How does it work

I want to know how this blackphone thing works. It's a good marketing ploy, though, but is it just snakeoil?

This is an abolutely necessary feature as now smartphones have all the identitiies of the user and almost all private data is in there and many apps take all the permissions to use them before installation. Although it may not be completely possible to block these apps asking for permission but snooping can be definitely blocked.

I'm also wondering if blocking snooping adds any complexity to the code and if so, what do you think it would be? What are the compromises developers of such phones have to make? Or is it just the consumer that may compromise to protect his or her data from non-governmental snooping? (Who knows if you can protect your data from government snoops.)

It may look so. German agency and Angela Merkel also thought so. But when NSA and other gets invovled, they decipher the required information and get your information.

Also if you use these devices, they may pursue you more.

One would be naive to assume that the NAS/FBI/CIA wouldn't pay the company a visit  and insist on a "back door" for national security.

Agreed. It will be interesting to see how the company deals with the NSA or other government security agency and what guarantees of privacy it can make to the customer. The Blackphone may end up with an asterisk and fine print on its marketing claims.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
