Popular protocols in the Web 3 space include Ethereum, EOS, and TRON. Developers also use various tools such as Solidity (the programming language for Ethereum) and Truffle (a development environment for Ethereum). Additionally, there are various platforms such as OpenZeppelin and Gnosis that provide pre-built smart contract templates and libraries for developers to use.\u003c/p\u003e\n\u003ch2 id=\"web-3-use-cases\"\u003eWeb 3 Use Cases:\u003c/h2\u003e\n\u003cp\u003eWeb 3 technology is already being used in various industries, from finance to gaming. In finance, decentralized finance (DeFi) platforms are being built on Web 3, allowing for peer-to-peer financial transactions without the need for intermediaries.\u003c/p\u003e\n\u003cp\u003eIn gaming, dApps are being created that allow players to own and trade in-game assets, creating a new form of gaming economy. In addition to these examples, Web 3 also has potential in industries such as supply chain management, real estate, and voting systems.\u003c/p\u003e\n\u003cp\u003eConclusion: Web 3 represents a significant shift in the way we interact with technology and the digital world.

It\u0026rsquo;s mostly cryptocurrency and blockchain enthusiast developers who are mastering this new form of the web, which is destined to change the internet in ways we have yet to understand.\u003c/p\u003e\n\u003cp\u003eBefore we talk about how to hire Web3 developers, let\u0026rsquo;s talk about Web3 itself.\u003c/p\u003e\n\u003ch2 id=\"what-is-web3\"\u003e\u003cstrong\u003eWhat is Web3?\u003c/strong\u003e\u003c/h2\u003e\n\u003cp\u003eWeb3, unlike its predecessors, Web 1.0 and Web 2.0, is based on peer-to-peer (P2P) decentralized networks, such as blockchain.\u003c/p\u003e\n\u003cp\u003eBlockchain is a hallmark building block of cryptocurrency, and Web3 is a product of both. Web3 developers create apps that aren\u0026rsquo;t limited to a single cloud server but are instead distributed on a blockchain or decentralized P2P network that isn\u0026rsquo;t controlled by a central authority.\u003c/p\u003e\n\u003cp\u003eIn simpler words, Web3 is similar to how most cryptocurrencies work based on the blueprint of Bitcoin.\u003c/p\u003e\n\u003cp\u003eHow does this differ from the existing Web 2.0? While Web 2.0 is user-centric (most of the content is user-generated), Web3 has taken this approach to the next level by introducing more autonomy and keeping things more transparent and relatable. In Web3, computers are heavily involved in interpreting information on a human level.\u003c/p\u003e\n\u003cp\u003eWeb3 has many additional attributes that distinguish it from Web 2.0 — it\u0026rsquo;s verifiable, self-governing, permission-less, distributed, stateless, and has built-in payment systems (cryptocurrency).\u003c/p\u003e\n\u003cp\u003eThis lack of transparency and verification led to Web 2.0 containing too much content and information, most of which isn\u0026rsquo;t helpful for general users. Its security is also sub-par, which is why there are too many hackers today and a marked increase in identity theft and other cyber-crimes.\u003c/p\u003e\n\u003cp\u003eAny application built on Web3 would be developed and owned by the users as they help create and maintain the app, earning their stake along the way. This is just how Bitcoin operates, as miners of the currency earn Bitcoins when they facilitate transactions through computing operations.\u003c/p\u003e\n\u003cp\u003eThe apps on Web3 are called \u0026ldquo;dApps,\u0026rdquo; which is short for \u0026ldquo;decentralized applications.\u0026rdquo; You can expect to hear this term more often in the near future.\u003c/p\u003e\n\u003cp\u003eAn effective Web3 developer is one who is familiar with the concept of Web3, is proficient in the relevant programming languages, and has the right tech stack to back their development work.\u003c/p\u003e\n\u003ch2 id=\"what-tech-stack-do-web3-developers-use-skills-and-tools\"\u003e\u003cstrong\u003eWhat Tech Stack Do Web3 Developers Use: Skills and Tools\u003c/strong\u003e\u003c/h2\u003e\n\u003cp\u003eThe tech stack, or developer stack, refers to the technology or tools the developer uses and excels at. A good example is the MEAN stack, which is comprised of MongoDB, Express.js, AngularJS/Angular, and Node.js.\u003c/p\u003e\n\u003cp\u003eFor Web3, there\u0026rsquo;s a specific tech stack that the developer you\u0026rsquo;re hiring must use.\u003c/p\u003e\n\u003ch3 id=\"web3-sdksdapps\"\u003e\u003cstrong\u003eWeb3 SDKs/dApps\u003c/strong\u003e\u003c/h3\u003e\n\u003cp\u003eThe Web3 SDKs, or libraries, are essential for building any dApp. These libraries support the interaction with a blockchain, such as Ethereum, and conduct transactions.\u003c/p\u003e\n\u003cp\u003eThe most important of these SDKs are \u003ca href=\"https://web3js.readthedocs.io/en/v1.5.2/\"\u003eweb3.js\u003c/a\u003e, \u003ca href=\"https://web3py.readthedocs.io/en/stable/\"\u003eweb3.py\u003c/a\u003e, and \u003ca href=\"https://docs.ethers.io/v5/\"\u003eethers.js\u003c/a\u003e.

