BEP-95

Intermediate

BEP-95 is a Binance Evolution Proposal that introduces a real-time burning mechanism to Binance Smart Chain. It’s been introduced to make BNB’s tokenomics even more dynamic and further decentralize the network.

With BEP-95, the network will burn a fixed ratio of each block’s gas fees that validators collect. The exact ratio will be determined via BSC’s governance mechanisms. The burns will take place even after BSC has reached its target goal of 100 million BNB. By reducing the supply of BNB, upwards pressure is placed on the coin’s price. The BEP may also decrease the amount of BNB delegators and validators received. However, with upward price pressure, the fiat value could also increase, offsetting any reduction in coins.

To technically implement this, the network collects each block’s gas fees and splits between two smart contracts:

1. System Reward Contract. 1/16 of gas fees will enter the System Reward Contract until it reaches a maximum of 100 BNB. These coins will be used as cross-chain package subsidies.
2. ValidatorSet Contract. All other gas fees will enter the ValidatorSet Contract and be shared daily with delegators and validators via Binance Chain.

To conduct a burn, the ValidatorSet Contract has a burnRatio variable. Upon finalizing each block, a validator will sign a transaction transferring its gas fees to the smart contracts. The deposit function contains burning logic that triggers the simple formula: burnRatio * gasFee. This sum will then be transferred to the burn address. The burnRatio will initially be set at 10%.

BSC Validators will be able to vote via proposals to change the burnRatio amount. This governance mechanism occurs on Binance Chain, and any community member can submit a proposal for review with a minimum deposit of 2,000 BNB. All BNB staked behind a proposal and in a vote is returned after a decision has been made. Quorum is reached at 50%, and the change will be implemented via cross-chain communication immediately.
