In principle, even though various implementation methods carry risks, the concept of personality proof remains extremely valuable. At the same time, a world completely devoid of any personality proof still cannot avoid risks: a world without personality proof seems more likely to be dominated by centralized identity solutions, currency, small closed communities, or some combination of the three.

For Ethereum to truly become mainstream, these three transformations are essential.

The social consensus of the blockchain community is a fragile thing, and we should maintain the minimalism of blockchain to avoid overloading Ethereum's consensus.

ZK-EVM will become the third client of Ethereum and is expected to promote the creation of an open multi-client ZK-EVM ecosystem.

The two key issues for safely using multi-signature wallets and social recovery wallets are: who you choose as guardians, and what instructions you give them?

User experience is a key reason why many Ethereum users (especially those in the Southern Hemisphere) often choose centralized solutions over on-chain decentralized alternatives.

Vitalik Buterin believes that stealth addresses can be quickly implemented and can significantly enhance the privacy of Ethereum users, but they may also introduce usability issues such as difficulties in social wallet recovery. These issues can be resolved in the long run, but the stealth address ecosystem does seem to heavily rely on zero-knowledge proofs.

For anti-establishment individuals, which paths forward are meaningful?

Money, DeFi, identity systems, DAO, and hybrid applications.

This article will delve into the historical attempts to bring trading closer to a trustless model, the limitations of these technologies, and some updated and more powerful ideas relying on ZK-SNARKs and other advanced technologies.
