I'm here to judge us in Germany in three
quarters listen I'm once up and now
working for nuns I mean to say is in
Krypton community in Seoul there are 70
people all living and working together
so and recently I like the polyster and
recently I organized a local communities
Developer Conference which name is so
first 70 people in nuns are all the
crypto related people but including me
we did not use venomous anti to split
the peel after we have dinner together
it's because it is really hard to find
my friend using animal skin hi so
actually we use in actually in Korea we
use compain which is equivalent to venmo
to split the bill because those services
are providing the features to find my
friend using the messenger feature so
however as the ux t acquaintances is to
coming to institutes and mike refer to
my friend using darkness so how many are
using unison there are so many people
are using illness then how many has
states to use in
how many has disease PMS is um yeah not
many but people who use ENS frequently
definitely feel that it is really high
release so if I know your illness then I
can very easily know how much if you
have and how much die you have learned
from me right now or even how much you
got liquidated from the main renowned
biases type in your ears into the
industry so so if they're 9 3 4 s comes
up as a lightweight pirate renters of
solution so which place figure out this
is either penetrate course knees
it's a kind of Harry Potter stuff he
said get to into the medical work where
we can use them people in Moscow so
let's see how it practiced the users can
can change into the masker world by
depositing your stranded tapas and then
they go into the medical world and using
the mobile in football they can make
some confidential tradition each other
and the relator can create the mobile
transactions and submit that rejection
to the interview using secure mobile app
and the important thing is that the
relay also aggregates the fees so okay
this is just and by the way the users
can we throw their money back to the
mobile world submitting a valid proof
this is just a brief explanation about
how it breaks and now we are going to
talk about the deep technical details
about people either in three quarters so
the first priority of the design was how
much dick is nurse friendly and the
second one was how much business
friendliness and the third one was mr.
friendly is so I'd like to employ I
started to use the me more on first
because removing one is the one of the
lightest part of building comprehensive
transition so it's transaction of
consists of a randomness and a value and
it expresses the TSO as a point on deal
on the other two card using a pistol
movement so it can hide those secrets
while it allows the homework
culturally Asian so this is hidden like
the same IDenticard I added to point of
the curve therefore using so imperfect
hiding features we can verify that the
sum of the input values and the sum of
the outfit is equals so you can see that
the coefficient of the base point on H
equals 0 becomes zero cost only so we
can also consider a prediction using
this equation but it's not enough to
make a robust condition therefore first
because the zero sum replication works
on a cyclic group to prevent the off
wall and the underflow inside the home
were free consulation
we need to restrict the range of the
values inside the check piezo and
secondly we also add some metadata in a
marquis we can't we concatenate the es
to any address of the topic we
understand and expiration time so the
expiration time means that the
contractor contract will not accept if
the block number exists expiration
hunter and finally to make sure this
transaction is confirmed by the pool
party we as a snore signature by the
sender and the recipient but the problem
is that actually is not preventing the
tracking of the transition flow so
actually green which is the most popular
importantly implementation see crystal
privacy by having no account and
contouring
in on interview we can not prevent the
track of the change in RAM so therefore
ninety three quarters uses C caches
commitment only para scheme to hide the
input input CSS so with the treatment
only price in suggest nurse allow us to
generate a an inclusive proof without
redoing the commitment and also prevent
the double also prevent the double
spending by using the knowledge wire
which is deterministically derived from
the commitment finally so we append two
more CK start with the first one is
impressive proofs of the span test with
the samples of the no defiers and the
second is that the middle and bottom
because it is because we hide the
impacts of area so if not isn't not
anymore able to verify the removable
using the homomorphic calculation so we
need to make them city stars proof that
just guarantees that all the hidden
values are following the removal Ponte
Preta me the next part so as far as C
cable la friendly data structure I'm
pure top purpose virtual mountain range
