Scroll stated Monday it has turn into the primary Ethereum Layer 2 utilizing zero-knowledge proofs to succeed in a vital growth stage, permitting customers to put up transactions with out counting on a central operator.
In a put up to X, Scroll touted its advances in safety, scalability, and decentralization after claiming the challenge had reached “Stage 1” in its growth.
“Whereas Scroll has at all times had a completely purposeful zk proof system, customers beforehand needed to belief the centralized sequencer to keep away from censorship or downtime,” it stated. “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 keeping 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 sometimes begin at Stage 0 with full crew 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 solely 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 an enormous downside for instruments like Scroll.
They should create proofs for every group of actions, however these proofs may solely be so large. If a consumer sends a large motion, it may find yourself disrupting the entire system.
Working with Axiom—a challenge that helps sensible contracts confirm previous blockchain knowledge—Scroll constructed a brand new device referred to as OpenVM, which breaks down giant actions into smaller, provable items.
As a substitute of being vulnerable to failing, bigger proofs may “simply take longer to show,” Scroll defined in its put up.
To maintain customers secure, all system modifications have to be voted on after which wait 3 days earlier than they apply. This provides customers time to exit if they do not just like the modifications.
The Euclid replace establishes a 12-person security crew referred to as the Safety Council, which mandates strict guidelines.
At the least 9 members should conform to do something, and no less than seven of them should not work for Scroll. Solely two council members from Scroll are permitted to take a seat on the council.
Regardless of the enhancements, Scroll has had its fair proportion of issues. Launched in 2023, it went to market later than opponents like zkSync Period and Polygon zkEVM.
Nonetheless, Scroll says it is now “wanting ahead” to Stage 2, which might restrict what anyone group can do in an emergency, even the Safety Council.
