Systems, devices, and methods are provided for generating and transmitting a stream of random numbers such that the transmitted stream of random numbers is based at least in part on two or more streams of received random numbers. A randomness beacon can include a processor, a transmitter, and a memory with instructions thereon to cause the beacon to receive the two or more streams of received random numbers, generate a new stream of random numbers based at least in part on the received streams, and transmit the new stream via the transmitter to a public network. A system can include the randomness beacon and two or more random number generators that are generating the two or more random number streams received by the beacon.
