The Future of Data Feeds
Oracle demand is expanding beyond crypto spot prices. Tokenized treasuries need NAV attestations. Insurance needs verified weather and IoT readings. AI-native apps want model outputs with dispute windows. Intent-based protocols want prices synchronized across chains in the same block users sign for.
Real-world asset platforms already blend custodian attestations, rating agency inputs, and on-chain proof schemas — closer to capital markets data than DEX mid prices. Privacy-preserving oracles and optimistic verification may let sensitive data publish commitments first and reveal details only when disputes arise.
The constant through all of it: blockchains still will not fetch the outside world on their own. Better economics, cryptography, and tooling change how oracles work — not whether your protocol needs to think critically about the data it trusts.
