Explain Web 3.0 and Blockchain Developer in 2022

 

Explain web3.0

Web 3.0 can change the web world as far as we might be concerned everlastingly; you're still right off the bat in getting the pattern and building your first blockchain application gaining the abilities to find a lucrative line of work or doing the web3.0 projects that can make you cash the eventual fate of the web isn't simply it's here to come. It's developing quickly, so hello, and welcome to my article since. The universe of web3.0 is new. I've chosen to give you the complete guide on how we can learn it bit by bit, beginning with any new advances. It tends to be overpowering. I know this web3.0 guide will direct you from uncovered beginnings to finish dominance we will cover everything from the fundamental structure squares of blockchain the entire way to the most current web3.0 advancements toward the finish of this article, you'll know definitively how you want to turn into a remarkable blockchain designer close by this video, I've likewise arranged a total web3.0 guide and a robustness a cheat sheet that covers all that you really want to turn into an incredible web3.0 engineer, the aides cover everything in bit by bit guidelines and even incorporate blockchain project thoughts that you can construct, send and place in your portfolio to track down another profession you can painstakingly peruse these extreme aides article and use them as a source of perspective on your web3.0 improvement venture at whatever point you're uncertain what to realize straightaway, and best of all it so ensure you read this article right presently look down, the aide actually, I'd strongly recommend you until the end of this article although the guides are excellent as quick reference points this article will provide you everything you need to become a professional web3.0 developer an online learning community with thousands of inspiring classes for anyone who wants to learn new skills as I was in the process of creating the ultimate web3.0 developer roadmap as you. Read in the intro. I needed to revisit web3.0 from beer beginnings; that's why I browsed the courses.

 

     If you're a more experienced developer, you'll love their more advanced courses; if you want to start learning for free, 1000 people searching about the web3.0 roadmap that will lead you to become a Web 3.0 developer before we dive into the roadmap first we need to understand what exactly web3.0 is and for that, we need to understand the differences between web 1, web 2 and Finally, Web 3.0 web 1.0 refers to the first stage of the worldwide web between 1991 and 2004 we saw the first generation of the internet, which was mostly a bunch of static sites on the web It looked something like this. It was mostly just one big website, including hyperlinks to different sites whenever you loaded up a site, they show some stuff, and that's it we can say that it was a read-only web there were zero interactions there were no things such as authentication comments and analytics it was just a one-way communication tool during this time, internet users were just consumers went to the internet to consume information than web 2.0 was born web 2.0 started forming around 2004 and it is still improving during this time, the web evolved a lot the boring read-only pages were replaced by web 2's interactivity, social connectivity and user-generated content interactivity was the main change in the web now the users not only consume the information from the web page but can also, interact and send information through the website the names like web 1, web 2 and Web 3.0 don't necessarily correlate with specific web technologies rather they explain how the web is being used for example web 2 is all about connection and coordinated effort in a web-based entertainment exchange, as you know, today we watched a lot of you tube videos like posts on Facebook or Instagram and perform a google. searches all of these are owned by centralized companies, for example, meta and Google are collecting data about us so they can serve us better content which in return would make us stay longer on their websites, so why do they do that well the answer is quite straightforward because they can make more money if we stay on their websites longer, and that brings us to the biggest problem with web2, and that is the lack of privacy and the fact that total control is in the hands of middlemen the big corporations and to discard that whole centralized system

 

