Blockchain can be used to track the sensor data measurements and prevent duplication with any another malicious data.
Deployments of IoT devices can be complex, and a distributed ledger is well suited to provide IoT device identification, authentication and seamless secure data transfer.
Instead of going through a third party for establishing trust, IoT sensors can exchange data though a blockchain.
A distributed ledger eliminates a single source of failure within the ecosystem, protecting a IOT device’s data from tampering.
Blockchain enables device autonomy (smart contract), individual identity, integrity of data and supports peer to peer communication by removing technical bottlenecks and inefficiencies.
The deployment and operation costs of IoT can be reduced through blockchain since there is no intermediary.
IoT devices are directly addressable with blockchain, providing a history of connected devices for troubleshooting purposes.
