On April 17, it was announced that as a powerful new member of the Sui security toolkit, Nautilus is now online on the Sui testnet. Nautilus is specially built for Web3 developers, allowing developers to perform sensitive or computation-intensive operations in a self-managed, isolated and tamper-resistant Trusted Execution Environment (TEE) mid-chain and offline. At the same time, these TEEs can generate cryptographic certificates to ensure that the calculation process is authentic and trustworthy. Applications or users can submit calculation results to the chain, and the Move smart contract will verify these certificates before processing them. Currently, developers can now experience Nautilus on Sui testnet. The GitHub codebase already includes reproducible templates for building, deploying, and registering self-hosted AWS Nitro Enclave, as well as a reference app that demonstrates the complete process from generating trusted certificates to on-chain verification. This release marks another important milestone for Sui in supporting privacy protection and verifiable off-chain computing, allowing it to build privacy-first security applications, such as tamper-proof real-world data oracle, autonomous proxy process and on-chain traceability, hidden logic and metadata for fair play Web3 games, privacy authentication without exposing user information, etc.
