Browser mining: archived XMR tutorial
This post originally explained how to add an XMR web miner to a website. I have converted it into an archived, educational guide because the old approach is no longer a good recommendation: it depends on fragile mining scripts, creates a poor user experience and is commonly blocked by browsers, antivirus tools and content blockers.
The useful lesson
The interesting part is not the revenue promise. It is the engineering trade-off: a website can run heavy work in the browser, but doing so shifts energy cost, heat and performance loss to the visitor. That requires explicit consent, clear controls and a very strong reason.
A safer pattern
For a modern educational page, show a simulation instead of connecting to a real mining pool.
Review checklist
In this project the practical replacement is the educational proof-of-work simulator: open the simulator.
