Proof-of-Work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions on the distributed ledger or blockchain.
<h3>What is Proof-of-Work in Cryptocurrency?</h3>
- A type of cryptographic demonstration known as proof-of-work involves one party (the prover) demonstrating to another (the verifiers) that a certain amount of computational effort has been put forth.
- Consequently, this spending may be easily verified by verifiers with little work on their behalf.
- The goal of proof-of-work algorithms is not to demonstrate that a task was completed or that a computational challenge was "solved," but rather to prevent data modification by imposing onerous energy and hardware control constraints.
- Environmentalists have criticized proof-of-work systems for using too much energy.
- Later, Bitcoin popularized proof of work as the basis for agreement in a permissionless, decentralized network where miners compete to add blocks and create new money.
