O-Chain (Oracle)

Decentralized oracle with observe-commit-aggregate pipeline. Median, TWAP, and weighted aggregation with ZK proofs and quorum certificate attestation.

Chain Overview Explorer Source

Overview

The Oracle Chain provides decentralized price feeds and external data to all Lux chains through a three-phase pipeline: observe, commit, and aggregate.

Data providers submit observations that are committed on-chain and aggregated using configurable strategies — median, TWAP, or weighted averages. ZK proofs ensure data integrity, and quorum certificates attest to the validity of each aggregation round.

Unlike off-chain oracle networks, the O-Chain runs as a native Lux blockchain, inheriting the same security guarantees and finality properties as all other chains in the network.

Example

import { OracleClient } from 'luxnet/oracle'

const oracle = new OracleClient('https://oracle.lux.network')

// Get latest price feed
const price = await oracle.getPrice('LUX/USD')
console.log(`LUX price: $${price.value} (round ${price.round})`)
