The Central Bank of Brazil (BCB) has officially launched the second phase of its central bank digital currency (CBDC) pilot program, Drex, marking a pivotal advancement in the nation’s financial digitization strategy. This new phase focuses on expanding institutional participation, advancing asset tokenization infrastructure, and strengthening privacy through cutting-edge zero-knowledge (ZK) cryptographic solutions. With a clear roadmap and open call for proposals, Brazil is positioning itself as a Latin American leader in blockchain-enabled finance.
First-Phase Pilot: Laying the Foundation for Tokenized Finance
The initial stage of the Drex pilot brought together 16 consortia, primarily led by major Brazilian banks, to explore the feasibility of tokenizing real-world assets on decentralized networks. These early experiments have proven instrumental in identifying practical use cases and technical requirements for a scalable, secure digital currency ecosystem.
To date, 13 confirmed use cases have been developed and tested under the first phase, demonstrating the versatility of blockchain technology across multiple financial sectors:
- Tokenization of bank deposits – Enabling instant settlement and programmable money features.
- Bond tokenization – Streamlining issuance, trading, and redemption processes.
- Accounts receivable distribution – Improving liquidity and transparency in corporate finance.
- Mortgage loans via Brazil’s National Development Bank (BNDES) – Digitizing long-term credit instruments.
- Loans backed by government bonds – Creating secure, collateralized lending mechanisms.
- Trade finance optimization – Reducing delays and fraud in international commerce.
- Foreign exchange market efficiency – Facilitating faster cross-border settlements.
- Public debt liquidity pools – Enhancing market depth for government securities.
- CCB transactions – Tokenizing Cédulas de Crédito Bancário, a unique Brazilian financial instrument where businesses issue secured debt notes to banks with flexible terms.
- Agribusiness asset tokenization – Representing farmland, machinery, real estate, and crop inventories as digital tokens for trading and financing.
- Asset registration on public networks – Recording ownership of real estate, intellectual property, and financial instruments on decentralized ledgers.
- Multi-asset decentralized trading – Supporting peer-to-peer exchange of cars, carbon credits, bonds, and real estate through smart contracts.
These trials have not only validated technical feasibility but also highlighted regulatory, operational, and privacy challenges that must be addressed—setting the stage for a more robust second phase.
Second Phase Goals: Scale, Sophistication, and Security
The Drex pilot’s second phase aims to significantly expand both the number of participating institutions and the complexity of supported applications. The Executive Committee (CEG) is now accepting proposals from qualified financial entities between October 14 and November 29, inviting innovative business models that align with Brazil’s vision for a tokenized economy.
Each submission must include a detailed use case, technical architecture, and risk assessment. Proposals will undergo rigorous evaluation based on innovation, scalability, compliance, and interoperability before being selected for live testing.
A key focus area in this phase is privacy enhancement. While blockchain offers transparency, financial transactions often require confidentiality. To balance these needs, participating organizations are required to integrate advanced privacy-preserving technologies such as:
- Zether – A privacy protocol enabling confidential payments on public blockchains.
- Starlight – A framework for private smart contract execution.
- Rayls – A privacy layer designed for enterprise blockchain environments.
- ZKP Nova – An implementation of zero-knowledge proofs (ZKPs) allowing transaction validation without revealing sensitive data.
These tools ensure that transaction amounts, sender/receiver identities, and other critical data remain encrypted—even on public or semi-public networks—while still enabling auditability and regulatory oversight when necessary.

Why Privacy Matters in CBDCs
One of the biggest concerns surrounding central bank digital currencies is user privacy. Unlike cash, digital transactions can be tracked, raising fears of surveillance and data misuse. By incorporating ZK cryptography and other privacy layers, Brazil is addressing these concerns head-on—building public trust while maintaining compliance with anti-money laundering (AML) and know-your-customer (KYC) regulations.
Zero-knowledge proofs allow one party to prove the validity of a statement without revealing the underlying data. For example, a user can prove they have sufficient funds for a transaction without disclosing their balance. This capability is crucial for enterprise adoption and consumer acceptance alike.
Building a National Tokenization Infrastructure
Beyond payments, Drex represents Brazil’s broader ambition to build a national tokenization infrastructure—a unified framework where traditional assets can be digitized, fractionalized, and traded efficiently.
Tokenization unlocks numerous benefits:
- Increased liquidity for illiquid assets like real estate or agricultural commodities.
- Lower transaction costs through automation and disintermediation.
- Greater financial inclusion, enabling smaller investors to access high-value assets via fractional ownership.
- Improved audit trails and reduced fraud through immutable record-keeping.
For a resource-rich country like Brazil—with vast agribusiness, energy, and mining sectors—this infrastructure could unlock billions in trapped capital and attract global investment.
Moreover, integrating Drex with existing systems such as Pix (Brazil’s instant payment platform) could create synergies that boost adoption across retail and institutional markets.

Frequently Asked Questions (FAQ)
Q: What is Drex?
A: Drex is Brazil’s central bank digital currency (CBDC) pilot program led by the Central Bank of Brazil (BCB). It explores the use of blockchain technology for digitizing real-world assets and improving financial infrastructure.
Q: How does Drex differ from cryptocurrencies like Bitcoin?
A: Unlike decentralized cryptocurrencies, Drex is issued and regulated by the central bank. It is pegged to the Brazilian real and designed to coexist with physical cash and traditional banking systems.
Q: Is Drex available to the general public?
A: Not yet. Drex is currently in a pilot phase involving selected financial institutions. There is no official timeline for public rollout.
Q: What role do zero-knowledge proofs play in Drex?
A: ZKPs enhance transaction privacy by allowing verification without exposing sensitive data—such as amounts or parties involved—helping protect user confidentiality while ensuring regulatory compliance.
Q: Can I invest in Drex?
A: No. Drex is not an investment product. It is a digital form of sovereign currency under development for potential future use in payments and asset settlement.
Q: How does asset tokenization benefit the Brazilian economy?
A: Tokenization increases liquidity, reduces transaction costs, enables fractional ownership, and opens new financing avenues—especially valuable for sectors like agriculture, real estate, and infrastructure.
Final Thoughts
Brazil’s second-phase Drex initiative reflects a strategic, forward-thinking approach to financial modernization. By combining asset tokenization with strong privacy protections, the BCB is building a resilient foundation for a more inclusive, efficient, and secure financial system.
As global interest in CBDCs grows—from China’s e-CNY to Europe’s digital euro—Brazil stands out for its emphasis on practical use cases and technological innovation. The success of Drex could serve as a model for emerging economies seeking to harness blockchain without compromising stability or privacy.
With proposal evaluations underway and new pilots expected in 2025, the next 12 months will be critical in shaping the future of money in Brazil—and potentially beyond.
