Resource-Intensive:
PoW requires participants (miners) to expend computational resources to solve mathematical puzzles, making it a resource-intensive process.
Block Reward:
Miners who successfully solve the puzzle are rewarded with the right to add the next block to the blockchain, along with a block reward in the form of cryptocurrency.
Decentralization:
PoW promotes decentralization by distributing the validation process among a network of miners, preventing a single entity from gaining control over the network.
