Which blockchain does BitDmark use?

BitDmark coin is using the popular Binance Smart Chain (BSC Blockchain).
Binance Smart Chain (BSC) is best described as a blockchain that runs in parallel to the Binance Chain. Unlike Binance Chain, BSC boasts smart contract functionality and compatibility with the Ethereum Virtual Machine (EVM).
This allows developers to port their projects from ETH to BSC. By implementing the EVM, BSC has access to the many tools and dApps of Ethereum, like MetaMask. BSC leverages interoperability so users can swap a handful of assets in the network.
