halving
Scheduled event where cryptocurrency mining rewards automatically cut in half.
A halving is a programmed event built into certain cryptocurrencies—most notably Bitcoin—where the amount of new coins miners receive for validating transactions drops by 50%. Bitcoin’s code automatically triggers this roughly every four years (every 210,000 blocks mined). After the first halving in 2012, miners earned 25 Bitcoin per block instead of 50; after the second in 2016, it fell to 12.5, and so on.
Halvings exist to control inflation by limiting the total supply of coins that can ever be created. They reduce mining incentives over time, making it progressively less profitable to mine. When you see a halving mentioned in news, it signals an upcoming shift in the economics of that cryptocurrency—miners may face pressure to remain profitable, and the reduced issuance of new coins can influence market dynamics and speculation about price movements.
