In this p
, a brief overview of the history of money will be given and principles of what make
money useful in business commerce. Then, categories with electronic money will be descr
and bring a distinction with electronic payment systems. Next, the impact electronic money has
had in general in our globalized economy will be discussed. Then, opportunities that computer
science has involved in the field of electronic money will b
e discussed such as in data security,
privacy, and traceability. In addition, drawbacks and risks involved in the use of electronic
money will be discussed. Finally, a summary will be made about the future expectations for
electronic money in the global
market place.


What is money or currency?

Beginning our discussion on electronic money, it will be helpful to first start with a short review
of the history of the development of money before describing the forms of electronic money a
their impact on our society and application of computer science in this field. There are important
principles to realize from the history of money as new electronic currency systems are going
back to older concepts of money
. Previously, currencies wer

backed by p
recious metals and
free banking was widespread
where private banks issued the
ir own currencies.

An appreciation
of the past will aid our understanding of the present and forewarn us of

in the future.

Early Moneys


history, humanity

has engaged in commercial trade through simple barter
and social gift
debt obligations, such as I
you arrangements. Although negotiation and
social expectations are not simple activities, these exchanges lacked any direct in
termediary that
we would call money that would facilitate the ease of exchange. The difficulty of matching
people with surplus goods and services available with those who needed or desired them and
could make an agreeable exchange was evident very early i
n our history. Early forms of money
were items that acted as intermediaries of exchange that were generally acceptable forms of
payment. These early forms of money were mostly commodity items such as rice,
, and
precious metals. The principle f
unction of the intermediaries was to store the value of the


original items being exchanged until the person could find another person to exchange the money
for the desired goods or services.

Minted coins became even more useful in facilitating trade
as standardized units of the
commodity metal used for money. The Code of Hammurabi
, which was one of the first written
legal codes,

was instrumental in positioning coined money into center stage of civilization
. The
legal code gave more security to the c
ommunity by specify the moral requirements and the

for breaking them. This inhibited arbitrary judgments by the ruling authorities.
These also contained specific laws

enacted for compensation by money for breaking of laws,
fines and fees
to b

collected, and defined
how much
interest was given for debts.
This set
standards of expectations on payment of debt as the receiving party had to accept the payment in
the authorized currency and could not require payment in another form.


Thus for

certain moneys to be functional they needed to possess three major qualities. First
principle is that the money token had to be a
nit of

such that it had a defined empirical
measurement like the weight of a metal coin, volume of rice, or size of

seashell. Secondly, the
money token needed to be an accepted
medium of exchange

in the community or political region
such that a person could take their money tokens and exchange them with anyone who had their
desired goods or services available for sale
. Third, the money tokens needed to be able to be a
store of value

such that they were not easily perishable and in the case of commodity tokens had
their own perceived value, such as with the content of gold and silver coins as precious metals.
These pr
inciples of money tokens are essential to the making commercial trade easy and help
economic growth.

Beginning Paper Fiat Money

ing the middle ages in Europe, t
ills started to be used as a statement of certificate of
credit for productio
n commodities to be delivered to the seller at a later point in time. This was
much like a personal lo
an to a small business. These t
ills began to be traded at discount
and face value and could be redeemed at local merchant banks. The convenience
of carrying a
few certificates instead of a large amount of coins or precious metals became attractive for
traveling merchants. This lead into the popularized of goldsmiths creating the first paper notes
as certificates of deposit o
r receipts for the gold

entrusted f

storage that were payable on
demand. This also developed into customers using these as promissory notes to the goldsmiths
who could use the gold on hand for advances to other customers or to fund their own work. With
public trust and stabl
e deposits, risks were low and so the goldsmiths became predecessors to the
modern banks with new credit based paper money. These early private merchant banks were
ng money or banknotes
by issuing loans
from the deposits held in reserve
. The securi
ty of
this representative money was it could be easily redeemed for either gold or silver deposits that
could be considered legal tender to pay debts. National governments caught on and began
to issue paper notes that could be redeemed for actual gol
d or silver that represented
. [3]

Fiat Money:



ds the end of the ninth century

as paper currency issuance and circulation expanded, gold
was no longer converted for paper money within

as deposits became small fractional
presentations of the currency in circulation and only used for foreign transactions. However,
during World War 1, England was forced to no longer use gold in foreign currency transactions
due to scarcity and so many countries followed the example. The go
ld standard was abandoned
in the Great Depression as governments allowed their currencies to float in value according to
market demands and central bank fiscal actions. Thus, currencies were no longer backed by
reserves of precious metals or other commodi
ty, but had a stored value by the fiat or decree of
the national governments to be legal tender. Fiat money is only backed by the ability of the
issuer or government to repay their debts and thus susceptible to public distrust and avoidance in
cases of un
controlled inflation or deflation.

