blockchain

[Mike Kerner]

This isn't about connectivity.  This is about surviving a catastrophic
failure at a central authoritative data source, by eliminating the need for
a central data source.  Blockchains are not used to distribute data.
Blockchains are, in effect, streams of timestamped checksums.  Embedded in
them are all the other timestamped checksums for the chain.  Therefore,
blockchains enable you to determine who has the most current data (or, who
has the most recent copy of some piece of it).

-- 
On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
