Last updated 12 days ago

Instead of distributing pre-calculated data feeds, the DIA Nexus system covers the whole data journey from individual trade information collection, and data computation to the last mile of the feed delivery. To create, for instance, an ETH/USD price feed oracle, Nexus sources data points from dozens of ETH pairs (ETH/USD, ETH/USDT, ETH/BTC, etc) trades from across a wide range of exchanges.

Learn the layers of data aggregation, filtering, and computation that ensure highly accurate and resilient feeds for dApps.
