Blockchain as the Foundation for the Internet of Things: Application Scenarios and Use Cases
The article argues that blockchain, rather than IoT, underpins the IoT era and explores application scenarios such as device address assignment, IBM's ADEPT system, supply‑chain cost reduction, QR‑code delivery verification, and a blockchain‑based DNS service for secure, low‑cost public networking.
Some once believed that the Internet of Things (IoT) was the foundation of the big‑data era; the author contends that blockchain technology is actually the foundation of the IoT era.
Application Scenario Analysis
One possible scenario uses a Transaction to trigger actions, assigning each device an Address with an injected fee, enabling operations such as PM2.5 monitoring data collection, server leasing, network‑camera data access, and DNS services.
IBM
IBM has invested decades in IoT research and is now exploring blockchain to reduce IoT application costs. In early 2015 IBM partnered with Samsung to develop the ADEPT system.
Logistics Supply Chain
Blockchain can lower logistics costs, trace the production and shipment processes, and improve supply‑chain management efficiency, making it a promising application area. For example, carriers can scan QR codes to confirm delivery and automatically collect pre‑agreed fees, as discussed in articles on how blockchain transforms supply‑chain finance and brings transparency.
Skuchain has created a blockchain‑based supply‑chain solution that synchronizes product and fund flows while mitigating counterfeit issues.
Public Network Services
Current Internet services such as DNS rely on near‑free access; without DNS, websites would be unreachable. Such foundational services must be secure, reliable, and low‑cost.
Blockchain possesses these qualities, and a blockchain‑based DNS system could eliminate erroneous queries while providing stable, trustworthy service.
