Polkadot vs Ethereum 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 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.
- How do Polkadot and Ethereum compare?
- Polkadot (DOT): Sharded multi-chain network. Parachains share relay-chain security. Launched 2020, runs Nominated Proof-of-Stake. Ethereum (ETH): Programmable Layer 1. Smart contracts, DeFi, NFTs. Proof-of-stake since 2022. Launched 2015, runs Proof-of-Stake.
