Looking for Beta Testers for a Probably Fair Gambling Prototype on Lightning
151 sats \ 10 comments \ @JordanPoulton 17 Sep 2022 bitcoin
Hey Stackers - myself and a friend are fascinated by the potential of Bitcoin. We're currently building/learning how to build products and services on the Lightning Network (BTC), and we've just launched our first prototype product - a really simple, provably fair, no signup, instant payment, 50:50 'coin toss' app. 🙂
Here's a link if anyone is interested: https://roll.satsumo.xyz/
We'd really like some feedback from others in the Bitcoin community so please take a look, get yourself a Lightning enabled wallet if you don't have one already, and start betting with a few Satoshi.
As always feedback very welcome :)

If you have suggestions for how we can better deliver 'provable' fairness, I'm listening ☺️

We take 2% from any winning bet to cover the costs of running the service. This is called a rake.

We're open to suggestions for other ways to cover our costs (eg server space &infrastructure services) and to mitigate risk, if you have them 🤙🏼

if you’re betting ‘2/1’ odds, we basically take a random number from 1 to 100, and if it’s above 50, the house loses, which is another way of saying ‘you win’. If you’re betting ‘4/1’ odds, we take a random number from 1 to 100 again, and if it’s above 75, the house loses, and you win. If the random number is below 75, the house wins, and you lose. If you chose odds of 5/1, your random number needs to be above 80 etc.
You guys might need this: https://en.wikipedia.org/wiki/Odds especially the part about odds = p / (1 - p)

That's not provably fair at all. The random number that you've used is not a proof of anything because you could repeatedly generate random numbers until you get one that results in a win for the house.
