Lagrange to Process 75% of Matter Labs' Zero-Knowledge Proofs Over Two Years

According to a press release published on our website, Lagrange and Matter Labs have reached an agreement that will direct up to 75% of Matter Labs' outsourced proof demand to the Lagrange Prover Network over the next two years. The deal was announced on March 20th, 2025, and changes how proof generation will be handled for Zero-Knowledge (ZK) rollups.

In January 2025, Lagrange integrated a decentralized version of ZKsync's ZK Stack prover. This integration demonstrated an alternative to centralized proof generation. With the new agreement, ZKsync will use a decentralized network for a majority of its proving needs.

"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. He added that ZK rollups provide scalability, security, and cost efficiency for decentralized applications.

The Lagrange Prover Network has shown results in cost reduction and throughput improvements compared to previous solutions. According to the companies, this may result in lower gas fees and faster transactions for ZKsync users, while businesses may see improved performance of L2s.

Anthony Rose, CTO of Matter Labs, noted: "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."

According to data from DappRadar, the ZKsync ecosystem currently includes approximately 25 ZK stack chains, 300 applications, and recorded 1.3 million onchain transactions in the past month. Platforms such as Caldera and AltLayer are also using the Lagrange Prover Network for their proof generation.

The agreement has several practical implications:

• Proof generation for a major rollup will operate through a decentralized network
• The approach may lead to reduced operational expenses
• A network of independent provers aims to provide continuous service
• The agreement expands Lagrange's involvement with ZKsync's proving needs

Lagrange has received $17 million in funding from investors including Founders Fund and CMT Digital. The company reports $29 billion in total restaked ETH and has generated 9 million ZK proofs to date.

This development aligns with other major Zero-Knowledge initiatives in the blockchain space. Earlier this month, Hemi Labs launched a $440 million mainnet that connects Bitcoin and Ethereum networks. Founded by early Bitcoin developer Jeff Garzik, the project enables Bitcoin to access Ethereum's programmability while maintaining Bitcoin's security features.

StarkWare, the $8 billion company behind Ethereum Layer 2 solution Starknet, recently created a "Strategic Bitcoin Reserve" while expanding Starknet's Bitcoin capabilities. The company now holds a portion of its treasury in Bitcoin and has introduced features connecting Starknet with Bitcoin's Lightning Network for faster transactions.
