OP Mainnet Aims to Reduce Ethereum Congestion with Layer 2 Scaling

OP Mainnet is an Ethereum-compatible Layer 2 blockchain that extends the capacity of the Ethereum network. It's designed to move transaction execution off-chain while relying on Ethereum for settlement and data availability.

The platform uses optimistic rollup technology, which assumes that state proposals are correct unless someone successfully challenges them through a fault proof system.

OP Mainnet is EVM-compatible, allowing developers to deploy Solidity smart contracts and use familiar Ethereum tools with relatively few code changes.
