How Does Blockchain Secure IoT: A Comprehensive Review

In this review, we will explore the benefits and positive aspects of using blockchain technology to secure the Internet of Things (IoT). We will discuss the advantages of incorporating blockchain in IoT systems and identify the conditions where this approach can be implemented effectively.

  1. Enhanced Security:
  • Blockchain provides a decentralized and tamper-resistant architecture, making it highly secure for IoT devices.
  • The distributed ledger system ensures that data cannot be altered or tampered with without consensus from multiple participants, reducing the risk of unauthorized access or manipulation.
  • The use of cryptographic algorithms adds an extra layer of security, protecting sensitive information from potential hackers.
  1. Improved Data Integrity:
  • Blockchain technology ensures the integrity of IoT data by creating an immutable record of all transactions and interactions.
  • Each transaction is time-stamped and linked to previous transactions, creating a transparent and auditable trail of events.
  • This feature is particularly beneficial for sectors like healthcare, supply chain management, and financial services, where data accuracy and trustworthiness are crucial.
  1. Increased Transparency and Accountability:
  • Blockchain's transparent nature allows all participants in an IoT network to view and verify data, ensuring transparency and establishing trust among parties.
  • Smart contracts, which are self-exec
A blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.

What is the meaning of IoT in Crypto?

Key Takeaways: The Internet of Things (IoT) and crypto are converging technologies that can enhance security, trust, and efficiency in various sectors. Blockchain technology, the foundation of cryptocurrencies, has the potential to address security vulnerabilities and traceability concerns in IoT networks.
