In this article, you will learn about what Web 3.0 is and its various aspects.

What is Web 3.0?

Web 3.0 or Web3 is the next generation of the internet which is new, improved, and based on blockchain technologies. It will also use the technologies like AI, ML, and DLT that make it more powerful. Web 3.0 is the latest phase of Internet evolution, which is fully based on developing a free ecosystem where there will be no single authority. It will change the internet world by leveraging the power of ML, AI, and emerging technologies like blockchain. The use of blockchain technology will change the way we use the internet now.

Further, Web 3.0 is also considered the third generation in the evolution of the internet, marked by decentralization and AI. Web3 allows users to connect in private or public securely. It ensures that no personal data will be exposed to third parties, which can endanger them. So, it offers easy participation without any authority.

Why is Web 3.0 important?

Web 3.0 is a budding technology in its development stage, but it is essential for businesses. It streamlines the operations of businesses by eliminating intermediaries. Web3 connects computers and users directly. Moreover, Web 3.0 applies to environments like Metaverse, Blockchain-based gaming, DeFi, etc. Further, Web 3.0 uses ML, AI, NLP, and Blockchain tech stack to offer users smart apps.

Web3 offers many opportunities to users that help to customize many web products and services based on their needs. It will help companies to maintain a better balance between their privacy and realization. Also, it offers a great framework to Metaverse, a virtual 3D world that allows developing “avatars,” digital portraits of people, to interact and develop business virtually. It is not present now but will likely exist, relying on Blockchain technology.

This way, Web 3.0 will develop the latest features and change the internet’s future.

Decentralization

The earlier generations of the web were completely centralized regarding applications and management. But Web3 is completely decentralized as there is no authority to manage it. It will deliver applications and services based distributed system.

Blockchain Technology

Blockchain plays a great role in Web 3.0. It enables distributed services and apps where data is distributed across the web through peer-to-peer networks. Moreover, it allows an immutable ledger through which transaction processing becomes highly secure and safe. Also, it develops trust over blockchain users through verification.

Machine Learning and AI

Web 3.0 will also use ML and AI technologies that imitate human intelligence using data and algorithms. It will learn from the past and data and improve itself. Further, in the Web 3.0 world, computer devices can follow information like humans using technologies like the Semantic Web and NLP (natural language processing). Hence, these capabilities of computers will allow them to generate results much faster and more relevantly. It will be helpful in the areas of medical and other latest materials.

dApps

dApps are Decentralized Applications built on top of Blockchain technology. They use smart contracts to deliver the service. They run on a distributed network rather than on a single device. Popular examples of dApps include self-performing financial contracts, social media platforms, etc

Smart Contracts

Smart contracts are a type of dApp that is stored on a blockchain. They are executed based on some fixed conditions. In other words, smart contracts are digital agreements between entities or individuals. They are programmed to run automatically when certain conditions are met. If there is any error, then it will not execute.

Cryptocurrency

Cryptocurrencies, like Bitcoin, are digital currencies based on blockchain, which differs from traditional fiat cash. It is a digital currency that uses cryptography, which is highly secure and impossible to alter in any condition and is highly secure.

Metaverse

It is another example of Web3. Metaverse is a network of shared virtual worlds and an AR (Augmented Reality) platform that allows users to connect with others, play, work, shop, etc. It gives an interactive experience to the users integrating the real world with the virtual environment.

Blockchain Games

Another prominent example of Web 3.0 technology is blockchain games. These games will provide the flexibility to the players to transfer the in-game objects digitally to other games.

Setup and configuration for FortiGate

Log in to your local Fortinet wifi dashboard, FortiWiFi. The first step is to set up an administrative profile. Click on ‘System’ in the left-side panel and click on ‘Administrators’. Give the username, type, enable ‘Restrict login to trusted hosts’ option, and click on ‘OK’. Click on ‘Network’ in the left-side panel and click on ‘Interfaces’. You can find all your interfaces on this screen. Check if your interfaces have alias names and proper administrative access.

We have to create a static route for the Internet service provider (ISP). Click on ‘Static Routes’ under ‘Network’ in the left-side menu. Click on ‘Create New’ and fill the fields of destination, gateway, interface, and click on ‘Ok’. Click on the ‘IPv4 Policy’ under ‘Policy and Objects’ in the left-side menu. Click on ‘Create New’ and give the name. The incoming interface will be your LAN, and the outgoing interface will be WAN. Add ‘all’ option for both source and destination. Adding an ‘all’ option indicates that any type of device, server, or application is allowed. Select the ‘all’ option for the service field too. Cross-check the other fields and click on ‘Ok’.

Click on ‘System Events’ under ‘Log and Report’ in the left-side menu. Whenever traffic comes in or goes out, or when admin logs in to the interfaces, all these events will be logged here. 

Troubleshooting FortiGate

If your FortiGate is not functioning as expected, go through the below steps to check all the cases,

  • Check the FortiGate LEDs – troubleshoot the LEDs on the faceplate of your FortiGate.
  • Ping the FortiGate – Ensure that ping is enabled on the FortiGate interface. Try and ping from a system on the internal network.
  • Check the FortiGate interface configurations – check the configuration to see whether the correct Addressing Mode is in use or not.
  • Verify the security policy configuration – check if the ‘Action’ is on ‘Accept’ or not in the internet access policy.
  • Verify the static routing configuration – make sure the default gateway IP address is configured and check if the ping to it is working or not.
  • Verify the DNS configuration – FortiGate uses DNS for mapping websites to IP addresses. Ping one domain and check if the name is associated with it or not.
