Lagrange Introduces the Infinite Proving Layer: Expanding Decentralized Proving to ZK Rollups

Today, Lagrange has expanded its ZK Prover Network to power proof generation for ZK rollups, adding onto Lagrange’s existing ZK Coprocessor and State Committee offerings. With this new addition, Lagrange now unlocks proofs for anything – for rollups, apps, coprocessors and interoperability – as an infinite proving layer that enables anyone to prove everything at internet scale. Previously, Lagrange launched the first production-ready ZK prover network in the industry, operated by top operators including Coinbase, Kraken, OKX and more. Now, Lagrange’s ZK Prover Network is expanding to address key challenges faced by rollups and advance ZK adoption and utility.

Rollups are essential for scaling blockchains; yet, traditional proof generation for ZK rollups relies on centralized systems that pose issues related to censorship resistance, scalability and efficiency. For example, if a rollup relies on a centralized prover deployed on a cloud provider like AWS, any outage experienced by the cloud provider would halt the rollup’s ability to generate validity proofs. To solve this, Lagrange distributes computational tasks across a global network of operators and provides each rollup with decentralized and dedicated proving bandwidth. Lagrange’s ZK Prover Network removes the censorship and liveness risks associated with a single point of failure, enabling thousands of proof requests to be handled simultaneously across a decentralized network of operators (even during high demand).

To start, Lagrange will power proofs for AltLayer and Caldera, two leading rollup-as-a-service ecosystems in the space. Soon, Lagrange will support proof generation for popular ZK rollup stacks, including zkSync, Polygon CDK and Scroll’s zkEVM stack.

Powering Infinitely Scalable, Universal Proving

To understand the power of Lagrange’s ZK Prover Network, it’s helpful to look back at the evolution of the Internet. In the 1970s and early 1980s, pre-Internet networks (or “intranets,” systems used within organizations) typically relied on a limited number of mainframe computers to manage communication. Constrained by centralized processing, this pre-Internet architecture faced severe limitations in handling growing demand. The introduction of the Internet—a vast, open “network of networks”—enabled the use of multiple servers distributed across different locations, dramatically increasing scalability. By distributing workloads among these servers, the Internet could handle exponential growth in data and users without overwhelming any single system. Similarly, Lagrange has designed a decentralized ZK prover network with a modular architecture that allows for dynamic scaling, echoing the Internet’s boundless growth and versatility.

Unlike traditional, monolithic ZK prover networks that rely on single-gateway models, Lagrange's design is modular, supporting multiple independent subnetworks with dedicated bandwidth that collectively form a “prover network of prover networks”. This approach allows any blockchain, rollup, or application to connect through customizable standards and empowers developers to scale without bottlenecks or I/O constraints. In other words, Lagrange’s ZK Prover Network enables dynamic, infinitely scalable proofs for everything, including large-scale rollup ecosystems.

Key Differentiators of Lagrange’s ZK Prover Network

Due to the “network of networks” architecture of Lagrange’s ZK Prover Network, Lagrange is uniquely able to support the sheer scale and complexity of proof generation required for large rollup ecosystems. Here’s how:

1. Modular Subnetworks: By employing a modular network of subnetworks, Lagrange allows any chain, rollup, or application to tap into the proving resources it needs—no bottlenecks, no central gatekeeping. Each subnetwork receives dedicated bandwidth and is capable of supporting varied proving demands, ensuring that Lagrange can flexibly power the largest rollup ecosystems.

2. Customizable Support for Universal Proving: The Lagrange ZK Prover Network supports heterogeneous and diverse proving needs, both across the whole network and within each subnetwork. This includes support for different proof systems, such as Boojum, Plonky3 or Plonky2, in addition to performant and standardized proof generation. This flexibility ensures that the system can scale based on the needs of the ecosystem, but that provers can also specialize and retain efficiency.

3. Proof Liveness & Cost Efficiency: The Lagrange ZK Prover Network currently consists of 85+ of the top institution-grade operators on EigenLayer, who each run multiple provers to support proof generation. Operators commit to producing proofs within a given time period, or risk non-payment, thus ensuring the liveness of proofs from Lagrange’s Network. Cost efficiency is also guaranteed, due to a combination of using bare-metal instances, economies of scale, and Lagrange’s innovative Double Auction Resource Allocation (DARA) mechanism on the prover marketplace.

4. Production-Ready Proving: A core part of working with ZK is handling the many details of managing a distributed proving system. Lagrange’s system abstracts away such complexities by taking care of all of the details and providing a simple and single interface for proof generation requests. By integrating with Lagrange’s ZK Prover Network, Lagrange’s partners can easily outsource  generating the proofs their applications need and spend more time focused on their core business—Lagrange takes care of everything else.

By expanding its proving capabilities to rollups, Lagrange is decentralizing one of the most critical components of blockchain scalability. Now powering proofs for rollups, apps, coprocessors and interoperability, Lagrange enables anyone to prove anything. In the coming weeks, we will be sharing more on the integration of Lagrange’s ZK Prover Network with AltLayer, Caldera and other partners, as well as the specific use cases we are enabling together. Stay tuned!