It holds your cryptocurrency and can be either a digital or hardware wallet. For Web3 applications, a wallet is required to facilitate transactions.\u003c/p\u003e\n\u003cp\u003eThere\u0026rsquo;s a fee for the writing operations on the blockchain, which must be drawn from the wallet. For Web3, the developer can create an ETH (ethers) wallet using any of the common languages, such as Python, JavaScript, or Ruby. Alternatively, developers can use an existing wallet platform like \u003ca href=\"https://metamask.io/\"\u003eMetaMask\u003c/a\u003e.\u003c/p\u003e\n\u003ch3 id=\"nodes\"\u003e\u003cstrong\u003eNodes\u003c/strong\u003e\u003c/h3\u003e\n\u003cp\u003eNodes make up the blockchain and retain a copy of it. These are also called Web3 providers for this reason, as the application\u0026rsquo;s connectivity with the blockchain hinges on these nodes. Without these nodes, dApp cannot communicate with the smart contracts.\u003c/p\u003e\n\u003cp\u003eThe most commonly used provider is QuickNode, which provides a global network of nodes powered by speedy operations.\u003c/p\u003e\n\u003ch3 id=\"smart-contracts\"\u003e\u003cstrong\u003eSmart Contracts\u003c/strong\u003e\u003c/h3\u003e\n\u003cp\u003eIn the crypto world, smart contracts are pieces of code that live on the blockchain.

These include artificial intelligence (AI), the internet of things (IoT), and – as we will see in this article – Web3 and blockchain.\u003c/p\u003e\n\u003cp\u003eBlockchain is best known to most people as the technology that underpins cryptocurrencies like Bitcoin. The simplest way to think of it is that it’s essentially a relatively new form of database format. Blockchains have two key features that make them different from other databases. Firstly, rather than being centrally located on a specific computer or server, they are distributed. This means they are spread across multiple computers, so no one person is in direct, overall control, and all changes have to be validated by consensus.\u003c/p\u003e\n\u003cp\u003eSecondly, they are encrypted, meaning they are effectively tamper-proof, and only people with permission can add to them or edit the data they contain.\u003c/p\u003e\n\u003cp\u003eThese two features, in combination, make blockchain ideal for applications where data needs to be added, checked, and validated by multiple parties, and security and integrity are of utmost importance. A good demonstration of its robustness can be seen in the fact that the Bitcoin network itself handles \u003ca href=\"https://explodingtopics.com/blog/blockchain-stats\"\u003e\u003cstrong\u003e270 million transactions\u003c/strong\u003e\u003c/a\u003e every day, is worth (as of writing) around $400 billion, and has remained secure throughout the 13 years of its existence so far.\u003c/p\u003e\n\u003cp\u003eThese features make blockchain an attractive technology for global organizations like Shell, which need hyper-secure, scalable technology solutions to drive a new generation of applications involving collecting and sharing valuable data. Their “trustless” nature improves the current processes used across the industry, helps to reimagine energy value chains via tokenizing energy to create transparency \u0026amp; traceability, and makes new markets and new business models with DEFI / DAO\u0026rsquo;s / NFT\u0026rsquo;s, etc.\u003c/p\u003e\n\u003cp\u003eRecently, I was joined by Dan Jeavons, VP of Computational Science and Digital Innovation at Shell, as well as Shell’s blockchain lead, Sabine Brink, to discuss some of these projects on my webinar.\u003c/p\u003e\n\u003cp\u003eBrink tells me, \u0026ldquo;The intersection of digital and energy is one of the most exciting spaces. Looking at how we utilize this technology – web3, a blockchain that accelerates the energy transition. This is an extremely motivating journey to be on.”\u003c/p\u003e\n\u003cp\u003eThis enthusiasm has led to her spending the past five years examining every area of the business where blockchain and related Web3 technologies could be implemented in order to drive sustainability and green energy goals. A number of projects have emerged out of this, and the most promising are now moving into pilot and production stages, where it is hoped their ability to drive real global change will be realized.