Insights Network is a blockchain based data broker constructed to empowers the data subjects as data providers. The solution challenges existing data brokers by allowing the individual data subjects to control and to capitalize on their own data. The combined use of blockchain and MPC ensure that the bilateral exchange of data happens frictionless and without involving anyone but the data requester and the data providers. Also, the exchange of data and payment is controlled by neither the requester nor the provider and is enforceable without any third party involvement.
A unique infrastructure with no single point of trust provides transparency by use of Blockchain and privacy by use of Secure Multiparty Computation (MPC). Partisia developed the basic infrastructure and designed new MPC protocols that meet the requirements for the decentralized peer-2-peer infrastructure. The first complete version of the unique infrastructure behind the blockchain based data broker – Insights Network – was deployed in 2018.
