OP Mainnet vs Tezos

OP Mainnet (Optimism) is an optimistic rollup that batches transactions to Ethereum and relies on fraud proofs submitted during a seven‑day challenge window. The Bedrock upgrade in 2023 cut L1 calldata costs by 40 % and introduced multi‑proof modularity. ‘RetroPGF’ rounds redistribute protocol revenue to public‑goods builders, governed by the OP token‑holder Collective.

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.
