How to do Blockchain Application Development?

3. What are the Blockchain Apps?
Blockchain apps or DApps are decentralized applications which
mean there is no intermediator to control transactions between
the users. Whether it is an exchange of messages, money, or
data. Due to which, its possibilities of use in different industries
extended to the next level and it turns out to be a relevant
option for many businesses.
In a blockchain network, all the members behave like users and
mini-servers at the same time. They perform data verification
and its exchange within the network. To better understand the
working of the blockchain working keep on reading.

4. How DApps Work?
Before knowing the working of DApps, it is important to understand the working of
blockchain.
A blockchain is a network of members where all the data is shared among its
members. The data here is chronologically stored in blocks. Once any transaction
or data exchange takes place in a blockchain network, everyone will have a
record
or copy of this action on their own devices. These data blocks are associated with
a chain and once they are linked to the chain, no one can make changes to it.
That is why a blockchain is extremely volatile and hard to steal data from it.
Setting up a blockchain requires enough storage space (from a few gigabytes to a
terabyte). So one can’t develop a blockchain in a mobile device since it does not
contain that much storage space.
Blockchain can be classified into two types based on the type of network.
#1 Permissionless Blockchain
It is a kind of blockchain that is accessible to all the members of the network and
available to their own devices. Every member in the network has the right to
access the code, verify transactions and interact with others while keeping their
identity
unknown. Bitcoin is the perfect example of permissionless blockchain.
#2 Permissioned Blockchain
A blockchain that allows only authorized users known as permissioned blockchain.
In this blockchain network, every member has their roles and permissions. Not
even this, this blockchain is regulated by a definite set of rules for transactions
between the network members. The adoption of this kind of blockchain can be

5. What are the
Benefits of
Blockchain Apps?
Blockchain apps are gaining popularity since they offer an anonymous and secure
platform. Other than this, there is much more that encourages businesses
towards the adoption of blockchain technology.
Public Verification: Peer users of a blockchain who are also known as verifiers,
confirm each transaction. Through this mechanism, each user can check the
working of the system.
Transparency: In the system, every participant on the network can see data and
transactions due to a shared copy on each device. However, they are not
authorized to make changes to the data.
Privacy: Blockchain is a decentralized system with a higher level of transparency.
Still, all the interactions and transactions between network members remain
anonymous.
Integrity: There is surety with the blockchain that no data will be changed.
Easy Transactions: with the blockchain apps, it became easier to set up a wallet
and start transactions using cryptocurrency without any additional fees. Whereas
many banks face issues in the transaction process using mobile services and the
reason behind handling the rejected transactions, commissions, and exchange
rates.
High Security: Banking apps and messaging apps are prone to face security
issues. Since it is easier for hackers to enter the system through a man-in-the-
middle (MITM) attack during the transaction and steal money. Whereas with
Bitcoin,
there is no such risk of hack since all the data hereis decentralised and every
member throughout the chain shares a copy of the data.
Great Cryptocurrency Exchange Experience: Dealing in cryptocurrencies is quick and easier using mobile services. Besides,
the market is extremely volatile and witness frequent changes in prices. The cryptocurrency exchange development market has a
lot of potentials that increases the popularity of cryptocurrency exchange apps.

6. Step 1: Clarify your idea
Before developing a blockchain application for your business, it is
important to clarify the idea behind using blockchain technology. You
must be sure that your business requires blockchain in the first place
or not. After then think about the problems you want to resolve
through DApp going to develop.
Step 2: Do market research
Market research is a must before moving ahead with blockchain
application development. It will give you an idea of solutions available
in the market and what better you can offer to take a leap ahead in
competition.
How to Build a Blockchain App?
Step 3: Analyze your options
As per technical standpoint, there are four ways to develop a DApp for your business.
1. You can use open blockchain likewise Ethereum or Bitcoin for your own application.
2. You have an option of creating a private network considering blockchain software.
3. There is an option of BaaS (Blockchain as a Service) provider, you can choose any of the BaaS products from Amazon, Azure,
Microsoft and others. And can take advantage of their cloud storage with integration into your app.
4. You can opt for a blockchain network of your own, developed on the platform best suited for your business.
Step 4: Choose a platform
You can choose from more than 25 blockchain solutions building platforms available in the market. However, here we are
mentioning the top blockchain platforms which are commonly used for the development of blockchain apps.

7. Ethereum
Flexible and adaptable in nature, Ethereum is the first choice among blockchain app development companies for blockchain
application development. It is an open-source and public platform which allows the creation of ICOs with smart-contract
functionality other than blockchain dApp development.
Multichain
With Multichain, it became easier for mobile app developers to develop private blockchain solutions and its deployment within or
between multiple organizations.
Hyperledger
Like Ethereum, Hyperledger is also an open-source platform. However, it is used for the development of advanced blockchain
solutions. For example, one can develop IoT based blockchain solutions, blockchain apps for supply chain management and
more.
EOS
EOS platform aims at providing a blockchain solution that can offer smart contract functionality, decentralized application hosting,
and decentralized storage for the enterprise solution which completely eliminates scalability issues majorly seen with Blockchains
like Bitcoin and Ethereum. Along with it, it ends up the need of paying any fees from the users.

