Etherwave

Idea

An app to book concert tickets via ethereum and also allow users to trade their tickets among themselves.

Etherwave is an authentic adaptation of Lev Termen's original design for the Theremin and also a cool project name for a hackathon adding music on ethereum blockchain.

The user own the ticket

The users have easy access to their tokens through Etherwave app
They are free can transfer in any ERC721 exchange
They can be easily verified by anyone through the QR Code and comparing to the information registered in the blockchain

No more endless lines!

No paperwork needed
Just needs one time verification
Any trade can be done in a safe way
No more gatecrasher

ERC721

ERC721, also known as NFTs (Non-fungible token) are tokens where each one is unique. These individual tokens can come with metadata, which would be a link for their IPFS json file. In this project we have added events' info to the blockchain such as location, date and price of event. They're indivisible unlike fungible tokens.

Usage

The Tickets for every event stored in a blockchain are all ERC721(Non-Fungible) tokens The user can buy them for an event and in case the user is not able to attend the event, he/she can sell it to other users for price equal or more than original.
