5 · One Resource Market
🚧 Draft (core-idea sketch). Part A · Core Ideas. The first place the primitives combine.
The problem. A decentralized system seems to need three separate markets — storage, bandwidth, compute — each with its own protocol, pricing, and incentives, that must somehow interoperate. That's three hard designs and three integration problems.
The core idea. They are one operation: MATERIALIZE(value, spacetime-region) — make a value available at a place and time. It has three elementary edges:
Any request is satisfied by a min-cost DAG over these edges, and the same value can be produced many ways — "fetch a cached copy vs. recompute it" is just route choice in one graph. So caching = replication = memoization = one threshold rule. disp is the verifiable value algebra that lets a buyer trustlessly mix fetched and computed sub-results; prices act as the system's shared prediction-error signal (predict demand well → pre-position → get paid).
Leans on: identity (1), routing (4), substrate (3), money (6). Enables: the first real paid economic loop in the network.
⚠️ Where it's thin. The unification is abstraction-level: the three edge costs differ by orders of magnitude and by risk type, so three real cost models are still owed. The clean price↔incentive alignment assumes price-taking and convex costs — lumpy storage commitments and relays with market power break it. Part B.
