Exploring Developer Roles in Web3
Building for the Future: Developer Roles in Web3
Looking to be part of the industry of the future? You’re in the right place. With unprecedented growth and opportunities aplenty, many companies are now looking to hire Web3 developers. For developers looking to transition to web3, here are some of the roles you can consider exploring.
- Blockchain Fundamentals
- What is Web3
- Types of Developers
- Core Blockchain Developers
- Solidity Developers
- Blockchain Application Developer
- Blockchain Architect
- Smart Contract Developer
- DevOps Engineer
To become a web3 developer, one must first understand the blockchain’s basics. It’s essential to comprehend this technology to efficiently build and optimize smart contracts.
A blockchain is a public, decentralized, and immutable database owned by its users. Data is stored in blocks that are chained together, hence the name “Blockchain.” Each block contains its hash, data, and the previous block’s hash.
The hash is a unique string generated from the data and changes with every alteration. If someone alters a block, the chain breaks, and the following blocks become invalid.
To restore the chain, one must recalculate all blocks, which takes a considerable amount of time (about ten minutes per block). Copies of the blockchain are stored on nodes worldwide.
To perform this process, access to a majority of computers is necessary since a single computer is too slow to go unnoticed by the network.
What is Web3
Web3, the latest iteration of the internet, is distinguished by its decentralized networks and utilization of blockchain technology. In contrast to the static nature of Web 1.0 and the more user-centric features of Web 2.0, Web3 raises the bar by offering autonomy, transparency, and security. It represents not just a technological advancement, but a fundamental shift in paradigm. With any application built on Web3, users have ownership and play a crucial role in creating and maintaining decentralized applications (dApps), which are the future of the tech industry.
To become a competent Web3 developer, one needs to possess a thorough understanding of the concept of Web3, the relevant programming languages, and the appropriate tech stack.

All types of Web3 developers should have a good understanding of encryption and security, as one of the strongest points of blockchain is increased system security. Finding a developer who can both build and protect is both challenging and expensive. After all, they must have a proven track record of implementing secure hash algorithms, encryption, and decryption techniques, public and private key concepts, and identifying rapidly changing vulnerabilities.
