On this page you will find all needed information, documents for participation, including a link to the F6S platform where applications will be managed. 

The call will be open for researchers, innovators, developers from academia, startups, high tech companies or natural persons.  

Focus of the call

Trust is essential to societies. But currently an increasing amount of disinformation makes it difficult to trust information in our multiple daily interactions.

  • How could we use scalable blockchain technology for new protocols, apps, solutions or platforms?
  • How could we combine blockchain and content to ensure trustworthy and reliable content?

The objective of the TruBlo Open Call No. 3 is to invite academic teams, researchers, SMEs and startups to define and implement small scale research projects on one of the two topics:

  • Trust and reputation models on blockchains

This focus area targets innovative applications, technologies, technical approaches and methodologies that increase the level of trust in blockchain-based information exchange, with emphasis on user generated content on the internet and social media, considering also data from IoT (Internet of things) infrastructures.

  • Proof-of-validity and proof-of-location 

This focus area aims to find innovative mechanisms to increase transparency and trustworthiness of user generated genuine content. For example: How could users, being part of a blockchain, add or apply additional verification mechanisms to increase transparency, validity and high level of trustworthiness, such as Proof-of-Location and Proof-of Validity? Such applications will be disseminated through the European Digital Media Observatory (EDMO).

TRUBLO Open Call No. 3
is broken into two phases:

Phase 1: Innovation (9 months)

Up to 15 projects will be selected in the innovation phase to develop their proposed project and prepare a publication (whitepaper or scientific article) describing their solution.

  • R&D activities from concept to validation
  • Participation in TruBlo kick-off bootcamp, webinars, etc. 
  • Presentation/sharing results to community 
  • Open software/ hardware
  • At least one scientific publication
Expected results and Deliverables
  • Validation of a research concept in a specific environment (preferably in Alastria infrastructure and/or EDMO infrastructure but not obligatory for the participating teams)
  • White paper / Technical report with the description of the research result and analysis on the impact it can have in the industry
  • Publication of additional papers in other conferences, magazines and (scientific) journals (optional result)
  • Joint publication with other teams (optional result)

These expected results must be concreted in the below deliverables:

  • D1.1 Full Research and Innovation Project Proposal
  • D1.2 Project Solution Design and Business Applicability
  • D1.3 White paper or Technical report  or PoC

  • Build synergies and have cross-collaboration activities with other projects and/or stakeholders
  • Create a Proof of Concept and Minimum Viable Product (MVP) 
  • Validation of MVP in a specific environment (preferably in Alastria infrastructure and/or EDMO infrastructure but not obligatory for the participating teams)
  • Work together with potential users / customers (early adopters) 
  • Participate in knowledge transfer events organised by TruBlo Consortium
Expected results and Deliverables
