The answer to How to develop a Blockchain application starts with what it even means.
Blockchain, in a layman’s language, is a decentralized, transparent, immutable and publicly accessible database where digital information (transactional record) is stored in blocks and are paired to each other with hash function, such that the current block has the hash code of the previous entry and the next block will have the hash code of the current block.
On the business side, it’s an exchange network for transferring value from peer to peer. It is a mechanism that authorized a transaction and makes it valid from the legal perspective, without involving middlemen.

Now, as you know what is Blockchain, let’s dig into the technical aspect of the technology, the meaning of Blockchain based application development, and ultimately the different prerequisites and the time and cost that would go into blockchain application development. All this starting with the blockchain types.
Types of Blockchain Systems/Solutions
The answer to how to develop Blockchain application starts with the categorization of the Blockchain solution type –
- Cryptocurrency support
Types of blockchain based on Networks
When talking about the blockchain development based on network, you can either go for Permissionless blockchain solutions or Permissioned blockchain solutions.
- Permissionless Blockchain: In permissionless blockchains, the whole network in publicly accessible on all the computers and devices. Anyone can access the code, start running a public node on the local devices, initiate an interaction in the network, verify the transaction, and that also while remaining anonymous. In short, the blockchain which is decentralized, equally accessible and anonymously available is said to be Permissionless. Eg: Bitcoin, Ethereum.
- Permissioned Blockchain: It refers to a closed ecosystem where only the authorized participants can act, based upon their particular roles. These types of blockchains are established on a set of rules that govern how a transaction will be implemented to cater the need of a particular organization (for eg: for database management, for auditing, etc.). Eg: Multichain.
This type of blockchain system provides core functionalities of the blockchain architecture, like automated data synchronization, immutability, ability to deal with multiple permissions, process automation, and stringent privacy and security features to name a few, and thus pave the way to build more efficient and data-driven business model at a lower cost.
Types of Blockchains based on Cryptocurrency Support
Based on the cryptocurrency involvement, Blockchains are broadly categorized as Cryptocurrency based and Non- cryptocurrency based solutions.
- Cryptocurrency based Blockchain: As depicted by the name, these types of blockchain solutions run based upon the cryptocurrencies. The popular types of blockchains that fall into this category are:
a. Wallets: These are secure digital wallets that hold the public or private keys with which one can send, store or receive cryptocurrencies. Also termed as Cryptocurrency wallet or crypto wallet, this blockchain type is mainly related to the conversion and trading of cryptocurrencies in a centralized, decentralized or hybrid scenario.
b. Crypto Exchange: These are basically the blockchain systems used to trade cryptocurrencies or digital currencies. They accept credit card payment, postal money orders and other forms of payment and send the cryptocurrency into your cryptocurrency wallet. They are also called as Digital Currency Exchange (DCE) systems.
c. ICO: Initial Coin Offerings (ICO) or Initial Currency Offering (ICO) is said to be a crowdfunding system that deals with the generation and selling of cryptocurrencies/crypto tokens.
d. Dapp: A decentralized app or dApp development services is one that deals with app that is not controlled by a single entity. It can be run by multiple users on a decentralized, P2P network in real-time with the help of trustless protocols. Augur, Golem and Sia are the best examples of what a dApp development company can bring into existence.
- Non-cryptocurrency based Blockchain: This type of blockchain app development services solutions do not depend on crypto tokens. Considered basically for inventory management, this blockchain type is based on Distributed Ledger technology (DLT).
Wondering what Distributed Ledger Technology is? From a technical perspective, it is a database distributed across various nodes and computing devices. Here, each node has a replica copy of the ledger and can process it independently. And the most impressive thing is that the ledger is not governed by any central authority.The changes can be made on an individual level and then the node is voted to gain maximum approval. This process of voting where the consent from the majority is necessary for making update is called Consensus. Once the consensus limit is reached, the changes are directly made across the database.
Blockchain Development Platforms
While there are more than 25 platforms for building blockchain solutions, the top blockchain platforms that are commonly considered for blockchain/DLT development are:-
- Ethereum: It is an open-source and public platform (and operating system) taken into consideration for blockchain dApp development and ICOs with smart-contract functionality. Unlike bitcoin, it is flexible and adaptable – making it the first choice for every blockchain app development company for building a blockchain app.
