@xmbl/storage-compute

The storage and compute market: nodes sell disk and CPU, and the runtime that executes untrusted, third-party WASM for pay is hardened to enforce its limits rather than assert them.

npm install @xmbl/storage-compute

What it owns

| Export | What it is | |---|---| | ComputeRuntime | The sandbox. Guest code runs on a dedicated Worker thread the host can terminate, so a synchronous loop in the guest cannot wedge the event loop — a Promise.race "timeout" on the host thread can never fire against one. Memory is bounded and the import surface is policy, not default. | | ComputeNode | A node offering compute to the market. | | StorageShard, StorageNode, computeProbeProof | Sharded storage and the proof a node returns when probed. | | AvailabilityTester | Availability probing — does the node that was paid still hold the data? | | MarketPricing | Pricing for both resources. |

The three properties the runtime enforces

1. Wall-clock termination — the guest runs where it can be killed.
2. A memory bound — set at instantiation, not hoped for.
3. An import policy — the guest reaches only what it was granted.

compute.test.mjs exercises these against guests that try to break each one.
