bitcoin’s protocol cuts block rewards in half every 210,000 blocks, roughly every four years, slowing new supply, reinforcing scarcity, and influencing miner incentives and market dynamics.
bitcoin’s four-year issuance halving reduces the block reward, slowing new coin supply. This programmed scarcity aims to limit inflation, influence miner incentives, and shape long-term 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.
bitcoin’s protocol caps supply at 21 million coins. New bitcoins are released through mining and halvings; about 19.3 million exist today, with the final units to be mined around 2140.
