Brazils CBDC Pilot Code: Revealing the Perplexing Power to Freeze and Reduce Funds

Brazilian CBDC Source Code Reverse-Engineered by Blockchain Developer

Blockchain developer Pedro Magalhães has successfully reverse-engineered the source code of Brazil’s pilot central bank digital currency (CBDC). Magalhães discovered functions that allow a central authority to freeze funds or adjust balances. While concerns have been raised about these capabilities, Magalhães believes there could be potential benefits in certain situations. The source code of the digital Brazilian real pilot project was published by the Banco Central do Brazil on July 6 for testing purposes. Magalhães, founder of Iora Labs, was able to expose various functions, including freezing and unfreezing accounts, transferring currency between addresses, and generating or eliminating digital real from specific addresses. However, he expressed concerns about the lack of explicit specifications regarding the circumstances for freezing tokens and the authority that can execute these actions.

Potential Benefits and Concerns Surrounding Brazil’s CBDC

While there are concerns about the authority and circumstances for executing functions such as freezing funds and adjusting balances, blockchain developer Pedro Magalhães suggests that Brazil’s CBDC could have potential benefits. He argues that a digital currency would enhance tax traceability, allowing the public to scrutinize the allocation of tax funds and monitor the government’s on-chain purchases. This increased transparency could improve parliamentary amendments. However, Magalhães also expresses concerns about the power of an institution to unilaterally freeze a user’s balance, highlighting the contrast between decentralized finance operations and granting authorities the ability to freeze funds.

Brazil’s CBDC Journey and Goals

The Central Bank of Brazil unveiled the participants for the Real Digital Pilot on May 24, with 14 chosen parties from over 100 institutions. Among the participants are Visa, Mastercard, Itaú Unibanco, and BTG Pactual. The CBDC, known as the digital real, aims to be pegged to the national fiat currency, the real, with a gradually increasing fixed supply. Fabio Araujo, the project coordinator, sets a goal for widespread adoption of the digital real among the general population by the end of 2024.

Hot Take

While concerns about the authority and circumstances for executing functions like freezing funds or adjusting balances are valid, there is potential for Brazil’s CBDC to offer benefits. Increased traceability and transparency in tax allocation and government purchases could lead to more accountable and efficient governance. However, it is crucial to establish clear guidelines and limitations on the authority to freeze funds to prevent abuse of power and protect individual rights. Striking the right balance between decentralization and centralized control will be essential for the successful implementation of Brazil’s CBDC.
