" summary

Describes a deployed oracle middleware, Chainlink, that turns off‑chain APIs and payment rails into on‑chain inputs and outputs by running decentralized middleware across multiple nodes and using an adapter model to plug into Ethereum, Polkadot, Hyperledger, Bitcoin, Zcash and APIs. Claims use of Intel SGX (Town Crier) for trusted execution when single sources exist, broadcasts one oracle contract per parachain now and plans a dedicated oracle chain later, and reports live integrations for price feeds, payments and delivery triggers.
