Bitcoin halving is an event that occurs roughly every four years, during which the reward for bitcoin miners is cut in half. This process is intended to regulate the amount of bitcoin rewards issued to miners for securing the network, and will continue until all 21 million bitcoins are mined. In this article, we'll explain how bitcoin halving works and what it means for the future of bitcoin.
What is Bitcoin Halving?
Bitcoin halving is a process that regulates the amount of bitcoin rewards issued to miners for validating transactions and securing the network. The total supply of bitcoin is capped at 21 million coins, after which no more bitcoins will be created. Since bitcoin is not run by any single entity, it requires miners around the world to participate in validating transactions and securing the network.
How Does Bitcoin Halving Work?
At the time of bitcoin's launch, the reward for every block added to the blockchain was 50 BTC. The code is set so that miners' rewards are cut in half for every 210,000 blocks added to the blockchain, which takes roughly four years to achieve. The first bitcoin halving occurred in 2012, with the reward cut to 25 BTC. The second halving took place in 2016, cutting the reward to 12.5 BTC. The latest halving event occurred in May 2020, cutting the reward to 6.25 BTC, with the next one expected in 2024.
What Does Bitcoin Halving Mean for Bitcoin?
Based on the basic principles of supply and demand, bitcoin halving tends to result in increased bitcoin prices if demand increases or remains constant. This is because the halving reduces the amount of new bitcoin entering the market, making bitcoin a scarce and thus valuable asset if demand continues to increase.
Will Bitcoin Cease to Exist After All Coins are Mined?
Estimates predict that the last halving will happen in 2140, after which miners will get zero block rewards for mining but will still be able to collect transaction fees for keeping the blockchain running. Ideally, the transaction fees will be enough incentive for miners to keep securing the network, ensuring that bitcoin will continue to exist for many years to come.
