Architectural Insights of Decentralized Applications

When you hear about DApps, what’s the first thing that comes to mind? 

Some fancy terms for the next-gen apps, right? You are somewhat correct, as DApps are considered new-generation applications that differ from their traditional counterparts in many aspects. 

So, let us explain DApps in layperson’s terms. A centralized entity does not control these apps; you have the power to control them. DApps are operated mainly by smart contracts based on blockchain technology – giving you much more control over your data. 

These apps offer more freedom and a sense of ownership since no one controls what you see or choose. For example, when you use a social media platform, you use their service for free, but you are the product that they profit from. They leverage your browsing history and preference to show you targeted ads and even sell your habit to third-party services without directly informing you. Likewise, in finance, when you take a loan from a bank, the institution serves as an intermediary that facilitates your loan by borrowing it from a depositor. For this service, they charge you a meagre fee and interest rate. Although the depositor receives interest from the loan, the bank takes the most of it. Now, Dapps can directly provide you with a P2P lending & borrowing platform where you can take a loan directly from a lender and negotiate your interest rates & repayment schedule without paying any charges to anyone. The exciting part of the decentralized exchanges is that it is wholly carried out by smart contracts, making the automated transaction error-free and convenient. 

How Come DApps? 

Trust us when we say that the history of DApps was laid down on a piece of paper. All of the early concepts of building decentralized applications were based on Vitalik Buterin’s Ethereum vision. In 2013, when he proposed a network aiming to achieve a decentralized way of life, he envisioned a blockchain-based internet where users like us held control, not corporations. Ethereum introduced smart contracts – immutable if-then statements coded into the blockchain to fulfil his idea. Following the Ethereum triumph in 2014, a report named “The General Theory of Decentralized Applications” was published by industry experts. 

So, as per the paper, for an app to be recognized as a decentralized application, it must possess the following characteristics: 

• Open-Source Development: DApps operate on publicly verifiable code, fostering trust and transparency. This allows you to inspect, contribute to, and understand the DApp functions. 

• Community-Driven Governance: DApp users actively participate in decision-making. The community submits and votes on changes, ensuring a democratic and user-centric approach. 

• Immutable Public Ledger: All DApp data and transactions reside on a secure, transparent blockchain network. This public accessibility guarantees the immutability and verifiability of information. 

• Distributed Infrastructure: DApps are not reliant on any single entity for control or operation. This distributed nature eliminates central points of failure and censorship. 

• Utility Tokens: DApps often utilise cryptographic tokens to facilitate access, incentivise participation, and reward contributors. These tokens can serve various purposes within the DApp ecosystem. 

• Consensus Mechanisms: DApp token generation and network maintenance rely on robust consensus mechanisms like Proof-of-Work (PoW) or Proof-of-Stake (PoS). These mechanisms ensure security and distributed ledger agreement.

Why the Need for DApps? 

Apps operating on a centralized network are inferior to decentralized apps. The main benefit of the novel smart contract is the absence of a third party. Sending money to anyone via an app like Venmo is possible, but a fee is associated with transferring the cash to a bank account. Furthermore, it frequently takes days for fiat to move. However, using decentralized apps to send money implies no charges or very little. You benefit from lower costs and time savings because decentralized transactions happen in the blink of an eye. 

We will give you the top 5 reasons for the need for DApps: 

• Trust: DApps run on a decentralized network instead of conventional centralized apps. Their distributed architecture and transparent code remove the need to put your faith in a single organization or authority. By directly verifying transactions on the blockchain, users may increase trust. 

• Control: When you use a DApp, you have more control over your data. Your information is not accessible to a single entity. Instead, the network functions as a whole, guaranteeing openness and lowering the possibility of data exploitation. 

• Innovation: DApps provide developers access to new opportunities. They can develop cutting-edge apps that use blockchain functionalities like smart contracts, allowing for safe, automated transactions without intermediaries. 

• Security: DApps are more difficult to attack by nature. Their decentralized architecture makes them less susceptible to malicious attacks or single points of failure. Furthermore, smart contracts reduce risks by enforcing predetermined guidelines. 

• Access: DApps make things more accessible. Participation is open to everybody with an internet connection, regardless of geography or background. This inclusivity empowers users and promotes an open digital ecology. 

Examples of popular DApps 

• Uniswap V3: A leading decentralized exchange (DEX) where users can swap cryptocurrencies directly without intermediaries. Uniswap uses automated market-making (AMM) algorithms for liquidity provision. 

• Compound: A lending and borrowing platform that allows users to earn interest by supplying assets or borrowing against their holdings. It operates on the Ethereum blockchain. 

• Axie Infinity: A blockchain-based game where players collect, breed, and battle fantasy creatures called Axies. It combines gaming with non-fungible tokens (NFTs). 

• Chainlink: A decentralized oracle network that connects smart contracts with real-world data. It ensures reliable data feeds for dApps. 

• Aave: A decentralized lending protocol enables users to earn interest on deposited assets or borrow against them. It offers variable and stable interest rates. 

• MakerDAO: A stablecoin platform that issues DAI, a cryptocurrency pegged to the US dollar. Users can lock collateral (usually ETH) to mint DAI. 

• Decentraland: A virtual reality metaverse where users can buy, sell, and build on virtual land parcels. It’s like a decentralized version of Second Life. 

• Synthetix: A platform for creating synthetic assets (synths) that track the value of real-world assets (e.g., gold, stocks) on the blockchain. 

• SushiSwap: Another DEX similar to Uniswap but with additional features like yield farming and staking. It rewards liquidity providers with SUSHI tokens. 

• Rarible: An NFT marketplace where artists and creators can mint, buy, and sell unique digital assets. It empowers individual artists in the crypto space. 

Final Thoughts

DApps are essentially an evolutionary shift in how we view digital interactions and software applications. Unlike conventional, centralized apps, they are based on the values of decentralization, transparency, and user empowerment. Through smart contracts and blockchain technology, DApps provide security, control, and creativity that are difficult to obtain with traditional apps. 

DApps should become more advanced and widely used as the blockchain ecosystem develops. They have the power to completely transform several industries, including supply chain management, social media, gaming, and finance. The secret to their success is the community-driven methodology, in which developers and users work together to design, manage, and enhance the apps. 

The era of decentralized applications offers fascinating potential and a glimpse into the future of digital interactions. Whether you are a tech enthusiast, developer, or user of DApps, the power lies with you!
