Doesn’t have to be a crypto miner. Just has to be any sort of computationally intense task. I think the ideal would be some sort of JavaScript that integrates that along with the captcha.
For example, have some sort of computationally difficult math problem where the server already knows the answer, and the answer is then fed into a simple video game engine to procedurally generate a ‘level’. The keyboard and mouse input of the player would then be fed directly back to the server in real time, which could decide if it’s actually seeing a human playing the correct level.
