Matter Labs Partners with Lagrange for 75% Proof Demand, Boosting Decentralized ZK Rollups

Lagrange, a decentralized ZK Prover Network, has entered into a significant agreement with Matter Labs. This deal will direct up to 75% of Matter Labs’ outsourced proof demand to the Lagrange Prover Network (LPN) over the next two years. This partnership is a crucial step in transitioning the ZK Stack to decentralized proof generation.

In January 2025, Lagrange successfully integrated a decentralized version of ZKsync’s ZK Stack prover. This integration demonstrated that proof generation no longer requires centralized single-entity solutions. The new partnership with Matter Labs further solidifies this progress, allowing ZKsync to process a significant portion of its proving demand on a decentralized network, a feat not previously achieved at this scale.

Ismael Hishon-Rezaizadeh, Co-Founder & CEO of Lagrange, emphasized the importance of ZK rollups in the future of Layer 2 scaling. He stated that ZK rollups offer unmatched scalability, security, and cost efficiency, making them the inevitable choice for next-generation decentralized applications. With this partnership, ZKsync is positioned to lead the charge in decentralized proof generation, enabling the Elastic Network to operate at an unprecedented scale without compromising decentralization.

Lagrange has spent the past year proving that decentralized proving networks can outperform centralized alternatives. The LPN has already achieved cost reductions, increased throughput, and eliminated reliance on single points of centralized failure. With Matter Labs committing to LPN for up to 75% of its outsourced proofs, the industry now has a clear path toward a fully decentralized ZK rollup ecosystem.

For ZKsync users, this partnership translates into lower gas fees and faster transactions. For businesses, it means greater confidence in the performance and liveness of L2s on the Elastic Network. Anthony Rose, CTO of Matter Labs, highlighted that this collaboration increases the ability of ZKsync’s Elastic Network to scale and provides builders with more options for customization. Decentralized proving enhances the network's resilience and expands the total available hardware for proof generation, which is crucial as network activity increases.

By integrating with Lagrange’s infrastructure, Matter Labs is 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, which includes nearly 25 ZK stack chains, 300 applications, and 1.3 million onchain transactions in the last month, is poised to benefit significantly from this partnership.

Rollup-as-a-service platforms, including Caldera and AltLayer, are also benefiting from Lagrange by relying exclusively on the LPN for their ecosystems’ proof generation. This partnership underscores the potential of decentralized proving networks to revolutionize the blockchain industry by offering lower costs, enhanced security, and greater scalability.
