### Overview of BEP 341
The BNB Chain has introduced BEP 341, a proposal aimed at significantly enhancing the transaction processing capacity and block production efficiency of the BNB Smart Chain (BSC). This proposal marks a shift from the current single-slot priority system to a model where validators can produce consecutive blocks, promising substantial improvements for the BNB Chain community.
### Motivation for BEP 341
The primary goal of BEP 341 is to optimize the efficiency of block production and increase transaction throughput on BSC. By allowing validators to produce consecutive blocks, the proposal aims to better meet the demands of BSC’s growing and active ecosystem. However, this change also presents potential risks, such as MEV (Maximal Extractable Value) abuse, which will require careful governance and monitoring to balance performance and security.
### Key Parameters of BEP 341
#### Number of Consecutive Blocks (n)
This parameter determines the number of consecutive blocks each validator can produce within each epoch.
#### AntiMEV Ratio
To mitigate potential MEV abuse, this setting adjusts the transaction fees’ split to the SystemRewardContract. As a validator’s consecutive block priority increases, the transaction fees’ split to the SystemRewardContract increases linearly, capped by the systemRewardAntiMEVRatio. This parameter initially starts at 0 and any changes require governance approval.
### Consecutive Block Production
Currently, BSC validators have priority block-producing rights for a single slot, rotating in a fixed order. This method limits transaction processing as it splits the workload between validating previous transactions and processing new ones.
BEP 341 proposes that validators gain priority block-producing rights for a continuous sequence of n slots per round, enhancing transaction processing efficiency. Subsequent blocks in a validator's sequence can skip transaction validation, focusing solely on processing new transactions, thereby significantly boosting Transactions Per Second (TPS), especially when n ranges from 3 to 5.
### Implementation Specifications
- **Fair Allocation:** Priority block-producing rights will be predefined for each epoch to ensure a fair process.
- **Validator Rotation:** The validator set will switch each epoch to maintain security and decentralization, preventing any small group from controlling the network.
- **Block Production Limits:** To avoid network dominance, block producers must produce fewer than n blocks within the previous ((validatorN/2+1)*n-1) blocks.
### Combating MEV with the AntiMEV Ratio
To prevent MEV extraction during consecutive block production, BEP 341 proposes increasing the transaction fees’ split to the SystemRewardContract linearly with the block number, capped by the systemRewardAntiMEVRatio. This approach ensures prompt transaction packaging, reducing MEV abuse risk and promoting network fairness. As more validators adopt Proposal Builder Separation (PBS), more MEV rewards will be included in gas fees, enhancing the AntiMEV mechanism's effectiveness.
### Benefits of BEP 341
- **Enhanced Efficiency:** Allowing consecutive block production will significantly improve block production efficiency and transaction throughput.
- **Decentralization:** By involving community-driven governance, BEP 341 supports greater decentralization and network resilience.
- **Fair Revenue Distribution:** The AntiMEV mechanism ensures fair revenue distribution among validators and delegators, preventing high-performance validators from gaining undue advantages.
### Conclusion
BEP 341 underscores the importance of adaptable, community-driven governance in blockchain ecosystems. By enhancing transaction processing capacity and involving the community in governance decisions, BSC aims to create a more efficient, fair, and decentralized network. Changes to key parameters like the number of consecutive blocks and the AntiMEV ratio will require community approval, reflecting BSC’s commitment to its users’ voices in the decision-making process.