     Web 3.0 comes into play Web 3.0 is also known as the centralized web, and it is the third and the latest phase of the internet web 3.0 is built on peer-to-peer networks of computers that talk to each other without middlemen all of the data in web 2 is controlled by the big tech companies such as google apple meta or Microsoft in the decentralized web, no single person or a the company owns any data or information about anyone or anything everything is completely visible and connected to the public, the whole point of web3.0 is that data is shared rather than owned, so why exactly is web3.0 better the centralized internet relies on servers that can go down at any time or they can be hacked, whereas a decentralized internet relies on a peer-to-peer network built by a community of users their interconnected devices host the internet rather than depending on a group of centralized high-powered users in short, if we had to summarize this and dump this down, we could say that web 1.0 was all about reading the content it was just about consuming web 2.0 was about reading and writing or rather about the interaction social media networks and so on but the data was owned by companies in Web 3.0 we can read data, and we can write data but we also own the data. That's the whole point now that we understand these differences, let's jump straight to the roadmap, unfortunately, at the time of recording there aren't a lot of good resources to learn web3 and blockchain technologies, and that's why I've taken the time to gather the best online videos courses and websites and put together with the best Web 3.0 and solidity the development roadmap, and the first step of our journey is that you should have web 2 skills most people make one mistake to dive straight into smart contracts without having a technical background in web development of blockchain technologies are built on top of web technologies so you can't learn web3 if you don't have a solid understanding of what web 2 is so before digging deeper into web 3.0 better understand the fundamentals of the web in general if you're building blockchain applications you'll need to create web apps that will talk to these smart contracts, so all of this is interconnected your web 2 skills like react next GS or just basic JavaScript will be hugely beneficial because you'll have to connect your decentralized applications to your regular web apps if you're new to web technologies in general below this article, there's going to be a link to another roadmap but this time teaching you the basics of the web once you have the basics down,

 

     We can move to our second step, which is to learn the fundamentals of blockchain as a web3 developer, you need to understand what is blockchain, how does it works, and why do we even use it? You need to understand the main point of why blockchain even exists, and you need to learn the core fundamentals, so a blockchain is an organization of PCs associated somehow or another, and they altogether run what is known as a blockchain client let me explain this in simpler terms blockchain is a chain of blocks these blocks are linked together using cryptography the chain of blocks can be considered a distributed digital ledger each block contains a cryptographic hash of the previous block, a timestamp and transaction data blockchain technology is not only related to crypto coins to learn and master the basics of blockchain technology, first we need to learn the fundamentals we need to learn the foundations of the blockchain and how the blockchain technology works we need to learn how to interact with the blockchain, we also need to gain an understanding of the tools we can use on the Ethereum blockchain we need to learn how to connect a web application to the blockchain, how to create smart contracts and decentralized applications and finally, how to deploy and test Ethereum networks we're going to talk about all of these. Topics in this article. I know this is a lot but don't worry, and we're going to talk about all of these topics in this article. also, additional materials, courses, lectures, videos, and articles are going to be Linkin in the future; in the roadmap there, you'll be able to find additional resources that you can practice your knowledge on; now, there are many different blockchains there isn't just one, for example, the Ethereum blockchain is the recommended blockchain to start with one of the best reasons to start on the Ethereum blockchain is that there is a. A lot of technical support for it. The developer team offers a great community. support, so if you're deciding which blockchain client to start with, Ethereum blockchain is the answer the third step in our journey is to learn about smart contracts a smart contract is software stored on a blockchain-based platform that automatically executes an agreement smart contracts are how you can program the blockchain to perform a specific set of instructions like you're telling the blockchain exactly what to do smart contracts enable you to exchange anything of value while also eliminating the middleman the self-executing feature of a smart a contract is what makes it very important but you might think that this can also be done in web 2. it's just a Self-executing piece of code.

 

     Why do we even need smart contracts and the answer is that the code in web 2 can easily be manipulated smart contracts are self-verifying self-executing and tamper-resistant the smart-contract code can't be changed which in technical terms means that it are immutable smart contracts could be used for banking insurance copyright and In many other sectors, smart contracts are robust they can do everything from creating your own NFTS crypto currencies and handling the back end of decentralized applications IBM had a great definition of smart contract, so here it is smart contracts are simply programs stored on a blockchain that runs when predetermined conditions are met they are typically used to automate an agreement's execution so that all participants can be immediately sure of the outcome without any intermediary's involvement or time lost, as you can see they are incredibly efficient and fair to all sides of the agreement, if you want to dive deeper into learning about smart contracts, I suggest learning about the basics of the life cycle of the smart contract and how we can interact with smart contracts using web3.0 js oh, and by the way, I'm creating a JavaScript mastery pro course where I'll teach you how to build an NFT marketplace application there we're going to create our own smart contracts in solidity from scratch the course is not yet out after quite some time of the release date, it is possible that the course is out so but if it's not, stay tuned It's coming soon. The fourth step in our Web 3.0 journey is to learn solidity.

