Web 3 Development: Future Awaits!

Web 3.0 is the next generation of the Internet. It is intended to be a space where websites and applications will process information in an intelligent, human-like way. This will be helped by machine learning (ML), Big Data and decentralized ledger technology (DLT)


The possibility of access through various channels on various devices.


Created by developer communities using open-source digital tools.


Protecting users' data and privacy without mediators.


Enabling various operations to be carried out by each user.


It is the ability to unify economies, avatars and systems virtual worlds.

These are working principles without which the transformation of the Internet will not take place. Is there a place for you and your business? Let's find out!

Web 3 Development VS. Web Development: Is There A Difference?

Web 3.0 is the result of several technologies converging to create a large, rich 3D world. However, this new world is not being created by the Big Bang, but by actively working developers. Is the way of programming different from standard Web development? Both yes and no.

Trustless, permissionless and decentralized Internet

The basic premise of Web 3.0 is decentralization. While in our present network, computers use the HTTP protocol to connect to the right address, in Web 3.0 information will be found based on its content, so it will be stored in multiple places simultaneously. Thus the term: decentralized Internet. Also Web 3.0 will also be trustless and permissionless (meaning that anyone can participate without authorization from a governing body). Applications will run on blockchains or decentralized peer-to-peer networks – they are referred to as DApps (decentralized apps).

Challenges for developers

Web 3.0 developers need to specialize in areas that involve data decentralization and changing data authorization. They should have experience in all aspects of web development. Have knowledge of web application design and development, but also understand the technologies that support decentralized applications. Developers will need to fully understand how blockchain works and what architecture it is based on. In addition, they have to be well versed in concepts such as consensus, hash functions, distributed ledgers, smart contracts and any other concepts integral to understanding blockchain's inner workings. Further, they should have a firm grasp in cryptographic concepts and practices, including wallets, keys and digital signatures.

Speaking the language of the Web 3.0

Computer science changes every day, but there are some standards that are always maintained, such as programming languages. To join the virtual world you need to be able to code it. Enclose in characters the value you want to share with other users. Each software developer should therefore be familiar with the programming languages commonly used to build blockchain and smart contracts. Web 3.0 programming languages can be divided into two types: those that have been used in programming for years and those created specifically for the new Web. „Standard languages” that work well for developers to code blockchain networks, decentralized applications and to create smart contracts are form example: C++, C#, Java, JavaScript framework or Python. Of the languages developed for Web 3.0, it is worth mentioning:


An object-oriented language for implementing smart contracts on various blockchain platforms, in particular Ethereum.


A multi-paradigm programming language that powers fast and scalable Web applications thanks to improved memory performance and support for several IDEs.


An open and scalable blockchain language, with a very simple and secure way for developers to write concurrent code.


A blockchain programming language designed as an alternative to Bitcoin scripting.


A contract-oriented, Python programming language that targets the Ethereum Virtual Machine (EVM).

Blockchain Data: Doing The Math

Blockchain technology is pure math. It is a shared, immutable ledger that facilitates the process of recording transactions and tracking tangible or intangible assets in a business network.

Blockchain: how does it work?

Each transaction is recorded as a „block” of data. Speeding the transactions is easy with setting a smart contract – set of rules, stored on the blockchain and executed automatically. Each block is securely connected to the ones before and after it, forming an irreversible chain of data. No one, not even a system administrator, can delete a transaction. Also each additional block strengthens the verification of the previous block and this renders the blockchain tamper-evident, delivering the key strength of immutability. Confidential blockchain records are shared only with network members given specifically granted access. Speeding the transactions is easy with setting a smart contract – set of rules, stored on the blockchain and executed automatically. There are countless blockchains, but the most popular ones, with a solid combination of technology and utility are for example: Ethereum blockchain (original smart contract platform), Solana Blockchain, NEAR or Cosmos (an ecosystem of interoperate blockchains).

Blockchain developer: responsibilities

There are many roles and responsibilities for a blockchain developer, depending whether he is a core blockchain or blockchain software developer. Core blockchain developer is concerned primarily with the blockchain network and its underlying architecture. He is: researching, analyzing and designing blockchain networks; planning security and compliance across the entire blockchain network; applying cryptographic mechanisms; developing, testing, monitoring and maintaining a blockchain network. Blockchain software developer is creating decentralized applications and smart contracts to run on a blockchain network. He might be responsible for both front-end and back-end development, as well as API development that supports blockchain integrations.

Smart Contracts: What's So Smart About Them?

Smart contracts are self-executing sets of rules that enable two parties to exchange goods and services without an intermediary. Think of them as of pieces of code that reside on the blockchain. Smart contracts are a staple of blockchain implementations. They work within the blockchain and are immutable. Smart contract would nearly do everything, from fungible and non-fungible tokens to the backend of decentralized application. Developers write smart contracts in many programming languages. For example in mentioned Solidity, which helps to create self-executing code that powers blockchain DApps.

UIG Studio: Access The Web 3.0

Web 3.0 is attracting new users and many businesses. Every blockchain based platform has a chance to emerge, because the Web does not yet have a rigid structure. And it will never have one, since the project has been talked about as a fluid, boundless creation since its inception.

So how to get there?

Should you paste the following code „LET ME IN” into your terminal window to get access? Before you sell your new token on your first DApp, you should make sure your developers have done everything right. That your project is properly prepared in terms of technology, and that the client side looks attractive. Can you tell if your decentralized application will stay up to date for long? Do you know what tools to use to ensure data security on your new social web? Are you sure that your smart contract runs smoothly?
