Polkadot vs USD Coin 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 USDC?
- USDC (USD Coin) is a dollar-pegged stablecoin issued by Circle. Each USDC is backed 1:1 by USD-denominated reserves (cash and short-duration US Treasuries), attested monthly by a major accounting firm and held at regulated US banks.
- Is USDC safe?
- USDC has maintained its peg since launch in 2018, with the notable exception of a brief de-peg in March 2023 during the Silicon Valley Bank collapse, where Circle had exposure. Reserves are now diversified across multiple banks and short-dated Treasuries.
