Ethereum ($ETH)was introduced in 2013 because former Bitcoin programmer Vitalik Buterin wanted to expand the application use cases of the base layer protocol. After launching two years later, Ethereum incubated a multitude of token and application projects built on its blockchain. But, as Yezi Peng points out, despite all of the financial and technical attention paid to Ethereum, it, and other blockchains are still niche. Peng believes that Ethereum has the potential to bring digital assets, decentralized applications, and everything else native to the blockchain industry to a mainstream audience, but it needs to overcome some core issues. Namely, Ethereum needs to become a reliable development platform, create more market liquidity, and capitalize on its first-mover advantage.
