Understanding Decentralized Applications (DApps)

Web apps like Facebook or Uber run on a computer system owned and operated by a company with authority over the app and its operations. The company always controls the backend, regardless of the app’s number of users. DApps operate differently. 

DApps are like any other digital application but employ blockchain technology to keep their users’ data out of the hands of the organizations behind them. As crypto is decentralized money, dApps are decentralized applications.

Key Takeaways

• Decentralized applications are digital applications free from a single authority‘s control and interference.
• The benefits of dApps include safeguarding user privacy, reducing censorship, and increasing development flexibility.
• Potential drawbacks include scalability, user interface challenges, and difficulties in making code modifications.

What is Dapp? 

A decentralized application (dApp) is a distributed, open-source software application that functions on a decentralized network of computers instead of relying on a single central server. DApps are similar to other applications on smartphones or laptops but are peer-to-peer (P2P) supported. DApps are considered part of Web3, the World Wide Web’s present evolution.

The decentralized nature means that once a developer has released a DApp’s codebase, others can build on top of it. A single authority does not control the app; it is operated autonomously and governed by smart contracts and consensus mechanisms.

Comparing Centralized and Decentralized Apps

Centralized apps are owned and run by a single entity, with data stored on centralized servers controlled by that entity. In contrast, decentralized apps run on P2P blockchain networks, with data distributed across multiple nodes, making them resistant to censorship and single points of failure.

Examples Of DApps

A few notable examples of DApps include:

1. Uniswap 

Uniswap is a decentralized exchange protocol powered by Ethereum (ETH). You can trade cryptocurrencies on this platform directly from their wallets without intermediaries. By leveraging automated smart contracts to create liquidity pools, Uniswap offers a seamless and secure trading experience. This dApp demonstrates the power of decentralized finance (DeFi) in revolutionizing traditional financial systems.

2. Steemit

Steemit operates as a blockchain-based social media and  platform. The website allows you to create and post content, which other users then react to and comment on. You can get rewarded for each post, and the interactions they initiate determine the reward size. 

3. Pancake Swap

Pancake Swap is among the numerous decentralized exchanges that utilize the source code of Uniswap. Unlike the latter, which is built on the Ethereum blockchain, Pancake Swap is built on the Binance Smart Chain ecosystem. Hence, it allows you to swap BEP-20 tokens instead of ERC-20.

4. Aave

Aave is an open-sourced liquidity protocol that provides complete transparency for its users. You can lend, borrow, stake, and earn interest on deposits. Thanks to the platform’s decentralized nature, lenders and borrowers can enjoy complete anonymity.

5. Upland 

Upland, a game built on the EOS platform, seamlessly blends the virtual world with reality, offering players an exceptional gaming experience. This gameplay is centered around the real estate trading simulation. All the properties are based on actual real-world locations, but the assets are backed by blockchain technology in the game. Upland has a play-to-earn (P2E) model that allows you to sell your in-game assets for real money.

Practical Applications For DApps

1. Financial services: DApps will help you  facilitate better P2P  financial transactions, such as exchanging currencies or transferring assets.
2. Supply Chain Management: DApps can monitor your product’s movement throughout a supply chain, ensuring transparency and accountability of your process.
3. Identity Verification: DApps can securely retain and authenticate your identity details, for instance, in your voter registries, passport requests etc.
4. Real Estate: DApps can enable direct buying and selling of real estate between you and another party and track property ownership and relevant documentation.
5. Healthcare: DApps can help you save and monitor your healthcare records and facilitate communication and collaboration between you and healthcare professionals.
6. Education: DApps can create decentralized learning platforms, whether as a student or teacher, allowing interaction and collaboration without intermediaries.
7. Social Media: Decentralized social media platforms will allow you to engage and distribute content without relying on a central server.

Pros Of DApps

1. Safeguarding User Privacy: DApps enable you to interact directly with each other without disclosing personal information, enhancing privacy and security. Smart contracts facilitate transactions without intermediaries, reducing the risk of data breaches and identity theft.
2. Resisting Censorship: The decentralized nature of dApps makes them resistant to censorship, ensuring freedom of speech and expression. Unlike centralized platforms, which can be subject to government regulations and content moderation, dApps operate autonomously, empowering users to share information freely.
3. Promoting Transparency: Blockchain-based dApps maintain transparent records of transactions, fostering trust and accountability among users. The blockchain records every transaction, creating an unchangeable and verifiable ledger accessible to all participants.
4. Enabling Global Accessibility: dApps are accessible to anyone with an internet connection, transcending geographical boundaries and financial barriers. This global accessibility democratizes access to decentralized digital services.

Cons Of DApps

1. Scalability Limitations: dApps face challenges in scaling to accommodate increased network congestion and transaction volumes. Blockchain networks like Ethereum have processing speed and throughput limitations, leading to delays and higher transaction fees during peak periods.
2. User Interface Complexities: Developing user-friendly interfaces for dApps can take time and effort, hindering mainstream adoption. Many dApps require users to interact with complex blockchain technology, including managing private keys and understanding smart contracts, which may deter less tech-savvy users.
3. Difficulties in Making Code Modifications: Due to blockchain technology’s immutable nature, dApps are difficult to modify once deployed. Making updates or fixes to the code requires consensus among network participants, leading to delays and complications in maintenance and debugging.
4. Maintenance and Updates: Maintaining and updating dApps can be cumbersome, requiring coordination among developers, miners, and users. Changes to the codebase must be carefully implemented to avoid disruptions to the network, highlighting the need for streamlined processes and governance mechanisms.

Scams Involving dApps

While dApps offer numerous benefits, they are not immune to scams like; 

1. Ponzi schemes, which involve using the investments of more recent investors to pay early investors and create the illusion of substantial profits, have been observed on dApps.
2. Fake initial coin offerings (ICOs) have been utilized to secure funds for developing a new cryptocurrency or dApp that the organizers have no plans to create.
3. Phishing attacks involving deceptive websites or emails aimed at obtaining sensitive information from individuals have been observed on dApps. 

Also, some dApps have been utilized to spread viruses, posing a threat to your devices and potentially resulting in the theft of sensitive information. You should be cautious and do your due diligence when interacting with dApps to avoid falling victim to such scams, as the decentralized nature of these applications can make it difficult to track or hold perpetrators accountable.

Bottom Line

In conclusion, dApps is revolutionizing the way we build applications. It offers a decentralized alternative to conventional centralized applications where companies are in charge of everything that goes on with the applications. 

While decentralized applications promise transparency and autonomy, they also face challenges that must be addressed to unlock their full potential. With continued innovation and collaboration, dApps have the potential to reshape industries and give people a say in the development and continous improvement of applications they use.
