What is Bitcoin?
1. A currency without central control or identifiable issuer

computer science
Ownership secured by technology, not rule of law.
«Wir werden solange kein anständiges Geld
bekommen, bis es anderen frei steht, uns ein
besseres anzubieten als die jeweils herrschende
Regierung.»

Kommentar von «Wonko the Sane»
“The revolution already happened - it's called Bitcoin.
I've spent the last year bank-free.
I live in the US, but work for a Swiss software company and get paid
the CHF equivalent of $160k/year.
They pay me in Bitcoin. I have no bank account.
Everything I need to buy I either pay for directly in Bitcoin, or in cash.
When I need cash, I use LocalBitcoins to find somebody who wants
to trade.
The "massive bureaucracy with its bloated laws and indifferent
employees" can fuck off. They can point their guns at secp256k1 all
they want but it won't do them any good.
I just have to laugh at people who still care about or participate in
politics - it's a complete waste of time. Within a few years Bitcoin has
accomplished the change which many decades of voting have failed
to provide.” - Wonko the Sane, Slashdot.org, 2014-10-26

Must understand to use
No. Who knows how ECCards work?
No, but interesting.
Money supply
Controlled by central bank
Currently: 886 billion CHF
Pre-determined (more out of
technical necessity than for
ideological reasons).
Limit: 21 million BTC
Backed by
Nothing (in the past: gold)
Nothing
Virtual
92%, stored as number in
databases run by banks
(only 8% of M3 are coins or
notes and thus also legal
tender)
100%, stored as numbers in a
database run by an
anonymous collective
everyone can join

Distributed Ledger Technology (DLT)
Dezentral organisiertes Eigentumsregister
Keine Kontrollinstanz
Regeln nach Konvention
Open Source
Vollständige Transparenz: alle Regeln bekannt,
Geldmenge bis in alle Zukunft vorbestimmt, alle
Transaktionen öffentlich

Analogy
We determine:
 Everyon in the room gets 100 SIPUG-Coins
 Freely transferrably by loud announcement
 Everyone keeps track of everyone else’s balance
 In case you miss a transaction, ask a few
neighbors
 Every 10 minutes we agree on a bundle of
transactions by majority vote

21
Moving Online
 Identification by digital signature
 Voting weights proportional to computing
power (one of the few things that cannot be
faked online)
 Incentive for correct archival of transactions
(mining)

Soon also attracts banks?
Oliver Bussmann (CIO UBS) in WSJ.D on 2014-1017:
«I believe that blockchain technology will not only
change the way we do payments but it will change
the whole trading and settlement topic.”
«When somebody with a strong brand and
security level establishes it as a reliable service,
then the whole industry will follow.”

Future
 Smart, self-executing contracts
 Distributed autonomous organizations
 Decentralized autonomous companies
(Based in Zug,
18 MM USD funding)

32
Smart contract: Bet
 Alice and Bob bet 100 Ether that Brazil wins
against Germany in the world cup
 They program a contract, release it to the
Ethereum network and load it with 100 Ether
each
 As soon as the result appears on fifa.com, the
contrat is executed and 200 Ether sent to the
winner
Btw: no judge in the world can stop the execution
of the contract. It happens «in the cloud».

33
Distributed Autonomous Organizations
 What if a program outlives its creator and
continues to act economically?
 The program might buy and sell goods and pay
for the resources it needs to run
 Example 1: autonomous exchange for cryptoassets
 Example 2: autonomous trader on such
exchange
 In cryptofinance, you don’t know whether your
counterparty is human or machine

34
Scenario 2100
 Tainter: complexity of societies tend to
increase of the course of time
 Bureaucracies eventually collapse under own
weight (e.g. Roman empire)
 Bitcoin not backed by laws,
backed by technology.
 Provides reliable payment
system even in times of chaos.
