What is a Web3 developer?

A Web3 app developer is a software developer who specializes in creating decentralized apps (dApps) that run on the blockchain.

Web3 is a term used to describe the third iteration of the internet, which is focused on decentralized applications (dApps) that run on the blockchain.

The first iteration of the internet was focused on static web pages, while the second iteration was focused on the creation of dynamic, interactive web applications.

Web3, on the other hand, is focused on building decentralized applications that operate on a peer-to-peer network and are powered by blockchain technology.

We’ve detailed the different types below:

  • Web3 frontend developers: These specialize in developing user interfaces and front-end components for decentralized applications (dApps).
  • Blockchain developers: Responsible for building and maintaining the blockchain infrastructure of a Web3 project.
  • Smart contract developers: These specialize in writing, testing, and deploying smart contracts on various blockchain platforms.
  • Web3 backend developers: Responsible for developing and maintaining the back-end infrastructure of a Web3 project, including databases, servers, and APIs.
  • Dapp developers: These specialize in developing decentralized applications (dApps) that run on blockchain platforms.

Each of these types of developers plays a critical role in building successful Web3 projects.

What are the benefits of hiring Web3 developers?

There are several benefits to hiring Web3 developers for your project, chief among them being that Web3 developers have extensive and up-to-date knowledge of the latest Web3 tech.

We’ve listed some of the key benefits below.

Transparency

Web3 technologies are based on blockchain, which is a decentralized and distributed ledger that records transactions in a transparent and immutable manner.

This means that all parties can see the same information and that the data cannot be altered or deleted without “consensus” from the network.

Data ownership

Traditionally, data ownership is centralized, with companies and organizations holding the rights to user data.

However, in the Web3 ecosystem, data ownership is often distributed among many parties, including users, developers, and other stakeholders.

Data security and privacy

Many Web3 solutions use encryption and other security technology to protect data in transit (and at rest).

This can help prevent unauthorized access and ensure that user data is kept private and secure.

Increased user interaction

Web3 technology has the potential to significantly increase user interaction by allowing for greater decentralization and transparency.

With the ability to interact directly with decentralized apps and smart contracts, users can take more control of their online activities and transactions.

How does Web3 development work?

Web3 development involves several steps that are essential in creating decentralized apps that utilize protocols such as IPFS, Filecoin, and Ethereum.

Here are the key steps involved:

  1. Understanding blockchain technology: Developers must first understand the fundamental concepts of blockchain technology, such as distributed ledger, consensus algorithms, cryptographic hashing, and smart contracts.
  2. Choosing the right protocol: Developers then need to choose the right protocol for building their decentralized application. They can pick from various decentralized protocols like IPFS, Filecoin, and Ethereum, depending on the type of app they’re building.
  3. Designing the app architecture: Once the protocol is chosen, developers must design the application architecture by identifying the different components and their functionalities.
  4. Developing smart contracts: Smart contracts are self-executing contracts that run on a blockchain. Developers must write smart contracts that define the rules and logic of the application. They must also test the smart contracts on a test network to ensure that they are working correctly.
  5. Developing the frontend: The frontend of the application is the user interface that allows users to interact with the application.
  6. Testing and deployment: Once the application is developed, developers must test it thoroughly to ensure that it’s working correctly.
  7. Maintenance and upgrades: After deploying the app, developers must maintain and upgrade it regularly. They must also fix any bugs that arise, ensuring it’s secure and scalable.

What do top Web3 companies do?

Web3 companies are those that leverage blockchain technology to create decentralized applications (dApps) that offer various services to their users.

We’ve detailed some of the key services below.

Cater to the design and development process

The design and development process of Web3 companies is unique in that it requires a deep understanding of both blockchain technology and traditional software development practices.

The first step in the process is to define the problem the Web3 company is trying to solve.

Once the problem is identified, the development team can begin to design the architecture of the dApp–this involves deciding on the blockchain platform to use, the smart contracts that will be required, and the user interface design.

Create interactive dApps

Creating interactive dApps is an essential aspect of Web3 development.

The goal of an interactive dApp is to provide users with a seamless and engaging experience that encourages them to continue using the platform.

To achieve this, Web3 companies focus on creating user-friendly interfaces and utilizing various technologies such as gamification, social interaction, and personalized experiences.

Integrate Web3 protocols and blockchain architecture

This is essentially where developers choose the blockchain technology that will be used to build the dApp.

Ethereum, for example, is one of the most popular choices, but there are other blockchain platforms such as Solana, Polkadot, and Binance Smart Chain too.
