About WTF: the Power of Asking

A modern resurrection of the Greek Pnyx (/nɪks/): a supportive space for open, inclusive, informed, and thoughtful exchanges of ideas, for the practice of the ancient art of asking the right questions to move beyond hype and arrive at knowledge.

"A DeFi Billboard" Harberger Taxes Social Experiment (Coming Soon)

This is the only place you’ll see logos, REALLY LOUD LOGOS. We are creating “A DeFi Billboard” specifically to take shilling off the serious discussions.
“A DeFi Billboard” is both physical and virtual: We will conduct a continuous auction for 10 display slots on with a Harberger Tax mechanism. In a Harberger Taxation model, the buyer/advertiser sets the price, then the next buyer accepts the price, and pays a tax until he/she is bought out by another buyer, or he stops paying taxes. The tax goes to the event’s ENS address: defiwtf.eth. The proceeds will go into funding the event and funding research that comes out of the event.
Auction starts Oct 2, 2019
Participating in the continuous auction may result in:
Logo showing on a virtual DeFi Billboard on DeFi.WTF website.
Logo showing on a physical retro-style neon billboard will also be presented at the event venue based on a snapshot taken of the on-chain auction (snapshot time to be announced).
"A DeFi Billboard" is inspired by previous experiments on Harberger Taxes:
"This Artwork Is Always On Sale (TAIAOS)" by Simon de la Rouviere;
Harberger Ads a 2018 ETHSanFrancisco winning hack;
一块广告牌 An Advertisement Board by China's BES Studio;
一块广告牌-橙皮书分叉版 An Advertisement Board- OrangePaper Edition by Chinese media OrangePaper.
We need more help with design and implementation of the Harberger Taxes social experiment! (DM @CarboClanC on GitHub or Telegram @TinaZhen)

Pop-up Collective – Dissolves after 21 Days

If you are a thinker/creative/hacker, join our pop-up collective of volunteers in preparation of that will exist for 21 days then dissolve. The collective will determine the spending of the donations and “A DeFi Billboard” proceeds, and publish the financials once the collective dissolves.
The collective will determine which research streams gets the remaining balance. Prior to dissolving, the collective also decides whether to turn into a loosely-organized community or a more institutionalized DAO with clear governing mechanism.
