Blockchain Technology Overview
The Blockchain serves as a digital ledger that records all transactions, and these transactions are visible to all the participants in the Blockchain network. Any malicious hacker trying to break into the system will have to change every block in the chain across all distributed versions to do so as every participant has a record of all transactions that occur in the network. If one block in the chain is tampered with, it becomes very obvious and noticeable, which makes it highly secure and immutable.
These blocks contain the following three categories of information:
- Transaction data such as date, time, and amount
- A digital signature for a name to avoid giving out identifying information
- A unique code called hash (an immutable cryptographic signature)
Blockchain technology makes tracking easy for any tangible or intangible asset in a business network. Anything that is of value virtually can be tracked safely and at a cheaper rate on the Blockchain network.
Who is a Blockchain Developer?
Simply put, Blockchain Developer is the one who develops the Blockchain. There are two kinds of Blockchain Developers:
- Core Blockchain Developer: Responsible for designing the security and architecture of a Blockchain system
- Blockchain Software Developer: Uses the core web architecture to create apps, specifically the decentralized applications (Dapps), and web varieties.
Sometimes, in smaller businesses, the same person may fulfill both roles.
Blockchain Developer Responsibilities
Blockchain Developers are responsible for creating innovative solutions with high integrity, command, and control. They are in charge of performing the design, computer system selection, operating architecture integration, development, complex analysis, testing, and debugging.
Blockchain Developers are able to operate on multiple systems and are proficient in one or more programming languages as well as platforms.
Following are some of the typical responsibilities of a Blockchain Developer:
- Design protocols for the Blockchain and the network architecture
- Backend development as per the specific protocols
- Create front-end designs for clients
- Build and monitor smart contracts
Challenges Faced by a Blockchain Developer
- Legacy infrastructure has limitations that make it challenging to meet the expectations essential in a Blockchain development project.
- In Blockchain development, there are processes that require skill sets that are beyond traditional IT development ones.
- Blockchain Developers must understand the practicality of cryptosystems that are decentralized from a technical perspective.
How to become a Blockchain Developer?
If you are completely new to the field and have no prior knowledge of programming and development, you may have to start from scratch. Though it will unroll a long road ahead of you, it is not impossible. Everyone has to start at the bottom before they can reach the top. Try and learn about Blockchain development as much as you can, starting from why it was required in the first place to the future of Blockchain technology.
If you were in a similar or relevant role in an earlier career or have previous knowledge of the domain and programming, you will be easily able to upskill and learn all the essential concepts of Blockchain development. Meanwhile, some companies are adopting Blockchain technology and providing the necessary upskilling opportunities for their employees.
