kTLS and FHE are both privacy technologies—why are they needed together? When studying privacy-related projects, you’ll frequently encounter terms like zkTLS, ZK, and FHE. All are cryptographic technologies, but they address fundamentally different problems. Understanding this distinction makes the architecture of @primus_labs much clearer. Let’s imagine a hypothetical scenario: A person holds $100,000 in a centralized exchange and wants to use on-chain financial services based on these assets. However, two distinct problems arise here. The first is verification: “Does this person truly hold $100,000 on the exchange?” This is where zkTLS comes in. zkTLS cryptographically verifies that data delivered via HTTPS genuinely originates from the server’s response. It allows you to expose or verify only the necessary data, minimizing exposure of financial information. The second is computation: “Can we perform computations using this verified sensitive data without revealing its contents?” This is where FHE enters the picture. FHE is a technology that enables computation on encrypted data. It supports confidential operations when using verified data within financial applications. To summarize, their roles differ: zkTLS addresses the question: “Where did the data come from, and what response was received?” FHE focuses on: “How can we compute with sensitive data without exposing it?” Taking it one step further, the concept of zkFHE emerges. While standard FHE provides data confidentiality, zkFHE also addresses whether the encrypted computation result is correct. However, as noted in Primus’s official documentation, zkFHE is still in the R&D phase, with significant challenges remaining before it reaches commercial readiness. Can we trust the data? Can we protect the data? Can we trust the computation result? These three questions may seem similar, but they represent distinct technical challenges. When understanding Primus, it’s more useful to connect these three questions than to focus solely on the names of individual technologies. #Primus #zkTLS #FHE #zkFHE
