A Comprehensive Guide to Blockchain Mobile App Development

By 2027, the blockchain technology industry is expected to have grown to $4 billion, a compound annual growth rate (CAGR) of almost 56%. These figures reveal a great deal about the future of blockchain applications. But first, can you define blockchain mobile app development? A distributed ledger of transactions, a blockchain is essentially a web of interconnected computer networks. Every block of the blockchain contains a number of transactions. Every time a new transaction is made, a detailed description of it is uploaded to the blockchain of every participant.

Blockchain is a state-of-the-art technology that eliminates the possibility of data theft or hacking. Decentralized application (dApp) development platforms, blockchain app technologies, and blockchain mobile app development are all covered in further detail below.

Blockchain Mobile App Development: Working and Technicalities

A distributed ledger system that uses interconnected “blocks” of public transaction records stored in various databases over a network of “peer-to-peer” nodes is known as blockchain technology. One common name for this form of storage is a “digital ledger.” On the blockchain, every data transaction will be recorded. So, just like a ledger system, the log records each data transaction. Data transfers within the system are called transactions. The ledger system creates a block for the validated transaction.

Blockchain Mobile App Development: Step-by-Step Overview

Before developing blockchain apps or tokens, defining the application’s purpose and scope is important. Anything from a real estate smart contract to a cryptocurrency like Bitcoin could be involved. Therefore, let’s take a look at these steps that can facilitate the development of blockchain mobile apps.

1. Development of Ideas

The first step in implementing blockchain technology is to determine your use case. You must consider the application’s use cases and decide if your idea requires blockchain. Remember that blockchain just works as a means of confirming transactions and encrypting data; it won’t be able to guarantee any further security for transactions if it’s not well-designed.

Blockchain mobile app development is expensive, so keep that in mind after you decide your idea needs blockchain technology. This is because there are multiple approaches to developing a blockchain application, and these approaches vary in terms of cost and usefulness. Take the hypothetical situation of a real estate agent attempting to build a supply chain program using blockchain technology to track every property they sell. Therefore, it is imperative that you are well-versed in the program’s various applications and how they will serve the interests of both your business and the customer.

2. Find the Best Blockchain Platform

Picking the right system or technology to implement blockchain technology is the next step after deciding your firm must do so. You have a choice between two methods.

Create a new blockchain.

The tech stack, algorithms, validation of transactions, and token transaction fee can all be customized in your new blockchain framework. This is the most comprehensive but costly approach to building blockchain apps for mobile devices. Basically, you’re thinking about making your own Bitcoin or Ethereum, which sounds lucrative but can actually cost you hundreds of dollars. This is the default setting; you should only use it when creating your coin.

Clone well-known blockchain platforms

Using an established blockchain platform is preferable to developing one’s own blockchain-based application. You can install these platforms on your servers by forking their code repositories since they are open-source. The most important question is whether the world should adopt your blockchain. Remember that a blockchain platform’s success depends on the number of nodes in the network that can validate transactions. Popular systems include Ethereum, Fabric, and SawTooth, which are all part of the Hyperledger network. Having said that, every single person possesses unique traits that might be useful when making a choice.

Utilize tokens on current blockchain systems.

There is a little difference between this and the previous point. Earlier, we assumed that there would be enough network nodes to “mine” the transactions, so we installed an emulator of the whole blockchain platform on our servers. On the other hand, we may “simply generate tokens” and then store them on a live blockchain, such as Ethereum.

To swiftly incorporate blockchain technology into your application, these platforms offer pre-built APIs, algorithms, and mining processes. Plus, you may keep your tokens and transactions in your wallets since many of them support Ethereum tokens. This is quite similar to the process of creating an online store on Shopify. Stores on Shopify may be quickly and easily set up with just a few pieces of information, thanks to the platform’s pre-built e-commerce features. You can also utilize Solidity to program your own tokens and then use them on Ethereum. Using the platform’s pre-built services, you can use your tokens to make transactions. Tokens can be money, or they can be nothing more than smart contracts.

3. Proto-Development

Blockchain development is expensive, so it’s wise to make a test version of the app to ensure it works before releasing it to the public or integrating it with an existing blockchain platform like Ethereum.

When you’re prototyping your app, choose which parts will be “on-chain” and which parts will be “off-chain. Put simply, if you are building a web or mobile app that uses blockchain technology, then most of its features should be able to function normally, even without a blockchain and on regular cloud hosting. Following this, you will likely deploy the application’s transactional component on a blockchain.

The development of your program, or parts of it, on a permissioned or permissionless network, should also be determined.

Networks that use no authorization. Anyone can sign up and start confirming here. Ethereum and Bitcoin are two of the most well-known examples.

Secure the network with appropriate access. In this case, the network owner decides who can join the network and how many users can check blocks. Both completely new (e.g., authority-based) and identical to permissionless network consensus procedures are possible.

The reason to keep on-chain and off-chain APIs separate is that they will be hosted in different places. The next step is to decide on your application’s consensus technique and transaction strategy. Because many tasks are currently done well on established blockchain platforms, using them will make this step simpler.

