How to Become a Blockchain Developer?
Below is a chart form Ziprecruiter depicting this information:. The chart illustrates the growth in salaries from the start junior developers till the end senior developers of the bar chart. To have a broader view of the salary earned by Blockchain developers, we'll use a different approach and get a breakdown of the average salary earned according to location.
This is typical, as this area is a tech condensed region with high cost of living, and competitive compensation. The Top 6 cities from this list have an average payment than the national average salary; this further broadens our view of just how much these blockchain developers get paid. Please note you do not have to live in any of these cities to get jobs as a blockchain developer. This list is just for a reference purpose to depict how much and well paid these developers are; it is in no way limited only to these locations.
Blockchain is very remote-friendly and a lot of developers work from their homes. This is because companies are not limited to hiring just from their environment.
They can collaborate remotely, enabling them to leverage the global resources of hiring people from anywhere on the planet, as long as they have the skill set they are in search of that would be beneficial to their workforce.
Let me share some insights about this particular listing, and give you some general tips on your job search. Google's Big Query service supports Ethereum smart contract analytics.
This platform allows you to analyze Ethereum transactions; you can look at smart contracts and others. Amazon has their managed Blockchain service on AWS. On June 1st, Amazon announced they are looking for a patent in Blockchain for a supply chain. Facebook also has its libra Blockchain, though they are facing some hurdles with the regulatory bodies, they are working hard to launch their own cryptocurrency. Walmart also has its distributed letter technology, which they are also working on; it's undergoing research with the supply chain.
I have personally been to presentations where Starbucks showed a proof of concept for supply chain solutions within their business. So what are Blockchain's current use cases? While several are experimental, there are many right now with solid consumer demand. The biggest category right now are financial use cases, as blockchain has been most adopted in the financial sector. You can see from the image above that there are about 1 billion dollars locked into defi protocols.
And at its all-time high, it peaked over 1 billion, and it is slowly moving back up. It is an incredibly innovative technology because it provides benefits that cannot be achieved with any other technology. For example, some DeFi apps allow you to earn competitive interest rates on your money, compared to your bank account.
You might be developing an app and want to integrate Blockchain or your boss at work might ask why Blockchain might need to be used in a particular project for the company. Here are some reasons you should use Blockchain. However, if you do not have requirements like this, then I highly recommend sticking with Ethereum for the reasons I provided.
You can also start with Ethereum and change later if you need to. Ultimately you want to learn blockchain fundamentals, and practical hands-on skills at first. If you need to retrain in something else later, you can always do that. You'd have a better start with Ethereum since the developer tools are so popular.
You should avoid starting on a blockchain platform with no support; imagine you google out a problem you can't solve and find no solution to it. Ethereum has a lot of resources and supports growth. I highly recommended Ethereum unless you have a good reason to use otherwise.
Shopify is one of the most widely used e-commerce platforms, which also supports cryptocurrency payments with Coinbase commerce. This allows customers to pay with cryptocurrencies like Bitcoin and Ethereum, instead of using credit cards.
If you were building something like this as a developer, you would need to work with both Bitcoin and Ethereum protocols to integrate payments, instead of PayPal or Stripe 2 common payment processors other developers work with.
Compound Finance is a perfect example of a native blockchain application that provides a benefit that cannot be achieved in the traditional financial system.
For example, it allows you to earn competitive interest rates on your funds compared to your bank account. Since Dai is pegged to the U. This interest is earned based upon utilization of the protocol, as it also supports collateralized lending on the other side of the equation.
As a developer, you might serve several roles in a project like this. Compound is powered by smart contracts on the blockchain, so you would need to master smart contract development with the Solidity programming language to fulfill this role.
To build its modern web interface, a developer needs to be proficient in JavaScript, and a modern front end web framework like React.
This interest rate might be higher than in your bank account. As a developer, you might serve two different roles on a project like this. Distributed ledger technology is going to be one of the biggest transformations of the digital world.

