Have a "CAPTCHA" that gives the IP reputation for some time (cookie+IP=key), but instead of a CAPTCHA make the web page / browser solve and submit a BOINC task from a randomly picked science project. No user interaction needed, it has the benefits of "paying by computation" of cryptocurrencies without the tracing, and if bots solve the problem efficiently, it's good for science.
- rapnie 4y agoThat is a nice idea. So bit similar to mCaptcha [0] that uses PoW algorithm, mentioned in other comment [1] in the thread. [0] https://mcaptcha.org/ https://mcaptcha.org/ [1] https://news.ycombinator.com/item?id=32339902 https://news.ycombinator.com/item?id=32339902
- zakki 4y agoCan we make a bot to mine a cryptocurrency?
- GTP 4y agoIt's called miner and you can already install it on your pc.
- GTP 4y agoBut solving a BOINC task requires too much time while the average user rightfully expects a webpage to load within 5 seconds or so
- david_draco 4y agoUsually you have a landing page, and then you enter stuff there, and finally you get output. That gives you about 1 minute before returning first results. If the user is faster, you can show something like cloudflare does when you visit through Tor. On later submissions you can reuse the reputation from the cookie.
- GTP 4y agoStill, 1 minute is far from enough to solve a BOINC task.
