Decentralized secure crowdfunding media platform
Working but buggy

"NuMedia" - is a decentralized secure crowdfunding media platform, which works with NuCypher technology and Ethereum blockchain.

For example, famous writer wanna run crowdfunding campaign for his new book. He can load demo data and encrypt it with NuCypher. After that he activate his campaign and deploy smart contract with all information into public ethereum blockchain. All transactions we can see on Etherscan. After that everyone can see all neccessary information about his book, everyone can support it and watch demo data, which he secure shares with NuCypher technology.

How does crowdfunding process work? SmartContract sales exclusive tokens, which everyone can by for ethereum coins. When somebody decide to support my product, he will send some amount of ethereum to the smartcontract and get this tokens. Crowdfunding campaign is successfull when more, than 50 percent tokens are saled. In this case all reward transfer to my account from smartcontract. In another case, all balance of smartcontract returns to owners of exclusive tokens. It means, that everyone, who supported my project can delegate their ownership to another person and in this case blockchain with nucypher technology give us a guarantee that they will not have access to my release product.
- This is a safe method of interaction between the organizers and participants of the crowdfunding platform.
- Сrowdfunding member can track the seller’s progress in the development of a product and delegate his ownership to another person
- SmartContract gives money back guarantee to participants in case of campaign failure.

During this hackathon I've considered the project logic, implemented a first version of smart contract, integrated it with NuCypher technology and designed interface. For run this project in production I also need upgrade smartcontract functions, upgrade interface and test this system. It requires approximately 2 or 3 months.

Vladimir, yes. You need metamask extension and some ethereum for transaction (gas)

Ivan, can you give more infromation about errors/bugs/warnings? I've checked now all functionality and it works correctly. Notice: maybe you haven't got metamask browser extension or you haven't got enoughth gas to create transactions in rinkeby testnet.
