Datum is the decentralized marketplace for social and IoT data. The Datum network allows anyone to store structured data securely in a decentralized way on a smart contract blockchain. The DAT smart token enables optional selling and buying of stored data while enforcing data usage rules as set by the data owner.

Key Elements

• A fast decentralized data store allowing users to store structured data securely running on a smart contract blockchain
• The DAT token enabling this data storage and sharing
• The data marketplace, enabling individuals to monetize their data on their terms
• Datum leverages BigchainDB and IPFS to provide an infinitely scalable, decentralized data storage backend
• Data storage and data sharing is paid for by the DAT token

Data Network Incentives

• Users:
  1. Control of use of data
  2. Secure and infinitely scalable data storage
  3. Monetization of data
• Data​ ​Consumers:
  1. Direct access to validated and verifiable data
  2. Lower costs by eliminating “data broker” middlemen
• Storage​ ​Node:
  1. Rewards for hosting data and providing compute power

Use Cases

1. User submits a piece of data to the Datum Network using the client software. The user pays gas to submit the data. As the data is encrypted, only the user can provide a decryption key to all the interested parties.
2. A Storage node receives the data and stores the data. The data is replicated to many other storage nodes.
3. A Data Consumer declares interest to purchase the piece of data.
4. The user receives a data purchase request with the details such as purchaser and price offered. He can agree to purchase request or counter offer with a modified proposal.
5. The User accepts the proposal, the user receives DAT Tokens and the decryption key is sent to the Data Consumer who pays in DAT Tokens.
