9. End-to-End Commerce Flow

The following sequence illustrates a machine buying a metered physical service from another machine.

Pay → Work → Proof → Settle Sequence showing a machine receiving delegated policy, accepting an offer, paying for measured work, anchoring proof, and settling value.

Figure 2. A complete machine-commerce loop links delegated authority, measured delivery, verifiable evidence, and settlement.

Step 1: Delegation#

The owner or fleet controller assigns the buyer machine a budget and policy. The machine receives permission to buy a defined service from approved counterparties within price and risk limits.

Step 2: Offer#

The seller machine publishes a signed offer containing service type, unit price, measurement method, payment options, session rules, and validity period.

Step 3: Evaluation#

The buyer verifies the seller’s identity and offer signature, then evaluates price, quality, operational need, and local policy.

Step 4: Session creation#

The buyer signs an acceptance. Both parties derive or agree on a session identifier that will link service events, payment authorizations, and proofs.

Step 5: Delivery and payment#

The seller delivers measurable service. The buyer signs value authorizations at agreed intervals. Either party may pause according to timeout, safety, delivery, or payment rules.

Step 6: Proof#

The application submits commitments for the offer, acceptance, delivery intervals, relevant machine state, and payment references. HashAnchor returns receipts after batching and anchoring.

Step 7: Settlement#

The seller or a settlement service submits the payment authorizations. Multiple small authorizations may be aggregated when the payment protocol permits it.

Step 8: Completion#

The final event links the delivered quantity, total authorized value, settlement result, and completion status. Both parties retain evidence suitable for reconciliation or dispute handling.
