Ethereum’s core developer Barnabé Monnot has come up with a proposal to make ETH faster and more efficient.

The said proposal recommends reducing block creation time from 12 seconds to 6 seconds.

This plan also coincides with Ethereum’s upcoming Glamsterdam upgrade, scheduled for 2026.

Ethereum Improvement Proposal (EIP) 7782, was discussed on June 21 and Monnot highlighted that reducing block times would speed up transaction confirmations, enhance user experience, and make decentralized finance (DeFi) apps more responsive.

“Shorter slot times improve confirmation services and increase Ethereum’s value as a settlement layer.”

Why Do Faster Blocks Matter? 

With faster blocks, new transactions would be added to the blockchain more quickly. This would facilitate: 

  • Faster transaction updates in wallets and DApps
  • Smoother experiences on layer-2 networks
  • More frequent price updates on decentralized exchanges
  • Lower trading fees and improved liquidity in DeFi

It would also make it harder for anyone to censor transactions since more block producers would be active each minute.

To achieve six-second blocks, Monnot’s proposal suggests shortening three critical parts of the block creation process:

  • Block proposal: From 4 seconds to 3 seconds
  • Attestation (validators confirming blocks): From 4 seconds to 1.5 seconds
  • Aggregation (combining validator votes): From 4 seconds to 1.5 seconds

Monnot noted that these changes would cut the slot time in half.
