Why Web 3 Should Be Green And Sustainable?

This article was published as a part of the Data Science Blogathon.


The arrival of Web 3 is about unlocking unimaginable value. The next chapter of the internet heralds a new economic paradigm, and emerging technologies will enable new business models that will transform the world. Over the next few decades, harnessing these opportunities will be a defining challenge for all businesses. At the same time, climate change is one of humanity’s most pressing issues, and addressing it is everyone’s responsibility. The ability to provide high-performance computing and infrastructure to support Web 3 development while minimizing environmental impact is critical to its future success.

The High Energy Consumption of Web 3 Technologies

Even for experts in the field, assessing the environmental impact of such a vast ecosystem as a digital communication network is a guessing game. How many identifiable data centers are there? How many stealth centers exist (especially in the military and government sectors)? How many people are working above or below their capacity? How much power do they draw from the grid?

All transactions must be considered when calculating the internet’s power consumption and carbon footprint. Because Web3, like the traditional web, has layers, the only way to assess its long-term viability is by segment.

Web 3’s data traffic layer is already operational. The number of submarine cables, antennas, and data centers can be used to calculate the environmental impact. The impact of manufacturing these components, the impact of installation, and the impact of electricity use are all factors.

In terms of electricity consumption, the total data transmission consumption of the entire Internet amounts to somewhere between 260-340 TWh (roughly 1.4% of global electricity consumption).

The end-use layer, which corresponds to the devices (smartphone, notebook, etc.) that make transaction requests, is used for various purposes other than web3. It is even possible to argue that if web3 did not exist, it would have little impact on the production of these devices because devices geared solely or primarily for blockchain applications are still scarce on the market.

A similar conclusion can be drawn about the storage layer, which employs traditional computers and servers. There are few data centers dedicated to web3 data storage because the full node concept consists essentially of one computer per node, and it does not make much sense to build a large facility for this purpose, except in the case of renting virtual machines, where different users hire space in cloud services. However, these exist primarily to serve web2.

The Global Scenario:

Climate change is a worldwide coordination issue. The system has failed to coordinate effective policies and capital investments required to address humanity’s most pressing threat. Accelerated action and ambitious climate policies are required to adapt to climate change and rapidly reduce emissions to avoid greater loss of life, biodiversity, and infrastructure.

Global coordination technologies that can cut through the mass bureaucracy of climate action are desperately needed. This is where Web3 innovation could come in handy.

The Environmental Problem of Web 3

The consensus layer is the real source of web3 criticism. The Proof of Work protocol is responsible for the bitcoin network consuming more energy than some countries.

PoW mining involves computers performing numerous calculations. These calculations are lottery-style attempts to “guess” a correct number. The first person to get it right gets to mine a block. Every 10 minutes, a new block is mined in the network, and the process is restarted. The more computing power a miner has, the more likely he will mine a block.

This is why Bitcoin consumes so much energy today. As the network’s usage and popularity grow, so does the financial value of Bitcoin, which encourages more miners to participate.

Currently, the energy cost of Bitcoin’s PoW is around 200 TWh, which is comparable to Thailand’s total consumption. Bitcoin’s annual carbon footprint is approximately 114 Mt CO2. This energy consumption is expected to rise in the future. However, Bitcoin supporters argue that the use of clean energy is increasing. According to the Bitcoin mining council, sustainable energy accounts for nearly 60% of the energy cost of Bitcoin mining today.

Making Web 3.0 Green and Sustainable

There are many ways to work for a Green Web 3 future. They are:

Proof of Work consumes a lot of energy. The Proof of Stake protocol (Pos) operates differently than the Proof of Work (PoW) protocol. Instead of computers attempting to hit a number, PoS selects the miner based on the number of tokens he owns. The more tokens an agent possesses, the more likely he is to be selected. This explanation is quite simplistic and ignores several security and decentralization aspects of PoS protocols, but the basic concept is based on it.

There is no mining because there is no need to look for random numbers. Because of this, “miners” in a PoS protocol are referred to as “validators.” PoS protocols are thought to be long-lasting. The energy cost of a PoS machine is comparable to that of a laptop.

