BNB
Binance started its operations in 2017 and quickly launched an initial coin offering where it sold and allocated BNB tokens. At that time, Binance Coin (the name of BNB at the time) was an ERC-20 token on the Ethereum blockchain. However, in 2019, Binance launched a main blockchain called Binance Chain (BC), with BNB as its currency. The exchange conducted a token swap to convert ERC-20 BNB tokens to BNB coins built on the Binance Blockchain. In 2020, Binance Smart Chain (BSC) was launched as a separate compatible blockchain alongside Binance Chain.
In 2022, Binance merged the two environments of Binance blockchain and Binance Smart Chain under one brand: BNB Chain. Both blockchains continue to operate in parallel and serve distinct roles but under one name.
