Litecoin(LTC) Block Reward Halvin

What is a block halving event?

As part of Litecoin's coin issuance, miners are rewarded a certain amount of litecoins whenever a block is produced (approximately every 2.5 minutes). When Litecoin first started, 50 litecoins per block were given as a reward to miners. After every 840,000 blocks are mined (approximately every 4 years), the block reward halves and will keep on halving until the block reward per block becomes 0 (approximately by year 2142). As of now, the block reward is 12.5 coins per block and will decrease to 6.25 coins per block post halving.

Why was this done?

Litecoin was designed as a deflationary currency. Like gold, the premise is that over time, the issuance of litecoins will decrease and thus become scarcer over time. As litecoins become scarcer and if demand for them increases over time, Litecoin can be used as a hedge against inflation as the price, guided by price equilibrium is bound to increase. On the flip side, fiat currencies (like the US dollar), inflate over time as its monetary supply increases, leading to a decrease in purchasing power. This is known as monetary debasement by inflation. A simple example would be to compare housing prices decades ago to now and you'll notice that they've increased over time!
