The initial modern application was way back in 1996 under the Hashcash . Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on averagebefore a valid proof of work is generated. It is used to ensure that all transactions occurring on the blockchain are genuine, as well. Proof of Work was successfully applied by Satoshi Nakamoto to Bitcoin in 2009. A big part of mining involves consensus. What is Proof of Work / Proof of Stake Watch later Watch on In practice, this means that if someone has solved the problem correctly, he has proven that the principle works.

Since then, PoW has been one of the most popular consensus mechanisms in the cryptocurrency ecosystem. Followed by Ethereum, Litecoin and there are many other coins. Verifiers can subsequently confirm this expenditure with minimal effort on their part. This keeps the integrity of the transaction intact. In recent years people started working on a different technique called Proof-of-Stake. The market cap of the Proof-of-Work sector is $ 1.69T, representing 63.10% of the total cryptocurrency market cap. Put simply, proof of work helps complete and secure cryptocurrency transactions.
