EthPandaOps Simulates Fast Confirmation Rule
The Fast Confirmation Rule is a feature that allows consensus clients to confirm transactions in a single slot.
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.

EthPandaOps Validator Report Tool
A new page on The Lab that lets users pinpoint validator performance issues down to the slot level.
EthPandaOps, the Ethereum DevOps team that tests protocol upgrades, added a Validator Report page to The Lab, its performance tool for Ethereum validators. Users can paste in validator indices, set a date range, and navigate time and slot ranges to pinpoint when and where performance degraded.
The Validator Report surfaces missed proposals, head-vote drops, and attestation delays. The tool helps discover issues that are invisible at the aggregate level but can be resolved to specific slots.
Validator Report URLs are shareable and preserve state down to the slot level. The tool also features a markdown export function.
The Validator Report is available at lab.ethpandaops.io.
