EthPandaOps, the Ethereum DevOps Team, published results from fcr-simulator, a tool that replayed 12 months of Ethereum mainnet beacon chain data through four consensus client implementations of the Fast Confirmation Rule to see how it would have performed in production. The Fast Confirmation Rule is a Ethereum protocol feature that will allow consensus clients to confirm transactions in a single slot (~13 seconds) by using validator attestations.

In the simulation, EthPandaOps found zero false confirmations across 5.15 million slot evaluations and no client ever fast-confirmed a block that turned out non-canonical. Across the 800,000-slot window tested, it found that roughly 96 out of every 100 slots would have been fast-confirmed within 12 seconds.

The simulation was run on four Ethereum clients: Lighthouse, Lodestar, Teku, and Grandine. The Fast Confirm Rule requires no hard fork, only a configuration flag on consensus clients. It's expected to enable roughly 98% faster transaction confirmations for users, compared to Ethereum's current ~13-minute finality.

Ethereum developer Carl Beek announced that May 29th will be his last day at the Ethereum Foundation, becoming the latest in a string of notable departures from the organization. Beek joined the EF at the age of 23 and contributed to some of Ethereum's most significant technical milestones, including the KZG ceremony and early Beacon Chain architecture.

Beek also co-authored EIP-7935 to raise the mainnet gas limit and authored Quick Slots EIP-8198 for reducing slot duration. His departure follows a wave of EF exits since Tomasz Stańczak stepped down in February 2025, including Trent Van Epps, Barnabé Monnot, Tim Beiko, Raúl Kripalani, and Ethereum researcher Julian Ma, who also announced his departure today. Danny Ryan and Dankrad Feist left the EF in 2024 and 2025.
