Halving
A halving is a scheduled event in certain cryptocurrencies where the reward paid to miners for adding a new block is cut in half, slowing the pace at which new coins enter circulation.
The close-up. Many proof-of-work networks pay miners a fixed amount of newly created coins each time they add a block to the blockchain. A halving is a rule, written into the protocol itself, that periodically reduces this block reward by half. It triggers automatically after a set number of blocks have been produced, not on a calendar date, so its timing depends on how quickly blocks are found. Because the rule is enforced by every node running the software, no single party can pause it, skip it, or change the amount without broad agreement across the network.
The wide shot. Halvings exist to control supply. Many of these coins have a fixed maximum that will ever exist, and cutting the reward at regular intervals stretches issuance out over a very long horizon while making the schedule fully predictable. This design contrasts with currencies whose supply can be expanded at will, and it is often described as programmed scarcity.
A common misconception is that a halving guarantees a rising price. It changes only the rate of new issuance, not demand, and its effects are already known to the market well in advance. The event is best understood as a supply-side mechanic to study alongside mining economics and network security — not as a signal to act on. Always do your own research.
