Space and Time, a decentralized Web3 data service, has made its graphics processing unit (GPU) acceleration framework, known as Blitsar, publicly available for the broader Web3 ecosystem. Blitsar, designed for GPUs, optimizes the performance of zero-knowledge proofs (ZK proofs) by offloading computationally intensive tasks to the GPU. This acceleration framework is particularly beneficial for computationally demanding operations like multi-scalar multiplication, a crucial aspect of ZK proofs. GPUs excel at handling heavy computational workloads and provide efficient memory structures for processing large data sets.
Zero-knowledge proof (ZK-proof) is a cryptographic protocol that enables one party to prove specific information or data to another party without revealing the information itself, ensuring data confidentiality while verifying its accuracy. Space and Time aims to enhance the efficiency of ZK proofs through Blitsar, and the framework is now open to any project seeking performance improvements related to multi-scalar multiplication. Jay White, co-founder and head of research at Space and Time, stated that open-sourcing Blitsar allows for faster and more robust ZK proofs while inviting community contributions.
Space and Time's service offers Structured Query Language (SQL) programming capabilities for smart contract blockchains, leveraging ZK proof technology. The proprietary SQL ZK proof attestation tool generates SNARK cryptographic proofs of queries within its decentralized data network, ensuring the accuracy and integrity of data queries. SQL proofs enable decentralized applications (DApps) to run queries against Space and Time’s data warehouse, aggregating results into smart contracts. The technology aims to provide tamper-proof on-chain and off-chain data for various applications, including blockchain services, advanced computing, artificial intelligence, and large language models.
The development of ZK-proof and Blitsar is supported by partnerships with hardware manufacturers, particularly leveraging NVIDIA GPUs. Blitsar can potentially benefit Ethereum layer 2 protocols such as Polygon zkEVM and zkSync Era by optimizing their ZK proof generation. While the ZK proof protocol gains traction in 2023, Space and Time's focus on GPU acceleration aims to contribute to the broader optimization and efficiency of cryptographic processes in the Web3 ecosystem.
