How to Become a Blockchain Developer: a Thorough Guide
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. 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;. Blockchain Basics. Mastering Bitcoin. The Business Blockchain. The Internet of Money. The Book of Satoshi. Attack of the 50 Foot Blockchain.

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.
As an introduction to the Ethereum blockchain, Space Doggos is a well-designed and entertaining platform for any upcoming blockchain developer. CryptoZombies allows users to design a whole army of zombies. To do this, users first have to build a zombie factory.
Then, users can code the way their zombies look and even the way they attack their victims! CryptoZombies is very entertaining and makes a lot of difficult ideas fun. So, if you want to command an army of the undead, then CryptoZombies is the course for you. However, I would recommend Space Doggos.
For this, I would recommend the BitDegree Solidity course. The BitDegree Solidity course is great for users who have learned Solidity basics and are ready to start blockchain programming. The course starts with the environment setup and takes users through to building and launching their cryptocurrency! We've covered the topic quite in-depth, but if you're more of a TL;DR kind of a person, let's see the shorter version of the steps you should take if you want to master blockchain developing:.
