State of Oracles in the Space
summary
Overview of concrete oracle designs and tradeoffs: lists include centralized providers (Provable/Oraclize), multi-signer feeds, relayered aggregation, delegated PoS with staking and slashing, prediction-market resolution, and cryptoeconomic consensus approaches used by Teller. Notes that Maker’s 1-hour delay saved it on Black Thursday and that Chainlink currently whitelist nodes rather than the whitepaper model. Claims the oracle space faces a clear scalability trilemma — faster feeds sacrifice decentralization or cost — and urges choosing design by explicit threat and liveness models.