- EOS: The aim of EOS platform is to offer smart contract capability, decentralized application hosting, and decentralized storage of the enterprise solutions which solves the scalability issues found in Blockchains such as Ethereum and Bitcoin, along with eliminating all the fees incurred by the users.
- Multichain: It is a platform that empowers mobile app developers to create and deploy private blockchain solutions to be used within or between multiple organizations.
- LiquidApps: The name behind DAPP Network recently launched DSP 2.0 to make the platform a lot more flexible and powerful. They are capable of supporting a range of dApps creation.
- Hyperledger: It is an open-source platform used to create advance blockchain solutions. For example, building blockchain solutions based on IoT, creating blockchain apps for supply chain management, etc.
- IOTA: It is an open-source DLT based solution used for providing faster and secure payment services between connected IoT devices. This platform uses directed acyclic graph (DAG) technology and offers unique characteristics, like free transactions no matter what the size of the transaction is, faster confirmation times, handling of unlimited transactions at a time, etc. which makes it the ideal platform for building payment systems.
- Quorum: It is an open-source DLT and smart contract platform based on Ethereum.
Now as you are familiar with different blockchain development platforms, you must be confused how to choose the right platform for developing a blockchain system. To make it easy for you, here I’m sharing the factors you need to look out for when answering How to Develop Blockchain app:-
- Nature of Platform: While some blockchain platforms are cryptocurrency based, others are relying on smart contracts or using more than one crypto token. Determining which type is apt for you will make the Blockchain applications development process easier.
- Smart Contracts: The second thing you need to pay attention to is to determine if you need a smart contract or not. A Smart contract, as you might know, is a self-executing protocol that processes, validates or enforces any trigger-based action stored on the blockchain system.
- Consensus Protocol: Different blockchain development platforms work upon different consensus protocol, including Proof of Work, Proof of Stake, Proof of Elapsed time, Proof of Burn, etc. So, identifying the right platform on the basis of consensus protocol is also favorable situation.
- Cryptocurrency: The next thing that you need to consider when answering How to develop a Blockchain app is whether you need the use of cryptocurrencies in your mobile application or not also plays a pivotal role in finding the right platform.
- Public/Private Network: Ask yourself what kind of network you want – one where all are free to make changes or the one where authorized users only can participate. Based on the decision, choose the platform and start creating your own blockchain application.
Languages to Consider for Blockchain Development
Alike platforms, there are various programming languages that can be considered while blockchain application development. You can either begin with traditional programming languages like C++, Python, Go, and Java, or turn towards the advanced blockchain-specific languages like Simplicity and Solidity.
Assuming that you will be familiar with the traditional languages, let’s talk about Simplicity and Solidity only.
- Simplicity: Simplicity is used for smart contracts blockchain development. The language is easy, employ static analysis, and can be seen as an improvement of the basic cryptocurrency languages like Ethereum Virtual Machine (EVM) and Bitcoin Script.
- Solidity: Solidity is a statically-typed blockchain development languages used particularly for building smart contracts that run on the EVM. With this language, you can easily implement self-regulated business logic in smart contracts, leaving a non-repudiable and authoritative record of transactions.
Blockchain Development: How much time and cost do it require?
With all this information, you must be curious the most asked questions – How much will it cost to make a blockchain application? Well, it is quite difficult to tell the exact cost directly, provided the blockchain development cost depends on the efforts required.
For example, if you wish to develop a blockchain wallet, the average time required will be:-
Time required (in hours)
Frontend Development: Android
Front-end Development: iOS
Front-end Development: Web/Desktop App
Quality Assurance/Project Management
Likewise, if you build any other blockchain app/system, the time and efforts required will be:
Time required (in hours)
Smart Contracts + Token Issue
ICO Full Service
With this reference, it might be easier for you to get an estimate of the funds you need. However, don’t treat as your final quote. The blockchain app development cost varies on the basis of different factors. So, it is better to discuss your app project with a blockchain app development company and find out the exact Blockchain app development cost breakdown structure.
But before you even move on to have that discussion, see if Blockchain is even used in your industry.
Here’s a list of Industries in which Blockchain has proved to be of maximum use.
