Web 2.0 is soon going to be replaced with its smarter sibling i.e. Web 3.0; overcoming the issues of security and privacy.\n\nInstead of insecure databases and opaque data sharing practices, Web 3.0 will return control to the users which mean they will be able to access data from anywhere; mainly being driven by cloud applications and smart-phones. Apart from security, personalization is another add-on!\n\n### What Web 3.0 brings to the table?\n\nWeb 3.0 can be rightly said as an intelligent web!\n\nIt is all about the evolution of third generation internet services that is a blend of Semantic web, Microformats, Artificial Intelligence, Data Mining, Natural Language Search and Machine Learning technologies.\n\nExperts say that Web 3.0 is a data-driven and semantic web. The user will type a query on the web; the web will understand the context and essentially will meet the needs of the user.\n\n**_So, if you perform more searches related to travel destinations, you’ll receive more ads related to the travel places. Also when you search for the cheap tickets, the search engine will keep in mind about the previous search and show you the results combining “travel destination and cheap tickets”._**\n\nSo, the next gen search engine will not only search for the matching keywords but also perform the context search based on user’s behavior and preference.\n\n#### Web 2.0 is largely about words; Web 3.0 will be the blend of words and visualization\n\nWeb 3.0 will focus more on web interaction and will:-\n\n* Limits and control users content\n* Turns web into a big database\n* Focuses on organizing data in a meaningful way\n\n### Let’s get simpler\n\n#### Web 2.0\n\nLucy wants to go for a movie and gaming zone followed by shopping and dinner in her vicinity. She will go to Google and look through a bunch of information on the web comparing timings, rate etc. which would consume much of the time.\n\n#### Web 3.0\n\nWith the help of the search engine, Lucy will be able to generate this information faster. Search Engine will provide highly accurate and recommendations in a very intelligent way based on Lucy’s profile. Lucy will get the information needed at one go and ultimately it will save much of the time.\n\nSearch Engine will learn about you and your habits from each search you perform and will gather details about your from your previous activities like likes and social postings and present the answers as per your preferences.\n\nSo, how Web 3.0 will be different from previous Web versions?\n\n### Quick Comparison: Web 1.0 vs. Web 2.0 vs. Web 3.0\n\n!(https://hackernoon.com/hn-images/1*0X5cHgW_CgElpM59sui1sQ.png)\n\n### Coming Back To Web 3.0 — Concerns of using Web 2.0\n\nAs everything on the web will be linked and the machine will save the user’s preferences, it raises the issues about security and privacy!\n\nWhen the user engages deeply and consistently, web will generate more verifiable and minable pieces of data. The more information is provided, the more they are rewarded with a richer and more dynamic experience. However there raises the question of security!\n\nSo, what would be the technology that can help to stay secure?\n\n### Blockchain Technology — Answer to the security and Privacy concerns\n\nBlockchain Technology makes it possible to store data in a secure way. With the decentralization of data, personal information will not be stored in the large data centers and databases of the companies. Rather all data will be controlled by a single company which would drastically decrease the personal data breaches.\n\n> **_Bitcoin was the opening act. That was the beginning of Web3.0._**\n\nPublic Blockchain such as Etherum provides the decentralized platform to run smart contracts and removes the middlemen enabling the individual to communicate directly. In Web 3.0, Apple, Google, Facebook to the name of few would have no control over the data of the users which would result in a high security and privacy.\n\nLet’s see what kind of platforms Web 3.0 has stored-in.\n\n### The Upcoming Platforms of Web 3.0\n\nBelow-mentioned are just examples that will be used in web 3.0 to avoid security and privacy issues.\n\n!(https://hackernoon.com/hn-images/1*rqIt50mCTLjYbabDNcXeMQ.png)\n\nIf we look at the current scenario, decentralized apps, wallets, platforms etc. that makes up web 3.0 are all scattered. To use this, there is always a need for identities, logins, OTPs etc. which disturbs the security.\n\nSo, how about using Web 3.0 to avoid privacy clutters?\n\n[Storj](https://storj.io/) is a cloud-based data storing platform that uses client-side encryption for security reasons. Data owners can trust and access their files easily. It is a decentralized network that delivers great performance, functionality and durability.\n\n[Brave](https://brave.com/) is a browser that provides unparallel privacy and security. It prevents tracking and keeps information safe and secured. It stays private on your device until you delete it.\n\nThe applications mentioned in the example are semantic and intelligent in nature which results in an improved communication.\n\n### How Web 3.0 Can Make Decentralization Possible?\n\nAs per [Wikipedia](https://en.wikipedia.org/wiki/Semantic_Web), Web 3.0 is synonymous to Semantic Web! However, with the help of Artificial intelligence and Semantics, it will help to give the meaning to the data and solve the problems. Web 3.0 is a sure shot to understand the human mind closely.