You Are Here:Decentralised IoT and Block Chain

IoT is no more a new term in today’s technological era. It has indeed revolutionized thousands of personal and professional ecosystems.
However, under the fascinating name of Internet of Things (IoT), we often overlook some of the key issues that already had or may arise with the growing needs and demands. The current IOT system relies on a centralized clinch of communication models involving centralized cloud databases/servers to identify & authenticate different devices attached to it, which seems to throw a great deal to us. But, will it be able to respond effectively to the growing need of the gigantic IOT world of tomorrow? And what about the expenses to install such large IOT system involving a huge number of devices in it. Ever thought what would happen if someday, the whole cloud server collapses or the centralized database encounters a failure? Won’t it be better if instead of two adjacent devices communicating via internet gets to communicate directly with each other?

Who’s the saviour here?
The answer to all such issues is the Decentralised IOT.

The Decentralized IoT is a heterodox method for holding up a communication. Moreover, unlike communications methods with centralized servers, it works on an entire network of computers such that there is no single point of vulnerability and won’t allow any single entity to control the network. Bitcoin was the first to bring this technology into the limelight as it was the first successful cryptocurrency that works on the brilliant decentralized network of computer systems. Bitcoin runs on BlockChain.

What is a BlockChain?

The blockchain is actually a digital ledger which records the data or the transaction made in bitcoin or cryptocurrency in a chronological manner. Originally, Block Chain was meant to power the Bitcoin, however, it is capable of doing much more than that.
The blockchain is minuscule of whole distributed ledger technologies that can be programmed to record and track anything of value, may it be financial data or medical health reports or any regular stats. Blockchains have indeed transformed the way of our communications.

Why Blockchains?
Here are few simplified reasons for which Blockchains proves to have a number of advantages over other technologies:-

1) The Way It Stores and Tracks Data:-
Blockchains stores information in batches called Blocks. These blocks are linked together in a chronological manner to form a continuous line, or better say, in a chain of data blocks.
If any change is intended in any particular record in a block then we don’t need to rewrite it, instead a new block is created which stores the information about the change in the respective block. Every change is recorded as with a creation of a new block in the ledger and thus it can easily be checked whenever required.

2) It Created Trust In The Data:-
Blockchain was designed to be decentralized and distributed across a large set of computers over the network. This decentralizing of the data and information reduces the ability for data tampering. How does it happen? Here are the few steps that are being followed:-
Firstly, a cryptographic puzzle must be solved to create a block.
The node which solves the puzzle shares the solution to all the nodes/computers on the network, as the proof-of-work.
The network verifies the puzzle solution for the block and if satisfied the block is added to the ledger.
The combination of all these enables verification of the block from each computer thus implying trust on each block of the chain.

3) No More Intermediaries:-
As the network builds trust for us, we can now directly rely on our data in real-time thus cutting down the intermediaries. As already discussed the current IoT technology relies on a single centralised server to authenticate and store data for and from different devices connected. However, with the use of Blockchain, the blocks of data has already been verified and so, it doesn’t need to be authenticated from any of the intermediate stations. The devices can directly communicate to each other knowing that the nodes are already authenticated and are truthful as they form a part of chain providing the restriction on any possibility for the data to get tempered. This will not only reduce time but also saves a lot amount of capital for us.

Blockchain & IoT
Blockchains, when coupled with IoT, brings a better way of its implementation. The devices enrolled under IoT will no longer have to communicate through the internet. They can directly communicate and access data over devices. Gone are the days, when IoT had huge installation and maintenance costs, now decentralized IoT along with Blockchains is the new solution. It has created a more and broader and clear picture of the progress in this field. This type of technology will no doubt, revolutionize the way we access, verify and transact our data and communicate with each other thus creating an unbelievable technological ecosystem for a bright future.