4. Technology Used

The blockchain app development process at each stage incorporates several sorts of technologies. Give me a few. These applications make it easier to develop blockchain mobile apps.

  • Ethereum Native Interface (NDI), web3.js (Reference)
  • You can find Trust, Cipher, and Toshi for mobile devices and Mist, Parity, and Metamask for desktop computers among the decentralized application browsers available.
  • Embark is an application framework that uses decentralized platforms such as Ethereum and IPFS to create serverless applications.
  • Among Ethereum frameworks, the truffle is the most popular for testing and development.
  • Metamask enables you to execute Ethereum decentralized applications (dApps) straight in your web browser without the need to host a whole Ethereum node.
  • Parity is the best Ethereum deployment client.
  • The tracking tool, Etherscan, is an Ethereum block explorer.

The aforementioned options aren’t the only ones available for app/server development; other common frameworks include node.js, react.js, and native methods for mobile apps.

5. Development Stage

The last step in developing a blockchain mobile app is the most important. Developing a blockchain application should now be within your capabilities. You must develop or incorporate application programming interfaces (APIs) for certain use cases at this stage. There are a lot of different versions of the application. However, it should be noted that the program’s pre-alpha version has not yet undergone formal testing. After the application is approved, it moves to the alpha stage, where engineers test the program using white-box methods. However, it’s still conceivable that the program is missing some features. Once the alpha version is released, the program is prepared for the beta version. All of its functions are available in the beta version of the software. But maybe there are some bugs that haven’t been found yet.

The developers distribute the beta version to a select group of individuals outside the firm to test its functionality. Following that, the application moves on to the release candidate version. This improved beta version is ready to go live as the final application after testing and acceptance of the beta version. After rigorous testing, the software moves to the production phase, where it is ready to be distributed. Before going live, install the app on the network system and thoroughly test all of its functions. During application deployment, administrators have the ability to manage the distribution of program versions to various resources through provisioning.

Following provisioning, an application must be deployed to the main chain. If your solution combines off-chain and on-chain components, you will need to release your blockchain app to the app store, the Play Store, and the cloud server. After development is complete, the software must undergo regular maintenance to ensure it continues to work with any updates that may be released.

Blockchain Mobile App Development: Platforms for dApp Development

A “decentralized application” (dApp) is an open-source software program that runs on a blockchain network that connects many computers instead of just one. Decentralized applications (dApp Development Services) take after online or mobile app software but include peer-to-peer (P2P) functionality. DApps are compatible with both blockchain and P2P networks. Some examples of applications that facilitate peer-to-peer (P2P) networks include BitTorrent, Tor, and Popcorn Time. These networks allow several users to receive content, feed or seed information, or do both simultaneously.

A few of the most well-known ones for decentralized app development are:

1. The Ethereum

You can build decentralized applications (dApps) on the Ethereum blockchain using the platform’s tools, which include a smart contract paradigm and Solidity, a programming language similar to JavaScript that is aware of dApps.

Regarding decentralized application development, Ethereum is likely the best platform. The Ethereum Virtual Machine (EVM) allows programmers to create smart contracts in the Ethereum language, Solidity.

2. EOS

When it comes to developing decentralized apps, EOS is one of the best blockchain platforms available. Compared to other blockchain platforms, EOS.IO is highly recommended and makes dApp building easy. EOS provides decentralized app developers with a simple mechanism to host applications, execute smart contracts, and use other OS-like features.

Building fully-functional decentralized applications is now possible with EOS. On top of that, it’s a decentralized platform that lets anyone build and run decentralized applications (dApps) on blockchain technology.

3. TRON

Blockchain networks that rely on smart contracts include TRON, Ethereum, and EOS. The decentralized entertainment investment platform that its design is built for sets it apart from other cryptocurrencies. Its purpose-driven development included a blockchain explorer (TRX), its own coin (Tronix), and some novel protocols. The development of decentralized applications (dApps) using TRON Blockchain Explorer is called TRON dApps.

4. NEO

NEO is the best for building digital goods and smart contracts among blockchain platforms. With the help of smart contracts, it plans to grow into a decentralized, distributed network for assets that aren’t digital. Its ultimate goal is to replace analog asset transfers with digital ones.

Several methods and tools for creating decentralized applications (dApps) are pre-installed on the NEO platform. Once you’ve completed developing, testing, and deploying your smart contracts, the next step is constructing decentralized applications (dApps) on the NEO network by integrating them with the blockchain.

5. Cosmos

All of the Cosmos decentralized peer-to-peer network’s separate parallel blockchains use BFT consensus algorithms, such as Tendermint consensus, to reach consensus. This is in reaction to Cosmos, a decentralized network that served as an intermediary between numerous blockchains.

Cosmos SDK, built on top of Tendermint Core, allows programmers to build secure, decentralized apps that use blockchain technology.

