Expand description

Proof that a given label was at a particular state at the given epoch. This means we need to show that the state and version we are claiming for this node must have been:

committed in the tree,
not too far ahead of the most recent marker version,
not stale when served. This proof is sent in response to a lookup query for a particular key.

Fields

epoch: u64

The epoch of this record

plaintext_value: AkdValue

The plaintext value in question

version: u64

The version of the record

existence_vrf_proof: Vec<u8>

VRF proof for the label corresponding to this version

existence_proof: MembershipProof<H>

Record existence proof

marker_vrf_proof: Vec<u8>

VRF proof for the marker preceding (less than or equal to) this version

marker_proof: MembershipProof<H>

Existence at specific marker

freshness_vrf_proof: Vec<u8>

VRF proof for the label corresponding to this version being stale

freshness_proof: NonMembershipProof<H>

Freshness proof (non membership of stale label)

commitment_proof: Vec<u8>

Proof for commitment value derived from raw AkdLabel and AkdValue
