physical  presence,  while  others  have  completely 
transferred their activities to the web. 
Nevertheless, we are witnessing today yet another 
transformation  of  commerce. The advent of mobile 
technologies,  supported  by  the  great  availability  of 
wireless  networks  and  easy  to  use  handled  devices 
has given way for the rise of mobile commerce (m-
commerce).  This  type  of  activity  is  basically  “an 
important  step  towards  achieving  an  anywhere, 
anytime paradigm” since it is possible to buy and sell 
products and services at all times from all locations, 
i.e.,  these  two  dimensions  no  longer  constrain 
business activities (Maamar, 2003). 
Junglas  and  Watson  argue  that  these  two 
paradigms,  e-commerce  and  m-commerce,  exhibit 
some features, which differentiate them entirely from 
one another.  Specifically,  the authors  argue that m-
commerce  and  e-commerce  exhibits  significant 
differences  along  the  concepts  of  reachability, 
accessibility, localization and portability (Junglas and 
Watson, 2003). Indeed, while it may be said that both 
paradigms provide to a certain extent all of the above, 
the  former,  i.e.,  m-commerce,  subject  to  other 
variables  (e.g.,  network  availability)  manages  to 
provide  them  in  an  unrestricted  fashion,  without 
setting limits to e.g., reachability and portability. 
Following  m-commerce,  it  is  posited  that  yet 
another paradigm is about to emerge, that of ultimate 
commerce  (u-commerce)  (Junglas  and  Watson, 
2003). Weiser has introduced ubiquitous information 
systems in his seminal paper (Weiser, 1991). In it, he 
described  a  world  where  the  boundaries  between 
everyday  life  and  technology  blur  together  as 
information  systems  weave  themselves  into  our 
everyday activities. Based on this, Watson et al. have 
defined  u-commerce  as  “the  use  of  ubiquitous 
networks to  support  personalized  and  uninterrupted 
communications and transactions between a firm and 
its  various  stakeholders  to  provide  a  level  of  value 
over,  above,  and  beyond  traditional  commerce” 
(Watson et  al., 2002). In  other words, u-commerce, 
supported  by  ubiquitous  networks  and  universal 
devices,  will  help  commerce  become  independent 
from  space  and  time,  and  extend  itself  beyond  the 
traditional paradigms (Junglas and Watson, 2003). 
At the same time, beyond the transformations that 
commerce has been undergoing recently, businesses 
are  yet  again  faced  with  more changes.  It  has  been 
noted that the structure of a typical business has been 
changing  recently  as  well,  and  that  the  typical 
hierarchical structure has slowly but steadily shifted 
into a pancake design. These two examples, the 
pyramid and the pancake, occupy the two opposing 
extremes of a spectrum (Schneckenberg, 2009), while 
in  between  them  there  are  several  variations  and 
combinations  of  the  two.  To  elaborate  further,  the 
traditional pyramid reflects the “hierarchical culture, 
in which leadership makes centralized decisions at the 
top  of  the  organization  and  pushes  these  decisions 
vertically  down  to  lower-level  employees  for 
execution”  (Schneckenberg,  2009).  In  contrast,  the 
pancake  design  places  all  employees  on  the  same 
level, as they are rather autonomous and make their 
own  decisions,  drawing  from  their  experience  and 
expertise.  In  these  cases,  the  employees  do  not 
necessarily  need  the  authorization  of  central 
management,  but  they  can  rely  on  their  own 
judgment. 
These  changes  have  been  facilitated  by  two 
different  features.  First  of  all,  studies  reveal  that 
currently  there  is  a  shift  of  demand  from  goods  to 
services. Therefore,  contemporary  businesses  are  in 
need to deliver a service even in cases where they are 
in fact produce a specific  product  (Greefhorst  and 
Proper,  2011).  Secondly,  recent  advances  have 
allowed  the  decrease  of  costs  for  information  and 
communication  technologies  within  a  given 
enterprise and there are those who posit that this is in 
fact  the  primary  reason  for  the  organisational 
transformation  we  witness  today  (Schneckenberg, 
2009, Malone, 2004). What is important however, is 
that  this  organizational  transformation,  from  the 
pyramid to the pancake, has led to the introduction of 
decentralization  of  decision-making  in  modern 
business; (Schneckenberg, 2009). 
Lately,  the  trend  towards  lean  and  open  to 
innovation models of operation is increasing; Google 
allows their employees to spend a significant percent 
of  their  time  in  projects  they  initiate  and  conceive, 
whereas GitHub, the developers’ online community, 
has adopted the “open allocation” mode of operation. 
The  latter  is  the  model  of  operation  which  enables 
employees self-organize and deal with the problems 
they  think  as  important,  without  top  management 
guidelines or formal business structures at all. GitHub 
team  members,  inspired  by  a  common  vision  and 
maintaining an advanced level of communication and 
collaboration,  have  proved  that  this  decentralized 
approach is workable; it counts at least one effective 
application, as  GitHub ranks as a very popular  tool 
and repository for developers nowadays.  
In  the  following  paragraphs,  the  blockchain 
technology is defined and briefly explained, including 
insights to its main characteristics.
