Ethereum Developer Proposes Halving Block Slot Time to 6 Seconds

- Ethereum Improvement Proposal 7782 aims to halve block slot time from 12 seconds to 6 seconds. - The changes promise faster transaction confirmations, enhanced DeFi operations, and improved user experience. On June 24, 2025, Cointelegraph reported that Ethereum’s core developer, Barnabé Monnot, proposed EIP-7782. This proposal aims to halve block slot times from 12 seconds to 6 seconds, a change Monnot intends to improve transaction confirmations and DeFi efficiency. He proposed EIP-7782 for inclusion in the Glamsterdam update, which developers have scheduled for late 2026. Monnot highlighted that the proposed change would increase the network's "service price," which represents the economic value Ethereum garners from its role as a settlement and confirmation layer. Regarding the proposal's history, Monnot initially drafted it in October 2024 and discussed it further on June 21, 2024. Specific changes within EIP-7782 include reducing the block proposal time from 4 seconds to 3 seconds, decreasing attestation time from 4 seconds to 1.5 seconds, and cutting aggregation time from 4 seconds to 1.5 seconds. Implementing EIP-7782 should bring several improvements. It promises more rapid transaction inclusion, which will make the blockchain more responsive. Consequently, wallets and decentralized applications (DApps) will receive more current data. Additionally, the proposal aims to bolster transaction censorship resistance, as a higher number of block producers per minute would make censoring transactions more difficult. Furthermore, within the DeFi sector, the proposal could lead to faster price updates on decentralized exchanges, reduce arbitrage losses, lower trading fees by increasing market efficiency, and improve liquidity in automated market makers. However, the proposal also acknowledges potential drawbacks. For instance, stricter timing demands could challenge validators with slower or less stable internet connections. The increased frequency of consensus messages could also lead to higher bandwidth requirements, potentially causing greater network congestion during peak usage. Therefore, the team must conduct comprehensive testing to prevent network instability and ensure the changes do not negatively impact existing smart contracts. Meanwhile, the Glamsterdam update, where this EIP is proposed for inclusion, will primarily focus on optimizing gas usage and improving protocol-level efficiencies to make the Ethereum network faster and more cost-effective. According to CoinMarketCap on June 24, 2025, Ethereum (ETH) was trading at $2,396.33 as of 04:17 UTC, and its 24-hour trading volume showed a 7.22% increase.
