What’s the deal with Crypto (PoW)er?
Proof-or-Work (PoW) better known in crypto as mining is simply a mechanism that allows a computer to accomplish useful work.
This mechanism is significant because it demonstrates that somebody invested real effort into finding a solution to the current block. Proof-of-work (PoW) also makes tampering with transactions impossible because you’d have to redo all of the work done by the proof-of-work for the block containing that transaction; this protects transactions from being changed by anybody who does not possess an enormous amount of computing power.
In crypto, transactions are broadcast to all users over the network who are required to validate these transactions by solving computational puzzles that are difficult to solve but easy to verify AKA mining.
Basically, the effort into making these puzzles time-consuming to solve while being easy to verify is what we now call proof of work (PoW).
