Seems decent, except for the "public key cryptography 101" box: analogy with a pair of keys is confusing and wrong. My favorite explanation is the one I stumbled upon on this forum (not sure if Netrin came up with it or he adopted it) -
Yeah. Here's a magical analogy for public key cryptography: I generate a private key and numerous public unlocked treasure chests. I give these open treasure chests to all of my friends (it's easy to copy them). Whenever a friend wants to send me a message, they just put the message in my public treasure chest and close the lid. Now even they can not open it again. Only I, with my unique private key, can open the chest.
After I generated the public keys, I don't really need them any more, unless I want to send messages to myself. But no one needs the private key to lock a message. The private key is only required to open a message.

Relatedly, this is the coolest bitcoin infographic I've seen: I really like this as well. Look forward to infographics like these and more in the Bitcoin Magazine in the future. We were a bit too busy last month to include more than 2 into the first issue. I agree with our marketing lead Mihai Alisie that they are crucial for bringing new blood.

Love it. My guess is that Post #3 will be addressed and Matthew will have this as the centerfold in some upcoming issue of Bitcoin Magazine. ~Bruno~ |

I used to love reading Spectrum when I was a young EE/CS student. I also like the graphic.

I don't see anything that is technically incorrect about the PKI explanation in the graphic. Do you care to explain what is wrong with it? netrin's quote is cool for the noobs, but it doesn't mean that what is in the graphic is incorrect at all. Both quotes are very correct and explained differently. |

OK I can see the confusion then. |
