Scroll stated Monday it has grow to be the primary Ethereum Layer 2 utilizing zero-knowledge proofs to achieve a essential growth stage, permitting customers to submit transactions with out counting on a central operator.
In a submit to X, Scroll touted its advances in safety, scalability, and decentralization after claiming the undertaking had reached “Stage 1” in its growth.
“Whereas Scroll has all the time had a totally purposeful zk proof system, customers beforehand needed to belief the centralized sequencer to keep away from censorship or downtime,” it stated. “That’s now 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 response to the undertaking.
Scroll’s Euclid improve, which customers voted to approve earlier this month, retains the system working even when the first operator stops or tries to dam person actions.
Rollups sometimes 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 person 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 huge. If a person sends a large motion, it might find yourself disrupting the entire system.
Working with Axiom—a undertaking that helps sensible contracts confirm previous blockchain knowledge—Scroll constructed a brand new device known as OpenVM, which breaks down massive actions into smaller, provable items.
As an alternative of being prone to failing, bigger proofs might “simply take longer to show,” Scroll defined in its submit.
To maintain customers secure, all system adjustments 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 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 no less than 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 opponents 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.
