Optimization of an existing Blockchain Because Blockchain has the main feature, namely smart contracts, while even existing ones we can use & maximize the smart contract without the need to provide hard tools to complete the block. NBC SWAP ,NBC NFT ,NBC VERSE are examples of Blockchain maximization that will be launched soon. alright, let me tell u something. The closest example, NBC SWAP uses the NBCex smart contract to exchange tokens on the BSC network but with a 40% cheaper fee. P2P is the same way, by sending tokens through the BCex smart contract but with a fee of 40% cheaper than sending tokens in a common way
