What is a Decentralized applications (dApps):
Decentralized applications, often referred to as dApps, are digital applications or programs that run on a blockchain or peer-to-peer (P2P) network of computers instead of a single computer. They are outside the control of any single authority.
Here are some key characteristics of dApps:
Decentralization: dApps run on a blockchain network in a public, open-source, decentralized environment and are free from control and interference by any single authority.
Uses: dApps have been developed for a variety of purposes including gaming, finance, and social media1. They can facilitate peer-to-peer financial transactions, track the movement of goods through a supply chain, and securely store and verify identity information.
Benefits: The benefits of dApps include the safeguarding of user privacy, the lack of censorship, and the flexibility of development.
Drawbacks: Potential drawbacks include an inability to scale, challenges in developing a user interface, and difficulties in making code modifications.
For example, a developer can create a Twitter-like dApp and put it on a blockchain where any user can publish messages. Once posted, no one — not even the app creators — can delete the messages. This is in sharp contrast to standard apps which typically run on centralized servers.
What is the difference between dApps and traditional apps?
Decentralized applications (dApps) and traditional applications (Apps) differ in several ways:
Centralization vs Decentralization: Traditional apps are governed by a centralized authority and run on centralized servers. In contrast, dApps run on a decentralized, peer-to-peer blockchain network.
Trust: dApps are trustable among users as they have control and ownership of their data and assets. However, users of traditional apps must trust the central authority to process their data securely.
Cost of Development: The cost of developing a traditional app includes factors like cloud server fees and maintenance fees. For dApps, the cost includes development, deployment, and upgrades.
Speed: dApps are generally slower than traditional apps. For instance, some dApps can process only around 15 transactions per second.
Security: Blockchain-based dApps are more secure compared to regular mobile apps. They are tamper-proof, and the records stored are unalterable.
Usage Cost: Most regular apps are free for users, but this may not always be the case for dApps.
In summary, while dApps offer benefits like transparency, immutability, and user control over data, they also face challenges such as scalability and user-friendliness. On the other hand, traditional apps prioritize user-friendliness and efficiency but are prone to centralized vulnerabilities.
Types of Decentralized Applications (dApps)
Decentralized applications (dApps) can be categorized into several types based on their functionalities:
Financial dApps: These are applications where money is involved. They facilitate peer-to-peer financial transactions, such as the exchange of currencies or the transfer of assets.
Semi-financial dApps: These dApps involve money but also require another piece, such as data from outside the blockchain.
Gaming dApps: These are games that run on a blockchain network.
Social Media dApps: These are platforms for social interaction that run on a blockchain network.
Supply Chain dApps: These dApps track the movement of goods through a supply chain, ensuring transparency and accountability.
Identity Verification dApps: These dApps securely store and verify identity information, such as for voter rolls or passport applications.
Other dApps: This category includes all other types of decentralized apps that developers are looking to create, including online voting and storage apps.
Each type of dApp has its own unique features and uses, and they all contribute to the diverse ecosystem of decentralized applications.
How can I earn money with dApps?
There are several ways to earn money with decentralized applications (dApps):
Trading and DeFi Apps: Decentralized exchanges and DeFi apps often have high volume. You can trade cryptocurrencies with leverage, borrow and lend cryptocurrencies all in a decentralized manner.
Liquidity Pools: You can add liquidity to liquidity pools on decentralized exchanges like Uniswap, SushiSwap, and Balancer, and earn trading fees.
Blockchain Games: Some blockchain games allow you to earn money. For example, some kitties on the Ethereum-based blockchain game “CryptoKitties” were sold for over a hundred thousand dollars.
Airdrops or Special Campaigns: By following the dApp space closely and participating in airdrops or special campaigns, you can earn some cryptocurrencies or crypto collectibles.
Crowdsale and Token Launch: You can bootstrap a project through crowdsale and back it with an asset token.
Transaction Fees: Some dApps allow you to earn money through transaction fees.
Premium Services: Offering premium services is another way to earn money with dApps.
Subscriptions: You can offer subscription-based services.
Advertisements: Displaying advertisements is another way to earn money with dApps.
Donations: Accepting donations is also a way to earn money with dApps.
Creating Digital Goods: You can create and sell digital goods.
Referral Marketing: You can earn money through referral marketing.
Examples of dApps
Here are some examples of decentralized applications (dApps):
Uniswap: Uniswap is a decentralized exchange protocol built on Ethereum. It allows for the trading of ERC20 tokens directly from a web browser, without the need for an intermediary.
CryptoKitties: CryptoKitties is a blockchain-based virtual game that allows players to adopt, raise, and trade virtual cats. The game is one of the earliest attempts to use blockchain technology for leisure and entertainment.
Compound: Compound is a decentralized, blockchain-based protocol that allows you to lend and borrow cryptocurrencies. Lenders earn interest on the cryptocurrency they supply to the protocol and borrowers pay interest to borrow it.
Decentraland: Decentraland is a virtual reality platform powered by the Ethereum blockchain. Users can create, experience, and monetize content and applications.
MakerDAO: MakerDAO is a decentralized credit platform on Ethereum that supports Dai, a stablecoin whose value is pegged to USD. Users can open a collateralized debt position (CDP), lock in ether as collateral, and generate Dai as debt against that collateral.
Augur: Augur is a decentralized prediction market platform. It allows users to create their own markets for specific questions they may have and to profit from the trading buys while allowing users to buy positive or negative shares regarding the outcome of a future event.
These are just a few examples of the many dApps that exist today. Each of these dApps serves different purposes and showcases the potential of decentralized applications. They represent a small fraction of what’s possible with this technology. As the blockchain space continues to evolve, we can expect to see more innovative and diverse dApps in the future.
What is the Future of dApps
The future of decentralized applications (dApps) looks promising and is expected to revolutionize various sectors. Here are some key trends and expectations:
Gaming: Blockchain technology provides an advantage in gaming, especially in terms of ownership. The current Web3 gaming market is characterized by play-to-earn games, which appeal to players in developing economies. With the large amounts of investments into the blockchain gaming industry, we can expect increasingly higher-quality gaming projects.
Identity: Blockchain enables the creation of portable digital identities (DID), which allow users to effortlessly transfer information and assets across different networks and chains. This technology empowers individuals by allowing them to truly own their data and retain privacy.
Launch of More Stablecoins: We can expect to see more stablecoins in the future. Developers creating blockchain-based decentralized applications can expect to create more apps around stablecoins. Stablecoins intend to solve the problem of volatility in the cryptocurrency market.
Decentralized Exchanges (DEXs): Decentralized exchanges will likely become more important. Developers of dApps can expect to create more DEXs.
