A Beginner’s Guide to Blockchain Programming
Space Doggos allows beginners to learn blockchain development by creating characters and environments for an adventure in space. I will explain this more in blockchain next section! Call them sub-divisions of Blockchain development. Rating 5. CryptoZombies is very entertaining and makes learn lot of difficult ideas where. Check out Simplilearn and get started on development new, rewarding, and profitable career!
You will surely come across many new concepts, terms, programming languages, and developer tools. It can feel like you are stepping into a different world entirely. In many ways, you are! There is a reason that the blockchain revolution is often referred to as the arrival of Web 3. While some aspects of Web 2. There is a steep learning curve to overcome in order to understand the blockchain, and how to build applications for it.
How can you overcome this learning curve faster? How can you make learning blockchain programming easier? The best way to learn blockchain programming is to find a simple programming tasks that introduce you to the new way of doing things and force you to learn all of the concepts that enable you to perform the tasks and explain why the tasks work.
Much of this supporting knowledge you gain this way is conceptual knowledge. This task-oriented approach starts with identifying a question that you want to know the answer to, then identifying the task that will give you the answer.
You break this task down into skills, and then acquire the supporting knowledge that will enable you to perform these skills. These steps look like this:. What task will answer this question for you? The answer is to build a blockchain application! You then must identify the skills in order to complete this task, like learning a new programming language.
You also must identify all supporting knowledge like what is happening when the code is executed. All of this supporting knowledge will teach you something about how the blockchain works and how the application works.
When applying this method, big tasks must be broken down into smaller subtasks. For example, building a blockchain application is to big of a task because it produces an overwhelming number of skills that you must learn in order to complete it!
The best way of applying this method is to find small tasks that support a larger purpose and accomplish bigger tasks. It must be treated like an iterative process. If the task is too big, it must be broken down into subtasks, and you can perform the task-oriented learning process on each subtask. I admit, this can be very hard.
I can identify with this, as I learned blockchain programming on my own without many good resources available. I had to identify all of the questions, tasks, skills, and supporting knowledge myself! But because of this, I can accelerate your learning by pointing you to the tasks that will give you the most understanding, break them down into the skills you need complete the tasks, and all the supporting knowledge that will enable you to complete that will give you the most understanding!
I can maximize efficiency by showing you the simplest subtasks that yield the most benefit of knowledge. This can be broken down into smaller subtasks. The subtask that I want to focus on in this article is — sending ether from one account to another —.
This is one of the most basic subtasks in developing decentralized applications on the Ethereum blockchain. It will teach you a lot about how the blockchain works, while simultaneously teaching you how to complete a fundamental programming task that you can build upon to accomplish more complex programming tasks. Now that we have the task, to send Ether from one account to another. Here is what the code looks like to complete this task:.
In order to complete this task, you simply need to execute this code in a JavaScript runtime environment that connects to an Ethereum client through Web3JS. Some of these things might be obvious, but continue reading as you will learn something new as the explanation unfolds! As I mentioned previously, this code is written in JavaScript and can be executed in a JavaScript runtime environment with the Web3.
It allows you to read and write data, as well as execute code on the Ethereum blockchain. Understanding how Web3. This node acts on behalf of the entire network! A diagram of that relationship looks like this:. See, Ethereum is a peer-to-peer network where each node shares responsibility of maintaining the network.
JavaScript is one of the go-to languages when making a simple but tamperproof blockchain that is impossible for hackers and other deceitful individuals to alter. Just one setback, though: The language lacks the SHA hash function. The language is not only beginner-friendly but also offers tips and instructions on how to go about using its code. While the language is not very complicated, those who have a fair grasp of modern programming languages have an advantage.
Even though Solidity is still trying to establish its footing in the coding world, Ethereum the second-biggest cryptocurrency after bitcoin is already using it. Well, they made the language, so it makes sense that they be the first ones to use it. Nevertheless, Ethereum blockchain is one of the most efficient when it comes to speed and ease of creating smart contracts. So if you are looking to create a decentralized app, hold an initial coin offering, or build a secure, immutable, and multipurpose blockchain, Solidity is the language to use.
