BNB Chain Activates Pasteur Hard Fork on BSC to Strengthen Bridge Security
BNB Chain has activated the Pasteur hard fork on BSC, closing bridge verification and validator authorization gaps while introducing a new route to fit more transactions into each block.

The Pasteur hard fork strengthens the network's bridge, staking, and governance security while giving blocks more capacity without changing its 450-millisecond block time. It combines three BNB Evolution Proposals, including BEP-682, BEP-695, and BEP-675.
Imagine you're at a big party, and everyone wants to get in. The Pasteur hard fork is like a new way to let more people in, while making sure everyone is safe and following the rules. It helps the party (the BNB Chain network) run more smoothly and efficiently, so more people can join in and have fun.

BNB Chain's Pasteur Hard Fork: A Step Towards Enhanced Security and Capacity
The recent activation of the Pasteur hard fork on BNB Chain's BSC mainnet marks a significant milestone in the network's evolution. This upgrade aims to strengthen the network's bridge, staking, and governance security while increasing its transaction capacity. By combining three BNB Evolution Proposals (BEPs), BEP-682, BEP-695, and BEP-675, the Pasteur hard fork addresses several critical security gaps and improves the overall efficiency of the network.
Closing Security Gaps
The Pasteur hard fork closes bridge verification and validator authorization gaps, which were identified as potential vulnerabilities in the network. BEP-682 rejects duplicate validator entries during cross-chain light-block verification, while BEP-695 tightens controls involving validator key rotation, slashing, and governance voting. These changes ensure that validators are properly authorized and that the network's security is enhanced.
Increasing Transaction Capacity
The Pasteur hard fork also introduces a new route for submitting blocks to validators, which allows builders to submit blocks they have already executed. This change increases the network's throughput by about 88%, from 1,237 to 2,324 transactions per second, according to tests conducted on QANet, an internal environment designed to mirror BSC's geographically distributed validators. The new route also reduces the average gas used per block from 46.35 million to 84.15 million, while keeping the block interval and 100-million gas limit unchanged.
A Step Towards Competition
The Pasteur hard fork is a significant step towards making BNB Chain more competitive in the cryptocurrency market. By strengthening its security and increasing its transaction capacity, BNB Chain can attract more users and developers, which can lead to further growth and adoption. The network's ability to process more transactions efficiently will also make it more attractive to businesses and institutions looking to use blockchain technology for their operations.
Conclusion
In conclusion, the Pasteur hard fork is a significant upgrade for BNB Chain, which addresses several critical security gaps and improves the network's efficiency. By combining three BNB Evolution Proposals, the network has taken a significant step towards making itself more competitive in the cryptocurrency market.
Key points
- BNB Chain has activated the Pasteur hard fork on BSC, closing bridge verification and validator authorization gaps.
- The upgrade introduces a new route for submitting blocks to validators, increasing the network's throughput by about 88%.
- The Pasteur hard fork strengthens the network's security and increases its transaction capacity, making it more competitive in the cryptocurrency market.
- The upgrade combines three BNB Evolution Proposals, including BEP-682, BEP-695, and BEP-675.
If the Pasteur hard fork is successful, it could lead to increased adoption and growth for BNB Chain. This could result in more users, developers, and businesses joining the network, which would further increase its security and efficiency.
However, if the Pasteur hard fork is not implemented correctly, it could lead to security vulnerabilities and decreased efficiency. This could result in a loss of user trust and a decrease in the network's overall value.
