How Does a ‘Hash Rate Marketplace’ Function?

A hash rate marketplace, such as NiceHash, allows users who own mining hardware to sell their hashing power to buyers who wish to mine a specific cryptocurrency without owning the hardware. Buyers bid on the hash rate, and sellers fulfill the orders by directing their miners to the buyer's specified pool and coin.

This market makes hash rate a commodity and is the primary source for attackers to quickly acquire 51% power.
