next speaker who will talk about how
their knowledge and blockchains will
help help Humanity survive please
welcome Lisa a
[Music]
sword hello
everyone uh this is a lightning talk
meaning we don't really have any time
for jokes sorry for that we have to
start very being very serious from the
very begin beginning so the question I'm
going to talk about
today the problem is that we are very
small like as a blockchain industry I
mean on this picture you can see how the
rest of the world uh is trying to see
what is
blockchain if you want some more
specific numbers if we compare our
industry to other Tech verticals like
space Tech space Tech or biotech we are
something like like 10 to 40 times
smaller Frankly Speaking we are like a
small
dot but I think we need to be
large if we want to our industry to
prosper and take
a meaningful place in the
world and I think we need to learn from
mushrooms how to be
large what's it the difference between
blockchain and
mushrooms blockchain is a three mushroom
Network and mushrooms are a three
trillion mushroom
Network Three trillion mushroom network
is a really cool thing whenever someone
sees it they want to jump in because if
there are three trillion PE 3 trillion
mushrooms who joined it seems to to be
worth
it but three mushroom Network seems to
be a bit a doubtful activity so we need
to become
mushrooms that is to say it is on us the
blockchain industry to find use cases
where blockchain and ZK are a perfect
fit for huge world's
problem and furthermore it's on us to
communicate it to right people in right
Industries and in right countries around
the world because I can guarantee you
they will not figure it out on their own
first because they don't think about
blockchain then because they don't know
about Z
knowledge so today I'm going to just an
as an example give you three real world
use cases that are crucial for Humanity
survival and I'm going to use the
formula of ZK for refi computations and
blockchain for
coordination think for think for example
about the space think for example about
satellite coordination there are many
countries operating in the space and
many of them are not friends but still
they have to coordinate their activity
in the space how can China prove the US
that their satellite won't clash into
some us w space facility what they do
today they ask you promise yes I promise
but what if they use Ser knowledge
proofs for proof of fruit or proof of
hitting the specific coordinate instead
of just
promising but how should they coordinate
these tons of zero knowledge proofs by
hundreds of parties for thousands of
satellites 24 to7 without disclosing any
sensitive information they can use
privacy preserving programable
blockchain or think about
agriculture in many countries
agriculture is run by self-piloting
machines like computers with software
running on it if tractors cultivators
and bailers are out of operation for the
whole country its economy stops and the
country is in deep economic crisis how
can a small human Force thousands of
machines with different programs running
on top to report them what's on their
mind using Z knowledge proofs but what
about a network of thousands of machines
and thousands humans transmitting zero
knowledge proofs in arbitrary directions
24 to7 with privacy preserving
programmable blockchain I think about
nuclear missiles I know this is not the
favorite topic for most people but just
for 30 seconds if a country a has a
concern that a country B launched a
nuclear missile towards it his president
has several minutes less than five to
call their president and ask did you do
it but and if the president didn't
answer they must um launch their all
their missiles as a
prevention but can we prove that
something has not happened can one prove
that they have not launched the nuclear
missile or if they did can they prove
that this particular country is not a
destination I don't have 100% answer for
this one especially if we can prove that
something has not happened but I think
it might be doable and I think it's
worth thinking about
it so can zero knowledge help Humanity
survive yes
sure can blockchain help Humanity
survive
this is a bit trickier but yes but it
must be privacy preserving programmable
blockchain no privacy no blockchain
adoption that's simple that's it thank
you uh thank you uh for interesting talk
um I also strong believer that
blockchains and their Pro knowledge will
help Humanity to reorganize in the
future and thank you again so if we have
any questions we have some
time uh okay uh then let's uh try to uh
kind of uh stay together because the
next sliding talk will be started in 2
minutes thank you
may I answer the fourth one yeah if you
want yeah about proving to the partner
that someone is not cheating um if you
are a
computer I think and she is a computer I
think it is very
easy um if one of you is not a
computer it is tricky because when it
comes to uh bridging data from the
physical world uh into the digital world
from my perspective this is this is very
complex still very tricky thing and it
wasn't uh resolved so far there was um a
paper in 2013 um written by some
Princeton Princeton guys about like
utilizing zero knowledge proofs for
monitoring the state of nuclear
facility um and they assume that there
is some nice solution to um like an a
nice solution for a Oracle from physical
world to the digital world but up to now
there there is no such solution as far
as I know and uh that's why all the
cases I described they are digitally and
Native from the very beginning so
something exists like a piece of code
from the very beginning like
self-piloting machine or like satellite
