Storage - peaq

Write and read compact JSON data (or file references) via lifecycle ROS 2 services. For high-throughput telemetry with IPFS, see Verifiable Storage.

Write data (`/storage/add`)

ros2 service call /peaq_core_node/storage/add \
  peaq_ros2_interfaces/srv/StoreAddData \
  '{key: "DEMO", value_json: "{\"ok\": true}", mode: "FAST"}'

Expected output:

response:
peaq_ros2_interfaces.srv.StoreAddData_Response(result='Success: 0xabc123...')

Each key can be written once per wallet; a second storage/add with the same key returns Error: ... (ItemTypeAlreadyExists). The same applies to key on peaq/storage/ingest, so give every ingest a unique key.

Read data (`/storage/read`)

ros2 service call /peaq_core_node/storage/read \
  peaq_ros2_interfaces/srv/StoreReadData \
  '{key: "DEMO"}'

Example response:

response:
peaq_ros2_interfaces.srv.StoreReadData_Response(value_json='{"account": "5F...abc", "data_type": "DEMO", "data": {"ok": true}, "exists": true, "read_status": "success"}')

Tips

Pair service calls with ros2 topic echo /peaq/tx_status to watch submitted transactions.
For files, publish via the peaq/storage/ingest topic handled by the storage bridge.
