Linera is a real-time blockchain infrastructure designed for highly scalable Web3 applications. It introduces microchains—lightweight, user-managed chains operating in parallel within a shared validator set. This architecture enables predictable performance, low latency, and infinite scalability by allowing users to manage their own chains and validators to scale elastically. Linera employs a delegated proof-of-stake consensus mechanism and supports a language-agnostic, multi-chain programming model, facilitating secure and responsive decentralized applications at internet scale
