Review Questions

• How does blockchain technology enhance security and privacy in wearable devices?
  • Blockchain technology enhances security and privacy in wearable devices by providing a decentralized system for storing and transmitting data. This means that personal health information collected by wearables is not stored in a single location vulnerable to breaches; instead, it is distributed across multiple nodes. The use of cryptographic techniques ensures that only authorized parties can access the data, significantly reducing the risk of unauthorized access and enhancing user trust.
• Discuss the potential impact of smart contracts on the functionality of wearable electronics.
  • Smart contracts can revolutionize the functionality of wearable electronics by automating interactions based on predefined conditions. For example, a wearable device could automatically execute a contract for a fitness challenge by verifying the user's performance metrics stored on the blockchain. This could enable seamless transactions without intermediaries, promoting efficiency and reducing costs while enhancing user engagement through real-time rewards and incentives.
• Evaluate the challenges that may arise when integrating blockchain technology into wearable and flexible electronics.
  • Integrating blockchain technology into wearable electronics presents several challenges including scalability issues, as current blockchain networks may struggle to process the vast amounts of data generated by wearables in real-time. Additionally, there are concerns around energy consumption associated with maintaining blockchain networks. Ensuring user acceptance is another challenge, as individuals may be hesitant to trust new technologies. Finally, regulatory compliance related to data privacy laws must be navigated carefully to protect users' rights while leveraging the benefits of blockchain.
