When a miner or validator does the work of producing a valid block, the network compensates them. That payment usually has two parts: freshly created coins (the subsidy) and the transaction fees paid by everyone whose activity is included in the block. The subsidy is the mechanism that mints new supply, so the block reward is effectively a blockchain's payroll for the people keeping it secure.
On Bitcoin the subsidy is not fixed forever. It started at 50 BTC per block in 2009 and is cut in half roughly every four years in an event called the halving, stepping down to 25, then 12.5, then 6.25 and onward toward zero. This is how Bitcoin approaches its 21 million cap on a predictable schedule. Over the very long run, as the subsidy shrinks, transaction fees are expected to make up a growing share of what miners earn.
Block rewards matter beyond trivia: they shape a coin's inflation rate and the incentive to secure the network. A generous reward attracts more security but dilutes existing holders faster, while a shrinking one tightens new supply but leans more heavily on fees. None of that predicts price, and Crypto House covers it as mechanics, not investment advice.
Mining vs Staking, Explained
Key takeaways
- The block reward combines newly minted coins with the transaction fees from the block, paid to whoever produces it.
- It is how new supply is issued, so it directly sets a network's rate of inflation.
- On Bitcoin the minted portion halves about every four years, trending the network toward its fixed supply cap.
Block Reward — questions fréquentes
Is the block reward the same as transaction fees?
Not quite. The reward normally bundles two things: a subsidy of new coins created by the network, plus the fees users attached to the transactions in that block. Fees are one component of the total reward.
What happens to Bitcoin's block reward over time?
It keeps halving roughly every four years until the subsidy reaches zero, expected around the year 2140. After that miners would be paid entirely from transaction fees rather than newly issued coins.