What is electronic currency?


The term electronic money has several widely inclusive usages. Broad views of electronic
money include both online and electronic token representative value holders as

well as
authorizations of payments transmitted electronically. Such that both online purchases with
credit or debit card accounts and currencies such as Facebook Gold, Digital Gold Currency, or
other gaming currencies as well as private script or certifi
cates of deposit would be included.

In a narrower view, electronic money is those moneys or tokens of exchange that are only
transacted electronically. This would exclude currencies and payments that have physical
representation as in US Dollars, EU Eu
ros, and Japa
nese Yen.
The narrower view of electronic
money is preferred for distinction from national gov
ernment issued fiat currencies.

discussion will be made for the benefits of electronic only base moneys over credit/debit account
transfers i
n respect to online e


Types of Electronic Money

Community and Private Currency

As discussed earlier, some business such as a few private banks continue to issue their own form
of currency in contrast to government central banks.

hese are

mostly backed by precious

or other currencies held in reserve.

Private bank currency

can take the form of paper
notes, debit cards, and form
al electronic only tokens. These bank currencies


much more
regulated now than in the days of f
ree banking in the United States in the early ninth century.
Private and Free banks are required to collect taxes and have their currencies fully convertible
back into US dollars. The primary feature of these forms of electronic money is that they have
cceptability only in a very limited geographic area. The current movement to support local


businesses in areas in response to globalization has been aided by community currencies, where
local businesses will give discounts for payment in that local money.

Ithaca, New York has a local currency Hours which is Fiat with a pegged exchange rate of 1
Hour = $10 USD as a perceived measure of hourly wage. The Hour has the slogan “In Ithaca
We Trust” emphasizing the desire the build their local economy being in
operation since 1994

. Likewise, Berkshire Massachusetts also has a local currency called the BerkShare in which
local businesses off a five percent discount on purchases for using it


Hong Kong has
implemented an Octopus Card as a local currenc
y debt card to facilitate easier banking where
deposits are held at central banks of that providence

. Additionally, Toronto Ontario

own local dollar currency
. Instead of offering a consumer discount, the Toronto Dollar
Community Project
ects ten percent of sales for donations to non
profit community
organizations such as homeless shelters, women and children health programs, and food pantries

These local banking systems are opportunities for computer science professionals to use
talents to promote efficiency, transparency, and economic development.
Programmers have the
opportunity to increase efficiency in point of sale registers in communicating the transaction to
the financial network in a quick
and reliable amount of
e. By decreasing the time required to
checkout, customer experience greater satisfaction with the vendor. Programmers can also help
improve transparency in financial reporting by the local businesses that promotes greater public
trust that funds are not
being siphoned to fund
corporate investment or expansion
projects in
other parts of the world. Thirdly,

participation in developing local banking can
help in growing the local economy by promoting more local startup companies as the increased

income from the local bank can be used for capital investment.


Private currency can have significant risks in the long term stability and management. The
Liberty Dollar was produced in Idaho issuing warehouse receipts for gold and silver that cou
be redeemed on demand.

in 2007, the Federal Bureau of Investigation and Secret
Service raided the facility, which lead to charges being filed in May 2009 and the shutdown of
the currency in July 2009. The co
founder was found guilty on severa
l charges including
producing counterfeit coins in March 2011.


Hard and Soft Currencies

Soft electronic currencies are those that allow for payment disputes for fraud with the
transactions reversed. Credit cards use this as a major lure to cus
tomers promoting that their
customers do not have to worry about their cards being stolen. PayPal also allows for reversed
payments with a clearing or float time from three
five or five
seven business days.
Additionally, some hard electronic curren
cies can be softer when using a third party escrow

Hard electronic currencies do not have disputation services such that transactions are not
reversible in order to simplify the system and reduce operating cost from not needing to resolve

If your account information was stolen and fraudulent transactions were made, then no
form of restitution is possible.

However, i
n this type of
hard currency
system, the payments are


transmitted faster

automatic clearing of the bank so that
the funds are instantly available to the
receiving party.
Conversely, sellers have to wait to receive payment while the transaction is
cleared through a central bank with soft currencies.
Thus, the costs of making transactions to
both the seller and buye
r are greatly reduced, even though some risks increase.


