Step-by-Step Guide to Implement Blockchain in Different Business Processes

Now that we have covered the basics of blockchain app development, let's take a look at the actual process of developing a blockchain application. This guide will take you through all of the steps necessary to get your idea off the ground and turn it into a working application.

Step 1. Define Your Idea

The first step in developing a blockchain application is to come up with an idea for what you want to build. This might sound like a simple task, but it is actually quite difficult to do. Remember, your idea needs to be both feasible and in demand in order for it to be successful. Spend some time brainstorming and doing market research until you have something that you are confident will be successful.

Step 2. Identify a Use-Case4

The first step in implementing a blockchain is to identify a use case. This will help determine which type of blockchain is best suited for your needs. There are three main types of Blockchain systems – public, private, and consortium. Blockchain platforms can be categorized as public (permissionless) like Ethereum and private (permissioned) like Hyperledger Fabric.

Public Blockchain

Public blockchains are permissionless, meaning anyone can join the network and start validating transactions. Public blockchains are decentralized and have high security due to a large number of participating nodes. The most popular public blockchain is Bitcoin, which uses a proof-of-work algorithm to achieve consensus.

Private Blockchain

Private blockchains are permissioned, meaning only those with permission from the network administrator can validate transactions. Private blockchains are more scalable due to their smaller number of participating nodes, but they sacrifice decentralization and security for this advantage. The most popular private blockchain is Hyperledger Fabric, which uses a proof-of-stake algorithm to achieve consensus.

Consortium blockchains

Consortium blockchains are a hybrid of public and private blockchains, where a group of pre-approved entities can validate transactions. Consortium blockchains strike a balance between these extremes, offering both decentralization and scalability. The most popular consortium blockchain is R3 Corda, which uses a voting-based algorithm to achieve consensus.

Once you have identified a use case, you can begin developing a prototype. This will help you test the feasibility of your idea and get feedback from potential users. After developing a prototype, you can move on to building a minimum viable product (MVP).

Step 3. Developing a Proof of Concept (POC)

Developing a proof of concept (POC) is an important step in the process because it allows you to test the feasibility of the proposed solution and see if it actually works in practice. There are a few things that you need to keep in mind when developing a POC for blockchain implementation. 

First, you must clearly define the problem you are trying to solve. 

Second, you need to come up with a solution that leverages blockchain technology to solve that problem. 

Third, you need to create a prototype of the proposed solution and test it out.

Once you have developed a POC, it is important to get feedback from others. This will help you refine the POC and make sure that it is ready for actual implementation.

Step 4. Choose Your Blockchain Platform

Once you have an idea for your application, you need to choose which blockchain platform you want to build it on. There are many different options available, so take some time to learn about each one and decide which one is right for your particular use case. Some of the most popular options include Ethereum, Hyperledger Fabric, and Corda.

There are a number of factors to consider when selecting a blockchain platform for your business. Here are some key considerations:

• What problem are you trying to solve?

The first step is to clearly define the problem that you are trying to solve with blockchain. Once you have a good understanding of the problem, you can start evaluating different platforms to see which one is the best fit.

• What type of application do you need?

There are different types of blockchain applications, each with its own set of requirements. For example, if you need a decentralized application (DApp), then you will need a platform that supports smart contracts.

• What is your budget?

Developing and deploying a blockchain solution can be costly. Make sure to consider all costs involved, such as license fees, hardware costs, and development costs. Also, keep in mind that some platforms may require ongoing maintenance fees.

• What skills do you have?
