Taurus SA, global leader in digital asset infrastructure, has announced the launch of an open-source privacy security token for the tokenization of shares and bonds, in collaboration with Aztec Foundation and Deutsche Bank.
This represents a step forward for institutional decentralized finance. In this article, we see all the details.
Taurus introduces an open-source security privacy token for banks: the importance of Deutsche Bank in the project
In the constantly evolving financial landscape, privacy and security have become fundamental aspects for the adoption of blockchain by institutions.
In response to this need, Taurus SA, a leading company in infrastructure for digital assets, has announced the publication of a new open-source standard for the private tokenization of financial instruments.
The token is developed in collaboration with Aztec Foundation. This initiative allows banks and financial institutions to issue tokenized versions of stocks and bonds on public blockchain, while ensuring the confidentiality of customer information.
The smart contract developed by Taurus is designed to offer asset issuers precise and detailed control over who can view information related to financial instruments registered on public blockchains.
Everything happens without compromising regulatory compliance, a crucial aspect for the integration of decentralized technologies in the banking sector.
At the core of this innovation is Aztec Network, a Layer-2 solution that uses zero-knowledge proofs (ZK-proofs) to keep transactions confidential. All of this without sacrificing the typical programmability of the blockchain.
This approach allows maintaining the privacy of operations, while providing the traceability and security required by financial regulations.
An advanced solution based on Noir and CMTAT
The code was written in Noir, an open-source language with a syntax similar to Rust, specifically designed for creating applications based on ZK-proofs.
This new standard implements a private version of the CMTAT, a security token that ensures protected and private transactions.
Thanks to this technology, banks and financial institutions can now leverage blockchain to tokenize assets without the fear of exposing sensitive data.
In a context where regulation is increasingly focused on privacy protection, Taurus offers a solution that combines transparency and regulatory compliance . This allows the financial sector to approach decentralized technologies with greater security.
The opinion of the experts
JP Aumasson, Chief Security Officer of Taurus, emphasized the importance of this innovation:
“The tokenization of financial instruments on public blockchains offers extraordinary potential. Thanks to private and compliant transfers, we bridge the gap between institutional needs and decentralized technologies. This project confirms Taurus’s commitment to providing secure and cutting-edge digital solutions.”
Arnaud Schenk, Executive Director di Aztec Foundation, also highlighted the value of this collaboration:
“Privacy is an essential element for the large-scale adoption of blockchain by financial institutions. The private CMTAT developed by Taurus represents an important milestone, demonstrating that it is possible to reconcile regulatory needs and on-chain innovation. Aztec develops cryptographic tools to bring real-world assets onto public blockchains since 2017, and we are excited to see Taurus leverage the potential of Noir and our Layer-2.”
To demonstrate its commitment to a more transparent and secure financial ecosystem, Taurus has made the open-source code available on GitHub for public access and testing.
This initiative not only promotes the adoption of blockchain in the banking sector, but also represents an important step forward towards the digitization of financial assets in a secure, regulated, and highly innovative environment.
