Brazil embraces the future with blockchain-based National Identity Program

In this post:

  • Brazil is launching a blockchain-powered national identity system, with Rio de Janeiro, Goiás, and Paraná as the first states to issue these digital IDs.
  • Alongside this, Brazil is delving into the realm of digital currency with its central bank digital currency project, named “Drex.”

In a groundbreaking move, Brazil is set to revolutionize its national identity system by integrating blockchain technology. This initiative, which aims to provide over 214 million Brazilians with a digital identity, is a testament to the nation’s commitment to technological advancement and security.

Initial rollout in Rio de Janeiro, Goiás, and Paraná

The Brazilian government recently unveiled its ambitious plan to launch a blockchain-powered national identity program. The states of Rio de Janeiro, Goiás, and Paraná have been chosen as the pioneers for this initiative, being the first to issue identification documents on the blockchain. This move is facilitated through a collaboration with Serpro, Brazil’s esteemed national data processing service.

A decree released on September 25th indicates that the entire nation is on track to have the capability to issue these blockchain-based identity documents by November 6th. This rapid rollout underscores the importance the Brazilian government places on modernizing its identification system and ensuring the security and authenticity of its citizens’ data.

Why blockchain? Insights from Serpro’s president

Blockchain technology, known for its immutability and decentralization, has been hailed as the perfect fit for Brazil’s digital identification project. Alexandre Amorim, the president of Serpro, shed light on this decision, emphasizing the unparalleled security features blockchain offers.

“Blockchain technology plays a pivotal role in safeguarding personal data and deterring fraudulent activities,” Amorim stated. “By leveraging the b-Cadastros blockchain platform, we are significantly bolstering the security and trustworthiness of the National Identity Card project.”

The national ID project is not just about modernization but also plays a strategic role in Brazil’s fight against organized crime. By providing a unified and secure identification system, the government aims to foster better collaboration between various sectors. This will not only streamline administrative processes but also offer citizens a more straightforward way to access essential services.

Interestingly, Brazil isn’t the only South American country exploring this avenue. Buenos Aires, the capital city of Argentina, recently unveiled a similar initiative. This program allows residents to obtain identity documents through a digital wallet, marking another step forward in the continent’s digital transformation journey.

Beyond identification: Brazil’s foray into digital currency

While the national ID project is making headlines, it’s not the only significant technological development in Brazil. The country is also making strides in the realm of digital currency. In August, the government shared more details about its central bank digital currency (CBDC) project, now rebranded as “Drex.”

This digital currency initiative aims to broaden business access to capital by introducing a tokenization system linked to the Drex. However, it hasn’t been without its controversies. Local developers discovered that the Drex code possesses functionalities that allow a central authority to freeze funds or even diminish balances. This revelation has sparked discussions about the balance between security and user autonomy in the digital age.


Brazil’s endeavors to integrate blockchain technology into its national identity system and its exploration of digital currency highlight the nation’s forward-thinking approach. As the world increasingly shifts towards a digital paradigm, Brazil’s efforts in these domains position it as a leader in technological innovation and security in South America. Only time will tell how these initiatives will shape the nation’s future, but for now, Brazil is undoubtedly on the path to a more secure and interconnected digital era.
