FlightSurety

FlightSurety is a sample application based on smart contracts running on the Ethereum blockchain.

Passengers can purchase flight insurance, airlines can register new airlines and flights. Oracles simulate insurance case after which passenger can get a payout.

This project was developed as part of Udacity's Blockchain Developer Nanodegree Program.

dApp Screenshots

Accounts registered as airline can register flights and new airlines. Registration of fifth and subsequent airlines requires multi-party consensus of 50% of registered airlines. So airline accounts can access the voting.

Passengers can purchase insurance, invoke the simulation of flight fault due airline company and then get a payout.

Flights and airlines are statically programmed. The list with allowed for registration flights and airlines is printed in the developer console.
