Cardano vs Polkadot 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 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.
How do Cardano and Polkadot compare?
Cardano (ADA): Research-driven Layer 1. Peer-reviewed Ouroboros consensus, eUTXO model. Launched 2017, runs Ouroboros Proof-of-Stake. Polkadot (DOT): Sharded multi-chain network. Parachains share relay-chain security. Launched 2020, runs Nominated Proof-of-Stake.
