What is a way that blockchain can help in the field of IoT?
- It can protect the operating system of the IoT device.
- It can provide a secure transaction without cryptography.
- It can prevent device tampering.
- It can track sensor data measurements and prevent malicious data.
Explanation: Blockchain can be useful in several ways for the IoT:
Blockchain can track sensor data measurements and prevent malicious data.
It can provide IoT device identification, authentication, and secure data transfer.
IoT sensors can exchange data directly with each other securely and without the need for an intermediary.
A distributed ledger eliminates a single source of failure within the IoT ecosystem.
IoT deployment is simplified and operation costs of IoT are reduced because there is no intermediary.
IoT devices are directly addressable with blockchain, providing an immutable history of connected devices for trust and transparency.
