how much have been the 100% for the winner?
congrats to the winner
congrats to the winner
It was actually a combination of fewer ball matches (not the 6-match jackpot) that resulted in total payouts for draw #31536 being more that total spent on tickets for the draw (ie. over 100% payout to players)
Because the 8Bet.io bitcoin lottery games pay out much, much higher than regular lotteries, it is not uncommon for a number of tickets matching fewer than 6 balls in a draw to make the entire draw exceed 100% payout (you don't have to have a jackpot winner to have over 100% payout in a draw).
For example, Revolution Lotto pays:
- 3x for matching just 2 balls!! (you will find no other lottery with this crazy payout!)
- 10x for matching 3 balls
As the product has just launched, the jackpots are still low at just over 10 BCH (but growing) - however all the payouts for matching less than 6 balls are very high, so this makes these games very interesting while waiting for the big hit to come

confused a bit. according to the blog you switched to Bitcoin Cash is that correct?
Yes, we switched to Bitcoin Cash as the native playing currency for the platform - but players can still deposit in BTC, BCH, and LTC (with more coming). We had to make this change because of the Core scalability issues at the end of last year - high fees (fees many times higher than our ticket costs) and long confirmation times were a non-starter for a lottery product. We also need fast and (almost) fee-less internal movement of funds in order to achieve our goal of 100% return to players.
So BCH works as the native/internal/playing currency and the jackpot is denoted in BCH - but players have choices on deposit and withdrawal cryptos.
and you earn nothing?
Yes, the model is 100% return to players. There is no house edge, it is a zero margin lottery.
The platform is powered by players - contributors do the development, management and operations. "Marketing" is by word of mouth, players spreading the word, posting links etc. Players who aren't contributing time or awareness can opt to donate funds (default of 5% of only winning tickets), which get used for operational costs (hosting etc.) or for bounties for paid feature development.
pevpot closed down and many more. why do you think you will succeed with your lottery?
We've had a quick look at the pevpot model based on another comment on here, and 8Bet is quite different. The house-less model with a player cooperative running the platform hasn't been done before (to our knowledge) so we are treading new ground.
Ultimately the opportunity to gamble on a 100% return model with a genuine chance of winning and not being fleeced in the long run resonated with a lot of fellow gamblers (this blog post explains why: https://8bet.io/blog/gambling-today-is-flawed/) , so we are already a group of interested customers ourselves. In the long run the market will dictate if 8Bet lives or dies - if enough players find value in the 8Bet model they will "vote" with their bankrolls, instead of spending it at the usual house-edged establishments.
any other games on the way?
Yes, we're working on ways to disrupt other types of gambling too - working on models for 100% return casino games etc.
But right now, the focus is on lottery (2 games at launch) and we'll take it from there.
good luck
Thank you! If you'd like an invite to the private beta currently underway, please message me.

Thank you! Both excellent points!
Agreed that making the ticket list public prior to the draw is an important improvement to the provably fair model - so yes, we'll take this on board and add this feature to an upcoming release. As a quick first thought on this, we'd also ensure that the ticket numbers chosen on each ticket remained private (hash with salt maybe) so player privacy was maintained (ensuring an attacker couldn't link tickets together for players choosing the same lucky numbers in each draw, or some other form of anti-privacy analysis) - but it would still be indisputably provable that the numbers on the winning ticket were generated and bought prior to the draw.
Regarding miner collusion - yes, this was a concern of ours too. In fact, we had first implemented a complicated results generation model that had a list of random indexes to transactions within the next block, and generated the RNG seed from the least significant bits of the transactions at these indexes. However, we discarded this as being overly complicated to explain or for the average player to have to step through to prove. We opted for the block hash in favour of usability and ease of understanding - but your point on miner collusion possibility still needs addressing.
It would actually be interesting to calculate just how much of the global hashrate you'd have to control in order to make this sort of collusion viable, and how this would relate to the size of the jackpot - where the tipping point would be to make discarding a block feasible. We'll take this one to the whiteboard and mull it over some - as you point out, in the early stages with jackpots smaller than the block reward this sort of collusion is idiotic so less of a concern. However with time we expect jackpots to significantly exceed block rewards, so we will aim to have a solid solution for this well before then. Watch this space!
Thanks again for the great feedback!

Don't worry about miners trying to cheat so they can win some lottery.
Yes it is possible however I don't think the pools would get together and try to cheat you guys.
Even if 1 pool tries to cheat, it highly unlikely that they would mine the specific block of the lottery.

Original post from peer review below (since only one thread per site is allowed):
8Bet.io is a player-powered crypto gambling platform about to launch a 100% return cooperative lottery. We've published a blog post describing the Provably Fair model that uses the Bitcoin blockchain for the random number generator, see here: https://8bet.io/blog/how-it-all-works/
Extract below, for convenience. We'd welcome peer reviews of this model, with any constructive criticism of this method, thoughts on possible exploits, concerns etc. Thanks!
The 8Bet Lottery results are generated as follows:
1. At the start of the game (before any tickets are sold) a server seed is randomly generated by the server.
2. This server seed is then hashed using SHA256 and the seed hash is then published on the game for all to see. Because this hash is public from the start of the game, the original random server seed can not be modified in any way.
3. Players then buy tickets for the game until the time of the draw.
4. At the time of the draw, ticket buys are closed and the game waits for the next block to be mined on the Bitcoin blockchain. When this happens, the game takes the block hash from this next block.
5. The server seed and the block hash are then joined together and this concatenated server seed + block hash is hashed using SHA256. This hash is then used as the RNG seed for the random number generator.
6. The lottery results (6 lottery numbers) are then randomly generated by the well-known Mersenne Twister random number generator.

There has been provably fair lotteries before and one of the few ways to do it properly is indeed using a future blockhash. One example would be PevPot (doesn't run anymore though - but cached provably fair page and open-source code.)
There are other ways to do that though, but publicizing the ticket list (and making sure people have it before the result) is a crucial part of it.
There is still a chance that you and the miner are colluding, withholding a block just because you don't like the winning result (and have a second chance with next block.) This probably only makes sense if the potential loss is bigger than the miner reward. So as long as the total prize is less than 12.5 BTC, you should be fine. But for this reason, PevPot added a slow calculation that took hours before we could get the result.
3. Players then buy tickets for the game until the time of the draw.
Make sure that all the tickets are public and known to everyone. Otherwise you can just claim to have the winning ticket yourself. PevPot did this by using 1 public address, use TXs confirmed between blocks x and y, sort them by TX ID and make every satoshi worth 1 ticket. This way, everyone with access to the bitcoin blockchain can make the list of tickets themselves - without even visiting the site.There are other ways to do that though, but publicizing the ticket list (and making sure people have it before the result) is a crucial part of it.
6. The lottery results (6 lottery numbers) are then randomly generated by the well-known Mersenne Twister random number generator.
You can just assign a number for each ticket entry, generate a number based on this seed (serverseed + blockhash) and compare the two. PevPot used some modulo way. But MT (with own seed input) could work too.There is still a chance that you and the miner are colluding, withholding a block just because you don't like the winning result (and have a second chance with next block.)
