The BNB Chain mainnet will activate the Pasteur hard fork at 02:30 UTC on August 25. Nodes must upgrade to the v1.7.7 client.
The core motivation for this fork is: "patch security holes + increase throughput". BEP-682 rejects duplicated validator signatures in cross-chain bridge validation, closing a vulnerability that allowed attackers to push past thresholds using a small number of real validators. BEP-695 reclaims management authority over old consensus keys to prevent blacklisted addresses from bypassing governance voting via signature spoofing. BEP-675 requires block builders to submit pre-executed blocks, reducing validator critical-path execution time from 125ms to 15ms, and lifting testnet TPS from 1237 to 2324.
Against the backdrop that cross-chain bridges have caused losses exceeding $4 billion since 2021, this upgrade feels more like BSC conducting a centralized settlement of its "security debt after high-speed blocks."
Short term 📉: The hard fork itself has been well anticipated. With "buy the rumor, sell the news" dynamics combined with the upgrade window charging/withdrawal pause, BNB faces a 59% probability of pullback while trading against resistance at $605–615. If the broader market (BTC/ETH) also retraces, the pressure will be greater.
Long term 📈: Network effects, cross-chain security, and the BEP-95 burn mechanism are strengthened, providing tangible support for demand of BNB as both gas and a staked asset. In the second half of the year, mainnet throughput could double, and if the AI L1 roadmap is implemented, it will open up the valuation upside ceiling.
Overall, Pasteur is BNB ecosystem’s "infrastructure capital increase," not a pulse catalyst—short-term volatility looks weak, with a medium-term bullish outlook.#BNB链将激活Pasteur硬分叉
