What are dApps (decentralized applications)?

Key Takeaways

Applications are the backbone of many of our daily activities, chances are you’ve already interacted with at least one today. From online banking, to social media, gaming, or even booking an Uber, all the services you can access from your phone are run on applications. But a new generation of apps are about to change the way we interact with one another.

Decentralized applications run on blockchain networks and according to DappRadar, there are already thousands of them. As their number grows, understanding what makes them work becomes increasingly important.

In this article, we’ll explore decentralized applications, what makes them unique, the different types, and their advantages and disadvantages.

What Are Decentralized Applications (dApps)?

Decentralized applications are software applications that run on a decentralized blockchain network.

Unlike conventional applications, which run on a single server and have a single point of failure, decentralized applications run on a distributed network of nodes. This means no single entity (such as a government or a hacker) can control, alter, or shut them down. So dApps represent a new frontier in software development, offering a system that is resistant to censorship, fraud, and third-party interference.

And dApps offer another interesting proposition too: with blockchain as their foundation rather than a company, decentralized applications enable peer to peer transactions. For example, if you provide tokens to a liquidity pool you’ll receive rewards in return, with no middle man controlling the transaction. Instead, the transaction is facilitated by an underlying protocol.

Smart Contracts Explained

At the core of most dApps lies the concept of smart contracts, self-executing agreements with the terms written into code. Smart contracts automatically enforce agreements once their predefined conditions are met. 

In contrast to traditional contracts, which require intermediaries to oversee execution and ensure compliance, smart contracts operate autonomously on the blockchain, ensuring that all parties involved adhere to the agreed terms without the need for manual intervention.

For example, in a decentralized finance (DeFi) platform, a smart contract can automatically execute a loan agreement when certain conditions are met, such as when collateral is deposited. This automation reduces the risk of human error and eliminates the need for trust between parties.

Difference Between a Centralized and Decentralized App

It can be hard to conceptualize the differences between regular apps and dApps, but their distinctions can be found along three main themes:  

• Managed by a single authority vs distributed on a decentralized network
• Can be  easily, restricted or censored vs resistant to censorship
• Have a single point of failure vs no single point of failure

Centralized Applications

To understand the significance of dApps, it’s essential to discern them with traditional, centralized applications. Centralized apps are managed by a single organization that controls the servers, data, and operations. This central authority can modify, restrict, or even shut down the app, which can lead to issues such as censorship, data breaches, and single points of failure.

Decentralized Applications

On the other hand, dApps operate on decentralized networks like Ethereum, where data and operations are spread across numerous nodes. This decentralization means that no single entity has control over the application, making it more resistant to censorship, more secure against hacks, and generally more transparent. 

Furthermore, dApps often operate on open-source protocols, allowing anyone to inspect the code and understand how the application works. This fosters a community-driven approach to development and governance, where in many cases users have a direct say in the direction of the app.

Why Do dApps Matter?

The significance of dApps extends beyond their technical framework. They represent a new way in how digital services are delivered and consumed, offering several key advantages over traditional apps.

Cost and Efficiency

One of the primary benefits of dApps is their potential to reduce costs and increase efficiency. By eliminating intermediaries, such as banks, brokers, or other third parties, dApps streamline processes and lower transaction fees. 

For instance, in the financial sector, decentralized exchanges (DEXs) allow users to trade assets directly with one another. This peer-to-peer trading reduces costs and increases the efficiency of transactions, making the services more accessible.

Security/Censorship

dApps are inherently more secure than their centralized counterparts due to their decentralized nature. Because dApps run on a network of nodes rather than a single server, they are less vulnerable to hacks, data breaches, or government censorship. 

Even if one part of the network is compromised, the rest of the system continues to operate, ensuring the integrity and availability of the application. This is particularly valuable in regions with restrictive governments or in industries where data security is essential.

Accessibility

dApps offer greater accessibility than traditional apps, as they can be used by anyone with an internet connection, regardless of geographical location. 

Global accessibility makes dApps particularly valuable in regions where access to financial services, healthcare, or other essential services is limited. By providing a decentralized alternative, dApps empower individuals to participate in the global digital economy, regardless of their location.

Transparency

Transparency is a core principle of dApps, as all transactions and operations are recorded on a public blockchain. It ensures that users can verify the integrity of the system and understand how their data is being used. 

In contrast to traditional apps, where data is often stored in proprietary databases, dApps operate on open, public ledgers that anyone can inspect. This fosters trust among users and reduces the potential for fraud or manipulation.

Types of dApps

dApps come in many forms, each serving different functions within the blockchain ecosystem. Below are some of the most common types:

Decentralized Exchanges

Decentralized exchanges (DEXs) allow users to trade cryptocurrencies directly with one another without the need for a middleman. In other words, it means you’ll retain full custody of your assets even as you trade.

Why does this matter? 

A famous example is the FTX case. FTX was a centralized exchange, which mismanaged user funds resulting in massive losses in the billions. Since user assets were on an exchange wallet, investors didn’t have the option to withdraw their holdings before the company became insolvent.  

Decentralized exchanges allow users to trade assets directly from their wallets, reducing the risk of losing funds to exchange hacks or insolvency. Additionally, DEXs operate without a central point of control, making them more resistant to censorship and government intervention. This also ensures that trading activity is transparent and accessible to anyone.

