Uploaded photo watermarked by Stock Block
Inspiration
We want photographers or artists to make all of the money when they sell their photos.
What it does
It allows people to upload and buy photos. Ethereum is used as a payment tool between transfers.
How we built it
We used the embark framework to compile and migrate our solidity contracts to the blockchain and testrpc for the blockchain which also manages the accounts. We used MetaMask to manage the accounts and balances. IPFS (Interplanetary File System) to store the pictures and produce hashes of them to get later. Javascript and HTML was used to create the webpage and communicate with the smart contracts.
Challenges we ran into
Dynamically adding photos into the window in HTML. Using MetaMask to allow for transferring between accounts.
Accomplishments that we're proud of
Having a working solidity contract and communicating with IPFS.
What we learned
There is little documentation for blockchain tools, solidity and pretty much everything else we used.
What's next for Stock Block
To make it fully functional. Take it off the testnet, and onto the real Ethereum blockchain
