Scroll stated Monday it has change into the primary Ethereum Layer 2 utilizing zero-knowledge proofs to achieve 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 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 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 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 consumer actions.
Rollups usually begin at Stage 0 with full staff management, transfer to Stage 1 the place good 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 an enormous drawback for instruments like Scroll.
They should create proofs for every group of actions, however these proofs might solely be so large. If a consumer sends a large motion, it might find yourself disrupting the entire system.
Working with Axiom—a undertaking that helps good contracts confirm previous blockchain knowledge—Scroll constructed a brand new software 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 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 staff known as the Safety Council, which mandates strict guidelines.
Not less than 9 members should comply with do something, and at the very least 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 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 “wanting ahead” to Stage 2, which might restrict what anybody group can do in an emergency, even the Safety Council.
