hi everyone I welcome to Japan are you
enjoying Osaka
oh yeah sounds great
today I'm gonna talk about new voting
systems and I just want to tell one one
just one simple key message today which
is read trade our voting system for beta
one such as majority judgment and
quality voting also changes world to a
better one and before I give my
presentation let me introduce myself
quickly
my name is Masahiro yes please call me
masa and I found it Alice in 2017 which
is a social media using ether and
blockchain and I'm also in charge of the
radical exchange Japan chapter which is
created by Glenn wave the famous books
author radical markets I think most of
you know about erotica markets and our
company is also researching mechanism
design with famous economist otakus a
guy from keio university which is one of
the most famous private university in
japan to create Alice as decentralized
as possible so that's why I'm looking
into the new voting ways to to create
our service more decentralized one so
today before I introduce my new voting
ways I want to ask some questions to you
why did brings it happen also why was
George W Bush elected as a US president
in 2000 us pray
yes president election although our goal
was recognized as the best candidate
I think there are many reasons for that
but it was due to the current voting
system majority rule having huge defects
for example people can't reflect the
strengths of their preference also
easily result in a spoiler effect I will
explain what spoiler effect later and
it's relatively easy to manipulate as
well so I want to introduce two weather
alternatives to the majority rule first
one is majority judgment and second one
needs quadratic voting
so what's multi judgement it's this is
the image of majority judgments so it's
like this instead of choosing one option
voters give a skull to every available
option on x-axis you can see the options
and on y-axis you can choose how much
you like each option and after voting
you can calculate the medium of all
options and the option with the highest
median winterbolt a majority judgment
guarantees the contentment of the
majority of all voters and it also
prevents the spoiler effect which is one
spoiler candidate in an election draws
the draws boats from a major candidate
with similar politics in case of 2000 US
president election do you not remember
Ralph Nader his sudden came up and he
ate the bolts of Al Gore so as a result
accidentally George W Bush won so you
can prevent this spoiler effect by using
majority judgment and the second
important way is quadratic voting both
robot with credit so if you want to
by one boats then you have to consume
one credit and that the costs of the
price of votes increases quadratic
quadratic re for each boat so if you
want to put two then you have to consume
for credit and three four nine credit
and the option with the most amount of
votes wins
so cuban voters are able to express how
strong they feel about a certain option
and i i've read many documentation about
credit reporting over magic judgment but
there are very few use cases so we
actually try to use them on our service
so we use majority judgment on a lease
for choosing a new category alice is a
social media soul which has which has a
category on top page so we use multi
judgment with choosing a new category
and also we use quadratic voting for
choosing main strategy of alice in 2020
I don't tell the the detail outcome here
because it takes a lot of time but I'll
share the summary paper which is created
by totaku Sakai the The Economist I
introduced to you so just I share the
good points of those voting weights
first about a module judgment which is
quite simple so you don't have to
explain what is majority judgment to
voters also it has high resistant to
manipulation and it also sketches a
picture of users overall preference as
by product and the last point is very
huge marriage for me which is result is
compatible to border rules which is also
a famous boating way or majority rule so
you can compare the outcomes and decide
on one with more confidence I think this
is a few huge mate and also the good
points of coded voting is it's all so
simple but you need to explain a little
for voters because there are no way to
consume your credit point to vote now so
but it's really simple as well and it
can reflect the preference of a minority
that has the largest interest in the
particular poll
glenda the also of radical markets also
emphasizes him in his work and it makes
voters think more because it has kind of
gaming factor so resulting in people
taking the boat more serious so in
conclusion majority judgment functions
much better than other voting rules such
as majority rules so implementing is
relatively easy and as the purpose of a
platform the excel in for the result
gives is also a nice purse plus and it's
one of the greatest voting systems not
only practically but say logically
according to Professor guy and Craddock
voting provided an interesting outcome
more difficult to implement compared to
module judgment but worth trying
depending on the poll subject and
especially beneficial if you want to
give a power to minority so from this
product our city of soda will talk about
the length of the presentation
konnichiwa uh hi I'm sorta ishi CTO of
the artists and today I intended to talk
about some technical topics however it's
not so difficult for experienced
engineers the weird boat in contract
actually there's not nothing to say just
period that's all so today I'll talk
about the following show three obvious
said majority is not either boating
system however there's no silver bullet
in other words there is no airtight
alternative is the hawa I wanted to
argue that we engineered children social
choice theory including voting systems
there are a lot of voting systems and
each has its own strengths and
weaknesses majority majority judgment
and cold quoting are just one of many
options it's accept their own proper
purpose for charge fortunately just a
huge amount of brilliant knowledge in
this area I just started to learn about
this field this year but I believe the
doing so can help engineers like us
after reading an e-book change a balance
to achieve good system you have to
understand what what we are building
anyway it is interesting to note that
there is a conference in this area
called the NSF CEM decentralization
conference which has been around since
1970
I'm sure imply
implication of this centralization have
a chance since then however it seems
like in the latest conference they have
also been discussing rock chain but I am
trying to say is there is a lot of
information out there to be studied so
to our engineers in this region do
consider leading up on the some social
choice theory and let let's go over to
build our structured government system
our vision to empower the individual the
user thank you
to tick before we finish our
presentation attracting to reduce the
paper as I mentioned and this is a
summary paper on multi judgment so you
can learn many things about the magic
judgments a good point and also a bad
point so please take a look at it and I
want to say a special thanks to
Professor other Sakai so to conclude our
session my presentation I'd like to
share one story relevant to Japan about
what happens when you use majority rule
have you heard about our Minister of the
cybersecurity anyone know he's 69 years
old and with the best security policy
why best because he doesn't use a
computer also he said he has not ever
used computer before and he also said he
doesn't know what a USB is again he is
our Minister of cybersecurity so this
may happens in under current voting
system I think this is fine
and ironically the next next speaker is
the IT Minister of Taiwan and also known
as a genius programmer so I think see
gonna talk about more detail about
coders exporting and I really refer to
it so please give her a warm welcome
thank you
you
