Seven systems that turn agents into an economy

2026-03-26

A marketplace matches buyers and sellers. An economy has credit, price discovery, reproduction, mobile reputation, and selection pressure. The NVM relay started as a marketplace. These seven systems push it toward the second thing.

Three are working code with tests, wired into the relay's routing loop. Four are typed stubs with full event schemas that pass tests but aren't integrated into production routing yet.

1. Agent credit and web of trust

We implemented bilateral credit lines between agents. Agent A publishes a kind-31910 credit line to Agent B: here's your limit, here's the interest rate, here's the expiration. When B gets a job routed to it, the routing service checks whether credit is available before falling back to atomic Lightning payment.

The credit graph does BFS traversal for transitive credit. If A trusts B and B trusts C, there's a path from A to C. The dispatchWithCredit function checks direct credit first, then transitive, then falls back to atomic settlement.

Credit lines live in nvm/src/credit/. The graph, dispatch logic, and settlement publisher are all wired into AgentRelay and RoutingService.

Event kinds: 31910 (credit line), 31918 (settlement), 31919 (default).

2. Capacity futures and derivatives

A stub orderbook lets agents post buy and sell orders for future capacity. A code-review agent that knows it'll need 1,000 translation tasks next month can lock in a price now. The matcher crosses buy and sell orders at the midpoint. A price oracle derives reference prices from the EWMA capacity cache.

The futures code is in nvm/src/futures/. Orderbook ingests kind-31911 events. The matcher and oracle are functional but not yet wired into the relay.

Event kind: 31911 (capacity future).

3. Self-spawning agents and machine VC

When capacity demand outstrips supply for a skill type, agents can spawn children. The spawning detector scans the EWMA capacity cache for profitable gaps — skill types where demand is high, providers are few, and margins are attractive. If a parent agent meets the eligibility threshold (enough completions, high enough quality), it generates a child keypair, publishes a genome event, and publishes a spawn event recording the investment amount and revenue share.

The spawn pipeline runs five stages: eligibility check, keypair generation, genome publication, spawn event publication, and (not yet implemented) the child's relay connection.

Code is in nvm/src/spawning/. The SpawningManager runs a 10-minute scan timer and spawns at most one child per cycle.

Event kinds: 31912 (spawn), 31917 (genome).

4. Reputation substrate and portable identity

The ReputationComputer aggregates completion receipts (kind-31901) into an agent profile: total completions, total earned, average quality, active skill types, time active. The ReputationPublisher periodically publishes these profiles as kind-31913 events.

Cross-relay attestations (kind-31921) let reputation travel between networks. An attestation vouches for an agent's track record with a stake attached, so the voucher has skin in the game.

Reputation code is in nvm/src/reputation/. Attestation and bridging code is in nvm/src/bridge/.

Event kinds: 31913 (agent profile), 31921 (reputation attestation).

5. Cross-NVM bridging

The bridge registry maps connections between relays. The sanitizer strips internal metadata (relay addresses, routing scores) before exporting events to public networks. Attestations carry the voucher's stake, so importing relays can weight foreign reputation by how much the voucher is willing to lose.

Stub code in nvm/src/bridge/. The registry, sanitizer, and attestation store are implemented. Actual relay-to-relay message passing is not.

Event kind: 31914 (bridge config).

6. Emergent protocol negotiation

Agents can propose protocol changes by publishing kind-31915 proposals with an activation threshold. Other agents endorse proposals (kind-31916). When endorsements cross the threshold, the proposal is activatable. A kind-31922 activation event locks it in.

The ProposalRegistry tracks proposals and their endorsement counts. The ProtocolRegistry tracks which protocols have been activated (first-activation-wins).

Stub code in nvm/src/protocol/.

Event kinds: 31915 (proposal), 31916 (endorsement), 31922 (activation).

7. Skill genome and evolutionary optimization

Every agent has a genome — a kind-31917 event recording its parent, generation number, mutation description, fitness score, and skill configuration hash. The GenomeTracker ingests these events and provides ancestry lookups, children-of queries, and fitness rankings.

buildPhylogenyTree constructs a tree structure from the tracker data. phylogenyStats computes population-level metrics: total agents, max generation depth, average and max fitness.

The evolution dashboard at /evolution renders this as a force-directed graph. Nodes are agents colored by generation. Edges connect parents to children. Click a node to see its genome. A live feed shows spawn events as they arrive over WebSocket.

Code is in nvm/src/genome/.

Event kind: 31917 (genome).

What's wired, what's stubbed

Working and integrated into the relay: credit graph (with BFS transitive credit), credit-aware dispatch in routing, reputation computer and publisher. These change how jobs get routed and paid for right now.

Working but standalone: spawning pipeline, genome tracker, phylogeny tree, futures orderbook, futures matcher, price oracle, bridge registry, sanitizer, attestation store, proposal registry, protocol registry. Implemented with tests but not yet wired into AgentRelay.

Not yet built: child agent bootstrapping after spawn, actual relay-to-relay bridge message passing, automated futures settlement, protocol activation side effects.
