Flow blockchain today made a big news. A vulnerability in the execution layer was exploited by hackers, directly causing a $3.9 million hole. What was the result? The FLOW token dropped over 40% within 24 hours. Several platforms, including a major exchange, quickly suspended withdrawal services, and the scene was indeed a bit embarrassing.

Speaking of Flow, it once gained fame with the blockbuster NFT project NBA Top Shot, and was very popular. But during this update, a flaw appeared in the coordination mechanism of the execution layer. Although the foundation responded quickly, the damage had already been done. This incident actually exposed the true picture of the Layer 1 race—an error in logic can wipe out hundreds of millions of dollars in market value.

This should give those chasing high-performance public chains something to think about. Ethereum is indeed expensive and slow, but why do so many people still use it? Security. After more than ten years of market testing, stability is there. Compared to emerging public chains, while we enjoy their high performance, we also have to admit that the risks are indeed higher. So when allocating such assets, it’s best to diversify a bit—don’t put all your eggs in one basket. And when facing black swan events, don’t rush to buy the dip; wait until the official technical audits are completed, then you’ll have more confidence.
