It addresses the growing demand for a single European Data Market Economy by enabling secure and privacy preserving data sharing across data spaces and marketplaces. Above all, it aims at providing technologies for trustworthy (secure and reliable), data-driven collaboration and federation of existing and new future marketplace platforms. 

Special attention is given to industrial data, particularly sensitive commercial data assets from both SMEs and large industrial corporations.

It is well known that despite various research and innovation attempts working on Big Data management and sharing, there is no broadly accepted trusted and secure solution for federation of data marketplaces. 

i3-MARKET is addressing this gap by developing lacking technologies and solutions for a trusted (secure, self-governing, consensus-based and auditable), interoperable (semantic-driven) and decentralised (scalable) infrastructure.

The i3-MARKET Backplane enables federation via interoperability of the existing and future emerging data spaces and marketplaces.

i3-MARKET Backplane

It innovates industry solutions by developing the lack of building blocks to overcome the barriers on interoperable and integrative data marketplaces. Architecturally speaking, i3-MARKET uses trusted, federated and decentralised software components, enabling the integration of other marketplaces. The architecture is designed to enable secure and privacy preserving data sharing across data spaces and marketplaces, through the deployment of a backplane across operational data marketplaces.

Industrial Pilots

The consortium has implement and integrated the i3-MARKET backplane in three industrial domains (Industrial pilots), which examine the viability of the implementation, test its reliability and validate whether it’s scalable in real industrial environments.
