An Ethereum developer has issued a proposal that means reducing the community’s block time in half — from 12 seconds to 6 seconds — with the purpose of enhancing transaction affirmation time and person expertise.
Ethereum Enchancment Proposal 7782, mentioned on June 21 by core developer Barnabé Monnot, suggests reducing the slot time — how usually 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 worth past the place it’s right now,” Monnot defined.
Ethereum’s “service worth” 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 can have performed numerous wholesome scaling” and certain reached blocks with thrice the present gasoline restrict and eight instances the blob provide, he added.
Advantages of quicker Ethereum slots
The workforce at Ethereum staking protocol Everstake defined on Monday that new blocks could possibly be proposed twice as usually, dashing up the community and offering a number of advantages.
Shorter slot instances imply quicker transaction inclusion, which might enhance the person expertise with a extra responsive chain.
Wallets would show brisker knowledge following transaction inclusion, and onchain knowledge would replace extra incessantly. This is able to lead to smoother experiences throughout wallets, DApps, and layer-2 networks.
It might 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, reminiscent of quicker worth updates on decentralized exchanges and diminished losses attributable to arbitrage merchants who exploit worth variations.

Buying and selling charges would come down as markets grow to be extra environment friendly, and there can be extra liquidity in automated market makers, Monnot stated.
“Sooner slots result in extra liquidity, which implies decrease buying and selling charges for customers and elevated community results for Ethereum.”
Nevertheless, there could possibly be some tradeoffs, reminiscent of impacts on slower or poorly linked validators, which can battle with the tighter timing necessities.
There may be larger bandwidth calls for from extra frequent consensus messages and a larger potential for community congestion throughout peak utilization intervals. It might additionally want in depth 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, stated Monnot.
“For my part, following this run with a 2x discount of the slot time can be a tremendous choice for Ethereum, which ought to be severely thought-about for Glamsterdam,” he concluded.
The Glamsterdam replace continues to be in early design levels and focuses on gasoline optimizations and protocol-level effectivity enhancements, basically making Ethereum quicker and cheaper to make use of.
