain Infra

  • Gateway No one present

Dencun

  • Devnets
    • We’re going to launch a Gnosis Dencun devnet at the same time as devnet 9
      • So we can get the most features included
      • Probably next week or within 10 days
      • Still some issues, but worse case we can launch a bit later
  • Empty system address
    • Marek thinks that it’s empty
    • Andrew proposes to remove the system address on the first dencun block if it is empty
      • To be more in line with Ethereum
      • Marek needs to think about this
      • The downside is that it makes the logic more complicated
  • System address -> no system address
    • Different AuRa systems that have different properties and the code still needs to be maintained
    • We still have to support it for archive Gnosis
    • Tricky solution: send a few wei to the system account

Hive Tests

No updates Andrew would like to talk about upstreaming to the Ethereum repo We should talk about this when Marcos is back

September 6, 2023

EL

  • Nethermind: Met the Shutter guys There were some questions and answers Asked for priorities

    1. Cancun We want EIP-4844 as soon as possible
    2. Shutter
  • Erigon: No updates

  • Geth: Got some Chiado data but it was missing the code, so waiting for a new dump Requesting more details about the system address being or not being in the state Guillaume will contact Lukasz on Telegram EIP-158 needs to be disabled for system transactions

Chain Infra

  • Gateway No updates

Mainnet

Deposit UI somewhat fixed The previous deposits cache is now kept up to date on every build But we’re still getting RPC issues a lot of the times, making deposits quite painful The RPC error wa actually fixed by Nethermind, but not released There was a custom release for Gateway Auto claim Some sample contracts were written but there’s nothing concrete

Dencun

We should start launching devnets There will be some differences for shadow forks as well We need a copy of the deposit / withdrawals contract, so that the shadow forked network doesn’t have all validators deposited We just have to deploy the deposit contract on Gnosis mainnet Will require some changes in Nethermind and Erigon to support deposit contract swaps

Hive Tests

No updates

Research

  • Big blocks experiment What size should we allocate to 4844? Just parameter changes
  • Cancun: there are definitely some differences
    • 4844 requires eth/68, but we don’t have that because we don’t have snap sync
      • Nethermind has a client for snap sync but doesn’t serve that data
      • Erigon also doesn’t serve the data
      • A clean solution might be to introduce a new way to sync data?
    • System transaction differences between Gnosis and mainnet for 4337
      • Erigon would prefer to do all the system transactions the same way for Gnosis, so use the current concept for Gnosis and a different one for Ethereum
      • There are some downsides
    • Hive tests will have to be different
    • Lion: why not keep the same code as for Ethereum? We already have hacks for AuRa, and we would have to add hacks to the new system transaction way as well

Next week DappCon
