Figuring out how to build a Web3 app can seem like a daunting task, especially if you're not a developer. The complexities of blockchain technology, smart contracts, and decentralized data management often create barriers for businesses looking to benefit from Web3.

We’re here to help you with a no-code web3 building approach that doesn’t require an engineering degree.

What you’ll learn in this article:

• What Web3 apps are and how they work
• Key components of Web3 apps like decentralization and smart contracts
• Step-by-step process to create a Web3 app using Blaze

What is a Web3 App?

A Web3 app, or decentralized application (dApp), is built on blockchain technology, enabling a decentralized network where data is shared across multiple nodes without the need for central control – we’ll explain those in just a moment!

This contrasts with earlier versions of the internet:

• Web 1.0: Known as the “read-only” internet, users could connect to servers and passively consume content. It was a static experience with minimal user interaction.
  
  
• Web 2.0: Introduced dynamic interaction, allowing users to create, share, and consume content via a distributed network of servers worldwide. This is the internet most people interact with today, though it still relies on centralized platforms and services.

Web3 takes it further by removing centralized control altogether. It uses blockchain technology, where data is validated and stored across a peer-to-peer network. Each transaction or action is confirmed by the collective responses of nodes in the network, ensuring security and transparency without a central authority.

While decentralization and distributed networks may seem similar, they differ in key ways:

• Decentralized networks: No central authority, with all nodes having equal control over the network.
• Distributed networks: Data is spread across multiple nodes, but there can still be centralized points of control.

Components of a Web3 App

Web3 app development relies on three essential components: decentralization, blockchain, and smart contracts. Here’s what they mean:

Decentralization:

• Data is stored across a peer-to-peer network, removing the need for third-party services.
• Every node in the network has equal power, but they can be organized in ways to enhance efficiency.
• This setup ensures users have direct control over their data without relying on a centralized entity.

Blockchain:

• Blockchain is the foundational technology behind Web3 apps, allowing secure and transparent data management.
• Data is grouped into encrypted "blocks" that are distributed across the network.
• Existing blocks must validate each new block before it is added to the chain, making the process tamper-proof and highly secure.

Smart contracts:

• These are self-executing codes embedded in the blockchain that automatically carry out actions when predetermined conditions are met.
• Smart contracts remove the need for intermediaries, ensuring that tasks happen automatically and reliably once triggered.
• For example, a smart contract can release payment to a seller once goods are delivered, without involving third-party verification.

Together, these components create a system where data and transactions are more secure, transparent, and efficient, giving users greater control over their digital interactions.

No-Code Web3 App Ideas

Web3 applications still aren’t perfect, and their decentralized structures can make it difficult for users to interact with the blockchain. Here are some web3 app development ideas anyone can try with low-code app building from Blaze.

Track New NFTs

Non-fungible tokens, or NFTs, are unique blocks on the blockchain that can be traded or sold. Unlike cryptocurrencies, NFTs cannot be replaced by other tokens of apparent equal value. Today, NFTs are better known for their use in digital art, but they also have applications that range from real estate to banking and personal identification.

One of the main challenges to trading NFTs on fintech apps today is that they exist across multiple marketplaces. You can build low-code web3 applications that bring all this data into a single interface, making trading NFTs between many marketplaces more manageable.

Marketplaces

Web3 marketplaces and fintech apps are just another way that blockchain removes the middleman, giving power over personal interactions to users in the network. The possibilities with marketplace applications are nearly endless.

Although beneficial in many ways, cutting out the intermediaries for transactions can also make them harder to interact with on the user’s end. You can create applications to help users track and interact with decentralized marketplaces, making them more convenient and easier to use.

DAO member portals

A decentralized autonomous organization, or DAO, is a group without a centralized authority. Most DAOs exist on the Ethereum blockchain and will typically use their tokens for voting power.

Create portals for DAO members to interact with the blockchain, making everything easier to use. One drawback to web3 applications is that they require more steps and education, meaning they have a higher barrier to entry.

How To Build a Web3 App Without Coding

Web3 app development might seem complex but with Blaze.tech’s no-code platform, you can develop fully functional decentralized applications (dApps) without needing any coding knowledge.

Blaze provides all the essential tools, integrations, and components to streamline the process. Here’s a step-by-step guide to creating a Web3 app without writing a single line of code:
