Ethereum developer Barnabé Monnot has proposed a new development to the Ethereum protocol in EIP-7782 that introduces a groundshaking initiative to cut down block time to 6 seconds, a 50% decrease from its current timing of 12 seconds.
This upgrade, dubbed the Glamsterdam upgrade, is slated for 2026, and it will be built on Fusaka, a prior enhancement rolling out. This development incorporates Verkle trees for improved efficiency, and Ethereum is poised for a significant change when implemented.

Under this upgrade, the block proposal subslot timing will be decreased by 1 second, the attestation proposal subslot will decrease from 4 seconds to 1.5 seconds, and the aggregation proposal subslot duration will decrease from 4 seconds to 1.5 seconds, combining to a total deduction of 6 seconds off the current 12-second cycle.
This will result in faster blocks and quicker confirmations, essentially creating a seamless experience for users. It could also translate to tighter arbitrage windows and low fees on the network.
As the crypto community discusses the proposal’s impact, Ethereum aims to solidify its position as the leading smart contract platform with the newly proposed changes, with it potentially setting a new standard in blockchain performance.
