The Blockchain and IOT Convergence

Internet of Things (IoT) has been making waves and fascinating the technology circles for some time. Creating a secure ecosystem of the IoT architecture has been an issue of the technology architects. Converging the blockchain technology with IoT can solve these issues is another which is being brainstormed.

We shall start our discussion by first understanding the basic building blocks of IoT infrastructure and its limitations. Then we shall discuss the blockchain technology in brief. We shall then study the feasibility of convergence of IoT and the blockchain technology.

IoT Basics:

Any IoT architecture can be represented by four basic building blocks:
1.     Things: These are the uniquely defined nodes or primary sensors to communicate without human interaction using various connectivity methods.

2.     Gateways: These are the intermediary channels between “Things” and the cloud to provide connectivity, security and manageability.

3.     Network Infrastructure: This comprises of the routers, aggregators, gateways, repeaters and other devices that control and secure the data flow.

4.     Cloud Infrastructure: The cloud infrastructure is the pool of virtualized servers and storage devices, networked together with computing and analytical capabilities.

Like any new deployment, there are certain challenges in IoT deployments as well. One of the major issues has been to channelize the data securely to the right place, at the right time in the requisite format. These may be aggravated by the design and implementation.

One of the biggest issues has been in the security and platform configurations of the virtualized IoT platforms supporting multi-tenancy. Other, related to this is privacy concerns.

Another issue of the IoT ecosystem is its centralized brokered communication model based on the client-server paradigm. IoT devices are identified, authenticated and connected through cloud servers. Connections between devices have to go through the internet, even if they are a few feet apart.
Existing IoT infrastructure solutions and their associated maintenance cost with centralized clouds are quite expensive. These costs will increase drastically with the increasing number of IoT nodes.

 Lately, the industry has visualized for decentralizing the IoT networks to solve the above issues.

This is by adopting a standardized peer-to-peer communication model to process the billions of transactions between devices. This should reduce the associated costs of installation and maintenance. Also, the cost associated with maintaining large data centres will reduce. With peer to peer networking, chances of collapse due to the failure of a single node will also be diminished.

The peer to peer networking also has its issues but the blockchain technology already has a well-matured ecosystem on peer to peer networking system. The pre-requisite for adopting peer-to-peer in IoT are: peer-to-peer messaging distributed file sharing and autonomous device coordination. All these pre-requisite aspects are matured features of the blockchain technology.

The Blockchain Technology

Blockchain has lots of features and applications which can be brought in use directly when using it for IoT applications.

The blockchain technology offers a system to record transactions in digital form in a secure and transparent, immutable and open way. So, in simple words, blockchain is a chain of blocks where each block contains some information. The information is a timestamped digital document which is not possible to backdate or temper. However, blockchain cannot work without the internet.

The blockchain is referred to as meta-technology. It can affect other technologies. Any blockchain application consists of a database, software application and connected computers called nodes, to name a few.

There are three types of blockchain: 1. Public Blockchain, 2. Private Blockchain and 3. Federated Blockchain.

In the context of the IoT, depending on the applications, any one of the blockchains can be used. Generally, public blockchain is recommended for IoT applications. The public blockchain is also protected using the method of public and private keys, and digital signatures.

The blockchain is a decentralized solution. No single authority can approve the transaction. Specific rules are pre-decided, it works on the basis of consensus to accept any transaction.

The blockchain is a secure technology. It is also called an immutable technology. If any of the records in a block of data is tampered or changed, the whole block is changed.

 The Convergence of Blockchain and IoT

The blockchain technology can be used to address the privacy and reliability concerns of the Internet of Things. It can also be used to track the billions of connected devices, enabling the processing of transactions and coordination between the devices. Ultimately, this will interpret into exhaustive savings for the IoT industry.

The decentralized approach of the blockchain can be applied to eliminate any single point of failure, thus creating a resilient ecosystem for the IoT nodes.

The blockchain ledger is tamper-proof as it is located on multiple blockchain nodes. The decentralized, autonomous, and trustless capabilities of the blockchain make it an ideal component to be an element of IoT solutions.

The blockchain can keep an immutable record of the history of smart devices in the IoT network. This enables the autonomous functioning of smart devices without the need for centralized authority.

The blockchain opens the door to a series of IoT scenarios that were remarkably difficult, or even impossible to implement without it.

