Cardano vs Optimism FAQ

What is Cardano?
Cardano (ADA) is a proof-of-stake blockchain launched in 2017, designed by IOHK with a research-driven approach. Its Ouroboros consensus was peer-reviewed before mainnet, and it has pursued phased upgrades (Byron, Shelley, Goguen, Basho, Voltaire).
How does Cardano differ from Ethereum?
Cardano uses an eUTXO model (extended unspent transaction output) rather than Ethereum's account model. It ships upgrades via hard forks coordinated through Haskell-based Plutus smart contracts. Throughput historically lagged peers, though Hydra L2 rollouts aim to close that.
What is Optimism?
Optimism is an optimistic rollup L2 on Ethereum, launched mainnet 2021 by OP Labs. The broader project is the Optimism Collective — a bicameral governance with the Token House (OP holders) and Citizens' House (soulbound voting for Retroactive Public Goods Funding).
What is the OP Stack?
Open-source codebase for launching optimistic rollups. Base (Coinbase), World Chain, Zora, Mode, and dozens of others are OP Stack chains. Together they form the "Superchain" — shared sequencing infrastructure, bridging, and a common governance layer. It is the dominant rollup framework by chain count.
How do Cardano and Optimism compare?
Cardano (ADA): Research-driven Layer 1. Peer-reviewed Ouroboros consensus, eUTXO model. Launched 2017, runs Ouroboros Proof-of-Stake. Optimism (OP): OP Stack Superchain (Base, World Chain, Zora). Retroactive Public Goods Funding. Launched 2021, runs Optimistic Rollup (Ethereum L2).