Decentralized exchanges such as Uniswap and SushiSwap, enable peer-to-peer trading by matching buyers and sellers through smart contracts. DEXs offer several advantages over centralized exchanges, including lower fees, increased security, and greater user control over funds.

Gaming 

Blockchain-based games have emerged as one of the most popular use cases for dApps, offering players new ways to earn and own digital assets. Axie Infinity, for example, was among the first play-to-earn games. It allows players to collect, breed, and battle digital creatures called Axies. 

These Axies are represented as non-fungible tokens (NFTs) on the Ethereum blockchain, giving players ownership of their in-game assets. In addition to owning Axies, players can earn cryptocurrency rewards through gameplay, creating new income opportunities in the digital world.

Metaverse

The metaverse represents a virtual world where users can interact, create, and transact in a decentralized environment. The Sandbox is one such platform that allows users to buy, sell, and trade virtual land and assets, all of which are represented as NFTs.

In The Sandbox, users can build and monetize their own experiences, ranging from virtual real estate to games and social spaces. By leveraging blockchain technology, The Sandbox ensures that all assets within the metaverse are owned and controlled by the users. It empowers creators to earn income from their contributions and fosters a vibrant ecosystem of digital experiences.

NFT Marketplaces

NFTs have gained widespread attention for enabling the ownership of digital and physical assets in a secure and immutable way. Artists, musicians, and creators can use NFT marketplaces to monetize their work directly, without relying on intermediaries. 

NFT marketplaces like OpenSea and Rarible enable users to buy, sell, and trade unique digital assets, such as art, music, and collectibles in the form of NFTs. These platforms operate as decentralized applications, ensuring that ownership and transaction history are transparent and verifiable on the blockchain. 

On decentralized NFT marketplaces such as OpenSea and Rarible, even when a user is listing an NFT for sale, the exchange is wallet to wallet. This means there’s no need to transfer the asset to the marketplace. However, not all NFT markets are decentralized.

This direct connection between creators and consumers has opened up new opportunities for innovation and revenue generation.

Fast Fact

Scams Involving dApps

While dApps offer many benefits, they are not without risks. Scams and fraud can still occur within the decentralized space, often exploiting the trust and transparency that dApps aim to provide.

Smart Contract Exploits

Hackers may exploit vulnerabilities in smart contracts to steal funds or manipulate the system, leading to significant financial losses for users.

Phishing Attacks

In phishing scams, attackers impersonate legitimate dApps or wallets to steal private keys or other sensitive information. They remain a prevalent threat in the decentralized space because phishing relies on the human element.

Rug Pulls

In a rug pull, developers of a dApp suddenly withdraw all funds from the liquidity pool, leaving investors bankrupt. This type of scam has become increasingly common in the DeFi space.

Fake dApps

Some scammers create fake dApps that mimic legitimate ones to trick users into depositing funds or sharing private information, only to disappear once they have acquired enough funds. Fake crypto exchanges are one common example of this scam, and it’s always worth carefully verifying the legitimacy of any new crypto exchange you use.

Advantages and Disadvantages of dApps

Decentralized applications have their share of pros and cons. Here are some of the benefits and drawbacks that users should consider.

Advantages

The pros of dApps are a direct result of the technology that empowers them. Thanks to blockchain technology, decentralized applications are:

• Decentralized: dApps are not controlled by a single entity, reducing the risk of censorship and centralized failure.
• Transparent: All transactions and operations are recorded on the blockchain. Users can always verify the integrity of the system.
• Secure: The decentralized nature of dApps makes them more resistant to hacks and data breaches.
• Globally Accessible: The only requirement to use a decentralized application is an internet connection.

Disadvantages

Much like the pros, the disadvantages of dApps stem from blockchain tech.

• Complexity: dApps can be more challenging to use than traditional apps, requiring a certain level of technical knowledge.
• Scalability: Many dApps face scalability issues, as decentralized networks can become slow and congested under heavy usage.
• Regulatory Uncertainty: The legal status of dApps remains unclear in many jurisdictions, which can create risks for developers and users.
• Smart Contract Vulnerabilities: Bugs or vulnerabilities in smart contracts can lead to financial losses or system failures.

Are dApps Regulated?

The regulation of dApps remains a grey area in many regions. Regulators are naturally having a hard time with dApps because, in the traditional sense, there’s no company behind the application. Plus, many dApp projects operate in jurisdictions with more lenient regulatory frameworks.

Nonetheless, blockchain space and dApps generally are coming under increased scrutiny over time, thanks to their reputation as the “Wild West”. The U.S. Securities and Exchange Commission (SEC) has shown interest in regulating certain types of dApps, particularly those involved in financial transactions or offering investment opportunities.

With the legal status of dApps currently unclear, the introduction of new laws and regulationsn will be gradual. These could potentially address the unique challenges posed by decentralized applications.

Closing Thoughts

Decentralized applications are changing the way we think about technology. In comparison to their traditional counterparts, dApps offer enhanced security, transparency, and user control. dApps come with their own set of risks and challenges that both user and investors should be well aware of.

While the benefits of dApps may outweigh the drawbacks, it’s their legal status that might be the deciding factor for their future.
