# Zainan Victor Zhou Zainan Victor Zhou is a builder working at the intersection of web standards, blockchain, and everyday utility apps. He is the founder and CEO of Namefi (by D3Serve Labs), a startup tokenizing DNS domain names on Ethereum as NFTs and bringing them into DeFi. Before that, he was the Tech Lead for smart contract architecture at Google Labs' blockchain team, and his earlier background spans Microsoft Research, Johns Hopkins University, and Tsinghua University. Beyond founding, he is a long-time contributor to the Ethereum ecosystem as an EIP Editor and author, with authored proposals including EIP-5453 (Endorsement), EIP-5679 (Mint/Burn), and EIP-5750 (Extensibility), plus reviews across voting interfaces, jurisdiction and enforcement standards, and anti-poisoning address formats. What makes him interesting as an indie builder is the range of his side projects, each solving a concrete problem: **3-Line Calendar**, a minimal app that shows your next three events across Apple Watch, iPhone, iPad, and Mac; **Pretty Safe**, which prevents address-poisoning attacks on crypto wallets; **WikiLoop DoubleCheck**, an AI-assisted tool for fighting vandalism on Wikipedia; and **Haoshiyou**, a housing community platform for Chinese-speaking renters. His personal site ([zzn.im](https://zzn.im)) is itself a small lesson in builder craft — the footer displays the site's version number, live git commit hash, and deploy timestamp, with the whole site open-sourced on GitHub. His broader mission, laid out in his "Manifesto of Digital Trust," is that digitizing trust will unlock a new era of productivity the way digitizing information did before it. Based in Sunnyvale, CA.
