Daemon shouldn't generate and store private-pubic key pairs. This could come from a standard platform, like gpg
Have you looked into OpenTransactions? Regardless, I've often wondered why Satoshi reinvented so many wheels. Why not use GPG for cryptography, key exchange and trust models and not store the block chain in a git repository.
OpenTransactions? - yes, I looked into, but only after your post
Thank you for this hint. It is really interesting. If it exists widely used and accepted standards (gpg, bittorrent or similar, ... and maybe OpenTransaction) for a job - I will prefer it. Git repository for a chain? With some different branch, and then with merge? This seems to be interesting too.
