Dear all, I'm happy to announce the release of GNU Taler 0.0.0. GNU Taler is a free software electronic payment system providing anonymity for customers. Payments can in principle be made in any existing currency, or a bank can be launched to support new currencies. Merchants are not anonymous, and--due to income-transparency--the state can perform effective tax audits. This is a first alpha release of the four key components providing logic for running a bank, exchange, merchant and wallet. What works: * Exchange implements the full Taler protocol, but does not integrate with traditional banking systems (only with Taler's own "bank"). * Wallet can withdraw and spend coins, but does not yet handle refreshing, refunding, synchronizing, or export of cryptographic proofs. Some error handling may be insufficient. The wallet was only tested with Chrome/Chromium. * Merchant backend can generate contracts and handle payments, but does not yet offer full back-office support for tracking payments received. Frontend examples are available in Python and PHP. * The bank can manage accounts, allows the wallet to withdraw funds and can receive payments from the exchange. Key open issues include: * Wallet transactions are sometimes linkable because refresh is not implemented. * There is no auditor, and hence components do not properly support auditors either. As a result, a dishonest exchange could embezzle funds. * No integration with "real" banks, so only toy currencies are available for now. * Documentation, testing, error handling and usability still need to be improved. You can download GNU Taler from: * All GNU FTP mirrors ftp://ftpmirror.gnu.org/gnu/taler/ * Our Git repository is at https://www.git.taler.net/ Please report bugs to our bugtracker at https://gnunet.org/bugs/ Documentation can be found at http://www.taler.net/ Additional documentation about the APIs is at https://api.taler.net/ A demo is running at https://demo.taler.net/ Happy hacking!