\u003c/p\u003e\n\u003cp\u003eIn particular, I was interested to hear how the energy giant is using blockchain to trace and verify the provenance of energy created from renewable sources. As the world has come to appreciate the urgent need to transition towards sustainable energy sources, huge rewards – both in terms of financial incentives and customer loyalty – have emerged for organizations that work towards affecting change. The process, however, is often opaque – it’s difficult for customers or partner organizations to really be sure exactly how clean a specific energy source or supplier is.\u003c/p\u003e\n\u003cp\u003eJeavons and Brink explained that Shell had developed a blockchain-based system that can demystify the complex web of sources.\u003c/p\u003e\n\u003cp\u003eHe says, “So if you look at the electricity market today, we have energy attribute certificates (EAC) that represent green energy or grey [non-green] energy generated in a given month or year. For companies that aim to run on 100 percent green energy, their monthly or yearly certificates may match their total energy consumption, but when the sun doesn\u0026rsquo;t shine, and the wind does not blow, grey energy is actually being consumed. So it’s hard to claim that they are actually consuming green energy on a 24/7 basis.”\u003c/p\u003e\n\u003cp\u003eShell’s solution involves creating highly granular certificates in real-time at the source where the energy is created – which could be solar panels in the desert or wind farms in the ocean - to represent the green energy produced at every half hour, in sync with established energy attribute certificates systems. Every point of that electron’s journey to the point that it is consumed is tracked and recorded on a blockchain.\u003c/p\u003e\n\u003cp\u003e\u0026ldquo;This is one of those solutions where blockchain creates the transparency and assures us there\u0026rsquo;s no double-counting of electrons in the system; we believe this could be a game-changer,” Jeavons tells me.\u003c/p\u003e\n\u003cp\u003eAnother project which has just made the leap to the \u003ca href=\"https://www.shell.com/business-customers/aviation/news-and-media-releases/news-and-media-2022/shell-accenture-and-amex-gbt-launch-one-of-the-worlds-first-blockchain-powered-digital-book-and-claim-solutions-for-scaling-sustainable-aviation-fuel-saf.html\"\u003e\u003cstrong\u003epilot phase\u003c/strong\u003e\u003c/a\u003e is an ambitious venture between Shell, Accenture, and American Express Global Business Travel (Amex GBT) aimed at increasing the availability and use of sustainable aviation fuel (SAF).\u003c/p\u003e\n\u003cp\u003eBrink says, \u0026ldquo;To me, this is one of the most exciting projects we\u0026rsquo;ve been working on. I’m very proud of the team. It’s one of the first public blockchain solutions that creates a credible and transparent way to help decarbonize the aviation sector. Thanks to its inherent technical features, blockchain offers verifiability, transparency, and security of environmental attributes of SAF.”\u003c/p\u003e\n\u003cp\u003eThe product is Avelia – one of the first blockchain-powered book-and-claim systems which will offer around one million gallons of sustainable aviation fuel (SAF) and associated environmental benefits to corporates looking to reduce emissions from their business travel.\u003c/p\u003e\n\u003cp\u003eCurrently, there is insufficient SAF available at an affordable price. It’s hoped that through aggregating demand for SAF among corporate travelers who form a more concentrated segment than leisure passengers, there will be a reduction in the price – with SAF currently priced significantly higher than equivalent conventional aviation fuels. However, growth in demand for the fuel will theoretically lead to suppliers increasing investment in production and, therefore, an eventual fall in price.\u003c/p\u003e\n\u003cp\u003e“It’s really hard to decarbonize the aviation sector,” Brink tells me. “Decarbonizing the aviation sector cannot happen overnight. Today we do not have large-scale airplanes that can be powered by green electricity that are able to travel the world. Sustainable aviation fuel is actually a solution – sustainable aviation fuel that we can utilize today and implement with existing infrastructure. With Avelia, we hope to demonstrate that the tracking of SAF data at scale can be delivered in a credible manner, thereby proving to decision-makers that a mechanism for corporations and airlines to book and claim SAF is an acceptable form of emission reduction. In turn, this creates increased demand signals to structurally scale the SAF production required to reduce emissions in aviation.