Until January 15th, 2022, you (yes, YOU) can (secretly) put your Ethereum in either the letter **A** or **B**.

Why should you give your ETH to a letter, you ask? Because, if your side is the **least popular** (has the least ETH), you win the other side’s ETH.

Choose a letter [here](https://www.avsb.xyz/).

How it works
------------

There are 3 phases. We follow a Commit-Reveal scheme (all dates 2022).

**1st: Hidden Voting**

*   Until January 15th, players put ETH behind A or B (in increments of 0.01Ξ)
    
*   Choices are hidden (only cryptographic commitments posted)
    

**2nd: The Reveal**

*   After January 15th, players have 5 days to reveal what side they chose
    
*   Reveal verified by checking cryptographic commitment
    
*   Side with **less** ETH revealed decreed winner
    

**3rd: Payout**

*   After January 20th, players of the winning side can claim their prize
    
*   Only players that revealed in Phase 2 can claim
    
*   Prize is proportional to the ETH they put in
    
*   95% of funds are paid out to winners, 5% fee taken by app
    

And of course, all of the above happens trustlessly. **For the only definitive and meaningful information on rules, read the smart contract on Etherscan.**

Why does this exist
-------------------

TLDR; this exists to pit people against each other and see what we can learn about each other in the process.

There are a number of miscellaneous, somewhat unrelated reasons we think this should exist in the big bad world.

*   we were bored
    
*   will people play both sides (lower variance, possibly negative EV due to fees) or will only people with a strong conviction play?
    
    *   keep in mind, one wallet address = one vote
        
*   what sort of reasoning will people use to choose their voting side and amount?
    
*   how will people choose when to reveal during the reveal phase?
    
*   will people vote multiple times? if so, is it always best to reveal all votes?
    
*   crypto should be used to scalably test game theoretic questions
    
*   how rationally do crypto users behave?
    
*   are people more concerned with profit, or community and narrative?
    

Besides, maybe A and B represent something else. Something larger. Maybe A is mAinstream and B is suBversive. Maybe mountAins are better than Beaches. Amazon vs Blockchain. cAr vs Bike. Or maybe A is just A, and B is just B.

Implementation Quirks
---------------------

As with smart contract applications, there are some minor implementation details and edge cases that players should be aware of.

*   technically, players can reveal their vote anytime before January 20th (including before January 15th)
    
    *   however, revealing early is shooting yourself in the foot ... unless you do it on purpose for a reason 🤔
        
*   a 5% fee is collected at the end, during the first payout
    
*   if only one side reveals no ETH, then the other side wins
    
*   **if there is an equal amount of revealed ETH behind both sides, everybody wins and can claim their remaining share of the total**
    

With love,

some bored kids
