Ethereum Dapp for Flight Surety

This project was developed as part of the Udacity Blockchain Developer Nanodegree Program

FlightSurety is a decentralized application where passengers can buy flight insurance. The flow is the following:

For Airlines:

• Airlines can be registered to be part of the insurance program
• Airlines need to deploy 10 ETH to the contract to get activated
• Airlines can register flights in the contract

For Passengers:

• Passengers can buy flight insurance for up to 1 ETH
• If the flight is delayed because of the airline the passenger gets 150% of his depost
• Passengers can withdraw their funds at any time

Consensus:

Consensus on the flight status is achieved by oracles.

• Oracles can register to take part of the flight status voting.
• Oracles need to pay a registration fee of 1 ETH.
• Oracles get asked for their input on flight status after the flight has arrived.
• The flight status is determined by majority vote.
• In case the flight was delayed all insurees get credited.
