  "account": "BNB Chain executed the Pasteur hard fork on the Binance Smart Chain (BSC) on Tuesday, addressing bridge verification and validator authorization gaps while boosting transaction capacity. In a Tuesday announcement, BNB Chain confirmed the live implementation of Pasteur on the BSC mainnet. The upgrade bolsters the network's bridge, staking, and governance security, providing additional block capacity without altering its 450-millisecond block time. Three BNB Evolution Proposals - BEP-682, BEP-695, and BEP-675 - comprise the upgrade. BEP-682 prevents duplicate validator entries during cross-chain light-block verification, BEP-695 tightens controls on validator key rotation, slashing, and governance voting, and BEP-675 modifies how specialist builders submit blocks to validators. This upgrade eliminates validators from being counted multiple times in bridge approvals, revokes authority from outdated validator keys, and blocks restricted addresses from voting. The introduction of BEP-675 allows builders to submit already-executed blocks, enhancing the block-building process within the 450-millisecond block window. Pre-upgrade, transactions were executed twice before block submission, causing delays in busy periods and underfilled blocks. Tests conducted on BSC’s QANet environment revealed an 88% increase in transaction throughput, from 1,237 to 2,324 transactions per second, while average gas usage per block escalated from 46.35 million to 84.15 million within the unchanged 100-million gas limit and block interval. BNB Chain noted that these test results were based on controlled workloads and not mainnet measurements. The Pasteur upgrade follows previous hard forks aimed at reducing block times. BSC's Maxwell hard fork in June 2025 reduced the average block time from 1.5 seconds to approximately 0.8 seconds, and the subsequent Fermi upgrade further decreased it to 450 milliseconds.",
