Additional Information

What is ‘Provably Fair’?

And how do you trust a provably fair giveaway? The system records all user entries on Dragonchain for time stamped and immutable proof of pre-qualification in advance of the selection of a winner. For selection, the system uses future hashes of a predefined block height of Bitcoin and Ethereum. The combined hashes are used to select the winner based on an algorithm described below. It is not possible to know the hash of a block height of any one blockchain, thus making it impossible to profitably game the system.

btc = <BTC timestamp + 10 blocks>
eth = <ETH timestamp + 10 blocks>
<repeat for other active interchains>

selection_hash = hash(btc,eth,*)
selection = python -c
'print(int("<selection_hash>", 
16 % <number of entries>)'

See an example of provably fair system in action.

Entrants and non-entrants alike can watch for the block hashes, see who the winner is in real-time, and verify for themselves that the results are accurate and fair. Neither Dragonchain nor Open Source Money is needed to declare the winner.
