TrustChain project started in January 2023 to address the inherent challenges within the current centralised Internet architecture that is not transparent to the user, does not protect the privacy-by -default and does not scale well through 5 Open Calls and an overall budget of €8,775M.
The TrustChain Open Call 4 topic is “Multi chains support for NGI protocols”.
Until July 17th (17:00 CEST) TrustChain Open Call 4 welcomes applications to design and build the gateways that will make it possible to transfer knowledge/ metadata/ data/ process/ requirements from one chain to another in a trustworthy and secure manner. Interoperability across multiple chains, privacy by design, trustworthiness by design, scalability, greenness, openness, and legal compliance should be carefully considered.
