A signature suite based on signing strings prefixed in Ethereum Personal Message (
personal_sign
) format.Like Ethereum EIP712 Signature 2021 and Eip712Method2021, but for when you have
personal_sign
but noteth_signTypedData
. Uses URDNA2015 and N-Quads (like TezosSignature2021).The string for signing is the canonicalized N-Quads of the proof options, followed by a newline, followed by canonicalized N-Quads of the linked data proof (e.g. verifiable credential). This string is prefixed and hashed according to "Ethereum Personal Message" signing.
