Decentralized applications, DApps, are fast becoming a norm, disrupting the old order, and setting the pace for a new era of applications that are free from the limitations of centralized systems. Learn the nature of DApps and other information about these unique applications in this article.
An Overview of DApps
A Decentralized Application or DApp is a computer program that runs on a distributed P2P network of computers rather than a single computer. DApps are built using blockchain technology, which provides an open-source transaction ledger and an immutable data structure. DApps run by interpreting coded instructions or smart contracts written in Turing complete languages that execute automatically without any third party involved.
DApps can be built on various blockchain platforms like Ethereum, BNB Chain, EOS, and TRON. They can be used for multiple purposes, including financial transactions, gaming, social media, etc.
Some key features of DApps include:
- Decentralized: DApps run on a decentralized network, meaning there is no central point of control or failure.
- Secure: Because a decentralized network powers them, DApps offer more privacy and are less vulnerable to hacking and other cyber attacks.
- Transparent: DApps are built on top of transparent and open-source blockchain technology, which means that their transactions and data are transparent and accessible to all users.
- Autonomous: DApps are autonomous and self-executing, meaning they do not require intermediaries or go-betweens to function.
- Incentivized: Many DApps use blockchain-based tokens or cryptocurrencies as incentives to encourage users to participate in the network and help to secure it.
DApps use smart contracts, self-executing contracts with the terms of the agreement between buyer and seller directly written into lines of code. They also have no central control point, making them less susceptible to censorship, fraud, and downtime. Transactions on a DApp are verified by consensus of the network participants rather than relying on a single trusted intermediary.
Overall, DApps have the potential to revolutionize various industries by providing more secure, transparent, and decentralized alternatives to traditional centralized applications.
Structure of DApps
Front-end
The front end is what users see, interact with, and use daily. It runs directly in a web browser or app, so there’s no need for downloads or installations before users start using it. This makes DApps much easier to use than traditional software products because there’s no complicated installation process to worry about.
Smart Contracts
Smart contracts are pieces of code stored in the blockchain that execute actions based on their logic and rules. They can be used to transfer Ether or any other cryptocurrency directly between two parties without using an intermediary like a bank or payment processor. Smart contracts can also store information about an application’s state, like user balances, orders, and other data related to its operation.
Back-end
The back-end is the server that processes requests from clients and returns a response to them. It can be written in any language supported by the virtual machine hosting your DApp, such as Node Js. for Ethereum DApps or Go for NEO DApps.
Blockchain
At the heart of every DApp is the blockchain. The blockchain is a decentralized database that contains all of the information associated with the application. It’s made up of blocks that store data and are connected sequentially to form a chain of blocks. Each block has a hash algorithm that links it to its parent block and a timestamp that indicates when it was created. These features allow users to trustlessly access DApp data without depending on third parties like servers. The only requirement to use DApps is an internet connection and some cryptocurrency, e.g., ETH or BTC, to pay for gas fees while transacting on a secured blockchain.
Examples of DApps
Some decentralized applications (DApps) include:
Cryptokitties: A collectible game built on the Ethereum blockchain where players can buy, sell, and breed virtual cats.
Augur: A decentralized prediction market platform built on the Ethereum blockchain.
Uniswap: A decentralized exchange built on the Ethereum blockchain that allows users to trade cryptocurrencies without the need for a centralized intermediary.
Steemit: A decentralized social media platform built on the Steem blockchain that rewards users for creating and curating content.
IPFS: InterPlanetary File System is a peer-to-peer method of storing and sharing media files in a distributed file system.
MakerDAO: A decentralized lending platform built on the Ethereum blockchain that allows users to borrow a stablecoin pegged to the US dollar using cryptocurrency as collateral.
Aragon: A decentralized governance platform that allows users to create and manage decentralized autonomous organizations (DAOs).
