Data have become one of the most valuable commodities of our time, with the size of data markets expected to reach EUR 100 billion by 2025.

The EU-funded SEDIMARK project aims to create a secure decentralised data marketplace based on distributed ledger technology and AI. Under this new system, the data will no longer be stored on the cloud but on edge systems, close to where they are generated, thus avoiding many security issues. They will then be cleaned, labelled and classified, through energy efficient techniques, making for a more secure environment where findable, accessible, interoperable and reusable (FAIR) and high-quality data can be easily linked, shared and utilised.

  • SEDIMARK merges the expertise of a large team of experts to build a secure, trusted and intelligent decentralised data and services marketplace, based on Distributed Ledger Technology and Artificial Intelligence.
  • SEDIMARK enables distributed heterogeneous data within the EU to be easily and seamlessly linked, shared and exploited for diverse business and research scenarios.
  • SEDIMARK builds upon the concept of FAIR data, ensuring that data are of the highest quality, unbiased, enriched and annotated, so that they can be discovered, accessed, and easily reused.
  • SEDIMARK includes a distributed registry of resources (data/services) stored on edge systems, close to where they are generated and where the data are cleaned, labelled, validated and anonymised. Security is applied with strong access control, privacy techniques for data minimisation and purpose limitation, exploiting blockchain for enforcing trust, decentralised identities, and data verification.
