Ethereum researchers have presented a draft aimed at reducing the time it takes for transactions to reach finality from about 16 minutes to four, with the goal of reducing capital tied up in cross-chain transfers.
According to CoinDesk, Ben Edgington, who coordinates the work on faster finality, and other researchers shared the proposal on October 21. The initial goal is to cut by three-quarters the time the network needs before considering a transaction finalized; the design is not yet complete, and there is no date for its implementation.
How could a shorter wait affect transfers?
On Ethereum, a transaction can be included in a block before the network considers it finalized. For services that move funds to another blockchain, the key question is when they can safely make the payment on the other end.
For example, a transfer service can pay a user who sends $10,000 from Ethereum to another network immediately, using its own reserves. The user receives the money within seconds, while the service provider’s $10,000 remains tied up until the transaction on Ethereum is finalized.
According to calculations in Ethereum Foundation research, a service that regularly fronts $1 million an hour has about $267,000 awaiting reimbursement during the 16-minute wait. If the period is reduced to four minutes, that amount falls to about $67,000. The same capital can then be used for new transfers sooner.
This cost is also reflected in fast transfer services today. On Circle’s fast transfer route from Ethereum, USDC issuer Circle charges a fee of 0.01%, or $1 for $10,000; network and application fees are calculated separately. On the standard route, Circle charges no transfer fee. It is not yet clear how much of the savings that faster finality could bring providers would be passed on to users through lower fees.
Ethereum validators’ votes would be split
Under the current system, validators’ single vote contributes both to selecting the next block and to finalizing previous blocks. Finality requires validators to complete two full voting rounds.
The new draft proposes separate votes for these two tasks. This would allow blocks to be finalized on a faster schedule. Researchers say separating the tasks could also make it easier to transition to quantum-resistant signatures in the future.
The target would still lag behind the approximately 150-millisecond finality goal of Solana’s Alpenglow upgrade, which has been activated.
No implementation timeline yet
Some parts of the draft, including vote timing, penalties, and security analysis, are still being worked on. The first step, Edgington said, is to have the proposal assigned a number so the design can be included in Ethereum’s official upgrade process.
