US11863680B2	Linking blockchain records to identify certification, track pedigree and identify obsolete digital content A permissioned blockchain, using off-chain storage, provides advantages over blockchains that rely on consensus and/or store information within the blockchain. Advantages include enhanced viability, compactness, and the ability to register material with distribution limitations (e.g., military classified). Examples create an immutable public record of data signatures that confirm when data is intact, without distributing the data itself, so that widespread availability of the blockchain (beyond those privileged to see the data) advantageously increases the size of the community that is able to detect spoofing or forgery attempts. A permissioning entity limits submissions to manage blockchain growth, foreclosing problematic material that may risk long-term viability. Examples render blockchain operations resistant to advanced persistent threats (APTs), leverage digital signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.
