Understanding Decentralized Applications (dApps): Definition, Uses, Pros and Cons of dApps

Decentralized Applications (dApps) have emerged as a game-changer, redefining the way we interact with digital platforms.

Decentralized applications, or dApps, are software programs that run on a blockchain or peer-to-peer (P2P) network of computers ( group ) instead of on a single computer.

DApps are thus outside the purview and control of a single authority. DApps are often built on the Ethereum platform, but they can also run on other blockchains that support smart contracts,such as Cardano, Solana, Pi network or Binance Smart Chain.

DApps are a growing movement of applications that use blockchain technology to create more transparent, secure, and inclusive systems. They can be designed for a variety of purposes, such as gaming, finance, social media, supply chain management, identity verification, and more. In this article, we will explore what dApps are, how they work, what features they have, what examples of dApps exist, and what are the pros and cons of using dApps.

What are dApps?

The term dApp is short for decentralized application.

A dApp is an application that runs on a distributed network of computers, rather than on a centralized server or database. A dApp can have a user interface that is similar to a web or mobile app, but the back-end processes are different.

A dApp typically uses a blockchain as its underlying technology. A blockchain is a system of records that are stored in blocks and linked together by cryptography. Each block contains a timestamp, a hash of the previous block, and a set of transactions.

Transactions are the actions or events that occur on the blockchain, such as sending or receiving cryptocurrency, executing a smart contract, or creating a digital asset.

A smart contract is a piece of code that is stored on the blockchain and executed automatically when certain conditions are met. A smart contract can define the rules and logic of a dApp, such as how users can interact with it, what functions it can perform, and what outcomes it can produce. A smart contract can also facilitate the exchange of value or information between parties, without the need for intermediaries or trusted third parties.

A dApp can also use a peer-to-peer (P2P) networkto communicate and share data with other nodes or users. A P2P network is a network of computers that are connected directly to each other, without relying on a central server or authority. A P2P network can enable a dApp to operate in a decentralized and distributed manner, where each node can contribute to the network’s functionality, security, and resilience.

What are the features of dApps?

According to the Ethereum white paper, a dApp should have the following features:

  • It should be open-source, meaning that its source code is publicly available and anyone can inspect, modify, or contribute to it.
  • It should use a cryptographic token, such as a cryptocurrency or a utility token, to incentivize its users and secure its network. A token can also represent a unit of value, a digital asset, or a right within the dApp.
  • It should generate tokens according to a standard algorithm or protocol, rather than by a central authority or entity. This can ensure that the token supply is predictable, transparent, and fair.
  • It should use a blockchain or a P2P network to store and validate its data and transactions, rather than a centralized server or database. This can ensure that the data and transactions are immutable, verifiable, and censorship-resistant.

These features can distinguish a dApp from a traditional application, which is usually closed-source, centralized, and controlled by a single authority or entity.

How Decentralized Apps Work Step by Step?

Here are the main steps on how decentralized applications work:

  • A developer creates a dApp using a programming language that is compatible with a blockchain platform, such as Solidity for Ethereum. The developer writes the logic and rules of the dApp using smart contracts, which are self-executing pieces of code that run on the blockchain.
  • The developer deploys the dApp and its smart contracts to the blockchain network, where they are verified and stored by the nodes, or computers, that participate in the network. The nodes use a consensus mechanism, such as proof-of-work or proof-of-stake, to agree on the validity and order of the transactions and data on the blockchain.
  • The developer also creates a user interface for the dApp, which can be a web or mobile app that communicates with the blockchain network. The user interface allows the users to interact with the dApp and its smart contracts, such as by sending or receiving tokens, creating or accessing digital assets, or voting or governing the dApp.

  • The users access the dApp using a compatible wallet or browser, such as MetaMask or Brave, that can connect to the blockchain network and sign transactions with their private keys. The users can also use a cryptographic token, such as a cryptocurrency or a utility token, to pay for the services or functions of the dApp, or to receive rewards or incentives from the dApp.
  • The dApp and its smart contracts execute the transactions and data on the blockchain network, without the need for intermediaries or trusted third parties. The transactions and data are recorded and stored on the blockchain, where they are immutable, verifiable, and censorship-resistant. The dApp and its smart contracts can also update or modify themselves according to the predefined rules or conditions.

That is the simplified overview of how dApps work.

What are some examples of dApps?

There are many dApps that have been developed for various use cases and sectors. Here are some examples of popular or innovative dApps:

1. Decentralized finance (DeFi) apps

DeFi apps provide financial services without the need for traditional financial institutions to act as intermediaries. DeFi apps provide lending and borrowing, trading, and yield farming options determined by smart contracts. DeFi apps include;

  • Uniswap is a decentralized exchange (DEX) that allows users to swap tokens with ease. It uses an automated market maker (AMM) model, where users can provide liquidity to pools of tokens and earn fees from trading. Uniswap is one of the most widely used dApps on Ethereum, with over $3 billion of daily trading volume.
  • OpenSea is a marketplace for buying, selling, discovering, and trading digital collectibles, such as non-fungible tokens (NFTs). NFTs are unique and indivisible tokens that can represent art, music, gaming items, and more. OpenSea is the largest NFT marketplace, with over $10 billion of total sales volume.

2. Decentralized social media

Social platforms built on blockchains aim to give users control over their data and provide rewards – often in the form of cryptocurrency tokens – for contributing content.

Decentralized social media apps include microblogging platforms such as

  • Mastodon  Mastodon is a free social media service that functions much like Twitter. You can post “toots” (instead of tweets), follow other people and organizations, and favorite (like) and boost (retweet) posts from other people.
  • Steemit. Steemit is a blockchain-based blogging and social media website. Users can gain a cryptocurrency, called STEEM, for publishing and curating content (i.e. posts) and for commenting on posts.

3. Decentralized gaming

Games that run on blockchains can use non-fungible tokens (NFTs) to represent ownership of in-game items and reward users for their gameplay with cryptocurrencies. Developers can create content connected to a game, and players can vote on the way the game functions. Decentralized gaming apps include;

  • Gods Unchained is a strategic trading card game that is powered by blockchain. Players can collect, trade, and battle with cards that are represented by NFTs. Each card is owned by the player and can be sold or exchanged on the open market. Gods Unchained is one of the most popular blockchain games, with over 500,000 registered players.
  • Other decentralized gaming apps include Axie Infinity, Gods Unchained, and The Sandbox.

4. Ethereum Name Service

Ethereum Name Service Is a service that provides user-friendly names for Ethereum addresses and decentralized sites. Users can register a name that ends with .eth, such as alice.eth, and use it to send and receive cryptocurrency, access decentralized web pages, and more. ENS is a decentralized alternative to the traditional domain name system (DNS), which is controlled by centralized entities.

5. Decentralized music platforms

Decentralized music platforms, such as Audius, OPUS, and BitSong, offer an alternative to centralized streaming services. These platforms empower artists by allowing them to control their work and receive a fair share of the revenue they generate.

6. Decentralized storage applications

Decentralized storage applications, like Storj, Filecoin, and Swarm, leverage blockchain’s peer-to-peer functionality to establish a distributed network of storage space. This approach enhances security, fault tolerance, and resistance to data breaches compared to centralized storage.

7. Supply chain management

DApps designed for supply chain management enable businesses to monitor the movement of physical goods from manufacturers to consumers. The primary goal is to improve transparency and authenticity throughout the entire supply chain.
