CORE vs OP Mainnet

Core is an EVM Layer‑1 that merges delegated proof‑of‑stake voting with hash power from Bitcoin miners through the Satoshi Plus consensus. Validators bond CORE and lease BTC hash via a smart‑contract marketplace, aligning incentives between miners and token holders. The chain offers a native bridge to Bitcoin enabling one‑step transfers of cbBTC and supports Solidity smart contracts.

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.
