An Ethereum developer has issued a proposal that implies chopping the community’s block time in half — from 12 seconds to 6 seconds — with the intention of bettering transaction affirmation time and consumer expertise.
Ethereum Enchancment Proposal 7782, mentioned on June 21 by core developer Barnabé Monnot, suggests chopping the slot time — how typically new blocks are created — to 6 seconds by adjusting the timing of varied blockchain operations.
“Shorter slot instances make the affirmation service higher, and so have the potential to boost the service value past the place it’s immediately,” Monnot defined.
Ethereum’s “service value” refers back to the financial worth that the community can seize for offering its core service as a settlement and affirmation layer.
The proposal, initially created in October 2024, is slated for inclusion within the Glamsterdam replace scheduled in late 2026. “By then, we could have achieved a variety of wholesome scaling” and certain reached blocks with thrice the present gasoline restrict and eight instances the blob provide, he added.
Advantages of sooner Ethereum slots
The staff at Ethereum staking protocol Everstake defined on Monday that new blocks might be proposed twice as typically, rushing up the community and offering a number of advantages.
Shorter slot instances imply sooner transaction inclusion, which might enhance the consumer expertise with a extra responsive chain.
Wallets would show brisker information following transaction inclusion, and onchain information would replace extra ceaselessly. This might lead to smoother experiences throughout wallets, DApps, and layer-2 networks.
It will additionally make it tougher for anybody to censor transactions since there are extra block producers per minute.
DeFi and charge enhancements
There would even be a number of benefits for buying and selling and decentralized finance, corresponding to sooner value updates on decentralized exchanges and lowered losses as a consequence of arbitrage merchants who exploit value variations.

Buying and selling charges would come down as markets turn out to be extra environment friendly, and there could be extra liquidity in automated market makers, Monnot mentioned.
“Quicker slots result in extra liquidity, which suggests decrease buying and selling charges for customers and elevated community results for Ethereum.”
Nonetheless, there might be some tradeoffs, corresponding to impacts on slower or poorly linked validators, which can battle with the tighter timing necessities.
There is also greater bandwidth calls for from extra frequent consensus messages and a higher potential for community congestion throughout peak utilization durations. It will additionally want in depth testing to keep away from community instability and breaking good contracts.
Shortening subslot timings
EIP-7782 proposes changes to a few key subslot timings: block proposal time would go from 4 seconds to a few, attestation time would fall from 4 seconds to 1.5 seconds, and aggregation time would drop from 4 seconds to 1.5 seconds, shaving six seconds general.
Shortening the subslots means there’s much less time to carry out every obligation, mentioned Monnot.
“In my opinion, following this run with a 2x discount of the slot time could be an incredible possibility for Ethereum, which ought to be significantly thought-about for Glamsterdam,” he concluded.
The Glamsterdam replace remains to be in early design phases and focuses on gasoline optimizations and protocol-level effectivity enhancements, basically making Ethereum sooner and cheaper to make use of.
