Decentralized applications are web or mobile apps that offer the benefits and features of blockchain technology whilst being able to fulfill their primary purpose. 

Since the emergence of crypto and the development of wider blockchains, decentralized apps have become a pivotal aspect of the experience and ultimately have given the whole of Web3 new use cases otherwise not achievable.

Over the years the scalability of Decentralized Application (dApps) has become astronomical with some of them hitting the mainstream due to their accessibility and credibility. As the masses are looked to be onboarded, decentralized applications will play a pivotal role across many different industries and use cases in doing so.

In this guide, we'll delve into the concept of decentralized applications, explore their various types, examine the underlying blockchains that support them, and evaluate their pros and cons.

‍

What are Decentralized Applications?

Decentralized applications , commonly referred to as dApps, are software applications that operate on a decentralized network rather than a centralized server. 

Unlike traditional applications, which are controlled by a single entity or organization, dApps leverage blockchain technology to distribute data and computational resources across a network of nodes, ensuring transparency, security, and censorship resistance.

Decentralized apps can be accessed across many different devices such as mobile and desktop and as they develop are becoming more and more prevalent in everyday life. We are starting to see the emergence of decentralized devices such as Solana’s mobile phone.

Types of Decentralized Applications

Like normal mobile and computer apps, decentralized applications span across different industries and use cases. 

Technology makes life a lot easier and dApps are no exception to this as they bring together the power of blockchain, crypto and Web3 and are implemented into the everyday lives of users new and old!

Here are some of the main types of dApps:

‍

Financial dApps: These applications facilitate various financial services, such as lending, borrowing, trading, and yield farming, without the need for intermediaries. Applications like this are what help the world of DeFi and their services available to people on the go. Furthermore DeFi apps allow users to have more control over their finances and the potential earnings from decentralized services.

Gaming dApps: Gaming dApps offer decentralized gaming experiences, allowing users to own and trade in-game assets securely. Blockchain gaming is slowly becoming one of the staple sectors of the whole of the decentralized world thanks to the accessibility and fun factors associated with them.

Social dApps: Social decentralized aim to decentralize social media platforms, empowering users to control their data and interactions. Over the years it has become clear that social media conglomerates have monopolized the industry along with people’s data. The decentralization of social media creates an even playing field amongst providers, creators and the everyday user.

Supply Chain dApps: These applications utilize blockchain technology to enhance transparency and traceability within supply chains, mitigating fraud and improving efficiency. As the world becomes more interconnected through economics and business, decentralized supply chains will help to remove nuances for more profitability amongst businesses, and even happier consumers.

Identity dApps: Identity dApps enable users to manage and verify their digital identities securely, reducing reliance on centralized identity providers. We live in a digital age where a lot of sensitive data such as our identities are stored, such as passports, banking details etc. Identity apps therefore benefit from added security infrastructure and overall scalability presented by blockchain technology providers.

Examples of Decentralized Applications

Since we have covered the different use cases here are some examples of dApps that can be found on the blockchain. 

‍

Compound Finance: Compound is a decentralized lending protocol built on the Ethereum blockchain. Users can lend and borrow various cryptocurrencies, earning interest or paying borrowing fees based on supply and demand dynamics.

Uniswap: Uniswap is a decentralized exchange (DEX) protocol that enables users to swap ERC-20 tokens directly from their wallets. It operates using automated liquidity pools, allowing for permissionless and non-custodial trading.

Axie Infinity: Axie Infinity is a blockchain-based game where players collect, breed, and battle fantasy creatures called Axies. It features play-to-earn mechanics, enabling users to monetize their gaming skills and assets. While it has fallen from it’s all time high.

Steemit: Steemit is a decentralized social media platform where users can create and curate content, earning rewards in the form of STEEM tokens. It prioritizes user-generated content and community governance.

VeChain: VeChain is a blockchain platform specializing in supply chain management and enterprise solutions. It provides tools for product authentication, supply chain tracking and data sharing across various industries.

Blockchains Supporting Decentralized Applications

As we all know the first blockchain to emerge was Bitcoin, but it could only serve one purpose and that was to facilitate a minimum amount of transactions through the Proof of Work consensus mechanism.

Since then there have been a number of different blockchains made to create a more scalable and robust blockchain ecosystem. While the incentive of decentralization still stands, the newer chains can create and launch dApps for a number of reasons which in turn gives the blockchain more flexibility and overall utility.

These are some of the top blockchains that support decentralized applications:

‍

Ethereum: Ethereum is the leading blockchain for decentralized applications, offering a robust ecosystem and smart contract functionality. Its flexibility and developer-friendly infrastructure have fueled the growth of countless dApps.

Binance Smart Chain: Binance Smart Chain is a blockchain platform compatible with Ethereum Virtual Machine (EVM), providing high throughput and low transaction fees. It has gained popularity among developers and users alike, hosting numerous dApps.

Polygon (formerly Matic Network): Polygon is a Layer 2 scaling solution for Ethereum, enhancing its scalability and usability for decentralized applications. It offers fast and inexpensive transactions, making it attractive for dApp development.

Cardano: Cardano is a third-generation blockchain designed for scalability, interoperability, and sustainability. With its focus on security and governance, Cardano aims to support a wide range of decentralized applications in the future.

Solana: This Layer 1 blockchain has proven to be incredibly powerful in terms of scalability and throughput making it a go to for dApp developers. We have seen the likes of VISA move their blockchain efforts onto Solana’s network.
