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signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.

In certain embodiments, transaction data retrieval from a postage vendor system database may be facilitated (e.g., via label generation with multiple barcode representations of a portion of a postage tracking identifier, where the tracking identifier is generated based on a carrier-specific tracking identifier unique within a carrier system with respect to accounts recognized by the carrier system). In some embodiments, the tracking identifier may be generated such that (i) the tracking identifier comprises the carrier-specific tracking identifier and (ii) enables a mail piece associated with a postage transaction to be tracked within the carrier system, and the tracking identifier portion is allocated to the postage transaction in one or more databases of the vendor system. An indicium identifier may be generated to comprise the tracking identifier portion, thereby enabling the vendor system to identify the postage transaction using one of the two identifiers without the other one of the identifiers.
