This is the first CAPTCHA replacement that I really like. Adding a delay that costs computing power will both slow down and add real costs to spammers (though if it's a bot net they'll not care about the latter). I really dislike how impossible CAPTCHAs have become, and the slew of startups working on advertising based ones is not the solution the users want. As a user, all I want is ease. I'm fine waiting a few seconds... just don't give me an impossible task to perform or use the inconvenience you've created as an opportunity to advertise. All I want is to do whatever I wanted to do, read, write... I can wait a moment, just don't make it painful.

This was a reason I made this project. Thank you for great feedback! :)

  I really like that it works fine on my mobile too. Have you done tests on many platforms to show which ones are supported? I'd probably like it to be more automatic... a single clickable progress bar without the need for the 2 text fields or generate button. But yeah... this is ace.

    I created jQuery plugin with that kind of widget, but really, any type of widget can be built on top of it. What jquery plugin does - used API library to communicate anyway, so if people will want different type of widgets - they will come. As for support on different platforms - Safari is tricky one right now. Trying to figure out why it is not working. IE before version 10 will not work, because it uses typed arrays in javascript. Other than that it should work in any modern browser in theory.

  Thank you for making it. (I'll beg you for an invite later.) I'd experimented with embedding Javascript Bitcoin miners in my website as a means of monetization without ads. I see this as a more intuitive version of that which restricts the user based on usage (posting rate) instead of on viewership. The issue I encountered was a miniscule rate of return on the JS-based mining. Do you think that if HashCash integrates with BitCoin for monetization/mining purposes, JS speed will be a limiting factor?

    To be precise, right now it uses Dogecoin proof of work. I got it running pretty good with asm.js compiled scrypt miner code. In future I will need to solve scaling problem, as right now it runs with fixed 2 threads only. In future it will self adjust based on user computer performance. Right now there is no payouts to webmasters, but this is next feature I am working on. It will be made directly to webmaster dogecoin address from p2pool I am running for this project.

      Woww. Such clever. Much compile. I've been trying to get Hamiyoca's JS miner to work with mupool without much success. (Stratum is straitforward. I'm just dumb.) p2pool is way easier from the cursory glance I've given it. I'm surprised I hadn't heard of it before. Any chance I could trouble you for an invite for jo.jcat at gmail? I'm already using proof-of-work to keep spam off my blog (josephcatrambone.com), but I wouldn't mind switching early to something more conducive. Hell, if the payouts are nonzero when they roll around, I might be able to strip the ads. Alternatively, what's the official way to request an invite? Sign up for the news letter and wait?

        basic dashboard is out there, but payments are not yet. there is not much stuff behind login form yet :) so yeah, i would rather develop it further before letting people signup for it. till then you still can use it as a proof-of-work solution using keys generated on home page :) I will definitely email invite codes to everyone once it is ready to go.

I actually dislike it for the reasons you stated. I don't see this negatively impacting a botnet at all while still annoying regular users with the delay. Also, even if they are paying for it, the "proof of work" is probably less expensive as captcha breaking. What I'd really like to see is a more sites that do analysis to block bots, rather than annoying users. Spammers generally need to place a link and do so quickly. It seems much easier to target people who post links in their first 5-10 posts than to do anything else.

Same here. First time in many years that I don't say to myself "bullshit" while looking at a purported solution to the captcha problem. The solution is at once obvious and very clever. What is the most unexpected is that it doesn't tell humans and robots apart at all. The CAPTCHA word may have blinded us to more general / obvious ideas.
