Main repository for the Linera protocol
Linera is a blockchain protocol built in Rust that takes an unusual approach: instead of one global chain, every user gets their own 'microchain' that runs in parallel. The idea is to eliminate transaction ordering bottlenecks by making most operations chain-local. It's aimed at developers who want to build Web3 apps without the latency and throughput constraints of traditional L1s.
The microchain model is the genuinely interesting part — cross-chain messaging is asynchronous and explicit, which forces application developers to reason about concurrency honestly instead of pretending everything is atomic. The linera-views abstraction (mapping Rust data structures onto a key-value store) is well-thought-out and makes state management portable across storage backends. The Wasm execution model means app contracts are isolated and can run in-browser, which is a meaningful architecture win over EVM. The example applications (AMM, fungible tokens, crowd-funding) are real enough to actually learn from, not toy counters.
The getting-started experience requires compiling the entire protocol from source before you can do anything — no pre-built binaries in the README path, just a cargo build that will take 20+ minutes on first run. The microchain model also shifts coordination complexity onto the application developer: anything that needs global ordering (a shared DEX orderbook, a global leaderboard) becomes your problem to solve with cross-chain messages, which is non-trivial. The Ethereum bridge is marked experimental and the EVM integration story is still rough — if you're hoping to port Solidity contracts directly, you're not there yet. The validator/operator setup is significantly under-documented compared to the application developer path.
