First production-ready network, Lagrange announced the launch of its Infinite Proving Layer, extending its ZK Prover Network to facilitate proof generation for ZK rollups. This builds on Lagrange’s existing offerings, including the ZK Coprocessor and State Committee.
With this new addition, Lagrange now enables proof generation for a wide range of applications—covering rollups, decentralized applications, coprocessors, and interoperability. The Infinite Proving Layer allows for the generation of proofs at the internet scale, supporting the idea that everything can be proven. This expansion of the ZK Prover Network is designed to address challenges faced by rollups and promote the adoption and utility of zero-knowledge technology.
Initially, Lagrange will provide proof generation for AltLayer and Caldera, two prominent rollup-as-a-service platforms. Soon, Lagrange will also support proof generation for well-known ZK rollup frameworks, such as ZKsync, Polygon CDK, and Scroll’s zkEVM stack.

Key Features Of Lagrange’s ZK Prover Network
Lagrange’s design is modular, allowing it to support multiple independent subnetworks, each with dedicated bandwidth. These subnetworks collectively form a “prover network of prover networks.” This modular structure enables any blockchain, rollup, or application to connect via customizable standards, providing developers with the flexibility to scale without encountering bottlenecks or I/O limitations. Essentially, Lagrange’s ZK Prover Network facilitates the generation of dynamic, infinitely scalable proofs for a wide range of use cases, including large-scale rollup ecosystems.
The architecture of the ZK Prover Network uniquely enables it to handle the scale and complexity of proof generation required for large rollup ecosystems. By utilizing a modular network of subnetworks, Lagrange ensures that any blockchain, rollup, or application can access the proving resources it needs without encountering bottlenecks or central gatekeeping.
Each subnetwork is allocated dedicated bandwidth, supporting diverse proving demands and allowing Lagrange to efficiently power even the largest rollup ecosystems. Additionally, the Lagrange ZK Prover Network supports a range of heterogeneous proving needs, both across the entire network and within each subnetwork. This includes compatibility with different proof systems, such as Boojum, Plonky3, or Plonky2, while maintaining standardized and high-performance proof generation. This adaptability ensures the system can scale to meet ecosystem requirements while allowing provers to specialize and operate efficiently.
Currently, the Lagrange ZK Prover Network includes over 85 top-tier institutional operators on EigenLayer, each running multiple provers to support proof generation. These operators commit to delivering proofs within specific timeframes, ensuring the continuous availability of proofs from the network. Cost efficiency is maintained through the use of bare-metal instances, economies of scale, and Lagrange’s Double Auction Resource Allocation (DARA) mechanism in the prover marketplace. A key challenge of working with ZK technology is managing the complexities of a distributed proving system, but Lagrange simplifies this by handling the details and offering a unified interface for proof generation requests. By integrating with Lagrange’s network, partners can easily outsource proof generation, allowing them to focus on their core business while Lagrange manages the underlying infrastructure.
