AI Thread Summary
The discussion highlights the limitations of centralized online poker networks, such as high fees and trust issues, exemplified by PokerStars and Full Tilt Poker. A decentralized poker network using Bitcoin is proposed as a solution, offering benefits like no rake, reduced government oversight, and player control over the software. The challenge lies in securely managing the pot without relying on potentially colluding players, suggesting a system where each player nominates trusted escrow services to hold fractional amounts of the pot. The proposed method involves players blacklisting untrustworthy escrows based on majority consensus to ensure fairness. Overall, the conversation seeks innovative ideas for implementing a decentralized poker system while addressing potential vulnerabilities.

Hey,

When we play Poker online, we are using a centralised network. You deposit your cash online, sit down at a game and play. You place your trust in the site to be secure; no other players can see your hands and no money is being secretly stolen from you. Even big name sites have been known to cheat and smaller sites just shut down and steal your money.

There are two well known sites- PokerStars and Full Tilt Poker. By being secure, they charge you excessive amounts to use their service. The market is monopolised by them since small sites are untrustworthy. This year I played on PokerStars and made $3k profit and payed $4.5k in rake- so I had to win $7.5k in total and hand over more than half my winnings to PokerStars. Many players hate this.

A decentralised Poker network (using bitcoin). Here's the advantages:
+ Government heavily taxes Poker sites. Decentralised networks are outside the law.
+ No rake.
+ Don't need to place your trust in a company
+ Customise your client since you own the source!
+ No http://www.pokertableratings.com/ gathering statistics on your play against the rules of Poker

How could such a thing be implemented?

Mental poker is a scheme for neutrally verifying cards among players but is slow. Yet I imagine there's ways to speed it up by relying on trust/probabilistic methods.

The real problem is money put into the pot. For those unfamiliar with Poker I'll explain: People bet on the strength of hands, and put money in a pot. After so many betting rounds, both players show their hands. The strongest hand wins the money put in the middle. How can this be decentralised?

The best scheme I imagined was if the pot was stored by a third party. We want to protect against collaboration so using the other players not involved in the hand at the table is not possible (5 of the 6 players on the table could be collaborating together and just steal your money). Each player could nominate a few escrows each that hold fractional amounts of the money. Since people disconnect (bad internet .etc), the escrows would need to be dedicated services.

6 players sit down at a table. Each nominates 2 escrow services that hold the money (12 in total). Player A and B start betting and putting money in the pot. $200 goes into 12 escrows or $17 each. After they show the hand everyone agrees player A won. But one escrow refuses to award their share of the $7 to A... Everyone at the table blacklists that escrow to never trust them again and alerts everyone else in the network. If the majority of the players at the table >50% agree that an escrow is bad, then everyone blacklists them.

My scheme is full of holes though. Looking for ideas.

In an escrow:

1. A offers to sell laptop for 2000 coins, and escrows X coins as security.
2. B offers to buy and escrows X coins as security.
3. B pays 2000 coins to A.
4. If A refuses to send the laptop, both A and B have lost X coins. Therefore, A has an
* * incentive to send the laptop, and B can't use this system to put A out of business.
5. A sends the laptop to B.
6. If B refuses to acknowledge receipt of the laptop, both A and B have lost X coins.
* * Therefore, B has an incentive to acknowledge receipt of the laptop.

where X > 2000 (e.g X = 2500)

In Poker here, the transaction confirmation is when the hands are revealed and the escrow confirms the winner. I'm asking about a distributed escrow in essence.
 
I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
