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.