By leveraging the blockchain, IoT solutions can enable secure, trustless messaging between devices in an IoT network. The blockchain will treat message exchanges between devices similar to financial transactions in a bitcoin network. Message exchanges can be enabled using the smart contracts function of the blockchain applications.

There are lots of exciting capabilities of the blockchain which can be integrated with the IoT to make it more feasible and cost-effective.

Smart City - A Red Alert to Humanity - A Right to Freedom

Out of 959,000 applications broke down from the Google Play store, 88 percent sent information to Google, as per Business Insider.

A little more than 42 percent of applications additionally sent information to Facebook, while a little more than 33 percent sent information to Twitter.

"Data that could be shared by means of 3rd party applications could incorporate things like age, sexual orientation, and area," detailed Business Insider. "The investigation said the middle application could exchange information to five tracker organizations, which could send the information along to firms like Google."

Google, be that as it may, questioned the aftereffects of the investigation.

"We can't help contradicting the technique and the discoveries of this investigation. It misrepresents common practical administrations like accident detailing an investigation, and how applications share information to convey those administrations," proclaimed a Google represent…

Hybrid photoelectrochemical and photovoltaic cells on the way to produce sustainable solar energy

In the mission for abundant, inexhaustible options in contrast to non-renewable energy sources, researchers have tried to harvest the sun's quality through "Oxygen-hydrogen split out," a new photosynthesis strategy that utilizes daylight to produce hydrogen gas from water.

But water-splitting devices have not yet proven to their potential because there still isn’t a design for making a system with the right mix of optical, electronic, and chemical properties needed for them to work.




Scientists in the U.S. Bureau of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Joint Center for Artificial Photosynthesis (JCAP), a DOE Energy Innovation Hub, have furnished you with a fresh, out of the box new formula for inexhaustible powers that may sidestep the confinements in the prevailing system.



A manufactured photosynthesis gadget is known as a "hybrid photoelectrochemical and voltaic (HPEV) cell" that transforms sunlight and water into now not …

Yet Another Facebook ploy of Marketing - Dont use Multi-Factor Authentication

Marketing is a huge game played everywhere with or without Intelligence at times. People are made out sarcastic in possible ways.

Why ?

Collection of data - Just for controlling a problem or cause you need data in general science but these top companies are applying it to human.

Finding who you are is their job to sell a product which you need is something curious.But they even make you feel about a product and  pop up your inside brain.



People talking about hackers of computer...

To be straight forward...This is ETHICAL HUMAN HACKING

Previously in regard to elections of US - Trump strategy of targeting social media as vote banks have been proved out to be successful.

Here comes another big one....

A Simple E-bike from General Motors

General Motors is as of now turning out to be second just to Tesla in impacting past the 200,000-vehicle roof for the government EV assess credit, and it has plans to create 20 new completely electric vehicles by 2023.





Some portion of that EV-wise technique, clearly—or a parallel one, maybe—includes e-bicycles proposed for "buyers around the world." Friday, the organization indicated first pictures of two e-bicycles it's created—one collapsing and one smaller—and that they'll be accessible available to be purchased in 2019.

"We mixed charge building know-how, structure gifts and car review testing with incredible personalities from the bicycle business to make our eBikes," said Hannah Parish, GM's chief of Urban Mobility Solutions.



So far GM has next to no data about the bicycle, and nothing on the specs, what number of it may fabricate, or who those bicycle industry accomplices are. Be that as it may, it guarantees "an exclusive drive framework t…

First Hydrogen Fuel Train

Hydrogen energy components are a greener method to control vehicles. Be that as it may, they have additionally been cost-restrictive.

Today, however, that is beginning to change — on Monday, German travelers boarded the world's first hydrogen-controlled trains.




The new trains transport passengers along 100 kilometers (62 miles) of track and can travel up to 1,000 kilometers (621 miles) on a single tank of hydrogen, reaching top speeds of 140 km (87 mph).

Hydrogen fuel cells generate electricity by combining hydrogen with oxygen, and their only byproduct is water. That makes the cells a promising energy source that produces zero emissions and very little noise.

Though they remain pricey, hydrogen fuel cells have advantages over batteries. Instead of recharging, for instance, you can just refuel them like you would a gas or diesel engine. And because train schedules are highly predictable, it’s easier to build refueling infrastructure.

New research is helping cut the cost of hydrog…
