Oracles Secure The Data - Who Secures The Oracles?
summary
Three oracle models are defined: a centralized nuracle that hands a single entity the keys (examples include single‑coordinator VRF and many RWA feeds), an aggregator or multi‑party model used by MakerDAO, Augur and many Chainlink deployments, and truly decentralized systems like Witnet, Teller and CEDA that use secret random assignment plus commit‑reveal reporting and staking with slashing to produce provable data. Those decentralized nets run on a minimal layer‑1 sidechain, interoperate with support for 50+ EVMs, and advertise validator yields (~20% APY).
