Call for DAO Member to Control Multi-Sig

Call for DAO Member

我們將在 2030 年，做到「台灣區塊鏈的龍頭社群」，因為「現代社會對區塊鏈有很多誤解，我們希望這個 conf/DAO 能不分職業、種族、性別等等，平等地去普及各類區塊鏈知識」。

1. 定位：與「不知DAO」的高端市場不同，盡可能降低「演講機會、DAO治理」等參與門檻
2. 徵DAO Member：請有興趣的人來管多簽錢包
3. Call for Proposals：Use snapshot, DAOhaus or other tools for goverance?
