Block Reward
The new coins plus fees a miner or validator earns for adding a block — currently 3.125 BTC per Bitcoin block.
The block reward is what a miner or validator receives for successfully adding a block: newly created coins (the subsidy) plus the transactions’ fees. Bitcoin’s subsidy started at 50 BTC in 2009 and halves every 210,000 blocks — it’s 3.125 BTC today and drops to 1.5625 BTC at the next halving around April 2028.
The reward is both the network’s security budget and its monetary policy: it pays for the energy and capital protecting the chain while controlling issuance. As subsidies shrink toward zero (around the year 2140 for Bitcoin), transaction fees are designed to take over funding security — one of the ecosystem’s genuinely open long-term questions.
