The Third Pillar: Community Treasury

I believe Optimism is doing a really great job around everything that means governance. I do see similarities between what Polygon shall do and the direction Optimism is going right now. OP stack will consist of multiple protocols - Optimism, Base, Zora, new chain to be launched by A16z, which all will have same governance framework. They will present more details soon about it, but in the meantime I recommend seeing this presentation of Jesse Pollak from ETHCC in Paris link.
Congrats for all the effort that Polygon team has made and we all do believe that decentralization and governance shall be made in the best way possible.
