Project Description

The Datum network will be a decentralized databank and marketplace in which individuals can store and sell their data. The Datum network aims to help internet users regain control over their data.

It allows individuals to to backup their personal data, such as social network data and data from wearables and other IOT devices, on the Bigchain DB blockchain. User data is submitted via the Datum client to the network and encrypted with the usage rules set by the data owner.

Datum plans to use the IPFS distributed data storage protocol. On the network data is replicated to storage nodes, part of the Bigchain DB cluster. Miners provide computing power and storage capacity in return for DAT tokens.

Eventually, users will be able to sell data on the Datum marketplace. Ethereum smart contracts initiate the release of sold data in accordance with the usage rules set by the data owner. The exchange of data is paid in DAT tokens.

Datum network consumers consist of trusted non-profit entities, such as researchers and NGOs, as well as private companies. Consumers benefit from direct access to validated and verifiable data. Once data consumers show interest in purchasing data, the user receives a detailed purchase request. The user can agree to the request and send the decryption key to the data consumer or counteroffer with a modified proposal. The Datum network emphasizes the credibility of the data consumer as an important aspect in this procedure and believes this will incentivize data consumers to build a trusted track record.
