Before the draw:
· the entries list is already fixed
· the future Bitcoin block is announced publicly
· the future hash does not exist yet
That is extremely important. Because nobody — including us — knows the future result.
Once the selected Bitcoin block appears:
· the hash becomes public
· it cannot be changed afterwards
· anybody can verify the calculation independently
We publish and everyone involved can check it:
· the selected Bitcoin block
· the full block hash
· total number of entries from the list
· the formula
· the resulting winning number
Everything is transparent and publicly verifiable. And it is outside of anyone's control.Here you can read in details how this system works -
