Miners tend to focus upon having as much computing power as possible since it gives the greatest chance of solving the hash and earning the right to create a block. The incentive is paid out in the native coin.
This is the mechanism that is utilized by Bitcoin.
Those who engage in mining are known as miners.
Bitcoin was introduced by Satoshi Nakamoto. This was a revolutionary moment in the development of private, electronic money. Bitcoin was the first decentralized electronic validation mechanism. Prior to this, all electronic ledgers were controlled by centralized entities.
The biggest breakthrough came from solving the double spend problem without the use of a centralized entity. This was the issue with some other earlier initiatives by the Cypherpunks such as Bit Gold. Created by Nick Szabo, this was similar to Bitcoin with one major flaw: Bit Gold required a centralized entity to solve the issue.
