Blockchain and IoT | Benefits, and Challenges


What is IOT?

    The Internet of Things (IoT) is an arrangement of physical things installed with sensors, programming, gadgets, and availability to enable it to perform better by exchanging data with other connected gadgets.  IOT uses RFID along with various detector technologies, wireless technologies and QR codes as a medium of communication.

    In straightforward terms, it is a system in which physical articles can exchange information inside or with other associated machines. IoT is a dream that is being constructed today with a desire for gigantic development in near future. IoT is a high tech innovation that reflects the future of exchanging information as well as computing, and its growth is based on the technical modification in various fields, such as wireless connectivity, increased data storage capacity.

Connecting numerous devices are made easier with IoT 

    IoT is important because it helps an object to represent itself in the digital format making it more superior than its mere form. Never again does the question relate just to its client, yet it is presently associated with encompassing items and database information.
    Most individuals expect about being connected as far as PCs and cell phones. IoT depicts a reality where something can be associated and conveyed in a sensible way. At the end of the day, with the internet of things, the physical world is getting to be one major data framework.
    In typical, IoT security flaws revolves around three parameters i.e. authentication, connection, and transaction. The major security concerns pop out when devices improperly verify, improperly connects, or improperly spends across any information to peripheral devices. With the introduction of Blockchain Technology, one can seamlessly alleviate the above concerns. The Distributed ledgers within blockchain act as a minor change to IoT networks bringing several killer apps within, no matter how physically the distributed systems are.

> Consensus protocol of Blockchain protects the IOT network from major malicious attacks.

> One of the most important goal of IoT is to track and verify the IoT network components. The immutable property of Blockchain makes these records extremely reliable.

> Smart contracts are a stunning asset in IoT systems taking into account a high level of coordination and authority. Especially with regards to overseeing transactions and interactions,  smart contracts guarantee appropriate union. IoT is constantly based on having the capacity to take the right action at the right time.

> Transactions are additionally helpful for IoT. Particularly, micro-transactions are a key part of guaranteeing financial feasibility and optimality in a machine-to-machine connection.

> A great deal of proposed IoT security spins around compelling encryption conventions. An initial correspondence check is initiated against the known device registrations for devices to confide with each other and propagate the communication between. 

> These registries act as the perfect focus for hacks and Blockchain technology depicts to be an extraordinary option for following these registrations and updating their framework.

By upholding a trustless and unalterable record of access and reconciliation, an IoT system builds a robust security to the network.


    IoT or Internet of Things is a system made by interfacing various devices to each other. For instance, it would be a system at home connected to a mobile through the internet. So also, in a work environment, it associates devices utilized for the business. Managers can control them with the goal that a consistent system is made between different gadgets in various areas. This could improve the proficiency and profitability of the gadgets and individuals utilizing them.


1. Scalability issue - The future of blockchain technology completely revolves around its scalability issues. As the size of blockchain grows the authority gets confined with minimal hands with no proper management of records. This often results in loss of data reliability and authenticity.

2. Handle power and time - As it demands the performance of  encryption calculations for every one of the items involved in Blockchain -based IoT network, the  IoT network is extremely distinct and contain devices that have very different computing capacities, and not every one of them will be equipped for running a similar encryption calculations at the desired speed.

3. Storage will be a hurdle - Blockchain removes the need for a central server to store transactions and device IDs, however, the ledger has to be stored on the computers themselves, and as time pass, the size of the ledger will increase. That is past the abilities of a wide variety of devices for example sensors, which have a very low storage limit.

Both IoT and blockchain are in their budding stages, with the guarantee of a future where machine-to-machine correspondence will be easy. As of now, organizations are putting efforts into blending the two innovations together. When consolidated, IoT and blockchain technology will give ventures a chance to flourish by effortlessly checking, following and securing information. At that point, the possibilities are never-ending, and you never recognize what's straight away!
