Mersenne Cards has reached "barely usable" status and allows two mutual untrusting parties to play card games without a trusted third party or any intermediate server.

Current features are enough for "Mental Poker":

  • WebRTC rendezvous
  • Shuffle the deck
  • Deal cards face-up or face-down
  • Provably reveal the contents of cards
  • Discard from their hands without revealing the cards
  • Chat

@th Interesting! I can't find this thing online though. Can you point me at a repo, or a writeup that explains the underlying principles?

@minoru No dealer, no servers, no cheating. The underlying encryption is based on the SRA algorithm, with some extensions to detect cheating immediatley.
