etc. We'll write about 600 words. Let's write the article in plain text first, then convert to HTML. Draft: BNB Chain has activated the Pasteur hard fork on BSC, the network's main blockchain. The upgrade closes security gaps in the bridge and validator components and targets a greater capacity for transactions. The Pasteur hard fork is now live. For blockchain networks, a hard fork is a permanent change to the protocol. This one is aimed at two specific areas: the bridge that lets users move assets between chains, and the validators that confirm transactions and keep the network running. The security changes are the headline. BNB Chain has been working to strengthen its infrastructure, and the Pasteur upgrade is part of that effort. The hard fork addresses vulnerabilities in the bridge and validator set, though the exact vulnerabilities aren't disclosed. Beyond security, the upgrade targets transaction capacity. That means BSC is expected to handle a larger volume of transactions without sacrificing performance. The network has seen increasing usage, and the capacity boost is a direct response to that. What does this mean for users? For now, nothing changes immediately. The upgrade is part of the network's normal evolution. Validators and node operators are required to run the new software to stay on the network, but regular users don't need to do anything. The Pasteur hard fork is a step forward for BSC. The next question is whether the security fixes hold up under real-world attacks. The network will continue to operate, and the effects of the upgrade will show in the coming blocks. But we need to avoid vague "coming blocks" - we can say "the next step is to monitor the network's performance." That's not a concrete next step. Better to end with a specific fact: "The hard fork is now part of BSC's history. The network will now run with the new rules, and any further upgrades will follow a similar process." But we need a concrete next thing. Since we don't have date, we can say "The activation is complete. The next hard fork, if any, hasn't been announced." That is not good. Maybe we can say "The Pasteur hard fork is now active. Validators and node operators have to ensure they are running the latest version to continue participating." That is a concrete next step for them. But we don't know if they have to. But it's a logical requirement. We can say "The upgrade is now live. For the network to function properly, all validators must have updated to the new version." That is a fact about hard forks, but not from the facts. We can't invent that. Given the constraints, we can end with: "The activation of the Pasteur hard fork is complete. The focus now shifts to how the network performs under the new rules, and whether the security gaps are truly closed." That is an unresolved question, but it's grounded. We'll write that. Now we need to write the JSON. Ensure content is in HTML. Let's write the article properly. I'll write about 600 words. Title: "BNB Chain Activates Pasteur Hard Fork on BSC to Fix Bridge and Validator Security" - but that's a bit long. "BNB Chain's Pasteur Hard Fork Goes Live on BSC" - but doesn't mention security. Better: "Pasteur Hard Fork Live on BSC, Targeting Security and Capacity" - but we need to be factual. Let's go with: "BNB Chain Activates Pasteur Hard Fork on BSC" - but that's too short. I'll add: "BNB Chain Activates Pasteur Hard
