Technology is reshaping the financial landscape and offers a wide range of use cases for decentralized app development. Because of transparency, readability and scalability DApp trend is spreading like wildfire. Ethereum blockchain is a main platform for building decentralized apps. Whereas, according to study, games and data storage are leading DApps categories. So what are decentralized apps? How are they different from regular apps? How to develop decentralized apps? Let’s see everything about the DApps.
What Is Decentralized Apps?
Decentralized apps are software applications without any central authority. But, unlike traditional applications that rely on a client-server network- maintained and authorized by a rule, they operate on peer-to-peer or distributed network. As there’s no one to control, dapps are less likely to be shut down by anyone or undergo downtime. Decentralized applications always builds on decentralized network. The network combines a smart contract and a frontend UI. On ethereum, smart contacts are transparent and accessible like open-source APIs, so you can include a smart contract written by someone else. Backend code of dApp’s runs on a decentralized peer-to-peer network, unlike regular app where backend code runs on decentralized servers. You can develop the frontend and user experience and interface similar to normal apps, making calls to its backend.
Decentralized Apps Vs Normal Apps-
1. Centralized Vs Decentralized-
Basic difference between Dapps and normal apps is decentralization’s root principle. Contrast to traditional apps that are controlled by centralized regulating authority, DApps operate on peer-to-peer blockchain network.
2. Security-
DApps are built using the blockchain platform so they are more secure as compared to regular mobile apps. Also decentralized apps tend to be tamper-proof, and the saved records are unchangeable. They are hacking and potential destruction resistant.
3. Value Storage-
Store value of DApp is one of the best features. It can store cryptocurrency and hand it to users once fulfilled the contract conditions. In contrast, traditional apps have to use a reliable third party to guard financial transactions. As you can store value directly inside the app, DApps eliminate any third-party requirements.
4. High Synergy Level-
When it comes to synergy, decentralized apps get the upper hand as they integrate seamlessly. As all the blockchain powered apps are inter-compatible, their synergistic possibilities increased in contrast to conventional applications.
5. Transparency-
Another difference between decentralized and normal apps is unchangeable public ledger. Unlike any other app, data or operations on the DApp are recorded in the blockchain and stay there forever unaltered.
Benefits Of Building Decentralized Application-
1. Zero Downtime-
Once the smart contract is deployed on the blockchain, the network will start serving its client. These contracts powering dapps operate 24/7, and till the blockchain harbor the contracts, they continuously perform smoothly.
2. Resistance To Censorship-
As dapps are not controlled, no one can block or keep users from submitting transactions or reading data from the blockchain.
3. Privacy-
You can secure transaction between users without sharing data using public and private keys.
4. Complete Data Integrity-
DApps don’t have a central point of failure, and stored data is unchangeable due to cryptography primitives. These features make it hard to hack teh chain and control a decentralized application.
Apart from all these advantages, DApps offer the following advantages.
- More security than client/server networks
- No intermediary for app control
- Cannot change written blocks without agreement of entire network
- Tamper-proof record of entire database
- No downtime
- Increased reliability
- Simple for payments
- Single outage/attack cannot halt it
Types Of Decentralized Apps Development-
1. Type 1:
In this type 1, you can create your own blockchain to develop your decentralized app. Bitcoin is an example of this type. Any other cryptocurrencies having their own blockchain comes under this category.
2. Type 2-
The type 2 dapps supports the blockchain created by type 1 applications. Those apps need to use tokens to operate their applications.Consider, Omni protocol, for instance, It’s built as the layer over Bitcoin, allowing you to create, send, redeem, pay dividends to and make best with the tokens representing any type of asset.
3. Type 3-
This kind of dApps makes use of the type 2 protocol to underwrite their tokens. Safe network is an example of type 3 dapps. SAFE(Safe Access For Everyone) is an open-source, decentralized data storage and communications network. Programmers create censorship-resistant websites and apps using the SAFE API.
Most Common Platforms To Create Decentralized Apps-
1. NEO-
It is a centralized, open-source blockchain that creates smart economy. It is called as Chinese Etherum and provides better options for scalability in dApps than other blockchain platforms. Currently, NEO is less popular than Etherum with just about 100 dApps built using this technology. Also, it is expensive and costs higher than Etherum in some cases.
2. Etherum-
It is the most popular decentralized, open-source blockchain used as the base for many blockchain project, including more than 2500 dApps. In terms of market value, Etherum is the only second to Bitcoin. Etherum also has a native cryptocurrency called as BTH- version of Bitcoin. Though it’s a bit expensive, it is a great option for creating dApps.
3. TRON-
It is a new blockchain platform as compared to Etherum or NEO. BUt it is popular and may even become a competitor to ethereum in the future. TRON is popular for gaming apps and gambling sites. Near about there 1500 dApps created using TRON that makes it great choice.
How To Develop A Decentralized Appli?
1. Decide Use Case-
Blockchain offers advantages like immutability, encryption, distribution, decentralization and tokenization etc. First of all, you need to analyze the problem that you want to solve and know if the solution really needs decentralization, encryption or any blockchain components. This step clears whether you need to develop a dapp. And if needful, which kind of decentralized app you should create.
2. Decide Technologies-
When you are finalized to create a decentralized app, list out the required technologies for development.
- Frameworks
- Database
- Hosting
- Frontend
- Frontend Contracts
- Contract’s programming language
- API’s
- Development server
- Features of dApps
If you create dapp using Ethereum, it’s standard kit for dapp development includes the Truffle suite of software with Ganache(BUILT-IN BLOCK EXPLORER), programming language solidity and Remix IDE.
As for the front-end part, you can use suitable technologies like React.js, Node.js, Swift/Kotlin or React Native for mobile and Web3.js for the web.
3. Front End Development-
Just like any application, decentralized apps need to have a client-side mobile app or website. Hence it is important to create an attractive UI that helps user to understand complex information quickly. Following approach is the best to achieve a user-friendly app UI/UX for any type of app.
- High-fidelity UI with prototyping
- Low-fidelity UI with wireframing
- User testing
- Shore up the UI/UX based on feedback.
4. App Coding-
To create a robust backend, you should hire app programmers with a strong knowledge of decentralized app architecture and workflow. Programmers should be familiar with building and deploying smart contracts on a network.
5. Testing & Launching –
When a decentralized app is ready to take off from the ground, you want to release it on the network.
With this, you get the opportunity to analyze the code rigorously and fix bugs and errors before making it public.
