How Bitcoin Uses the Proof of Work Consensus Mechanism
bitcoin’s proof of work relies on miners solving complex cryptographic puzzles to validate blocks, secure the network, and make attacks costly through high energy and hardware demands.

bitcoin’s proof of work relies on miners solving complex cryptographic puzzles to validate blocks, secure the network, and make attacks costly through high energy and hardware demands.
bitcoin’s network automatically adjusts mining difficulty about every two weeks, based on recent block times, to stabilize the average interval between blocks at roughly ten minutes.
bitcoin halving is a programmed event that cuts mining rewards in half, limiting supply growth. It helps control inflation, impacts miner profitability, and can influence market dynamics.
This article explains the bitcoin block reward: how miners earn newly created BTC plus fees, how halvings reduce rewards over time, and why this mechanism secures supply and incentivizes mining.
Proof of Work requires miners to solve difficult cryptographic puzzles to add blocks and confirm transactions. bitcoin uses PoW so altering history becomes computationally impractical.
