Recently, this wave of cooling has been truly intense. In the Northeast, temperatures are below -40°C, and even the South hasn't escaped—Guangxi, Guangdong, and Fujian are all approaching freezing point. Only Hainan is still wearing short sleeves, which is really comfortable.

But there's an interesting phenomenon here—places without heating, where hand operations for chain scanning have become a big problem. It's not just cold; what's more painful is that it directly affects transaction speed. Think about it—if your fingers are frozen stiff, how can you maintain fast key presses without missing chains?

Speaking of which, the impact of geographical location on network latency is underestimated. The South is close to Hong Kong, with a short physical distance, giving an inherent advantage in ladder (proxy) latency. Many high-frequency traders on-chain tend to gather in the South, and it's not without reason—early deployment of network infrastructure, high fiber density—all these translate into millisecond-level advantages. In the MEV bidding war, a latency difference of just a few milliseconds can determine the success or failure of sniping.

So, what seems like casual weather talk actually reflects a reality: the competition in blockchain transactions, from technology to hardware to geographical location, is fought over every detail.
