Start Your Blockchain App Development Journey Right Now! A Beginner’s Guide

One of the most famous and secure systems for communicating and transmitting essential data and information can also be utilized in application development. This solution, which enables a complete beginner to this technological category, begins with defining the term “blockchain” itself, as many don’t yet recognize the conceptual idea behind this technology.

In simple terms, “blockchain is a simple, decentralized, transparent, immutable, and publicly accessible database which stores digital information in Blocks, that are then paired with each other, using hash functions in such a way that the previous block will have the hash function of the present one and so on.  

When looking at this definition from the business perspective, we understand that it’s a network for transmitting and exchanging certain specified communicational values. It is a method that enables peer-to-peer transactions without the involvement of a third party or a middleman. Now that we understand the basic concept of what a blockchain is, let’s enter the vast world of what a blockchain is capable of in application development. So, without any further ado, let’s get into it.   

Crafting Blockchain Applications: Follow These Steps! 

The first and foremost action to take when developing any application is to determine the purpose and concept behind what the application will provide and what it will be capable of doing. In short, the first step is to decide the application’s scope, structure, and purpose. Once we’ve completely solved the concept behind the purpose and scope of the application, we will start the process of its development by following the steps given below: 

Step 1. Developing The Blockchain Development Idea: 

The foremost action to take when developing a blockchain-based application is to determine and define the application about its purpose and meaning. Understand that even if you’re willing to protect and secure a medium-sized application, you should first calculate the required amount and compare it with the estimated profit you’re going to make through the development of the application and ensure that going through the entire process is factually worth it. You’re not doing this for any lesser means. 

Once you’re done recognizing the approach you want your application to take, you must now discover the use –cases for your application and deduce if your application requires the support of blockchain. It’s pertinent to understand that blockchain is a method of securing data through encryption and integrating peer-to-peer transactions of information. If, for some reason, it’s not initiated correctly, it will not ensure the greater transaction security you’re doing this for.  

Companies that wish to build a supply chain based on blockchain to maintain their sales must first understand the application’s use cases and how it will further help the company grow and benefit the business-consumer relationship. 

Step 2. Identify The Suitable Blockchain Platform:  

Now that you’ve successfully determined your application’s need to be based on blockchain, you must choose the suitable technology to adopt and integrate into your application.   

Constructing Your Own Blockchain Framework:

What you can do to initiate the developmental process is construct your own blockchain framework by choosing everything regarding your application’s developmental requirements, starting from transaction validation algorithms to the token transaction fees. Understanding the fact that the developmental process is quite extensive to approach is pertinent, but don’t forget that it’s quite expensive to undertake as well. That said, if you’re thinking of creating a new Bitcoin or Ethereum, which might seem intriguing, it can impose a huge cost on you if ordained in the process. It can cost you thousands of dollars, and you will only opt for this opportunity if you’re willing to spend a hefty amount in the process and then if you create a blockchain application for your own cryptocurrency.  

Clone-Established Blockchain Applications:

Another more efficient method to rely upon when creating a blockchain-based application is to utilize the services of a proper blockchain platform. These platforms are open source. You have the choice to run the code on your own servers if you want to. You might be thinking about why the world would accept a blockchain established by you. The simple answer to this question is to always remember that the nodes of a network that can validate the transmitted transactions further determine the success of a blockchain platform. 

Each currency has unique traits to benefit from, and they might assist you in making your selection. That said, the most utilized platform is Ethereum, and it has the tendency to store both currencies and tokens according to the following points: 

  • Open-source and publicly accessible computing platform, and it also includes smart contract capability. 
  • It consists of a proof-of-work technique that is recognized as ETHASH, and it demands excessive RAM to make mining more difficult. 
  • Moreover, it also utilizes Solidity programming language to write smart contracts and can be introduced as a subset of JavaScript, Python, and C.

Using Coins On Today’s Blockchain Systems:

This differentiates from the previously discussed point that deduced copying the whole blockchain platform and then further running it on personal servers. However, we are also enabled to utilize the method of simply generating tokens and installing them on an already set and operational blockchain such as Ethereum.  

The reason behind them being ready to be used is that they include ready-to-use algorithms, APIs, and further mining techniques that enable you to quickly and efficiently integrate the elements of a blockchain and utilize the capabilities of the blockchain as a service provider. The reason is that ethereum tokens are accepted by a wide range of wallets, so you won’t feel the need to build a separate wallet, especially for your transactions.  