The history of transactions is becoming more transparent with the implementation of blockchain. Since blockchain is a distributed ledger, all members of the network share the same updated ledger. A consensus in the network validates the ledger, which implies that everyone must agree on it.
Changing a single record would result in the modification of all subsequent records. Thus, the data saved on the blockchain is:. If your company manages products which are traded via a complicated supply chain, you would understand how difficult it can be to track an item from its origin.
When the supply of goods from one place to another is recorded on the blockchain, you get a complete audit trail representing where an asset came from and tracks each stop that it covers on the journey. Previous records saved on the blockchain can help to verify the authenticity of products and protect from frauds. You can execute transactions fastly and securely by automating and simplifying business processes with blockchain.
Everyone within the network can access the same information at all times, which results in a quick settlement. Reducing costs is a priority for most businesses. While learning about how blockchain can add value to your business, it is also essential to know about when you should use it.
Following are some of the questions that will help you determine if integrating blockchain into your existing solution is a good idea:. Therefore, blockchain is of no use in that case.
If you have an application that needs to manage massive data, blockchain can be used to manage a single shared distributed ledger. Instead of maintaining multiple databases, blockchain technology will allow you to have a single transparent view of the updated ledger, shared with all network nodes.
Though paper-based documents are difficult to counterfeit, they have limited permanence. If transactions need to be updated and shared frequently, maintaining them on papers can be a time-consuming process. If the data and its history are crucial for your business, you might require a blockchain solution that allows multiple parties to write entries into an incorruptible system.
Does your database need high-performance millisecond transactions? 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:.
Any key can lock, or encrypt, the data. To unlock, or decrypt, we need the other key. The only way to decrypt and make the data readable is by having the corresponding key. In a blockchain system, data is stored in blocks of transactions. The most common definition is as follows:. Now, some of these peers might be evil and intentionally report a tampered version of blockchain data. This means that in order for a blockchain network to be fair and valid, most of the nodes have to be fair.
Since the networks are globally distributed, this is not a possibility. Each block stores a data blob which is usually a list of transactions , its block number, and hash of the previous block:. When creating a new block, the hash of the previous block is calculated and added to the next block. Now if the previous block is altered later in time, the next block will be invalid as the prevHash stored in it will not match the actual hash of previous block.
You have seen how we can store data in a structure called blockchain. In a distributed blockchain network:. This process connects to other process instances running on other machines to receive updates on new blocks, transactions, health and validity checks etc to keep itself updated. At its simplest, Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications or dapps.
Ethereum uses a smart contract on the Ethereum Virtual Machine for different applications to use decentralization and make it useable for mass consumption. Ethereum is a generic platform with a smart contracts engine. So, you can apply it almost anywhere. Hyperledger targets building enterprise blockchain applications with an emphasis on security.
Hyperledger is designed to provide a framework with which enterprises can put together their own, individual blockchain network that can scale and is more secure. This programming language is specifically used to write smart contracts. It is object-oriented, statically typed, and was designed around the ECMAScript syntax to make it more familiar for web developers. Go is ideal for blockchain development, especially for building hyperledger fabric.
The statically-typed yet compiled language has the performance level needed by a blockchain coding language. What makes Python one of the best blockchain coding languages is its open source support. You can find third-party Python plugins and libraries for almost every problem you encounter when developing your blockchain project. The object-oriented feature of this blockchain coding language gives developers the ability to bind the data and the methods together, just like how blockchain binds blocks with chains.
That means you do not need to worry about integration and can concentrate exclusively on the application logic. Learn to code in JavaScript today. It is open source and modular - allowing different modules to be used, plug and play style. This enables a wide variety of enterprise requirements. It is designed to provide speed and scalability that is lacking in public chains due to proof of work requirement, which is essentially nuance mining.
Hyperledger fabric is ideal for building a permissioned, private blockchain business network. By private, it means that it should not be publicly open for everyone to run a peer or transact on the network.
For enterprises, this a big requirement that Hyperledger fabric meets. Enterprises need more control on their data access policies. It will help you create and develop dApps and smart contracts on Ethereum public ledger. You may also want to dive deep into the open-source code of different platforms. Most of them are open-source, and hence the code is readily available for scrutiny or learning. However, creating or maintaining an open-source blockchain is not easy.
It requires you to overcome challenges such as security, performance, resource management, and isolation. There are some languages that fulfill most of these needs in this field.
One of the great things is that blockchain for developers is available with mostly free resources including tutorials, videos, webinars, and training. A smart contract is also one of the vital concepts that you need to learn. 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 use it to automate or add functionality to your dApps. A smart contract needs to have three main features, including:.
Once you feel like you have enough background information and knowledge, you should start looking for a job to apply all your skills and develop new ones. This community is tight-knit, and many of the best developers and thought leaders are constantly engaging with each other to keep up on the latest projects and news.
These meeting places are where a hiring manager will look for new candidates, whether they are online discussion groups or job boards like on Blockgeeks or any other related website in your area, or real-life meeting places, such as conferences. The U. Bureau of Labor Statistics BLS does not collect information on blockchain developers; however, the position would fall under software developers.
However, due to the in-demand nature of the specific skill set, this type of developer may earn more than other programmers. The banking sector, the insurance industry, governments, and retail industries are some of the sectors where these developers can work. Currently, the need outpaces available talent by far. Blockchain technology, artificial intelligence, machine learning, and other emerging technologies are going to lead the world to a new and more productive age; which would be referred to as the fourth largest technological revolution.
This is the reason the demand for software engineers using public ledger skills has increased in recent times. New research has demonstrated that businesses are interested in employing blockchain dev who hold experience in this sector.
According to a LinkedIn article a list of the most in-demand skills for , blockchain is in the top-ten list. It pays very well and is in high demand. It goes without saying, but not every CV can land a job. Nobody will be impressed by a long list of technical skills or experience that has nothing to do with the IT sphere. Such a document can be composed only by professional blockchain and IT resume writers, like the ones working for our company.

When we download a file from the internet it uses the same hash functions to verify its integrity. There are multiple standardized hash function implementations that are used, and most notably SHA You can find libraries that implement SHA hash in all technologies so you never have to write your code for SHA implementation.
It is not a one way like a hash function. That means the data, once encrypted, can be decrypted if you have the required key. You start by generating a special, related pair of keys. These keys can be generated only together as an output of single execution of a key generation algorithm. Any key can lock, or encrypt, the data. To unlock, or decrypt, we need the other key. The only way to decrypt and make the data readable is by having the corresponding key. In a blockchain system, data is stored in blocks of transactions.

By private, it means that it should not be publicly open for everyone to run a peer or transact on the network. For enterprises, this a big requirement that Hyperledger fabric meets.
Enterprises need more control on their data access policies. They also need a permissioned network so they can implement access control as per their own requirements. At a high level, this is how a Hyperledger network works. The permission issuer issues or revokes permissions for all participants and infrastructure components of the network.
Which means there is a trusted certificate authority that issues certificates to all participants. Smart contracts hold logic that defines who can change what on the ledger. And participants write transactions on the ledger by invoking smart contracts.
Here are some other notable projects going on. The Linux Foundation is striving to standardize the process with this project and the opportunities to get involved are both exciting and abundant. Distributed ledger technology is going to be one of the biggest transformations of the digital world.
Business transactions, the internet of things, and our resources could be safer and more secure using blockchain solutions. While there was a lot covered in this post, there is still much more to learn and get your hands on. You will also learn to manage fabric user identities in your application using wallets.

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.
