Existing colored coin clients: WebcoinX, ArmoryX, bitpaint.py.

We need to develop a new one which:

• will be flexible and versatile
• can work in stand-alone configuration, but also can be sped up with help of 'server'
• provide an API for other applications to connect to, or work as a library
• (relatively) high performance
• stable, safe, secure
• (relatively) low overhead (compared to Armory which requires gigabytes of RAM)

There are several possible software platforms we can use:

• modification of bitcoind
• a stand-alone wallet which will connect to bitcoind (preferrably C++ or Python)
• C++ library which can be used either by standalone client or integrated into existing one

If we are going to develop a stand-alone application, it would have following components (approximately):

1. [colored coin store](NGCCC colored coin store): keep information about colored transaction outputs
2. [transaction representation, parsing](NGCCC transactions)
3. [interactions with bitcoind](NGCCC bitcond access)
4. [coloring kernel](NGCCC coloring kernels)
5. [import/verification](NGCCC import) (when you download history from external source, we need to run verification and fill our colored coin store)
6. [high-level coloring logic](NGCCC coloring logic): maintain the state, get info about new transactions, etc.
7. [wallet](NGCCC wallet)
8. [API](NGCCC API)
9. [color definition management](NGCCC colordef management)
10. [GUI](NGCCC GUI)
11. [p2p trade](NGCCC p2ptrade)
