he Central Bank of Brazil published yesterday on GitHub the guidelines with which more than 16 companies will participate in the tests of the Real Digital, the national currency or CBDC that is under development in Brazil.

Now, the Kit Onboarding – Real Digital Pilot repository has the development project available that anyone can access.
The documentation presents the architecture defined for the pilot, the topology and other details that participants must take into account for the start of the next Real Digital testing phase, scheduled for this month of July.
So the 16 corporations, companies and banks that will participate in the Real Digital tests already have the necessary information to configure and implement the nodes with which they will connect to the network.
In this phase of the Real Digital project, the privacy and programmability functionalities will be tested through the implementation of one of the 13 use cases provided by the Central Bank. This is a delivery-versus-payment protocol for federal public security between clients of different institutions.
Among the financial institutions and companies selected to carry out tests are Bradesco, Nuclea, Nubank, Banco Inter, Microsoft, Santander, Itaú Unibanco, as well as Visa and Mastercard.
After Banco do Brasil published the Real Digital guidelines on GitHub, some Brazilian users of the platform have begun to voice their concerns and make requests.
One of them asked if “will the addresses and the source code of the contracts be made publicly available?”.
Shortly after, another person pointed out: "I wish you would share the source code, because after all, this project was created with public resources and should be open for everyone to audit and suggest improvements," he says.
This user also shared a website that shows the initiative of thousands of people and multiple organizations in Europe, who ask that technological projects that are supported with public money be open source.
The proposal maintains that projects paid for by citizens must be available to all” and also “be more transparent”.
