The OP token, distributed through several airdrop rounds, assists in governing Optimism Collective, the decentralized governance structure for the layer 2 blockchain. The structure is a bicameral governance system composed of the Token House and Citizens’ House to “balance short-term incentives” with longer-term goals, according to its working constitution.

Optimism Collective’s Token House, composed of all holders of OP, can vote on technical decisions and software upgrades to the layer 2 blockchain.
