All You Need to Know about Decentralized Applications (DApps)

Check out this ultimate guide on decentralized applications (DApps). It highlights key features and benefits of DApps and tells you how to identify high-risk apps.

Decentralized apps (DApps) make it possible for people to interact with personal finance without third-party involvement.

If you’re new to the cryptocurrency and the blockchain world and are looking to gain an in-depth understanding of DApps, this guide is for you!

What is a DApp?

A DApp is a digital application or program that runs on a decentralized computing system (a blockchain or P2P network). They’re decentralized because no single entity controls them, and dApps are usually controlled by a network of P2P (peer-to-peer) computers.

DApps combine smart contract backend and frontend user interface. The frontend code and user interfaces are written in different languages that can make calls to the backends.

No single authority controls them; users and providers can interact with each other directly. Each DApp has a unique code that may only work on a particular platform. This code replaces the middle man, providing cost and time savings.

Key Features of DApps

Below are the main characteristics of DApps.

·         They exist and run on a blockchain network.

·         They have an open-source code that operates on its own without any individual or group interfering or controlling the tokens.

·         They provide value to users with DApp tokens.

·         They offer tokens as a reward to users when they contribute positively to the ecosystem.

How Are DApps Different from Apps?

Here are the main differences between a DApp and a regular app.

·         In regular apps, the user interface interacts with a traditional program, whereas in DApp, it communicates with smart contracts.

·         The back-end of regular apps is hosted on a single computer or centralized servers. On the contrary, dApps are hosted on multiple systems worldwide via an open-source, peer-to-peer network. DApp data is recorded on a public blockchain.

·         Regular apps stop working if the central server fails. For DApps, the failure of a particular network node doesn’t affect the network as a whole.

·         DApps have a higher computing power than regular apps. This is why a sudden user influx doesn’t cause any disruptions or performance slowdowns.

·         DApps are much more secure than regular apps. The centralized processing units of the latter are at risk of cyber-attacks.

·         Unlike regular apps, DApps continue to work normally even when particular network nodes go offline.  

So, basically, a DApp can do everything a regular app does. It’s just that its back-end acts as “distributed” and “decentralized”.  

DApp Examples

Uniswap, BitTorrent, OMG Network, and are some examples of decentralized apps. They run on computers that together form a P2P network. On these apps, several users either consume or feed content or do both simultaneously.

A few examples of DApps in the cryptocurrency world are shared below.

Ethereum was designed to create DApps. Its unique programming language was meant to create smart contracts to power these apps. Although it has some scalability issues and increasing competition, it remains a top choice for DApp development.

Check out some examples of DApps on this blockchain platform below.

EOS isn’t really a decentralized platform since it’s controlled by It was initially developed on Ethereum, but it later started working independently. Unlike Ethereum, this blockchain offers faster transactions and doesn’t have any transaction fees.   

Everipedia moved to the EOS blockchain platform in 2018, becoming the world’s first decentralized encyclopedia. This status offers protection against censorship.

Are DApps Safe?

With a DApp, your data is stored in encrypted form in network nodes. The operation is completely transparent. It is recorded on the public ledger to ensure users’ peace of mind. No data or transaction can be erased once it has been generated.

Users find it easier to trust DApps because they allow them to enjoy full ownership and control of their data and assets.

However, there are some high-risk DApps with the bearing of a Ponzi scheme or a pyramid. They can run for extensive periods without cracks. Hence, you must do your research before investing in any DApp project. A good rule of thumb is to avoid investing more than what you can afford to lose.

Below are a few signs that will help you identify a high-risk DApp.

·         It offers a guarantee of big returns with minimal risk.

·         It promises a consistent stream of returns regardless of the market conditions.

·         It makes false claims of working with renowned wallets and exchanges.

·         It claims to be decentralized and transparent when it’s not.

·         It promises to offer token rewards whenever a user joins under you.  

·         You face difficulties when removing tokens on the platform.

Why DApps?

DApps allow data to be decentralized, making it tamper-proof. The top benefits offered by them include:

·         Users can make direct cryptocurrency transactions without having to integrate with a payment provider.

·         Users can bind their sessions and data easily and enjoy varying degrees of anonymity without completing lengthy registration processes.

·         Open-source DApp code is accessible to all useras and can easily be understood by beginners.

·         All enclosed data remains inherently secure.

·         A public record stays on the blockchain, making it easy for users to audit it.   

What is the Best DApp?

Here’s the thing… There are so many dApps out there (and new ones coming out!). But we’ve rounded up the top two DApps that could possibly dominate the future investing world.

1.     Uniswap

The screen display of Uniswap website. The Launch App option can be seen on the top rightmost corner of the site.

Launched in 2018, the US-based Uniswap is used for exchanging Ethereum and other digital currency tokens. It also has a pool feature that allows users to deposit tokens in a smart contract for enhanced liquidity and gain pool tokens in return.  

Some of the reasons users love Uniswap include self-custody, low trading fees, and a variety of tokens for trading. Another reason that makes Uniswap a preferred option is that it doesn’t require a Know Your Customer process. This means you can set up your account and start trading right away.

