Interesting!

As far as I can see, you are actually discouraging people to place bets as results will only be known (on average), every ten minutes.

I also see that you have a "block time" on the top right corner which is (I guess), your local time (GMT+8). I guess you are based (or from) China. Possible to adjust the time to something appropriate to the player, or at least (I think blockchain uses GMT)

Thanks for advises!
Yeah,it's may be more proper  for those faster coin like LTC or YAC.

Ahahah no.

If I was a malicious miner and I found a block, and I would make 25 BTC + fees from publishing the block (so around 28 BTC?), I could bet on your site for a few hundred BTC and make it +EV.

Miner can choose to not broadcast mined blocks if the block hash would make them lose. This doesn't guarantee that they will win (as another miner will probably find and broadcast the next block hash), but it shifts the odds enough in their favor so that they can make a profit.

In my opinion,abandon a block is just the same as didn't participated in mining a block,so odds won't change.

That's nice, but it is not a matter of opinion.

If I bet heads on a coin toss, then toss a coin, see that I've got tails and so throw the coin away and let you make the 2nd toss, don't you think I have a better chance of winning?

HH = win
HT = win
TH = win
TT = lose

I have a 75% chance of winning if I'm allowed to abandon the first result when I don't like it.

I like the idea of letting your players bankroll the site.  You're a genius!  :)

To be fair to the bloke. Your site is heavily based off other games too :P It's nothing new around here to see people copying each other.

@OP. I think you should probably get someone whose native language is English to proof read your text. It's very off putting to say the least :P.

Best of luck with the site!

But the blockhash is the result of proof-of-work,you don't have a chance to make the 2nd toss.

Yes you do, you do not have to broadcast your block hash. Let me work this out step by step to you:

You bet 100 btc on hashdice.com. 50% chances.

You find a block. You calculate the block hashes...

(a) You win the hashdice bet! You publish your block. 50%
(b) You lose the hashdice bet! :( You don't publish your block. Now two things can happen:
(b1) Someone else finds a block and you win the hashdice bet! 25%
(b2) Someone else finds a block and you lose the hashdice bet! 25%

EV = 2 * 0.5 + 2 * 0.25 = 1.5

The miner can choose to NOT broadcast the block IF it won't win the bet. If it WOULD win the bet, the miner would publish. It lets them roll the dice twice - the first roll is choosing to publish it or not, the second roll is another miner mining.

I'll raise a bounty for transalations to other languages,includes english.
By the way ,are you two guys's  avatars related?it's funny.

Or don't bet money until you found the block, then include the transaction and broadcast it yes/no.
