Explanation
This PR adds a new
eth_getPlumeSignature
RPC method that implements a novel ECDSA nullifier scheme as described in EIP-7524.The
eth_getPlumeSignature
method takes in two parameters, a message and an address, then generates a deterministic signature (PLUME) and several other inputs. The plume can be used as a nullifier to prevent double-spending in an anonymity set. This capability unlocks novel on-chain behavior, such as private DAO voting, fair, non-doxxing airdrops, and more.Screenshot
