Binance has officially announced the replacement of its long-standing quarterly BNB burn mechanism with a new protocol called BNB Auto-Burn. This marks a significant shift in how BNB supply reduction is managed, moving away from transaction volume-based calculations to a more transparent, on-chain, price-responsive model. The new system aligns BNB’s deflationary mechanics more closely with market dynamics and decentralization principles.
Under the updated framework, BNB burns will no longer be tied to Binance’s quarterly profits or trading activity on the exchange. Instead, the burn amount will dynamically respond to the market price of BNB. Additionally, once the total circulating supply of BNB drops below 100 million tokens, all burning mechanisms under this program will cease entirely.

Understanding the Original BNB Quarterly Burn
Since its inception, Binance committed to reducing the total supply of BNB by 50%—from an initial 200 million to 100 million tokens—through periodic burns. Initially, the amount burned each quarter was calculated based on 20% of Binance’s profits. Later, this evolved into a model where the burn size depended on spot trading volume across the platform.
This approach ensured consistent reductions in supply and rewarded long-term holders by creating scarcity. However, it also introduced opacity, as users had to rely on Binance’s internal financial reporting to verify burn amounts. Critics pointed out that this centralized method limited transparency and made it difficult to independently validate results.
Introducing BNB Auto-Burn: A Transparent, On-Chain Formula
The new BNB Auto-Burn mechanism leverages blockchain data and decentralized pricing oracles to calculate burn quantities automatically and verifiably. According to Binance’s official announcement, the formula for each quarterly burn is:
B = N × K / P²
Where:
- B = Number of BNB tokens burned
- N = Total number of blocks produced on BNB Smart Chain (BSC) in a quarter
- K = Anchoring constant (initially set at 1,000)
- P = Average USD price of BNB per 10,000 blocks, sampled using on-chain price oracles (approximately every 8.3 hours)
For a typical quarter (~90 days), with BSC producing one block every 3 seconds:
- Blocks per hour: 1,200
- Total blocks per quarter: 2,592,000
This means the burn volume adjusts inversely with the square of the BNB price. As the price increases, fewer tokens are burned—and vice versa. This creates a self-regulating economic model that responds to market conditions without requiring centralized intervention.
For example:
- If BNB averages $500, burn volume would be significantly higher.
- If BNB rises above $1,400, burn amounts decrease proportionally.
This design encourages stability and aligns incentives across stakeholders by making supply contraction responsive to real-time valuation.

Dual Burn Mechanisms Enhance Deflationary Pressure
One of the most powerful aspects of the new ecosystem is the coexistence of two independent burn mechanisms:
1. BNB Auto-Burn (Quarterly)
- Occurs every quarter based on the formula above
- Fully transparent and verifiable via on-chain data
- Ceases when circulating supply falls below 100 million
2. BEP-95 (Real-Time Burn)
Launched in late 2021, BEP-95 introduces a permanent, real-time burn mechanism inspired by Ethereum’s EIP-1559.
Key features:
- A portion of gas fees paid in BNB on BSC is automatically destroyed with every block
- The burn rate is adjustable through community governance via BEP proposals and validator voting
- Initial burn rate set at 10%, with potential future changes based on consensus
Data from BurnBNB shows that since BEP-95’s activation, over 17,800 BNB (valued at approximately $10.1 million at the time) has already been permanently removed from circulation.
Crucially, BEP-95 will continue operating even after the Auto-Burn program ends, ensuring ongoing deflationary pressure beyond the 100 million supply threshold.
This dual-layer approach strengthens BNB’s value proposition by combining predictable quarterly burns with continuous, usage-driven destruction—a powerful synergy for long-term holders.
Toward Decentralization: BNB as More Than a Utility Token
Binance CEO Changpeng Zhao (CZ) emphasized that this transition brings BNB closer to becoming a decentralized autonomous organization (DAO) asset rather than just an exchange utility token.
By removing reliance on centralized financial metrics like exchange revenue and shifting to algorithmic, on-chain triggers, the protocol enhances transparency and trustlessness. Users can now verify burn events independently using public blockchain data—no third-party audits required.
This evolution reflects broader industry trends toward decentralized governance and programmable economics, positioning BNB as a more mature digital asset within the Web3 ecosystem.
Frequently Asked Questions (FAQ)
Q: What happens when BNB circulation drops below 100 million?
Once the circulating supply reaches 100 million BNB, the BNB Auto-Burn program will stop permanently. However, BEP-95 burns will continue, meaning some deflationary pressure remains as long as BSC is actively used.
Q: How does the price affect the burn amount?
The burn amount is inversely proportional to the square of the BNB price. Higher prices lead to smaller burns; lower prices trigger larger burns. This helps stabilize supply adjustments during volatile markets.
Q: Is the anchoring constant K fixed forever?
No. While K starts at 1,000, it can be modified through a formal BEP proposal and community voting process on BSC, allowing flexibility as market conditions evolve.
Q: Can users track burns in real time?
Yes. Both BEP-95 and Auto-Burn events are recorded on-chain. Tools like BurnBNB provide live dashboards showing cumulative burns, block-by-block destruction, and historical trends.
Q: Does this make BNB deflationary?
Partially. With two active burn mechanisms and capped supply, BNB exhibits deflationary characteristics under certain conditions, especially during high network usage or sustained low prices. However, inflation from validator rewards may offset some effects.
Q: Will the first Auto-Burn happen in Q1 2025?
Binance has not confirmed whether the upcoming Q4 2024 burn (expected January 2025) will use the old or new system. An official update is anticipated soon.
