Good luck, and have a fruitful adventure! Tags: Blockchain Blockchain development. Ethereum can be either a public or private blockchain type. However, it is without a doubt that the Ethereum main network is a public blockchain. Ethereum is mainly categorized as a public blockchain type.
This is because it is a cryptocurrency that is created with open-source computing codes. The codes can be viewed and used by anyone on the blockchain network. Nonetheless, you can transform your own Ethereum blockchain by designing your own genesis file. You can also set up a unique network id. EOS — This blockchain is quite similar to Ethereum. However, it features more efficient transaction rates that have higher scalability.
The primary objective of EOS blockchain is to enhance industrial-scale applications as a decentralized operating system. EOS is categorized under the private blockchain industry. The complexity of blockchain technology requires you to possess an intensive understanding and applicative knowledge of how common data structures like hash maps, linked lists, graphs, and binary search trees, work.
Advance your skills in cryptography. This is very necessary because cryptography is the driving element of cryptocurrencies. It is in fact the foundation upon which blockchain is built. Familiarize yourself with Dapps. The popular kinds of Dapps that people build on Ethereum are: Decentralized Exchanges Games Gambling Dapps Marketplaces Know how to use the necessary blockchain developer tools.
It is a necessary tool when developing for the Ethereum platform. It also helps to send transactions, interact with smart contracts, and retrieve user amounts. Remix — This is an effective open-source tool that enables developers to write, compile, test, and execute smart contracts.
It is used in the Ethereum blockchain to debug transactions. Truffle — Basically, it makes the work of a developer easier with respect to built-in smart contract compilation, linking, execution, and binary management. Ganache — When you need to test your Solidity contracts, then this is the ideal tool to set up your personal Ethereum blockchain.
It features advanced mining controls and built-in block exploration. Metamask — basically, it is a wallet for your browser. It makes it easy for web applications to interact with the Ethereum blockchain. Learn network-specific languages like Solidity, Chaincode, Viper, etc.
Make sure you develop a decentralized application, i. Register for a professional blockchain certification program Practice strategic skills that will enable you to develop efficient and effective solutions to blockchain-related problems Interoperability is a concept you should learn about Work towards understanding the various blockchain platforms Be versatile and excellent in the different programming languages Learn how various ecosystems or standards operate Study the conditions for front-end and back-end web development Join the network of ICOs and cryptocurrencies in order to have technical knowledge about how blockchain technology operates and also to become a better trader or investor.
This will give you two benefits: Advanced data security and better identity protection The opportunity to contribute to other groundbreaking modern technological fields Lastly, all that is left is for you to start coding! This type of blockchain developer will also be tasked with the responsibility of supervising the whole network and driving advanced decisions associated with blockchain technology. This second type of developer is responsible for the development of smart contracts, interactive front-end designs for decentralized apps, and back-end blockchain.
A blockchain software developer will also supervise the whole stack operating their Dapps. A blockchain software developer employs the structure and mechanisms designed by the core blockchain developer to develop decentralized applications that operate on blockchain networks.
It is necessary for blockchain developers to possess a significant and applicative understanding of the structure and modes of operation of the blockchain.
In-depth knowledge of data structures A prospect in the field of blockchain development should understand the basics of data structures, as well as how to apply this knowledge. Without the knowledge of different data structures, a blockchain developer will be unable to utilize advanced cryptography to design a secure and immutable blockchain. Smart Contract Development The launching of Ethereum has greatly popularized the concept of smart contracts. Learning about smart contract development involves knowing network-specific languages such as Chaincode, Viper, and of course Solidity.
Basic Understanding of Cryptography The functionality of cryptographic methods in the development of blockchain cannot be ignored. Without a basic understanding of how these cryptographic methods are employed in blockchain development, it is impossible to venture into the blockchain technology industry. Web-Development Skills This is one of the blockchain developer skills that are useful for the basic designing of decentralized applications. Possessing web-development skills will imply that you have the basic knowledge of both front-end and back-end development skills such as API handling, development of interactive graphical user interfaces for Dapps, and request handling amongst others.
Knowing how to code Coding is definitely a necessary skill that can not be compromised when it comes to blockchain development. Every blockchain engineer is required to know the basics of coding and how to effectively and efficiently write codes within the blockchain system.
Versatility with Different Programming Languages As it has been mentioned a couple of times in this article, different blockchain platforms may have their network-specific languages. In order to maintain your relevance as a professional blockchain developer, you have to familiarize yourself with the various programming languages that you can learn. Platforms and Networks There are several blockchain platforms and networks actively operating in the blockchain system.
A prospective blockchain developer should be able to understand how each of these blockchain networks and platforms differs from each other.
Knowing their unique features is necessary. Challenges Faced by A Blockchain Developer The blockchain technology has its challenges and below are some of the issues that blockchain developers may be faced with:. The code in blockchain systems is public and visible for everyone.
This means that hackers can take advantage of this to hack the system and paralyze the security of blockchain transactions. By implication, this delays the development of blockchain. Management of Resources Another challenge blockchain developers face is that they constantly have to meet up with the demands of all remote and local users with the real-time response the moment they go live. Coding Language It is necessary for the coding language to be versatile.
This is because certain codes can be executed parallel, while others can not. The differences in programming languages when it comes to parallel processing is a challenge that blockchain developers are trying to resolve. Separation It is expected that every transaction in every situation should have the same outcome. In the same manner, smart contracts should also be deterministic.
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;. 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. 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:.
