Let’s go through the fundamental abilities needed by a blockchain developer.


In the blockchain world, cryptography is used in the form of protocols to prevent unauthorized access to data. For example, public key encryption may be used to protect bitcoin financial transactions.

Smart contracts

Smart contracts eliminate the need for intermediaries in the transaction of goods and services. They can only be carried out if both parties follow the contract’s terms.Smart contracts’ efficacy is essentially determined by the blockchain’s decentralized character.

Construction, law, and other areas of the national economy employ smart contracts.

Structures of data

The blockchain network is made up of data structures, and a block is a data structure in the broadest meaning. It groups transactions for a blockchain, which is a public ledger.

A blockchain developer needs data structures because they aid in understanding the underlying operation of a block.

The architecture of the blockchain

The core notion of blockchain is architecture. There are three sorts of it that a developer should be familiar with:

  • The private blockchain architecture is a popular option for businesses since it is ideal for use cases with a small number of participants.
  • The consortium’s structure isn’t entirely decentralized. The members of the group, which is made up of many organizations, have complete control over this situation.
  • A high amount of decentralization characterizes the public blockchain design, allowing you to engage in the network via transactions or mining.The most famous example of such an architecture is Bitcoin.

Web development

In most cases, a blockchain programmer will be developing web applications. He will also need to learn web design and other tools to create quality dApps.

Customers require blockchain developers to create applications that can be easily used by even people with minimal blockchain knowledge.

Network protocols

Another important component of blockchain technologies. Protocols define how data is structured and establish precautions to prevent malicious users from harming them.

Blockchain protocols allow network nodes to securely exchange information over the Internet. It is important to understand that there are hundreds of protocols, so learning them will take a huge amount of time. Here are five main protocols that are currently relevant:

  • Hyperledger;
  • Multichain;
  • Enterprise Ethereum;
  • Corda;
  • Quorum.


Blockchain developers often solve complex problems related to applications and blockchains. The need for such specialists in the labor market is constantly growing, but it is rather difficult to master the necessary knowledge on your own. There is not so much necessary literature, tutorials and courses in the open access, besides, most of the content is published in English. To confidently solve problems in the blockchain field, you will also need practical skills, which are almost impossible for a beginner to acquire without participation in real projects.
