DEOR is a fully decentralized oracle network featuring randomness, reputation, and security monitoring systems. DEOR represents the next generation of oracle systems, overcoming the oracle problem by aggregating multiple oracle sources. By bringing information from multiple perspectives, DEOR eliminates potential biases and manipulations, providing higher quality data to blockchains. Operating in a decentralized manner, DEOR employs a dynamic reputation and rating system that allows users to increase or decrease the reputation and weight of individual predictions based on behavior during the data collection process.
