I don't know if this will work, but a friend of mine told me about it and he's made a little something with it. Granted he is paying for some of the things he needs with bitcoins from merchants that accept them.
It's different, interesting & I'm always the curious type to see how things work. So I went to the bitcoin plus site and signed up. Then I started to look around to see what other information the site had.
From what I can figure, my cpu and others are given a puzzle to solve. When the puzzle is solved the cpu's share a portion of the 50bitcoins that's the reward for solving it. Sounds simple enough.
Puzzles get harder, but by adding more cpu's into the pool it can help increase the chances of solving it sooner. So I have given my link to my sister and my kids. They have their computers up all the time, yet are not always doing something on them. So they simply go to the link and shrink the page. Then forget about it. Meanwhile, their cpu in on the site helping to work out the next puzzle in my pool.
I've only just started so I don't know how long it will take to generate the bitcoins yet. But I'll let anyone know if it pans out.
If anyone wants to help generate bitcoins for me, they can go to http://www.bitcoinplus.com/generate?for=1662848
Or you can just go to http://www.bitcoinplus.com - sign up and try to generate some bitcoins for yourself.
(actually you can have two pages up - one generating for a friend & your own. Then shrink them down and go on doing whatever as normal.)
It won't slow down a computer as it only uses non-active cpu processing. If you start up a game or go surf the web, it reduces access - it's a background runner. Sorta like the antivirus & similar programs that run in the background of a computer.
Either way I thought this may be interesting to look into.
