Random number generation and systems for their use are disclosed in which parts of some contributing values are committed to or hidden or uncontrollable before they are revealed or combined. Plural parties generally contribute to the process of developing the random values and in some exemplary systems incorporating the random generator concepts other parties perform and verify the operation of the system. In some preferred embodiments, commitments or physical locking are believed to impede various cheating and collusion strategies. In other exemplary embodiments values that are committed to by a system remain hidden while a user influences other values that are ultimately combined with committed values to determine the results. In some further exemplary embodiments users of ordinary skill are able to control their contributions and in other examples users are believed to be unable to deliberately choose their contribution. Overall systems include capabilities to allow efficient communication and audit while protecting against fraud and ensuring privacy.
