What Hacker News says
5 sourcesHi thanks for seeing that! I should probably take that link down for now. I'm working on making the code readable. If you are interested in the underlying technology. I used a combination of Python, Flask, Colored Coins and pybitcointools libraries. Check these out here: http://coloredcoins.org/ https://github.com/vbuterin/pybitcointools If you have any more questions please feel free to ask! I'm open to ideas and working together.
In Show HN: ToshiTicket – Concert Tickets on the BlockchainYou can push directly to Eligius if you want anything up to k-of-20; http://github.com/vbuterin/pybitcointools lets you do that with the eligius_pushtx command.
In How Jason Bourne Stores His BitcoinNice. I'm the developer of http://github.com/vbuterin/pybitcointools , a Python implementation of most of the parts of the protocol that you do not handle. Perhaps we could work on making the two work together as a complete Bitcoin node?
In Show HN: A pure Python Bitcoin protocol implementationActually, the key-recovery process is quite useful. The reason is that instead of having your public key be the public key itself, you can use the hash of your public key (ie. Bitcoin address) instead. This cuts the required "public key" length in half for the same level of security. The verification protocol then becomes
def verify(msg,sig,addr): return pubkey_to_address(ecdsa_recover(msg,sig)) == addr
