(For answers to all of your questions, please read the FAQ.) For a broad overview, the software features:

— UNTRACEABLE DIGITAL CASH: Fully implemented! Cash withdrawals of any asset type, using Lucre. (Ben Laurie’s implementation of Wagner’s variant on Chaumian blinding.) Once cash is withdrawn, the server has no way of tracking it or linking it back to its next deposit.

REPEAT: Digital Bearer Certificates—with denominations, mints, expiring tokens, spent token database, the works—fully-operational and ready to integrate with your mixnets, your digital gold currency (or silver), your anonymous network nodes, your bittorrent clients, your remailers, your secure voip apps, your nym servers, your snazzy, new, file-sharing client, and your censorship-resistant, distributed data store. This is what you have been waiting for! Real, open-source, digital cash.

Jct: The greatest feature of LETS is that it is an open information database. Everyone can see everyone else’s account so there’s no way to steal because there’s no way to stow the stolen credits. There’s no need for encryption.
