Ethereum draft aims to cut transaction finality to four minutes

Ethereum researchers filed a draft on October 21 to cut the time a transaction takes to become final, from about 16 minutes to roughly four. Faster finality could make moving money between blockchains cheaper. The plan is only a first step.

Five people wrote it: Francesco D'Amato, Roberto Saltini, Yann Vonlanthen, Mikhail Kalinin and Ben Edgington, who coordinates Ethereum's fast-finality research. Its label is EIP-8453, or Decoupled Consensus. CoinDesk reported the filing on October 22. On GitHub, Edgington wrote that many parts remain undecided.

What the draft would change

Right now, Ethereum validators cast a single vote that does two jobs at once. It picks the current head of the chain, and it locks in older blocks as final. The draft would split that into two separate votes.

Validators are the stakers who secure the network and, through liquid staking and restaking, earn rewards for doing so. Its authors call the split decoupling. In their words, the design decouples "available chain head votes from finality attestations." Pull the two apart, they argue, and the network can lock in blocks sooner.

Three goals sit behind the design. The first is fork-choice security, the logic that settles which version of the chain is correct when validators briefly disagree. The second is cutting the time to finality. The third is making a future move to quantum-resistant signatures easier, a change Ethereum will eventually need to guard against more powerful computers.

CoinDesk reported the target as a cut from about 16 minutes to roughly four, a fourfold improvement. The draft text itself does not list a finality time. Edgington wrote that the team was "primarily just looking for an EIP number assignment at this point," and that "many aspects remain TBD."

Why a few minutes of waiting costs money

Finality is the point where a transaction can no longer be reversed. Until then, a service that moves your money has to assume it might be undone, so it keeps its own funds parked to cover the gap. The longer finality takes, the more cash sits idle.

CoinDesk gave a worked example. A service fronting $1 million an hour would have about $267,000 tied up while it waits 16 minutes for settlement. At four minutes, that drops to about $67,000. The freed cash can be reused, which lowers the cost of each transfer.

That payoff shows up most in services that shuttle money across chains. A bridge or a transfer app often pays out on one side before the other side is final, covering the gap from its own balance. Banks are testing the same rails: JPMorgan recently brought its JPM Coin deposit token to Ethereum mainnet. Shorter finality means a provider can recycle its balance faster and serve more customers with the same capital.

Think of a wire that clears overnight versus one that clears in an hour. The faster it clears, the less money the bank has to hold against it. Circle's fast transfer route out of Ethereum already charges 0.01 percent, or $1 on a $10,000 move, before network and app fees, CoinDesk said.

How early this really is

The draft is at the very start of Ethereum's process, not the end. It has no activation date. The voting timings are not set. Nor are the penalties for validators who break the rules, and parts of the security analysis are still open.

Ethereum has floated faster finality before. A February 2026 roadmap aimed to bring settlement down toward seconds later this decade, with a headline date of 2029. Those targets slip. A draft that asks for a number is a long way from code running on the network.

Rival chains are further along on paper. Solana's Alpenglow upgrade targets finality near 150 milliseconds. Ethereum's draft would still leave it minutes behind, even if it ships. Nothing is final yet.

What to watch

Next comes a formal EIP number and a public discussion thread, which the team said was the immediate goal. After that come the harder questions: the exact voting schedule, the penalties, and a full security review. None of that has a date.

Watch whether other researchers back the split-vote design or pick it apart. Watch, too, whether the Ethereum Foundation folds it into a named upgrade. Until one of those happens, the four-minute figure is a goal on paper, not a change you can plan around.
