How To Become A Blockchain Developer - Blockgeeks
In the traditional business model, all the processes are performed manually. Besides, various third parties are involved in every process, which not solely demand an additional amount of money and time, but also charge heavily for their services.
This, altogether, results in a stagnant rise in the cost associated with a particular task. The foremost application of blockchain in the business world is Smart contracts.
As you can depict from its name, Smart contracts are a kind of self-executing contract where all the terms and conditions from both parties are written in the form of codes. These codes are then stored on a decentralized blockchain network, making them immutable. So, whenever the codes written are fulfilled, the associated conditions are executed.
This way, the use of smart contracts encourages businesses to execute legal actions without involving any attorney, government officials, or other fee-charging middlemen to settle down disputes. The collaboration of blockchain and digital payments is also one of the obvious applications of decentralized blockchain networks. By removing the involvement of third parties and associated documents like billing statements and invoices, blockchain has also eased the cash flow in the startups and establishments.
Suppose, you run a medical organization. Wondering how? While being in the same blockchain network, the insurance company will be familiar with the number of times a patient visited your medical organization along with an access to all the payment details. This will create a transparent environment and enable the company to respond to your claim immediately. At the same time, patients also get a comprehensive detail about the co-payment even before leaving your office. It introduces the power of transparency and immutability into the process, making it possible for the companies to combat counterfeiting, delays in product delivery, as well as robust security in the process.
The role of blockchain in the recruitment process of the business world is also becoming more evident. The technology prevents candidates from using photoshop or other such tools to build fake yet impressive documents.
This also aids organizations with saving time required for verifying all the documents and hiring the potential candidate. A consequence of which is that companies are putting their best efforts in connecting with the reputed blockchain development companies and hunting different applications for blockchain in their business.
When focusing on the blockchain impact on business economy , the technology also improves marketing campaigns. Blockchain empowers marketers to keep a real-time track of client information and customer behavior, which helps them to create effective campaigns and derive higher ROI. One of the top ways blockchain can improve your business is by introducing robust security measures in the environment.
The technology comes with the power of decentralization and transparency which encourages users on the network to store and verify some or all of the information stored in the network. This decentralization is what marks the biggest difference between traditional and Blockchain database.
Also, the blockchain network comes with higher complexity and security considerations which lower down the risk of cyber attacks. In addition to this, the concept of blockchain for digital identity facilitates users with the functionality to protect and maintain their identity and see how they can access their information and use it for any purpose.
Last but not least, Blockchain technology also opens new doors for engaging a wider target audience. The integration of blockchain and customer engagement bring forth various opportunities and advantages. Ones which can be achieved by choosing the best Blockchain-as-a-Service provider.
This includes empowering users to take control of their personal information, adds the power of transparency to the business model, foster quick transactions, as well as ensure entrepreneurs and marketers in identifying loyal customers and building trust. While these benefits of blockchain technology for business would have made you inclined towards the idea of investing in blockchain development, it is advisable to determine its future first. When talking about the future of Blockchain technology, it has unparalleled potential to introduce new ideas and concepts into the existence, alongwith integrating to the existing ones and make a great sense of everything prevailing in the market.
That implies that the role of blockchain business applications depends utterly on how much we harness its potential in our business economy. Something related to which various predictions have already been made, including —. A report by Gartner forecasts that blockchain technology will generate an annual business value of around USD 3 Trillion by the year Another prediction by Gartner is that by the end of , the banking sector will attain 1 Bn dollars of business value with the use of blockchain-powered cryptocurrencies.
Blockchain is also emerging as the perfect answer to the fight against Coronavirus by offering real-time tracking information, data immutability, and transparency across distributed decentralized ledgers. When it comes to upgrading your existing business by harnessing the power of blockchain or starting a new startup, it is always recommended to contact the best blockchain development company.
This is so because the technology is still in its novice state and can bring forth various hidden challenges and barriers that could be difficult to tackle without prior experience. Implying, it can be nearly impossible to look into the importance of blockchain in businesses without support of the experts. So, do not overlook this fact. Contact the experts and make the best use of blockchain for business growth. Lab appinventiv Startups How To Guides. Search for:. Do NOT use online wallets to store huge amounts of your money.
