Neat! This does seem like it should work!
Semantic quibble: it's less "proof of work" and more "proof of hardware+work". Or, as they call it, hardware-bound proof of work. The reason you can't offload the challenge to a more powerful device is that they rely on identifying stable differences for each device class that ultimately trace down to the hardware they're running on.
- mindslight 4y agoFrom reading the abstract, isn't this just exploiting the same class of security vulnerabilities that the OP is lamenting are being fixed?
- jefftk 4y agoNot sure. Maybe not, if it's about device-specific information instead of headed-vs-headless distinctions?
