Since its debut one and a half decades back, Blockchain technology has made waves across the globe. A promising technology that once only powered Bitcoin cryptocurrency today has been adopted widely across a wide range of industries further pushing its advancement and ultimately the demand for skilled professionals in IT such as developers and software engineers with Blockchain training. Blockchain development skills will not only be in high demand soon, but they will also be a necessity for businesses that need to enhance the security and compliance of their data and operations.
Blockchain is a decentralized ledger of transactions distributed across a peer-to-peer network of computers. Blockchain technology is hailed for enabling highly secure and immutable transaction records while also eliminating any possible single point of failure. Records in blockchain are stored in blocks organized in order of their time of entry and linked to each other by a hash function. Hashing is the function that makes transactions in blockchain immutable, in other words, impossible to alter once the transactions have been entered and validated. Blockchain developers play an important role in building Blockchain-powered applications.
Who are Blockchain developers?
A blockchain developer is an IT professional who develops decentralized applications that run on the blockchain network or the blockchain network itself. Common categories of applications that have benefited from blockchain technology include applications for storing and sharing medical data, personal identity, NFT market, supply chain, and logistics monitoring, cross-border payments, and voting systems and applications.
A blockchain developer has in-depth knowledge of the architecture and workings of blockchain-powered systems and demonstrates an ability to implement blockchain features or components into a system.
Roles and responsibilities of blockchain developers
Blockchain developers are responsible for developing and maintaining secure blockchain networks, applications that run on the blockchain network, or both.
They may be called upon to work together with the software engineer or systems analyst to help with the design phase of applications or networks and analyze existing systems and applications. Other blockchain developer roles include:
- Working with managers and other stakeholders to determine the requirements and functionalities of blockchain technology in the organization
- Designing, developing, and distributing blockchain network decentralized applications, application features, interfaces, consensus protocols, and other customized blockchain technologies.
