Lean Ethereum has reached Devnet5 interop, a major milestone in its effort to make Ethereum's consensus layer quantum-resistant. Ethereum currently uses BLS signatures, which are not post-quantum secure. Lean Ethereum is leveraging quantum-resistant hash-based signatures to address this. The goal is to achieve a PQ signature scheme ready for Ethereum mainnet.

Devnet5 uses leanVM, a ZK-based aggregation layer, to enable entire blocks to carry just one aggregated signature proof instead of many individual signatures. Eight clients are participating in the devnets, with the Lean team progressively scaling validators and subnets to reach production-grade performance.

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.

Ben Edgington, a former Ethereum client developer and current finality researcher at the Ethereum Foundation, published the first edition of a new blog series outlining a practical path to reducing Ethereum's time to finality from roughly 1,000 seconds to under 10 seconds. The core strategy is decoupling, which could alone deliver a meaningful initial speedup.

Currently, finality votes and fork-choice votes are bundled into a single attestation structure, which ties the finality process to the rhythm of individual slots. Separating the two would allow finality to operate on its own timescale, consuming otherwise-idle network bandwidth and removing the slot-length constraint.

Further incremental improvements will be designed to be deployable independently. Edgington notes that we must achieve fast finality without excluding home stakers or reducing validator set diversity. The Ethereum Strawmap places decoupled consensus as a headliner candidate for the I* fork, currently anticipated in late 2027.
