Apropos of recent news stories about a blockchain based voting system
that was hacked before its first election, someone asked:
Perhaps final recognition that a lot of blockchain is hype? Or
simply an interesting side-story?
A blockchain can ensure that the lies you see are the same lies that
were published, but that doesn't have much to do with voting.
Voting has a very peculiar security model -- you need to verify that each
person voted at most once, you need to count all of the votes for each
candidate, and you need not to link the two. A lot of very bad voting
systems are built by people who wrongly assume that its security model
is similar to something else, which it is not.
An obvious example is Diebold who built voting machines that worked
like ATMs, which was a disaster, since the way you audit ATMs depends
on the details of each transaction being linked to the person doing
it.
Paper ballots have a lot to recommend them. It's easy for poll
workers to observe that each voter puts one ballot into the box,
they're relatively easy to count (we use mark sense machines here) and
compared to the spaghetti code in direct recording machines, they're
quite tamper resistant.

The IETF is in the midst of a vigorous debate about DNS over HTTP or DNS over HTTPS,
abbreviated as DoH. How did we get there, and where do we go from here?

I'm moving some of my financial accounts to Lively, a fintech startup.
We've had the usual chit-chat about details of where the money is coming
from on the messaging system on their web site. It works fine, when
there's something new they send me a note saying to log in and check
my messages.
Except that today they sent me a message through a third party "secure"
messaging service.
To protect the guilty, we'll call it Hubri.

I have recently become aware of
a blog post
from Recorded Future that
attempts to analyse the effects of the GDPR on online security.
Unfortunately, it starts by asking an irrelevant question, and then
goes on to use irrelevant metrics to come to a meaningless answer.
The premise of Recorded Future's article -- that spammers would send
more spam and register more domains because GDPR came into effect --
tells us nothing useful about how GDPR affects anything. It's the
wrong question, it's not a question most security people are concerned
with, and it ignores how spam and spammers work.

One of the chronic features of the Bitcoin landscape is that Bitcoin
exchanges screw up and fail, starting with Mt. Gox. There's nothing
conceptually very hard about running an exchange, so what's the problem?
