Scroll mentioned Monday it has develop into the primary Ethereum Layer 2 utilizing zero-knowledge proofs to succeed in a crucial improvement stage, permitting customers to publish transactions with out counting on a central operator.

In a publish to X, Scroll touted its advances in safety, scalability, and decentralization after claiming the challenge had reached “Stage 1” in its improvement.

“Whereas Scroll has all the time had a completely practical zk proof system, customers beforehand needed to belief the centralized sequencer to keep away from censorship or downtime,” it mentioned. “That’s not the case.”

Scroll used to require customers to belief a central system to course of their transactions with out blocking or delays—now, even when that system fails or censors, transactions can nonetheless undergo, in accordance with the challenge.

Scroll’s Euclid improve, which customers voted to approve earlier this month, retains the system operating even when the first operator stops or tries to dam consumer actions.

Rollups usually begin at Stage 0 with full workforce management, transfer to Stage 1 the place sensible contracts take over however a security council can step in, and attain Stage 2 when the system runs fully on code with no central authority.

If the operator blocks a consumer or shuts down, the transaction can nonetheless be included and despatched to Ethereum. This fixes a giant drawback for instruments like Scroll.

They should create proofs for every group of actions, however these proofs might solely be so massive. If a consumer sends a large motion, it might find yourself disrupting the entire system.

Working with Axiom—a challenge that helps sensible contracts confirm previous blockchain information—Scroll constructed a brand new instrument known as OpenVM, which breaks down massive actions into smaller, provable items.

As a substitute of being liable to failing, bigger proofs might “simply take longer to show,” Scroll defined in its publish.

To maintain customers protected, all system adjustments have to be voted on after which wait three days earlier than they apply. This offers customers time to exit if they do not just like the adjustments.

The Euclid replace establishes a 12-person security workforce known as the Safety Council, which mandates strict guidelines.

No less than 9 members should conform to do something, and a minimum of seven of them should not work for Scroll. Solely two council members from Scroll are permitted to sit down on the council.

Regardless of the enhancements, Scroll has had its justifiable share of issues. Launched in 2023, it went to market later than rivals like zkSync Period and Polygon zkEVM.

Nonetheless, Scroll says it is now “trying ahead” to Stage 2, which might restrict what anyone group can do in an emergency, even the Safety Council.
