Wu said that Vitalik Buterin pointed out that protocol simplicity is at the core of trustlessness, self-sovereignty, and long-term security. Even with high decentralization, if the code is bloated and dependencies are complex, users will still be forced to trust a few experts, which weakens sustainability. He called for Ethereum to introduce a clear “simplification/garbage collection” mechanism to reduce unnecessary features and complex dependencies, strengthen invariants, and delegate less frequently used but complex features to the contract layer to prevent ongoing protocol expansion and support long-term stable development.
