Sui co-founder Evan Cheng has a simple argument. Whether crypto is ready to hear it is another matter. He has seen these systems from the inside. So when he says Ethereum and Solana are built on a flawed foundation, it lands differently than the usual founder noise.
It All Starts With a Spreadsheet
His argument begins somewhere disarmingly simple. Ethereum, at its core, is a ledger, a giant digital spreadsheet. Address A has 10 USDC. Address B has five. Money moves, numbers change. That is genuinely all it is. For shifting identical tokens between wallets, it works fine. It has worked fine for a decade.
The problem, Cheng argues, is that the real world does not behave like a spreadsheet.
The House That Changes Everything
Consider a house. On the day you buy it, it looks like every other house on the street, same value, same structure. But ten years later it is completely different. You renovated. The neighbourhood changed. A development went up next door. The house has a history now, a specific identity, relationships with things around it. It is not interchangeable with anything else.
Ethereum’s ledger was never designed for that kind of asset. It was built for coins, uniform, static, identical. Anything more nuanced gets bolted on as an afterthought, and it shows.
The Static Web Problem
The internet parallel is uncomfortable for Ethereum bulls. Early websites were static pages — digital brochures that could display information but couldn’t remember you, respond to you, or change. Companies that tried to force dynamic experiences onto that static architecture mostly failed. The ones that built for complexity from the ground up, Google, Amazon, won decisively.
Cheng believes crypto is approaching that same fork in the road.
What Sui Actually Claims to Solve
Sui treats every asset as an individual object with its own identity and history, something that can evolve through interaction rather than just sit in a balance column. Less spreadsheet, more living record.
Whether that architectural difference translates into real-world dominance remains genuinely open. Ethereum has a decade of battle-tested security behind it and trillions in value that never disappeared. That credibility is not easily dismissed.
Sui is newer, smaller, and still unproven at scale. Those are real limitations, not talking points.
The Uncomfortable Question
Cheng’s argument is not that Ethereum is broken. It is that Ethereum was designed for a simpler version of the problem than the one crypto now actually faces. That is a harder claim to dismiss, and a harder one to answer.
He may be early. He may be right. In technology, those two things have a long history of being exactly the same.
