Is the blockchain vulnerable? --- A good question to ask here @Phannarith is whether or not this was a case of insecurity or a vulnerability in the fundamental blockchain technology itself, or the way that the DeFi platform (in this case, Poly Network) was deployed. As a reminder, in this particular case, the cybercriminals exploited a vulnerability in Poly Network ITSELF with Poly Network being a platform that attempts to connect different blockchains so that they can work together.
