Trust One (blockchain)

2021: Start using the service for storing covid passports, at 12 airports in Spain

In early May 2021, TE-FOOD announced that its Trust One blockchain solution for covid passports began to be used at 12 Spanish airports to store health certificates after conducting tests for COVID-19 coronavirus. The technology after testing began to use:

• La Palma Airport;
• Barcelona International Airport;
• Alicante International Airport;
• Lanzarote Airport;
• Palma de Mallorca International Airport;
• Ibiza Airport;
• Fuerteventura International Airport;
• Menorca Airport;
• Tenerife International Airport;
• Bilbao International Airport;
• Valencia Airport;
• Gran Canaria Airport.

The system operates as follows:

• a person passed a PCR test in the laboratory or was vaccinated;
• he adds the corresponding certificate to the Trust One blockchain system;
• the user arrives at the airport, where the employee scans the QR code from the smartphone;
• this QR code shows the result of a PCR test or grafting.

Experts note that paper certificates with analysis results or vaccination data can be easily copied and forged. Spain It has already introduced a system of digital certificates of vaccination (covid passports), which allow foreign tourists to enter the country, and many companies began to offer a number of blockchain-based solutions aimed at checking issued certificates.

12 Spanish airports began to accept covid passports stored in the blockchain Trust One

TE-FOOD entered into a partnership agreement with Eurofins Megalab, which installed COVID analysis stations at 12 Spanish airports. The results of the analyses will be recorded in the Trust One blockchain system, which allows you to quickly verify the reliability of the data provided.

By early May 2021, the Trust One blockchain system is not used to check health passports upon arrival of passengers at Spanish airports - it is used only to issue a Eurofins Megalab certificate, which is checked when boarding a plane. In the future, when the EU Digital Green Certificate begins to be used in Europe, the Trust One application can be used for arriving passengers.

At the end of February 2021, Austrian Chancellor Sebastian Kurz proposed introducing "green passports" in the EU countries for those who received the coronavirus vaccine. He admitted that such documents could be introduced at the national level. Chancellor Angela Merkel said that EU leaders agreed on the need to introduce electronic certificates for those vaccinated against coronavirus.^[1][2]
