Binance has announced a groundbreaking shift from its traditional quarterly BNB burn mechanism to a new automated system called "BNB Auto-Burn." Under this updated approach, BNB burns will no longer be tied to trading volume but will instead correlate with BNB's market price. The auto-burn process will continue until BNB’s circulating supply drops below 100 million tokens.
Previous BNB Burn Mechanism
Previously, Binance executed quarterly BNB burns based on a percentage of its trading revenue (initially set at 20% but later adjusted to reflect spot trading volumes). The goal was to systematically reduce BNB’s total supply by 50% (approximately 100 million BNB) over time.
How the New "BNB Auto-Burn" Works
The updated auto-burn formula incorporates the following key variables:
- B: Burn amount
- N: Total blocks produced on Binance Smart Chain (BSC) per quarter
- P: Average USD price of BNB (sampled every 10,000 blocks via oracle medians, roughly every 8.3 hours)
- K: Anchor price constant (initially set at 1,000, subject to future adjustments via governance proposals)
Simplified Calculation Example
Assuming a 90-day quarter:
- Blocks per hour: 1,200
- Total blocks per quarter (N): 2,592,000
If BNB Auto-Burn had been implemented earlier, and BNB's price surpassed $1,400, the projected burn curve would reflect higher burn quantities during price surges.
Dual Burn Mechanism
The new system enhances transparency by relying entirely on on-chain data, eliminating dependence on Binance’s quarterly revenue. Additionally, Binance Smart Chain (BSC) introduced BEP-95, a real-time burn mechanism inspired by Ethereum’s EIP-1559.
Key Features of BEP-95
- Dynamic Fee Burning: A fixed percentage of gas fees per block is burned.
- Governance-Adjustable Rate: Initial burn rate set at 10%, adjustable through validator voting.
Since its launch, BEP-95 has already burned 17,800 BNB (~$10.1M), contributing to BNB’s deflationary model. Notably, this mechanism remains active even after BNB Auto-Burn concludes (when circulating supply dips below 100 million).

CEO’s Perspective
Binance CEO Changpeng Zhao (CZ) emphasized that the BNB Auto-Burn aligns BNB closer to a DAO-like governance structure, reducing centralized exchange influences.
What’s Next?
Binance is expected to release its Q4 2021 burn report by mid-January—though it remains unclear whether the new auto-burn mechanism will apply retroactively.
FAQs
1. Why did Binance switch to an auto-burn system?
The new mechanism ensures burns are price-responsive, making BNB’s supply dynamics more predictable and decentralized.
2. How does BEP-95 complement the auto-burn?
BEP-95 accelerates burns through real-time fee destruction, reinforcing BNB’s scarcity independently of Binance’s revenue.
3. Will burns stop entirely once BNB supply hits 100 million?
Yes, BNB Auto-Burn ceases, but BEP-95 continues burning transaction fees indefinitely.