Step 3. Proto Development: 

Given the expensive costs of blockchain development and the extensivity of the process involving such development, it is best to create a prototype application first. Doing this will ensure the deployment on a server or a blockchain platform and will further determine if the application is performing according to how you planned or not.  

Next comes developing your choice over which part comes in the segment of “Off-Chain” and then which part comes in the “On-Chain” segment. What you need to understand before segmenting certain parts of your application is that when you’re developing your application, there will always be some capabilities that are easily operable on standard cloud hosting instead of integrating the blockchain in them. In addition, there will also be the transaction portion of the application, which will always be hosted and entertained by the blockchain, as it is essential for this capability and service of your application to operate. This is why it is critical to analyze your application’s capabilities and then inject the standard hosting platforms into your application to host certain specified capabilities of your app that are easily operable on it.  

That said, you should also analyze and determine if your application will be applied in a permission-based network or a permissionless network to operate. They can be explained as: 

1 . Networks With Permissions: 

Everyone is allowed to join and verify themselves. The most well-known platforms to work on permission-based networks are Bitcoin and Ethereum networks. 

2 . Network Access Is Disallowed: 

The network owner here determines the individual who may join the network in this situation. Moreover, only a few known members are enabled to join this network and authorized to verify blocks. In short, these procedures are more authority based. 

You should always keep your off-chain APIs in their own category and never allow them to temper the domain of on-chain APIs, as they will be hosted in different locations and platforms. Once you’re done choosing the transaction and consensus approach of your application, fulfilling the requirements of this step becomes much easier if you opt to operate on an established blockchain platform, for many features are already integrated into these platforms, and the overall experience becomes much smoother in comparison.  

Step 4. Development Of Your Blockchain App

This is by far the most crucial component of developing a blockchain application. Let us move forward while using tokens on currently applicable blockchain networks to keep things simple and easily understandable.  

Foremost, it is critical to comprehend the transaction process. For example, for crypto application development, tokens serve as a unique ID for the crucial development of your smart contract. Tokens are alphanumeric strings that are quite lengthy as well. The public and private keys of blockchain wallets are assigned uniquely to each user. When being utilized, these keys operate as the key to identifying users. This is much secure when put in comparison with declaring and adding a new beneficiary whilst using their bank account number in your own bank account. 

Step 5. Deploying And Maintenance of Blockchain App: 

You may enable yourself to develop your own Ethereum smart contract or token by yourself. You will have to first develop a test token to check its functioning before releasing your token on the blockchain. When creating your first Ethereum token, you should follow the instructions we have provided. You place the token on the chain after you’re done completing it, which is then like deploying and initiating your work on a server. 

When it comes to the initiation of a transaction, it first begins with one person sending out an intention of sending a token, which will then be deemed valid by the server.  

It is pertinent to mention here that your token information is conjoined with your private key. This then starts a digital code, which is further deemed to be valid by the network in use whilst using the sender’s public key, which is unique to that person. In addition, no association between the public and private keys is discoverable, which safeguards the security of the transaction being made.   

How Does A Blockchain Application Operate? 

Given that blockchain is a highly secured network that distributes all the data among its users and peers and stores the data in blocks in chronological order. This further states that when any disturbance is made within the data, all the peers with access to the data. For further clarification, you need to understand that these Data blocks are kept inside of a chain, and once the chain has completely forged, meaning once the data has been added inside the block, the data cannot be modified, and the chain cannot be remade. This factor demonstrates the idea of how secure the blockchain is, and this is what makes it quite difficult to breach and exploitation of data is completely secure. 

When setting up a blockchain, you’re going to need about a few gigabytes to a terabyte of storage space in order to fully operate and enable complete functionality of the application. These applications normally overtake only a portion of space on the blockchain as these mobile devices have limited storage. 

Two Major Types Of Blockchains Based On The Network: 

A permissionless blockchain is capable of being used on any device and is open to all network participants. Every user involved in the chain has access to its code and can actively check transactions and connect with others involved in the network, all while having anonymity.  

A permission blockchain, on the other hand, has rules to be followed by the parties involved. In addition, only authorized parties who are granted permission to indulge in this network can play a role in the network. This form of blockchain is ideal for establishing control and managing activities in a confined environment, such as within enterprises and other such systems. 


Every business wants to establish, develop, and maintain an app with blockchain capabilities. However, it’s not that easy to perform. With all the knowledge provided above, you can now establish and develop an application that fulfills your requirements and needs accordingly. Doing so only after first determining that your needs and wants can be fulfilled and serviced by the blockchain only, is your foremost duty.
