Trigger when the user wants to learn, implement, debug, or extend a build-your-own project for 区块链 / 加密货币 using Java. Use when they mention "build your own blockchain-cryptocurrency", "用 Java 创建你的第一条区块链", the source URL, or ask for a Claude Code guided implementation plan. Guides the user through a project-based learning workflow: inspect prerequisites, create or adapt a minimal project, implement milestones, run verification commands, and debug failures without simply dumping a full finished solution.
