Near vs OP Mainnet

NEAR Protocol employs Nightshade sharding where each block contains chunks from multiple shards, and Doomslug consensus gives 1‑second near‑finality. The JavaScript SDK and Contract Aurora EVM make onboarding Web2 developers easier. In 2024 NEAR launched a chain‑signature wallet standard that leverages passkeys for seedless login.

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.
