Abstract
This document describes the TODA Protocol’s Proof Of Provenance (POP) data structure. In particular, it provides the data layouts for version one of the POP parts, which are used when hashing those parts for inclusion as well as at rest and on the wire. It serves as the canonical source and normative specification for all V1 POP structures.
In addition to the concrete data structure descriptions, this document also includes brief descriptions of the algorithms for constructing certain portions of that data structure, an abstract description of and motivation for particular pieces, and proofs of the integrity guarantees provided by the POP structure.
