Web3 – A Step Forward

The name Web3 is used to announce all the services that will together in the future completely reshape the Internet and the way we use it.

The third generation of the web, which is also referred to as Web 3.0, is being discussed more and more, although there is no officially accepted definition of what it represents yet since it is an emerging technology, whose potential has yet to be understood.

Based on what can already be found now, it is expected that the Web3 revolution could happen after the concept of the Internet of Things is more prevalent and Artificial Intelligence is more present in everyday life.

Therefore, Web3 refers to the internet iteration, a standard of development in the world of advanced programming, and is a model based on technology that can take advantage of interactivity, moving away, for example, the concept of keyword search and performing a smart search.

Evolution of the Web2 concept

As the name says, Web3 is an evolution of the current Web2 concept, whose functions are being expanded and adapted to the needs of users.

Unlike the online experience of today, Web3 is designed to use AI to make search smarter. The search results that appear on the top of the list due to their popularity, even when they are not an adequate response to the user’s request is something that changes with Web3. In this sense, Web3 puts search in context and uses it to filter out irrelevant information to provide a specific set of results.

It is a technical invention that should be independent, and at the same time usable on all media, or on all outputs, such as different types of screens and printers. Also, it should be universal, i.e. it should not be affected by any operating system, software, or hardware manufacturer, and should be available to everyone in accordance with W3C guidelines and open to various databases.

Because Web3 uses the internet to connect with information, the search engine we use could “read” our habits to help us get more specific search results.


Also, when it comes to digital funds, i.e. cryptocurrencies and smart contracts, in order to achieve interaction, it is necessary that transactions take place on the blockchain. For users outside the chain or software to perform transactions on the blockchain, the nodes must transfer those transactions to the core peer-to-peer network. In this sense, the connection with Ethereum nodes is simplified.

Before the introduction of Web3, there were several versions of the previous web, including the version we currently use Web 2.0, as well as the older Web 1.0, which was given that name only after version 2.0 appeared.

Web 1.0 referred to static, read-only pages, from which users could only receive information but not provide it.

Web 2.0 has enabled users to share information on the Internet, which is most easily illustrated by the emergence of social networks that have enabled communication with other users in real-time.

The IoT plays an important role in enabling Web3. In the future, a mass connection is needed for everything, and that is what is expected from the 5G network and advanced ways of data storage.

Web3 requires spatial computing because the search will require a different interface and different methods of interaction, such as sound and even potential movement.

No central entity

The Web3 version is based on blockchain technology, more precisely, on an algorithm that allows trust when exchanging with unknown users, assuming that their intentions are not malicious.

This eliminates the need to trust the central entity, such as Google, Facebook, Twitter, and other information-sharing platforms that collect user data during the process. It is a decentralized exchange of digital data and resources.

Web 3.0 has become increasingly relevant thanks to the efforts of the global blockchain community. Nodes in Ethereum provide a low-level interface for users who perform transactions, and they can be received via the JSON (JavaScript Object Notation) RPC (Remote Procedure Call) interface.

JSON RPC is a text encoding format that allows running processes to receive data. Nodes participating in the Ethereum network can expose this interface in different ways, depending on the configuration and implementation of the underlying software.


The purpose of Web3 is to make it easier for developers to access different Ethereum nodes, but also to allow access to another blockchain.

Connecting to a blockchain node allows you to view and use information, but also to set up transactions in an automated way, as well as to use smart contracts.

To be realized, it is necessary to fulfill several technical requirements, but also possibilities. The first is the existence of direct access to a particular blockchain through a node, preferably complete. The second is the use of providers, i.e. gaining access through third parties, among which Metamask is one of the most reliable. Metamask is an Ethereum wallet into which a Web3 provider object is inserted into a browser.


Before Web3.js came along, the only way we could communicate with smart contracts was through an API provided by the Ethereum node that functions as a JSON-RPC server, which was an extremely complex process.

Web3.js now allows developers to interact with the Ethereum blockchain, making it usable directly in web technologies, since JavaScript is originally supported in almost all web browsers.

Web3.js can be used to connect to the Ethereum network via any Ethereum node that allows access via HTTP.

One common way to integrate web browser applications with Ethereum is to use the Metamask browser extension in combination with Web3.js.

A Web3 provider is a data structure that provides links to publicly available Ethereum nodes, with the use of Metamask allowing users to manage private keys and sign transactions in their web browser.

Data creation

In short, Web1 referred to an exchange system in which companies created data for the benefit of companies thanks to static pages. The content created on Web2 has enabled users to generate data for the benefit of companies, i.e. consciously or unconsciously sharing information on the internet that is useful to companies for making business decisions.

The principle on which Web3 is based is not only decentralized but allows users to produce data and content for the benefit of other users.
