For decades, phone numbers have been treated as a secure and personal way to identify and communicate with individuals. They feel private, direct, and uniquely tied to a person. In reality, however, phone numbers function less like private credentials and more like persistent identifiers that expose users to tracking, profiling, and exploitation.

As digital communication evolves, it is worth reexamining a fundamental assumption: that a phone number is an acceptable foundation for privacy. It is not.

Why Sovereign Speech Is the First Layer of Digital Freedom

Over the past decade, Ethereum has built something unprecedented: a neutral, persistent digital substrate where value, rules, and coordination mechanisms can exist without centralized ownership. It gives us shared state without a sovereign.

But shared state is not enough.

Before finance, before governance, before markets — there is communication. And if communication is not sovereign, none of the layers built on top of it are stable.

Sanctuary technologies begin there.

In December 2024, Vitalik Buterin published "What I would love to see in a wallet" — a detailed wishlist for the ideal Ethereum wallet. It wasn't just about sending tokens. It was about reimagining how users interact with Web3: seamless cross-chain experiences, robust account security, ZK-wrapped identities, and privacy that actually works.

At Spritz, we've been building exactly this — not just for finance, but for communication.

Just hours ago, Vitalik Buterin declared "The decentralized renaissance is coming" — and called on developers to buidl decentralized. This is exactly what Spritz has been doing.
