[LTS] Integrated One-Off Lottery and Dice about clams

[ClamProject]

To clarify: I am not suggesting a 'business' model that would benefit the development team. I would only be interested if the design was such that proceeds, if any, were directed towards the network itself. This could also give additional incentive to stake and secure the network; or be used to offset current inflation from the Proof-Of-Pearl Lottery.

Who doesn't like a good lottery!

I'm personally for the idea. It would be in there from the start had we had the time and inclination to do so imo.

After further consideration, the [LTS] solution appears to be starkly centralized. The question is: can the great minds at CLAMS figure out a fair, non-cheatable, way to remove the centralization?

figure out a fair, non-cheatable, way to remove the centralization

That's not as easy as it sounds.

The basic problem with decentralised gambling is that I don't see any way of keeping secrets in a decentralised manner.

If the result of the lottery is known in advance, the player can decide whether / how much / when / how to play based on what the result will be.

If the result is decided after play in some decentralised way (such as using the block hash 3 blocks after he buys his ticket), the player can potentially influence that result (by attempting to mine that block and so determine its hash) such that he has a better chance of winning. We can make it so that the sum of the next 20 block hashes is used - but then only the 20th of those really matters, and we have no extra security.

I would love to be convinced that a good decentralised solution does exist however! :)

I will be frank, I do not understand the stakeModifier in it's entirety.
That said, is it not specifically designed to be difficult to pre-calculate?

[dooglus]

It's difficult to predict what it is going to be, but suppose I already placed a bet, and I am staking. I see that I can stake a block because my hash meets the required difficulty. At that point I can check what submitting my new block will cause the stake modifier to change to, and see if that causes me to win or lose the bet.

If it causes me to lose the bet, I simply don't submit my new block, and hope that the next block is better for me.

It's not a guaranteed win, but it may be enough to tip the odds in my favour enough to make the game profitable for me, long term.

So, the experiment of blockchain staking based lottery has officially failed and has been removed.

Research into a better option has been ongoing, I'lm going to close this and open a new issue so we can dissus it
