How does IoT work with blockchain?

IoT enables devices across the Internet to send data to private blockchain networks to create tamper-resistant records of shared transactions. IBM Blockchain enables your business partners to share and access IoT data with you — but without the need for central control and management. Each transaction can be verified to prevent disputes and build trust among all permissioned network members.

How you benefit by combining IoT with the power of blockchain

Build trust in your IoT data

Each transaction is recorded, put into a data block, and added to a secure, immutable data chain that cannot be changed — only added to.

Rely on added security

With the Watson IoT® Platform you can select the data to be managed, analyzed, customized, and shared among permissioned clients and partners.

Gain greater flexibility

The IBM Blockchain Platform is open, interoperable and is built for your multicloud world, using the latest version of the leading Hyperledger Fabric platform, optimized for Red Hat® OpenShift®.

Generate new efficiencies

IBM Blockchain streamlines processes and creates new business value across your ecosystem by drawing on the data supplied by IoT devices and sensors.

Applications of IoT and blockchain

Freight transportation
Moving freight is a complex process involving different parties with different priorities. An IoT-enabled blockchain can store the temperatures, position, arrival times, and status of shipping containers as they move. Immutable blockchain transactions help ensure that all parties can trust the data and take action to move products quickly and efficiently.

Component tracking and compliance
The ability to track components that go into an aircraft, automobile, or other products is critical for both safety and regulatory compliance. IoT data stored in shared blockchain ledgers enables all parties to see component provenance throughout a product’s life. Sharing this information with regulatory agencies, shippers, and manufacturers is secure, easy, and cost-effective.

Log operational maintenance data
IoT devices track the state of safety for critical machines and their maintenance. From engines to elevators, blockchain provides for a tamper-free ledger of operational data and the resulting maintenance. Third-party repair partners can monitor the blockchain for preventive maintenance and record their work back on the blockchain. Operational records can also be shared with government entities to verify compliance.
