Now you can also P2P gamble using smart contracts.



The oracle FOPUBEUPBC6YLIQDLKL6EW775BMV7YOH (which also monitors Bitcoin blockchain) posts pseudorandom numbers derived from Bitcoin block hash.  A new number is posted every time a new Bitcoin block is mined and gets one further confirmation.  The random numbers are posted under data feed name randomXXXXXX where XXXXXX is Bitcoin block number.

The numbers are between 1 and 100,000.  You can bet on a future random number being less than or greater than a specific value, for example, there is 25% chance that the number will be below 25,000 and 75% chance that it'll be above 25,000.

The above contract was between my Mac and my phone, it was created before block 460852.  This is the data feed that was posted by the oracle after this block was mined:

bitcoin_hash: 0000000000000000019dd457cf8e233701dab44ac855492d575a4366556213e0
bitcoin_height: 460852
bitcoin_merkle: GW9cQW5m0KLIi2suUlkzRP2yurg8jLEax3uHiun7kik=
random460852: 34789

34789 is more than 25000, the Mac won.

P.S.  And we didn't need to do a $2m ICO to organize this simple game.
