What if Ethereum blocks came twice as fast?

EIP-7782 proposes to cut slot time from 12s → 6s as a headliner feature of the upcoming Glamsterdam upgrade.

Let’s unpack what this means for the future of network👇

Proposed by Barnabé Monnot, EIP-7782 suggests reducing Ethereum’s slot time to just 6 seconds.

That means new blocks could be proposed twice as often, speeding up the network without changing the fork choice rule.

Why it matters?

Shorter slot times mean:

• Faster transaction inclusion.
• Onchain data updates more frequently.
• Smoother UX across wallets, Dapps and L2s.

Who benefits?

→ Cross-chain apps: lower latency.
→ Users: quicker transaction confirmation.
→ Rollups: tighter synchronization with L1.
→ DEXs: reduced arbitrage risk.

What changes technically?

• Clients need to support both 12s and 6s slots.
• Some infra like explorers, dashboards need to adapt to variable timing.

EIP-7782 reframes Ethereum as a confirmation engine.

Monnot argues it’s technically feasible and worth making a headline feature of Glamsterdam.

What do you think about that, guys?
