Q1- Explain why the future Internet of Things depends on Blockchain.

---

Internet of Think (IoT) is the system of interconnection with the devices in our lives. These days we are mostly using and promoting new technology which simplifies things in our life and helps in enhancing the experience.

If we understand it in simple language, (IoT) is a device technically connected by a network that exchanges data with other devices through the Internet. For this, sensors are used which are connected to the hardware of the device.

Example on IOT

---

let me give you the example on IoT, For example there is a car and that car has a GPRS unit, it is connected to the internet, now the car is moving fast and that car has an accident. And as soon as an accident occurs, an automatic call is sent from the side of the car to a police station that there has been a car accident at this location.

You send an ambulance here. In such a situation, you did not need to do anything because due to IoT, an SMS or call came directly from your vehicle, and help was provided to you. The police station also has a receiver device which is automatically receiving your SMS or calls.

I'll give you another example, Suppose I have to go out of the house urgently and there is no one in the house. I was in a hurry so forgot to switch off the house lights and fans. I am about 100 km away from my home. If there is a short circuit in the electrical power of the house, then a fire can also occur in the house.

So I have a device in my house and it is connected through sensors to all the lights, fans, air-conditioning. I have an application software attached to that divide in my phone, which runs through the internet, with the help of which I can turn off all the lights in the house. With the help of IoT, I did not even have to come back 100 km and my work was done from there in less time.

There are many examples such as smartwatches, Google Assistant, Alexa, GPRS, with the help of which we can make our life easier.

Blockchain and IOT

Previously there was little internet access, costly segmentation, and heavy chips and lack of technology hindered IoT. But in today's time, with the development of the Internet in the world, with the help of the Internet's best network and cheap chips, the problems that were there earlier were solved.

But today many problems will increase with the spread of IoT, some of them can be solved by using blockchain technology.

Privacy threats- There is also the fear of data theft, we know that in IoT the data is dumped in a centralized data server, from there any person can steal your data.

In today's time every person has a smartphone, a smartwatch in which live location is on, a smartwatch monitors our body activity, data of these devices centralized server is hacked then that person can access your location and Can monitor your activity.

This problem can be solved through Blockchain- I studied about cryptography where we learned that data can also be encrypted and decrypted, this we can do by using keys. That data can only be decrypted using the key that the authorized person would have. If still, someone gets access to the data unauthorizedly, then that person will not be able to decrypt the data without the decryption key.

We know that the data of IoT is stored in a centralized server, there is a high probability of hacking, hackers use many different types of attack (DDOS) distributed denial of service, (DOS) denial of service. These types of attacks affect the efficiency of the system and tamper, in most of cases, it is seen that the data is tampered with and altered.

Filament

The filament is a blockchain-based hardware and software developer company. Based in Reno, USA. The main objective of this company is to implement Blockchain technology in IoT. It solves the major problem of delayed transactions.

Basically, it acts as an intermediary to support IoT with Blockchain technology. This company was started by Allison Clift-Jennings in the year 2012.

IoT BLOCKCHAIN USE CASE

---

with the integration of blockchain technology, the filament has come up with many projects that are very relevant in the modern age.

1. With this integration, the filament has set a compatible standard to tackle the compatibility issues. With this, now all IoT that are to be built on ethereum blockchain will have some standards and this will give rise to compatibility among IoT devices.

2. With this, the filament has built a driver-less car. There are many cars out there but the problem with this is that one user's device can hack into the system and can change the codes to misuse it.
   But when these codes will be written on blockchain and no one can alter those.

3. Now not every device was made such that those would be integrated with blockchain technology. So to include that industrial device that is not compatible with this, a blocklet chip was introduced which will make those devices compatible with this.

Along with this, there are many such projects of filament but unfortunately not sufficient information is available on Google regarding this.

Conclusion:-

Now we are witnessing that every day a new IoT device to make us comfortable is introduced into the market. And these devices take our personal data. So the privacy has become more important and along with this security of data is also crucial.

To tackle of all these problems, the integration of blockchain technology with IoTs is essential so that the data of every user is kept safe and also no one can misuse anything by just altering some codes of any device.
