How Do Decentralized Oracle Networks (DONs) Improve Data Integrity for Smart Contracts?

DONs improve integrity by sourcing data from multiple independent nodes and aggregating it using cryptographic methods, such as a median or weighted average. This decentralization makes it exponentially harder for a single entity to corrupt the data feed.

The consensus mechanism among the nodes ensures that the final data delivered to the smart contract is robust, reliable, and resistant to single-point-of-failure attacks.
