How Does a “Decentralized Oracle Network” (DON) Achieve Data Security and Reliability?

A DON achieves security and reliability by aggregating data from multiple independent, vetted data sources and nodes. It uses cryptographic proofs and consensus mechanisms to validate the data, eliminating single points of failure and making manipulation extremely costly.

The final, validated data is then submitted on-chain, ensuring that the smart contract receives a tamper-proof, accurate, and robust price feed.
