Optimism (OP) is a layer-2 scaling solution for Ethereum designed to improve transaction speeds and reduce costs. It uses a technology called optimistic rollups to process transactions off-chain and then submit them to the Ethereum network, allowing for greater scalability while maintaining Ethereum's security.

WHAT IS OPTIMISM (OP)?
Optimism is an open-source, Ethereum-compatible layer-2 platform that increases Ethereum’s scalability and transaction throughput. By utilizing optimistic rollups, Optimism processes most transactions off-chain and only periodically submits data to Ethereum, enabling faster and cheaper transactions.

KEY FEATURES

• Optimistic Rollups: Optimism uses optimistic rollups to execute transactions off-chain, significantly reducing fees and improving transaction speeds.

• Ethereum Compatibility: Optimism is fully compatible with existing Ethereum smart contracts, allowing developers to migrate or build dApps easily.

• Scalability: By offloading transaction processing, Optimism increases the capacity of the Ethereum network, handling more transactions per second.

• Low Fees: Transaction costs on Optimism are much lower than on Ethereum, making it ideal for DeFi applications and smaller transactions.

• Security: Optimism inherits Ethereum's security model, ensuring the integrity of transactions processed on the platform.
