The process of adjusting the supply of tokens by permanently deleting a certain amount to strengthen security or improve utilities is known as token burning. Token burning is a common practice in the cryptocurrency industry, where it is used to reduce the total supply of a token, thereby increasing its scarcity and potentially driving up its value. Token burning can also be used to improve the utility of a token by reducing the number of tokens in circulation, which can help to prevent inflation and maintain the tokens value over time. The process of token burning can be controlled by the company that issued the token, which can sell new tokens to the market and buy out tokens from the market as needed.
