Enabling Secure Web Payments with GNU Taler
summary
Claims a working digital-cash system using Chaum's blind signatures, a browser-based wallet extension and auditable exchanges that keep merchant income visible while customers remain unlinkable; demo withdraws demo-bank Kudos into the wallet and pays 0.1 Kudos to read an article. Protocol avoids blockchain proof‑of‑work overhead and cites ~$7 per Bitcoin transaction and 2–6 TPS vs Visa’s thousands. It requires online exchange connectivity, currently has near‑zero adoption, and international transfer syncing is not yet solved.
