A JavaScript and pure WebAssembly implementation of zkSNARK schemes including Groth16, PLONK, and FFLONK. It provides all tooling for generating and verifying zero-knowledge proofs and running multi-party trusted setup ceremonies, working in Node.js and the browser.

Use cases

• generate and verify zkSNARK proofs from circom circuits
• run a multi-party trusted setup ceremony for a zk circuit
• prove statements in zero knowledge for an Ethereum dapp
• verify zero-knowledge proofs in the browser
• participate in a powers of tau ceremony
• compile and prove circuits with Groth16 or PLONK

When to choose

• you need a pure JavaScript/WASM zkSNARK toolkit without native dependencies
• you are building zero-knowledge applications on Ethereum or other chains
• you need to orchestrate phase 1 or phase 2 trusted setup ceremonies
• you want proofs generated in Node.js or directly in the browser

When to avoid

• you need maximum proving performance from native GPU or Rust implementations
• your project requires a permissive license (snarkjs is GPL-3.0)
• you need zk-STARKs or schemes outside Groth16/PLONK/FFLONK
• you are not working with circom-compiled circuits
