Abstract
Blockchain-based file handling is provided by receiving a data file from a user device, storing the data file to local storage of the blockchain peer, generating a file identifier of the data file, providing the file identifier to the user device, storing the file identifier to a synchronized ledger of the blockchain network, where the synchronized ledger tracks access to the data file, and distributing data of the data file to one or more other blockchain peers of the blockchain network.
Claims15
A computer-implemented method comprising:
- receiving, by a blockchain peer of a blockchain network, a data file from a user device;
- storing, by the blockchain peer, the data file to local storage of the blockchain peer;
- generating a file identifier of the data file;
- providing the file identifier to the user device;
- storing the file identifier to a synchronized ledger of the blockchain network, the synchronized ledger tracking access to the data file;
- and
- distributing data of the data file to one or more other blockchain peers of a plurality of blockchain peers of the blockchain network, wherein the distributing comprises splitting the data of the data file into a plurality of separate data files and distributing a respective at least one separate data file of the plurality of separate data files to each of the one or more other blockchain peers, wherein the distributing distributes to at least one of the one or more blockchain peers some, but not all, separate data files of the plurality of separate data files, and wherein the distributing further comprises at least one selected from the group consisting of:
- compressing data of the data file, or the plurality of separate data files, to obtain compressed data, and distributing the compressed data to the one or more other blockchain peers;
- and
- encrypting data of the data file, or the plurality of separate data files, to obtain encrypted data, and distributing the encrypted data to the one or more other blockchain peers.

A computer program product comprising:
- a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
- receiving, by a blockchain peer of a blockchain network, a data file from a user device;
- storing, by the blockchain peer, the data file to local storage of the blockchain peer;
- generating a file identifier of the data file;
- providing the file identifier to the user device;
- storing the file identifier to a synchronized ledger of the blockchain network, the synchronized ledger tracking access to the data file;
- and
- distributing data of the data file to one or more other blockchain peers of a plurality of blockchain peers of the blockchain network, wherein the distributing comprises splitting the data of the data file into a plurality of separate data files and distributing a respective at least one separate data file of the plurality of separate data files to each of the one or more other blockchain peers, wherein the distributing distributes to at least one of the one or more blockchain peers some, but not all, separate data files of the plurality of separate data files, and wherein the distributing further comprises at least one selected from the group consisting of:
- compressing data of the data file, or the plurality of separate data files, to obtain compressed data, and distributing the compressed data to the one or more other blockchain peers;
- and
- encrypting data of the data file, or the plurality of separate data files, to obtain encrypted data, and distributing the encrypted data to the one or more other blockchain peers.
