Constantine-backed protocols

This folder stores protocol implemented on top of Constantine.

Ethereum Virtual Machine

Constantine implements precompiles primitives for the Ethereum virtual machine

  • ECADD on BN254_Snarks (called alt_bn128 in Ethereum), address 0x6, spec EIP-196 and pricing EIP-1108
  • ECMUL on BN254_Snarks (called alt_bn128 in Ethereum), address 0x7, spec EIP-196 and pricing EIP-1108
  • ECPAIRING on BN254_Snarks (called alt_bn128 in Ethereum), address 0x8, spec EIP-197 and pricing EIP-1108

Their main use-case is for use zero-knowledge proofs and zkRollups and be compatible with work on Zcash
