# llimphi-wasm-net

P2P transport for the distribution of Tier 3 WASM apps.

A minimal stream protocol over `BrahmanNet` (card-net, the shared
libp2p TCP+Noise+Yamux+Kad mesh):

- `serve_blobs` brings up a responder that, for each incoming stream on
  `/llimphi-wasm/blob/1.0.0`, answers a `Get{hash}` by serving the bytecode from
  a `DiskStore` (or `NotFound`).
- `fetch_blob` opens a stream to a provider and asks for a blob by hash.
- `fetch_blob_dht` discovers providers through the DHT and tries each one.
- `RemoteSource` wraps the above as a synchronous `BlobSource`, so
  `llimphi-wasm-dist`'s `resolve→verify` chain runs over the network without
  knowing about the transport.

The framing copies minga's (`[u32 LE len][postcard]`). Integrity is NOT trusted to
the network: `llimphi-wasm-dist::resolve` rehashes the received blob against the
requested hash, so a malicious provider cannot slip in a different wasm.
