Ethereum Researchers Float Plan to Cut Finality Time by 75 Percent

A new draft called EIP-8453 suggests splitting validator votes in Ethereum so that block selection and final confirmation run on separate schedules. The change could shrink the current 16-minute finality window to roughly four minutes without touching the 12-second block interval.

Payment providers and bridges currently front their own capital while waiting for transactions to become irreversible. Faster finality would free that liquidity sooner and potentially let firms like Circle cut the 0.01% fee they charge for expedited USDC transfers.

The proposal also lays groundwork for post-quantum signature schemes by decoupling the two voting processes. Implementation would still require a consensus-layer hard fork.

Even at four minutes, Ethereum would remain far behind Solana, which activated its Alpenglow upgrade on 21 October to target 150-millisecond finality. Justin Drake’s February roadmap already set an internal goal of reducing finality to just a few seconds by 2029.
