Optimism

Optimism is an optimistic rollup for Ethereum whose broader project is the OP Stack — a shared, open codebase other networks deploy to form a Superchain of chains with common standards and shared sequencing revenue. OP is a governance token; gas is paid in ETH.

The OP Stack turned a rollup into a template

Rather than operating one chain, Optimism published its stack for others to run, and several major networks are built on it. Shared code means shared upgrades and interoperability by default, and it turns competitors into a coalition — a strategic choice that distinguishes it from rollups that keep their implementation proprietary.

Retroactive public goods funding

The project allocates revenue to work already done rather than to promises, on the argument that judging completed contributions is far easier than predicting which proposals will succeed. It is one of the few genuinely novel funding experiments in the industry, and it has distributed meaningful sums to infrastructure that had no direct business model.

Two houses in governance

Governance is split between a Token House voting with OP and a Citizens' House whose membership is not purchased. Separating decisions that suit token-weighted voting from those it distorts — funding public goods being the obvious case — is a direct response to the plutocracy problem in DAO design.

The same rollup mechanics, the same open item

Data is posted to Ethereum and results are assumed valid unless challenged during a dispute window. As with every optimistic rollup, sequencing remains centralised for now, and users retain a path to force transaction inclusion through Ethereum if the sequencer misbehaves.

What OP represents

OP votes on protocol parameters, treasury allocation and Superchain policy. It is not consumed by usage. Its case depends on the governance and treasury value of a growing network of chains rather than on transaction demand for the token itself.
