Abstract: A blockchain token may be transferred from a current owner of the blockchain token to a different user responsive to an instruction to transfer the blockchain owner from the current owner to the other user, with or without the blockchain owner's knowledge or involvement. This may comprise a smart contract that minted the blockchain token and/or that permits transferee-initiated transfer of the blockchain token. The smart contract may further condition transferee-initiated transfer on a maximum number of blockchain tokens associated with a digital file that are permitted to be transferred to a single blockchain wallet, a maximum number of transferee-initiated transfers of a blockchain token, a maximum amount of transfer fees for transferring one or more blockchain tokens associated with a digital file, and/or a successful match of a code to a stored code.

Abstract: Systems and methods for encryption using blockchain distributed ledgers include a memory, one or more processors in communication with the memory, and program instructions executable, via the memory, by the one or more processors to, in part, encrypt, via a symmetric key, multiple documents to be incorporated into a single non-fungible token (NFT). Further, a data file including a portfolio array of links to each encrypted document of the multiple encrypted documents is generated, and a mint function is executed to create the single NFT on a blockchain, where the single NFT includes a link to the generated data file. The single NFT is transmitted to a digital wallet of the blockchain.

Abstract: Systems and methods for secure data replication and original destruction using a blockchain distributed ledger include program instructions to generate an NFT on a secondary blockchain platform in response to receiving a request to transfer an existing NFT from an original blockchain platform to the secondary blockchain platform, the generating including accessing a smart contract deployed on the secondary blockchain platform and is configured to execute a mint function. The program instructions execute the mint function of the smart contract, the executing including copying existing NFT data of the existing NFT from the original blockchain platform to the generated NFT, and store on the secondary blockchain: (i) a pointer to identify the existing NFT of the original blockchain platform and a transaction hash associated with a most recent transaction involving the existing NFT. The program instructions transmit the generated NFT to a digital wallet of the secondary blockchain platform.
