Now it has been changing faster than ever. Only 20 years ago the world got introduced to mobile phones. Within just ten years the world got addicted to it. You cannot even imagine a world with the internet and smart devices these days. Maybe lately, you have been buzzed with this term Web 3.0 blockchain stack. Today we will tell you everything on Web 3.0 blockchain stack and why it matters! The world took a big leap when the e-mails got replaced with chats and emoji. But that was also ten years back. The world is hungry for new things. While everything around you started changing, the very internet grew up. It started with raw skeletons of websites made with basic HTML. Sooner websites got smarter and became interactive. Only time can tell how smart the internet will be in the era of Web3 blockchain stack. Make yourself a hot cup of coffee. It's going to be a long and detailed to read. Web 3.0 IT stack is still not developed yet completely. But it's about to come out with full-on actions. So, what is Web 3? While Web 1.0 and 2.0 had centralized servers and, Web 3.0 blockchain stack has a decentralized network which more user-centric. A transparent and secured internet that focuses on making things more humane. There are five major significant features of Web 3.0 blockchain stack. We think these will help you to grasp the whole concept better. We are using a term these days a lot to define a device that can connect and use internet – smart. We are now surrounded by these smart devices. Are you wondering – how so? Well, take a moment and look around you. There are smart fridges, people are using home assistants like Alexa and Google Assistant, your smartphones, and tabs.
So I wanted to start building to get a sense of what the development experience felt like. And I wanted to get an understanding of the types of apps that we can build today. I dove right in and decided to document some of the things I was doing in a couple of blog posts. How to Get Into Ethereum, Crypto, and Web3 as a Developer – This is an introduction to the space in general, coming from a developer, for developers looking to break into the industry. The Complete Guide to Full Stack Ethereum Development – This is a tutorial that teaches you how to build out your first dapp. The Complete Guide to Full Stack Solana Development with React, Anchor, Rust, and Phantom - This guide dives into Solana to show you how to build a full stack dapp.
Shodan is a search engine for devices connected to the internet. It is not the same as popular search engines like Google or Bing; these common search engines focus on the content of a website exposed to the public internet. Shodan scans ports on internet-connected devices to enable searches for specific types of devices -- such as IoT surveillance cameras or network-attached storage (NAS) devices -- and searches for specific network services that are accessible on internet-connected devices. For example, Shodan can be used to search for a particular type of NAS that accepts Telnet session requests or an IoT baby monitor that enables remote access to its file system. With Shodan, a user can search for specific services running on a host.
The Internet era started in 1969. A family tree of the Internet is shown in Figure 1.1. The key driver for the Internet protocol (IP)-based network is a common application and service environment across multiple types of networks. In fact, the IP has created an open platform for innovative, flexible, and fast service creation, has enabled existing services to be supported, and has provided IP-based mobility for all types of wired and wireless transport in both the access network and the core network. The target setting is to (1) create a world class all-IP system with rapid time-to-market and future-proof design, (2) enable flexibility for providing new, revolutionary services while ensuring smooth network evolution and service continuity, (3) provide access independent design for globally seamless services, and (4) enable growth of revenue-generating systems now by leveraging the newly emerged wireless data market. The basic concept of wireless IP is shown in Figure 1.2.
