Patent attributes
Techniques for facilitating secure and scalable data transfers using a hybrid blockchain-based approach are provided. In one embodiment, a first computer system at a first site can transmit a token to a second computer system at a second site, where the token includes metadata regarding a data set to be transferred from the first computer system to the second computer system and one or more cloud storage service addresses where the data set will be temporarily stored. The token can be transmitted using a blockchain network that is accessible to the first and second computer systems via a public network. The first computer system can then upload the data set to the one or more cloud storage service addresses via the public network, and the second computer system can download the data set from the one or more cloud storage service addresses via the public network.
