An overview of the Layer 2 scaling solution OP Chain, the OP Stack software and the wider Optimism ecosystem.

In the realm of blockchain technology, scalability remains a significant challenge. This is where OP Mainnet, a Layer 2 scaling solution for Ethereum, comes into play. It's specifically designed to provide faster transactions at a fraction of the cost, helping to address Ethereum's scalability issues.What is the OP Mainnet?

OP Mainnet is a Layer 2 network that operates on top of Ethereum's architecture, acting as a minimal extension of the main Ethereum layer. It allows developers and crypto users to enjoy quick transactions at low fees while maintaining the security of Ethereum's architecture. Optimism's rollup technology bundles multiple transactions from Ethereum’s Layer 1 into a single transaction, effectively distributing the transaction fee among all users involved in the transactions. The rollup is executed on Optimism’s Layer 2 network OP Mainnet, while the transaction data is posted to Ethereum’s Layer 1 for processing.
