What is the difference between Binance and Binance chain?

Could you please clarify the distinction between Binance, the cryptocurrency exchange, and Binance Chain, the blockchain network? As I understand, Binance is a popular platform for buying, selling, and trading various digital assets, while Binance Chain is a blockchain infrastructure designed to support the creation and issuance of digital assets, as well as decentralized applications. However, I'm curious to know if there are any key differences in terms of functionality, security, or other aspects that differentiate the two.
