Title: Cryptodraw.eu | Decentralized Ethereum Lottery Pools
Post by: berrybats on May 11, 2018, 04:30:20 PM
Hi,

Last week we released the public version of https://cryptodraw.eu (https://cryptodraw.eu).

Users are able to buy tickets and when the ticketsize is met (or a specific timestamp), everyone is able to draw the lottery and one user gets all.

As of today there are 2 pools available, in the future alot more!

You can join or draw the different pools with MetaMask or any other service. Details are within every pool. Please do not use exchange addresses.

Also don't forget to join the https://t.me/joinchat/AqL2gkSU33guRGzXh3YDYw (https://t.me/joinchat/AqL2gkSU33guRGzXh3YDYw) channel to meet up with other gamblers! :)

A random numer is generated as follows:
1: API call to Wolfram Alpha, requesting a random 20 words string.
2: This string is hashed to keccak256 and transformed to only integers.
3: A modulo operation is set on this huge integer with the size of the playerlist.
4: Funds minus pool fee is sent to the winner. <3

Nicely done! I like it Transparent & Decentralized smart-contract.
Will give it a try, good luck with your project.

p.s. what will happen if the pool wont get filled? refund or draw with current amount participating users?

Thanks! When the pools do not get filled with enough users, everyone is able to draw it when the time exceeds the timestamp stated. The lottery will then pick a random number between the joined participants.
