I've been working on a new electronic cash system that's fully

peer-to-peer, with no trusted third party.

The paper is available at:

http://www.bitcoin.org/bitcoin.pdf

The main properties:

Double-spending is prevented with a peer-to-peer network.

No mint or other trusted parties.

Participants can be anonymous.

New coins are made from Hashcash style proof-of-work.

The proof-of-work for new coin generation also powers the

network to prevent double-spending.
