Projected to become a global market worth over $20 billion by the year 2025, Blockchain Technology is currently the most trending conversation. Bitcoin has demonstrated how strongly it can improve security and privacy and with Ethereum, we are able to create self-executing protocols called Smart Contracts enabling transactions to occur digitally and safely even in the absence of trust.
Beyond finance, Blockchain sets to reinvent industries from Medicine, Education, Aviation, Computation, Governance, Cyber Security, and more. Blockchain technology is gradually evolving the web from Web2 to Web3.
Individuals are constantly coming up with new Web3 and Blockchain Ideas that require developers to implement and there are Investors who are betting their money on these ideas which also implies a lot of money for Developers.
The demand for good blockchain developers is high and constantly increasing with every new protocol, idea, or implementation in the space.
A Blockchain Developer is a tech professional with the proper understanding, knowledge, and skills required to develop protocols, smart contracts, decentralized applications based on blockchain, and blockchain architecture.
in simpler terms, Blockchain Developers build blockchains and applications that run on those blockchains.

Blockchain Developers are majorly classified based on their skills and responsibilities. here are some of the roles & responsibilities;
These developers design, develop, optimize and maintain the architectural protocols that enable a blockchain successfully run. They ensure a blockchain is secured, and operational, extending the functionality as well as implementing features that support integrations of other services with the blockchain network.
Examples are the bitcoin core contributors, Ethereum core contributors, Polygon core contributors, and more.

These developers develop decentralized applications(dApps) and smart contracts that run on Blockchain architecture. They create mostly end-user applications for various industries and implement features that support integrations of other services with the blockchain network.
Examples are the Trustwallet Developers.
Understand Blockchain architecture
Learn about blockchain, blockchain security, application, limitation as well as challenges. Understand blockchain consensus, hash functions, and distributed ledger technology and read various blockchain whitepapers to know more about their architecture. Ethereum, Bitcoin, Polygon, and Hyperledger are some of the most popular ones.
Data Structures
As a Developer, You must have a proper understanding of data structures like linked lists, binary trees, heaps, hashes, and graphs. Learning data structures enables your dApps based on requirements.
Smart contracts & Solidity
Blockchain networks are powered by smart contracts and allow you to set the logic of your dApps. Smart Contracts are a set of rules that must be agreed upon by all parties involved in a dApp and run under certain conditions. It is usually built using Solidity, a high-level programming language with syntax similar to that of JavaScript. Learn solidity here.
Basic understanding of cryptography
Blockchain adopts cryptographic algorithms for data protection. Understanding cryptographic theory, digital signatures, hash functions, and RSA algorithm helps you implement smart contracts and dApps more accurately. Learn cryptography here
Cryptonomics
Understanding cryptography isn’t enough. It is necessary to learn about cryptonomics which are the concepts of “cryptography” and “economics”. It focuses on the use of economics and cryptography to manage the functions of participants using a network and learning about it helps you understand transaction cost, mining, and the transaction lifecycle better. Vitalik - Founder of Ethereum explains cryptonomics in this video. You can also read Cryptonomics: A Modern Investors Guide to Cryptocurrency Markets and Blockchain Literacy.
Programming
Solidity is recognized as the main backend language for blockchain development and for the frontend aspect, you can utilize HTML, CSS, JavaScript, or whichever of it frameworks you decide although in many cases React. Python, R, and Simplicity are other backend languages you can use to code your smart contracts.
Trading and Investing Concepts
While you are trying to become a developer in web3, It is also necessary to understand how traders and investors interact with blockchain, place trades as well as currency and market price variations. Understanding trading concepts helps you build better dApps for traders and investors.
