May 28, 2025

Infrastructure

Innovation

Shutter​

• No major updates

• Working on fixing a bug that prevents starting a new keyper because it can’t sync new events

• Last tests on Chiado: 100% inclusion rate

• Keypers are consistently releasing keys on mainnet

Testing

Hive​

• Found some issues in Nethermind master, discovered by Hive

• Already fixed

Ethereum Test​

• No updates

Ethereum/Test​

• Started work with Marcos

Client updates

EL​

Nethermind​

• Question: how are pre-merge ERA1 files for GC different from Ethereum ones? Is there a spec for it?

• Released 1.31.11

  • Fixes small memory leaks

  • Also includes changes unrelated to Gnosis Chain

• Release candidate (v1.32.0)

• New performance improvements around pruning and block building

Erigon​

• Working on Fusaka

Geth​

• No present

Reth​

• Updated the upstream to 1.4.3

• Working on the custom headers for pre-merge

  • Will not implement pre-merge execution, only implement headers and import historical data with ERA1

• Implemented tagged releases and Docker image builds (currently v0.1.0)

• Will investigate implementing snap sync for Reth

  • Reth doesn’t implement snap sync at all at the moment

  • We want to help them implement this if possible

  • For Nethermind it was complicated because

    • The protocol wasn’t super well specified

    • Some assumptions turned out wrong

• Compressed the initial post-merge state for Chiado and GC so that it’s easier to download on initial sync

Fusaka​

• There’s already devnet0 for mainnet, should we already spin some up for Gnosis Chain?

  • Probably not worth it and a waste of time at this point

  • For PeerDAS specifically, because Gnosis Chain has faster block times it could be an issue

    • Would need big devnets for testing though

• Devnet1 should happen in around a week

Nethermind​

• Bigger release soon to come with a bunch of smaller improvements and fixes

Erigon​

• There are Caplin nodes on the network that are still on Deneb and advertising mainnet Electra (ending with 00 instead of 64) as the next fork https://probelab.io/gnosis/dht/2025-19/#next-forks

  • I’m assuming that it’s just nodes that weren’t up to date and where Electra wasn’t scheduled, so doesn’t sound like a big issue

• Validating performance with Caplin seems suboptimal on mainnet (lots more attestation misses)

  • Functionality-wise Caplin is considered stable

  • Some performance optimizations are still coming

  • Validating performance is a priority right now, so we can expect this to improve in the future

• Started working on Fusaka

• Erigon 3.1 should contain Shutter and should be more robust in terms of performance and snapshots, as well as eth_getLogs

• New snapshots will enable faster eth_getLogs

Geth​

• Released 1.15.11, contains a couple of small fixes

• Work necessary to support Shutter

  • Support the encryption to fetch and decrypt transactions from the sequencer contract
