It’s kind of like discovering a glitch in a video game that lets players cheat. This specific cheat is referred to as a “cycling attack”. In essence, someone could potentially exploit the lightning network by repeating certain actions in a way that wasn’t intended.

The Bitcoin community has tried to patch up this glitch, but there are concerns that it might not hold up against someone who really knows their stuff. Antoine, the guy who highlighted this issue, is basically saying, “Hey, we tried to fix it, but I’m not sure it’s completely secure. We need to be super careful moving forward.”

He’s emphasizing that when it comes to digital currency and security, you want to get things right from the get-go, because fixing mistakes after the fact can be really challenging.
