Proof of Work (PoW) is a consensus mechanism where miners use computing and compete to solve mathematical puzzles ... In Bitcoin’s case, this hash algorithm architecture is called SHA-256.

Proof of work is a consensus mechanism ... The system requires miners to compete with each other to be the first to solve arbitrary mathematical puzzles to prevent anybody from gaming the system.

Proof-of-work ... When you solve your puzzle, you receive transaction fees for adding the new block. Unlike Bitcoin’s consensus mechanism, there are no miners and no heavy computational ...
