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.
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.

The IBM Blockchain Platform is a blockchain-as-a-service offering that provides users with deployment flexibility, scalability, and control over network components. The platform uses the Hyperledger Fabric 1. The user interface simplifies and accelerates the process of deploying components of the blockchain network.
This tutorial takes you through the steps for setting up a basic blockchain network with IBM Blockchain Platform. Deploying the Kubernetes cluster should take about 25 — 30 minutes, in addition to the time it takes to set up the IBM Blockchain Platform. If a Kubernetes cluster already exists, then it should take about 60 minutes to complete this tutorial. As a first step in designing any blockchain solution, you need to decide on the blockchain consortium in other words, the blockchain network participants.
If the structure of your blockchain network is similar to that shown in the following diagram, then, as this structure illustrates, you need to create the following:. You should repeat the same steps in accordance with your network structure. Make sure that the Kubernetes service cluster is completely deployed. Select the region, provide the service name and resource group, and then click Create. Provide the name of the existing cluster and click Next. As an entry point to your blockchain, you need to create an MSP organization.
To do this, you need an org admin user identity. The CA creates all of the identities and certificates that belong to your organization in addition to defining the organization. Therefore, as a first step to setting up the blockchain network, you need to create the CA. Start setting your network with the CA.
Click on the CA that you created as shown here:. Click Associate identity. It associates the CA admin identity with the CA node. You can change the identity display name or proceed with the default name provided. Click Register user , and then register an admin for your organization. Set the type for this identity as admin. This identity works as an organization admin and allows you to operate nodes using the console.
The remaining attribute, Maximum enrollments , is optional. Leave it blank and click Next. Next, it asks you to add attributes. This is used for role-based access control over resources. For the purpose of this tutorial, you do not need to use attributes. Click Register user. Repeat Steps 1 — 4 to register one more user with a peer type identity.
This identity allows you to deploy a peer. Admin certificates : Select the enroll ID that you created for your organization as admin identity for example, org1admin. Provide the enroll secret and identity name. Click Generate. It generates the identity as the admin for your organization and adds it to your Wallet.
