The Bitcoin code specifies that the reward for validated Bitcoin transactions is halved every 210,000 blocks. How does halving work and why is it useful at all?

Gradual distribution of newly mined Bitcoins

The Bitcoin halving is a recurring event in which the reward provided for newly mined Bitcoin blocks is halved. As an essential function of the Bitcoin protocol, the recurring Bitcoin halving contributes to a gradual distribution of newly mined Bitcoins and ensures that the creation of new Bitcoins follows a predictable decline rate. In other words halving is a deflationary mechanism to reduce the circulating supply of a cryptocurrency and to increase shortage.

History of Bitcoin Halvings

The initial reward at the start of the Bitcoin payment network was 50 Bitcoin. The first Bitcoin halving took place on November 28, 2012 and the block rewards were reduced to 25 Bitcoin. On July 9, 2016 the block rewards were reduced to 12.5 Bitcoin during the second Bitcoin halving. The third Bitcoin halving occurred on May 11, 2020. The current Bitcoin block reward is 6.25 Bitcoin.


The next Bitcoin halving (fourth halving) will take place at block 840,000 and the Bitcoin block rewards will be slashed to 3.125 Bitcoin. It is estimated that the next halving will take place in spring 2024. For detailed information on the next halving date check our Bitcoin halving countdown.

Limited vs. unlimited supply

The Bitcoin halving is an essential element of the Bitcoin payment network, as it ensures that new Bitcoins are issued gradually, with a maximum supply of 21 million. With this controlled monetary inflation rate, Bitcoin stands diametrically opposed to traditional fiat currencies such as the U.S. dollar or the Euro, which typically have an unlimited supply.
