Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building Numax I had a great time! I love Numax and I love software. Thanks to anyone who'll spend a bit of their time even just to open the repo and take a look!

Could you build this?
No Numax is a distributed systems runtime in Rust integrating a WASM sandbox, embedded key-value storage, and CRDTs over a peer-to-peer gossip network.
What it would actually take: The system requires Rust, Wasmtime/Wasmer runtime embedding, a storage engine (like RocksDB or Sled), and custom implementations of gossip protocols (like PlumTree or SWIM) combined with state-based or operation-based CRDTs. The hard challenge is ensuring deterministic WASM execution, formal convergence guarantees in asynchronous networks under partition, and memory safety at low-level runtime boundaries.