In the case of PoW, specific computers, known as ASICs, have been developed to do the job. A modern ASIC can consume up to 3000 W/h, and dozens of these machines can be found in a mining farm.

This is yet another critical aspect of the PoS protocol. There is no such thing as a “mining farm” because a pool only needs more delegated tokens, not more computers, to increase its chances of being chosen to validate a block. So, in addition to the energy operation benefit, there is an infrastructure benefit.

Crypto Coral Tribe is a community of 6565 NFTs that uses art and technology to drive marine and wildlife conservation. This includes using the funds raised from their first pledge to plant 3000 corals across three continents.

A community-driven approach is urgently required to design innovative climate solutions that leverage local and indigenous knowledge while iterating on alternative methods of driving impact. Web3 can accomplish this. Several Web3 projects are already in the works to redefine how humans interact with natural resources and the larger environment.


The proliferation of green Web3 initiatives eventually reflects a greater awareness of the critical need for sustainability and may allow us to envision a feasible reconciliation between technology and the environment.

To conclude:

Although web3 represents an evolution over web2 in many ways, it is unlikely that web3 will be more environmentally friendly than web2.

Decentralized networks necessitate a complex infrastructure and the implementation of consensus protocols, which can be energy intensive in some cases.

Now is the time for companies eager to stake their claim in the next frontier of computing, both in the metaverse and in driving the underlying software toward a more sustainable future.

Web 3.0 is here to stay and change the world. The responsibility of making it green and good for the environment falls on the people making the change.

3 Best Virtual Guitar Apps And Software

3 best virtual guitar apps and software




A guitar app for PC will help you exercise rhythm and create new songs.

Our selection of premium audio software includes a

virtual guitar PC emulator.

We’ve also included the

best virtual guitar app

for PC for acoustic lovers.

If you love electric guitars, know that there’s a

guitar app for PC suited for you.

If you are looking to transform your Windows 10 tablet, or desktop device into a guitar player, you should know that there are apps that you can use for that.

We have featured below three such apps that we consider to be the best for Windows 10 guitar aficionados.

The guitar is one of the greatest instruments you can play. It allows anyone to create great music and to play almost any possible song, but, like most musical instruments, it takes some time to master.

Adobe Audition is the best tool for designing sound effects, including a virtual guitar instrument effect.

After creating your own artwork of music sound using instruments and vocals, you will have to improve the sound of the audio for a more precise effect.

Adobe Audition can be the right choice to craft smooth and textured effects by modifying vocals and drums from the Guitar Suite panel.

As well, you have the possibility to improve the sound of the guitar that you already created by optimizing or altering it, in order to achieve high-quality audio.

Moreover, there are a lot of features for virtual instruments like guitars, so you are free to create a tighter sound effect or to reduce dynamic mixture in the Compressor tab.

As well, the guitar sound can be improved by applying filters, modelers, and by using Distortion features for the professional and expressive performance of the artist.

You will be able to filter frequency, set the resonance, to amplify, and to mix the audio. Adobe Audition will ease the overall process of mixing and editing audio.

The tool allows you to work on more layers and effects at the same time, especially if you use more instruments and want to improve aspects of the vocal in the audio file.

Besides editing sound effects, Adobe Audition gives you the option to record and mix podcasts, to remix the songs effortlessly and automatically, and to fix audio files with the help of frequency display and Diagnostics features.

Adobe Spark

Adobe Spark is the best tool for audio effect design, so feel free to try it out!

With the Play Guitar! app for Windows, you can practice playing in a virtual environment, when you can’t pick up the real thing.

The Play Guitar! app for Windows is an awesome way to learn a few chords also, so you can give it a try if you are only now starting to learn to play guitar.

The app is in a sense similar to Piano8, which we reviewed a while back, and if you liked that one, then you cannot like Play Guitar!

Expert tip:

The app is very similar to the Android guitar app that so many loved, and therefore, I think that those who have moved to Windows 10, Windows 8 will like just the same.

