Aeternity is a blockchain based cryptocurrency and smart contract platform. It also links smart contract with the real-world via a decentralized oracle.
An oracle is a tool that allow blockchains t
o learn the outcome of an event. Thus, they report something that happened in the past. Oracles are an important mean of tying together the blockchain and real-world data.
Aeternity is dedicated to make oracle services part of its core blockchain protocol, as the oracle itself is defined as an entity that exists on the blockchain, thus being cheaper and more flexible.