 

     Knowing how to write smart contracts is essential in every single blockchain application, so which programming language can we use to write smart contracts? The solidity, of course; there are some other programming languages as well but don't worry because learning solidity doesn't mean that you are restricted to the Ethereum blockchain only; it will serve you well on other blockchains solidity is the primary programming language for writing smart contracts for the Ethereum blockchain, so understanding solidity is crucial solidity is also a relatively new programming language. It's a combination of a few languages. The creators of solidity got inspired by JavaScript java crust and many of their languages, making solidity amazingly versatile and intuitive as you start to write solid code. It is similar to JavaScript; it will make sense almost as if it is written in pure English, so don't think that you have to learn a whole new language from scratch. Hopefully, it's going to make sense immediately. Here is a small code sample of a solidity programming language. We're defining a Smart-contract called hello world, as you can see here. It has just one function, which is public and simply returns a string of hello contracts this is a really simple example, but if you want to learn more about the syntax of solidity, I'd highly recommend checking out the solidity cheat sheet down below the fifth step in our journey is compiling testing, and deploying smart contracts that is an essential part because as we know once the smart contracts are deployed, they are immutable, so it is important to test them out before deploying for testing, there are three different testing libraries, I recommend mocha chai and ganache and once you test these out, you're ready to deploy them and for deployment purposes,

 

     I would recommend a hard hat infra or truffle once you're smart contracts are deployed, you are ready to move to the sixth step, and that is to learn more about these centralized applications once you build and deploy your smart contracts, you'll need to create a the friendly user interface at the front end so that any user can use it to remember earlier, when I said that you should have web 2 skills before starting with blockchain development, well, that is it but what even is a decentralized application well, in simple words, apps or decentralized applications are just applications that run on a blockchain they are decentralized; they are free from the control and interference of a single authority they keep users' data out of the hands of these organizations just like crypto currency is decentralized money apps are decentralized applications a decentralized application can be a mobile or a web app in the current state of Web 3.0 it's mostly a web app though the apps can cover various use cases such as social media apps were no big company is taking the user's data, such as e-commerce for payments or even banking, for example, in a decentralized social media applications a person can post an image on the blockchain, and when the image is published; no one can delete that image, not even the owner or the creator of the social media application that's the power of the decentralized web the web app is usually just like your regular web application with HTML CSS and JavaScript but when building a decentralized application, there are two additional tasks the integration with the blockchain and the integration with the wallet, so for that you can use a JavaScript library called web3js which is helpful and easy to use the alternative to using web3js would be to connect your smart contracts manually which is a bit more work but is also doable now that you know what the apps are we can move to the seventh step, which is to learn about metalmark or any other crypto wallet blockchain wallets help people exchange funds quickly transactions are incredibly secure as they are cryptographically signed a wallet is used to interact with the blockchain using a wallet is similar to sending or receiving money through PayPal or any other payment gateways,

 

