There is the option to publish

revised versions of the contributi
on in a

special issue of "F
u
ture Internet".

Starting point:
Bitcoin is a form of electronic money whose core properties root in stochastic
replication consistency. The algorithm is completely decentralized and operates in a p
eer
-
to
-
peer environment. As a project, Bitcoin is an Open Source activity with contributions accor
d-
ing to the crowd sourcing model.

The concept raises a number of challenging technical, economical, legal and architectural
issues, which combine questions fr
om the area of stochastic algorithms, replication co
n-
sistency, cryptography, data protection and security, privacy enhancement and network
analysis. The concept which is used in Bitcoin for electronic money may also be used for ot
h-
er decentralized, weakly
-
consistent, replicated registries, such as name services.

Bitcoin, the application of these ideas in the area of electronic money, realizes a cost effe
c-
tive and secure method for transferring monetary values, without the need for a trusted
central
institution. It is immune against attempts of political influence ("printing money"). In
the econo
mic and legal area there exist numerous questions with controversial answers.

The topic of Bitcoin being still very young, the first implementation w
as availa
ble in 2009.
T
he project is undergoing dynamic and rapid development. The
first European conference on
Bitcoin

was held in Prag in November 2011, hosting some 100 participants. In Berlin and
Mu
nich there are regular
meetings furthering the development and use of Bitcoin, where
you also can pay for your bar consumption in Bitcoin. Step by step Bitcoin is also adopted by
the academic community: The first survey and scientific articles are being written.

At the yearly co
nvention of the German Society of Informatics, a combination of a Tutorial
and a Workshop on Bitcoin will be held.

The half
-
day tutorial
will first provide in a series of coordinated talks an introduction to
Bitcoin and will address the challenging questio
ns


especially from the point of view of alg
o-
rithms, system security and application programming. We will deal with the following topics:



A Survey on Electronic Money



Cryptographic Primitives in Electronic Payment Systems



Introduction to the Block Chain A
lgorithm used in Bitcoin



Non
-
Bitcoin Applications of the Block Chain, such as NameCoin



Bitcoin in the Payment Process



Bitcoin Security and Anonymity



The Environmental Cost of Bitcoin



Future Bitcoin Research Questions


The half
-
day workshop

will then provide a forum for contributed publications.

Call for Papers:

We are soliciting contrib
utions of a maximum of 15 pages, preferably in En
g-
lish, of new, original and unpublished research results. The contributions will be blind
-
reviewed by at
least three members of the organizational committee. Submissions from the
organizational committee are welcome. Our target is an acceptance rate of 40 t
o 60%, a
c-
cepted papers are published in the Conference Proceedings of the yearly meeting of the GI.

The
criteria for selection are originality, innovation, choice of topic and quality of the prese
n-
tation. The contributions must be formatted accord
ing to th
e LNI
-
format available at
http://www.gi

Target Group:

The tutorial

addresses computer scientists and researchers near to computer
science and economy, who want to get a comprehensive introduction to Bitcoin or want to
enter the field with own research and developmen
t activities.

We attempt to prov
ide a life
video stream of the E
nglish spoken tutorial and will make the material available on an open
license basis afterwards.

The workshop
addresses the researcher and professional in the area of Bitcoin. The goal is to
c
ontinue the discussions of the recent meetings in
New York

and
Prag
. While the
preferred

language is English, the workshop will be open for German contributions as well.
