GOLD RUSH
Provably Fair

Provably Fair

Nobody picks the winner here. Not even us.

Before a draw runs, we point at a Solana block that has not happened yet and publish its number. When the blockchain gets there, that block turns up carrying a long random string, and that string is what picks the winner. There is no way to know it early, so there is no way to fix it. Afterwards you can redo the whole thing yourself, in this browser, in about a second.

Step 1

We call the block

A draw opens and we publish the number of a Solana block a little way into the future. That block has not been made yet. Nothing is inside it yet, so nobody knows what it will say, us included.

Step 2

The block decides

Solana makes a new block a few times a second. When it reaches ours, that block arrives with a long random string attached. The string goes through a fixed bit of maths that lands on one holder. The more tokens you hold, the more of the possible answers are yours.

Step 3

You check our work

We publish the block, the string, and the exact list of holders we used. Hit Verify on any draw below. Your browser redoes the maths from scratch and tells you whether it lands where we said it did.
