The article from Bloomtech discusses the essential skills developers need to transition from traditional Web2 development to the emerging Web3 paradigm. The article argues that while Web2 skills are valuable, additional proficiencies are needed to navigate the decentralized world of Web3 effectively.

Web2 Skills:

  • Front-end Development: HTML, CSS, and JavaScript are still foundational for any web project.
  • Back-end Development: Familiarity with server-side scripting languages like PHP, Python, and Java.
  • Database Management: Knowledge of SQL and NoSQL databases.

Web3 Specific Skills:

  • Smart Contracts: Understanding of smart contract programming languages such as Solidity.
  • Decentralized Apps (DApps): Skills in building decentralized applications on platforms like Ethereum.
  • Blockchain Basics: Fundamental knowledge of how blockchain technology works.
  • Tokenomics: An understanding of how to design and deploy tokens within the ecosystem.
  • Cryptography: A basic grasp of cryptographic techniques used in blockchain technology.

Overlapping Skills:

The article suggests that some skills are transferrable from Web2 to Web3. These include:

  • UX/UI Design: Designing user-friendly interfaces remains critical.
  • API Integration: Working with APIs is still relevant in the Web3 space.
  • Security: Concepts like authentication and authorization are still vital but take on new forms in decentralized networks.

Key Takeaways:

  • Developers interested in moving from Web2 to Web3 will find their existing skills useful but will also need to acquire new proficiencies.
  • Web3-specific skills such as smart contract development, DApps creation, and understanding tokenomics are increasingly important.
  • Familiar Web2 skills in UX/UI design, API integration, and security can be adapted for the decentralized environment of Web3.


  1. Are Web2 skills obsolete in the Web3 environment?
    • No, many Web2 skills like front-end and back-end development are still relevant but must be adapted to fit the decentralized model.
  2. What are the new skills required for Web3?
    • Smart contract development, DApps creation, and a basic understanding of blockchain technology and tokenomics are critical for Web3.
  3. Can Web2 and Web3 skills co-exist?
    • Yes, some skills like UX/UI design, API integration, and security are transferrable and can be adapted to both paradigms.
