gm all .... let's assume a DeFi lending protocol wants to know whether a user exchange account balance has exceeded $10,000. the information is stored on a centralized website, but the final decision must be made on the blockchain without requiring the user to disclose all their account information. this is where the infrastructure provided by @primus_labs becomes valuable. however, generating a valid proof does not depend on cryptography alone, several different steps must work correctly for web data to become a trustworthy input for a smart contract. the first step is establishing a valid session. the user logs into the website with their own account, and a secure TLS connection is established. using zkTLS, Primus attempts to prove the information received through this connection in a verifiable way, without requiring the website's cooperation or changes to its infrastructure. in the next step, the required field, such as the account balance, must be correctly extracted from the web response. Primus supports two methods, MPC and Proxy, which differ in terms of speed and trust assumptions. if the field is extracted incorrectly or the session is not processed properly, even a cryptographically correct process will not necessarily produce the result the application needs. in the third step, the proof must demonstrate that the data came from the intended source and has not been tampered with. Primus also uses TEE to protect the execution integrity of the Attestor software. however, this layer does not eliminate all trust assumptions; the security of the TEE and its supporting infrastructure also matters. the contract must verify the proof and use the result according to the application's logic. if the contract validation is incomplete, the wrong field is checked, or the data is no longer valid for the intended decision, the correctness of the previous steps alone is not enough. this is the key point, the validity of a system does not depend solely on the strength of its cryptographic proofs, but also on the correctness of the entire process of generating and using those proofs. to evaluate this kind of infrastructure, we need to examine not only protocol security, but also the correctness of data extraction, trust assumptions, contract implementation, and system behavior under failure conditions. s.kaito.ai/7F6dI7N
