Updated for 2026: Build a blockchain and cryptocurrency like Bitcoin with Python, JS, React, and more!
InstructorDavid Joseph KatzThe curriculum builds a functional blockchain by incrementally adding features like hashing, difficulty adjustments, and digital signatures to a base structure.
Instruction bridges the gap between a Python backend and a React frontend, demonstrating how to connect decentralized logic to a modern web interface.
The implementation focuses on a centralized model, omitting the peer-to-peer (P2P) networking found in traditional blockchain systems.
Learners have reported conflicts between updated Python libraries and the provided code, sometimes requiring manual dependency downgrades to run the Flask server. This signal predates the displayed course update; the update may have addressed it, but the update label does not prove that it was corrected.
The practical application lacks a comprehensive mining endpoint for transaction pool data, focusing instead on a simpler retrieval method.
The curriculum aligns well with the goal of building a full-stack blockchain project for a portfolio.
