Lagrange ZK Prover Network Expands its Market Reach by Partnering with Matter Labs to Power ZKsync

Lagrange, the decentralized ZK Prover Network, has entered a deal with Matter Labs to direct up to 75% of Matter Labs' outsourced proof demand to the Lagrange Prover Network (LPN)

Lagrange, the decentralized ZK Prover Network, has entered an agreement with Matter Labs to direct up to 75% of Matter Labs’ outsourced proof demand to the Lagrange Prover Network (LPN) over the next two years. This partnership marks a pivotal moment in furthering the ZK Stack’s transition to decentralized proof generation, with ZKsync poised to process an unprecedented amount of proving demand on a decentralized network at an unparalleled scale.

Earlier this year, in January 2025, Lagrange successfully deployed a decentralized version of ZKsync’s ZK Stack prover. This integration highlighted the potential of shifting from centralized single-entity solutions to a fully decentralized model for proof generation.

“Every rollup will be a ZK rollup, and that’s the future of Layer 2 scaling,” said Ismael Hishon-Rezaizadeh, Co-Founder & CEO of Lagrange. “ZK rollups offer unmatched scalability, security, and cost efficiency, making them the inevitable choice for next-generation decentralized applications. With this partnership, ZKsync is able to process more of its proving demand on a decentralized network, and the Elastic Network will operate at an unprecedented scale without compromising on decentralization.”

Throughout the last year, Lagrange has been diligently establishing that decentralized proving networks can not only match but also outperform centralized alternatives. The Lagrange Prover Network (LPN) has already demonstrated its capabilities in reducing costs, increasing throughput, and eliminating reliance on single points of centralized failure.

Now, with Matter Labs committing to LPN for a portion of its outsourced proofs, the industry has a clear path forward toward a fully decentralized ZK rollup ecosystem. For ZKsync users, this translates into lower gas fees and faster transactions. And for businesses building on the Elastic Network, it means greater confidence in the performance and liveness of L2s.

“This collaboration further increases the ability of ZKsync’s Elastic Network to scale, and gives ZKsync builders more options for customization,” said Anthony Rose, CTO of Matter Labs, a contributor to ZKsync. “Decentralized proving increases the resilience of the network, relative to a centralized model, and expands the total available hardware that can be used to generate proofs – which is important as network activity increases. By integrating with Lagrange’s infrastructure, we’re also expanding the flexibility and control available to builders, reinforcing ZK Chains as the most powerful and adaptable scaling solution for the future of web3.”

The ZKsync ecosystem, known for its speed and efficiency, is rapidly expanding. It currently boasts nearly 25 ZK stack chains, 300 applications, and 1.3M onchain transactions in the last month alone, according to DappRadar.

Lagrange has already proven it can operate at a massive scale. In addition to ZKsync, rollup-as-a-service platforms, including Caldera and AltLayer, are also benefiting firsthand from Lagrange by relying exclusively on the Lagrange Prover Network for their ecosystems’ proof generation.
