When the blockchain configured properly, it can provide a decentralized solution that reduces the number of intermediaries, increases transparency, and ensures data security and eliminates unauthorized access at the same time. Thanks to this, this technology can be used as a replacement for the traditional base when creating an application architecture
for Android and iOS. In this article, we will look at how to create such an application. We also advise you to carefully read our article about TOP 5 BLOCKCHAIN TRENDS OF 2022
Step 1. Defining the idea

As with any product, an idea is the first thing you need to think about before you start developing your application
. At the same time, you must be sure that you really need a blockchain to implement it. So, if you want to create a mobile video game, torrent client, online magazine or aggregator of something, then the blockchain is not needed here, since it does not bring any advantages compared to the traditional approach.
Blockchain technology will be useful in the following cases:
- If the mobile application will work with users' money: payment gateway, insurance service, online store, charity. Blockchain and smart contracts will be able to ensure the honesty and reliability of transactions, reduce transaction fees and the number of intermediaries.
- If you want to build the trust of your users. This is important if you are creating a blockchain application on Android and iOS with a voting function, for example, for primaries, election of the organization's leadership, or where and how to spend charitable funds. Blockchain is able to provide transparency and verifiability of such plebiscites without disclosing the secret of the vote.
- If you need to automate business processes. With proper implementation, smart contracts can automate more common tasks related to document flow and payments. For example, smart contracts are already being used to automate customs clearance, in real estate transactions, as well as to track the origin of goods.
- If you need the most reliable identification system and / or verification of something. For example, blockchain has shown its usefulness for personal identification, real estate registration and copyright.
- When you need better protection of confidential data. The simplest example is the protection of a patient's personal data when communicating with a doctor.
Step 2. Finding a technical partner
Once you have decided what kind of blockchain applications on Android & iOS you plan to create
, your next step is to find a developer. You need a technical partner, because creating a mobile application
on the blockchain using templates, as is the case with WordPress sites, will not work. Blockchain requires certain knowledge and skills, and also costs 15-30% more.
What to pay attention to when looking for a technical partner is described in the article: «How to choose a software company
Step 3. Choosing the optimal platform

At the next stage of creating a mobile blockchain application
, you need to decide on which blockchain network you want to create your product. The choice must be made based on what properties you need.
Here are some of the most popular options among developers:
- Ethereum is the most popular option that will allow you develop a blockchain application and create your own ecosystem using the Solidity programming language. Suitable for most projects that rely on decentralization, transparency and security.
- TRON is a free global financial system that allows you exchange tokens or digital content in an easy and cost-effective way. For example, game items in online games or movies and TV shows on Netflix. The peculiarity of TRON is that its blockchain allows you to make such exchanges instantly and with a very low commission, thanks to which even trade transactions for $ 1 will be profitable
- IOTA is an open source distribution ledger for the Internet of Things that uses a directed acyclic graph instead of the traditional blockchain (DAG). Provides features such as commission-free transactions, processing unlimited transactions at a time, faster confirmation time. This enables faster and safer interactions between IoT devices.
- R3 Corda - J.P. Morgan for the banking sector. Its main feature is simple and fast integration with outdated systems (large banks, as a rule, use rather old software).
- EOS is a platform focused on solutions that rely on smart contract functionality, decentralized application hosting and decentralized storage for an enterprise solution that completely eliminates scalability issues.
Step 4. Development of the application framework

The process of building a blockchain application on Android & iOS is similar to the process of building a house. Before you start laying the foundation, you need to develop an architectural plan that will give you an idea of what kind of house and what you will be building of. The framework of your application is the same architectural plan that you will use to build your software product.
Frameworks depict the basic structure of an application, its appearance, user path, approximate appearance of application screens, and so on. With such a scheme, developers can understand what functionality they need to implement and how long it will take them to do so, which helps to budget the project.
Frameworks development usually requires two steps:
- Creating a low-precision framework. A rough, schematic sketch to help you quickly get an idea of the basic structure of your application. Most people learn such visualization easier than the presentation of the project in the form of text, tables and diagrams.
- Creation of a high-precision framework. In such a scheme, annotated blocks are replaced with images, ready-made articles (texts) and links.
Step 5. Creating the user interface

