May 14, 2025

Infrastructure

Gateway​

• There was an issue on Friday that caused Gnosis Pay transactions to get rejected

  • Erigon and Nethermind had diverging results in pending transaction counts

  • That’s a design flaw in Gnosis Pay tbh

• Working on a feature to choose which clients will serve requests on Gateway

  • ETA early summe

Innovation

Shutter​

• Fixed some issues and contacted the keypers to update

  • Some issues in the dht libp2p library

  • Some keyper were offline

Testing

Hive​

• No updates

Ethereum Test​

• No updates

Ethereum/Test​

• No updates

Client updates

EL​

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

  • P2p layer based on libp2p

Reth​

• Upgraded Reth upstream to 1.3.12 with minor refactors

Pectra​

• Testing to do
