A method includes receiving, from a source user account associated with a source digital wallet of a source blockchain, a request to perform a cross-chain operation from the source blockchain to a destination blockchain. The source blockchain is associated with a source token contract that stores a delta value indicative of a difference between a total number of tokens having an attribution property in circulation of the source blockchain and a number of tokens having the attribution property in circulation of the source blockchain that are accounted for by a vault of a primary blockchain. The attribution property identifies a token issuer. The method further includes causing a cross-chain message including a transaction payload to be generated based at least in part on the delta value, and causing the transaction payload to be applied to the destination blockchain.

Systems and methods that facilitate data access by multiple unconnected entities, each having access to a data storage system storing data relating to a specific topic. A computer-readable data file containing access details for the data is generated and stored elsewhere in the data storage system. A non-fungible token (NFT) is generated that is uniquely assigned to the topic of the data, and is recorded on a blockchain ledger. The NFT has a metadata file that is uniquely associated to that NFT and that contains a pointer to the computer-readable data file containing the access details. Thus, with access to the NFT, an entity can open the metadata file, follow the pointer to the computer-readable data file, use the computer-readable data file to obtain the access details, and access the data itself using those access details. In some embodiments, the access details and/or the data are encrypted.

A service accesses an electronic file, which is associated with metadata. As a part of a repository transaction, the metadata is stored in a repository. The service triggers generation of an authentication hash on the electronic file and also triggers generation of a transaction hash on at least the repository transaction. The service then causes both the authentication hash and the transaction hash to be stored in a blockchain while refraining from causing the electronic file and the repository transaction from being stored in the blockchain.
