Bitcoin is only one of hundreds of cryptocurrenciesand cryptocurrencies constitute just one of hundreds of applications of the Blockchain technology.
For over 30 years of its existence, the Internet has completely changed our world. Blockchain does it even faster. And the social changes it generates, will be even deeper. Like the Internet revolution brought about losers and winners, companies that achieved a huge success and companies that are already forgotten, even greater reshuffling in the market will take place in dozen years.
And this will affect every sector which takes advantage of the benefits provided by the Internet and processes greater quantities of data. The race, that the majority neither notices nor is aware of, has already started. The Blockchain technology is implemented much faster than the Internet had been disseminated in business and everyday life.
The potential of Blockchain is perceived not only by young visionaries focused on start-ups. Big players and the largest corporations are moving towards this technology. In , TUI, one of leaders in the tourism sector, moved all its booking operations to a private Blockchain and, thanks to that, achieved better automation and allocation of sale of hotel accommodation in its whole distribution network. As a result, costs were reduced and operation speed and global data availability were improved both for TUI system operators, as well as third-party partners.
It provides users with initially set structures of Blockchain that operate two versions of this technology: Ethereum and Hyperledger Fabric Linux Foundation. Thanks to that, programmers avoid time-consuming manual configuration of their network while developing their own programmes based on the Blockchain technology.
IBM made an offer to Canadian authorities of the British Columbia province to use Blockchain technology solutions to control and supervise legal marihuana production and trade. The authorities of Seoul want to implement this technology to manage public transport and safety in the city, as well as to collect all lawfully required information about residents by If yes, you should stick to the centralized system for managing the records.
On the other hand, even though blockchain databases are slow, they are far more secure than the centralized system. There could be many reasons why a third party should handle some authorizations and authentications, as it can sometimes be desirable. But, third-party authorities can always create trust issues due to a lack of transparency.
On the other hand, multiple parties manage blockchain data, and information is validated via an agreed-upon consensus algorithm. If you have privacy concerns, it can become possible to provide read-only and write-only permissions to a specific party using blockchain.
No dependency on a central authority will reduce:. Trusting other parties is essential when doing business, especially in a partnership situation. We have to trust banks to keep our money secure and business associates to maintain agreements. What if the trust gets broken?
Now, the question is, how would you know when to use blockchain. Though blockchain is a trustless environment, parties can work simultaneously without worrying as they have an updated ledger at all times.
It uses various consensus algorithms to validate all transactions without giving more attention to any particular party. Hence, it brings fairness to the system. Everyone considers blockchain as an immutable system as it does not allow you to change rules on the system once they are written. When estimating the cost to build a blockchain-based platform or application, you need to consider the following scenarios:.
Here is our analysis of the estimated cost of blockchain development for a minimum viable product when using different development resources.
Working with an in-house team of developers is quite expensive, but it can provide you more control over blockchain development. However, you should take this path if software development is your core business. On the other hand, hiring freelance blockchain developers could be less expensive but very risky. Working with a third-party company could be a viable option if your project is enormous. Blockchain companies are experienced and can help you at every step of the development process.
When compared to an in-house development team, the cost of blockchain companies is lower. Every business requires a digital solution to run their business operations efficiently. Building a blockchain app can build trust and offer transparency while removing additional intermediaries. Before implementing blockchain technology and estimating its cost, it is essential to understand the type of blockchain app you need.
Whether you need a permissioned blockchain app or a permissionless blockchain app, you need to consider which application can suit your business needs. Also, the cost of a blockchain application varies from industry to industry. For example, you may need an app for supply chain management, healthcare, real estate, education, and many other business domains. The cost of an app will depend on the complexity of the project. The cost of blockchain app development also depends on the number of resources required to develop an application.
Salaries of blockchain experts are the significant expenses you should not miss when calculating the cost to build an app. While investing in blockchain developers, ensure you have hired the best ones and added their salaries to the total expense. Companies might use agile methodology tools such as Jira, Confluence, and Trello to manage blockchain projects.
They use such tools to test an app, track timelines, and deliverables. Therefore, the price of project management tools is also added to the cost of blockchain implementation. Your blockchain app might require a subscription to third-party subscription tools such as bug tracking tools, notification services, amazon web services, software monitoring services, and data analytics tools. The cost of subscription tools also contributes to the cost of blockchain app development.
In this section, we have explained the process of building a blockchain-based application. First of all, it is essential to develop a problem statement and understand all of the issues you want to solve with a proposed solution. Ensure that the blockchain solution will benefit your business abilities. Analyze whether you need to migrate your current solution to the blockchain, or you require a new application to be developed from scratch.
For example, suppose you are a healthcare provider who wants to develop a blockchain-based health record exchange app. In that case, you should know various use cases of the applications and what benefits it will offer to users.
Once you decide that you need a blockchain solution for your business operations, the next step is to select the right blockchain platform and blockchain development tools for your project. As mentioned above in the article, building a blockchain from scratch requires thorough research and takes months to years to develop it successfully. Therefore, you should build a blockchain app on top of a blockchain platform that meets your business requirements.
