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.
