Satoshi’s PGP Keys Are Probably Backdated and Point to a Hoax
The latest claim to have found the pseudonymous creator(s) of Bitcoin, Satoshi Nakamoto, appears to be unraveling. One thing we do know for sure is that much of the work done to get Bitcoin to where it is today was actually done by Nakamoto’s successor (see “The Man Who Really Built Bitcoin”).

Why AT&T Is Out-Building Google Fiber

Companies on both sides say they have technical evidence backing up their claims.
