Building Blocks --> Random Event Protocol

The Random Transaction fulfills one of the most common features in games – generation of random events. Previously called the Shoe, for its similarity to a card deck shoe, the Random Transaction can build the equivalent of cards and dice for casual games and advanced computer games, alike.

The Random Transaction can be thought of as a more advanced version of the Simultaneous protocol with one key difference – the “dealer”. This protocol is a cryptographic  "collaborative shuffle" by all game participants, something you cannot do in real life!  As long as there is one honest participant, any tampering of random events ("rigging of the game" can be detected.

When the game is done, and all the random events are generated, the dealer reveals all of the “shuffles” to everyone so they can verify that the random events that they saw match with those they should have received. This goes far being simple extraction of recorded logs, but is actually a cryptographically secure reconstruction of the game events that can be done by any game participant, even if disconnected from all other participants.

This technique is based on deterministic random number generators and hash functions, integrated in a new way as described in our international patents.

The mathematics and details of this protocol are described in our Technology Section --> Cryptography (view the Cryptography for Secure Game Elements of Chance).

 

The Random Transaction supports both sampling with replacement (like dice) and sampling without replacement (like cards or bingo).  The Random Transaction also supports the privacy function, described in the Multi-step Transaction. Note, the Random Transaction can be replaced by the Simultaneous Transaction when there is no secrecy in results and the extra overhead of the transaction can be supported.
