Build Tamper-Proof Oracles with Nautilus on Sui Mainnet

Nautilus, a crucial piece of Web3 infrastructure, is now live on Sui Mainnet. This platform enables developers to offload app-specific offchain computations to tamper-proof Trusted Execution Environments (TEEs), combining the flexibility of offchain logic with the cryptographic trust guarantees of onchain execution. Traditional offchain computations, such as those used by oracles to bring external data onchain, often rely on closed-source infrastructure, requiring users to trust the data processing and delivery without verification. Nautilus addresses this issue by allowing developers to create oracles and offchain flows that are tamper-proof and verifiable onchain, ensuring data integrity and trust.

Key Ideas

1. Nautilus uses TEEs, starting with AWS Nitro Enclaves, to enable secure offchain computation in Web3. Each Nautilus enclave runs specific, publicly auditable code that is cryptographically measured, ensuring transparency and integrity.

2. Developers can build secure oracles with Nautilus by writing data-fetching logic, deploying it to a Nitro Enclave, registering the enclave on-chain, fetching and signing external data, and submitting the result to Sui for verification. This foundation can be adapted to various use cases, including price feeds, reputation systems, geolocation-based NFTs, and trust-minimized social-linked flows.
