Building with CSC

Blockchain Development on CSC: Part2

Do you know Decentralized Applications (dApps) play a crucial role in bringing the applications of blockchain into action? Let’s dive in to learn the concepts of developing dApp (decentralized application)!

Over the course of time, blockchain technology has turned into a promising foundation for enterprise applications across different industries. Blockchain has many more functionalities, and decentralized application helps in expanding the uses of blockchain. With the global blockchain market slated to achieve the $69 billion mark by 2027, it is quite reasonable to think about decentralized apps or dApps

Previously, we got introduced to DApp development. In the first segment of this article, we became well familiar with Decentralized Applications and all there is to know about DApps. Now we take a deeper dive into DApp Development, how we can build and deploy our very own self-made DApps.

Before we get started with the main steps of DApp development, there a few key concepts to have in mind:

• Identify the Problem

First, it’s imperative to identify the problem you need solving or, in other words, the use case for your future DApp. Start by outlining the difficulties you face and assessing whether a decentralized application can help with them.

Do you want to remove third parties from your transactions? Or, perhaps, you’re looking to distribute information and services away from a central location? Either way, the first step is to figure out what problem a DApp can solve for you.

• Create a Proof-of-Concept

Next, you need to create a Proof of Concept (POC) to validate your idea and showcase its feasibility. Overall, it will help you test your DApp with minimal resources before committing a large amount of time and money to the development process. Take this step seriously, as it can help you identify pain points and areas of improvement.

• Pick a DLT Platform

If your POC is successful, it’s time to start thinking about execution. Since there are various platforms for DApp development, you need to determine which one will work best for you. Each blockchain platform has its advantages and limitations, hence you need to spend some time figuring out which will suit your requirements.

Currently, CoinEx Smart Chain — CSC is likely the most fitting option thanks to its smart contract capabilities and high efficiency.

• Develop and test the DApp

After picking a DLT platform, you can go ahead and get started with developing and testing your decentralized app. Whether you choose to turn to custom application development services or build through an in-house team, make sure the DApp undergoes thorough testing. After all, you don’t want to launch your new software and face issues that could have easily been prevented.

Beginner’s Guide to DApp Development

1. Learn Solidity
2. Get your Blockchain: CSC
3. Communicate with the Blockchain
4. Code Smart Contracts
5. Deploy Smart contracts

By now, you are probably wondering how to make a DApp and what the development process looks like. Creating decentralized applications is quite different from other custom software development, so let’s take a look at each of the steps below.

1. Learn Solidity — Solidity is the proprietary language to write smart contracts. It’s a feature-rich language specifically designed for this purpose, and this high-level programming language was inspired by C++, Java, Python, and JavaScript. A DApp can have its frontend code in any language, but the backend code must comprise smart contracts, hence this learning is also non-negotiable for a new DApp developer.
2. Get your Blockchain: CSC — This next step is very vital, as the blockchain is the foundation on which DApps run and selecting the right blockchain is equally important. While there are many clients the developer can choose from, we recommend ‘CSC’ for a new DApp developer, as its very user friendly and eliminated the problem of cost expense. CSC has Extremely high efficiency and low transaction fees. With the POS consensus protocol, CSC generates a block in seconds, supports extremely high TPS, and keeps transaction fees at a low level in the meantime.
3. Communicate with the Blockchain — The easiest and most common tool to communicate with the blockchain is ‘web3.js’. Installing it is easy, and there are specific instructions to configure the necessary parameters, for e.g.:

• Configuring the acongig.js file.
• Configuring the web3 API functions, for communicating with the blockchain.

