What is Optimism Ethereum Layer 2?
Optimism is a Layer 2 scaling solution for Ethereum. Optimism L2 uses Optimistic Virtual Machine (OVM), an innovative rollup technology that allows for cheaper and faster transactions while maintaining all the key security properties of Ethereum. Optimism was founded in 2017 and is backed by leading VC firms such as a16z, Polychain Capital, and Paradigm. As of 2023, Optimism has raised a total of $150 million in funding.
What are the benefits of using Optimism L2?
- Cheaper and faster transactions: Optimism L2 uses Optimistic Virtual Machine (OVM), which allows for cheaper and faster transactions than on Ethereum's mainnet.
- All the key security properties of Ethereum: By using rollups, Optimism L2 preserves all the key security properties of Ethereum, including finality and liveness.
- Increased scalability: With Optimism L2, businesses can scale their applications without sacrificing security or decentralization.
