Vitalik Buterin, co-founder of Ethereum, said that the next significant milestone for Ethereum rollups is achieving fast, sub-hour withdrawal times by adopting validity proof systems. This statement was made on X.
"Amazing to see so many major L2s now at stage 1," said Buterin. "The next goal we should shoot for is, in my view, fast (<1h) withdrawal times, enabled by validity (aka ZK) proof systems. Fast withdrawal times are important because waiting a week to withdraw is simply far too long for people. This is why short term I say once per hour."
According to Buterin in August 2025, six Ethereum rollups—including Optimism and Scroll—have met Stage 1 requirements. These include publishing fraud or validity proofs and achieving open-source sequencer code. These upgrades mark a transition toward decentralization benchmarks set out in Ethereum's rollup-centric roadmap, with Stage 2 reserved for fully autonomous and censorship-resistant systems.
