Use cases may need to use blockchain technology to add traceability to certain business operations and assets. When using data outputs in transactions, the Hathor network creates a token representing an operation/asset, and the related metadata is recorded either on IPFS (in this case the blockchain stores the link to it) or directly on the blockchain (e.g. a data hash). This token is unitary as it solely works for grouping transactions. Hence, all transactions for the token can be browsed and the whole information history accessed. As with an NFT transaction creation, the data key is added to an output by spending 0.01 HTR.
