Avalanche vs Cardano

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.

Cardano uses the Ouroboros Proof‑of‑Stake protocol and an Extended‑UTxO ledger that enables deterministic smart contracts in Plutus and Aiken. Its ‘Basho’ scaling era introduced Hydra Head sidechains capable of 1000 TPS per head, and Mithril light‑client proofs for mobile wallets. Over 1 500 stake pools secure the network and participate in on‑chain treasury governance.
