POW (Proof-of-Work) and POS (Proof-of-Stake) are two different consensus mechanisms used in blockchain technology to validate transactions and create new blocks. In a Proof-of-Work system, miners compete to solve complex mathematical problems using computational power to create new blocks and validate transactions. The first miner to solve the problem is rewarded with new coins and the transaction is added to the blockchain. This process requires a significant amount of energy consumption and...
