Optimism is a Layer 2 solution based on Ethereum that provides fast, stable, scalable and low-cost blockchain services. By running on Layer 1 of the Ethereum main chain, it helps alleviate network congestion, thereby reducing Transaction costs and processing time. Hyperchain is a multi-chain network structure based on Layer 2 technology that solves the horizontal scalability challenges of traditional blockchains. By treating each chain as an interchangeable computing resource, the commercialization of blockchains allows Developers to build cross-chain applications without increasing systemic risks, sharing not only security and communication layers but also an open-source technology stack. This design allows developers to focus more on building applications on the entire super chain, without having to worry about the specific technical details of individual chains.
