A blockchain developer manages the lifecycle of an application created using the technology of the same name. He or she builds the architecture of the system, installs smart contracts (special transaction protocols called Smart Contracts) and optimizes them.
Blockchain developers have two specializations:
Blockchain software developer.
Core blockchain developer.
Both do basically the same thing, blockchain development, but they have different responsibilities.
Blockchain software developer.
He creates applications based on the architecture and protocol of the system, which also run on blockchain. It can be compared to a web developer who builds on what a web architect has already created and develops his own product – new web applications.
Blockchain software developers create DApps (decentralized apps, similar to regular mobile apps). They are responsible for the interface (external) and internal (backend) development of DApps within the stack on which the apps run.
Blockchain engineer
This developer is responsible for creating the architecture of the system. He or she oversees the network, develops the consensus protocol, and makes most of the vital decisions related to blockchain. Engineers are responsible for the security of their blockchain network.
Many experts say that blockchain is what the future holds. It is a unique and revolutionary technology that solves data storage security problems. Every transaction in the chain is transparent, nothing can be tweaked for profit or stolen.
Another advantage is decentralization. This means that every transaction is done without intermediaries. Thanks to this, various sectors of business can significantly reduce costs.
Because the technology is in demand and will only grow in the future, it needs people working with it – which is what blockchain developers are doing. There are already more than 150,000 job openings in this field on LinkedIn (a social network for finding and establishing business contracts). The demand for employees is high, but the specialists themselves are still few. And the demand for programmers in this field will only grow.
