⬛Purpose: BNB was initially launched as an ERC-20 token on the Ethereum blockchain in July 2017. It was primarily used as a utility token within the Binance ecosystem, providing discounts on trading fees for Binance users. However, BNB has since evolved to become the native cryptocurrency of the Binance Chain, Binance's own blockchain platform.
⬛Binance Chain: In April 2019, Binance launched the Binance Chain, a decentralized blockchain platform that enabled the issuance and trading of digital assets. BNB transitioned from being an ERC-20 token to a native cryptocurrency on the Binance Chain.
