Contents 1 Skills and knowledge 2 Where to find relevant resources for learning 3 How to get make money as a blockchain developer 4 Other important things needed to become a successful blockchain developer. To ease things up for you, we have written this guide to help you learn blockchain development and give you action steps at the end of each section.
The scope of development on the Bitcoin blockchain was a little limited. Developers all around the world finally had the opportunity to build applications on top of a blockchain. This is the reason why learning blockchain development has become such a hot skill.
The impact that it can have on our future is truly scary and magnanimous. If you are to become a blockchain developer, then there are certain steps that you need to take.
Hopefully, at the end of the guide, you will have the tools required to kick-start your journey. If you are serious about becoming a developer then we need to set some expectations for you.
Firstly, it is going to take time and you will need to dedicate your time and resources to your education you can continue your blockchain development course by taking our online classes. Secondly, do not expect immediate results, becoming a blockchain developer is not a magic pill. One of the biggest hurdles with anything as new and revolutionary, such as the blockchain technology, is familiarizing oneself with various concepts integral to the system.
If you are a beginner, then there are certain terms that you need to be familiar with:. It could be advisable to learn more about these terms that are widely used in the crypto-sphere. It is highly recommended that you go through our comprehensive glossary.
It is important to learn these basic terms otherwise you will be very lost further on in your education. Now, up next, it is time to educate yourself some more on the technical aspects of the blockchain. If you are interested in the technical aspects of how to create a fin-tech application on top of the Blockchain then you should definitely learn the ins and outs of crypto-economics.
This difference in knowledge is extremely apparent when you study some of these ICOs floating around. So, in light of that, it can be a good idea to read up a bit on economics and have a general idea of it. If you want to learn about crypto-economics in general, then you may check out our article here.
If you are intrigued by the cryptography specifically and want to know how signatures work and what public-key cryptography means, then read this. After that, it is highly recommended that you understand how bitcoin works. You can even call it the finest example of what the blockchain technology can achieve purely because of the impact that it has had. You can find it over here. Now that completes the first milestone. How can you possibly innovate and improve upon a platform when you have not used it even once?
Go to Coinbase or any other exchange that you are comfortable with or is accessible in your country and buy some coins. It is extremely straightforward. Since you are not going to be buying a lot of coins then simply use a basic online wallet. These wallets are the easiest to use among all.
Furthermore, you can access this wallet from any server or any device in the world as long as it is connected to the net. Having said that, there is one big problem when it comes to online wallets. Your private key is going to be saved on another server. This is basically like serving up your key to hackers on a silver platter. 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.
What it takes to become a blockchain developer
What makes Bitcoin so exciting is that it uses consensus in a truly massive peer to peer network to verify developer transactions.
