Introduction

In ancient India an oracle was referred to as Akashwhani, which means a voice without a body, unseen, or a voice coming from the sky... That is why we have called this hackathon the Akashwani Hæck, an unseen voice going straight into the blocks!

Oracles, in the blockchain sense of the word, are an important part of the technological stack required for a wide variety of decentralized applications. They are a link between the physical world and the virtual reality of blockchain platforms and an essential part of the promise of smart contracts.

What we are in fact talking about are tools that allow blockchains to learn the outcome of relevant events

All the applications running on a public blockchain usually require “triggers” in order to provide a service, usually in the form of an automated action. Some of these triggers could be coming from specific users — for example initiating a transaction or instructing a smart-contract. 

Others, however, rely on information provided by oracles, and æternity offers them out of the box for the best user experience, but also for the best developer experience, security and optimization of costs.
