AnonCreds Revocation List Model

Currently the revocation state is calculated each time in Indy Credx / Indy SDK by starting from sratch, and adding all revoked/issues indices to it to calculate the witness

{
    "revocation_list": [0,1,0,1],
    "current_accumulator": "xxx",
    "timestamp": "xxx"
}

• revocation_list (number[]) - bit array indicating the . Number of bits in the array is equal to the maxRevocationSize as configured in the revocation registry (1=revoked, 0=non-revoked/issued)
• current_accumulator (number) - The current accumulator value

Questions

• Do we need to think about impact of verifier needing to retrieve the whole revocation list? The verifier doesn't need to know the full state of the revocation list, it just needs to know the accumulator.

Notes

• Methods can choose to use compression to store the list (e.g. GZIP as used by StatusList2021)
