- Scroll has become the first Ethereum Layer 2 using zero-knowledge proofs to reach Stage 1 decentralization, allowing users to exit independently without relying on a central operator.
- The Euclid upgrade introduces censorship resistance, strict governance limits, and a new tool called OpenVM to enhance system reliability.
In a landmark move for Ethereum scalability and user empowerment, Scroll has declared itself the first zero-knowledge (ZK) rollup to achieve “Stage 1” decentralization. With the launch of its Euclid upgrade, Scroll introduces key protocol changes that allow users to exit independently—without relying on a centralized operator.
Previously, Scroll users depended on a central sequencer to post transactions to Ethereum, which left the door open to censorship or downtime. But with Euclid, Scroll eliminates that risk. Now, even if the sequencer fails or actively blocks transactions, users can still get their data onto Ethereum through permissionless channels.

“Scroll has always had a working zk-proof system,” the project said on X. “But users had to trust a centralized sequencer to avoid censorship or downtime. That’s no longer the case.”
The Euclid upgrade brings three major innovations. First, it introduces a user-controlled exit window that ensures people can leave the network safely before any major changes take effect. Second, it empowers a 12-person Security Council with strict governance limits—only two members may come from Scroll, and a supermajority of nine must approve any emergency action. Finally, Scroll now uses a novel tool called OpenVM, built in collaboration with Axiom, to break down large transaction batches into smaller, more manageable proofs. This prevents a single large transaction from disrupting the system.
With these updates, Scroll enters Stage 1 of decentralization, a critical milestone in the rollup roadmap. While still not fully autonomous, Scroll’s protocol now relies more on code and community governance than on its internal team. Stage 2, the final stage, would eliminate centralized fallback mechanisms entirely.
Despite a slower launch compared to competitors like zkSync and Polygon zkEVM, Scroll’s commitment to trustless infrastructure could give it a strong long-term edge.
“We’re looking forward to reaching Stage 2,” Scroll stated, “where no single group—not even the Security Council—can override the system.”
This evolution marks a meaningful shift in how Layer-2 networks are maturing, bringing Ethereum closer to its decentralization ideals.
