Depending on data sensitivity, costs and the data protection guidelines of each participating company, it might be preferred to store sensitive data at each participants site on-premise in off-chained storage facilities, e.g. databases or DMSs or on-premise private blockchain nodes in case of later stage hybrid solutions. The data that is transferred using the system is not based on a coin of any kind. In case of future hybrid solutions, i.e. storing the hash value in the public blockchain and meta data and / or the documents themselves in a secured private blockchain, moving to the private blockchain could be accomplished using data-based tokens. As the system matures, it is possible to create a cryptocurrency, which can be used to settle payments stemming from the contractual agreements, stable coins pegged to fiat currencies like Euro or Dollar could also be realised on a coin-based blockchain.