\u0026rdquo;\u003c/p\u003e\n\u003cp\u003eOther blockchains and digital transformation projects currently undergoing evaluation or pilot status at Shell involve “digital passports” to track the lifecycle of industrial parts, equipment, and machinery at energy plants operated by the company and its partners.\u003c/p\u003e\n\u003cp\u003eOf course, all of this technology-driven transformation is driven, at its root, by data, and Shell has worked to implement an integrated data platform that aggregates 2.9 trillion rows of information harvested from all areas of its business. This includes IoT sensors installed across its plants and wind and solar farms, ultimately allowing it to create \u003ca href=\"https://bernardmarr.com/7-amazing-examples-of-digital-twin-technology-in-practice/\"\u003e\u003cstrong\u003edigital twin\u003c/strong\u003e\u003c/a\u003e applications to help it better understand the operation of its assets.\u003c/p\u003e\n\u003cp\u003eJeavons says, \u0026ldquo;This is what my team is so excited about – the potential to do this at scale. We\u0026rsquo;re rolling out digital twin … we’re rolling out AI … and when you put that together with traceability, we believe we could bring to market a whole raft of decarbonization solutions … where we could partner with our customers to help them accelerate their own decarbonization journeys.

The idea behind using AI comes from the goal of providing faster, more relevant data to end-users. A website using AI should be able to filter through and provide the data it thinks a specific user will find appropriate. Social bookmarking as a search engine can provide better results than Google since the results are websites that have been voted on by users. However, these results can also be manipulated by humans. AI could be used to separate the legitimate results from the falsified, therefore producing results similar to social bookmarking and social media, but without bad feedback.\u003c/p\u003e\n\u003cp\u003eAn artificially intelligent web will also introduce virtual assistants, an element that is already emerging today as an aspect built into a device or through third-party apps.\u003c/p\u003e\n\u003cp\u003eThe idea behind the semantic web is to categorize and store information in a way that helps teach a system what specific data means. In other words, a website should be able to understand words put in search queries the same way a human would, enabling it to generate and share better content. This system will also use AI; semantic web will teach a computer what the data means and then AI will take the information and use it.\u003c/p\u003e\n\u003cp\u003eUbiquitous computing refers to embedded processing in everyday objects, which enables the intercommunication of devices in a user’s environment. This is thought to be another property that Web 3.0 will have. The concept is similar to the Internet of Things.\u003c/p\u003e\n\u003cp\u003eThe technologies which will make up these properties include microformats, data mining, natural language search, and machine learning. Web 3.0 will also be more focused on peer-to-peer (P2P) technologies such as blockchain. Other technologies such as open APIs, data formats, and open-sourced software may also be used while developing Web 3.0 applications.\u003c/p\u003e\n\u003ch3 id=\"web-30-and-web-20\"\u003eWeb 3.0 and Web 2.0\u003c/h3\u003e\n\u003cp\u003eWeb 2.0 refers to websites and applications that utilize user-generated content for end-users. Web 2.0 is used in many websites today, chiefly focusing on user interactivity and collaboration. Web 2.0 also focused on providing more universal network connectivity and communication channels. The difference between Web 2.0 and 3.0 is that Web 3.0 is more focused on the use of technologies like machine learning and AI to provide relevant content for each user instead of just the content other end users have provided. Web 2.0 essentially allows users to contribute and sometimes collaborate on-site content, while Web 3.0 will most likely turn these jobs over to the semantic web and AI technologies.\u003c/p\u003e\n","date_published":"2021-11-25T10:24:00+03:00","image":"https://ajulu.netlify.app/images/1_xdx6fonpgn2sq0fnmdqh8w.jpeg","tags":["web3","decentralized web","decentralized"]}]}
