With the rapid expansion of the Web3 ecosystem, a significant issue has emerged. It is the fundamental limitation that blockchains themselves cannot access external data. There are countless cases where smart contracts need real-world information to execute automatically—stock prices, weather data, insurance claim determinations, and more. Oracles serve as the bridge connecting on-chain and off-chain worlds.
Without oracles, smart contracts can only operate under preset conditions. However, the advent of decentralized oracles has led to innovative applications across various industries such as finance, insurance, and supply chain management. By enabling real-time data integration with smart contracts, a fully automated, trustless, and transparent ecosystem becomes possible for the first time.
How Decentralized Oracle Networks (DON) Work
Traditional data acquisition methods rely on a single source, making them vulnerable to attacks or failures at that point. In contrast, Decentralized Oracle Networks (DON) are advanced frameworks composed of multiple independent nodes. They fetch data from various sources simultaneously and verify it before recording on the blockchain. This approach significantly reduces risks like data tampering and single points of failure.
For contracts requiring complex and diverse data—such as weather conditions for agricultural insurance or price feeds for DeFi protocols—this decentralized mechanism is indispensable. Multiple nodes aggregate information and reach consensus, greatly enhancing the reliability of data supplied to smart contracts.
DON Operation Flow: Understanding in 6 Steps
The process by which decentralized oracles securely transmit data to the blockchain is realized through the following steps:
Request Stage - Smart contract requests data such as stock prices or weather information
Node Selection - Protocol selects a group of independent nodes
Data Collection - Each node retrieves data from assigned external sources
Verification & Aggregation - Nodes verify data and aggregate via consensus mechanisms
Data Transfer - Aggregated data is provided to the smart contract
Reward Distribution - Node operators receive rewards in the native token
Through this cycle, transparent and reliable decentralized data provision is achieved.
Five Key Roles of Oracles in Web3
Decentralized oracles are not just data intermediaries. They provide the following core values that underpin the Web3 infrastructure:
1. Innovation in Security and Reliability
Decentralized oracles leverage multiple independent data sources, significantly reducing risks of tampering and single points of failure. This enhances the overall security performance of dApps.
2. Real-Time Data Integration
By synchronizing smart contracts with real-world events and information, groundbreaking use cases such as live trading, instant settlement, and automatic insurance payouts become feasible.
3. Improved Data Accuracy
Aggregating data from multiple sources yields far more accurate and trustworthy information than relying on a single source, benefiting fields like DeFi, insurance, and supply chain management.
4. Cross-Chain Interoperability
Enabling seamless information exchange across different blockchains, with easy customization according to each chain’s characteristics, thereby increasing overall Web3 flexibility.
5. Transparency and Community Governance
All oracle operations are auditable on the blockchain, and many networks implement DAO governance. Token holders participate in democratic decision-making processes.