     But you use crypto currency instead there are a lot of crypto wallets out there but my recommendation would be first, to learn how to integrate your smart contracts with meta mask wallet and then later learn about all the other ones meta mask allow users to access their Ethereum wallet through a browser extension or a mobile app that can be used to interact with decentralized applications now that you learned about blockchain smart contracts and wallets you are ready to learn web3js andether.js to connect your decentralized application as we mentioned before you'll need to connect your front-end application and your blockchain smart contract the two popular choices that implement the Ethereum API are web3jsand ethersweb3js is a collection of libraries that allow you to connect with a local or remote Ethereum node using HTTP web sockets and all other communicationprotocolsether.js is a lightweight JavaScript the library that connects your JavaScript front-end with smart contracts and essentially is an alternative to web3jsboth of these libraries are excellent choices the next step is to practice your skills by building a blockchain application after learning the theory, you should get your hands dirty with the technologies we've just mentioned practice  to keep learning effectively, you have to challenge your capabilities take up a project well beyond your capabilities and stick to that project until you complete it by the end of just four to five such assignments, you'll be more proficient than most other developers in the field once again, if you've read this article after the release, it's possible that my. No marketplace application is now out. that would be the best way to start yourweb3 journey from scratch to building an amazing huge NFT market place that implements smart contracts blockchain development from scratch all the way to deployment Mark your calendar because I'll keep posting about it once it's out, and the last step is to build your portfolio when you're comfortable working with blockchain and decentralized applications you should consider building your portfolio because a portfolio website shows evidence and the expertise of your field it can also help build trust with clients because they have direct evidence of the quality of your work a portfolio is crucial if you're looking for a blockchain-related job so once again, in the guide, you'll have a lot of different portfolios blockchain project ideas that you can start implementing right away with that said,

 

     This was just a short introduction to everything that Web 3.0 has to offer of course, I couldn't cover everything in this article, but as I've mentioned, I've tried to include as many resources as possible, there you'll be able to find many other courses lectures about web3.0, thank you so much.

What is the web 3.0 or Metaverse?

 

What is the web 3.0 or Metaverse?

If you've seen the sci-fi movie The Matrix, you might be familiar with the concept of virtual reality in the form of the Metaverse, which consists of a myriad of worlds where people can interact and play games with each other and share ideas. But why have we only heard about it and not experienced it yet? This article explains what web 3.0 or the Metaverse is and why we should expect to see it soon!

 

The internet as we know it today

Web 1.0 was all about – computers linked together to share information and collaborate on projects that involved mainly text and spreadsheet files; not much else besides HTML and some basic programming language knowledge (for those who wanted to do it themselves). The 90s was when search engines began popping up everywhere, along with ways to send messages through email, chat programs, etc. In recent years, we've seen how social media has taken over – creating entire virtual communities of people who have never met face-to-face but feel like they know each other quite well.

 

Blockchain technology

The Blockchain is a digital ledger technology that almost any kind of data – representing financial records, legal contracts and intellectual property, among many other things – in a safe, secure and transparent way. Blockchains' decentralized (or distributed) nature makes them resistant to data modification. And blockchain technologies also enable smart contracts, where rules are programmed into digital agreements to execute automatically when certain conditions are met. These rules could represent anything from payments to transferring ownership rights in physical assets like cars and houses . . . It essentially allows for greater transparency and trust in business transactions.

 

How to understand Blockchain

There are many articles on Blockchain, but there is not enough clarity about what it does and how it works. Though its origins lie in providing an official bitcoin transaction database, an immutable ledger for recording transactions for all time, Blockchain has come to mean so much more than that today, with dozens of organizations developing variants of it across industries from finance to logistics to entertainment. Blockchain technology can be permissioned (private) and permissionless (public). You could think of permissioned blockchains as a list of records locked behind a firewall which everyone in your organization can see. Still, only authorized people can change or add to that list, just like today's traditional corporate databases.

 

The future of decentralization

The Internet and World Wide Web have evolved significantly over time, but despite all their changes, one thing hasn't changed at all: centralization. In fact, as of 2016, it can be argued that centralization has never been stronger due to market trends and censorship efforts worldwide. For example, with more countries regulating content individually, traditional applications like Facebook, Google and YouTube are now blocked in China — a country with 1 billion active internet users (20% of global internet users). More than just censoring certain pieces of information, though, centralization can lead to abuse of power with unprecedented control over information flows and monetary transactions within a country or globally.
