Unlocking the value in data
Open Data Markets Infrastructure
XBR creates the infrastructure for running decentralized data markets. These data markets can be created as needed and to fulfill the entire variety of participants' requirements. They enable API-based, secure and real-time data sharing between particpants. The XBR token is the means of payment within all XBR data markets.
Technology
XBR Data Markets and the Ethereum Blockchain
Data is traded within XBR data markets. These run under the control of individual market providers. They can be set up to fit any specific needs.
Particpants can be members in multiple markets.
Participants and data markets register with the XBR smart contracts on the Ethereum blockchain.
Payment within markets utilizes the XBR token. Tokens are locked into a market, and invidual transactions are handled in the market. Token balances are periodically cleared on the Ethereum blockchain.
Encrypted Data Exchange Based on Crossbar.io
Data providers and data consumers each establish a single connection to the Crossbar.io-based infrastructure of a XBR data market.
Data providers publish data update streams, and these are automatically delivered to all subscribed data consumers.
Data consumers request specific information by making API calls, with the call routed via Crossbar.io.
Data updates and call results are encrypted by the data provider.
Key Exchange in the XBR Data Market
The data provider shares an encryption key for data transmitted via the data provider's API.
This can be e.g. for a particular API call or for a set of past and future events.
The data consumer provides the agreed amount of XBR tokens as payment for the encryption key.
The market maker code handles the exchange of encryption key and XBR tokens.
