Ethereum Researchers Propose Reducing Transaction Finality Time to Four Minutes

TL;DR Ethereum researchers proposed EIP-8453 to separate block-selection votes from finality attestations, targeting at least a fourfold reduction from roughly 16 minutes to about four. The draft could lower capital tied up by cross-chain transfer services while improving reorganization resilience and creating flexibility for future post-quantum signatures. The proposal remains unfinished, with timing, penalties and security analysis unresolved, no activation date, and a consensus-layer hard fork required if eventually formally adopted. Ethereum researchers have proposed redesigning the network’s consensus process to cut transaction finality across the network from roughly 16 minutes to about four. The EIP-8453 draft separates block-selection votes from finality attestations. The proposal targets at least a fourfold reduction in finality time, but remains an unfinished draft with no activation date.
