To me, this feedback is the invaluable missing link that
all the third-party trust and shared-trust schemes I've
seen lack. When fred maintains his own trust keyring,
both fred and the bank know where the spammer got the
trust token. Also, both of them know the other will know
where the spammer got the trust token. A spammer getting
the trust token fred gave the bank will cost the bank
money, customer goodwill, and potentially business. And
fred and the bank must have contact with each other about
it if there is still a mutual wish to reestablish email
communication.

Machines suborned by spammers would be detected instantly
because all the trust tokens would be revoked within minutes
of the spammer using them. Spammers could not share trust
tokens around to get thousands of spam delivered on each
one, because fred would revoke the token the first time he
got spam on it and all the other spam would disappear. This
would destroy spammers' motive to cooperate by selling each
other spamlists. And when fred did revoke a key, none of
his legitimate email still arriving under non-compromised
tokens would be affected. Literally *EVERY* piece of spam
would be evidence of an information security breach traceable
to a single entity that fred gave his address to, and every
time spam were recieved there would be a single action that
fred could take to stop getting spam derived from that
particular information security breach.

This is basic digital signatures; it would work. We know
how to do it. We've known how to do it for a long time.
People would need to add one field to their email information
to keep trust tokens. Everything else you could implement
in the Mail User Agents. My inner cynic says nobody's
implemented it because nobody can figure a way to make money
by selling trust when users manage their own keyrings rather
than paying a third party to manage keyrings for them. Can
anybody else think of a better reason, or are we really
just lazy greedy bums who can't be bothered to work on
something unless we can "make money fast" doing it?

I'll try and hurry up and release the sourcecode as soon as possible to serve as a reference to help clear up all these implementation questions.

Cryptography DSL.
Lifted from a press release issued back in 2008.

Cryptol is a domain specific language for the design,
implementation and verification of cryptographic algorithms,
developed over the past decade by Galois for the United States
National Security Agency. It has been used successfully in a
number of projects, and is also in use at Rockwell Collins, Inc.

Domain-specific languages (DSLs) allow subject-matter experts to
design solutions in using familiar concepts and
constructs. Cryptol, as a DSL, allows domain experts in
cryptography to design and implement cryptographic algorithms
with a high degree of assurance in the correctness of their
design, and at the same time, producing a high performance
implementation of their algorithms.

Note: I am not in any way affiliated with Galois inc, and not, myself, a user of the Cryptol language. I'm posting it because I thought LtU might find this an interesting thing to discuss.

Numbers and how to represent them.

“Both Satoshi and I objected that [Bitcoin] wouldn't scale at 1MB. Hal was concerned about a potential DoS attack though, and after discussion, Satoshi agreed... But all 3 of us agreed that 1MB had to be temporary because it would never scale.”
