Permission to reproduce diagram I'd like to get permission to reproduce the diagram on how bitcoin works at What does a Bitcoin transaction consist of? for a book on money that I'm presently writing for Routledge Publishing. How would I do that or is the image free to be used?
Thanks!
As far as I understand the diagram was produced for IEEE Spectrum. They have a Reprints &amp; Permissions page that might help to get in touch with them on this matter.
