Last week, I wanted to experience a compliant on-chain U.S. Treasury project. However, just getting through the KYC certification, submitting proof of address and source of assets, I was bounced back three times by the backend, taking a whole two days.

At that moment, I really felt a sense of disconnection: we in this circle shout about decentralization and protecting privacy every day, but once it involves real money in the real world, don’t we still have to obediently hand over our passports and expose our personal information to unknown centralized platforms? What if one day the platform's database gets hacked?

This deadlock of "needing compliance while also wanting privacy" is not only a pain point for ordinary people, but also the core reason why those trillion-dollar “old money” folks on Wall Street are hesitant to play on-chain at scale.

This is also why YZi Labs is willing to spend heavily to lead the investment in Sign Protocol. Many people still think that @SignOfficial is just a tool for issuing “on-chain activity participation certificates,” which is a huge underestimate of it. In the grand chess game of RWA, Sign is actually the most critical “trust firewall” between traditional finance and DeFi.

Let’s break down this logic:
DeFi's smart contracts are permissionless; anyone can play; but institutional money is regulated and must know who the customer is. How do we stitch these two together?

Through Sign, you only need to do a one-time identity and asset verification at a trusted off-chain institution. Once verified, Sign will generate an immutable “certificate” for you on-chain.

Here comes the best part: this on-chain certificate does not contain your real name, photo, or passport number at all. It's like a blurred pass that only broadcasts a status to the entire network—“This address is compliant and has the qualification of 100,000 U.”

When you want to borrow or purchase RWA assets, downstream DeFi protocols only recognize this Sign certificate, allowing you to proceed without needing to know your real identity. #Sign地缘政治基建

Did you notice? Sign has thoroughly separated “compliance verification” from “privacy data.”
Without such a foundational protocol, RWA will always be just a self-indulgence for small funds, and cannot support the trillion-scale of traditional finance.
