Ethereum core developer Barnabé Monnot has proposed that the network’s block time be slashed in half ahead of the Glamsterdam fork slated for 2026.

In the Ethereum Improvement Proposal (EIP) 7782 discussed on June 21, the developer floated the idea of decreasing block times from 12 seconds to 6 seconds by adjusting the timing of various blockchain operations.

Reduced Block Times Will Up “Service Price”

Monnot said that reducing the amount of time it takes for a new block to get added to the network will increase Ethereum’s “service price,” which refers to the economic value that the blockchain can capture for providing its service as a settlement layer.

According to the proposal, reducing the block times “delivers better user experience, faster Layer 2 interaction, tighter DEX pricing, reduced MEV, and quicker finality.”

Ethereum will always seek to provide the best service at the cheapest sustainable price.

Shorter slot times make the confirmation service better, and so have the potential to raise the service price beyond where it is today, absent any supply increase. But supply increases are… https://t.co/6cOAPTRnps

The proposal also builds on the “healthy scaling” that Monnot said in a June 21 X post will be done by the time the Glamsterdam fork will take place.

“In my view, following this run with a 2x reduction of the slot time would be an amazing option for Ethereum, that should be seriously considered for Glamsterdam,” he added.

New Proposal Comes As Ethereum ETFs Surpass $4B In Cumulative Net Inflows

While developers debate if EIP 7782 should be approved, US spot Ethereum ETFs (exchange-traded funds) managed to surpass $4 billion in cumulative inflows yesterday, according to data from Farside Investors.

That’s after the funds resumed their positive net inflow streak yesterday, with $100.7 million entering the ETFs’ reserves.

BlackRock’s ETHA product, which is the current leader in terms of cumulative net inflows, saw $25.8 million enter its reserves during yesterday’s trading session. However, it was Fidelity’s FETH fund that recorded the highest net inflows of the day after investors poured $60.5 million into the fund.

ETH’s price benefited from the inflows, with CoinMarketCap data showing the altcoin printed a 7% gain in the past 24 hours to trade at $2,411.91 as of 8:02 a.m. EST.
