Hamsa collaborates with Microsoft to solve privacy for the DREX platform, the CDBC project of the Central Bank of Brazil. Collaborators announce Hamsa Privacy – built on Microsoft's zero knowledge proof system.

Hamsa, a global blockchain and tokenization solutions company, is excited to announce its official collaboration with Microsoft to enhance the secure and scalable privacy solution for the Central Bank of Brazil’s Drex platform, the CBDC (Central Bank Digital Currency). The relationship combines the expertise of one of the world’s leading technology providers with the innovation of one of Silicon Valley’s best blockchain companies to deliver a stable, secure and innovative solution. Hamsa Privacy - built on Microsoft’s zero-knowledge proof-based privacy solution and solves the Central Bank of Brazil’s (BCB) “trilemma” of privacy, decentralization and programmability, in addition to other features such as interoperability and being EVM (Ethereum Virtual Machine) compatible.

This innovative privacy solution is changing the distributed ledger technology (DLT) sector in Brazil and worldwide, focusing on privacy solutions for central bank CBDCs, as well as payments, trading, settlement and reconciliation for global financial institutions. It is the only solution created for the Drex platform that uses a two-layer architecture that compresses data between layers, combined with Microsoft's privacy solution, to create high performance for wholesale and retail environments. With this solution, it will be possible to maintain programmability and have privacy in delivery versus payment (DvP) transactions and interoperability of the Drex platform with other blockchain networks in a scalable way.

Since last year, specialized global teams from Hamsa and Microsoft, including researchers,cryptographers and blockchain experts, have been working together to test and implement zero-knowledge proof as a ZK-rollup for privacy (layer 2). As Microsoft’s zero knowledge proof system is one of the solutions approved for review and testing by the Central Bank for use in Phase 2 of the Drex pilot, Hamsa and Microsoft will work closely with the BCB and pilot participants to ensure that the privacy solution exceeds the requirements set by the BCB.

“We are excited about the initial tests that have been conducted, and that it is a favorable solution for implementation in global CBDC environments and in DREX. This collaboration allows us to combine our deep knowledge and experience in blockchain and tokenization with Microsoft’s global platform, creating solutions that set new standards for security and privacy in the industry. We will bring innovative security and privacy solutions to the market together with the Hamsa interoperability solution, ensuring that our customers, whether wholesalers or retailers, can operate with confidence in an increasingly integrated and interoperable digital world,” said Henrique Teixeira, Hamsa’s MD for the Americas.

As part of the collaboration, Hamsa will be responsible for developing, implementing, and integrating the privacy solution with the BCB and participating financial institutions regulated by it. Microsoft will be responsible for providing its privacy solution based on zero-knowledge proof and layer-1 verification system (Hyperledger Besu).

In 2025, Hamsa will clear over $400B on its Universal Confidential Ledger, a EVM compatible ledger which is an extension of its Privacy Platform to ensure bank privacy, interoperability, programmability, and speed. Working with Brazil's major S1 and S2 banks, the Brazilian Central Bank, and serving some of the world's largest financial institutions, Hamsa provides infrastructure, digitizing and automating banking operations, transforming the way money, data and assets flow around the world with an unparalleled global presence and unique rich data tokenization technology. Hamsa Brasil is part of the Hamsa Global Digital Asset Network, which covers the United States and Asia, providing the world's largest financial institutions with highly interoperable, private, secure, and scalable digital ledger technology (DLT)solutions.
