sub0 Asia 2024 - Christian Langenbacher (Integritee)
summary
Claim: a TE-based system produces verifiable private random permutations using Intel SGX RNG and on-chain remote attestation verified by the Integritee network, removing reliance on the hardware vendor. Built components include an Integrity par chain pallet T‑Rex, a sidechain worker via the sidechain SDK, a confidential computing infra and attestation service. Demo runs a 200-entry raffle, draws two winners, publishes a Merkle root and signatures, and verifies proofs on-chain; the CLI demo succeeds and the stack claims up to 1 million tx/sec.
