Bitcoin Halving is a cyclical event where the number of Bitcoin rewards generated for each mined Block will be cut in half (divided by two). In the upcoming halving, the number of bitcoins received by miners for each block that his mined will be reduced from 12.5 to 6.25 BTC. This process is part of the natural operation of Bitcoin and helps ensure the scarcity and stability of the total supply, which will eventually reach 21 million BTC.
The halving happens every 210,000 blocks; the 2020 halving will happen on block 630,000.
