Arbitrum vs Tezos

Arbitrum One and Nova are optimistic rollups using Nitro fraud proofs that compress transactions into calldata submitted to Ethereum. The Orbit toolkit lets projects deploy their own Arbitrum Orbit chains with configurable permissions. ARB token governance manages the 3 000‑plus validator whitelist and a 1 billion‑dollar ecosystem grant fund.

Tezos is a self‑amending Proof‑of‑Stake Layer‑1 that supports on‑chain governance, letting token holders adopt protocol upgrades without hard forks. Its latest ‘Mumbai’ upgrade activated Smart Rollups, allowing scalable L2s written in Rust and Wasm to inherit Tezos security. Tezos processes ~1 million contract calls daily and is popular for compliant tokenisation of securities in Europe.
