Can you imagine using an app that is immune to censorship and doesn’t require a central authority? That’s precisely the idea behind decentralized applications or dApps.

They provide users with complete control and easy access to smooth operations. 

Unlike regular apps controlled by a single entity, decentralized applications are based on blockchain technology.

They’re like a global computer network you co-own with millions of users, thus making it very hard to shut down.

This guide explains dApps, how they work, their perks, and their applications in various sectors. 

What are Decentralized Applications?

Decentralized Applications (dApps) are software applications that run on a blockchain network. This shared network makes them more transparent and resistant to censorship. A dApp makes transactions more transparent and secure, as everyone can see the information publicly, and no single entity can tamper with it. 

They offer so many possibilities. You can use them to engage in decentralized finance (DeFi) services, where you can transact money directly with others without needing banks. Additionally, gaming, governance, or digital art generation is possible with dApps. 

Though dApps are still new participants within the DeFi field, their potential for users to have more decision-making powers is evident. Before delving into how they work, let’s walk through the memory lane of how decentralized applications started.

How Decentralized Apps Came About

The core idea behind cryptocurrency was to offer an alternative to fiat. This is how Bitcoin came into existence. While utilizing blockchain technology, Bitcoin transformed how users transact without needing intermediaries. However, the potential of blockchain stretches far beyond finance.

This is when Vitalik Buterin enters the scene to provide an alternative to Bitcoin: altcoins. In 2013, he proposed a new project, Ethereum — a platform that offers a new approach to interacting with the digital world. 

Here, control will not be in the hands of corporations or central organizations but with the users only. The key to this vision? You guessed right – smart contracts! These smart contracts are written directly on the blockchain. Thus, they enable secure and transparent transactions. 

However, it’s significant to note that the likes of Buterin had companions in his vision. By 2014, the key characteristics of a dApp were described in “The General Theory of Decentralized Applications.” According to the paper, dApps should be open-source and controlled by the user. Also, all information must be recorded in the public blockchain.

In addition, dApps should utilize tokens to gain access and incentivize users through rewards. The paper then proposed a three-tiered system for understanding dApps:

Layer One

It includes Bitcoin-type blockchains or some other independent blockchains with their consensus mechanisms and built-in rules. 

Layer Two

These are applications developed on the framework of existing blockchains and may involve transaction tokens. These can act as scaling solutions by processing transactions faster and more efficiently off the main chain.

Layer Three

These are applications built on top of layer two, providing APIs and scripts that allow layers one and two to function seamlessly. It’s like a user-friendly interface for interacting with the underlying dApps.

How Do Decentralized Applications Work?

Having seen the core foundations behind decentralized applications, let’s consider how they work. Imagine a food-delivery app that connects you directly with restaurants, all powered by secure and automated agreements. That’s the potential of dApps. But how do they work their magic of decentralization? Let’s consider these four concepts: 

Smart Contracts

These are self-executing programs coded onto the blockchain. These contracts handle tasks based on predefined rules. In our food-delivery app example, a smart contract could connect you to a restaurant that has your order available and confirm your payment. No human intervention is needed!

Blockchain Technology

This is a public ledger of information replicated across a network of computers. In dApps, it keeps a transparent record of transactions, interactions, and even the code itself. This ensures everyone can see what’s happening, and no single entity controls the data.

Cryptocurrency

These are digital tokens that act as fuel for dApps. They can be used for payments within the app, like paying for your food. Some dApps have special tokens that give voting rights to users on how the app should grow.

Oracles

We can think of these as data bridges. dApps often need real-world information, like traffic updates for our food-delivery example. Oracles securely fetch this external data and feed it to the dApp’s smart contracts.

Now, let’s see how it all works together. When you order food on a dApp, a smart contract kicks in. It checks your payment through your crypto wallet, verifies what restaurant has your order available, and automatically connects both of you. The entire transaction is then recorded on the blockchain for transparency.

Why Use a DApp? Consider The Advantages

DApps offer numerous perks, from instantly sending money to a friend to accessing your medical records without a giant corporation controlling your data. Indeed, there are many possibilities regarding dApps. Here are some ways they transform how we interact in the financial system.

Eliminate Intermediaries and Save Money

Remember the frustration of paying a fee to transfer money between accounts? With dApps, smart contracts automate transactions. Thus, they eliminate third-party services and their associated fees. It’s like sending money directly to a friend, peer-to-peer, with minimal charges. Plus, transactions are almost instant, saving you valuable time.

Safe and Secure

Centralized servers are vulnerable to attacks, which leads to security breaches. Since dApps run on blockchain, they are nearly impossible to hack. Thus, you can easily access your data and services anytime.

Enhances Trust

Frequent data breaches and privacy scandals have eroded trust in large corporations. Decentralized applications offer a solution. Their transparent nature lets you see exactly what goes on behind the scenes. Since operations are automated via smart contracts, human error is removed, which promotes trust in the system. 

Cons of Decentralized Applications

Decentralized applications sound amazing — a world free of corporate control, with fast, secure transactions. But before we pack our bags and move in, there are a few things to consider. Let’s highlight a few hurdles to this rising technology:

Slow Updates

Imagine needing everyone in your neighborhood to agree before you repaint your house. That’s how dApp updates work. When there’s a need for change, even minor fixes, it requires a large group of networks to agree, which may take a while. As a result, updates become slowed, and users may have to wait to access new upgrades and features. 

Limited Users 

Decentralized apps are still new and less popular than established apps. This means they may lack the needed user base and tools to run smoothly. Imagine a top-rated restaurant with no available customers – that’s the challenge some dApps face.

Scalability Issues

Many blockchains can become less efficient due to several users on them at once. Despite the prevalence of layer-two networks, transactions are often slow, which can create a frustrating wait.
