[ANN][CHA] Chancecoin, SuperNET core coin for betting in a decentralized casino

Step 3: sports betting via decentralised system that determines the odds

Everyone is talking about betting sport but this cannot be decentralized.

why not? it's basically an exchange with prices that determine the odds. house edge could be easily implemented, hardcoding of the results shouldn't be extremely difficult. or am i missing something?

from where do you get 100% reliable and 100% true results without any trust issues.

How does the software post the bets? How could this ever be automated? Take bets from a centralised site? Can be manipulated.

I am 99% sure that sportsbetting can't be added..

Casino games on the other hand. Easy

[bhall6334]

Sportsbetting should be your #1 priority. It's a massive market where the standard juice is 5%. Make an easy to use betting platform with  smaller juice and there would be no reason for people to use traditional sites.

i'd like to hear one of the developers comment on this. the results would obviously be a problem, though a very similar one to the randomness problem that was solved via the ny lottery drawings. the community would agree on a source for the results and that would be kept until it goes down.
the rest in my view (posting the bets) could be achieved just like a decentralised exchange works.

it already exists using the counterparty protocol - countersports pre announced on bitcointalk - expect what happens when it is launched.

twin is basically right - also the configuration of cha protcol is concentrated on games against the house - counterparty is for peer to peer (gambling)

No,TwinWinNerD is not CHA dev.

Add Sports gambling first please. It's one of the most attractive betting market.

[Matt Y]

It would be nice to see a bit of a division between what Counterparty and Chancecoin do instead of competing for the same markets. I say this as someone who is going into a sports related business on the Counterparty protocol.

If you think sportsbetting can be added easily you are delusional.

There are so many probelms that come to mind. How are refunds ect handeled? How are bets handeled that get canceled because the house calculated the odds wrong?

the odds would be set by a market, as i said just like the decentralised exchange works. betting is like trading a digital option or maybe a cfd.
i also see a lot of problems of different sizes, though nothing that's really making this impossible. no refunds obviously, does bitcoin allow for refunds if you got robbed?

again, i haven't had time to actually think through every aspect, so i'd be happy if someone proved me wrong, though nobody has so far.

Please, this is pointless. Obviously you either need a market or an individual who sets the odds. And yes there is gonna be a market as soon as 2 people make bets. The more people bet, the more "accurate" the odds are going to be. One could start with an auction type of system in order to avoid putting people at an advantage/disadvantage who bet early.

No there is not. You are thinking of a place where 2 people can bet AGAINSt each other. While is certainly possible to implement, (Rather easy, and already done on XCP) it has NOTHING to do with Chancecoin.

Alright, per definition can you not have a betting system without either p2p interaction or central authority. The question here is how far should CHA go, if the limit is p2p interaction then obviously you can't go far beyond dice games or roulette. The interesting part of the gambling world is in interaction with other players, though. So I'd say why not introduce interaction (at a later point probably, first things first)

There is already a coin/system that does that. And basically all people that invested in this coin don't want to trust somebody. The whole appeal of this coin is that noone can cheat here.

Lets look at it another way. Why is BTC so awesome? Nobody can manipulate the total number of coins. Same goes for CHA.

Now we introduce your sportsbet manager that sets the "fair" odds. What happens if he goes rouge or makes a big mistake? Like he creates 500000 new coins by accident (fat finger)?
This isn't all to unrealistic... Mistakes happen all the time.

I'd rather see a fork with those features, than see that implemented into CHA. CHA should focus on all the casino games that are out there. Slots, roulette, blackjack, dice, and many more...

A market is as fair as it gets, I'm not in favour of a sportsbet manager. I mean I think we're at a dead end here, I think you're excluding a lot of gambling by excluding interactions with other players (such as one of the most popular casino games, namely poker), but if you don't think so I can't change that and I see your point.

Don't get me wrong, we can add a p2p layer ontop of CHA where players can bet against EACH OTHER. Just not against the house, thats all Im saying!

Cool would be a system like this: People place their bets, if more than say 50 bets for one event are placed, the odds could be determined (let's say 20:30, so 2:3) so then the whole thing is resolved via chancecoins usual system (coins are created for the winners, destroyed for the losers)
That would bring P2P and CHA's original concept together. Only problem is abuse, one guy places all the 50 bets, and there are no "arbitrageurs" who bet against him. Don't know if that's killing the idea or if one could protect against this.

The system must be 100% un-exploitable and trust-less. So the only way would be a system like betfair or http://bitbet.us/. Those systems are pretty solid and can be implemented easily. CHA could introduce "rake", a fee that would be deducted from the payout of the winner. This way the other CHA holder would profit from the bets made on CHA network.

Step 3: sports betting via decentralised system that determines the odds

Everyone is talking about betting sport but this cannot be decentralized.

why not? it's basically an exchange with prices that determine the odds. house edge could be easily implemented, hardcoding of the results shouldn't be extremely difficult. or am i missing something?

from where do you get 100% reliable and 100% true results without any trust issues.

How does the software post the bets? How could this ever be automated? Take bets from a centralised site? Can be manipulated.

I am 99% sure that sportsbetting can't be added..

Casino games on the other hand. Easy

i'd like to hear one of the developers comment on this. the results would obviously be a problem, though a very similar one to the randomness problem that was solved via the ny lottery drawings. the community would agree on a source for the results and that would be kept until it goes down.
the rest in my view (posting the bets) could be achieved just like a decentralised exchange works.

Who sets the odds?

If you think sportsbetting can be added easily you are delusional.

There are so many probelms that come to mind. How are refunds ect handeled? How are bets handeled that get canceled because the house calculated the odds wrong?

i don't say it's easy, what i'm saying is it should be technically possible and achievable.

the odds would be set by a market, as i said just like the decentralised exchange works. betting is like trading a digital option or maybe a cfd.
i also see a lot of problems of different sizes, though nothing that's really making this impossible. no refunds obviously, does bitcoin allow for refunds if you got robbed?

It can be centralized somewhere. Why not? What is more important? Attractive and easily used and clear functions.

Decentralization+centralization is better sometimes.It will have advantages of both.
