Dapps have created a significant amount of excitement. But why is that? To understand the answer, it’s important to recognize the value of applications. Nowadays, digital applications play a crucial role in people’s daily lives. Whether it’s using Zoom for virtual conferences, collaborating with team members through Google Workspace, connecting with friends on Facebook, or playing games, applications are an integral part of our lives. Dapps are significant because they represent the next level of applications. They have already revolutionized the way applications function, and they have the potential to greatly impact how applications are used. In this article, we will provide a comprehensive overview of Dapps, including their definition, how they operate, their advantages and disadvantages, and much more.

What Are Decentralized Applications (Dapps)?
Dapps are decentralized versions of applications. In 2014, a report called “The General Theory of Decentralized Applications, Dapps” was published, introducing a new model for constructing applications. According to this report, Dapps must possess the following features: open-source code that can be viewed and modified by anyone, peer-to-peer transactions without involving third parties, the ability for users to alter the Dapp’s rules, and storage of transaction records in a blockchain database. Moreover, Dapps should only support cryptocurrencies and provide rewards to contributors like miners and stakers. They should also incorporate a consensus method for generating tokens, such as proof of work (PoW) and proof of stake (PoS). Additionally, the paper categorizes Dapps into three layers.
Layer 1 consists of Dapps that exist independently on their own blockchain, with their own consensus mechanism and built-in rules. Examples include Bitcoin, Ethereum, and $SHIB. The paper refers to these blockchains as layer 1 Dapps.
Layer 2 Dapps are built on top of layer 1 Dapps and leverage the power of the underlying layer 1 blockchain. These Dapps are often considered protocols and utilize tokens for interactions. Layer 2 Dapps serve as layer 2 blockchain solutions, processing transactions off the layer 1 Dapp and then transferring the data back to the layer 1 Dapp, thereby reducing the load on the layer 1 Dapps.
Layer 3 Dapps exist on top of layer 2 Dapps and encompass various types of applications such as gaming, finance, and medicine. According to the paper, Dapps are defined as any product utilizing blockchain technology, though the term “Dapp” is commonly used to refer to layer 3 Dapps.
Benefits And Drawbacks
Dapps offer numerous advantages and disadvantages, which we will discuss in detail.
Benefits:
– Reduced downtime: Traditional apps rely on a single server, so if it encounters problems, the app may cease to function until the issue is resolved. Dapps, on the other hand, do not have a single point of failure. With thousands of nodes responsible for running the Dapp, the failure of a few nodes does not significantly impact its performance.
– Immutability: Dapp transaction records are stored in blocks, and modifying or deleting these records requires reversing the block’s hash. If the hash is modified, the block becomes disconnected from the blockchain. This makes it extremely difficult for hackers to manipulate transactions.
– No transaction manipulation: Transactions within Dapps cannot be manipulated by any entity. To control a transaction, a hacker would need to control the majority of mining nodes in the entire blockchain network. Given the vast number of nodes in large blockchain networks, hacking this many nodes is virtually impossible.
– Open source: Dapps are open-source applications, meaning anyone can view and review the code. This transparency enhances trust in Dapps, as users can easily identify any errors or vulnerabilities within the code.
– Simplified procedures: Unlike traditional banks, Dapps eliminate complex procedures. Users do not need to fill out lengthy forms or endure waiting periods for approval. Transactions through Dapps are significantly faster than those through banks, which can take several business days.
– Enhanced privacy: Unlike corporations that require users to provide personal information for accessing their products, Dapp users do not need to disclose any personal information. This eliminates concerns about personal information being stolen and reduces the risk of financial loss due to data breaches.
Drawbacks:
– Slower updates: Unlike centralized organizations that can easily make changes, Dapps lack a central authority for decision-making. Even minor changes require a consensus among the majority of Dapp users, making the process time-consuming and challenging.
– Increased requirements: Launching a Dapp entails fulfilling various requirements, including establishing a user base, nodes, and a consensus mechanism. This creates additional complexities for Dapp creators.
– Accessibility challenges: Accessing a Dapp is more complicated than downloading a traditional app. To use a Dapp, users need to download a Dapp-compatible browser, purchase a compatible wallet, and acquire the necessary cryptocurrency. While tech-savvy individuals may find this process manageable, non-tech-savvy users may struggle to understand and perform these actions.
– User experience limitations: Dapps often offer a less user-friendly experience. As mentioned earlier, accessing and using them can be challenging. Additionally, instead of using conventional usernames and passwords, Dapps employ public and private keys that can be difficult to remember.
Dapps Usage
Now that we have covered the definition, benefits, and drawbacks of Dapps, let’s explore their various uses.
Browsers: Dapp browsers offer enhanced user privacy by blocking websites from accessing user information without consent. They also allow users to earn cryptocurrency while browsing, making the browsing experience more rewarding.
Gaming: Dapps bring the Play-&-Own model to the gaming industry, enabling players to own in-game assets. Unlike traditional games where customization is possible but asset sales are not permitted, the Play-&-Own model empowers players to sell their assets, providing true ownership.
Voting and governance: The current voting system is often inconvenient and time-consuming. Dapps offer a more efficient and fair voting solution by leveraging blockchain technology, eliminating the need for physical polling stations and preventing tampering.
In conclusion, Dapps represent an advanced form of applications that have the potential to transform the way we interact with software. While they offer numerous benefits such as reduced downtime, immutability, and enhanced privacy, they also come with drawbacks like slower updates and accessibility challenges. Nevertheless, Dapps have diverse applications ranging from browsers to gaming and voting. Exciting times lie ahead as Dapps continue to evolve and shape the future of software.
