- BNB Chain's Pasteur hard fork activated on August 25, introducing key improvements to block processing, cross-chain verification, and validator governance.
- Controlled tests on QANet showed throughput reaching 2,324 TPS, a significant jump from 1,237 TPS, though mainnet performance may vary.
- Node operators must upgrade to client version 1.7.7 before activation, while regular users and most developers need no action.
- BNB Chain also leads tokenized equities with bStocks, surpassing $1.3 billion in supply, and launched a framework for sovereign stablecoins with Sign.
BNB Chain has officially activated its Pasteur hard fork on August 25, marking a major step forward for the network’s performance and security. The upgrade, which was mandatory for all BSC mainnet nodes, brings a series of technical improvements that could reshape how the blockchain handles transactions and cross-chain interactions. While the most eye-catching result comes from controlled tests showing throughput reaching 2,324 transactions per second, the network has been careful to note that real-world mainnet conditions may differ.
The Pasteur upgrade combines three key proposals—BEP-675, BEP-682, and BEP-695—each targeting a different aspect of BSC operations. From faster block production to stricter validator governance, these changes are designed to make the network more efficient and secure. For everyday users and most developers, the transition should be seamless, but node operators had to act quickly to ensure their clients were updated before the hard fork went live.
Pasteur Hard Fork: Performance Gains and Technical Details
The performance improvements from Pasteur are the most striking, with BEP-675 changing how builders and validators handle block execution. Under the new approach, builders can submit blocks they have already executed, and validators then check the proposed block against consensus rules before signing and broadcasting it. This shift in the block production process has shown impressive results in testing, with critical-path processing time dropping from 125 milliseconds to just 15 milliseconds on QANet, an internal test environment designed to mirror BSC’s cross-region validator setup.
Throughput also saw a substantial boost, jumping from 1,237 TPS to 2,324 TPS in these controlled tests. Average block gas usage rose from 46.35 million to 84.15 million, still within the existing 100 million limit. However, the 450-millisecond block interval remained unchanged, as did finality lag. BNB Chain has emphasized that these figures come from controlled testing rather than live mainnet activity, so the actual performance under real-world conditions could vary.
Beyond the performance gains, Pasteur also introduces important changes to cross-chain verification through BEP-682. The network will now check validator signatures before accepting information from another chain, confirming that the required voting threshold approved the submitted block. This proposal also closes a validator-set verification gap that previously allowed specially constructed sets to repeat the same validator and count its voting power more than once. With BEP-682, duplicate validator entries are rejected, making the voting limit reflect the actual validator supermajority.
BEP-695 addresses consensus-key rotation and governance permissions. After Pasteur activates, an old consensus key will lose its administrative authority when a validator changes keys. Pending slash evictions will also transfer to the validator’s new key rather than disappearing during rotation. The proposal also prevents blacklisted addresses from using signature-based governance voting methods to circumvent restrictions on direct votes. These changes operate through BSC staking, governance, and system contracts, meaning existing applications do not require migration.
Node Operators Must Upgrade Before Activation
Node operators were required to install BSC client version 1.7.7 before the hard fork, and they also needed to remove from config.toml. Leaving this setting in place would prevent the updated client from starting. The release also recommends removing , while several command-line flags have become obsolete or inactive. Pasteur has been operating on BSC testnet since July 21, giving developers and node operators time to prepare for the mainnet activation.
After the Aug. 25 mainnet activation, the next measurable result will be whether the 2,324 TPS recorded on QANet appears under live network conditions. This will be a key indicator of how well the upgrade translates from controlled testing to real-world usage.
BNB Chain’s Meme Campaigns and Market Impact
In addition to the Pasteur upgrade, BNB Chain has been actively driving activity in the meme token space through targeted trading campaigns. The chain launched a $100,000 Flap trading campaign running from August 19 to 28, and a separate Four.meme profit and loss contest of another $100,000 from August 24 to September 2, both rewarding active traders of BNB Chain meme tokens. These incentives have coincided with a strong move in several BNB Chain memes, including BinanceLife (币安人生), which gained about 10.6% in a 24-hour window with roughly $24.6 million in daily volume and a market cap around $535 million.
The broader BNB Chain meme category market cap was up over 8% in 24 hours with roughly $127 million in volume, while the global memecoin market rose more than 10% in the same period. This pattern fits a typical sequence where Bitcoin and large caps rally first, then speculative appetite extends into thinner liquidity segments like memecoins, especially those on active ecosystems such as BNB Chain. The move in BinanceLife appears to be more about sector rotation and chain-level incentives than any new project-specific news.
Sovereign Stablecoin Framework with Sign
BNB Chain has also partnered with blockchain infrastructure provider Sign to publish a new framework aimed at helping governments issue regulated national stablecoins. The Sovereign Stablecoin Framework, announced on August 26, establishes a model in which public blockchains such as BNB Chain handle settlement and distribution of digital currencies, while licensed local financial institutions manage token issuance, reserve custody, and regulatory compliance under rules set by national authorities.
Sign emphasized that a credible sovereign stablecoin requires more than a digital token. The company argued that such a system needs a legal foundation, verifiable backing reserves, and accessible redemption mechanisms for currency holders. The framework assigns distinct responsibilities across three layers: public blockchains operate the settlement and distribution network, local financial institutions execute issuance and maintain reserves, and regulatory authorities define standards and oversee operations.
Kyrgyzstan’s national stablecoin, KGST, serves as the first real-world implementation of the framework. In that arrangement, Kyrgyz authorities define the operational rules, while domestic financial institutions oversee reserves and manage fiat-to-crypto conversion. Sign supplies the underlying technical infrastructure, with BNB Chain acting as the public settlement layer. Both companies pointed to KGST as a working demonstration of the model, suggesting it could be adapted by other countries exploring national stablecoin programs.
Tokenized Equities and RWA Market Position
BNB Chain’s tokenized-equity initiative, bStocks, has reshaped the market hierarchy, turning steady growth into clear leadership after June. Before the launch of bStocks, Ethereum controlled the largest supply of tokenized equity, while BNB Chain remained below $500 million despite months of gradual expansion. However, bStocks accelerated growth, carrying BNB Chain beyond $1.3 billion by the end of August compared to Ethereum at around $800 million. Solana also saw an increase to around $550 million, while Avalanche maintained around $170 million.
According to BlockWorks data, these supply figures have given BNB Chain an early 50% share of the total supply of nearly $2.9 billion in the tokenized equity space. bStocks provides two additional benefits that do not exist with traditional shares: 24/7 settlement capabilities and composability. There are now more than 67 active assets supported by bStocks, with trading already exceeding $19 billion, showing those assets are circulating actively rather than simply remaining issued on-chain.
However, when viewed across the wider RWA market, BNB Chain represents $5.7 billion of the $38.4 billion total RWA distributed market share, making up approximately 15% of the market. Ethereum controls $17.27 billion, or about 45%, while Solana follows BNB Chain with $4.06 billion. Therefore, its tokenized-equity lead has still not been able to create a similar level of RWA sector leadership. Expanding into Treasuries and Funds will help to spread out demand for BNB Chain and also increase capital retention.
Overall, BNB Chain is making significant strides across multiple fronts. The Pasteur hard fork brings technical improvements that could enhance network performance and security, while the meme campaigns and stablecoin framework demonstrate the ecosystem’s growing versatility. The tokenized equity leadership shows real traction, but the broader RWA market still favors Ethereum. As the network continues to evolve, its ability to maintain momentum in these areas will be crucial for closing the gap with its competitors.
