Ethereum researchers have filed a draft proposal that seeks to reduce the time it takes for transactions on the network to become final from roughly 16 minutes to around four. If adopted, the change could lower some of the working capital costs faced by services that move funds between Ethereum and other blockchains.
The proposal was filed Wednesday by fast-finality research coordinator Ben Edgington alongside Francesco D’Amato, Roberto Saltini, Yann Vonlanthen and Mikhail Kalinin. It is still an early design with no activation date, and key details including voting timings, penalties and parts of the security analysis remain unresolved.
Why finality time matters
On Ethereum, a transaction can appear in a block before the network considers it final, meaning validators have committed not to rewrite it. For services sending funds off Ethereum, that delay affects when they can safely release money on another network.
That waiting period creates a funding burden for firms that provide fast transfers. If a customer sends $10,000 from Ethereum to another chain, a transfer service can release the funds immediately using money it already holds on the destination network, then wait to be repaid once the Ethereum transaction fully settles. Until that happens, the service has $10,000 tied up.
Ethereum Foundation research described that idle capital as a real cost. Under the example in the draft, a service advancing a steady $1 million per hour would have about $267,000 awaiting repayment with a 16-minute delay. Reducing the delay to four minutes would cut that to about $67,000.
How the draft would change validator voting
The current settlement delay is tied to the way Ethereum validators vote. Today, each validator casts a single vote that serves two purposes at the same time: helping choose the next block and helping finalize older blocks. Because a block becomes final only after two full rounds of voting, finality is limited by that shared process.
The draft proposes separating those two functions into distinct votes. In the researchers’ view, that would allow the finalization process to run on a faster schedule, with room for developers to shorten it further over time.
The authors also argue that splitting the votes could make it easier to later introduce quantum-resistant signatures, an upgrade Ethereum would need if quantum computers become capable of breaking the cryptography now in use.
Potential effect on transfer services
The economics of faster settlement are already visible in existing products. Circle, the issuer of the USDC stablecoin, offers a faster route for transfers from Ethereum that currently costs 0.01%, or $1 per $10,000, before network and application charges. Its standard route does not include a Circle transfer fee.
Circle also limits the total value of fast transfers that are still waiting on final settlement. Each time a settlement completes, capacity is freed for additional transfers. A shorter Ethereum finality window could therefore reduce the amount of capital such services must reserve while transactions are still clearing.
What happens next
The filing does not set a launch date and is not yet a finished upgrade plan. Edgington wrote that many aspects remain to be determined and said the immediate goal was to obtain a proposal number, which places the idea into Ethereum’s formal upgrade pipeline.
The four-minute target would still be far slower than some rival systems. Solana, for example, switched on its Alpenglow upgrade on Wednesday with a target finality time of about 150 milliseconds. For Ethereum, the next confirmed step is further design work on the unanswered questions in the draft, including timings, penalties and the remaining security analysis.
