In Bitcoin mining, Halving is an event scheduled to occur every 210,000 blocks, i.e. about 4 years, considering the time per block set at 10 minutes by the algorithm. As a result of Halving, the amount of BTC released as a reward to the mining nodes is reduced by 50%. This means that the issuance of new coins halves, decreasing the inflation of the cryptocurrency so that its scarcity is preserved. It is therefore possible to predict the pace of distribution of new Bitcoins, until the maximum availability of 21 million BTC is reached.
Bitcoin’s next halving, in particular, will take the block reward from 6.25 BTC to 3.125 BTC. The genesis block reward (3 January 2009), on the other hand, was 50 BTC: the miner who produced it was Satoshi Nakamoto, the creator of Bitcoin himself.
