Primus Labs: Beyond Privacy, Toward Private On-Chain Finance @primus_labs @KaitoAI Reviewing Primus Labs’ latest updates reveals a more concrete vision: Primus is not merely focused on data verification technology, but on creating an environment where personal data can be securely leveraged for real financial services. One of the most notable developments is its collaboration with Kaito. By integrating Primus’s zkTLS technology into Kaito Pulse and Aura for activity verification, users can now prove their activities on external platforms without exposing sensitive login credentials or account information. This bridges online activity and reputation through verifiable records—not just claims—making it a meaningful advancement. Another key update is the Primus Confidential Vault. Designed for the BNB Chain, this service employs Fully Homomorphic Encryption (FHE) to protect on-chain financial data. According to public documentation, users can convert $U into an encrypted asset, eU, then transmit or deposit it in encrypted form to earn yields, and convert it back when needed. The critical technology here is FHE—Fully Homomorphic Encryption. While traditional blockchains expose balances and transaction amounts publicly, FHE enables computations on encrypted data without decryption. Primus leverages this to preserve asset utility while minimizing unnecessary exposure of sensitive financial information. Earlier in October, Primus participated in events related to BNB Seoul, engaging with institutional finance and Web3 ecosystem participants to demonstrate how on-chain finance can simultaneously achieve privacy and verifiability. This underscores Primus’s commitment not only to technological development but also to real-world integration within the financial ecosystem. On the development front, ongoing updates include the zkTLS SDK and browser extensions. When zkTLS—used to verify the authenticity of off-chain web data—is combined with FHE for processing encrypted data, it opens the door to a wide range of services that safely leverage Web2 information within Web3 while reducing exposure of financial data. Of course, for privacy-preserving technologies to be widely adopted in real financial services, challenges around security, processing speed, usability, and regulatory compliance must still be addressed. The mere existence of technology does not automatically guarantee service safety. What stands out most about Primus Labs is its approach: not simply hiding data, but enabling financial activity by verifying necessary information while protecting sensitive details. From Kaito’s activity verification to private finance via the Confidential Vault, the key watchpoint moving forward will be how broadly Primus can expand its real-world use cases.