4. Code Smart Contracts — A developer coding smart contracts must follow the following broad guidelines for effectiveness:

• Keep the computing logic and storage requirements minimal, because executing smart contracts require ‘gas’, i.e., a measure of computing power. It isn’t free, a certain number of crypto tokens must be paid.
• The code must avoid complexity, because the more complex the code is, the higher is the likelihood of errors. The outcome of a smart contract is irreversible, hence coding simple error-free smart contracts is imperative

5. Deploy Smart Contracts — The tool suite recommended for this is ‘Truffle’. It has the following advantages:

• A directory allows the developer to maintain all their smart contracts
• The tool can easily blend into the testing framework because the scripts can deploy the contracts in the test environment, run the ‘truffle test’, and run regular tests.
• Deployment using this tool suite is easy, and the required parameters can be easily set in the config.js file. Testrpc must be running in a separate window the deployment to work.
• Invoke the smart contract: Calls to the smart contracts must be in hexadecimal strings.

Launching your DApp

Finally, after developing and testing, your DApp is ready to launch! Remember to be extra careful when launching on the production server since there is no room for errors. As you recall, it’s hard to make changes once the application is deployed, so don’t rush the process.

These are high-level steps, so as you can imagine, the technical side is a lot more complex. Just keep in mind, you don’t have to go at it alone and figure out how to build a DApp yourself. Instead, consider turning to the CSC Ecosystem to get help with your blockchain-based DApp development.

Hands on With the Blockchain: Getting familiar with CSC

About CSC — Based on CPOS consensus protocol, CoinEx Smart Chain (CSC) is a smart contract chain that supports up to 101 validators. Aside from shorter time for block generation and lower fees for transactions, CSC is also fully compatible with Ethereum virtual machine (EVM) and protocols while supporting high-performance transactions. Meanwhile, CSC adheres to the principle of decentralization and permission-free so that anyone can stake coins and become a validator.

CSC Features

• Decentralization: Permission-free, anyone can become a validator by staking CET.
• EVM compatibility: Fully compatible with Ethereum virtual machine (EVM), which means that almost all DApps, ecosystem components and tools on Ethereum can be migrated to CSC directly or with very small changes.
• High performance: 600+ TPS, 3s block time

Wallet

Software to manage accounts. Used to access and control CSC accounts and interact with Smart Contracts. Keys need not be stored in a wallet and can instead be retrieved from an offline storage (e.g., paper) for improved security.

About CSC Consensus

CoinEx Smart Chain adopts CPOS consensus protocol.

CPoS Consensus

Although Proof of Work (PoW) has been proved to be a practical solution for decentralized networks, yet it is not environment-friendly and requires a large number of participants to maintain network security. PoA protocol on the other hand is not decentralized enough, for the validators are prone to corruption and security attacks given the extreme powers they possess.

After rigorous investigation and research, CoinEx Team adheres to the principle of decentralization and combines the characteristics of PoS with PoA to realize CPoS, without losing network stability and security. The features of CPoS are as follows:

1. Blocks are generated with a maximum of 101 validator nodes.
2. Anyone can become a validator by staking CET without any permitted.

3. Anyone can stake for their trusted validator.

Resources CSC provides.

Remix

Remix is an online tool for contract development and deployment.

Remix IDE allows developing, deploying and administering smart contracts for CSC like blockchains. It can also be used as a learning platform.

Truffle

Truffle is a powerful tool for contract development assistance.

Truffle is a tool that makes it easier for developers to build blockchain-based Dapps on Ethereum.

Smart contracts vary — and the type of code required — from network to network. Ethereum, for example, uses its own programming language, called Solidity, so developers have to learn a new language to code on it. Other networks have their own versions. Truffle helps deal with these problems by allowing developers to code in languages they already understand languages like JavaScript and JSX.

key features of Truffle?

• Home for developers to build Dapps.
• Ability to test smart contracts.
• Connection to cryptocurrencies using the Ethereum Virtual Machine.
• Support for custom build processes
• Ability to deploy to many public or private networks.

The impression of the journey to becoming blockchain developers shows that the destination is not impossible to achieve. With the right set of skills and guidance in your journey, you can discover how to become a blockchain developer with ease. However, it is also crucial to develop the basic skills required for blockchain developers and understand the reasons for becoming blockchain developers.
