A RANDOMNESS BEACON POWERED BY THE APEX ENGINE

THE MIDNIGHT BEACON IS A PUBLIC RANDOMNESS BEACON: ONE RANDOM NUMBER EVERY NIGHT. ONCE ALL APEX UNITS HAVE SEALED THEIR DAY, THEIR FINGERPRINTS ARE MIXED WITH A PUBLIC VALUE FROM DRAND THAT ONLY COMES OUT AFTER THE SEALS. NOBODY CAN STEER THE RESULT, NOT EVEN US, AND ANYONE CAN CHECK IT.

WITNESSED BY DRAND, FROM THE LEAGUE OF ENTROPY.

PROVE IT WAS MADE AFTER A NIGHT

Show that night's number in it. Nobody could know the number before that night, so whatever shows it can't be older. The first 8 characters are plenty: a guess would be right about once in four billion tries.
