Brazil is using blockchain for National Identity Card (CIN) issuance to enhance security. A shared registration platform by Serpro facilitates data sharing between the RFB and OICs. The rollout begins in Goiás, Paraná, and Rio de Janeiro, with a nationwide deadline of November 6, 2023, according to Decree No. 10,977 of February 23, 2022.

The advantage of blockchain lies in its security features

Blockchain technology is vital for protecting personal data and preventing fraud in Brazil, thanks to the b-Registers platform. It ensures security, data immutability, and transparency, enhancing user trust.

Timelines for Implementation

The shift to blockchain for CIN issuance initiates in Goiás, Paraná, and Rio de Janeiro this week, with other states following in the next six weeks. By November 6, 2023, all issuing bodies are required to implement the new CIN standards, as mandated by the decree. Rogério Mascarenhas, the Secretary of Digital Government at the Ministry of Management and Public Services Innovation (MGI), underscores the critical importance of adhering to this timeline, emphasizing the substantial impact of the CIN project on public safety and the fight against organized crime.

Benefits Centered on Citizens

Since July last year, Brazil has issued the CIN with enhanced security features, including a secure QR code and a digital version on the Gov.br app. The CPF is now the national registration number for consistent citizen identification. This aligns with global trends, and blockchain technology has been instrumental in unifying identity issuance across Brazil’s states. The announcement coincides with Brazil’s exploration of a central bank digital currency (CBDC) named Drex, introduced in August for modernized and efficient public service delivery.
