Sui

🧱 Bring your TEEs to Sui. Introducing Nautilus.

Confidential computing is here — and it’s fully verifiable.

Build hybrid Web3 apps that are fast, private, and decentralized.

Now live on Testnet.

Nautilus lets you process private data or run high-cost logic offchain in self-managed Trusted Execution Environments (TEEs) — starting with AWS Nitro Enclaves.

Then it anchors trust onchain using cryptographic attestations, verified by Move smart contracts.

Low cost computation offchain. High trust verifiability onchain.

✅ How it works:

• Deploy your logic to an offchain TEE (e.g. Nitro Enclave)

• The TEE executes it & produces a cryptographic attestation

• Onchain Move smart contracts verify the attestation before accepting TEE outputs

TEE integrity is auditable and anchored to provider’s root of trust

Why it matters:

Web3 isn’t about doing everything onchain — it’s about verifiable computing across both onchain and offchain layers to strike the optimum balance.

Nautilus enables a new class of hybrid apps:

Private. Performant. Decentralized.

🔒 Use cases for Nautilus:

• Tamper-proof offchain oracles (prices, weather, sports)

• Secure AI inference with offchain privacy + onchain provenance

• Private identity checks with onchain verification

• Hidden and computationally intensive game logic for fair play

Combine Nautilus with Seal for full-spectrum privacy:

🧠 Process private data offchain with Nautilus

🔐 Encrypt the output with Seal and store on public network

🔓 Decrypt it in a dApp or another Nautilus enclave  — only if Seal access conditions are met

🧰 Dev toolkit includes:

• Onchain Move modules for verifying offchain attestations

• Reproducible build template for AWS Nitro Enclaves

🛡️ Part of Sui’s trust-by-design architecture:

• Object-centric data model for secure onchain state

• Move for safe and auditable smart contracts

• zkLogin: Web2-style auth with zero-knowledge privacy

• Passkey based seamless login flow without seedphrases

• Onchain randomness

• Native support for zk-SNARKs

• Seal for decentralized encryption + access control

With Nautilus, Sui brings verifiable offchain computation into the core Web3 developer toolkit.

The future of Web3 is hybrid.

Offchain privacy. Onchain trust.

Now you can have both.
