Many applications require trustworthy generation of public random numbers. It is shown how this can be achieved using a hash function
that is timed to be as slow as desired (sloth), while the correctness
of the resulting hash can be verified quickly. It is shown how sloth
can be used for uncontestable random number generation (unicorn),
and how unicorn can be used for a new trustworthy random elliptic
curves service (trx) and random-sample voting.
