Ethereum vs Optimism FAQ
- What is Ethereum?
- Ethereum (ETH) is a programmable blockchain launched in 2015. It lets developers deploy smart contracts — self-executing programs that power DeFi, NFTs, DAOs, and most on-chain applications. ETH is the native asset used to pay for transactions ("gas").
- How is Ethereum different from Bitcoin?
- Bitcoin is optimised for being sound money and a settlement layer; Ethereum is optimised for programmability. Ethereum switched to proof-of-stake in 2022 (The Merge), so it has no miners — validators stake ETH to secure the network instead.
- 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 Ethereum and Optimism compare?
- Ethereum (ETH): Programmable Layer 1. Smart contracts, DeFi, NFTs. Proof-of-stake since 2022. Launched 2015, runs Proof-of-Stake. Optimism (OP): OP Stack Superchain (Base, World Chain, Zora). Retroactive Public Goods Funding. Launched 2021, runs Optimistic Rollup (Ethereum L2).
