12. Integration Paths
12.1 Device-First Integration#
Use this path when the machine hardware and firmware can be modified.
- Port or configure the BoAT MER platform abstraction layer.
- Provision a device identity and keys.
- Select buyer, seller, or full build profile.
- Add the required communication and payment adapter.
- Define local authorization rules.
- Sign operational events on the device.
- Submit event hashes to HashAnchor through a gateway or application.
This provides the strongest device-origin guarantee.
12.2 Gateway Integration#
Use this path for legacy machines that cannot run BoAT MER directly.
A trusted edge gateway can:
- communicate with the existing machine protocol;
- maintain a machine-scoped identity;
- translate machine state into signed events;
- enforce commercial policy;
- initiate payment or proof workflows.
The trust boundary moves from the device to the gateway, which should be clearly represented in receipts and identity metadata.
12.3 Cloud/Application Integration#
Use this path to test a business model before embedded deployment.
The application can integrate HashAnchor, payment APIs, and simulated machine identities. Once commercial logic is validated, signing and policy enforcement can move progressively closer to the physical machine.
This staged model reduces initial integration cost while preserving a route to stronger machine-native trust.
12.4 HashAnchor-Only Integration#
Existing platforms can adopt HashAnchor without adopting the full TLAY stack. Common use cases include:
- tamper-evident IoT logs;
- supply-chain milestones;
- AI-generated industrial decisions;
- maintenance and calibration records;
- energy and carbon data;
- payment and service reconciliation.
HashAnchor becomes an entry point into the broader TLAY network.
12.5 BoAT MER-Only Integration#
Developers can use BoAT MER for machine identity, signing, or payment authorization while using their own proof infrastructure. Open interfaces reduce lock-in and make the runtime useful before the full TLAY network is adopted.
