The Internet of Things (IoT) has rapidly evolved over the past few years, providing a way to connect modern devices over a secure network to create smarter, automated environments. However, IoT networks face several challenges, including scalability and interoperability problems. As IoT networks grow in size due to increasing demand, they become more complex and difficult to manage and face security and efficiency challenges. In recent times, Blockchain, a decentralized and secure ledger technology, has been presented as a potential solution to these challenges, offering a way to build more efficient, scalable, secure, and interoperable IoT networks. There are projects like SHREE (https://shreetoken.com/) creating innovative blockchain solutions to help streamline IoT networks and boost efficiency.
Understanding Challenges of Current IoT Systems
Traditional IoT systems face various challenges such as:
1. Scalability Issues:
IoT networks normally rely on centralized systems to manage communication and data transfer between devices. These centralized models have limited capabilities and can reduce performance as the network size and demand increase. This can lead to communication gaps, high operational costs, and low efficiency.
2. Interoperability Restrictions:
IoT devices and networks often operate on restricted protocols, making cross-platform communication a major concern. For example, smart devices from different manufacturers may struggle to communicate or share data effectively, affecting the system's performance and scope.
3. Security & Transparency:
IoT networks may face security concerns due to their centralized control. They are prone to hacking and cyberattacks, compromising sensitive data stored and managed by these devices. Moreover, there is a lack of transparency in the origin and authenticity of data transmitted over centralized networks.
Blockchain as a Solution to the IoT Industry Problems
Blockchain technology can address the scalability and performance challenges of IoT systems by offering a decentralized way for IoT devices to communicate and transfer data. Decentralization means the network works autonomously without a central authority, ensuring complete transparency, high security, and seamless communication, even between devices from different manufacturers. Here's how it enhances the scalability and interoperability of IoT systems:
1. Decentralized Architecture
By eliminating the need for centralized control, blockchain streamlines data processing and storage across a network of thousands of distributed nodes, reducing the probability of human errors and increasing network security. Blockchain-based IoT networks can scale seamlessly and process vast amounts of data without compromising performance since there is no limit to the number of nodes that can be added to a blockchain network.
2. Smart Contracts for Automation
Blockchain utilizes smart contracts–self-executing agreements–enabling IoT devices to communicate autonomously, reducing the need for manual verification or approval. This reduces processing time and improves security. For instance, in a blockchain-based smart supply chain network, IoT devices can automatically process payments once goods are delivered, reducing costs and enhancing user experience.
3. Interoperability Through Standardization
Blockchain's global standardized protocols ensure seamless communication between different IoT devices and platforms, even across different blockchain networks. Blockchain-powered IoT networks operate on a common, globally accessible framework, enabling devices with different origins to exchange data seamlessly and securely.
4. Enhanced Security and Trust
Blockchain can help enhance security in IoT networks by reducing middleman interference and employing advanced cryptographic hashing. Blockchain’s immutable ledgers are practically impossible to penetrate. It ensures a tamper-proof and transparent recording of transactions and enables verification of data authenticity when needed.
Real-World Applications of Blockchain in IoT
Here are some examples of industries that can benefit from the collaboration of blockchain and IoT:
Smart Supply Chains
Blockchain-based supply chain networks benefit from improved traceability and transparency. IoT sensors can track the live status of goods in real-time, while blockchain ensures secure and immutable recording of this data in its ledger. Smart contracts can automate payments and logistic operations, increasing overall efficiency.
Healthcare IoT
In healthcare systems, IoT devices are used to monitor, record and share patient information with medical professionals. The integration of blockchain technology can help improve security in transactions, making it easier to transfer and authenticate data with access only to authorized personnel. It also ensures seamless interoperability between devices across different networks, hospitals and cities, improving treatment efficiency.
Smart Cities
Smart cities use IoT devices and networks to automate resource management like energy and water supply and transportation. By facilitating seamless and secure communication between these devices, blockchain can ensure efficient resource allocation and reduce delays and costs.