This DApp also promises to keep your personal info protected in case the exchange gets hacked.  

2.     IDEX

The screen display of IDEX website. It includes main options such as Learn More and Launch IDEX Classic.

IDEX is one of the most advanced cryptocurrency exchanges. It was launched in 2016. It is currently available for Ethereum and Bitcoin blockchains only. Interestingly, it was the first Ethereum-based dApp to allow real-time trading.  

This DApp allows users to place multiple orders at any given time instead of waiting for the mining of transactions. On top of this, they can cancel orders without having to pay a gas cost.

Furthermore, IDEX has its own token that enables investors to earn a share of the amount generated by the exchange. Security is also a huge selling point for this DApp.

3.     MakerDAO

The screen display of MakerDAO website.

MakerDAO is an independent platform for lending cryptocurrencies. Its digital currency is called Dai. On this platform, users can borrow and lend using a DApp without any third-party involvement.

Like Uniswap, it doesn’t require users to complete the Know Your Customer process.

One of the biggest reasons users trust this DApp is Dai’s stability as a currency. Its value is connected to the US dollar. This is a huge benefit, considering how wildly Bitcoin’s value tends to fluctuate.

Apart from this, Dai isn’t associated with any particular country. Hence, no banks or governments control lending, borrowing, or overspending on MakerDAO.

This DEX aggregator has an in-house token called ORN. As an investor or trader, you can use these tokens for liquidity mining or staking.

How Does the DApps Future Look Like?

The number of DApps is growing rapidly. The market size is likely to reach $368.25 billion by 2027.

Considering the fact that DApps aren’t owned by anyone, can’t be shut down, and are more secure against cyber-attacks, they may significantly impact the way we work, commute, communicate, and more.

DApps are reducing costs and eliminating third parties from our personal and business financial transactions. They have taken transaction security and automation to the next level.     

We can expect DApps to influence the following industries:

·         Banking

·         Real estate

·         Energy

·         Gambling

·         Internet of Things

·         Social media

·         Identity verification

·         Elections and voting

Furthermore, we may see improvements in the interface design and structure of DApps. This will have a positive impact on the overall user experience. More investors are jumping in to capitalize on the efficiency of these apps.

🟢 For owners who have made impactful changes and would like an update to their farm review:

1️⃣ Use #update at @RugDocChat with your description and proof of changes and it will be forwarded to our scanners.

2️⃣ This does not guarantee a change in your review.

3️⃣ Owners who have difficulty solving the issues can consider our Consultation Package – please contact @BaymaxCrypto on Telegram to discuss.

Our mission here at RugDoc is to screen for hard rug code that results in 100% theft of ALL underlying funds for ALL participants.

This is the ONE part of the due diligence process that most people cannot simply do on their own as it costs thousands of dollars to hire a senior solidity developer to look over a farm for safety.

A project coin with terrible code can go up in price, and a project with good code and a good team can also go down in price.

Do NOT use our ratings to refer to your likelihood in making money if you invest in the project. They are ONLY in reference to code safety.

Everything else beyond code safety is YOUR responsibility to go do research on. We just make sure the casino you’re betting in won’t rob you before you even get to place a bet.

Our reviews for projects are organized into a few colors.

🟢 Least Risk
These projects are the least likely to hard or soft rug. Usually reserved for cornerstone projects of an ecosystem where it makes no financial sense for them to rug in any manner as they make more money just being legit.

🔵 Low Risk
These projects are usually established projects in an ecosystem that have a track record of success or have KYC’d to us or other authoritative sources in the real world. As a result, it is extremely unlikely for them to soft rug or hard rug their projects. The projects can still fail and the token price can go down, but usually more as a result of natural market forces.

⚪️ Some Risk
This is the default rating for projects with unknown teams but have code that is unlikely to have hard rug risk. Since the team is unknown and doesn’t have a track record of success, it’s entirely possible that they may try to soft rug by dumping tokens, abandoning the project, etc. Even a last minute contract swap to a malicious contract is possible. The only thing that is unlikely is a complete hard rug as long as you are 100% sure you deposit into the contract we review.

🟠 Medium Risk
Similar to Some Risk, but the underlying code itself is custom enough or complex enough that it warrants an elevated risk rating that needs deeper research. Make sure you read every point presented to make sure you’re comfortable with that before entering. Still unlikely to hard rug, but more chances of custom code behaving incorrectly and causing other issues.

🔴 High Risk
Project contains code or practices that are HIGHLY LIKELY to lead to catastrophic losses as they are right now. Make sure you read the description carefully as we will always warn what these issues are. If you see the words Hard Rug anywhere in the review, STAY FAR AWAY!

⚫️ Not Eligible
We reserve the right to not review exceedingly complex projects that would require tens of thousands of dollars of senior security analyst man hours. Typically these are projects that deal with leverage, lending, options, derivatives, and anything that is overly complex and which requires tons of peer reviews and audits from top audit companies.
