If you have spent any time reading crypto announcements, you have probably seen a project say it "burned" some of its tokens. The word sounds dramatic, but the underlying mechanic is simple: a token burn is the permanent removal of a quantity of tokens from the circulating supply. Nothing is literally destroyed in a physical sense, because tokens are just entries in a shared ledger. What actually happens is that those entries are moved somewhere they can never be moved again, or deleted outright by the rules of the protocol.
There are two common ways this is done. The first is sending tokens to what is usually called a burn address or eater address. This is a wallet address that is valid on the network but has no known private key behind it. Because control of any crypto address depends on holding the matching private key, funds sent to an address with no key are unspendable forever. Anyone can look up that address on a block explorer and see exactly how much has been sent there, which makes the burn publicly verifiable. The second method is a built-in protocol or smart contract function, often literally named burn, which subtracts the tokens from a holder's balance and reduces the recorded total supply at the same time. This approach is cleaner because the supply figure itself changes rather than just the balance sitting in an unusable wallet.
Why would anyone deliberately give up tokens? The most frequently cited reason is supply management. Most tokens have a maximum or total supply written into their code. Burning shrinks the number of units that exist, which can be framed as a deflationary pressure on supply. It is important to be precise here: reducing supply changes only one side of the supply and demand relationship. If demand is flat or falling, a smaller supply does not automatically produce a higher price. Burns are a supply mechanic, not a value guarantee, and treating them as one is a common beginner mistake.
A second reason is fee-based burning built into a network's design. Some blockchains route a portion of every transaction fee into a burn rather than paying all of it to validators or miners. The effect is that network usage itself removes tokens from circulation, so supply changes dynamically with activity instead of by management decision. This is sometimes paired with ongoing issuance, meaning the network can be net inflationary or net deflationary depending on how busy it is at a given time.
A third reason is correcting an oversupply after a token launch. Projects sometimes mint more tokens than they end up needing, or fail to distribute an allocation, and burning the leftovers is a way of removing an overhang that would otherwise sit in a treasury wallet. Related to this, some tokens are burned as part of a redemption or backing mechanism. In certain stablecoin and wrapped-asset designs, tokens are minted when someone deposits a reserve asset and burned when someone redeems it, so the token supply tracks the collateral held. Here burning is pure accounting rather than a marketing event.
Burns also show up in governance and utility contexts. A protocol might require users to burn tokens to mint an NFT, register a name, access a service, or submit a proposal. In those cases the burn functions as a fee that is paid to nobody, which prevents spam and ties consumption of the token to actual usage of the product.
When you are evaluating a burn announcement, a few questions help separate substance from noise. Is the burn verifiable on chain, with an address or transaction anyone can check? Is it a one-time event or a recurring mechanism written into the protocol? Were the burned tokens actually in circulation, or were they locked in a treasury and never available to the market in the first place? Does the project still have the ability to mint new tokens, which could offset the burn entirely?
Understanding burns mostly means understanding that supply figures in crypto are programmable. Circulating supply, total supply, and maximum supply can each move for different reasons, and burning is one of the levers that moves them.