Store the bare minimum that you need for exchange purposes. As you create an extensive portfolio, you must learn how to utilize cold wallets to store your money. You can learn how to do so here. As a blockchain developer, you will face tons of challenges in the back-end. Creating and maintaining a public blockchain is not easy because of a number of reasons.
Blockchains, as David Schwartz puts it, should be fortresses. Firstly, the code is public and open for all to see. Anyone can look at the code and check for bugs and vulnerabilities.
However, unlike other open code resources, the downside of finding vulnerabilities on blockchain code is massive. Any programmer can hack in and get away with potentially millions and millions of dollars. Because of these legitimate security concerns, development on the blockchain is usually very slow.
It is important to keep pace with the network. You cannot fall too far behind and not keep up with all the network demands. You should be well equipped to handle remote and local queries. The blockchain must always perform at its highest possible capabilities, but for that to happen the language chosen must be extremely versatile.
All that you need for signature verification is the key, transaction, and signature. With just three data you can conduct verifications in a parallelized manner. However, not all the functions on a blockchain should be done that way.
Think of transaction execution itself. Some languages are good at parallel operations while some are good in non-parallel operations.
That is called deterministic behavior. So, in blockchain development, all transaction operations must be deterministic. You cannot have a transaction that behaves one way and then behaves another way the next day.
Similarly, you cannot have smart contracts that work in two different ways on two different machines. The only solution to this is isolation. Basically, you isolate your smart contracts and transactions from non-deterministic elements. There are some languages that fulfill most of these needs. Javascript is usually used to create highly interactive web pages.
How do we make a block? What does a simple block consist of? Before we continue. You need to understand certain terms that we are going to use in our program:. Ok, so this right here is out a block.
So, in the first line of the code, we called the crypto-js library because the sha hash function is not available in JavaScript. Next, we invoked a constructor inside the class to call for objects which will have certain values.
The thing that probably catches your eye is the calculateHash function. In a block, we take all the contents and hash them to get the hash of that particular block. We are using the JSON. Ok, so we have the block ready and good to go.
So, the moment a new chain is created, the genesis block is invoked immediately. Firstly, we will need to know what the last block in the blockchain currently is. For that we use the getLatestBlock function. So, what is happening here? How are we adding the blocks? How are we checking if the given block is valid or not? So, what we are going to do here is simple. Compare the previous hash value of the new block with the hash value of the latest block. If these two values match, then this means that the new block is legit and it gets added to the blockchain.
Now, we need to check that nobody has been messing with our blockchain and that everything is stable. We created a new cryptocurrency based on the blockchain and named it BlockGeeksCoin. By invoking this new object, I activated the constructor, which in turn created the Genesis block automatically.
Thank you savjee. While it was first proposed by American cryptographer Nick Szabo in , Ethereum is often credited with popularizing the concept and making it mainstream. You can learn more about smart contracts in our in-depth guide here. Anything that runs on a blockchain needs to be immutable and must have the ability to run through multiple nodes without compromising its integrity.
As a result of which, smart contract functionality needs to be three things:. A program is deterministic if it gives the same output to a given input every single time.
So when a program gives the same output to the same set of inputs in different computers, the program is called deterministic. Basically, it states that there is an inability to know whether or not a given program can execute its function in a time limit. This is obviously a problem with smart contracts because, contracts by definition, must be capable of termination within a given time limit. In a blockchain, anyone and everyone can upload a smart contract. However, because of this the contracts may, knowingly and unknowingly contain viruses and bugs.
If the contract is not isolated, this may hamper the whole system. Hence, it is critical for a contract to be kept isolated in a sandbox to save the entire ecosystem from any negative effects.
Now that we have seen these features, it is important to know how they are executed. Usually, smart contracts are run using one of the two systems:. If you are interested in Ethereum development specifically then it is important that you learn solidity as well. We already have a detailed guide to it which you can read here. However, here we are going to give you a basic overview.
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 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. Launching an application on the mainnet takes around months based on the requirements of a client.
