This article is particularly interesting in light of the various lotteries and other gambling devices which are available on the Ethereum Blockchain. They approach a similar problem from a slightly different direction, not always successfully.

I love solve this problem, is such an interesting point were trust and cryptography comes in place. I even try to build a prototype my self for p2p poker. I don't have anymore the code to share. Anyway I will also recommend this video about it: https://www.youtube.com/watch?v=mthPiiCS24A

the video actually features the second author of the paper.

> Can two potentially dishonest players play a fair game of poker without using any cards - for example, over the phone?

> This paper provides the following answers:

> 1. No. (Rigorous mathematical proof supplied.)

> 2. Yes. (Correct and complete protocol given.)

What if I use a different key for each card?

I found the answer in the youtube comments:

> Dan McNeill: What if I use a different key for each card?

> MrBawn: In the physical version, you could absolutely identify each card by which of your keys unlocked your lock without unlocking your opponent's lock. In the crypto version, you can't tell which of your keys works on an encrypted card because your opponent's lock has turned it into gibberish. So an incorrect key would be indistinguishable from a correct key.

If you want to play mental poker with an arbitrary number of friends/enemies, I built a prototype with a really basic UI that extends the SRA81 protocol to support more than two players and that also removes the need to reveal the hands at the end of the game. https://secret.cards/
