Proof of Work (PoW)

Proof of Work (PoW) is a security mechanism used in blockchain networks where participants, called miners, solve complex mathematical puzzles to validate transactions and add new blocks to the chain. This process requires significant computational effort and energy, ensuring that malicious actors find it costly to manipulate the system. Once a miner solves the puzzle, they broadcast the solution, and other participants verify its correctness. This consensus method maintains the integrity and trustworthiness of the blockchain without needing a central authority. Essentially, PoW relies on computational work as proof that a legitimate effort was made to secure the network.