Blockchain Mobile App Development: Technology Used

The potential uses of blockchain technology extend far beyond the cryptocurrency market. From the execution of contracts to the efficiency of government operations, technology impacts many businesses in various ways. It has the potential to save time and money for businesses while increasing transparency and fairness. The blockchain makes use of several technologies, so let’s examine them:

1. Solidity

Solidity is undeniably a popular language among blockchain engineers. It drew inspiration from Python, C++, and EVM (Ethereum Virtual Machine) when it was developed. Coded in Solidity, advanced features like inheritance, libraries, and user-defined types are at your fingertips. Furthermore, solidity is the go-to language for building smart contracts, and it supports the OOP paradigm. Solidity allows blockchain developers to build apps with self-enforcing business logic in smart contracts, which can record transactions authoritatively and reliably. Blind bids, multi-signature wallets, crowdsourcing, and voting contracts are all made easier with this.

2. Geth

The Ethereum node implementation called Geth was built using Go. The JSON-RPC server, command line, and interactive console interfaces are all ways to access it. All three of the most common operating systems—Windows, Mac, and Linux—are compatible with Geth, making it ideal for blockchain development.

Token transfers, ether mining, smart contract generation, and exploring block histories are just a few of the many actions performed by Geth on the Ethereum blockchain. You can connect to an existing blockchain or begin building your own after installing Geth. The good news is that Geth simplifies things by instantly joining the Ethereum primary network.

3. Mist

The developers of Ethereum primarily built the Mist wallet. Before you can start using the Ethereum network, you need a safe place to store your Ether tokens and run your smart contracts. It is compatible with both 32-bit and 64-bit versions of Windows, Linux, and Mac.

Even though Mist is wonderful for smart contract implementation, keep in mind that it is a full-node wallet, and you will need to download the entire Ethereum blockchain—which is more than 1 TB—to use it. Another important point to remember is that your Mist password is not something you can change; it is a one-time installation requirement.

4. Solc

Solc is the name of the Solidity command-line compiler that uses C++. Its primary goal is to enhance the Ethereum Virtual Machine’s comprehension of Solidity scripts. Smart contracts built in Solidity, a compressed, weakly typed language with syntax similar to JavaScript, nevertheless need to be converted into a format that the EVM can read and decode rapidly. At this stage, Solc becomes involved.

There are two flavors of Solc: one that is only compatible with C++ and another that is only compatible with JavaScript, called Solc-js. The latter uses Emscripten to cross-compile the former. Most Ethereum nodes already have Solc installed. Offline compilation is another possible use case.

5. Remix

Remix IDE is a blockchain application for creating and implementing smart contracts. Written in JavaScript (so it can be accessed through any modern browser!), Remix is a tool for developing, testing, troubleshooting, and deploying smart contracts built in Solidity. It works fine both locally and in a web browser. With Metamask, Remix makes it easy to connect to the Ethereum blockchain, and the documentation is solid.

6. Metamask

To facilitate communication between the Ethereum blockchain and web browsers like Chrome and Firefox, a wallet named Metamask was developed. Similar to a browser extension, it accomplishes its purpose. If you own Ether or any other ERC-20 asset, you can interact with Ethereum decentralized applications (dApps) and serve them using the Metamask platform. The best part is that it’s browser-based.

Metamask can be integrated with Shapeshift and Coinbase to facilitate the acquisition and exchange of ETH and ERC20 tokens. It is also possible to store keys for ERC20 tokens and Ether. Its compatibility with several Ethereum test networks makes it an ideal wallet for blockchain engineers. Once you’ve installed the browser app, you’ll have access to the built-in Ethereum wallet.

7. Truffle

Truffle, a framework for developing apps on the Ethereum network, is part of the Ethereum blockchain. Its extensive library provides specialized setups for building complex Ethereum decentralized applications (dApps), novel smart contracts, and other challenging blockchain development needs. Automated contract testing is possible with Truffle, thanks to Chai and Mocha. On top of that, it can make smart contract linking, compilation, and deployment easier. Its versatile build pipeline makes it easy to implement one-of-a-kind development procedures.

8. Ganache

Ganache, a part of the Truffle Suite’s Blockchain tool, allows users to create their own Ethereum blockchain, giving them full control over the chain’s behavior as they test decentralized applications (dApps), execute commands, and investigate the state.

The nicest part about Ganache is that it doesn’t charge you for any actions that you would typically do on the main chain. Blockchain engineers find Ganache to be a useful tool for testing smart contracts. Also, it has a built-in block explorer and advanced mining settings; thus, it’s being developed concurrently.

9. Blockchain Testnet

When talking about blockchain development, the blockchain testnet is crucial. Test your decentralized applications (dApps) on a testnet before releasing them to the public. If you want your blockchain solution to work well, though, you need to pick the right testnet. The three main types of blockchain testnets are GanacheCLI, private, and public.

You may test your decentralized applications (dApps) for bugs and flaws on testnets without spending much money or resources. For example, Ethereum runs on gas, which is utilized for various purposes. If you must pay for gas every time you take the car for a test drive, it may get expensive quickly. So, thanks to Testnets, testing is now within reach.

Conclusion

We hope this blockchain app development guide might prove informative. By now, you should have enough background knowledge and examples to begin formulating your own concept for a blockchain app. Are you familiar with this? We are eager to hear your concept and provide our input. When can we meet to talk?
