Bitcoin vs Polkadot FAQ
- What is Bitcoin?
- Bitcoin (BTC) is the first decentralised cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. It uses a proof-of-work consensus to settle transactions without a central issuer, and its supply is capped at 21 million coins.
- Who controls Bitcoin?
- No single entity controls Bitcoin. A distributed network of miners secures the ledger, node operators enforce the rules, and developers propose protocol changes through Bitcoin Improvement Proposals (BIPs) that must reach rough consensus to ship.
- 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.
