I think we should paint it this colour:
They had uncovered what seemed to be the side of a large coloured
globule embedded in the substance. The colour, which resembled some
of the bands in the meteor's strange spectrum, was almost impossible
to describe; and it was only by analogy that they called it colour
at all. Its texture was glossy, and upon tapping it appeared to
promise both brittle ness and hollowness. One of the professors gave
it a smart blow with a hammer, and it burst with a nervous little
pop. Nothing was emitted, and all trace of the thing vanished with
the puncturing. It left behind a hollow spherical space about three
inches across, and all thought it probable that others would be
discovered as the enclosing substance wasted away.
I think it really gets to the core of my feelings about this naming
discussion.

WOW! AWESOME KICK-ASS PICS!
Come to think of it, I could have called it "incognito addresses" - a
term nice enough that Google and Firefox use it in their browsers - but
what's done is done and any further discussion about this is just going
to confuse the public. Remember that in the long run all this stuff will
be hidden behind payment protocols anyway, and users *won't even know*
that under the hood a stealth address is being used, making the name
just a technical detail. For now though, lets use the good PR and get
some early adopters on board.
However, the term 'incognito' probably would be a good one to use within
wallet software itself to describe what it's doing when the user clicks
the "I want my transactions to be private" setting - there are after all
fundemental bandwidth-privacy trade-offs in the threat model supposed by
both prefix and bloom filters. In this instance the term isn't going to
go away.
Anyway, back to work: For the actual address format I strongly think we
need to ensure that it can be upgrading in a backwards compatible way.
This means we have to be able to add new fields - for instance if
Gregory's ideas for different ways of doing the SPV-bait came to
fruition. Given that "addresses" aren't something that should stay
user-visible forever, thoughts on just making the actual data a protocol
buffers object?
Second question: Any performance figures yet on how efficient scanning
the blockchain for matching transactions actually is? I'd like to get an
idea soon for both desktop and smartphone wallets so we can figure out
what kind of trade-offs users might be forced into in terms of prefix
length.
