This is an implementation for a decentralized trustless bridge paper. This is a prototype, not a full implementation of the Sisu protocol. You are welcomed to modify and use the code but it's not ready for production.
You will need a NVIDIA graphic card and nvidia-smi command tools installed to run.
The src/main.rs contains various tests for public key aggregation, Merkle tree proof, VPD, etc. The groth16 folder contains code for distributed MSM computation in groth16. sha256-circuit and pubkey-aggregation are optimized circuit for public key SHA256 & pubkey aggregation in Ethereum consensus. bls-circom consists of verification program written in Circom language to verify the Phase 1 of Sisu.
We test on a machine Intel(R) 8 cores i7-7700 @3.60GHz CPU, 32GB RAM and Geforce GTX 1080 (8GB VRAM) GPU. This is a modest hardware configuration. One Geforce GTX 1080 can generate proof for 16 validators. Fully optimized code can handle 32-64 validators as many of the code is not moved to GPU yet.