The user has two possibilities to use the app:

In Chord Play, you can also see where you have to press in order to create the specific sound of each chord. This can be a great way to memorize them before moving to a real guitar, or for practicing.

The guitar that is used in this app is an acoustic guitar, but if you want to learn how to play an electric guitar, there is a specialized app for that as well.

⇒ Download Play Guitar!

Rock Guitar! app  has the same interface as Play Guitar!, with the same buttons and features. This makes it very easy to use by anyone.

Also, the sensitivity of both apps is awesome, so you won’t ruin your song by pressing multiple cords at once. I salute the developer of these two apps for a fantastic job!

Rock Guitar!’s developer recently updated the app adding a series of interesting new features, such as virtual guitar support, a new chord viewer, and chord editor.

Both Play Guitar! and Rock Guitar! are awesome apps that should not miss from the device of anyone who likes music. The apps are both simple, the sound is great and the difference between the chords is audible.

The app received mostly positive reviews and many users confirmed that using it feels like using a real guitar:

3 Tips To Avoid Fake Apps In Windows App Store

Everybody has their own app store now! Apple has its App Store, Google has Play Store and now Microsoft has its own Windows Store, thanks to Windows 8. But to get some traction and to compete with other app stores, Microsoft focused too much on the quantity of the apps rather than the actual quality of all those apps.

This led to quite a stir when it was exposed that there are many fake apps designed to cheat users on their money and innocence. Of course, Microsoft took quick action and cleaned out some hundreds of fake apps and also enforced some tight rules to avoid future problems. Nevertheless, fake apps always exist. So here are the top 3 tips to avoid fake apps in Windows app store.

1. Don’t Always Trust User Reviews

Well, this looks counter productive but please don’t always trust the “user reviews” part of the apps in the app store. This is because some app developers are using unorthodox methods to acquire positive reviews, like forcing users to review the app even before they use it, buying fake reviews, etc. Because of these manipulations, we cannot take user reviews for granted. Microsoft also didn’t implement any strict policies when it comes to the app reviews. So whenever you are trying to buy an app from the Windows app store, try to get more details on that specific app or developer by searching on the Internet rather than relying on the user reviews.

2. See Who’s the Developer

3. Don’t Pay for What You Can Get for Free

There are plenty of misleading apps in Windows app store that make money off free services. Some examples are VLC guides, VLC keyboard shortcuts, YouTube tips, etc.., that come with a fee, with some even demanding ridiculous payments like $9.99 just to act like a rip off of the popular free services like YouTube, Twitter, Facebook. Always be skeptical about what you are buying and don’t ever pay for what you can get for free.


Whether Microsoft has done a good job or not to maintain the integrity of its Windows Store, we are not sure. We can only do our part and be more diligent in checking out the app before we make the purchases. This includes both Apple’s App Store and Google’s Play store as well.

Web Developer Vs Web Tester

Difference Between Web Developer vs Web Tester

Web development, programming languages, Software testing & others

What is Web Development?

Everything you see on the internet is put up on numerous websites. But how are these websites created? Who is responsible for all the content displayed on these websites? Who designs all those webpage layouts? Where do the features and designs on the websites come from? Who programs these websites to deliver the users the exact information they might be looking for?

Professional Web Developers and Web Designers do all the above-listed jobs. But before we go on to what web developers do, it is essential to know what web development is. Web development is a broad term that includes working out all the technical features of a website. It has everything from creating a website to maintaining it. Web development generates websites that are fully functional and user-friendly. Web development is not a one-time process. After creating a website, it becomes essential to keep it updated. Web development requires professional skills and abilities, technical skills, and appropriate degrees.

Head-to-Head Comparison Between Web Developer vs Web Tester (Infographics)

Following are the top differences between web developer vs web tester:

Web Developer

It is the job of a web developer to create a website, and creating a website means designing the website’s layout and putting up the content on the website as per the directions of the clients and as per the requirements of the users. Web developers don’t just build websites. There is a lot more than web developers do, and their job ranges from generating the layout and features of a website to understanding the graphic design and all the programming features of a website. They are also responsible for writing and editing the content of the websites and the complex process of building WordPress themes for websites.

