OP Mainnet vs Vaulta

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.

Vaulta is a Layer-1 chain built as the operating system for Web3 banking. It combines a high-performance, deterministic-finality blockchain with modules for wealth management, consumer payments, portfolio investment, and crypto-native insurance. Fully EVM-compatible, Vaulta supports Bitcoin integration via ExSat, cross-chain transfers through IBC, and a staking-backed stable financial infrastructure for institutions and individuals.
