What is a Bitcoin Halving?
The Bitcoin halving is a condition defined in the Bitcoin protocol that requires the Bitcoin block reward to be halved every 210,000 blocks. The Bitcoin halving is possibly the most important event in the world of cryptocurrencies. Whether you’re a beginner in cryptocurrencies or an experienced investor, it’s essential to understand what halving is and its impact on the market.
-
It is expected that the Bitcoin halving will occur this week, reducing the mining reward to 3.125 bitcoins per block.
-
The first Bitcoin halving occurred in November 2012, and approximately every four years, the rate at which new bitcoins are created is reduced by 50%.
-
The halving reduces the supply of new bitcoins entering the market, which could lead to a price appreciation if demand remains constant or increases.
Although Bitcoin is digital money, it cannot be created infinitely, and verifiable scarcity is fundamental to its value proposition.
There are two key concepts related to scarcity that form the basis of the Bitcoin protocol:
First, there is a limited supply of Bitcoin. The protocol dictates that the total number of bitcoins that can exist is capped at 21 million, and it is impossible for more bitcoins to exist. This contrasts with fiat currencies, where more money can be printed at the discretion of the government or central bank, which could lead to inflation.
The second concept is known as halving. Approximately every four years, the Bitcoin mining reward, also known as the “block reward,” is halved. This means that the reward given to contributors securing the network is reduced by 50%, directly affecting the rate at which new Bitcoins are introduced into circulation.
In May 2020, the amount of new Bitcoins added to the network (every 10 minutes) through “virtual mining” was halved from 12.5 to 6.25. In April 2024, it will fall again to around 3.125, and the process will continue until all 21 million coins have been mined (which, according to estimates, should occur around 2140).
At that point, miners will rely solely on transaction fees to validate blocks.
In short, the Bitcoin halving is a policy to simply reduce what Bitcoin miners earn, but it is actually a device to control Bitcoin’s inflation rate. Unlike fiat currencies such as the euro or the U.S. dollar, which governments can produce at will, Satoshi Nakamoto developed strict limits. Therefore, there is a cap on the total supply of Bitcoin to avoid devaluation by the arbitrary issuance of new bitcoins. Moreover, the halving mechanism means that the supply of new Bitcoin decreases over time. In many ways, Bitcoin is similar to scarce commodities like gold, palladium, or other precious metals, but unlike those assets, we can calculate and predict how the supply decreases over time and how much Bitcoin remains to be mined.
