Halving Definition: Halving refers to splitting mining rewards in half and often refers to Bitcoin. This typically happens once every four years. This halving policy or process is written into the mining algorithm, which helps prevent the impact of inflation, which has a significant effect on other currencies.
This pre-set process is built into Bitcoin’s code, which is scheduled at specific times, once every four years, and effectively reduces the number of new coins issued on the blockchain by half. Bitcoin implemented this method to establish a measure of certainty, as many traditional markets are far more unpredictable.
