What are the prerequisites to starting a course in blockchain technology?


The prerequisites to starting a course in blockchain technology are the same as those for any other subject. You should have basic knowledge about C, C++ and Java, know why blockchain is useful, be interested in blockchain as a technology and be comfortable with data structures and algorithms. Blockchain is a technology that enables the creation and exchange of highly secure digital assets. A blockchain consists of a network of computers that store and synchronize data, with each computer connected to the others by way of a distributed ledger.


You could say that it's like a giant spreadsheet where all the entries are encrypted and cannot be edited or deleted by anyone but the original sender. This means that once information has been added to the blockchain, it can't be changed without also changing every entry after it — which would mean rewriting all previous entries as well! If you have basic knowledge about these subjects and are interested in learning more about them then we can definitely help you start a course on blockchain.


The blockchain is a series of records that are linked together in a way that allows for verification without the need for a third party. The blockchain ledger keeps track of all transactions made on the network, which makes it harder to falsify information or take advantage of people.


A blockchain has features that make it very useful for data storage and management:


  • It's decentralized — there's no central authority or trusted third party that can alter data stored on the network.
  • It's public — everyone can see what's stored on the network and can access it if they want to do so. This makes it easier for people with different needs to collaborate with each other because you don't have to trust anyone else in order to share information with them (you can verify their identity).
  • It's secure — you're able to encrypt your data so that only those who have access can read it, which prevents others from altering what they see and making false claims about something being true when they know better than anyone else does (for example, claiming someone owes them money when they haven't


Foundational Technological Competence and Expertise

To become a blockchain developer, one should start understanding a few skills. The  user should be well-versed in internet technology, data security, and computer programming. A beginner blockchain programmer should have a strong grasp of distributed applications, networking, cryptography, and data structures.

Networking and distributed systems

Blockchain is a distributed ledger that operates across a network, and an individual should be familiar with the network and distributed system. Understanding how peer-to-peer networks work is essential. It aids in the establishment of a solid foundation in a computer network, which can include everything from routing to network topologies. Data is collected and distributed among the connected users in a decentralized manner by distributed systems. The distributed system enables data to be shared across networks concerned with data. The primary benefit of a distributed system is that it improves real-time data updates because the data is shared across nodes that have a copy of the blockchain.


Cryptography is the groundwork of Blockchain, and it is where the cryptocurrency got its name. The Bitcoin blockchain employs public-key cryptography to generate hash functions and message authentication. A strong mathematical foundation can also be advantageous in the field of Blockchain development. Blockchain technology relies heavily on cryptography. It assists the blockchain programmer in safeguarding the data against security breaches. This is performed on two levels, one being the key-encryption method and the other being hashing. Cryptography's purpose is to prevent data from potential hackers. When information goes into the system, it is secured and stored in a block, which is then chained together to form a network.

Data Structures

To understand about the complicated nature of Blockchain, one must comprehend the data structure. The data in the Blockchain is kept in the form of blocks rather than tables. Databases are replicated across the entire network, which is known as distributed ledger technology. A blockchain programmer should understand how data structures like linked lists, graphs, hash maps, search trees, and others function properly. The ability to create a data structure from scratch is also required for a blockchain programmer. Programming languages such as C++, C-Sharp, C, Scala, Java, and Python are also needed. The GitHub repository contains all of the essential knowledge regarding data structures and algorithms.

Smart Contracts

Blockchain technology and smart contracts go hand-in-hand. A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as "completed" blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.


Smart contracts are applications that aid in the automation of money transfers. It contributes to the advancement of Blockchain capabilities by eliminating the need for middlemen or lawyers to settle transactions. Smart contracts are created under specific conditions or in specific circumstances. The details of a smart contract are encoded in the pattern of a code, and these codes are not randomized; rather, there is a technique or series to this configuration. One of the main benefits of smart contracts is that they can help to reduce counterparty risk. Because the terms of the contract are encoded in code, both parties can be confident that they will receive what they are entitled to. This is in contrast to traditional contracts, which rely on trust between the parties involved. Another benefit of smart contracts is that they can help to automate complex processes.

Decentralized Applications

Some decentralized applications (DApps) are built on blockchains. A blockchain developer can build a DApp on a variety of platforms. Here are a few examples of popular Decentralized Applications:


The permissioned network makes it simple for companies to sign up customers by providing transaction jurisdiction and identification access, defining a large area in which the consumers can then collaborate and requiring new users to take authorizations. The platform includes data partitioning capabilities, enabling businesses to save information that would normally be perceived as sensitive due to various legal ramifications. The primary goal of Hyperledger is to develop cross-industry Blockchain technologies on an open-source collaborative platform. Hyperledger is not a cryptocurrency, blockchain, or an organization; rather, it facilitates the development of an ecosystem, environment, or infrastructure for a successful blockchain system, etc.


EOS is an abbreviation for Electro-Optical System. The EOS blockchain's primary goal is to support industrial-scale applications. It is a decentralized operating system with greater scalability and transaction speed than Ethereum. EOS is a blockchain-based platform that makes it easier to develop, build, and run business applications. EOS enables DApps to communicate in a secure and authorized manner. EOS also enables business applications to create secure, authorized applications in the same way that web-based applications do.


The platform serves as the foundation for the advancement of the dominant part of decentralized applications on the market today, particularly in enterprise settings. The possible explanation for the Blockchain world's complete trust in Ethereum is the platform's multitude of advantages, including protection and safety, consistency, zero downtime, and fraud protection. Ethereum is used in the development of digital and secure technology. It offers tokens for use on the blockchain technology platform. It enables the decentralization of functions that are safe to use. It is one of the reasons why blockchain developers use Ethereum. The Ethereum platform has its own cryptocurrency, ETH or ether. Ethereum is a blockchain-powered platform where ether is the Ethereum currency.



No one can deny that the Blockchain is the best technology that many industries will be based on in the future, given how much it has grown in just a few years. Understanding technical knowledge is one of the skills required to become a blockchain developer.