for an efficient a pen on mean vertical
tree data structure and green is now
using that in interview 9 3/4 it uses a
slightly tweaked version of a
recommendation range that uses elliptic
curve
- repeat - but to compute the whole
notes so most of all in Pearson
replicants arranged every knows our
every note is the point on the baby -
current so we calculate the lead note by
the scholar multiplication of the lip
position and the live item and we
calculate the French note the principal
value becomes the left node Y value and
right now the molecule is multiplication
of the left node Y value and the right
right
finally the root value because the
stolen multiplication of the week of the
merkel mountain range and the product of
all Peaks we call this big bang in
merkel mountain range
so with this construction a 16-bit penis
Merkle tree which has 65,000 least
achieved 10 million constraints for
rolling up 64 items at once
it is generally because a firm Istanbul
the cusp guests cause poor circulation
reduces sloth so it will be able to
verify around 256 rolling up 256 items
at once so finally we can jump up to the
Torah performance of the roller with the
Optimus igual just like plasma we can
use a challenge system to skip the CPS
knife computation so therefore we can
read this aloud as opposed to verify the
sickest interpretation is that
unchanging vision
therefore in Petersburg in Paris
perversion rolling up kisara 3 million
and spurt injection but Optimus tabula
on Nico's on about 147,000 Kasper
transition and in Istanbul it only
concern around about 50,000 yes per
generation we need to actually is much
expensive than our general Lola it is
because it contains alarm which is nurse
proof to make the transaction as a some
comparator transaction but it is still
very reasonable because the original the
Bayer years training total transaction
cost around 50,000 to 100,000 cast
so as a result of return is passed
through inter magnet drinkers or is a
towel and some deep-lying for not using
them so first anyone can be a real laner
and we can decide their own transaction
fee policy but to submit the optimist
you want the relationship to pass some
states to secure the product to you just
thanks for the challenge system since
beings are therefore being a real layer
can be considered as a kind of a
financial part which gives some revenue
for the transition aggregated transition
be against regarding to the closet space
therefore we can also make a kind of a
towel system like delegating some states
to receive some dividends of the
transaction fee revenue
so the future word is first one is
optimization and the second is related
plan and mobile client and because if we
also get some instant finality if we Ola
without the optimum I mean it means that
if we compute all the sickest our
computation then we can get that is the
finality but if we use up to mr. Bhalla
we need to give some challenge period so
we we lose the instant by on limit
therefore if we change some construct a
network of the real layers then we can
not is not exactly an instant finality
but we can offer you to provide some
security of instant finally with the
states of the relators network and what
we have to do is gently just destroying
the hypothesis yeah strike that
pasty-faced so here's the summary the
remaining three choruses removing the
protocol and coming month Allah Christ
came together and he uses Peter Suber
the mountain range for an efficient
secure all there for each chain is able
to pan up to 256 items at once and the
optimal provides deterministic front
proof without any t88 problem and also
it reduces the cost down to 15,000 yes
per transaction so this is the
implementation so if you like that
please give me
some top stars or yes or if you like
that I'm looking for teammates or teams
you can support this project so if
you're interested in this project please
let me know so thank you owe me some
pressure if you want yeah we have four
minutes so you can go up there is a
stable internet Reza yeah um the devil
yeah but on the Internet
[Music]
I already prepared as an Iranian and
proves generic growth and some samples
and extras
[Music]
but it's amusing
so the first song is war 2 memorial
transaction which spend one point mixing
so we can make some appointments by
depositing to BSU Chinese and the second
round is spending to see the new
traditionalist which is right throughout
by the personnel
so it means we used continues to include
CSS and for once and make one change so
if you have some removable trench blog
post and you can aggregate them to use
or a one so as I know many some part of
all uses two inputs and two of us so
there was the only 64 at once so this is
the wizard will be rolled
wallops 32-bit border connection service
in perspiration
how long did it take to build a parrot
how long did it take you to build it I
started to design from from the tree and
finished specification Iran from July
and started to build from honest
full-time
