Avalanche vs Bitcoin

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.

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.
