Abstract: Computer methods and systems provide management of payload data represented by electronic tokens. Applications may relate to asset-backed fungible tokens as well as non-fungible tokens. A payload data file may be added or kept current after initial token genesis by specifying, in token data, a pointer (e.g., as either a TXID specifying a wallet address as an endpoint, or as the wallet address) to one or more transactions that carry, such as in an OP_Return field, a link to a linking payload or to the added or current payload data file. A single transaction specifying the wallet address may thus update or add incremental data to any number of electronic tokens linked to the payload data file.

Abstract: A computer method, graphical user interface, non-transitory computer readable medium, and system provides a facility for storing data to inherently maintain immutable proof of content as originally stored, including encrypted content. User-specific access to payload data may be provided according to selected credential privilege carried by metadata instances. One or more blockchain transactions carry data for accessing stored data instances on a distributed file system (DFS), such as IPFS or FileCoin, or web address.
