If you want to learn how to become a blockchain developer, the first thing you need to understand is the basics of blockchain technology. Are you ready? Let's go!
Blockchain Basics
Blockchain is a digital database for storing information. Information is stored in a group called 'blocking'. Blockchain is a bit similar to Excel spreadsheets. However, blockchain has some very special features that make it different. Blockchain is;
Decentralization
Blockchain is not stored in one place - it has no center. It is stored on many different computers. These computers are called nodes. Blockchains are called peer-to-peer networks because no third party like Microsoft, Google, or Facebook is involved. So, no single entity has control over the data on the blockchain, and users interact with each other directly rather than through third parties.
Public
All information on the blockchain is public. This means everyone can see it.
Guided by Consensus
This means that before new information is added to the blockchain, more than half of the nodes must agree that it is valid before being added. This protects blockchain from fraud.
Eternal
This means that after information is added, the information cannot be changed or deleted. Information about blockchain protected by this means that it is encrypted and almost impossible to hack.
The software created is called dApps (a decentralized application). The first DApp is built on the Bitcoin blockchain and peer-to-peer payment system. Other blockchain - like NEO, EOS, and Ethereum - are designed to do more. Blockchains is designed to have all types of dApps built on it. Bitcoin is designed as an alternative to centralized banking. Platforms like NEO and Ethereum want their users to build alternative dApp for all types of centralized applications, such as Twitter, Google, and Uber.
As a blockchain developer, you will help build a fully decentralized internet! That's so cool, isn't that right? All you need to do now is find out how to become a blockchain developer!
The second step in learning how to become a blockchain developer is to determine which blockchain you want to develop. The two most popular development platforms are NEO and Ethereum. Let's see what each platform has to offer its users.
NEO vs Ethereum
Ethereum was created by Vitalik Buterin and aired in 2015. NEO was originally named Antshares and was founded by Da Hongfei and Erik Zhang in 2014. Become a NEO in 2017.
Both platforms allow users to create dApps. They do this in a slightly different way. DApps is made using a programming language, just like ordinary software. NEO dApps can be built with many different programming languages, including C # and Java. This is a popular language that most software developers know how to use it. This makes using NEO easier for experienced users.
Ethereum has its own language called Solidity. This means that even experienced developers need to learn a new language before they can start creating dApps. However, Solidity is similar to other languages like C ++ and Javascript. Most users will find Solidity difficult to get started. However, users who know Javascript or C ++ will find it easier.
NEO focuses on providing a platform for digital business in the future. This follows Chinese business rules and works closely with the Chinese government. Currently the network is faster than Ethereum. This is good for applications that need to process many transactions per second!
