Changpeng Zhao, the founder of cryptocurrency exchange Binance, officially announced on Twitter this morning that the company’s associated blockchain has been suspended. The reason is a hacker attack on the BSC Token Hub, a cross-network bridge for moving BEP-2 and BEP-20 format tokens, which led to the emission of an additional BNB service token.

Let’s grow together!
The Binance ecosystem runs on two parallel blockchains: the Binance Smart Chain (BSC) and the Binance Chain:
BNB Chain has published an update in which hacker accounts will be blocked, and transactions between BNB Beacon Chain and BNB Chain will be halted.
The network is up and running again, and the bridge vulnerability has been fixed. Venus Protocol and Binance report that everything is working normally again.
The BNB coin fell about 4% in today’s trading session on this negative news.
Due to the complexity of the contracts, the speed at which this space moves as a whole and the immeasurable amount of variables you need to take into account. It’s almost impossible to be completely bug free. It doesn’t matter how many web3 programmers there are, something as complex as this will always have weaknesses that can be exploited in some way, either for example due to a small code error, badly set parameters or just brute force.
Even the biggest chains and protocols who have the best people and test everything regularly and thoroughly will still have some flaws and weaknesses. I’m sure there are large, big brain and well funded teams worldwide who actively search for these kind of exploits cause the potential payday can be massive. It will happen time and time again and i’m sure we’ll see more of it in the future.
