Bitcoin vs Flow

Bitcoin is the first decentralized blockchain, secured by proof‑of‑work where miners expend SHA‑256 hash power to find valid blocks every ~10 minutes. The supply is capped at 21 million coins, with inflation halving roughly every four years—the most recent halving occurred on 20 April 2024. Upgrades like SegWit and Taproot have enabled second‑layer protocols such as the Lightning Network and emerging covenants via OP_CTV debates.

Flow features a multi‑role architecture—collection, consensus, execution and verification nodes—that splits tasks for high throughput while keeping deterministic execution. Cadence, its resource‑oriented language, powers popular NFT projects like NBA Top Shot and Gaia marketplace. The 2024 ‘Spork’ upgrade introduced FCL walletless onboarding and bridged USDC from Ethereum to boost DeFi liquidity.
