On Thursday, the Sui Foundation announced via X that Custom PCR verification is now live on Sui mainnet. Marlin Nautilus enclaves can attest onchain, letting apps prove their TEE code is untampered and secure.
Thanks to this support, developers building confidential apps on Sui can now easily prove the code running in TEEs is untampered and secure. Previously, builders needed to manage cloud accounts, networking, enclave images, and attestation servers. Oyster removes this barrier while preserving cryptographic guarantees through Nautilus.
A TEE, such as AWS Nitro Enclaves prevents tampering through memory isolation, restricted I/O, and cryptographic measurement (PCRs), and the TEE generates a cryptographic attestation proving exactly what binary is running inside. TEEs provide a practical way to balance performance, confidentiality, and verifiability for offchain workloads.
Sui's Nautilus framework enables verifiable offchain computation. Developers can delegate complex tasks to an offchain TEE while maintaining cryptographic trust onchain through reproducible builds and verifiable attestation. Nautilus provides the foundation for verifiable offchain computation on Sui, enabling secure and attestable interactions between TEEs and Move smart contracts.
With the integration, developers can access confidential compute without the operational overhead of managing AWS infrastructure. Nautilus provides the cryptographic foundation for hardware-backed proof. Marlin Oyster provides the execution layer that transforms this into a decentralized marketplace.
Sui is a Layer 1 blockchain designed to provide top-notch developer and user experiences backed by robust technological foundations. SUI is up 3% in the last 24 hours, trading at $0.9442 per coin.
