A Brief Introduction to What is IoT and Blockchain
When talking about the Internet of things (IoT), it is basically an ecosystem that connects digital devices and objects to each other for interacting and transferring information in real-time, and that too without any human intervention. The technology is gaining a huge momentum in the market, a result of which is that it has been predicted that there will be around 75.44 Bn IoT connected devices worldwide by 2025.
Likewise, Blockchain is termed as a shared digital ledger that records all transactions in public/private peer-to-peer networks, such that every member of the network can access the records but can’t change them anonymously.
Now as the definition of the two trending technologies is cleared to you, let’s look at what challenges the IoT ecosystem is facing and what are the benefits of merging Blockchain with IoT.
IoT Challenges that Blockchain Resolves
Despite the growing advancements in this ecosystem and businesses & investors showing an interest in learning about IoT trends, the market is still suffering from various issues. A few of which are as follows –
1. Poor security
IoT enables multiple devices to access, exchange, and share data within the ecosystem. However, in the absence of human supervision and any authentication standards, it becomes much easier for hackers to hack any of the devices and use it as an entry point in the network and steal private and confidential information. In other words, the following types of security concerns are possible to exist-
- Software attacks – The connected device is infected via some kind of malware such as viruses.
- Physical devices attack – This involves unauthorized device control.
- Network attacks – Here, wireless vulnerability and denial of service attacks are considered for ruining the IoT ecosystem.
- Encryption attacks – Activities related to password cracking are brought into practice in this scenario.
Blockchain, in this scenario, helps with keeping a real-time track of history of all the connected devices and sensor data, checking for content duplicacy from harmful data sources, and providing consensus algorithms into the process to ensure identity verification and security advantages.
What’s more, blockchain acts as a decentralized database, making it difficult for anyone to gain access to sensitive information by hacking a particular centrally controlled system.
2. No liquidity
Though IoT has come up with innovative ways to make communication possible between industrial and domestic appliances, devices, and machines, the technology is still naive in terms of empowering machines to order their own replacement supplies and parts. This is yet another area where the potential of cryptographic blockchain for IoT can be applied.
3. Lack of trust
Another challenge prevailing in the IoT marketplace is lack of trustability.
Since every digital device can connect in the IoT network and gain access to information independently, there is a higher risk of collusion and distrust. The top IoT development companies fill this gap and add trust to the ecosystem with the involvement of blockchain in the IoT ecosystem. Aka, the technology having the characteristics of transparency, immutability, and decentralization.
4. Lower scalability
Since IoT systems operate via centralized architecture, it is becoming increasingly tougher for one to connect billions of devices into the same network. An impact of which is rise in network issues and hacker attacks.
Blockchain technology, here, introduces smart contracts in the networks that enable devices to function anonymously and securely by creating agreements that executes only when a specific task is completed.
5. Higher processing overhead cost
Currently, various third-parties are being asked to check and authenticate each micro-transaction to ensure security in the IoT network. This is not solely a time consuming process, but also an expensive affair.
Blockchain-based smart contracts mitigates these challenges by introducing the power of automation and eradicating the third-parties dependency.
Now while we have studied what Blockchain means to IoT, let’s take a look at some of the Blockchain of Things applications across industries.
Use Cases of Blockchain in IoT
1. Supply chain and logistics
As you might have been already aware of, a global supply chain entails many stakeholders like brokers and raw material providers, and multitude of payments and invoices. This makes the process complicated, time consuming, and with less-to-no transparency. Besides, the risk of delivery delays is also common.
Here, the adoption of blockchain in the supply chain management process introduces transparency, ease of payments, and saves time & cost by removing intermediaries and decentralizing the ecosystem. The technology empowers the businesses to enjoy a secure data exchange and a tamper-proof repository for cargo documents and shipping events, eventually resulting in less delays and frauds.
Whereas, IoT enhances traceability throughout the shipment process by empowering machines to share details in real-time across the network.
This way, the combination of Blockchain and IoT (aka Blockchain of Things) helps companies cope up with the challenges related to supply chain and logistics.
2. Smart Homes
Various smart home organizations are embracing Blockchain technology to make the data gathered and shared by smart devices immutable and prevent the risk of hacking.
They are also turning towards the idea of collaborating blockchain and IoT technology to provide users with an opportunity to share specific areas and devices with others safely and securely with giving them access to everything. For example, Comcast employs a permission-based ledger that enables smart home product users to grant access permissions remotely to others from their devices, such that these permissions can be revoked at any point of time. This could be particularly useful in situations like giving a virtual key of your house to a friend.
3. Healthcare and Pharmacy
Another industry that is revolutionizing with the adoption of Blockchain and IoT is Healthcare and pharmacy. The two technologies are helping the industry mitigate their traditional challenges like lack of data security, longer waited time, data inconsistency, and higher attached cost.
While the former technology eases the clinical research and drug development, supply chain management, and patient medical verification impact by introducing the power of decentralized distributed ledger and immutability of data, the latter ensures end-to-end connectivity and data sharing in real-time.
Likewise, Blockchain speeds up the processes by replacing third-party intermediaries with smart contracts. Whereas, IoT makes it possible for healthcare practitioners and pharmacists to get familiar with any uncertain medical signs and prepare for new chronic diseases quickly and efficiently.
Automotive is also one of the business verticals experiencing the impact of blockchain on IoT. The industry depends on the two disrupting technologies to leverage a wide range of benefits such as –
- The two technologies are easing the process of finding a vacant space for parking and is automating the payments via crypto wallet; making it termed as smart parking.
- Using RFID tags, car manufacturers are finding it easier to ensure proof of provenance for the spare auto parts and track the exact location of any particular car in the IoT-connected world. Whilst, blockchain is helping with storing and sharing this information globally in the form of a public distributed ledger.
- Blockchain of Things (BIoT) is also making it possible for customers to claim for insurance immediately and effortlessly using the power of smart contracts.
