BAJJI, VERSION 2019.6.11 2
C. Why it is happening?
Why such contradiction is happening? Although we can
contact easier and get information a lots, we feel it is still
very difficult to tell a person/content we get to know is
trustworthy or not based on much information we have. It
is simply because all are free and unlimited. Registration
accounts on SNS is free. Posting text, image, or even videos
is free. Click like, share posts, retweet are all free. Also, it is
unlimited. You can click like 1,000 times or more a day. Both
getting followers and follows are unlimited. For example, if
someone has more than 100,000 followers, we do not know
whether he/she has really 100,000 funs or not. Out of 100,000
followers, he/she may have only 1,000 funs and rest of it might
be anti-followers. It often happens. No one knows for a fact.
For most of consumers, we think NES (Nintendo Entertain-
ment System, Family computer) released in 1984 was the first
computer. It became very popular worldwide rapidly. Super
NES, Play Station (SONY) were released in 1990 and 1994,
respectively. At that time, issues of software developments
was limit of memory. ROM (Read only Memory) was very
expensive. For example, the first RPG, Dragon Quest, released
in 1986 was provided by only 64KB. It was amazingly just
64KB. If you take a photo on iPhone, one shot is larger
than that. In 1995, we all recognize internet revolution by
Windows95 and Yahoo!. So did we. Before those launches,
most of us did not understand how to use Internet. In 1997,
Google appeared. We had gotten a wing to fly Internet. But
it was not easy. The only way to get connection with Internet
was dial up. Its connection speed was only 28.8Kbps.
Although internet is new generation of technology, all were
inconvenient. The first broadband called ADLS (Asymmetric
Digital Subscriber Line) was introduced by Yahoo! Japan, a
group of SoftBank in 2001. They provided ADSL modem by
free to consumer. Internet connection speed became fast to
2MB to 4MB. We may say that it was the first freemium
economy on Internet. Simultaneously, CPU performance was
improved for example, from 150MHz of Pentium in 1996 to
1.3GHz of Celeron in 2002. Gradually, we are able to do
various things on Internet.
In 2004, Facebook was released. No like button at the
beginning absolutely. No function of posts, share, nor message.
All users can do is only post one photo and input their occu-
pation for example name, birthday, grades only. Facebook has
released free function one by one in line with the development
of Internet. In 2006, the word of Web2.0 was paid attention
to. Its keyword was free. As of 2019, most of people think it
is normal. It is surprising that posting text, photo, or video on
social network services are free. If you post a single video,
you would consume 10MB. Its size is similar with the size
of 100 games on NES. Business model of Web2.0 players
is advertisement model. First of all they need to gather users,
views, and impressions. That is why they provide their services
by free to get impressions more. In addition, they had to
provide functions that users can not help but use. The first
one was like button released in 2010 on Facebook. Since they
need impressions more, users can click it unlimitedly.
Most of all functions are free and unlimited. Is it good
features of Web2.0 services. However, it is also harmful
function ironically. It lead rapid expansion and social changes.
Arab spring in 2010 was said to be brought by SNS. It also
caused large amount of fake contents and excessive criticism.
Web2.0 model is approaching a corner. We believe that it is
time to re-build the current social web. We have an idea to
solve these issues. It is bajji.
II. SERVICE CONCEPT OF BAJJI
A. Visualization of trust
BAJJI is a new generation of SNS using blockchain
technology. What we are trying to do is visualize trust
between people.
For the last five years, variety of C2C services like Uber,
Airbnb and Mercari have been appeared. We become to be able
to select someone we do not know on those platform. Why
we could choose someone? On Uber, it sounds dangerous you
can take a ride on a car which driver you do not know. You
can stay somewhere even though you do not meet with its
host. Why we could select unknown person? It is because we
see rating. You just check its rating. On such apps, rating of
drivers, hosts, or providers are disclosed. When you take a
cab on Uber, you do not see drivers basically. What you see
is only rating. It is just number. Once you get off the car, you
can not tell name of the driver any more.
Rating is a kind of credit. Credit is built by past perfor-
mance. Most of all C2C services rely on rating. One says that
we entered big data era. However, no data regarding to trust
is stored yet. Trust is built by reputation or expectation gained
from family, friends, or colleagues. It is also established by
honest behavior. Once such trust data of each person is stacked
one by one on SNS, we never see fake news nor excessive
criticism. Visualization of trust will lead to solve big issues
on the current social web. Since one’s trust is built by others,
visualization of trust would be deterrent to go wrong.
bajji is named after a badge which is symbol of trust. A
badge is used for lawyer, police, and member of parliament
etc. Our service concept is giving bajji as symbol of your trust
to someone you would like to convey your mind or sympathy.
Its transaction is recorded on blockchain which will be never
tampered. Important thing is that bajji is limited. It is not free
nor unlimited. New users on bajji will receive 30 (to be fixed)
bajji only first. Since it is limited, users have to consider to
use it. As a result, the number of bajji you received will stand
for your trust from others.
B. Backgrounds of designing bajji services
Our vision for bajji is building trust-based world through
blockchain technology and providing innovative services to
