The term “Burn” in the context of cryptocurrencies refers to the process of permanently and irreversibly removing a certain number of tokens or coins from circulation. Once burned, these tokens can no longer be used or recovered and are effectively destroyed.
How does burn works?
The technical process of token burn is relatively simple and involves sending tokens to a special wallet address that is inaccessible. This address is often referred to as the “burner address” or “null address” and has no associated private key. Therefore, once tokens are sent there, no one can spend or move them.
The most common burner mechanisms are:
- Sending to a “dead” address: the simplest method. Tokens are sent to an address that is valid on the blockchain, but is not controlled by anyone (e.g., a randomly generated address for which no one owns the private key, or an address with a specific hash that guarantees that a private key will never be generated).
- On-chain mechanisms (smart contracts): Many projects use pre-programmed smart contracts that include a firing function. When this function is called, the contract programmatically destroys the tokens, removing them from the total circulation balance.
Why are tokens being burned? Purposes and reasons
Burning tokens is not a random act, but has well-defined economic and strategic purposes for a crypto project:
- Reduce supply and increase scarcity: this is the most common reason. By reducing the total number of tokens in circulation, a project attempts to create a deflationary effect. In theory, if demand remains constant or increases, a lower supply should lead to an increase in the value of the remaining token. It is similar to the way a company repurchases its own shares in the market.
- Price stabilization: Token burning can be used as a mechanism to stabilize the price or to counter inflation caused by the continuous issuance of new tokens.
- Reward/stimulus mechanism: Some protocols burn a portion of transaction fees, thus rewarding existing token holders by reducing supply and potentially increasing value.
- Proof ofBurn (PoB): Some networks use token burning as a consensus mechanism, where participants “burn” coins to gain the right to validate transactions and create new blocks. This demonstrates a commitment to the network.
- Error correction: In rare cases, mistakenly issued or incorrectly allocated tokens can be burned to correct errors.
- Inflation management: Projects with an inflationary model (where new tokens are continuously generated) can implement burn mechanisms to manage the inflation rate and maintain an economic equilibrium.
- BurningEvents: Some projects organize periodic burning events to reduce supply and generate excitement in the community. Binance Coin (BNB) is a classic example of a token that periodically burns a portion of its profits.
Implications of the burn process
- Price impact: Although token burning is often associated with price increases, it is not a guarantee. The price depends on many factors, including market demand, the actual usefulness of the token, general market sentiment, and the macroeconomic environment.
- Transparency: In a transparent blockchain, any token firing can be publicly verified, providing confidence in the process.
- Deflation vs. Inflation: Burned tokens contribute to a deflationary model, unlike fiat currencies which are often inflationary.
