Can't we make recaptcha like solution based on cryptography & blockchain

Like solutions are based on clicking image or entering text in the field which is really time consuming and labor intensive. I can still remember once I spent over 5 minutes (with some breaks) to solve recaptcha click all images captcha to login in one of my account, which I think nobody wants.

So now on topic, do any of you know captcha solution better than recaptcha and based on cryptography or blockchain? I know about coinhive proof of work captcha but is this secure to use in sites?

There aren't any at the moment.There is always a room for the project.The only problem is not many sites would want to adapt to the blockchain based solution because default captcha just does the job.Maybe in the near future crypto related projects would admire your solution.We all know the pain of google captca and I hate  it.

I agree that reCaptcha can be big problem,especially in case if you solve to much of them on a regular basis.For 2-3 months I have big problem with them,it was almost impossible to solve them,and last few days they become very easy.Maybe xx e-mails to their captcha help service have something to do with easier captcha.

I know there is few interesting captcha which are not based on clicking or text input but on slide to validate which is much easier.One captcha is is called GeeTest and the other is BitCaptcha.In first you just need to move slide and set it in right place,in second you need to click on moving ball/circle.There is also one more captcha based on slide to validate and it is much easier then GeeTest,just need to slide from left to right-but I do not know how it's called.
