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

Lagrange, a decentralized ZK Prover Network, has entered into a significant partnership with Matter Labs. This agreement will direct up to 75% of Matter Labs’ outsourced proof demand to the Lagrange Prover Network (LPN) over the next two years. This development marks a crucial step in the transition of 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, enabling ZKsync to process a substantial 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, “Every rollup will be a ZK rollup, and that’s the future of Layer 2 scaling. ZK rollups offer unmatched scalability, security, and cost efficiency, making them the inevitable choice for next-generation decentralized applications. With this partnership, ZKsync is enabled to lead the charge, and the Elastic Network will operate at an unprecedented scale without compromising on 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 the benefits of this collaboration, stating, “This collaboration further increases the ability of ZKsync’s Elastic Network to scale, and gives ZKsync builders more options for customization. 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, which includes nearly 25 ZK stack chains, 300 applications, and 1.3 million onchain transactions in the last month, stands to benefit significantly from this partnership. Lagrange has demonstrated its ability to operate at a massive scale, unlocking the next phase of ZK rollup evolution. 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.

Key takeaways from this partnership include the decentralization of proof generation for a major rollup, significant cost reductions, enhanced liveness and security, and new revenue generation and network expansion opportunities for Lagrange. The partnership underscores the growing importance of decentralized proving networks in the blockchain space, positioning Lagrange as a leader in blockchain-based cryptography and decentralized applications that require complex, high-volume data processing.

Lagrange offers decentralized proving to scale any ZK application, rollup, or protocol. By leveraging a decentralized network to generate ZK proofs, Lagrange unlocks significant efficiency, cost savings, and uptime reliability. Its approach enables hyper-parallel proof generation, advancing cross-chain interoperability and supporting complex computations over large datasets. The company has raised over $17 million in funding from investors and is led by a team of academic experts.