It's a must-know language for anyone who wishes to integrate smart contracts in their digital ledger. GO is the short form of GOLang, a relatively modern coding language that was developed in at Google and officially released for public use in GO inherently runs in an operating system, and this means maximum flexibility, especially when dealing with several parts of a blockchain simultaneously.
Although blockchain represents only a single item, there are different parts in it that developers can work on. The core parts of a blockchain you can develop include:.
The most skilled programmers usually browse through a storm of resources on anything before getting started. If you want to immerse yourself deeper into the blockchain world, then you need to buy some cryptocurrencies just a few and play around with them to see how the platform works. There are many entertaining yet in-depth courses out there that will teach you blockchain programming step by step. Space Doggos and CryptoZombies are some of the gamified courses that turn work into play so beginners can have an easier time coding.
Space Doggos is a space adventure game that teaches learners how to develop the Ethereum blockchain. The game is detailed with several chapters and notes for gamers. The concept is almost the same with CryptoZombies. Take a look at the next section for places where you can learn to code a blockchain in detail.
These tutorials only help to clear the foggy coding path. You need advanced courses in whichever language you prefer to create a useful, secure, and faster blockchain. Developing a blockchain comes with a lot of challenges. Therefore, as a budding developer, you need to constantly mix with individuals of the same passion on platforms like GitHub, Reddit, Stack Exchange, and many others. Chat with participants, ask questions, and seek assistance from the mature members of the community in order to build a project with little to no errors.
Blockchain and cryptocurrencies, particularly bitcoin, are believed to have a huge role to play in asset and data transfer. These blockchains are designed to have all kinds of dApps built on them. Bitcoin was designed as an alternative to centralized banking. So, it's highly beneficial to learn how to become a blockchain developer if you want to create something equally as great.
The second step is deciding which blockchain you want to develop on. Two of the most popular development platforms are NEO and Ethereum. Looking for more in-depth information on related topics? We have gathered similar articles for you to spare your time. Take a look! Gain skills for life and business with these top 7 options of psychology courses free and paid options included.
Looking for an introduction to programming using Python? Let's see what the best course is! Level up your business skills and beat the competition with these best online business courses. Ethereum was created by Vitalik Buterin and went live in It became NEO in Both platforms allow users to build dApps. They do this in slightly different ways. DApps are built using programming languages , just like regular software. These are popular languages that most software developers know how to use.
This makes using NEO easier for experienced users. Ethereum has its language called Solidity. This means that even experienced developer needs to learn a new language to be a blockchain developer and start building dApps. Don't let that deter you from learning how to become a blockchain developer though. NEO is focused on providing platforms for the digital businesses of the future.
It follows Chinese business regulations and works closely with the Chinese government. It is also currently a faster network than Ethereum. This is great for applications that will need to process a lot of transactions per second! Ethereum also has links with big businesses like Mastercard and Samsung. However, Ethereum is more focused on encouraging users to develop the blockchain than NEO is.
It also has the largest dApp building community of any other blockchain. This is why I believe Ethereum is the best platform for a newbie to start their development training. Solidity was developed by an Ethereum team , which was led by Dr.
Gavin Wood in Solidity is used to write smart contracts. Smart contracts are used to create dApps. It's vital to understand smart contracts if you're curious about how to become a blockchain developer.
Smart contracts are the rules which guide transactions on Ethereum's blockchain. If the conditions of a smart contract are met, the transaction will happen.
If the conditions of a smart contract are not met, then the transaction will not happen. The transaction is between Diana and Ross;. Diana is selling a football online for 5 Bitcoins BTC. Diana receives 5 BTC from Ross and sends him a football. The way that Bitcoin blockchain developers programmed it, the transaction looks like this:. What Diana and Ross need is a smart contract.
Diana is selling football for 70 ETH. Ross wants a football so he sends Diana 70 ETH. Both parts of the contract have to happen for the transaction to be completed. Which transaction would you prefer? They can be used for lots of different things. Solidity smart contracts can be used to guide all kinds of transactions from secure voting in elections to rental agreements.
Solidity is a high-level coding language. This means that it is designed to be read and used by human beings! Computer programs are usually written in a high-level language and then translated into a low-level coding language.
