The Bitcoin halving event is a programmed feature in the Bitcoin protocol that occurs approximately every four years or after every 210,000 blocks are mined[^1].

During the halving event, the reward for miners who validate transactions and add new blocks to the blockchain is reduced by half. This means miners receive 50% fewer Bitcoins for their computational work on the network[^2].

The halving event is crucial as it decreases the rate at which new Bitcoins are created, contributing to the cryptocurrency's scarcity, which is a key factor in determining its value[^3].

Bitcoin's design is deflationary, with a capped supply of 21 million coins. Each halving reduces the block reward, gradually decreasing the number of Bitcoins entering circulation[^4].

Historically, Bitcoin halving events have been associated with bullish trends in Bitcoin's price. The reduction in the supply of new Bitcoins entering the market can lead to an increase in demand, potentially driving up the price of Bitcoin[^5].
