Proof of Work (PoW)
Proof of Work is a consensus mechanism where miners compete to solve complex mathematical puzzles. The winner adds the next block and receives block rewards plus transaction fees.
Understanding the Concept
Bitcoin runs on PoW. It's the original and most battle-tested consensus mechanism. Security comes from the electricity and hardware costs required to attack the network—you'd need to outspend all existing miners. Critics call it wasteful; supporters call it necessary for true decentralization and security. Mining is an industry—understanding PoW helps you understand Bitcoin's value proposition and predict miner behavior (like selling pressure after halvings). PoW chains (Bitcoin, Litecoin, Dogecoin) have different security properties than PoS chains.
Real-World Example
Bitcoin miners run specialized ASIC hardware 24/7. They compete to find a valid block hash, spending thousands in electricity. The winner receives 6.25 BTC (currently) plus all transaction fees in the block.
