Avalanche vs Flow

Avalanche implements Snowman consensus on its C‑Chain (EVM) and runs a multi‑chain architecture with X‑Chain (UTXO) and P‑Chain (staking). Custom subnets allow projects like DeFi Kingdoms and Intain RWA to spin up their own validator sets with whitelisted tokens. The 2025 Banff hard fork added elastic subnets with dynamic validator staking for improved security sharing.

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.
