Which network supports Binance?

Could you elaborate on the networks that support Binance? I'm interested in understanding the infrastructure and partnerships that allow Binance to operate efficiently and securely. Specifically, are there any blockchain networks that Binance utilizes for transactions or do they have proprietary solutions in place? Additionally, what are the benefits and drawbacks of these networks in terms of speed, scalability, and security? I'm seeking a comprehensive overview of the technical foundations that underpin Binance's operations.
