In simple words, a blockchain developer is a programmer who makes various products using blockchain technology - smart contracts, protocols and decentralized platforms, as well as cryptographic tools.
Depending on what duties and tasks are, there are two types of specialists:
• Basic blockchain developers - responsible for the architecture of the blockchain: create a consensus protocol, design the network and control it, monitor the security of the network.
• Blockchain software developers - are engaged in the development of decentralized applications (dApps), using the already existing developments of the basic developers.
Blockchain developer must:
• be able to program in several programming languages: Java, C++, Python, less often JavaScript, Ruby and C#;
• understand cryptography to make the network secure;
• create smart contracts;
• understand data structures; these are the “bricks” that make up the blockchain network;
• understand the types of blockchain architecture;
• understand network protocols;
• develop web applications, as most often you will be developing dApps;
Blockchain is a revolutionary technology that fundamentally solves the problems of security and trust. All data and operations are transparent and cannot be changed or stolen. Transactions can be carried out without intermediaries. This significantly reduces business costs, so large companies are increasingly investing in this area.
The demand for specialists like https://unicsoft.com/blockchain-development/ will only grow, because more and more companies understand the benefits of technology, new projects are constantly appearing and investments are increasing.
