Let me help the general counsel of the Office of the Director of National Intelligence with the law

Reuters: But the general counsel of the Office of the Director of National Intelligence (ODNI), Robert Litt, said in an interview with Reuters on Tuesday that the legal interpretation needed to be adjusted because of technological changes.    "Computerized scanning of communications in the same way that your email service provider scans looking for viruses - that should not be considered a search requiring a warrant for Fourth Amendment purposes," said Litt. He said he is leaving his post on Dec. 31 as the end of President Barack Obama's administration nears.

The law that applies says that Yahoo may scan our text, we implicitly agreed to it.  But the public has no access to our data, so neither does the law without an acceptable warrant for seizure of said data.   In other words, if it is not publicly searchable, then get a warrant and show cause. .

Government is inherently conflicted.  They want cyber security to hide insiders but also want the technology to peek at will.  It is a problem for central bakers and for snoops.

Secure card has adopted a simple rule.  Smart card only does money, nothing else.  There is no reason for any human to peek. If the government wants certain data, then they can have a finite probability distribution of the current pit, There is no other information available.

Government has to talk to the smart contract folks, and leave price out of that discussion, its been paid.
