Avalanche vs Starknet

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.

Starknet is a STARK‑based validity rollup where smart contracts are written in Cairo and executed off‑chain, with succinct proofs verified on Ethereum. The 2024 Madara sequencer supports parallel execution, and the ‘Quantum Leap’ upgrade reduced L1 calldata by 30 %. STRK token launched in February 2025, enabling slot auctions for sequencer decentralization roadmap.
