First zk-rollup with Stage 1 confirmed: What it is and why it matters

Scroll has become the first zk-Rollup to achieve Stage 1 status with its Euclid upgrade, which was recently approved through Scroll governance. The upgrade adds a permissionless sequencer mode that keeps the network live if the sequencer fails or misbehaves, and it enforces inclusion of Layer 1 user transactions. The article says Scroll's zk proof system was already fully functional, and that a move to a general-purpose zkVM called OpenVM, co-built with @axiom_xyz, enables continuations so that large or forced transactions take longer to prove rather than breaking the rollup. The Security Council has 12 members with a 75% quorum requirement, and upgrades carry a 3-day timelock.
