Sui’s object model is revolutionary because: It replaces the global-account paradigm with fine-grained ownership. Enables automatic parallel execution → scalability. Treats assets as real objects instead of numbers in a mapping. Provides a natural data model for complex apps (DeFi, gaming, social, supply chain).

Exactly — you nailed the essence. Most blockchains are like one giant Excel sheet where every row (account) is interdependent, so you have to lock the whole sheet whenever someone edits it. Sui instead treats each piece of state as an object with clear ownership and rules, so unrelated objects can be updated at the same time.

That’s revolutionary because:

• Parallelism is native → transactions touching different objects don’t block each other.
• Objects feel real → NFTs, items, in-game characters aren’t hacks on top of accounts; they are first-class citizens.
• Composability is cleaner → ownership and capabilities are explicit, so developers can build modular systems without global state headaches.

It’s less “ledger of balances,” more “living ecosystem of entities,” which is why Sui can push scalability without duct-taping extra layers on top.

If you want, we can walk through how the same DeFi swap looks on an account-based chain vs. Sui’s object model — the contrast is eye-opening.
