Aegis

This is the proof of concept presented in our paper "Aegis: Privacy Preserving Market for Non-Fungible Tokens".

Getting started

• Install Node.js
• Install Circom 2
• Run npm i to install dependancies
• Run npm run build:circuits to build the zkSNARK artifacts
• Run npx hardhat test to test a full scenario of for list of commands

Notes

• To change the Merkle tree depth:
  • Update TREE_DEPTH in contracts\Commitments.sol
  • Update the last parameter in circuits\*.circom
  • Update TREE_DEPTH in test\aegis.test.js
  • Run npm run build to rebuild the artifacts
• To measure the circuit R1CS constraints:
  • Make sure you have built the artifacts by running npm run builds
  • cd /build
  • Run npx snarkjs r1cs info #x where #x is the *.r1cs file (e.g. JoinSplit.r1cs)
