Because the payloads are tiny and require almost no coordination compared to many algorithms.
Machines take small work packets and crunch numbers, then pass back results in minutes. For many clusters, various steps of the algorithms require fast messaging for things like MPI.

TL;DR Bitcoin: no coordination during work
