Halving means a 50% reduction in the production and issuance rates of new coins and block subsidies for miners. This usually happens after specific intervals, and is designed to stabilize a digital currency’s issuance rate during the mining process.

For every new block a miner “discovers,” the blockchain produces a new coin as a reward. Halving cryptocurrency issuance rates ensures that new coins or tokens are made at a controlled rate, essentially regulating the crypto mining process.​
