The Project

Interoperable decentralized identity pilot project  

Start4big, the first European multi-sector open innovation initiative promoted by Aigües de Barcelona, CaixaBank, Naturgy, SEAT, and Telefónica. 192 proposals were submitted, and Validated ID was among the 6 winners.

CaixaBank issues an account ownership credential used to proceed with the direct debit of the invoices of Aigües de Barcelona. Aigües de Barcelona gives a payment approval credential to obtain a better score when requesting a loan from CaixaBank. These are the two use cases tested during the pilot project.

The pilot phase has helped build an identity solution that enables the identification of a customer and the exchange of secure information between two companies. Interoperability between blockchain networks and sovereign digital identity standards has been successfully tested.

Benefits:

  • It helps companies and users take control of their digital identity  
  • Optimizes the direct debit of bills in Aigües de Barcelona  
  • Improves the risk scoring of a potential new CaixaBank customer  
  • Facilitate secure user access to online services
