Expand description

This proof is an array of UpdateProofs and proofs of non-membership of future entries

Fields

update_proofs: Vec<UpdateProof<H>>

For each version v = 1…n of a user’s key, include a proof that the previous version was retired at the same time as this version was added. (for version 1, it’s just a mem proof).

next_few_vrf_proofs: Vec<Vec<u8>>

VRF Proofs for the labels of the next few values, these are values in the set [latest_version + 1, …, 2^(log(latest_version+1))-1]

non_existence_of_next_few: Vec<NonMembershipProof<H>>

Proof that the next few values did not exist at this time

future_marker_vrf_proofs: Vec<Vec<u8>>

VRF proofs for the labels of future marker entries, these are values with version numbers [2^(log(latest_version+1)), …, 2^(log(latest_epoch))]

non_existence_of_future_markers: Vec<NonMembershipProof<H>>

Proof that future markers did not exist
