Top 4 snark open source projects

groth16
A Rust implementation of the Groth16 zkSNARK
verifiable mpc
A scheme that produces a zero-knowledge proof of correctness for an MPC computation. The scheme allows anyone, particularly someone external to the secure computation, to check the correctness of the output, while preserving the privacy properties of the MPC protocol.
Groth16BatchVerifier
Batch verification proposal for the zkSNARK verification with the same(!) circuit
crypto-primitives
Interfaces and implementations of cryptographic primitives, along with R1CS constraints for them
