In the field of security research, few can compare to Dan Kaminsky. This legendary security expert once discovered a fatal vulnerability in the DNS system that nearly brought the entire internet to a halt. In 2011, he turned his attention to Bitcoin.

At that time, Kaminsky's idea was straightforward: a financial software developed by an anonymous person, no matter how clever, could never be perfect. He decided to verify it in his own way—by launching full-force attacks.

He began searching for vulnerabilities. Network attacks, logical validation breaches, timestamp manipulations... He identified about nine different potential attack methods, all of which had proven effective in his previous work.

But what happened next shocked him. All these vulnerabilities had already been fixed. Not after he discovered them, but quietly corrected before he even found them.

Kaminsky realized he was not dealing with a clever programmer, but a true genius. This person’s understanding of security threats was so profound that they could anticipate attack paths only a handful of top security experts in the world would consider. In interviews, he openly stated that the person who wrote this program was incredibly skilled—far from amateur level.

Ironically, the public often mythologizes Satoshi Nakamoto, treating him as an elusive legend. But Kaminsky’s experience provides concrete proof: the world’s top security experts tried their best to break this system, only to find that their opponent had already foreseen every move.

Kaminsky passed away in 2021, never revealing the true identity of Satoshi Nakamoto. But in a way, he answered a question with the most convincing evidence—how secure is this system? The answer is: secure enough to make even the world’s top hackers helpless.
