e$: What's a digital bearer bond?

It's the little questions which take the longest to answer...

I wrote something here in cypherpunks this year called "The Book Entry /
Certificate Distinction", which you might want to check out in the
archives.

Bearer bonds and bearer certificates (like cash) belong to the bearer. To
be flip, possession is 100% of the law with a bearer bond. Bearer bonds can
be stolen, but they aren't registered anywhere, which makes them useful for
anonymity. All along the bottom of a bearer bond are little squares called
coupons, which you cut out periodically and mail in to the issuer, and
they'll send you back an interest check for that period's interest. Lots of
financial phrases come from bearer bonds. When a bond trader talks about a
bond's interest rate, she may use the word "coupon" interchageably, as in,
"That bond has a 7% coupon.". Meaning, it pays 7% interest per year. Then
there's the phrase "clipping coupons", meaning someone is retired or
independently wealthy and living on their bond interest. Every month the
interest on one bond or other would come due, the coupons clipped and sent
in to the bond's issuer in return for an interest check.

Most securities these days are registered to the owner somewhere, at a
trustee, at the issuer, at a clearinghouse, or some combination of all. In
fact, most securities these days don't exist in physical form at all and
exist only on the books at clearinghouses and brokerages. This is why your
stock broker squalls about "physical delivery" when you ask for a
certificate. About a year ago, we talked about the Depository Trust
Company, the clearing house for the New York Stock Exchange. They have
entire issues there consisting of a single piece of paper in the
clearinghouse vault which are traded entirely on a book entry basis, that
is, only accounting entries are swapped when these securities change hands.

There are several reasons for this. The putative reason is that as taxing
authorities, like the Internal Revenue Service, have relied increasingly on
various cash-flow taxes like the income tax for thier revenue, they have
slowly regulated or legislated bearer bonds out of existence in favor of
registered, and more to the point, book-entry securities.

However, like everything else, law and regulation is really a creature of
technology, and the technological reason that book-entry and consequently
registered certificates are popular is because they're cheaper to handle
locked down in a vault in a clearing house somewhere with the ownership
changing hands by changing offsetting accounting entries at the buyer,
seller, and clearinghouse.

This is a direct consequence of financial systems organized on top of
hierarchical communications networks, which was how all communication
networks were organized before automated switching, and, more to the point,
microprocessor switching made them more and more geodesic in structure. You
might want to check the archives for more of my rants here on that subject.

The thing about digital certificates, of which ecash is only the camel's
nose in the tent, is that while electronic, they're actual bearer
certificates. You get a lot of great non-sequiters when you talk about
them. "Digital bearer certificates", when you can't actually touch them to
"hold" them, Electronic "physical" delivery, and the like.

So, with a digital bearer bond, you would have in effect a bundle of
digital certificates. One would be for the principal and whould be good for
the repayment of that principal on the date the bond was called or the
redemption date, however the bond offering is written. The other
certificates would represent coupons, one for each interest period for the
life of the bond.

These digital certificates, in combination increasingly geodesic networks
enabled by exponentially falling microprocessor prices and strong
cryptography, theoretically allow secure, point-to-point trading of any
security of any amount with instantaneous clearing and cash settlement.

The current hierarchical capital market model, with brokers, "wholesalers",
and central exchanges has been collapsing for decades since the advent of
electronic trading systems (glorified computer bulletin boards, really)
like NASDAQ.  With the coming of digital certificate technology on public
networks, these markets will be "surfacted" into smaller and smaller
concentrations of information and capital.

I have no idea what markets will look like when we "return" to things like
digital bearer bonds, but there's a prima facie example now on the web as
we speak. This week Mark Grant just upgraded his Electronic Cash Market
(ecm)-based cyberbuck (c$) webpage "trading post", so that it will take the
new Mark Twain ecash. That means that it will be possible to trade old
Digicash beta-certificate c$, which sold for 5 cents US per c$, and
instataneously clear and settle them for Mark Twian ecash on-line. No
checks have to be sent between trading parties to buy these certificates
anymore, which should lower transaction costs significantly, not to mention
the float on the money while the trade settled.

It was curious that people were buying these things to begin with, as they
had no value at all except their uniqueness, anonymous electronic
transmissibility, and a promise from Digicash BV to issue only a millon of
them.  Yet now, with the market made infinitely more liquid with the
introduction of real-time cash settlement, things will get, as Alice said,
"curioser and curiouser". Digicash still has some large number of these
things in the "treasury" unissued. I believe these original beta-test
certificates have both payee and payor anonymity, especially if traded
offline, which has been how they've been traded through the ecm.

More fun with numbers.

Cheers,
