1. A method for generating a cryptographic address, the method comprising:

  • concatenating a public key and a modifier;

    executing a first hash function on the concatenated public key and modifier to yield a result;

    concatenating a portion of the address that is not node-selectable and at least a portion of the yield of the first hash function to create a network address;

    determining a value for the modifier for use by the first hash function by executing a second hash function on the public key and an initial value for the modifier; and

    repeating the execution of the second hash function while changing the value of the modifier until the second hash function yields a target result.