8. Quorum
Quorum is an Ethereum based open-source DLT and smart contract platform.
IOTA
IOTA is an open-source DLT based solution that is used as an ideal platform for the development of payment systems. And the
reason behind it uses a directed acyclic graph (DAG) and offers facilities like free transactions no matter what transaction size is,
handling of unlimited transactions at a time, faster confirmation times, etc. This ensures faster and secure payment services
between connected IoT devices.
Before choosing the platform make sure your development team possesses the necessary skillsets for that specific platform.
Since many platforms allow the use of conventional languages like C++, Java, Kotlin, and JavaScript for blockchain app
development. But there are others which use Solidity and Simplicity which are currently not that popular and only a handful of
blockchain app development companies can offer developers with such expertise.
If your blockchain application is built using languages like Solidity and Simplicity, there are high chances your development team
will face problems supporting the app in the absence of expertise. The team will be in need of learning new languages and the
principles of blockchain app development. However, these languages are way similar to the conventional languages which end up
trouble learning these languages to a great extent.

9. Step 5: Start the development process
The development process for your blockchain application can be different based on the following aspects
Platform and language you selected for your project
What strategy you are going to adopt for interactions and transactions among all the nodes
Your consensus mechanism
Other than this, one can also witness the diversity in the development process based on your choice for connecting with an
existing blockchain, using a BaaS, or go for creating an all-new blockchain for your own.
Whatever the case will be, the development process will encompass these stages.
• Business analysis: Here come the business analysts of the blockchain app development company into action. He will ask for
business goals, requirements and expectations from the project and then create a technical specification. This document will
contain every single detail required for the development process. Including the details of frameworks, libraries and operating
systems they are going to adopt for the blockchain app development.
• Design: The app project design can take from 8% to 20% of the complete budget based on its complexity.
• Preparation Stage: At this point, the developers set up a needed environment for the blockchain application development
likewise APIs, backend and architecture of the application.
• Development and Quality Assurance: Development and quality assurance steps of a blockchain app run simultaneously.
Means once the development of an application’s any section is completed, it will proceed for the testing and the later section
will enter the development phase and so on. After the completion of the development phase, QA performs rigorous testing of
the application to check if all the aspects are working properly or not.
• Deployment: After development, the blockchain application is deployed on the platforms like the AppStore and the Google
Play Store. If you want your blockchain application to become successful, it is necessary that it must follow all the rules and
regulations of the mentioned platforms. Also, keeping an eye over the performance data and user analytics is crucial for the
success of the application.
• Maintenance and Support: To keep up your application in the competition, it is crucial to offer the application timely
maintenance and support. It could include updates to libraries, framework and operating systems. Also, there must be a
requirement of the addition of new features and making changes to the application considering the current business needs.

10. Step 6: Deploy and maintain your blockchain app
Deployment is the final step of the development process. Once the product is ready and you have performed all the tests to
check its functioning. Your application is all set to hit the app markets like the Google Play Store, Apple App Store and others.
Now you will be able to see its performance and users’ response through user analytic data.
Maintenance is one of the most popular blockchain development services, a blockchain app development company offers. It is
necessary to maintain the functionality and security of the application. Also, a timely update for an application makes it compatible
with newer operating systems and libraries.

control over the development process. It is the right way to choose if your own business is software development. On the other
hand, hiring freelancers is least expensive as compared to in-house developers. But it is risk-taking working with freelancers. You
may consider freelance developers if the project is small. Because when the scope of a project grows the chances of risk factors
also increases with time.
Whereas if your project is large, it is good to hire a blockchain app development company. Not only will it cost lower as compared
to an in-house team of developers but also will support your project from time to time through its experience during the
development phase.

12. In the previous slides, you have gone through all the important related to the development of a blockchain application. Now the
question arises how can you use your own blockchain application to take advantages like improved security, increased revenue
and optimized digital business operations. Let’s have a look.
For Transactions: For transactions, basically, the typical gateways are great. However, if your target audience is aware of
cryptocurrencies, incorporating blockchain is the best way to offer fast, secure and easy cryptocurrency transactions for payments.
As a Distributed Cloud Storage: One can use its blockchain application as decentralized cloud storage. Rather than allocating
cloud storage for your application, it is better to choose blockchain technology and provide users with fast and convenient cloud
storage.
For Supply Chain Management: Supply chain mechanism involves exchanges of components between different entities. So
blockchain technology can be a great tool for keeping safe and permanent auditable records to look over the complete processing.
Authentication: A blockchain is a secure tool if you are looking for internal communication or operational management. Since it
offers unparalleled security and access only for the authorised users. Other than this, you get the chance of manipulating access
levels in permissioned blockchain.
