Skills Needed to Become a Blockchain Developer
Blockchain is one of the fastest-growing technologies in the world. Most companies are trying to implement the scope of blockchain for the growth of their business. Therefore, they are looking for skilled blockchain developers who would help them to execute new technologies and to update their existing systems so that they can ensure growth in the market.
As blockchain is revolutionizing the world, there is a huge demand for blockchain developers. Without them, it is not possible to utilize the benefits of blockchain technology. The developers are responsible for all the research on the blockchain and the execution of the benefits of blockchain. Developers will be responsible for building the system’s architecture, creating smart contracts, as well as optimizing the protocols. As they need to handle a lot of responsibilities, they need to have certain skills.
- Cryptography
To offer a safe blockchain environment, cryptography is very important. Therefore blockchain developers must have a good understanding of cryptographic practices and concepts including crypto keys, wallets, and digital signatures. Developers must have the knowledge to make use of public-key cryptography to avoid unauthorized access. They should also understand the dissimilarities between the different cryptographic hash functions such as Keccak-256 and SHA-256.
- Blockchain architecture
Blockchain developers must have a good idea about the way blockchain works and its architecture. They should also know concepts like a consensus, smart contracts, distributed ledgers, and others that are very important in the functioning of blockchain technology. They should also know the four basic types of blockchain architecture – private, public, consortium, and hybrid.
- Data Structures
The presence of data structures is an unavoidable part of the whole blockchain network. Every block is a data structure type that gathers all the transactions specifically for the public ledger. Blockchain developers must study data structures thoroughly and should understand the way blockchain network makes use of data structure. Developers must also understand the different types of data structures like heaps, graphs, Merkle trees, Patricia trees, and hash trees.
- Smart Contracts
Smart contracts allow two parties to transfer services and goods without any intermediaries. Smart contracts are a predominant factor while implementing blockchains. Therefore, developers must be familiar with these smart contracts and how they can be used for business. They should also know the programming languages that are widely used in the execution of smart contracts like Chaincode, Solidity, or Vyper.
- Web development
Web development is very important as blockchain gives high importance to decentralized applications. Therefore developers must have good skills in web development like designing and developing web applications, technologies that back them up, and the steps that can be taken for the optimization and security of these applications.
- Programming languages
Various programming languages are used by the blockchain technologies and will be different according to the platforms used to execute the blockchain environment. Developers need not be experts in all the languages, but they should have some basic knowledge of some of the popular languages like Python, C++, or JavaScript. It is also good if the developers have some idea of object-oriented programming.
