Optimism's airdrop model is built around incentivizing developers, users, and contributors who align with its long-term vision. It introduces Retroactive Public Goods Funding (RPGF), where builders are rewarded for past work that benefits the ecosystem. Token allocations often go to those creating open-source tools, educational content, or governance proposals. This retroactive approach encourages sustainable, non-speculative contributions. Airdrop rounds are structured to gradually reward deeper participation, not just one-time interactions. By aligning incentives with network health, Optimism fosters a more cooperative, value-driven community.
