Decentralized Oracle (DEOR) is a fully decentralized oracle aggregation network. It aims to link the on-chain and off-chain worlds in a secure manner. The off-chain component of the DEOR network is the oracle node. It is connected to the Ethereum network, and it will support all leading smart contract networks. The DEOR oracle nodes are powered by the standard open-source core implementation, which handles standard blockchain interactions, scheduling, and connecting with common external resources.
