Blockchain developers should know the basics of the technology. The lion’s share of difficulties and limitations in development are caused by its peculiarities and limitations. In particular, to create a quality product, a developer must understand the principles of blockchain decentralization and autonomy. It will also be necessary to understand the problems of scalability, understand the features of P2P networks and have knowledge of the principles of HTTP requests.
Blockchain development on Etherium smart contracts or any other platform created for that purpose is easier and as such, no knowledge base is needed.
Smart contracts are a ready-made tool for developers, which ensures the fulfillment of the conditions put into it, which must be entered by the programmer. The main difficulty that may face a novice developer of smart contracts – the lack of training materials. At the same time, creating a smart contact is a highly responsible task, because even a minor omission in the code can make the system vulnerable to hacker attacks.
Programming and coding skills are not enough to create your own blockchain architecture. A developer must know all the key features of the technology. This will require additional study of:
The basics of blockchain and its types;
principles of work and chain building;
cryptography and hashing algorithms.
Blockchain is an open technology and most information can now be found on your own. You can learn for free, as most blockchain projects have open source code, which is available for study on the GitHub service. But if you focus on the speed of learning, you should pay attention to courses for developers, as most open-source information gives only superficial knowledge, and you will have to spend enough time to filter the data.
On the other hand, when attending courses, there is a chance to simply adopt the knowledge of the teacher and copy his actions, so the best option is to attend courses, combined with self-study.
