How does blockchain give patients control over their health information?

Through self-sovereign identity and consent management

By giving all healthcare providers unrestricted access

By making all health records public

By storing all data on a central server

How does blockchain provide a trusted record for digital twins?

By deleting old versions of the digital twin

By storing the entire digital twin on-chain

By creating an immutable history of changes to the digital twin

By using a central server to manage the digital twin

How does blockchain improve supply chain transparency?

By providing an immutable record of every transaction and movement

By hiding all transaction details from stakeholders

By using a centralized database controlled by one party

By allowing any party to modify records

A smart factory uses edge devices to process sensor data locally and needs to coordinate actions among machines without relying on a central cloud. The factory also needs to ensure that any firmware update to the edge devices is authentic and untampered. Which blockchain integration approach best supports these edge computing requirements?

Run a lightweight blockchain node on each edge device to maintain a shared ledger of device states and firmware hashes

Send all sensor data to a central blockchain in the cloud for processing

Use a private blockchain only for firmware updates, not for device coordination

Use a public blockchain for all edge device communication

What is a key benefit of using blockchain for government identity management?

Automatic deletion of identity records

Reduced identity fraud through decentralized, verifiable credentials

Centralized control of all citizen data

Publicly accessible personal information
