Ethereum researchers have outlined a proposal to shorten transaction finality from approximately 16 minutes to four minutes, a change that could reduce settlement delays and free up capital used by cross-chain payment providers.

The draft, submitted Wednesday, was developed by Ben Edgington, who coordinates Ethereum’s fast-finality research, alongside Francesco D’Amato, Roberto Saltini, Yann Vonlanthen, and Mikhail Kalinin. The proposal remains in development, with no confirmed implementation date.

On Ethereum, a transaction can be recorded in a block before it reaches finality. Finality is the stage at which validators commit to the blockchain’s transaction history, providing strong protection against reversals under the protocol’s security assumptions.

For cross-chain services, this distinction affects when providers can safely complete transfers and recover funds advanced on another network.

Shorter Finality Could Improve Capital Efficiency

Cross-chain providers often release funds to customers before the original transaction has finalized on Ethereum. They must then wait for confirmation before treating the transfer as fully settled.

A shorter waiting period could reduce the amount of money tied up in these pending transactions.

For example, a provider advancing $1 million per hour would have roughly $267,000 awaiting settlement under a 16-minute finality window. If the delay fell to four minutes, the outstanding amount would drop to approximately $67,000.

That reduction could help providers recycle capital more quickly and potentially lower operating costs.

Circle’s USDC transfer service illustrates how settlement speed can affect pricing. Its fast Ethereum transfer route charges 0.01% of the amount transferred, or $1 for a $10,000 transaction, excluding network and application fees. The standard route carries no Circle transfer fee. Fast transfers are subject to capacity limits, which are replenished as transactions settle.

Ethereum Could Change How Validators Reach Finality

Ethereum’s current validator voting process performs two functions simultaneously: selecting the next block and helping finalize previously recorded blocks.

Finality generally requires two complete rounds of validator voting. The proposed design would separate the two responsibilities into distinct votes, potentially allowing the network to finalize transactions more quickly.

Researchers also suggest that this separation could make future upgrades to quantum-resistant signatures easier to implement. Such changes may become necessary if sufficiently powerful quantum computers threaten the cryptographic systems used today.

However, the proposal still has unresolved technical questions, including voting schedules, penalties, and security considerations.

The Proposal Has No Confirmed Launch Date

Ethereum’s four-minute target would still be slower than Solana’s Alpenglow upgrade, which aims for finality in around 150 milliseconds under normal conditions.

Edgington said the proposal remains at an early stage, with further work needed before its design is settled. The immediate objective is to assign it a formal proposal number and move it into Ethereum’s upgrade-development process.

Until the research progresses further, the four-minute figure remains a proposed goal rather than a confirmed change. If adopted, faster finality could help cross-chain providers reduce settlement exposure, improve capital efficiency, and process transfers more economically.
