Description
Experience Level: Expert
Create a single-page interface for notarising documents on Ethereum testnet. Fyi, an existing example is www.docstamp.it, but we want something with a nicer design and 4 tabs:
Notarise a file - drag& drop file, compute hash. Check if already registered, if not offer to notarise.
Notarise text - paste text into a textbox, compute hash. Check if already registered, if not offer to notarise.
Register a hash - paste number into fixed-size textbox. Check if already registered, if not offer to notarise.
Statistics - initially just info about the number mainly info about
This will involve a bit of graphic design and css, as well as a some Javascript. I already have a very basic web page for registering a hash on the blockchain, and for checking if a hash is already on the blockchain. In other words, the javascript code to communicate with the blockchain already exists and can be reused (although it may need cleanup). What is missing is a function to compute a sha2-256 hash, that will need to be added, there are existing libraries for that.
You will need to install Metamask (https://metamask.io) to do this job, and get some test ethers (free from http://faucet.ropsten.be:3001). You do NOT need to know anything about blockchain or blockchain programming.
