Blitzar is a C++ library (with Rust bindings) that accelerates zero-knowledge proof algorithms on CPU and GPU using CUDA. It was built by Space and Time to speed up Proof of SQL and is open-sourced for the Web3 community to build GPU-accelerated ZK proofs.
Use cases
- accelerate zero-knowledge proof generation with GPUs
- speed up cryptographic commitment computation over millions of rows
- build GPU-accelerated ZK proof systems in C++ or Rust
- prove SQL queries over large datasets in under a second
- compute curve25519 elliptic curve operations fast
When to choose
- you need GPU acceleration for ZK proof generation at scale
- you are building zero-knowledge proofs in C++ or Rust on Linux with NVIDIA GPUs
- you need fast multi-scalar multiplication or curve operations
When to avoid
- you need a full ZK proof system or verifier rather than acceleration primitives
- you are not on Linux x86 with CUDA-capable NVIDIA GPUs
- you need a high-level proof DSL rather than a low-level crypto library
