One thing I know for sure is that, the Security architecture of BNB Blockchain has improved following it's hack.
You mean the latest hack? For sure they will add extra layer of security or any means to improve the defense as much as possible to avoid such panic and chaos on some of the holders of bnb. A hack could create panic selling and CZ and his team are fast to move and handle the problem. But shutting down the network is completely a big failure to a big chain like them. Well thats a con of being a centralized project but thumbs up for CZ doing a counter measure to the problem right away.
Everyone seem to hate the "Centralized" part of BNB but I mean to ask all of you this question, can crypto projects really do without centralisation? I doubt it, if things get real in few years time many projects forming decentralisation will switch to centralized entity, Mark my word, with regulations and strict rules that will affect crypto world in future decentralised projects will find it extremely harder to breath.
