Emerging Alternative Game position: Modify
Prototype: Optimism RetroPGF
Funds public goods only after impact is demonstrated, with reviewers rewarding completed contributions rather than funding proposals upfront.

Architecture
- Game position
- Modifies the game at the public-goods allocation layer
- Value-signal richness
- Single matching-fund unit; allocation follows demonstrated impact
- Accumulation regime
- Accumulation by recipients; mechanism rewards proven contribution
Medium-of-Exchange Properties
- Divisibility
- The funding unit is finely divisible, matching the underlying token (e.g. OP) it is denominated in.
- Uniformity (Fungibility)
- Fungible — funding allocations are interchangeable units, differentiated only by amount, not identity.
- Durability
- Not applicable — a one-time distribution tied to demonstrated past impact, not a durable store of value.
- Portability
- Not applicable — the mechanism allocates an existing token (e.g. OP) after the fact, it doesn't create a portable unit.
- Acceptability
- Not applicable — it's a distribution mechanism, not something counterparties accept in trade.
Operation
- Coordination / discovery
- Deliberative ex-post evaluation of demonstrated impact
- Governance & issuance
- Sponsor or DAO allocates; evaluation by selected reviewers
- Scale & federation
- Network-scale typically; federation underdeveloped
Anthropological assumptions
- Default ethical orientation
- Smithian-Rousseauian; individual raters exercising a communal capacity for retrospective impact judgment.
- Accumulative drive
- Drive partially redirected; reward follows demonstrated value
- Status / recognition
- Partially separated; recognition through retrospective evaluation
- Time preference
- Long — retroactive public-goods funding reads as institutional-stability-adjacent, rewarding sustained contribution to shared infrastructure.
In Practice
- Track record
-
Optimism's RetroPGF has run multiple funding rounds since 2022 , distributing OP tokens to public-goods projects based on demonstrated impact — a real, well-documented, growing program. - Governance requirements
- Requires a funding body (here, the Optimism Collective) with a badgeholder or similar review process to evaluate impact and allocate funds; recipients need no special structure.
- Resource requirements
- An existing token/treasury to fund rounds from; recipients need only a wallet to receive funds.
Organizational types interconnected with this mechanism
- DAO (Decentralized Autonomous Organization)
Several ecosystem DAOs use retroactive funding to pay for public-goods impact after it is visible, with Optimism's multi-round RetroPGF program the best known.
