Building confidentiality into capital markets standards: CMTAT Confidential launches on the Zama Protocol
Blog post from Zama
The Capital Markets and Technology Association (CMTA) has introduced CMTAT Confidential, enhancing its security token standard by integrating confidential transactions and balances through the Zama Protocol, which utilizes Fully Homomorphic Encryption, Multi-Party Computation, and Zero-Knowledge Proofs. This development addresses one of the key challenges faced by regulated financial institutions using public blockchains: the visibility of every transaction and balance. CMTAT Confidential allows confidential financial operations without compromising compliance controls, maintaining governance features such as allowlisting and forced transfers. The initiative, developed in collaboration with industry leaders like Taurus and validated by entities such as Boerse Stuttgart Group, demonstrates that confidentiality is achievable and production-ready, providing a significant advancement for institutional onchain finance. The framework does not alter existing governance structures, ensuring that financial institutions can protect sensitive trading and client information while using blockchain technology for tokenized assets.
