Alan Greenspan: It’s a bubble. It has to have intrinsic value: you have to

really stretch your imagination to infer what the intrinsic value of Bitcoin is.

I haven’t been able to do it. Maybe somebody else can. I do not understand

where the backing of Bitcoin is comingfrom

Private Monies

A widely accepted medium of exchange orpayment

issued by a non-governmental body

without legal privileges

Private monies do not have to be generally acceptable; they merely

have to be widely accepted

Public demand for private currencies:

hold them in the expectation that they will not diminish in purchasing

power as state money has

conduct illegal activity

wish tobe part of a movement against increasing state control of economic

and personal behavior

just want better money

Specifically designed to function in parallel with and in competition to USD

Never marketed or represented as official UScurrency

Highly successful: it became the second most popular currency in the US

Theannouncement

From: Satoshi Nakamoto <satoshi <at> vistomail.com> Subject: Bitcoin P2P e-cash paperNewsgroups: gmane.comp.encryption.general

Date: 2008-10-31 18:10:00 GMT

I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party.

The paper is available at:

http://www.bitcoin.org/bitcoin.pdf

The main properties:

Double-spending is prevented with a peer-to-peer network. No mint or other trusted parties.Participants can be anonymous.New coins are made from Hashcash style proof-of-work.The proof-of-work for new coin generation also powers the

network to prevent double-spending.

Nakamoto's political motivations

"Yes, [we will not find a solution to political problems in

cryptography,] but we can win a major battle in the arms race and

gain a new territory of freedom forseveral years. Governments are

good at cutting off the heads of a centrally controlled networks like

Napster, but pure P2P networks like Gnutella and Tor seem to be

holding their own."

"[Bitcoin is] very attractive to the libertarian viewpoint if we can

explain it properly. I'm better with code than with words though."

In the Bitcoin's transaction database, the first entry has a note by

Nakamoto: "The Times 03/Jan/2009 Chancellor on brink ofsecond

bailout for banks"

Source Code License

Bitcoin was released under the MIT license, so it is:

open source; cryptographic software’s source code must be availableto

allows public inspection (absence of backdoor and security

vulnerabilities)

free software; the user the right to use, copy,modify, and redistribute

the software

Instead, proprietary software is often close source and itonly grants the

right to use

Transaction: amount + receiver’s public key

The sender’s private key signs the transaction

With sender’s public key anyone can verify that:

The private key has been used, non-forged signature

Transaction has not been tampered ormodified

The amount is at sender’s public keydisposal

The transaction is published to the publicledger

Everybody knows that the receiver’s public key has receivedthe

Bitcoin’s public ledger: the block chain

Transactions are bundled in blocks, sequentially chained, about

one block every 10minutes

The block chain is a history of transactions resilient to network

attackers

The cryptographic link between blocks requires large amount of

computing power, so the block chain cannot be altered without

huge resources

Computing power is measured in hash/s, hash being thebasic

operation needed for validation

Mining

Miners are the nodes of the network providing the computing power

for:

processing and validating transactions (avoiding doublespending)

securing the network

synchronizing the nodes

Miners compete to process a new block of transactions. Thewinner

provides a proof-of-work and is rewarded with the issue of new

bitcoins.

Seigniorage revenues subsidize the network, making transaction

almost free

Friedrich August von Hayek -

Denationalisation of Money

history of coinage is an almost uninterrupted story of debasements;

history is largely a history of inflation engineered by governments for

their gain

why government monopoly of the provision of money is regarded as

indispensable? It deprived public of the opportunity todiscover and use

a better reliable money

Blessed will be the day when it will no longer be from the benevolenceof

the government that we expect good money but from the regard of the

banks for their own interest

A Free-Market Monetary System, Gold and Monetary Conference, New Orleans, Nov. 1977, https://mises.org/daily/3204

IMF’s SDR, F.Saccomanni

Special Drawing Rights are international reserve assets, created in 1969 to

supplement existing official reserves of member countries

SDRs address the lack of a non-national currency to be used as reserve

asset

F. Saccomanni: cryptocurrencies could be an effective monetary policy

instruments [...] we should pay more attention to the geniuses working on

them, try to understand what of interest they could teach us

Hard to regulate

Janet Yellen (Feb 2014 US Senate Banking Committee):

Bitcoin is a payment innovation that's taking place outside the banking

industry

It's not so easy to regulate Bitcoin because there's no central issueror

network operator. This is a decentralized, global [entity]

ECB (October 2012report):

governments and central banks would face serious difficulties if they

tried tocontrol or ban any virtual currency scheme

there is no server that could be shut down if the authorities deemed it

necessary

Benjamin M. Lawsky - NY DFSsuperintendent

The challenge we face is to come up withappropriate guardrails that safeguard customer assets;

protect consumers from fraud andabuse;

root out money laundering and other illicitactivities; defend against hackers by emphasizing robust cyber security

not stifling beneficial innovation in a fledglingindustry

In an age of heightened consumer expectations for real-time,digital

payments, if banks fail toinnovate, they could face a real challenge

Enough is enough: four decades of slow-to-non-existent progress inthe

bank payments system seems like fair warning

Massively Simplify Banking

I believe that blockchain technology will not only change the way we do

paymentsbut it will change the whole tradingand settlement topic. It has

potential to trigger “massive” simplification of banking processes and cost

structure. When somebody with a strong brand and security level

establishes it asa reliable service, then the whole industry will follow.

Oliver Bussmann, CIO of Swiss bankUBShttp://blogs.wsj.com/digits/2014/10/27/ubs-cio-blockchain-technology-can-massively-simplify-banking/

Major banks like JPMorgan Chase, Citibank and Bank of Americahave

established teams of experts focusing exclusively on digitalcurrency
