What is POW (Proof Of Work)? and How It Works in Bitcoin. If you’re following crypto community for a while, you heard about Proof Of Work concept used by cryptocurrencies to mine coins. To understand the mining process in cryptocurrencies you have to understand POW.

Bitcoin miners find a random number (called a "Nonce") that when inserted into the current block makes the hash be below the current target. They then send that current block around the network and everyone checks their work (the proof-of-work) by hashing the block and checking if the result is below the current target. In mining pools, miners.

The conventional wisdom could be challenged because miners mainly operate on cash, meaning they need to liquidate their.

the proof of work is a protection and a solution for the Byzantine general problem without it miners will cheat easily without losing anything so they set this system POW to enforce the participants to loose money if they cheat (you loose the invested money in the POW process (electricity consumption and useless invested budget in the hardware)) instead you have an incentive if you don’t cheat.
