Binance CEO Changpeng 'CZ' Zhao recently said Binance Chain is not a competitor to Ethereum ($ETH), a statement Tony Sheng decries as pure PR. If Binance Chain doesn't have smart contract protocol, how can it compete against Ethereum, CZ questioned. Sheng rebuttals, asking what's stopping Binance Chain from adding smart contracts themselves or once Cosmos' ($ATOM) interoperability comes online? CZ's comment was a nod to the development wars, the next step for smart contract markets. In the midst of the chaos, two sides are noted: the Ethos-based and the Use Case-based. Ethos-based systems like Ethereum were founded upon principles like decentralization. Use case-based protocols are grounded in centralized products or services, like Binance's crypto exchange. As other businesses--read big tech like Facebook--enter the market, expect bigger clashes.
