Ethereum proposal, outlined in EIP-7782, aims to reduce block proposals to 3 seconds, attestations to 1.5 seconds, and aggregation to 1.5 seconds.
The changes could halve the time required to finalize each block, down from the current 12-second cycle.
The proposal may be included in Ethereum’s upcoming Glamsterdam upgrade in 2026, but developers caution that not all proposals move forward.
Efforts are ongoing to optimize ETH’s performance without compromising on decentralization or security.
If implemented, the faster slot time could enhance user experience, DApp responsiveness, and Ethereum's competitiveness against faster Layer 1 competitors.