Once the framework has been created, you can start developing an attractive user interface for your blockchain application. This is a very important stage, since the user experience will depend on it - how the user perceives the interface: pleasant colors, convenient icons, intuitive transitions between screens. Or vice versa: it is not clear what and how to do, small icons that cannot be hit, some kind of toxic color scheme.
Here's what designers should do at this stage:
- Define the style. Several sets of images (moodboards) are being prepared, which show application screens with different color schemes, font compositions, buttons and illustrations. These images are sent to the customer and / or the focus group, which chooses the nicest and the most appropriate for niche.
- Create a design concept. It is intended to show you what the finished application will look like. If the previous stage gave only a general direction, then the concept is designed to cross this direction with filling the interface (high-precision framework). Usually, for this, they make a complete design of 1-3 screens of the application, after which they are sent for approval.
- Design all the screens. If the concept is good, designers proceed to finalization of the appearance of the interface, which results in a complete schematic structure of all interface screens. Then all screens are assembled into an interactive prototype, which gives the most approximate experience of using the application without implementing it in code.
- Create interface animation. During this stage, designers define how icon clicks, screen transitions, video / image opening, etc. will look like. Usually animation is done using Adobe Photoshop or another tool, and then videos are made from this. The customer needs videos to understand how the animation will look in the final version, as well as developers who will be guided by these videos when implementing the design and functionality of the application in code.
- Prepare materials for developers. After completing the creation of the interface, the designers send the developers sprites, fonts with all icons, a UI Kit with repeating interface elements and their states, as well as all other materials with documentation.
Step 6. Implementing the application in code
After designing the UI / UX, the process of implementing this design and application business logic in code begins. This usually means implementation at the background (backend) and foreground (application interface) levels. This process may look different depending on several aspects:
- What language and platform do you choose for your project.
- Whether you using BaaS or creating your own blockchain.
- Strategy of communication and transactions between all nodes.
- Selected blockchain consensus mechanism.
- Which SDK APIs are you using.
This usually involves creating a minimum viable product (MVP), which is used to validate the concept and receive feedback. With this data, the product is being finalized to the release version.
Step 7. Testing and verification
Thorough testing of your blockchain application is one of the prerequisites for developing blockchain applications if you intend to add your product to the listings of the Google Play Store or Apple App Store. These sites necessarily require that the app be tested based on various parameters and criteria, be free of errors (critical) and work well in any use case. In addition, you also need to check the performance of the application under increased load.
This is done by QA engineers, or specialists.
Step 8. Launch and Deployment
Deployment is the last step in the development process. Once the product is ready and passes all tests, it can be registered on such marketplaces as the Google Play Store and Apple App Store. For this you need:
- Register on the Google Play Console and Apple Developer.
- Fill in the appropriate form for adding an application to the listing.
- Pay for registration ($ 25 for Google, $ 99 for Apple) and agree to the user agreement.
After the application gets into the marketplaces, you need to make sure that your product does not lag behind the development of competitors. This will require the maintenance and support of the application, which may include updates to libraries, framework and operating systems, as well as adding new features and making changes to the application based on current business needs.
Step 9. Promotion of the project
For your blockchain application to become popular, you need a marketing strategy that targets your target audience. Here's how much it can cost depending on the promotion channel:
More on the topic of marketing:
- Listings — from 0 to 200 dollars. We already wrote that publishing an app in the Google Play Store and Apple App Store costs money, a similar situation with most other app stores. However, along with this, you can add your software to free app listings, online aggregators, as well as on Instagram, Facebook, Twitter and LinkedIn.
- Paid advertising — from 50 to 5,000 dollars per month. These are pay-per-click or view ads on search engines, social media and websites.
- Content Marketing — from 500 to 10,000 dollars per month. Launching a website with a blog that you will fill with relevant niche content to increase the place in the search results of search engines, as well as increase the awareness and reputation of the company. The content can be educational, informational, news and entertainment articles, videos, photos.
- SMM (social media marketing) — from 500 to 5,000 dollars per month. Creation of posts on Facebook, Instagram, Twitter, LinkedIn and their promotion within the platform, including with the help of influencers.
- E-mail newsletter — from 0 to 1000 dollars per month. Creation of multiple email templates targeting different target audience subgroups. Such letters can contain text, photos, animation, video.
- SEO (Search Engine Optimization) — from 600 to 5000 dollars per month. Analysis of queries in the selected niche, creation of an SEO core, content optimization and link building.
