Sui co-founder Evan Chen makes a simple argument. Whether cryptocurrencies are ready to hear that is another question. He has seen these systems from the inside. So when he says Ethereum and Solana are built on flawed foundations, it lands differently than normal founder noise.
It all starts with a spreadsheet
His argument begins with a surprising simplicity. At the heart of Ethereum is a ledger, a giant digital spreadsheet. Address A has 10 USDC. Address B has 5. Money moves and numbers change. That’s really all. It works fine when moving identical tokens between wallets. It worked fine for 10 years.
The problem, Chen argues, is that the real world doesn’t work like a spreadsheet.
A house that changes everything
Let’s think about home. On the day you buy it, it will look like every other house on that street, have the same value, and have the same construction. However, after 10 years, things are completely different. It was renovated. The neighborhood has changed. There was development going on next door. Houses now have a history, a specific identity, and a relationship with their surroundings. It cannot be exchanged for anything else.
The Ethereum ledger is not designed for such assets. It was made for uniform, static, identical coins. More subtle things are added as an afterthought and it shows.
static web issues
For Ethereum bulls, the similarities to the internet are jarring. Early websites were static pages, digital brochures that could display information but couldn’t remember, respond to, or change users. Companies that have tried to force dynamic experiences onto their static architectures have largely failed. Google and Amazon, the companies that built complexity from the ground up, won decisively.
Chen believes that cryptocurrencies are approaching the same tipping point.
What Sui actually claims to solve
Sui treats every asset as a separate object with its own identity and history. This is something that can evolve through interaction, rather than just sitting in a balance column. Less spreadsheets, more living records.
Whether that architectural difference translates into real-world advantages remains entirely unknown. Ethereum has a decade of battle-tested security and is worth trillions of dollars that will never go away. That trust cannot be easily given up.
Sui is newer, smaller and has not yet proven its scale. These are actual limitations, not points of contention.
unpleasant question
Chen’s argument is not that Ethereum is broken. That is, Ethereum was designed with a simpler problem in mind than the one that cryptocurrencies actually face today. This argument is difficult to dismiss, and even more difficult to answer.
He might be early. He might be right. In technology, these two have a long history of being one and the same.
