An Ethereum developer has issued a proposal to chop the community’s block time in half — from 12 seconds to 6 seconds — in time for the Glamsterdam replace in 2026.
Ethereum Enchancment Proposal 7782, discussed on June 21 by core developer Barnabé Monnot, suggests chopping the slot time — how usually new blocks are created — to 6 seconds by adjusting the timing of assorted blockchain operations, with the intention of enhancing transaction affirmation time and person expertise.
“Shorter slot occasions make the affirmation service higher, and so have the potential to boost the service value past the place it’s at present,” Monnot explained.
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 developer seeks the proposal, initially created in October 2024, to be included within the Glamsterdam replace scheduled in late 2026.
“By then, we could have accomplished plenty of wholesome scaling” and certain reached blocks with thrice the present fuel restrict and eight occasions the blob supply, he added.
Advantages of quicker Ethereum slots
The group at Ethereum staking protocol Everstake defined on Monday that new blocks may very well be proposed twice as usually, dashing up the community and offering a number of advantages.
Shorter slot occasions imply quicker transaction inclusion, which might enhance the person expertise with a extra responsive chain.
Wallets would show more energizing knowledge following transaction inclusion, and onchain knowledge would replace extra often. This may lead to smoother experiences throughout wallets, DApps, and layer-2 networks.
It might additionally make it more durable for anybody to censor transactions since there are extra block producers per minute.
DeFi and payment enhancements
There would even be a number of benefits for buying and selling and decentralized finance, equivalent to quicker value updates on decentralized exchanges and diminished losses attributable to arbitrage merchants who exploit value variations.

Buying and selling charges would come down as markets turn out to be extra environment friendly, and there can 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 may very well be some tradeoffs, equivalent to impacts on slower or poorly linked validators, which can wrestle with the tighter timing necessities.
There may be increased bandwidth calls for from extra frequent consensus messages and a better potential for community congestion throughout peak utilization durations. It might additionally want intensive testing to keep away from community instability and breaking sensible 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 can be an incredible choice for Ethereum, which needs to be critically thought of for Glamsterdam,” he concluded.
The Glamsterdam update remains to be in early design levels and focuses on fuel optimizations and protocol-level effectivity enhancements, basically making Ethereum quicker and cheaper to make use of.
