Testing

Hive​

• Rebase on upstream

• Removed some pre-merge related code from the simulator because the TTD was removed from Geth and Erigon clients

  • Because only Gnosis Chain uses them

Client updates

EL​

Nethermind​

• No major updates

• Preparing for Hoodi: monitoring, etc

  • Deprecating Erigon starting on May 1, 2025

  • Ideally 64 GB of RAM, but should likely run fine with 32 GB

    • With Caplin integrated
    • Erigon is running a mainnet validator with 32 GB and the performance seems to be acceptable
      • Some corner cases are still being ironed out
    • Andrew will profile memory consumption for GC
    • Might even work with 16 GB with Caplin, but to be verified

  • Shutter support is pretty much ready

    • Managed to build a few Shutterized blocks
    • Might include it in the 3.1 or 3.2 Erigon release

• Will implement new Hive and RPC tests

• Testing the Shutter integration on Shutter

Innovation

Shutter​

• Small issue in Chiado fork, updating to new libp2p version. Unrelated to Gnosis impl, should be ok by this week.
  • Testing on-going

Testing

Hive​

• Tried to run generated tests, but Hive doesn’t support Gnosis. Need to adjust to make it compatible. Probably a Genesis issue

Ethereum/tests​

• Ethereum/tests
  • No updates, not yet merged

Client updates

EL​

Nethermind​

• Spent time on Holesky recovery, Chiado all good, pending testing results. One issue, which may not affect Chiado. Asked input to Gnosis devops about CPU info.

• Reviewing Pectra post audit, but nothing important found yet

• Working on history expiry

Erigon​

• New release 3.0.0-rc.3 small fix for syncing from scratch post-pectra. One small issue in RPC for estimateGas.

Geth​

• No updates, not ready yet for Pectra.

Reth​

• Made compatible with Chiado, synced up until Cancun stopping before Pectra. Stuck on a post-execution issue.

• Second mainnet sync on-going

• Attempt to be ready by Pectra

CL​

• PR to baked in Chiado, didn’t make it on time for the fork. But for the mainnet release they will be released

Pectra​

• Fork date on Ethereum is unclear at the moment.

• Geth network share appears negligible at the moment.

• We commit to schedule Gnosis date whenever Ethereum schedules, choosing a date that’s a few days earlier. Temptative date of April 1st is dropped.

• DAppNode packages ownership: we should claim ownership of those

  • Nethermind: In their CI already
  • Erigon: Gnosis should CI it
  • Geth: Gnosis should CI it
  • Reth: Gnosis should CI it
  • Lighthouse: Gnosis should CI it
  • Teku: ?, maybe Gnosis should CI it
  • Nimbus: ?, wrapping the release anyway. Gnosis should CI it
  • Lodestar: In their CI, Nico owns it

Research​

• History expiry in Chiado: activation date?
  • Geth may not be ready, but we will keep at least one node able to serve history.
  • Reth already starts from merge state, need to look into support

Erigon​

• Prepared releases for the Sepolia issue 3.0.0-rc2, and 2.61.3
  • Same release for Chiado

Geth​

• Not present

Reth​

• Pushed Pectra related changes for Chiado

CL​

Pectra​

• Sepolia issue
  • Reproduced on devnet 2 and would appear on Chiado as well
  • The chain would still be progressing but with empty blocks as long as the buggy transaction stays in the mempool
  • We need to upgrade all the Chiado nodes

Research​

• Testing

  • We should test important contract upgrades (namely the deposit contract) in a shadow fork. Had we not caught the issue on Sepolia, we would have instantly broken the chain with a very basic setImplementation call on the deposit contract.

• Marc’s encrypted mempool research

  • Deb needs a reference to compare his implementation with and is having some issues with Nethermind for this. Will debug on Gnosis QA

CL​

Pectra​

• Check the timestamps for Chiado and Mainnet

  • Nethermind’s automated tests checked the epoch boundaries and that test passed
    • Will still check manually

• Erigon will check

  • The timestamp has to match the slot number
  • The epoch boundary ideally should be checked as well

• Max blob count

  • https://github.com/gnosischain/specs/issues/32
  • On the devnet, Milen had to update some configs for Caplin to work
    • Might be related to the blob count
    • Milen will check what was actually changed, will discuss offline
  • Lion is very confident that going from 6 to 2 max blob is fine

• Blob base fee update fraction

  • Remains unchanged
  • Already documented in the PR on the spec repo

• Holesky failure

  • What if this happens on mainnet?
    • We canonicalize the wrong chain
      • Some deposits will not get counted
      • We have to implement custom rules
    • We slash the wrong chain
  • In any case we need better tools to potentially recover a broken chain if this happens on mainnet
  • Could a shadowfork catch this?
    • In this case not
  • Is it possible to add tests for this type of issue?
    • At the moment there’s nothing universal
    • Client specific

Research​

• Era import / export
  • We’ll work on it after Pectra
  • There’s a tentative consensus around dropping pre-merge history after May 1st
