Teaser of the company

Euroledger is building a user activation tool for marketplaces, enhancing trust between their users by facilitating transfer of their reputational data from other platforms in a verified way.

Euroledger has developed the following blockchain-based prototype in the scope of BlockStart:

Capena – SaaS for marketplaces that allows their users to make their reputational data visible across platforms in a verified way


The user credentials, related to the users’ accounts on platforms B, C and D, are stored in the user’s wallet with identifiers and schemes sitting in the Verifiable Data Registry.  The credentials are transferred from the wallet to platform A on demand and upon permission from the user. Platform A verifies identifiers and schemas with the Registry. Digital Identity is using a custom build blockchain system – Aries technology (built on Hyperledger Indy).

The solution is pluggable to any software architecture – the plugin is a generic, light-touch component. From the regulatory perspective, the solution is GDPR compliant and adheres to the W3C standard (Verifiable Credentials Data Model).

Technical development during Prototype stage

The prototype was fully built and tested in a controlled environment during BlockStart.

Business development during Prototype stage

During BlockStart, the commercial product was developed, and the size of the market was estimated.  Four-year detailed financial model was built.  Business development was started and resulted in acquiring 5 prospective adopters from an initial pool of 65 potential customers.

Euroledger’s journey with Blockstart was about building a prototype and a business model. Blockstart added value by checking for inconsistencies, typos and other irregularities in the reports and presentations, providing feedback of general nature and advising on specific Horizon 2020 rules and procedures.
