Polkadot vs Optimism FAQ
- What is Polkadot?
- Polkadot (DOT) is a sharded multi-chain network launched in 2020 by Gavin Wood (Ethereum co-founder, Parity CEO). Its Relay Chain provides shared security for connected parachains, each of which can specialise its own logic and governance.
- What are Polkadot parachains?
- Parachains are application-specific L1-like chains that lease a slot on Polkadot for a fixed term by bonding DOT. Examples: Acala (DeFi), Moonbeam (EVM compatibility), Hydration (liquidity). Recent Polkadot 2.0 moves toward "coretime" — renting blockspace per block.
- 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.
