This paper introduces Circle STARKs, a novel construction for Scalable and Transparent Arguments of Knowledge (STARKs) leveraging a circle curve x2+y2=1x^2+y^2=1x2+y2=1 over a finite field, specifically optimized for the Mersenne prime p=231−1p=2^{31}-1p=231−1. Circle STARKs employ the Fast Fourier Transform (FFT) to enable efficient polynomial interpolation and low-degree testing, providing significant improvements in proof composition and verification. The construction eliminates the need for elliptic curve-based setups and complex algebraic geometry, making it simpler and more accessible. Benchmarks demonstrate a 1.4x speedup compared to traditional STARKs, highlighting its practical efficiency and scalability for cryptographic applications.
Exploring circle STARKs by Vitalik Buterin: vitalik.eth.limo/general/2024/07/23/circlestarks.html
Following the release of the 'Circle STARKs' paper, Vitalik Buterin wrote a blog post 'Exploring circle STARKs'. To describe the concept more simply, circle STARKs are an innovative approach to enhance the efficiency of zk-SNARKs by integrating them with zk-STARKs. The core idea revolves around leveraging the distinct advantages of both protocols to achieve superior performance in zero-knowledge proofs.
The CircleStarks method capitalizes on the succinctness and practical efficiency of zk-SNARKs while incorporating the scalability and transparency of zk-STARKs. This combination is designed to optimize proof generation and verification processes, particularly for complex computational tasks in blockchain environments. By utilizing a circular proof system where STARKs are used to verify the SNARKs, the approach ensures enhanced security and scalability without compromising on performance.
The Sum-Check Protocol over Fields of Small Characteristic by Justin Thaler: people.cs.georgetown.edu/jthaler/small-sumcheck.pdf
Justin Thaler co-authored a paper titled "The Sum-Check Protocol over Fields of Small Characteristic" along with Suyash Bagad and Yuval Domb, where they presented a novel approach to optimizing the prover's implementation in the sum-check protocol. This approach maintains the majority of multiplications within the base field, significantly reducing computational costs. The implications of this research are substantial for modern zk-SNARKs, enhancing their efficiency and scalability by minimizing the computational overhead associated with extension-field multiplications. This advancement is particularly relevant for applications requiring high-performance and low-latency proof generation.
Getting to Know zkMIPS Proving Architecture by Lucas Fraga:
zkm.io/blog/getting-to-know-zkmips-proving-architecture
ZKM Senior Researcher Lucas Fraga wrote a comprehensive article explaining zkMIPS, a zero-knowledge proof system designed by ZKM to verify the correct execution of MIPS programs. This article provides an in-depth analysis of the zkMIPS architecture and elaborates on the verification process, including the division of the program into segments, the use of STARK and PLONK proofs, and a potential Groth16 proof for on-chain verification.
ZKM released an important new paper - ‘zkMIPS: A High-Level Specification’ - which provides a comprehensive overview of how zkMIPS (the first zkVM to support the MIPS instruction set and to support Golang) compiles a program into a succinct proof. It details the high-level specifics of the proving routine, including how general-purpose registers, memory states, and instruction are managed, as well as offering a detailed explanation of how computation steps are transformed into polynomial forms, which is essential for creating succinct proofs. This involves encoding the computation trace as polynomials, ensuring efficient verification through arithmetization, and the use of interactive oracle proofs (IOPs) like the STARKs and LogUp used to efficiently verify polynomial properties: whitepaper.zkm.io/new_zkMIPS_white_paper.pdf
ZKM also launched their highly awaited proving service, aimed at eliminating the hardware constraints when working with their zkMIPS (currently in Testnet). The service is in a developmental phase and thorough testing is necessary before it can be fully integrated into production environments, to ensure that it adheres to security and performance benchmarks. Those interested in accessing the proving service to develop POC applications must apply through ZKM’s application portal: zkm.io/apply.
