A market where each listing is associated with a Gitcoin grant or other public goods project (instead of a Twitter account) could:
Facilitate discovery of worthwhile public goods projects
Create a separate income stream for projects that is not based on sheer generosity
Expand the pool of public goods contributors to include speculators and profit-seekers
Pay out slowly instead of all at once, allowing market participants to decide over time which projects are meeting their goals
The challenge is this:
Ideamarkets are permanent, so when a Grant project gets finished, abandoned, or VC funding, people will lose money as that Grant's market dumps.
Therefore, public goods funding via Ideamarket requires a slight tweak: closeable markets
Market "auto-closes" in 1 year by default.
When the market closes, no more buys are accepted, and all DAI in the bonding curve gets distributed back to buyers, in proportion to their upvote holdings.
