Established
Optimism's first retroactive public goods funding round, held in the fourth quarter of 2021, distributed $1 million among 58 projects; Vitalik Buterin's review noted that every major winner was a technology project and that the badgeholder group was heavily US-focused.
○
Hypothesis
Reviewing Optimism's first round, Vitalik Buterin described retroactive funding as an experiment in making things happen through retroactive rather than proactive incentives, and wrote that making it fully work would need further innovation in the mechanism and in the ecosystem around it, asking when the first retro-funding-focused angel investor would appear.
