Opening date: January 27, 2022 – 12:00 PM CET

Closing date: March 30, 2022 – 17:00 PM CET 

Apply here and now: TruBlo Open Call #3

Describe your early stage idea for  “trusted content on future blockchains”. On this page you will find all needed information, documents for participation, including a link to the F6S platform where applications will be managed. 


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).


Phase 1: Innovation (9 months)

Up to 20 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

  • 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

Phase 2: Progress (6 months)


A subset of  four  projects from Phase 1  from Open Call #3 will be selected to further develop activities associated with the demonstration/ piloting as well as promotion and exploitation of their project, building an MVP as demonstrator and aiming to engage new customers and/or partners and/or investors.

  • 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
  • MVP in form of a prototype / demonstrator
  • Demonstration of developed solution with users / customers
  • Collection of insights and assessment report 
  • Business Model Canvas 
  • White paper detailing the technical aspects of the MVP along with an analysis of future potential and impact
  • Scientific publications and jointly authored publications with other teams (optional result).

These expected results must be concreted in the below deliverables:

  • D2.1 Detailed Development Plan
  • D2.2 Detailed Development Plan Monitoring 
  • D2.3 Validation Plan
  • D2.4 Final report of MVP
  • D2.5 Demonstration of developed solution with users
  • D2.6 White paper

D2.7 Business Plan


6 months

  • Total funding of up to €100,000 (in addition to the funding from the innovation phase). 

Distributed over two sprints of three months each and according to the achievement of specific defined milestones/ objectives and participation in TruBlo events/ bootcamps (Validation & Pitch: 30%, Delivery plan in sprint 1: 20%; Mentor Meeting in Sprint 2: 50%)

Support from the consortium

TruBlo provides a unique and competitive mixture of support services for the funded parties. The offering includes technical support services, Business and Innovation Support  as well as Technical Knowledge Support.


Technical Support Service (TESS)

Alastria is part of a non-profit association promoting the Digital Economy through the development of decentralized technologies/blockchain. 

Alastria will provide blockchain infrastructure to the funded companies – helping to test and scale innovations quickly, with support from an experienced organisation.

 The Alastria network is currently able to manage transactions at a high frequency, obtaining blockx with mor than 1000 tx and a throughput of ca. 1000tx/s. 

Business and Innovation Support Services (BISS)

These services will be provided to funded companies to facilitate and enhance innovation. The focus is on further developing innovative prototypes and applications for distributed trust. How can the business applicability be enhanced? Included in this offer is feedback on the innovation and fine-tuning and business modelling. Another element is the a “Talk to users” Hotline, meaning that funded companies can pitch their ideas to potential users and receive deeper insights this way. 

Technical Knowledge Support & Training (TEKSUS)

A package of services to answer technical questions, provide scientific content and advice on demand. To this end TruBlo will create a Learning Management System (LMS), for use by the funded teams.The platform will incldude a library, forum and chat for digital exchange. 

The offering includes mentoring to solve technical challenges, background and baseline knowledge to support the innovations. 

Another element is technical coordination, to ensure that the thematic and technical coordination of the projects is optimised.