You should identify the right blockchain platform for your application based on the factors like consensus mechanism and problems you want to solve. For example, you can build an Ethereum-based application to develop a decentralized public application with smart contracts. When the blockchain platform is identified, you must do brainstorming and understand the exact business needs.
Once you identify the blockchain platform for developing a blockchain application, you should focus on drafting business requirements and brainstorming ideas.
Find what technology components should be added as off-chain or on-chain entities on the blockchain ecosystem. Create a roadmap of the product that will help you to build an application within a decided deadline.
You should come up with a blockchain model and conceptual workflow of the blockchain application. Also, decide if the application needs to be developed on a permissioned or permissionless blockchain network. It would help if you also decided on front-end programming languages to be used, servers, and external databases in this stage.
A proof of concept is done to represent the practical applicability of a blockchain project. It can be either a design prototype or a theoretical build-up.
In Theoretical Build-up, each project requires theoretical cases so that users could understand the applicability and viability of the product. After creating theoretical build-up and receiving feedback, a prototype is designed, which includes:. When the client approves the PoC, the next step is to prepare technical and visual designs for the application.
Since you have planned an entire application at this stage, start creating UIs for each software component. Designs APIs that will be integrated with user interfaces to run an application at the back-end. Once the admin consoles and user interfaces are designed, the application gets ready for development.
Development is the significant phase of the blockchain development process, where you should be ready to build the blockchain app. In this specific stage, you either have to develop or integrate APIs for particular use cases of the application.
The application is built under multiple versions. Once the client approves it, the application moves to the next stage, i. But, the software might not comprise all the features at this stage. After the alpha version is released, the app is prepared for the beta version. During Beta Phase, the software application has the complete feature set but with some unknown bugs. Developers share the beta version with a particular group of people outside the organization to test its functionality.
Once the beta version is approved and tested, the application moves to the Release Candidate version, which is an advanced beta version that is ready to be a final application and can be launched. After thorough testing, the application moves to the production phase and gets ready for delivery. Before an app goes live, you should deploy it on the test network to carefully test its functionalities.
When deploying an application, administrators can also manage which versions of the app need to be deployed to various resources with provisioning. Once an application is provisioned, it needs to be hosted on the main chain. If your blockchain app is a hybrid solution, i.
The application should be able to upgrade according to any new business needs and prioritization. For instance, if you need to upgrade the smart contract, later on, you should be able to deploy the new contracts without any difficulty.
Developing and deploying an app does not mean you are done. Instead, a software application needs to be maintained post-development to ensure that it works with all types of upgrades in the future.
An Ethereum client, Geth, is used to run Ethereum nodes in the Go programming language. Using Geth, users can mine Ethers, create smart contracts and run them on EVM, explore the block history and send tokens between addresses. Geth can be downloaded and installed on Linux, Windows and Mac.
It supports two types of installations, Scripted and Binary. Once you start using the Geth, you either have an option to create your own blockchain based on the provided settings or connect to the existing blockchain. Remix IDE is a compiler used for small contracts. It is a browser-based tool used to create and deploy smart contracts. You can use Remix IDE to write, debug, test and deploy smart contracts using the Solidity programming language.
Remix can connect to the Ethereum blockchain via Metamask. Before using Ethereum, you should have a place to store Ether tokens and execute smart contracts. Mist is the Ethereum wallet used for smart contract deployment and is available for Mac, Windows and Linux. While installing Mist, remember once you set up the password, you cannot update it again. Create a strong password and never forget it. It allows users to make calls to the blockchain without the need to run an Ethereum node. GanacheCLI is used for the instant mining of transactions.
It is an easy-to-use API that provides you with an overview of test chain events. Security plays a prominent role when it comes to building a blockchain application.
You need to ensure that the Solidity code does not have security holes. Solium tool is specifically designed to format solidity code and fix security issues in the code. EtherScripter has an easy-to-use interface used for coding basic smart contracts. With a simple drag and drop interface, developers can connect different components as jigsaw puzzle pieces for developing a contract.
It only supports the Serpent programming language. A development framework for Ethereum-based dApps, Embark, is used to build and deploy dApps and enable you to create smart contracts written in Javascript programming language. If an application contains multiple contracts, Embark can also handle the migration of smart contracts.
Developers can manage contracts on multiple blockchains such as live network, testnet and private net using the Embark framework. It is a wallet that connects Chrome or Firefox with Ethereum blockchain by acting as a browser extension. It can save keys for Ether and ERC20 tokens. It can be installed simply as a Chrome extension. Since blockchain is immutable and transactions once added to it cannot be updated or removed, untested programs can result in high costs. That is why it is essential to test a decentralized application before it is deployed on the mainnet.
Ensure to test your app on Blockchain Testnet before going live. Truffle is a framework for Ethereum that provides a development environment. The framework supports a library which can link complex Ethereum apps and offer custom deployments to make contracts coding simpler. It supports some of the features mentioned below:.
You will find numerous tools that can be used to develop blockchain apps dApps and smart contracts. To know which is the best blockchain development tool for your project, consult our team of blockchain experts.
The project is initiated with PoC, which typically takes weeks. Once the PoC is done, it takes weeks to develop a minimum viable product with bare minimum features.
