Finally: Accountable CF Predictions
By kostia244, history, 9 months ago, In English

We have these prediction threads all the time, but we never collect the data or hold people accountable. I have a project that might help with this.

I created a reputation token that you can use to bet on WF winner and runner-up. You bet on universities and tokens from losers get distributed to winners (so payouts are dynamic based on how many people got it right).

Even tho it's on a blockchain it is free and not about money—it's about bragging rights.

How do you get tokens?

Well if I just gave them to everyone it would be pointless, so I use CF OAuth—you get 100*max_rating tokens.

Why blockchain?

This token is an ERC20 on Ethereum testnet. Mostly because it made development more fun. But here are some benefits for you:

Everything is completely free—I cover gas fees so you just need a CF. You can use it for bets with your friends, if you trust them to transfer it upon losing. You could build some other prediction system using them.

Getting started is dead simple:

  1. Get MetaMask (browser extension or mobile app)
  2. Go to the site and connect wallet
  3. Login with CF to claim your tokens
  4. Place gas-free bets

Works on mobile with the MetaMask app too.

Important: This is NOT a financial product. Tokens have zero real value. This is purely for fun and competition.

The contracts aren't verified yet, I'll do this when I have some time.

maybe formulas like exp(max_rating / 500) will be better?

I think the formula $$$300000 \cdot [R \ge 2400]$$$ is much better

UPD: I improved gas fee calculation, some transactions used to fail because of this. Now it should be better!

There was some issue with tx submission, now it works.

Dumb question: how do I place a bet? I see my balance in the top right, and the pools below, but no obvious interface for actually placing the bet.

    Waiting for oracle to report event to the blockchain. — I'm guessing this used to be a betting button, and bets closed some time before the official contest start?

      The pool was closed 3 hours before conteset. I was afriad that the contest would start too early. In hindsight, 1h before would be more reasonable.

Hi guys, here's an update. The pools have been resolved!

Here you can see real and predicted top5.

I invoked withdrawal for winners. (Except for one guy, who did it himself xd).

I also gave 10k tokens to those who lost everything.

If the hackercup happens, I'll host predictions for it too. It should be even more fun.
