UPDATE :

DESIGN : I have changed the design, i hope it looks better than the first one, gimme some feedback !

PROVABILITY : The 1/10 is now 100 % provable and fair. Here is how it goes  : As soon as the 10th ticket is sold, the system gets the Transaction ID of that last ticket bought, and use the last integer of the TXID to pick the Ticket Number. It is displayed on the 1/10 page so everyone can verify it. Again, some feedback would be appreciated.

CONTENT : I have added the "Stats" page. The presentation is dull and plain, it is still a work in progress. As soon as i am fixed on what exactly i want to be in the page, i'll design it properly. Here again, if you think something is needed in that page, feel free to say it.

I am going to leave it like that for a little bit, see if i can get people to try it. But after multiple test, all systems seem to be working as intended. Good luck to those who try !
Yes provably fair but its a bad idea. When making your own transactions, you can see the txid before it is broadcasted, and you can cancel if you want, so basically you could try 10 times and then broadcast it when you get your right number.

I see... Alright i am going to change that and will base the draw on the next block hash instead.
I think this is a bad idea as well, because its still predictable I think, maybe calculate it from the block after the next one, hashed with the address of the final payer, and take the hex value of the first couple digits of the hash.