Now, if you really want to know how to become a blockchain developer, you must learn about low-level coding languages also. A low-level coding language is designed to be read and used by computers. Low-level languages are made up of 1s and 0s. This is called binary. When a blockchain developer builds dApps and smart contracts on the Ethereum blockchain, there are rules which guide their design. For example, if you want to design a new cryptocurrency using Solidity you have to follow a set of rules called ERC These rules make it easier to tell how new dApps will work when they are launched on the blockchain.
Ethereum blockchain development happens in a very special place called the Ethereum Virtual Machine. A virtual machine is an environment where new computer programs can be written. You would build and test your car in a factory and on empty streets.
This is how the EVM works. It is a factory for building new smart contracts. This makes Ethereum a great place to learn blockchain. The EVM allows users to practice blockchain programming without worrying about making mistakes. The EVM is also Turing complete. This means that whatever a computer can do, you can design using the EVM. The only limit is your imagination! Think of all the exciting new ideas being built using the EVM right now! Learning Solidity is a lot like learning to speak a new language , but it is essential to become a blockchain developer on the Ethereum platform.

Get started with blockchain development Learning Path 6 Modules. In this learning path, you will: Learn the foundations of blockchain and how blockchain technology works. Gain an understanding of the tools to develop on the Ethereum blockchain.
Most subreddits though are primarily dominated by speculators, and are not a good use of your attention. Stay away from Bitcoin-related subreddits.
Bitcoin notoriously has one of the most toxic communities, and Reddit only magnifies that. Twitter is more of a mixed bag. For better or for worse, most blockchain people live on Twitter. Blockchain Twitter was somewhat of a mystery to me at first, but eventually I developed an informal ontology of Twitter blockchain people.
Entrepreneurs can be okay, though they mostly act as hype men or tweet about their own projects. Pay the most attention to the builders. A few representatives from each category do a breadth-first search of who these people follow if you want to fill out your Twitter feed :. All that said, I recommend minimizing your exposure to Twitter and Reddit.
Important information will bubble up to you asynchronously. I recommend subscribing to Inside Bitcoin for daily digests of the most important crypto news pieces it covers more than just Bitcoin. For token projects, Token Economy has excellent weekly writeups, and Week in Ethereum has good digests of developer-focused happenings in the Ethereum ecosystem.
Focus on building stuff and learning. Long-form content tends to be the best bang for the buck. I recommend following these:. If you want a more structured approach to learning this material, there are a few high-quality books and courses out there and a lot of low-quality ones.
The best overall textbook for blockchains is Bitcoin and Cryptocurrency Technologies which accompanies the Princeton Coursera course.
If you want a more structured approach to learning this material, there are a few high-quality courses out there and a lot of low-quality ones. As I said before, blockchain startups are hiring like crazy. AngelList did a great writeup on how to get a job in the crypto space. The job aggregators are more global though.
Most blockchain teams are willing to hire remote for the right talent. Many devs are readily accessible on Twitter, Github, or on their public Slack channels. If you have a solid portfolio and can demonstrate technical chops, most people will be impressed if you show some initiative. Cryptocurrencies are still in their infancy, and I really believe the is the most rapidly evolving space you can be working in.

Prerequisites The theoretical foundations of Bitcoin Building a blockchain yourself Ethereum and smart contract programming Smart contract security Taking off the training wheels Building your own projects Navigating the blockchain community Getting a job Why should you learn blockchain development?
Much of the innovation is happening outside of academia. The demand for talent far, far exceeds supply. Cryptocurrencies are just really damn cool. So say you want to throw in your hat. What do you need to know before you get into the ring?
Here are some good prerequisites to be familiar with, in order of importance. Cryptography Cryptography is the namesake and bedrock of cryptocurrencies. Networking The decentralization of blockchains derives in large part from their peer-to-peer network topology. Economics Cryptocurrencies are inherently multidisciplinary — this is part of what makes them so fascinating and radical. Game theory The most important branch of economics that plays into cryptocurrencies is game theory , the study of payoffs and incentives among multiple agents.
