Astraea a decentralized blockchain oracle In he was a visiting faculty at the University of Illinois until when he joined the Department of Electrical and Computer Engineering and the Department of Computer Science at the University of Toronto where today he is a Professor. After a proposition has accumulated a certain number of votes, it is decided as either true or false based on the voting results, and rewards and penalties are administered to participating voters and certifiers. Shankar, PhD Imran Bashir. As such, the equilibrium in which all participants behave honestly is expected to maximize rewards. In its original application, it allows a set of quasi-anonymous and mutually-distrusting parties to reach consensus on the ordering of monetary transactions.

The mechanism driving voter incentives is resistant to adversarial manipulation. Augur [7] is a prediction market with a built-in voting-based oracle to determine the outcome of events in order to pay out market participants. Need Help?

What are Oracles in Crypto? (Animated)
Trusted entities that fetch external data onto blockchains are called oracles. The ASTRAEA protocols [6], [7] is a series of decentralized blockchain oracle. Abstract: The public blockchain was originally conceived to process monetary transactions in a peer-to-peer network while preventing double-spending.

Zoltu, A. Submitters are clients who need to learn the outcome of Boolean propositions. A voter is rewarded for her vote on a particular proposition if it agrees with the majority of votes and certifications explained below for that proposition. By combining these two mechanisms, Astraea can achieve a high degree of resistance to adversarial manipulation and degenerate equilibrium behavior.
