Linera presents an innovative elastic multi-chain protocol designed to overcome Web3's scalability challenges by introducing unlimited parallel microchains for users and applications, all secured by a single delegated Proof-of-Stake validator set, enabling predictable low-latency performance and seamless cross-chain communication through asynchronous messaging and commutative inboxes. This architecture allows developers to build in Rust/Wasm and deploy across chains, offering users gas-free experiences on their own microchains and achieving potential throughput exceeding 100K TPS, aiming to create Web3 applications with the speed and feel of Web2.
