If you’re interested in learning about blockchain, there are a number of online courses you can enroll in. They can provide you with a thorough understanding of the technology and help you take your career to the next level.
These blockchain courses online available at different levels, from beginner to advanced. They’re all self-paced, so you can learn on your own schedule.
1. Introduction to Blockchain
A blockchain is a distributed, encrypted database that stores data chronologically. Each block in the chain contains a hash of the previous block. This makes it impossible for anyone to change a block unless they know the hash of every block that came before it.
Blockchain is being used by a variety of companies, including PayPal and Amazon. It is also being used for a wide range of different projects. The technology has been used in the banking and finance industries as well.
The best thing about a blockchain is that it has the ability to store information in a secure way, and it’s also completely transparent and unchangeable. This means that it’s perfect for businesses and other organizations looking to improve their client and customer engagement.
If you’re interested in learning more about blockchain, there are several online courses available to help you get started. These courses will give you an overview of how this technology works, as well as how to use it in various applications.

2. Ethereum
Ethereum is an open-source blockchain platform that allows users to create distributed applications that run on the network. It also allows users to control their data without a central server.
Essentially, the Ethereum platform works like an escrow account, where each user has a cryptographic private key and a corresponding address that they can send money to. In this way, if Alice wants to send 1,000 ETH to Bob, she doesn’t have control over that money until Bob uses his corresponding address to transfer the ETH into his own account.
This blockchain course will teach you how to build your own blockchains from scratch using the Ethereum platform. It is one of the most comprehensive courses available online, and it can help you get a head start on a career as a blockchain developer.
It is an ideal choice for those who have a basic understanding of programming languages and are interested in learning about Ethereum blockchain development. Upon completion, you’ll be able to design and build your own private blockchains, deploy smart contracts and work on DAPP development.
This is a free course that can be found on Pluralsight and will teach you how to develop decentralized apps using Ethereum. It doesn’t require any prior experience and is taught by a world-renowned expert in the field of blockchain technology. You can try it out with a free 10-day trial.
3. Hyperledger
Hyperledger is a platform that focuses on developing blockchain technology frameworks for businesses. It was established to encourage cross-industry collaboration and provide high-quality solutions for organizations that need flexibility, scalability, and security.
It is an open-source software that provides a number of tools for developing distributed ledgers and smart contracts. The platform enables developers to build and deploy applications that solve specific business challenges.
For example, one can use a sample Hyperledger Composer to create a blockchain-based supply chain network that helps facilitate trade of perishable goods between producers and shippers. This includes defining individual roles for each participant, executing terms of agreement, and tracking shipments.
In addition, a blockchain network is also able to improve data access and control. It reduces the time, cost and risk involved with confidential information and operations by establishing a shared ledger that ensures trust and transparency.
In addition to its core platform, Hyperledger has a number of other open-source projects that provide solutions for specific business needs. Some of them include Hyperledger Fabric, Burrow and Indy. These projects have contributed to the development of permissioned blockchains that are easy to manage and maintain. They offer a modular architecture that delineates roles between nodes, executes smart contracts (also known as chain codes), configures consensus and supports membership services.
4. Solidity
Solidity is an advanced programming language that targets the Ethereum virtual machine (EVM). It is statically typed and supports complex programming features such as inheritance and user-defined data types.
Developed by the Ethereum team in 2014, Solidity is an object-oriented language that’s specifically designed for developing smart contracts on the Ethereum blockchain. The language is based on the ECMAScript syntax, which makes it easy for developers to understand and code.
It also supports multiple inheritance, C3 linearization, and a variety of key-value data structures. It’s a popular choice for smart contract development.
The main purpose of Solidity is to create smart contracts that are immutable and cannot be modified or tampered with. This means that when a transaction is recorded on the blockchain, it can’t be changed or deleted without the approval of the majority of nodes.
Another important feature of Solidity is its state variables. These are similar to local variables in other languages but store the value permanently in contract storage.
While the language is designed to be learned quickly, it requires a significant amount of time and dedication to learn. However, it’s a great choice for beginners and aspiring blockchain programmers. There are a few online courses that teach beginners how to use Solidity, and there are also many courses for more experienced programmers who want to learn how to develop and deploy smart contracts using the Ethereum platform.

7. Smart Contracts
Smart contracts are a type of computer program that can automatically execute the terms of an agreement without human intervention. These programs are built on blockchain technology and can be used in a variety of industries.
To build a smart contract, a developer must use Solidity, a programming language that enables developers to write code. These codes are then uploaded to a decentralized network of nodes, where a trigger event causes the smart contract to execute its terms.
A smart contract can be used in a wide range of industries, from decentralized finance to digital identity to real estate. For example, a smart contract on the Ethereum platform can be used to transfer ownership of a piece of property to a buyer when it is sold.
Another popular industry use of smart contracts is in healthcare, where it can be used to store medical records on the blockchain, creating a traceable record and protecting patient privacy. In addition, a smart contract can be used to manage access to medical records, allowing patients to control who can view their data and how long.
Smart contracts can also be used to automate billing processes, reducing the time and costs associated with invoicing. For example, a business that sells products online can set up a smart contract to send an invoice to a customer once their order is processed. This makes the process faster and more secure.
