BSC was envisioned as an independent but complementary system to the existing Binance Chain. Dual-chain architecture is used, with the idea being that users can seamlessly transfer assets from one blockchain to another. In this way, rapid trading can be enjoyed on Binance Chain, while powerful decentralized apps can be built on BSC. With this interoperability, users are exposed to a vast ecosystem that can cater to a myriad of use cases. BEP-2 and BEP-8 tokens from Binance Chain can be swapped for BEP-20 tokens, the new standard introduced for Binance Smart Chain.
