THIS DEMO IS NO LONGER AVAILABLEThe current version is just a demo: it works on Bitcoin testnet and is not secure. But it isn't just a mock-up: it actually uses blockchain, traverses transaction graph to identify colors, etc.
Basically, to make a client which can be used on mainnet out of it we need to add some crypto checks and optimize the way it works with blockchain.
So, here's a link to client:
http://bitcoinx.github.io/webcoinx/Notes on usage:
1. Colored coins are made of Bitcoins, so you need to have some in your wallet before you can issue your own coins.
2. The way it works now, you have to select currency you want in the drop-down menu BEFORE you choose what to do with it (send, trade, receive).
3. If color was created after you loaded the client, you need to reload page (or use 'reload / sync' button) to see it in drop-down.
Also note that p2ptrade section is ugly and not well tested... But, probably, it works.
I'll pay 0.05 BTC per usability report, for the first 10 reports. To claim bounty you need to reply to this with following:1. How would you rate ease of use, 1 to 10 (10 is best)?
2. Which features did you try? Did they work?
3. Did you encounter any problems?
4. What things would you change and how?
5. Any comments you want to include which do not fit in categories above.
6. Your Bitcoin address.
I plan to redesign user interface, making separate tabs: receive/send/issue/trade. I want to measure the baseline now to see whether there are improvements.
Testing instructions: You need more than one wallet to test sending and trading.
You can create mulitple wallets if you open it in different browsers (e.g. in Chrome and in Firefox), or one in normal window and another in incognito window.
(Wallet is stored in local storage so it is persisted as long as you do not clear storage. Incognito mode destroys local storage after you close window, so wallet won't be persisted.)
