Question
What is exactly the system to build? Answer
Digital cash
In 1998 life was very different
Internet was big already and needed payment tools
Internet bubble was coming
Credit card on line? Worked, but ugly
Internet banking was very unclear
Privacy was a huge concern on personal and even state level
No 9/11, no Patriot Act, no KYC, no FATF, anonymous accounts in Switzerland, offshore banking
Digicash
David Chaum “ Security Without Identification: Transaction Systems to Make Big Brother Obsolete ”
Digital cash
Absolutely new approach to remote payments with no accounts
.
Digital bearer certificate valued in a currency, digitally signed, by an Issuer (Bank), like a bill of exchange or a traveler check
low infrastructure cost (PC + Internet based)
highest security: strong crypto
Digital coins DBC #1234678988 Nomination: $123.25 Underwritten: Tavrichesky Bank Date:12.1.98 11:01 Digital Signature: 12345467575643434556563452678999
Blind signing: Bank does not know which specifically coin it signs, but knows face value. No trace of future spending.
Everything is signed, easy check by independent party.
No need in array of accounts support
Fast, private, save, elegant, new.
Digicash
Made up in Netherlands by Dr. Chaum
Deutsche Bank pilot
EU Technology Innovations Award 1995
Negotiation with Microsoft
One country, one Bank
Huge license cost
PayCash. Better Digicash.
Bypass patent umbrella
Multicurrency
Multibank
Even less trust needed
Smaller database
… .
We have done this… Chaum’s Coin( i , X ) = { i , X , g i -1 ( f ( X ))} , where X is the random serial number of a coin, chosen by a customer, X belongs to a large set M' M = (Z/ m Z) * , m is a composite number whose factorization is known only to the bank, f : M' —> M is an easy-to-calculate mapping publicly known and hard-to-invert for all parties of the payment system except, possibly, for the bank PayBook ( N , P ) = { N , P , g - N ( f ( P ))} , where P is User’s random public key , f , and g have the same meaning as above, and g - N ( X ) = g -1 ( g -1 (... g -1 ( X )...)) . A nonnegative integer N (the disposition of the book) determines paying capacity of the book.
… and even more New two-stage scratch card protocol Password Verifier Patent: Method for a cardholder to request fulfilment of an obligation associated with the card and for the issuer to acknowledge this obligation
Some IT
Thin server
Very thick client
Very secure environment, but proprietary and not easy-to-learn (for customers and shops)

Running the system
Development is slow
Cash burns fast
IT/Marketing interface is poor
… ..
Anyway, we are doing a great thing
2001. Outside
Digicash bankruptcy
9/11. Shift to conservative models
No more privacy motivation
Internet bubble exploded
Not a best time for private internet payment systems
2001. Inside
System became evidently commercial
No more privacy, but engine works excellent
Can be transformed into account-based model
We were getting Central Bank License
We became interesting for vendors, partners, licensees, etc.
We started join venture Yandex.Money
Yandex.ru is a biggest Russian search-centered portal (now in World Top 10).
Instant acquirement of a huge auditorium.
Sold in 2007 to Yandex Now 3+ mln accounts, $800 mln per year
What more?
To clone PayCash internet payments in another countries