Macroeconomics Cryptocurrencies are not just protocols, they are also forms of money. Microeconomics Cryptocurrencies are also deeply interwoven with markets, which requires an understanding of microeconomics. The Theoretical Foundations of Bitcoin In October of , Satoshi Nakamoto published a white paper in which he described a protocol for a decentralized digital currency.
Start here: I recommend watching more than one video explanation to get the idea seared into your head: Great. You should have an idea of why Bitcoin folks argue so much about the block size. Segregated witness, a. SegWit , not essential but it comes up a lot. Lightning Network , one of the more important scaling solutions for Bitcoin, also generalizes to other blockchains Bitcoin full nodes , Bitcoin fee statistics , charts , charts and more charts Bitcoin energy consumption index at the time of publication, Bitcoin mining consumes as much energy as all of Peru Insightful essay by Gwern on the scrappy inelegance of Bitcoin Jameson Lopp has a wealth of other resources on Bitcoin if you want to go deeper down the rabbit hole.
First, a more detailed high-level explanation of Ethereum: The ideas behind Ethereum have also spawned a wave of innovation in cryptoeconomics. Smart contract security Security is absolutely essential to blockchain development. Navigating the blockchain community The best way to really understand the blockchain world is to immerse yourself in it.
Media The three fantastic podcasts I recommend are the Software Engineering Daily Blockchain interviews , which provide good technical intros to many topics and cryptocurrencies. Online reading For realtime blockchain chatter, it lives mostly in two places: Reddit, and Twitter.
Books and courses If you want a more structured approach to learning this material, there are a few high-quality books and courses out there and a lot of low-quality ones. Getting a job As I said before, blockchain startups are hiring like crazy.

How To Become a Blockchain Developer: A Step-by-Step Guide
TED Talks speaker Bettina Warburg connects the dots between the business, economics, and technology of the blockchain. Trying to learn blockchain programming can feel very overwhelming! You will surely come across many new concepts, terms, programming languages, development developer tools. Note: A keyword is learn way a coding tool is written in Solidity. We've covered the topic quite in-depth, where to learn blockchain development, where if you're more of a TL;DR kind of a person, blockchain see the shorter version of the steps you should take if you want to master blockchain developing:.
The Best Programming Languages for Blockchain
If the conditions of a smart contract are not met, then the transaction will not happen. The transaction is between Diana and Ross;. Diana is selling a football online for 5 Bitcoins BTC.

Learning Solidity is a lot like learning to speak a new language , but it is essential to become a blockchain developer on the Ethereum platform.
Solidity basics are like nouns, adjectives, and verbs. Nouns, adjectives, and verbs are tools for creating sentences. Here are some of the tools for creating Solidity smart contracts;.
Variables - These are used to store information on the blockchain. There are lots of different kinds of variables but here are some of the most common:. Booleans - These are used to store information that is either true or false. The keyword for Booleans is bool. Integers - These are used to store information as a number. There are two types of the integer. Regular integers can be positive or negative numbers. Their keyword is int. Unsigned integers can only be positive numbers.
Their keyword is uint. Addresses - These are used to store Ethereum addresses. Each Ethereum user has its address or addresses on the blockchain.
Diana and Ross, from the example earlier, would both need addresses for their smart contract to work. Strings - These are used to store text information. Their keyword is strings. Functions - A function is used to do a certain job.
A function can use information from variables to create new information. For this sum, the keyword would be function add. This is what sums look like in smart contracts;. Structs - These are used to put variables into groups. Do you remember that new car you were building? In Solidity, you could use a struct to group information about your car! It would look something like this:. Not only are there basic courses, but also game-courses that could teach you!
Two courses that teach you how to become a blockchain developer are Space Doggos and CryptoZombies. Space Doggos and CryptoZombies are both gamified Solidity lessons for beginners.
This means that they both turn Ethereum blockchain into a game! Space Doggos allows beginners to learn blockchain development by creating characters and environments for an adventure in space. The first lesson contains ten chapters of information and tasks to get you started. Each chapter has detailed notes on the processes being used.
These include the variables, functions, and structs I talked about earlier. Users can design their astronaut dog using real Solidity code. The code becomes more complicated as the adventure continues.
