Lagrange Strikes a Deal with Matter Labs to Direct Up to 75% of Outsourced Proofs
New York, United States, March 20th, 2025, Chainwire
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) over the next two years. This marks a pivotal moment in furthering the ZK Stack’s transition to decentralized proof generation.
In January 2025, Lagrange successfully integrated a decentralized version of ZKsync’s ZK Stack prover, demonstrating that proof generation no longer needs to rely on centralized single-entity solutions. This new partnership cements that progress, enabling ZKsync to process more of its proving demand on a decentralized network, something never before achieved at this scale.
“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 enabled to lead the charge, and the Elastic Network will operate at an unprecedented scale without compromising on decentralization.”
Lagrange has spent the last year establishing that decentralized proving networks can outperform centralized alternatives. The Lagrange Prover Network (LPN) has already reduced costs, increased throughput, and eliminated reliance on single points of centralized failure. Now, with Matter Labs committing to LPN for up to 75% 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. For businesses, this translates to greater confidence in the performance and liveness of L2s on the Elastic Network.
“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 boasts nearly 25 ZK stack chains, 300 applications, and 1.3M onchain transactions in the last month alone (source: DappRadar). Lagrange has proven it can 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 firsthand from Lagrange by relying exclusively on the Lagrange Prover Network for their ecosystems’ proof generation.
Key Takeaways:
- Decentralization – The majority of proof generation for a major rollup will happen entirely via a decentralized network.
- Lower Costs – Decentralized proving significantly reduces operational expenses, lowering users’ gas fees.
- Liveness & Security – LPN’s network of independent provers ensures continuous uptime, resilience, and higher security than centralized alternatives.
- Revenue & Growth – By capturing more of ZKsync’s proving demand, Lagrange unlocks new revenue generation and network expansion opportunities.
