Satoshi Nakamoto as the inventor of bitcoin limited the speed of bitcoin production by halving.
Bitcoin halving is cutting miner rewards in half.
This cut will occur after bitcoin production reaches 210 thousand. To achieve this production figure, Bitcoin takes approximately 4 years. So every 4 years the bitcoin miner's reward will be cut in half.
Halving will actually stop when 21 million blocks or bitcoins have been mined.
Simply put, Bitcoin halving is cutting the rewards miners receive in half.
