Expand description
A vector of UpdateProofs are sent as the proof to a history query for a particular key. For each version of the value associated with the key, the verifier must check that:
- the version was included in the claimed epoch,
- the previous version was retired at this epoch,
- the version did not exist prior to this epoch,
- the next few versions (up until the next marker), did not exist at this epoch,
- the future marker versions did not exist at this epoch.
Fields
epoch: u64
Epoch of this update
plaintext_value: AkdValue
Value at this update
version: u64
Version at this update
existence_vrf_proof: Vec<u8>
VRF proof for the label for the current version
existence_at_ep: MembershipProof
Membership proof to show that the key was included in this epoch
previous_version_vrf_proof: Option<Vec<u8>>
VRF proof for the label for the previous version which became stale
previous_version_stale_at_ep: Option<MembershipProof>
Proof that previous value was set to old at this epoch
commitment_proof: Vec<u8>
Proof for commitment value derived from raw AkdLabel and AkdValue