To be a web developer, you also need to master specific professional skills, and also you need to know several programming languages. And then, there are the coding skills you need to remember to be a web developer. As a web developer, you meet the client, discuss their needs, and then accordingly, you build up the website which caters to the needs of the client and the needs of the users. A website must be user-friendly; that is what most helps generate website traffic. The web developers work out all the technical requirements for making a website and keeping it updated. It is like growing a flower. For a flower to blossom, you need to keep nurturing it by watering it and taking due care of it till it blossoms into a mature flower. Similarly, a web developer first creates a website and then takes care of it by occasionally prioritizing the tasks and updating the site.

Technical requirements for a web developer:

It might look like being a web developer is an easy job, but it takes many things together to be a perfect web designer. It would help to have at least a bachelor’s degree and the required technical skills and knowledge of computer programming. You can also take up some online courses to learn about web development. You must have basic web development skills. The fundamentals of design imaging, multimedia programming, animation skills, basic web designs, content writing and editing, knowledge of databases, etc., go into the making of professional web developers.

What Salary can you Expect as a Web Developer? How to be a Good Web Developer?

Doing a job and then doing it well always pays off. You don’t just want to enter a field of work; you want to excel in every possible manner. It would help to remember the following things to be a good web developer.

1. Good Communication Skills 2. Passion 3. Be the Perfectionist

People don’t want their work done by someone who can’t cross-check it. You should be a perfectionist if you want to be a web developer and a successful web developer, for that matter. After all, you don’t want to commit a mistake that might break the website you have worked so hard on.

Web Testing

When you are done building a website, you often go online. But before you go online and be available for the users, you must test the website to find any problems or issues. If you find any, you try to correct the issue before you go live and publicly reveal the website. Web testing is a kind of software testing that is conducted on the newly formed website to check for any issues and problems with their proper functioning, programming, security issues, the issues related to the availability of the website across users of various devices like mobile phones, laptops, etc. and also to see if your website is designed to play host to potential traffic which may be called as load testing. The web testers do all this testing.

Recommended Courses

What do Web Testers Do?

Testing a website for any potential errors or issues is very important. As a web tester, you must check the website for any possible functionality disorders and issues and then set them right. After a website is designed, the users expect fairly reliable and functional websites that work fairly well across all devices. As a web tester, you must perform important tests on the newly built websites before launching them.

Web Tester Tools and Techniques

Here we are going to understand how both the tools and techniques differ.

1. Functionality Testing: Your clients want their websites to function flawlessly and accurately. The functionality tests include checking all the links in the webpages, the database connections, the cookies and the forms, media components, search, libraries, and scripts and validating HTML and CSS.

3. Interface Testing: Two main interfaces are:

The web server and application server interface

Application server and database server interface

See if the interactions between these interfaces are functioning correctly. Also, you need to check for errors and connections.

4. Compatibility Testing: It includes Browser compatibility, Operating system compatibility, Mobile browsing, and Printing options. You have to check for all these compatibilities. You can try operating the website across browsers, operating systems, and mobiles to check for compatibility issues.

5. Performance Testing: This test is conducted precisely to test the web load. It includes web load testing and web stress testing. You need to see if the webpage is sustaining to heavy load. You can try testing the webpage across networks with varying speeds and connectivity.

6. Security Testing: Generally, web applications save information about the users, their files, details, billing, and payment information. It would be best if you made sure that the users can trust the website and put in proper security checks to maintain the users’ trust. It is essential to keep the data of the users safe and secure.

It would help if you ensured the data was kept secure and private. You should limit the access before granting access to sensitive data. You need to check for any possible security issues and correct them.

Web Developers and Web Testers

Now you must have gained a fair deal of information regarding what web developers do and what web testers do. The work of the two is correlated. While it is the web developer’s job to create and maintain the websites, the web testers check for and address various issues and problems that this website might have. The two fields are interrelated. Neither can work without the other. A web developer may develop a website but cannot launch it until a professional web tester has put it through various tests of varying levels. To create a well-designed, perfectly functional, and reliable website, it is essential to involve both the web developer and the web tester.
