Transcript of the telephone conversation with
David Chaum of Digicash

"Tuet ... tuet ... tuet
David Chaum: Good morning, David Chaum.
Moving Art Studio: Hello, this is Jens-Ingo Brodesser from Moving Art
Studio in Brussels. Last year in June  we held an independent
meeting on the form and affects of electronic money. During this
meeting the Digicash's E-cash was described as being the most suitable
form of electronic cash - being both confidential and secure...
C Privacy protection, that's right.
M We've recently been hearing that Digicash is bankrupt, is this
C Yes, unfortunately that's true. There are different kinds of
bankruptcy. This one is a Chapter 11 Reorganization here in
California. Basically the assets are going to be sold. Someone will
probably buy them and carry on with the product. That seems to be
M How did this bankruptcy happen?
C [laughs] I can't really comment on that. You can look at our
website and draw your own conclusions.
M The system has been licensed to huge interest groups like Deutsche
Bank and Mark Twain Bank.
C Yes, I know. [laughs] The system is still alive in Switzerland
(Swiss Netpay from Credit Suisse) and Australia. If you look at the
Digicash website you can see all the places where it's operational.
You are just wondering how Digicash can be bankrupt while all these
people are using it.
M Now that the Digicash technology is no longer available to people
wanting to make secure and anonymous online transactions, the only
things remaining are insecure and unconfidential systems such as VISA
C At the moment, but I think that things will change.
M Do you think that there will be again an online payment system like
E-cash - a system that doesn't keep user profiles? There are some
smart card systems like the Geldkarte in Germany or La Carte Proton in
Belgium, but these route every transaction over hidden shadow accounts
where the users' expenses are tracked.
C They do? - I didn't know. Digicash is up for sale and I think
whomever buys it will continue to operate it.
M Here in Belgium for instance there is Proton, but the problem with
this kind of payment system is that everything you buy with it is
C And it's also that people assume that this is not taking place. The
way these products are often promoted to the public is that they are
essentially like cash.
M Yes. Also often the banks don't give any choice to the customers.
Here in Europe we have the EC-card which now has an EEPROM printed on
it. You are ready to use this system and think that it is a kind of
cash system but actually it's a credit card.
M So you are going to sell the patents and technology on which
Digicash is based to someone who will try to get it back into the
C That's correct.
M There's been no hostility towards Digicash from the national banks
fearing it will affect their monopoly? At first we thought that there
was a strong lobby that caused the Digicash project to fail.
C No, but one can never be sure about what really is going on in the
banking world. We haven't experienced any overt problems.
M The credit card companies also represent a strong lobby in this
market. Did they see your system as a threat?
C Hmm - [long pause] well - [long pause] - It differs. We tried to
ally ourselves with some of the credit card companies. Obviously there
are all kind of players in the field which can see us either as a
threat or an opportunity. [laughs] It just depends - and they could
also view it as too early to worry about.
M Do you think then that the Digicash technology entered the market
too early - that people aren't yet used to this kind of technology?
C There were things like that. Electronic commerce was hardly
happening at the consumer level when Digicash was trying to gain
momentum. The ease with which things could be integrated into the web
has improved a lot since we were most active. The technological
infrastructure was a little less optimal then for us than it is today
- as far as making it easy for consumers and merchants to use it. I
expect that it will get even easier.
M Are you thinking about SSL?
C Well, a whole lot of things - the way you can maintain and update
software over the net... just a whole lot of problems that we ran
into. When we started people were using all kinds of imperfect ways to
get access to the net. There was a lot more diversity and uncertainty
at that point. It was harder for the end user to make things work well
M Will there be an anonymous and secure electronic cash system soon,
or is there a general trend towards existing systems which just carry
the credit card principle on the net? As I said before, there is often
a strong interest in tracking the users' behaviour, knowing what they
are buying, where they are buying it and being also able to connect
this information to targeted advertisement.
C I think you have both kind of forces. The thing about the interest
in having consumer controlled privacy protection is that most people
(most consumers) aren't that aware of it, and it's not really a viable
option today, but I believe that it could dominate if it is both made
readily available in an easy to use manner and awareness of it is
created. Because there are also a lot of problems with abuses on the
net, you see what I am saying?
M In the Digicash system there are electronic coins issued. In the
past this has been, to a very large extent, a monopoly of the State
and the national banks.
C That's true, but look at all kinds of other payment systems. The
sacred distinction between money and just payment systems is fading.
There is online electronic payment in general and it is hard to say
whether or not it is really money. I think this is a non-issue. We
haven't received any problems about that. Just look at any kind of
technical system of this general online nature. Either, like the smart
card, or whatever, it's electronic money - the card is the money or
the data is the money, or you could look at this as a bill paying
system where actually the money is stored in the banking system. It's
just a matter of how you want to interpret - for the consumer it's
often nice to tell them that their card is the money - has the money
on it, but for the bank regulators you can say, well, the money is in
this pool account while these balance numbers are stored on the card.
It's more a matter of how you want to interpret the technical system
than there really being a clear distinction between an electronic form
of money itself compared to just an electronic banking system.
M And the banks like Deutsche Bank and Mark Twain Bank - did they
stop their Digicash services or are they still available?
C If you look at our website you will see that several services are
still alive, those particulars ones are not. Credit Suisse with Swiss
Netpay is and in Australia it's alive and I think that Bank Austria is
too, but they are not doing very much.
M Are these services offered just for local customers or can people
from all over the world apply for an E-cash Account?
C The Swiss one is more for Cr+dit Suisse customers but I believe
that the Australian one does allow you to pay with credit cards. At
least it was supposed to do so, I am not sure if it does at the
moment. But most of the places you can buy stuff are in Australia so
it's not that interesting outside of Australia.
M Why did Deutsche Bank stop their Digicash services?
C Actually I don't know.
M You didn't get any explanation?
C As I am only loosely affiliated with Digicash at this moment I am
sure that there are more people here at Digicash who know all the
details - I don't personally know.
M What are your plans for now? What are you working on?
C I'm working on some new stuff that's as much as I can say on that
at this moment.
M How do you perceive the future of digital money?
C I think that it will replace paper money eventually and will be a
dominant form of money. Digital cash as I've developed it is actually
better than paper money in the physical world because of the way it
solves the privacy problem and at the same time attenuates the
possibility for criminal use. It also has the advantage of being
visible in the physical world as well as in cyberspace. So, that gives
me confidence that it will replace paper money at some point.
M Thank you very much.
C Well thanks. I wish I could be more detailed in my answers, but
right now things are in a state where I can't be. I hope you
appreciate that. Perhaps we will have a chance to discuss things in
more detail, especially when things get rolling again."
