€ 1.6 million open call for web 3.0 innovators to develop blockchain-related solutions

The EU-funded project ONTOCHAIN is calling all Web 3.0 innovators to apply for its third open call and co-develop a new software ecosystem for trusted, traceable, and transparent ontological knowledge management. 
ONTOCHAIN offers a 10-month supporting programme with grants up to € 119.500 (equity-free), coaching, access to top infrastructure (iExec and MyIntelliPatent), visibility and joint exploitation opportunities. A total budget of € 1.673.000 is available to empower the best projects.
The ONTOCHAIN Open Call 3 will support the development of interoperable and sustainable applications that employ both Semantic Web and Blockchain concepts to enhance data quality aspects (E.g. high-level semantics, completeness, data uniqueness, timeliness, validity, integrity, privacy, consistency, assets trading and monetization, tokenomics principles, the use of application-level proofs and decentralised digital identities) and the trustworthiness of data communication and handling processes. Applications should be able to build on top of software services of the ONTOCHAIN ecosystem, and should cover real needs of end users from various vertical domains/vital sectors of the European economy.
