Blockchain technology has drawn much interest and is being adapted into every vertical like banking, Fintech, accounting, cryptocurrencies, the stock market, and real-estate segment, because of its efficient record keeping in distributed ledgers with transactions that are safe, secure and efficient. There is no third-party involvement anywhere in the process and records can be viewed by the public, building a trustworthy secure payment system.   

Opportunities abound, and many Fortune-500 companies like Capgemini, IBM, Accenture, etc. are headhunting. Indian salaries range according to Glassdoor in the range of Rs19 to 21K in India for fresh candidates and Rs 288 to 313K for the experienced at higher levels. 

Technical skills required:

Code:

Blockchains run on code and is essential for logical interpretations and quantification.

Programming languages

Blockchain technology uses languages like OOPs, flat and relational database and procedural language. Also required would be programming languages like C, JavaScript, and C. 

The architecture of blockchains: 

Essential knowledge here would be the Bitcoin whitepaper, consensus, cryptographic hash functions, and distributed ledgers in blockchain fundamentals, its architecture and working. Decentralized architecture also means inexpensive perfect coding, MVC, Document-view, MVVM, fundamental communication architecture, G and bus architecture, and convention theory used for decentralizing the architecture and a fair understanding of fundamentals of distributed and centralized networks.

Structures of Data: 

Knowledge is required of data structure like Stack, Merkle trees, Patricia trees, advanced cryptography and a large number of data structures, Queues,  LinkedList, Tree, Hedera HashMaps, etc. is essential to understand how the language, technology, and data structure works.

Cryptography:

Methods of advanced cryptography like the hash functions ( KECCAK256, SHA256, etc.), sound knowledge of data structures, and a digital signature generating asynchronous cryptography are a must.

Development of Smart Contracts:

Functionalities of smart contracts to enable the business logic application of the blockchain, and specific network languages like Ethereum’s Solidity, Chaincode, Viper, etc.

Platforms and frameworks:

Coding for platforms like HashGraph, Hyper Ledge, Ethereum, EOS, etc.

Fintech Course

Web-Development:

To develop applications that are de-centralized, both front and back application development including handling APIs, Dapps based interactive GU interfaces, handling requests, etc.

Smart Contract enablers

Truffle suite installation and working on Mac, Windows, and Ubuntu.

Passion and technical skills will need to be combined. Read and learn about the history besides making a portfolio of small projects using the blockchain technology. You could also hone your skills at a reputed institute which is quite advantageous to you. A good blockchain training course will necessarily focus on a global curriculum; hands-on practical and project work which will help you build your industry and vertical relevant portfolio. Follow the protocol, do your fintech course at a reputed institute like Imarticus, learn at your convenience and get set to be career ready as a blockchain developer. The more you research, the better you learn. Continue enhancing your GitHub profile, attend the hackathons, and never quit.
