How many blocks are mined between each Bitcoin halving?
Answer
210,000
How many blocks are mined between each Bitcoin halving? Bitcoin’s block reward halves every 210,000 blocks.
The halving is part of Bitcoin’s issuance schedule. When the network launched in 2009, miners received 50 BTC per block. After the first 210,000 blocks, the reward fell to 25 BTC; later halvings reduced it to 12.5 BTC in 2016, 6.25 BTC in 2020, and 3.125 BTC in 2024.
Because Bitcoin targets an average block interval of about 10 minutes, 210,000 blocks represents roughly four years, although actual calendar timing varies with changes in mining difficulty and network conditions. Difficulty is adjusted every 2,016 blocks to keep block production near that average.
The halving reduces the rate at which new bitcoins enter circulation. It does not halve users’ existing balances, transaction fees, or the size of each block. The schedule is designed to approach Bitcoin’s supply limit of about 21 million coins, with the final issuance expected around 2140.
