Primus: From finance based on trust to verifiable finance @primus_labs @KaitoAI Trust has always been a critical issue in blockchain. Just because transaction histories are public does not mean all information is accurate. Especially for exchange reserves, financial institution assets, or data sourced from external platforms, it is essential to verify where the information actually originates. To address these challenges, primus_labs focuses on data verification and privacy. Primus’s core technologies are zkTLS and zkFHE. First, zkTLS enables cryptographic verification of external data sourced via HTTPS. When users need to prove their financial information or transaction history, they can confirm that the data comes from a trusted source without revealing the full original dataset. The key here is balancing truth verification with privacy protection. zkFHE takes this a step further: it allows computations to be performed while keeping data fully encrypted. This structure enables necessary validation and calculations without exposing sensitive financial information to external parties. A recent notable example is Proof of Reserves. Primus collaborated with Brevis to build the reserve verification system for Perena’s USD*. Primus’s zkTLS verifies the origin and authenticity of external data, while Brevis’s Pico zkVM generates verifiable proofs based on that data. A similar architecture is also used in Unitas’s USDu reserve verification. What’s particularly interesting is that it extends verification to include off-chain hedging positions held at centralized exchanges, not just on-chain assets. This structure matters because there is a fundamental difference between simply publishing numbers and providing verifiably accurate information. In the future, these technologies can expand beyond reserve proofs to areas such as credit scoring, P2P payments, institutional finance, and data verification for AI agents. There are three aspects I consider vital at Primus: First, source verification—confirming where data originates. Second, privacy—proving necessary facts without exposing sensitive information. Third, connecting verified data to real-world financial services and AI agents. As financial markets expand on-chain, problems will arise that cannot be solved by blind transparency alone. The growing importance lies in environments where necessary facts can be proven without revealing all information—and where confidence comes not from trusting someone’s word, but from cryptographic evidence. I believe Primus’s mission is to make trust verifiable through technology, not just words.
