Blockchain and IBM Watson IoT Platform can provide benefits for IoT applications by creating an immutable record of IoT data transactions. Blockchain allows devices to directly write data to a distributed ledger without centralized control, ensuring trust and transparency across business networks. The Watson IoT Platform can connect devices, integrate data sources, perform analytics, and manage risk. It also has capabilities to interface IoT data with a private blockchain via APIs. This allows shared access to IoT data among relevant parties in use cases like supply chain management, part lifecycle tracking, and smart buildings. Examples demonstrate how blockchain could record data for shipping, regulatory compliance, and carbon credit exchanges through the Watson IoT Platform.

Blockchain and Watson IoT
• Blockchain leverages distributed replication
• Eliminates the overhead of central control and
management
• Only business partners involved in the
transaction can access and supply IoT data
• Partnering with key clients in aerospace,
automotive, supply chain, and manufacturing
industries
The Watson IoT Platform has built-in capability that lets you add IoT data to a private
blockchain ledger via API. This provides for shared transactions with tamper-resistant
records, transparency and trust.

10. How it works
• IBM Blockchain provides the private blockchain infrastructure of distributed peers that
replicates the device data and validates the transaction through secure contracts.
• Watson IoT Platform translates existing device data, from one or more device types,
into the format needed by the blockchain contract APIs. The blockchain contract
doesn’t need to know the specifics of your device data.
• Watson IoT Platform filters device events and sends only the required data to the
contract.
• Storing IoT data as part of a indelible ledger on a private blockchain can help build
trust across business networks.
