Primus Labs, formerly known as PADO, is a cryptographic infrastructure platform dedicated to enhancing data interoperability between Web2 and Web3 systems. By leveraging advanced cryptographic technologies such as zero-knowledge Transport Layer Security (zkTLS) and zero-knowledge Fully Homomorphic Encryption (zkFHE), Primus enables secure, permissionless data verification and computation. This approach allows developers to seamlessly integrate off-chain data with blockchain and AI applications, ensuring data authenticity and privacy without exposing sensitive information.