Hard Currencies c

also be
somewhat soften by using a third
party escrow services. An
escrow service would guarantee payment at the time of the transaction is made. Once the goods
or servi
ces are delivered upon, then the payment would be sent to the seller. This does add an
extra cost to the buyer, but is a form of insurance that what was purchased is delivered.

World Currency

The most efficient currencies are those
that do not need e


for another currency

the desire to have one universally accepted currency for international trade is a large

international businesses to reduce the risk of losing value during currency exchange

Before World

War II
, the British Pound Sterling had the greatest dominance as the
world reference currency. After World War 2, the US Dollar held dominance and the US
economy was the least negatively affected by the war of major super
power nations. With the
ction of the European Union’s Euro currency, the US Dollar’s dominance has been
eroding as fewer nations peg their money to the value of the US Dollar. In effort to smooth trade
relation issues from currency exchange rate fluctuations, proposals are being

made for a single
new currency from the United Nations that would be balanced or pegged according to weighting
of the US Dollar, British Pound, EU Euro, and Japanese Yen. Broad acceptability is still an
issue in these efforts, but this would greatly incr
ease innovations in electronic currency and
electronic payment systems bein
g more standardized globally.

The Internal Monetary Fund [IMF] also has Special Drawing Rights (SDRs) that allow it to
withdraw reserves from central banks of UN participati
ng countries in order to receive payments
from debts. Some people advocate for a supra
national currency similar to SDRs to provide
more balance in international trade
, SDRs would still need to deal with exchange
rates of national currency a
s so would not make an ideal world currency. An electronic only
currency, independent of national currencies, would be more suitable for a world trade currency
in that transactions could be made efficiently and reduce exchange rate risk.

Electronic Curr
ency Example


is a recent entry into the electronic currency market. It is based on an open
source peer
peer payment network. Bitcoin’s main difference from other electronic currencies is that it is
decentralized from a central bank or server
This means that users of the bitcoin system
make direct payments to each other using encrypted messages. Bitcoin is a hard currency in that
transactions that have been authenticated are final and non
Each user is responsible
for prot
ecting their account information. The source code of the bitcoin client was developed
and released as open
source by Satoshi Nakamoto in January 2009.




Installing t
he bitcoin client software or wallet

is the starting point for using bitcoins. The
is a combination of address book for recording other bitcoin users and a log file of transactions
that a person has made. The client software allows
each user

to request up to one hundred
addresses in order to send and receive

. The wa
llet itself is a simple ‘.dat’ text file,
but the client software provides a method to encrypt that file.
Users can also use e
website services to maintain their transactions and balances from a webserver in order to reduce
risk from losing their w
allet from a personal computer crashing, receiving viruses, or corrupting
of files.

Bitcoins are attainable through purchase at online currency exchanges
, such as the largest Mt
Gox [
As well, Dragon’s Tale MMO online casino offers


or exploring
their virtual world [www.dragons.tl]. A person can also earn bitcoins from joining a bitcoin
mining pool and allowing the mining program to run during idle time on the user’s personal

. There are multiple private mining pools in
the bitcoin network. Mining refers to
the running of problem solving algorithms
for about two to four months
that has variable

according to the number of other users currently mining and the amou
nt of bitcoins in
circulation [
]. So then, ther
e are several inherent cost in trying to mine bitcoins such as the
electricity used by your computer and the cost of the computer equipment, namely an advanced
graphics card so then your primary central processing unit chip is not bogged down by the

software and cooling equipment.
Consideration of the expected exchange rate and the
expenses incurred for the mining activity needs to be made by prospective users to determine
affordability of participating in a mining pool.

Bitcoin transactions are
sent public throughout the entire network using

public key
encryption in order to

ensure only the intended recipient can decrypt the send bitcoins
. The
privacy avowed is such that only the user’s wallet address is sent with the transaction without

any other personal identifiable information. Additionally, a person’s wallet address
can only be
individually identified by

their network card adapter’s serial number, which can help to prevent
identity theft

as bank account or personal information is no
t used in clearing transactions
. The
recent case

of account theft has been from the compromise of the security of e
wallet services.
The bitcoin transactions are confirmed through block chaining
such that the network keeps a
history of all attempted tra
nsactions and can re
ject attempts to reuse bitcoins


From reading
the source code for bitcoin wallet client [www.github.com/bitcoin/bitcoin], use of mutex
semaphores are evident to enforce mutual exclusion in the recording of sent and received

What issues surround electronic currency?

Data Security is a huge issue protecting and encrypting bank accounts and transaction records for
both traditional banking with physical currencies

s well

electronic currencies have more
lity to

across the internet for personal information

being intercepted or
account passwords being broken
Password strength and protection is an issued shared between
consumers and merchants. Consumers are responsible for selection passwords tha
t are not easily
figured out and not sharing it. Merchants are responsible for maintaining their files securely.


