The workforce behind zkSync Period, an Ethereum-compatible layer-2 zk-rollup, is launching an open-source framework for constructing zk-rollups and layer-3s, which they name “hyperchains,” based mostly on its code.
The idea — known as ZK Stack — is supposed to deal with a subset of builders for whom sovereignty is paramount. Along with being free and open supply, ensuing chains stay customizable whereas sustaining the safety of an Ethereum zk-rollup.
Matter Labs CEO Alex Gluchowski advised Blockworks that no different present answer for builders offers the mix of permissive open-source license — MIT/Apache — and scalability afforded by zero-knowledge proof know-how.
“The creator (you) possesses full rights to the code and enjoys unrestricted autonomy to customize and shape every aspect of the chain,” zkSync stated in a weblog publish. “Hyperchains operate independently, relying solely on Ethereum [mainnet] for their liveness and security.”
A platform to rival the Optimism “superchain” idea is clearly a objective, however one which front-loads the philosophical underpinnings of Matter Labs’ “ZK Credo,” launched on Friday.
“It’s going to be the only alternative — fully open-source alternative — to Optimism’s stack that is available today for anyone to build rollups,” Gluchowski advised Blockworks.
Among the many key options is that the ZK Stack shall be modular and composable. Which means builders will be capable of select amongst a bevy of choices for the sequencer and information availability layers, however with out fragmenting liquidity and customers.
In precept, “a seamless trustless network with low latency and shared liquidity,” will attraction to purposes that don’t require synchronous composability. Quite than having chains be siloed and requiring using often-risky cross-chain bridges, they’ll be capable of execute person actions throughout a “unified liquidity network.”
“If you look at Optimism’s superchains, in order to build a trustless bridge between superchains, the user will have to wait seven days,” Gluchowski stated.
That’s not ok, he reckons.
“The latency has to be down to seconds, maybe minutes, but really, really short for the liquidity on all of those chains and for interoperability of messages between all of those chains to feel seamless to the end users.”
A spokesperson for OP Labs advised Blockworks the OP Stack can mitigate this present shortcoming, noting that the Optimism Basis lately launched a request for proposal on this challenge.
“[The OP Stack’s] modular design should allow operators to swap and add components according to their unique needs,” the spokesperson stated. “An OP Chain operator might opt to use a [zero-knowledge validity proof] rather than a fault proof, for example.”
The ZK Stack can be effectively suited to purposes that profit from customizability, corresponding to a recreation developer that desires to run its personal sequencer, or an application-specific blockchain corresponding to a decentralized alternate which requires tremendous low latency.
It may additionally apply to personal permissioned chains, corresponding to one run by a financial institution, which nonetheless advantages from being related to the remainder of the ecosystem.
Decentralization roadmap
One of many targets of the initiative is group constructing — to draw builders into the zkSync ecosystem.
“We’ve been working on zkSync Era for several years to build the first [zero-knowledge] EVM-driven blockchain,” Gluchowski stated. “And now it’s time to give it over to the community and enable everyone to build their own versions of it.”
This represents a shift in priorities for Matter Labs, to onboard extra unbiased groups to contribute to the event of the community that started with zkSync Period.
In its early months, zkSync Period — which doesn’t but have a local token — has seen a surge in exercise and whole worth locked, in comparison with competing rollups, based on Gracy Chen from crypto alternate Bitget.
Hyperchains can natively help decentralized sequencers utilizing any current consensus algorithm. ZkSync Period itself expects to change away from its presently centralized sequencer to a decentralized possibility, “and will make its code available to the Hyperchain developers,” based on a weblog publish on hyperchains.
The primary hyperchains are anticipated to go dwell later this yr, however builders are inspired to start experimenting, so that when the requisite modifications to zkSync Period are in place, they’ll be capable of simply deploy their personalized chains.
