ICP vs OP Mainnet

The Internet Computer (ICP) is a Layer‑1 that runs WebAssembly ‘canisters’ directly on chain, with sub‑second query calls and 2‑second update finality. Boundary nodes translate HTTP requests into signed chain queries, enabling dApps to serve web front‑ends without traditional servers. ICP’s reverse GAS model bills cycles in stable dollar terms, shielding developers from token volatility.

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.