Additionally, use of SHA
256 hash encryption can greatly ensure less

missions from being decoded

by illegitimate par


Duplication Fraud is another major topic with electronic token currencies and why some are
strictly hard currency with no payment dispute resolution so as to not allow already used digital
currency certificates to be used more than once
. Bitcoin


prevents this upfront as
transactions are not completed until six blocks are received confirming the currency was not used
in a previous transaction in the database of all transactions. Electronic or Automatic Clearing
Houses (ACH) are used by so
fter currency payment systems to check that the available funds are

and accurate also

that the parties are authentic users of the system [2].

Identity Theft is another issue and balancing act for how much of a customer’s information
should be

shared in electronic transactions as more electronic currencies agencies are pushing for
anonymity to protect their clients

. However, allegations are not without some merit that
completely anonymous currency transactions would easier money laundering

and funding of
illicit drugs, gangs, and terrorists


Consumers assume risks

of using electronic wallet

as well as how they protect their passwords and other personal data

Traceability and Privacy are also balancing points. Customers often

desire to be able to keep
purchasing records in one place. Law Enforcement also wants to have the ability to track down
criminal activity

. However, not all customers want their even basic information or
purchasing trends made available as we alread
y get enough junk mail and email sent to us.

principle concern by United States financial regulators is to be able to catch those who engage in
money laundering by tracking their activities over time. This goal is accomplished by stopping
single tran
sactions, but developing cases against organized crime [1]. However, financial
institutions also desire to minimize the amount of information stored containing customer’s
personal information that could be used in identity theft reducing their liability r
isk for the data
they must protect [4].

What is the future of electronic currencies?

There are several electronic currencies aimed to being Complementary or Parallel National
Currencies in the effort to become trans
national in the global market pro
viding cheaper
processing and easier international exchange.
Convenience is the major hurdle for private
currencies for consumers to adopt using their money and services. Convenience is also a main
need for merchants to provide quick customer service in
payment transaction [9]. Electronic
currencies do provide much quick

confirmation and
dispute resolution from
having a
traceable history
. It would be inconceivable going back to paper & coin money from the
convenience and cost effectiveness of
electronic money and payment systems [16]
. Financial
institutions that make their profit on the margins of transactions will always be looking for ways
reduce costs. It will take a long time for pure electronic currencies to gain widespread
ity, but it will continue to grow as benefits are realized from transitioning away from
paper money.



The basic expectation for regulation is that no new policies or laws will be issued in the future.
Some advocates would say that enough laws are already
on the books from the advent of credit
cards for transactions in the United States. However, there is a mix of regulations for foreign
transactions which likely continue to be difficult to sort through in the larger perspective

Currency and

systems that shield the location and identity of users will remain popular
among individuals as distrust of governmental financial institutions never goes away. Peer
Peer networks seem to be the best option for private currencies to reduce the opportun
ity for
government interference.

Smart cards, those with value / currency information stored directly on them, seem to show the
most near future growth potential [1]. Consumers are mostly familiar and accepted use of credit
cards so it is not a far jum
p to using smart cards. These cards are limited from holding much
consumer information and so not posing much threat in the area of identity theft. The cards can
be used offline
by reader devices and are becoming more cost efficient for merchants. Advan
have been made to use cellular or smart phones as shored value cards that would be either linked
to an account or stored value such as a debit card. Already smart card chips can be placed in
cellular phone cases for consumer convenience [16]. Some sp
eculation has been made that cell
phone minutes would be a commodity for electronic payment transaction, however, cellular
phone service providers are turbulent and highly competitive reducing the chance of widespread


The glo
bal banking industry is becoming a new frontier for computer science.

As necessity is
the mother of most innovation, electronic money will continue to be a solid driving force for
programmers to develop stronger encryption methods for secure data transmis
sion. As our
American culture is moving away from carrying physical cash, business will continue to
innovate in the area of electronic money and payment to attach customers by convenience while
attempting to reduce costs for greater profits. Online anony
mity will continue to be a priced
value for consumers online as private banking systems will use it as an appeal to electronic
money from other credit card services providers. With the major developments in the integration
of the global marketplace, commu
ity electronic currencies

provide an affordable venue for local
community development.

Thus, programmers have more options that only employment with
large corporations in the financial field. Electronic payment systems are not fading into the
future but

are replacing paper currency. Electronic currencies are new in respect to computer
technology, but are a return to the basic fundamental principles of money.
