How To Develop a Blockchain Network

Today, we are going to look at what it takes to create a blockchain network on a dApp (decentralized application). The goal of this article is to give you the fundamental setup required to establish a functioning blockchain network that will allow you to start trading cryptocurrencies.

1. Identify the goal

Create a mission statement

Discuss the desired benefits

Will you use already finished code? Or do you need to start from scratch?

2. Choose the right platform

You need to identify which tools you need to create a blockchain network

Starting from scratch requires meticulous research and could take years to develop to completion, so build a dApp on top of an existing blockchain platform that meets your needs.

How to choose the right platform? Consider factors such as consensus mechanisms and problems you need to be solved.

3. Brainstorm session

After you find the right platform to suit your business needs, you should explore what other functions you need. What off-chain or on-chain systems do you need and how will they interact with the rest of your blockchain network? Will you run it on a permissioned or permissionless blockchain network?

Figure out which front-end programming languages you need as well as servers and external databases.

4. Proof of Concept

This stage concerns how you will prove the validity and agility of your application.

It involves two kinds of designs: a theoretical build-up and a design prototype. The theoretical buildup explains the programming theories used to create the virtual network. The design prototype is a visual demonstration of the network that should include sketches, mockups, the tested product, and software architecture.

Only after your client approves of your proof of concept can you move on to the visual and technical designs.

5. Visual/Technical Designs

For visual designs, outline a roadmap of fundamental solutions you need to complete a functioning network and draft the user interface model for each component. For technical designs, draft the API’s that will integrate with the UI and run a back-end


6. Development

Integrate APIs for specific user cases.

Formal testing (pre-alpha version)

Alpha version: developers test the application using white-box techniques.

Beta version: application has the complete feature set while still working to fix some minor bugs. The beta version will then be tested by people from outside your organization to test its user-friendliness.

Release Candidate version: an advanced beta version that is ready for launch.

Then the application moves on to the production phase to prepare for delivery/launch.

Deploy the application on a test network to ensure its viability.

After it is provisioned and approved, the application can be hosted on the main chain. If it is a hybrid solution using off-chain and on-chain business entities, it should be deployed on the cloud server and app store.

Even after the app is finally launched, it needs to be supervised by a team of professionals to ensure it keeps working as future updates/upgrades are applied to the network.
