What is Blockchain app development

Blockchain apps are decentralized applications. A blockchain has no server that acts as a mediator between users who exchange messages, data, or money. Blockchain applications are also called as DApps. This opens a lot of opportunities for many industries and that is why blockchain application development is very important for many industries.   

Simply blockchain is a sequence of blocks that provides immutable, share-data storage and append-only. Among users, blockchain facilitates decentralization. Blockchain also supports applications that require transparency and tamper evidence. 

Blockchain is the database which is subsisting on various systems across the world at a single moment. It continues to grow by adding new sets of recordings and blocks. Nevertheless, each block has any linked contact with the preceding one to form a chain. This is the most famous technology which has a broad scope in the future. Blockchain technology benefits to transferring data most securely and transparently. Blockchain development has contributed the most secure and effective way for industries to secure and decentralized systems, for recording and transporting the data. It also maintains money transactions. In short, Blockchain is the technology that increases any domain wherever some value is negotiated. These can be recorded as data, private information, transactions, and so on.

How do Blockchain applications work?

Before we go deep into blockchain applications lets see how blockchains work.

Blockchain is a network that shares all data among the user’s, stores this information in the alphabetical order in the blocks, this means if any new transaction occurs in the blockchain then it is shared with every member of the blockchain and every member has a record of it in their own devices.

Space required to set up the blockchain is few gigabytes to a terabyte of storage space since mobile phones don’t have that much space so blockchain applications normally function on just a part of the chain.

Based on the network type there are two types of blockchain they are as mentioned below.

Permissionless blockchain:

This is accessible to every member of the network and is accessible on any device, every user of that network can verify transactions, access the code, interact with others, and can still stay anonymous. For example, bitcoin is permissionless.

Permissioned blockchain:

This allows only authorized members. All participants have roles and permissions. A permissioned blockchain has protocols that activities transactions among network members. This type of blockchain is excellent for managing processes inside the organizations.

Operations on Blockchain:

  • Adding a record to Blockchain adding record is the easy and simplest blockchain operation each block contains data, a hash of data and the hash of previous data, adding a record to the blockchain means adding a record to the distributed ledger. This involves two things. First, we should validate the collected information about transactions that will be stored in the blockchain. Second, we should solve the crypto-puzzle which is also called work proof.
  • Login is the second core operation for a DApp Login needs the person who attempts to gain admittance to the system to confirm that they are the personality who they claim to be. This is accomplished via a technique called challenge-response protocol (also known as a Zero-knowledge proof). When executing a challenge-response protocol within a blockchain, the person’s Decentralized Identifier is stored inside the blockchain. The person demands he or she is the person registered with the DID by giving information, such as an email address, from the Decentralized Identifier to the blockchain. 
  • Share a Key Sharing a key is a moderately more advanced operation resembled the login use case. This can also be created by enlarging the login use case. For instance, in the login situation described above, the arbitrary value produced can be utilized as a secret key that can also be utilized as the shared key for interaction between the browser and the Ballerina API. This determines the chat communications exchanged between the browser and the Ballerina service is encrypted with the secret key.

Advantages of blockchain operations:

  • Public verification any user can check the working of the system, each and every transaction is validated by the users of the blockchain.
  • Transparency all day-to-day updates to data and transactions should be validated by the network users.
  • Privacy even if the blockchain id decentralized system all the transactions and interactions are anonymous    
  • Integrity blockchain assures no data is changed.
  • Easy transactions Many banks endeavor to give mobile services, but the transaction method, however, is not ideal in some cases because of the denied transactions, payments, and exchange rates. With DApps, this is not the case: it takes barely a few minutes to set up a blockchain folder, and let users buy things including the cryptocurrency without fees.
  • High security commonly used banking apps and confidential chats always strive for security mobile apps are unprotected and hackers can easily steal money using a man-in-the-middle attack during transactions. 

Steps to build a blockchain solution:

  • Identify a suitable use-case
  • Identify the Most Suitable Consensus Mechanism
  • Identify the most suitable platform 
  • Designing the nodes 
  • Designing the blockchain instance 
  • Building the APIs
  • Design admin and user interface
  • Adding future tech

Key industries using Apps:

  • Exchanges
  • Games
  • Finance
  • Health care
  • Real estate

Examples of Blockchain technology in practice:


  • KickCity:  Platform for event organizers that permits them to spend only for what they get, and pays association members by assigning those events. Their products create about $50k regularly with more than 70k users and 300 event managers.
  • Guts: A simple ticketing ecosystem that utilises blockchain technology to eradicate ticket duplicity and the subsequent ticket market.


  • Warranteer: A blockchain app that enables consumers to simply access information concerning the products they bought and get assistance in the case of product breakdown.
  • Loyyal: Powered by blockchain and smart contract technology, this support and pays platform generates numerous customized programs that indeed allot for multi-branded pays. 


Blockchain app or DApp is an abbreviated form for decentralized application, that can now be disposed of like a blockchain module. A decentralized app has its backend code which runs on a decentralized node-to-node network.

Utilize an open blockchain for your personal application. For instance, you can combine Ethereum or Bitcoin into your mobile. Create a single network with the help of blockchain software. Pick a blockchain as a service provider and combine their cloud service into your application.