\n\n### Web stack used in Developing Semantic Web 3.0\n\nFrom a technical standpoint, the Semantic Web primarily consists of three standards:\n\n#### RDF (Resource Description Framework):\n\nIt is a data modeling language where web information is stored and represented in RDF\n\n#### SPARQL (SPARQL Protocol and RDF Query Language):\n\nIt is the query language which is specifically designed to query data across various systems.\n\n#### OWL (Web Ontology Language):\n\nThis is the schema language or Knowledge Representation (KR) language which enables you to define concepts so that they can be re-used as much and as often as possible.\n\n### Advantages of having Web 3.0\n\nThere are a number of advantages that Web 3.0 offers:\n\n\\-> **No middlemen to control data:** As stated above, Etherum would provide a platform where data will be decentralized, where no entity will be able to alter the code without the permission of other entities in the network. Moreover, no one will have rights to block the websites and services.\n\n\\-> **Reduced data breaches:** Because data will be decentralized and distributed, it will be difficult for hackers to have control over the entire network. However, data cannot be erased or altered once it is in the block chain. This will create a continuous flow of accurate information and ultimately result in no data loss.\n\n\\-> **Ability to work on any gadgets:** Today, applications are OS-specific which means it runs on a single operating system. Web 3.0 will provide easy to customize and device-agnostic applications i.e. applications will run on any device which includes television, refrigerators, microwaves, sensors, smart-phones and many more devices.\n\n\\-> **Uninterrupted service:** DDoS attack will be drastically reduced! Due to the decentralized system, there will continuous data processing; no system can be blocked to stop a service; no single hardware infrastructure can hold the service. It will have multiple backups to prevent server failure.\n\n### Challenges to be considered as well\n\nWeb 3.0 has a number of things to offer which can make user’s life easier. But, as said, there is always a second side of the coin.\n\nLet’s see what pain points it brings with it:\n\n\\-> **Huge Data Set:** There is no doubt of concern that www contains billions and trillions of web pages and terminologies. Existing technology is not sufficient enough to get rid of duplicated terms. The new system will have to deal with a huge input of data and may not be able to understand the context.\n\n\\-> **Scalability:** Entrepreneurs will have to worry about how to manage the data in a scalable manner, that is, how to organize it, where to store it and how to find the right content.\n\n\\->**Visualization:** With the increase in the overloaded information, visualization will play a key role for the easy recognition of the relevant content and the purposes.\n\n### 5 Main Features That Makes Web 3.0 Super Great\n\n\\-> **Semantic Web:** Enhanced web where content is analyzed based on the meaning of words\n\n\\-> **Artificial Intelligence:** Focuses on natural language processing where computers will understand the information more like human in order to provide faster and relevant results\n\n\\-> **3D Graphics:** The Three-Dimensional design will be used in websites and services to provide a clear picture to the users. For instance: museum guides, computer games, etc.\n\n\\-> **Connectivity:** Information is connected to meta-data which helps to users to fetch accurate information\n\n\\-> **Ubiquity:** Every device around you will be connected with the web which means content will be accessible everywhere\n\n### Web 3.0 — Takeaways for Business Owners\n\n\\-> The content of superior quality must be used all throughout the Internet to provide the value of your product in the market\n\n\\-> Opt for the website with 3D graphics for a more immersive and interactive experience. It will contribute to the modern look of the website\n\n\\-> Also, opt for an easy-to-navigate website in order to provide a simple yet engaging user experience\n\n\\-> As users will be able to reach any information on the Internet from everywhere; you should consider the optimization the information on all devices (mobile, tablet or desktop)\n\n\\-> Your customers will enjoy the flow of fresh content about your product and services\n\n\\-> AI-powered assistants are making the future! Entrepreneurs must focus on creating rich digital assets ensuring that search-engine can locate and serve the content easily.\n\nIt may seem that, it will get harder to establish a presence online with a semantic web, but the use of best strategies will make you win the battle. Web 3.0 is all about making the life of the people easier where they don’t have to install and upgrade the applications; they just have to access the files instantly from anywhere.\n\n### Beyond Web 3.0 — A look in the future\n\nIt is sure that Web 3.0 will change our lives and will make it trouble-free to search anything online keeping our data secured. With the growth in the field of digital technology, Web 3.0 will be arriving soon! It’s just a matter of time before we take a leap in another era of the internet.
