# Ethereum Researchers Propose Slashing Finality Times to Four Minutes

A new draft by Ben Edgington and core researchers decouples validator votes to accelerate settlement and lower bridge capital costs.

## At a glance

- **What happened:** Ethereum researchers submitted a draft proposal to lower network settlement finality from approximately 16 minutes to four minutes.
- **Why it matters:** Faster finality reduces the collateral and idle liquidity cross-chain bridges must hold while waiting for transactions to become irreversible.
- **Who is affected:** Ethereum validators, cross-chain bridge providers, and asset issuers such as Circle.
- **What's next:** The proposal requires the assignment of an official proposal number and technical resolution of voting parameters and penalty structures.
- **Status:** proposed
- **Primary source:** [ETH news: Ethereum’s four-minute settlement plan could lower the cost of moving crypto](https://www.coindesk.com/tech/2026/10/22/ethereum-s-four-minute-settlement-plan-could-lower-the-cost-of-moving-crypto) — coindesk.com

## Key points

- Ethereum researchers proposed reducing network finality delays from 16 minutes to roughly four minutes.
- The draft separates validator votes for block selection and finality, laying groundwork for future quantum-resistant signatures.
- Shorter settlement would lower bridge capital locks from $267,000 to $67,000 for services moving $1 million per hour.

## Editorial remark

- **Context:** Ethereum currently couples block creation with finality attestation, requiring two entire validator voting rounds and creating a 16-minute confirmation lag.
- **Impact:** Cross-chain transfer services and stablecoin issuers like Circle could significantly reduce idle liquidity requirements and in-flight capital limits.
- **Watch:** Assignment of a formal Ethereum Improvement Proposal (EIP) number and technical updates resolving validator penalty rules and voting timing.

Ethereum researchers have submitted a draft proposal to reduce the blockchain's transaction finality window from roughly 16 minutes to approximately four minutes [1]. The document, filed on Wednesday by fast-finality research coordinator Ben Edgington alongside Francesco D'Amato, Roberto Saltini, Yann Vonlanthen, and Mikhail Kalinin, targets a fourfold reduction in the time required for transactions to become irreversible [1]. The draft design remains incomplete and lacks a scheduled activation date [1].

Under Ethereum's existing consensus architecture, validators cast a single vote that concurrently selects the subsequent block and confirms the finality of earlier blocks [1]. Achieving finality currently requires two complete voting rounds across the validator set [1]. The proposed change decouples these functions by establishing separate votes for block selection and finality locking, permitting network developers to adjust finality speed independently and explore subsequent integration of quantum-resistant cryptographic signatures [1].

## Capital Efficiency and Interoperability

The prolonged settlement delay imposes operational liquidity constraints on cross-chain bridging protocols and asset issuers [1]. Interoperability services that provide instant cross-chain payouts must supply liquidity on destination chains until the originating Ethereum transaction secures irreversible confirmation [1]. Ethereum Foundation research indicates that an intermediary underwriting $1 million hourly holds approximately $267,000 in transit under the 16-minute window, a requirement that would fall to about $67,000 under a four-minute settlement schedule [1]. Issuers such as Circle currently charge 0.01% for accelerated routes off Ethereum while capping total in-flight transfer volumes [1].

The initiative comes amid broader efforts to optimize the primary network, following earlier discussions outlining long-term base-layer enhancements in the [Ethereum Foundation's roadmap through Glamsterdam](https://basisdesk.news/news/ethereum-foundation-l1-gas-costs-roadmap-glamsterdam) [1]. Edgington noted that several components of the draft—including voting timings, penalty parameters, and security models—remain under evaluation as researchers seek a formal proposal number to introduce the measure into Ethereum's standardized upgrade track [1].
