Systems and methods which provide data exchange using a distributed ledger, wherein data is exchanged off-chain and information for accessing the off-chain data is exchanged through the blockchain, are disclosed. Embodiments may provide a hybrid blockchain data exchange platform storing large amounts of data (e.g., IoT data) in a data server outside of the blockchain, wherein a data consumer may obtain data from the data server using a token obtained from the blockchain. Embodiments of a hybrid blockchain data exchange platform provide for accuracy and security of the data without requiring storage of the full contents of the data within the blockchain, and/or provide data exchange in which the irrefutability of the data exchanged is ensured.
