Blockchain technology continues to advance and revolutionise the way the digital world manages data and does business. It has made its way into many sectors, going far beyond its roots in the world of cryptocurrencies. The rise of this technology has created a need in many of these sectors for professionals with skills in this field, what we know today as blockchain developers.
The demand for developers with the necessary skills to create blockchain networks and decentralised applications has increased enormously, which has led many people to consider a career in blockchain development.
But how does one become a blockchain developer and what characteristics does this profile have to meet?
we tell you all about it in this post!
what is blockchain?
Blockchain technology is a type of database used to store and organise information. Traditional databases organise information in rows and columns that form tables. This makes the information easy for computers to recognise. However, with blockchain technology, the information is digitally formatted and grouped into sets or blocks. Each block has a limited storage capacity.
Once that capacity is reached, the block is closed and linked to the previous block using cryptography, creating a chain. Cryptography creates an unalterable timestamp when one block is linked to another. This permanent record verifies the accuracy of sensitive information such as transactions. In contrast, traditional databases are usually controlled by a central authority. Sensitive data can be managed and maintained by an organisation or an administrator.
what is blockchain development?
Blockchain development refers to the creation, maintenance and design of blockchain applications and systems. In general, it is about using the unique features of blockchain technology to solve problems and create opportunities.
One example of an innovative blockchain development is the smart contract. Smart contracts are documented agreements between two parties, just like ordinary contracts. However, unlike ordinary contracts, smart contracts are also programmes stored on a blockchain. These programmes are triggered to execute only when both parties fulfil the agreed terms and conditions. This automated fulfilment ensures the correct execution of a contract in real time.
Comparing smart contracts to parking meters is a good way to conceptualise their usefulness. Once the correct payment is made, you automatically receive the parking validation corresponding to that payment. There is no need for third party intervention, such as a cashier, because the agreement is fixed.
what is a blockchain developer?
Basically, a blockchain developer is someone who is responsible for creating and improving blockchain protocols. He or she is someone who uses blockchain technology to design the structure of blockchain networks. Among his or her functions, he or she is a person capable of developing smart contracts and web applications.
There are two main types of blockchain developers:
- Lead blockchain developer
The duties of this type of blockchain developer are to design the blockchain architecture, blockchain protocols, consensus protocols and security system for the network. This type of blockchain developer will also have the responsibility of overseeing the entire network and driving advanced decisions associated with blockchain technology.
- Blockchain software developer
This second type of developer is responsible for the development of smart contracts, interactive front-end designs for decentralised applications and blockchain back-end. A blockchain software developer will also oversee the entire stack that operates its Dapps. It employs the structure and mechanisms designed by the lead blockchain developer to develop decentralised applications that operate on blockchain networks.
Characteristics a blockchain developer should have
Regardless of the type of developer, if you want to become a blockchain developer you must meet a number of key skills and requirements:
-
Understand the fundamentals of blockchain
First and foremost, you will need to understand the fundamentals of blockchain technology. Acquiring basic knowledge will prepare you for more advanced topics and specialisations. It is similar to the way you need to know the basics of cooking before attempting a complicated dish.
Build your skill set (and enhance your resume) through courses, certifications or a degree in computer science. There are many different paths to becoming a blockchain developer, so take your time and find the one that suits you best.

Learn essential skills
The following list covers some basics for blockchain developers.
- Programming - As mentioned above, coding will be the framework of your blockchain development experience.
- Programming languages: Expand your skill set by learning some of the most common programming languages used by blockchain developers. Python is one of the most popular languages in blockchain development due to its versatility.
- Cryptography: Cryptography is an integral component of blockchain technology. It protects sensitive information by ensuring that the content of a message can only be seen by the intended recipient.
- Smart contracts: As mentioned above, a smart contract is a programme stored on the blockchain. Automated fulfilment allows two parties to execute agreements without an intermediary.
- Data structures: For blockchain developers to successfully build and implement networks, they must be able to work with a variety of data structures, such as Merkle trees.
- Understanding each type ofblockchain architecture is helpful in identifying an area of professional focus.

Familiarise yourself with the blockchain development industry
Although blockchain development is one specialisation, it encompasses several areas of interest. Take a look at the above list of specific skills or topics in the blockchain world and find out which one most appeals to you. Reading blogs or watching YouTube videos about that specialisation can help you keep up to date on industry trends and in-demand skills. You can also follow industry leaders in the field you are interested in on social media.
-
In-depth knowledge of data structures
A person interested in the field of blockchain development must understand the fundamentals of data structures, as well as how to apply this knowledge. Without the knowledge of different data structures, a blockchain developer will not be able to use advanced cryptography to design a secure and immutable blockchain.
