Burning

The primary economic function of burning is to create scarcity. By permanently removing tokens from the circulating supply, the protocol aims to increase the relative value of each remaining token, assuming demand remains constant or grows. This is a direct application of basic supply-and-demand economics to a digital asset.

• Example: If a project with 1 billion tokens burns 100 million, the remaining supply is 900 million, making each token represent a larger share of the total network.

Proof-of-Burn (PoB) is a consensus mechanism where miners or validators demonstrate commitment to the network by destroying (burning) native or alternate chain tokens. This act grants them the right to mine or validate blocks proportionally. It's an energy-efficient alternative to Proof-of-Work (PoW) that uses 'virtual' computational power represented by destroyed value.

• Key Concept: Burning acts as a sunk cost, aligning validator incentives with the long-term health of the new chain.

Introduced in Ethereum's EIP-1559 upgrade, this mechanism burns the base fee portion of every transaction. The base fee is algorithmically determined and destroyed, making Ether a deflationary asset during periods of high network usage. This creates a direct link between network utility (gas consumption) and supply reduction.

• Statistic: Since its implementation, over 4 million ETH has been burned via EIP-1559, permanently removing it from supply.

Common with decentralized autonomous organizations (DAOs) and projects with treasury revenue. The protocol uses a portion of its profits (e.g., from transaction fees or protocol revenue) to buy back its own tokens from the open market. These purchased tokens are then sent to a burn address. This mechanism is analogous to a corporate stock buyback, directly returning value to token holders.

• Example: Binance Coin (BNB) executes quarterly buyback-and-burn events using a percentage of its exchange profits.

Burned tokens are sent to a cryptographic burn address—a wallet whose private keys are provably unknown or nonexistent. The most common is the Ethereum zero address (0x000...000). Because all transactions are recorded on the public ledger, any user can cryptographically verify that:

• The tokens were sent.
• The destination address cannot spend them.
• The supply reduction is permanent and tamper-proof.

Burning is a key lever in a project's tokenomics. It can be used to:

• Offset inflation from staking rewards or token emissions.
• Signal commitment by developers burning their own allocations.
• Governance tool where burning tokens can be a vote or action within a DAO.
• Create deflationary assets where the supply continuously decreases over time, contrasting with inflationary fiat currencies.

The primary economic function of burning is to permanently remove tokens from circulation. This creates a deflationary pressure on the remaining supply, which can counteract inflation from new issuance or staking rewards. Key mechanisms include:

• Buyback-and-burn: Protocols use revenue to buy and destroy their own tokens.
• Transaction fee burns: A portion of every transaction fee is destroyed (e.g., Ethereum's EIP-1559).
• Targeted supply reduction: Adjusts tokenomics to increase scarcity over time.

In Proof-of-Burn (PoB) consensus mechanisms, burning tokens serves as the cost to participate in network security and block production. Users send tokens to an unspendable address (e.g., 0x000...dead) to demonstrate commitment, which grants mining rights or a new native token on a parallel chain. This is an alternative to the energy expenditure of Proof-of-Work or the capital lock-up of Proof-of-Stake.

Burning acts as the destruction mechanism in two-way asset pegs and wrapping protocols. To redeem the underlying asset, the representative token must be burned. Examples include:

• Wrapped BTC (WBTC): Burning WBTC on Ethereum triggers the release of native BTC from custody.
• Bridge withdrawals: Burning assets on a destination chain unlocks them on the source chain.
• Cross-chain messaging: Validators burn tokens as proof to finalize a message.

Burning tokens can be a costly signal in decentralized governance. Projects may implement vote-burning mechanisms where governance tokens are burned to cast a vote, aligning voter incentives with long-term success. It also functions as a spam-prevention tool, where submitting a proposal or transaction requires burning a small, non-refundable fee to discourage malicious or frivolous activity.

Burning enforces protocol rules and corrects errors. In Proof-of-Stake systems, slashing often involves burning a portion of a validator's staked tokens as a penalty for malicious behavior (e.g., double-signing). It also acts as a final remedy for irrecoverable operational errors, such as tokens mistakenly sent to a contract without a withdrawal function, where a governance-approved burn is the only way to remove them from supply.

Burning can directly distribute value to token holders by increasing their proportional ownership of the network. When a protocol burns tokens using its revenue, it functions similarly to a share buyback in traditional equity markets. The reduction in supply, all else being equal, increases the scarcity and potential value of each remaining token, benefiting long-term holders.

The primary economic use of burning is to create a deflationary pressure on a token's supply. By permanently removing tokens, the protocol aims to increase scarcity, which can support the value of remaining tokens if demand is constant or growing. This is often used as a counterbalance to inflationary token emissions from staking or mining rewards.

• Example: Binance Coin (BNB) uses quarterly burns based on exchange profits to reduce its total supply from 200 million to 100 million tokens.

Many networks burn a portion of the transaction fees (gas fees) paid by users. This turns fee expenditure into a deflationary mechanism rather than rewarding validators/miners with all fees. It aligns network security incentives with token scarcity.

• EIP-1559 (Ethereum): A base fee is burned for every transaction, making ETH a potentially deflationary asset during high network usage.
• Polygon: Implements a similar fee-burning mechanism on its PoS chain.

In Proof-of-Burn (PoB) consensus mechanisms, burning tokens serves as the cost to participate in network validation, analogous to the hardware investment in Proof-of-Work. Users send tokens to a verifiably unspendable address to "mine" or earn the right to validate blocks.

• Slimcoin: An early cryptocurrency implementing PoB, where burning coins grants mining power.
• Counterparty (XCP): Created by burning Bitcoin, establishing initial distribution without an ICO.

Burning is a critical technical function in cross-chain bridges and wrapped asset systems. To move an asset from one chain to another, the original asset is locked or burned on the source chain, and a representative token is minted on the destination chain. The reverse process involves burning the wrapped token to unlock the original.

• Wrapped BTC (WBTC): BTC is custodied, and WBTC is minted on Ethereum. Redeeming WBTC burns it to release the underlying BTC.
• Bridge Security: Burning on the source chain provides cryptographic proof for minting on the destination.

Projects use burns to execute tokenomic adjustments or respond to governance decisions. This can include burning unsold tokens from a sale, burning a treasury's excess holdings, or removing tokens from circulation after a governance vote to adjust incentives.

• Initial DEX Offerings (IDOs): It's common to burn unsold tokens after a liquidity event.
• Treasury Management: DAOs may vote to burn a portion of treasury assets to benefit all token holders proportionally.

A core feature of on-chain burning is its public verifiability. Burns are recorded as transactions to a "burn address"—a cryptographically generated address with no known private key (e.g., 0x000...dead). This creates an immutable, auditable record of the permanent supply reduction.

• Burn Addresses: Ethereum's common burn address is 0x000000000000000000000000000000000000dEaD.
• Block Explorers: Anyone can track the balance of a burn address to verify the total burned supply in real-time.
