The idea here is that it's a public, traceable generation of random numbers. So, if the two of us wanted to flip a coin to settle a disagreement, we could agree on some future value of this beacon (unknowable to us at the moment) to use as the source of entropy, then let one of us choose heads or tails, telling the other person what we chose. Then we wait until the agreed time, check the beacon, and boom, a fair coin toss, which we can be fairly certain wasn't manipulated by either of us. |
