Lurk | Zk-compute Platform | Crypto Deep Dive

Executive Summary

Lurk represents a versatile zk-compute platform that empowers developers to verify computation outcomes without disclosing the underlying data. This platform simplifies the creation of zk-apps, enhancing accessibility for a wider developer audience. A notable feature of Lurk is its Lurk-lang, a Turing complete programming language meticulously crafted for zk-proofs.

Distinguished from other zero-knowledge languages, Lurk incorporates innovative “folding schemes,” facilitating recursive zero-knowledge proofs and incremental verifiable computation. This approach enables developers to generate zero-knowledge proofs incrementally and in parallel, offering significant advantages for off-chain computing and blockchain scalability. By dividing computation tasks and executing them concurrently, Lurk ensures expedited and more efficient verification of intricate computations.

Lurk facilitates verifiable computation, wherein the accurate execution of Lurk expressions can be proven in zero-knowledge. This capability empowers developers to authenticate computation results while safeguarding sensitive data. Consequently, Lurk holds promise for numerous privacy-sensitive applications, including managing confidential data within decentralized applications.

About the Project

Lurk facilitates verifiable computation, allowing developers to demonstrate the correct execution of Lurk expressions in zero knowledge, thereby validating computation results without exposing sensitive data. This capability renders Lurk instrumental in numerous privacy-sensitive use cases, including securing private data within decentralized applications.

Each Lurk program is endowed with a unique content identifier (CID), streamlining its integration with distributed systems such as InterPlanetary File System (IPFS) and InterPlanetary Linked Data (IPLD). This integration ensures that Lurk-based applications can seamlessly interact with decentralized storage and retrieve pertinent data without relying on conventional centralized databases. The versatility of Lurk extends across various domains, including off-chain computing, blockchain scalability, and zero-knowledge bridging, underscoring its adaptability to diverse scenarios.

Lurk introduces a revolutionary approach to zero-knowledge computations by leveraging folding schemes and implementing Inter-Blockchain Communication (IBC). By constructing verifier smart contracts for these proofs, Lurk initially targets the Ethereum blockchain, paving the way for enhanced privacy and efficiency in decentralized ecosystems.

Utilizing Nova as the primary proving system, Lurk estimates proof verification times ranging from 10 to 30 milliseconds for the smallest circuits, with proving time exhibiting logarithmic growth relative to circuit size and verifier time increasing linearly. Notably, with Nova, verification time is not escalated for proofs of larger computations. Emphasizing minimal circuit size, prover memory/storage, and proof-size/verification-time ratio, Lurk optimizes proof construction while allowing trade-offs tailored to specific use cases. Additionally, by supporting a range of circuit sizes, Lurk enables users to capitalize on GPU, providing for enhanced throughput and efficiency, ensuring flexibility and scalability across diverse applications.
