you
Thanks all right ah oh I still have one
more minute bonus that's that's awesome
ah what's gone all right so thanks so
much for having me I'm really super
excited to be here thanks a lot for Ming
and George and Laura and Hudson and all
the other helpers please give them a
hand because I think this is a very
unique occasion here and you're making
it possible thank you so much so I'm
talking about smart contracts as
perimeter ization and I realized when I
was running the presentation by
Christian ip's know that he wasn't
really sure what it means yes he's not
the only one but I am going to try my
best to explain exactly that so i'm
heading dt i'm working at IBM i'm
working in the project blue horizon and
we are i'm very proud that we're
actually really having a product there
that is using the blockchain it's not
just a project it's something that is
actually ready for production so and i'm
also writing a book about a serial it's
having a subtitle a serum for
non-technical people and one of the
things that i'm taking aim is that the
distributed ledger talk is something
that is very confusing and that is
giving people the wrong idea what to
look at when they're looking for ideas
for block chain so people like this used
to be the ledger thing because the
letter is something that's around for a
long time and the block chain obviously
has a lot of very good features that
make it very good just repeat a letter
however that's completely the wrong
track and where you actually should
looking on is the guarantee of execution
because that's the reason why for
example bitcoin is where something it's
not just because it couldn't be
duplicated in the past or you can
duplicate it now it's because nobody
will be able to duplicate them going
into the future that's why they have a
value and if we look at the theorem as
the world computer it's also something
where you think of moving cogs right i
means if you you put something into
a transaction and it's going to eight
thousand computers and is changing bits
and bytes there so it's not a world
ledger that we're talking about although
on the other hand that's the URL for my
book if you try to really get your head
around it you look at stuff from
different angles and that's also what
I'm trying to do in my book is I'm
explaining where you could actually have
by taking a different view have a
different inside and this is something
in games development there is that book
so to say about how you design games is
called book of lenses so I'm not
inventing this and of course if you look
at Bitcoin in the end what you want to
know is what's the balance of my account
of my Bitcoin account but where are the
smart contracts there so there's the
question of course our smart contracts
really something that you can do with
Bitcoin and we're on a serum conference
here so I can be critical and what you
can do is multi stick with Bitcoin right
and then everything that goes beyond
that you can put a hash in the
blockchain and Bitcoin and then you can
say okay but I have clients that all
agree that a certain hash is going to
mean a certain code and how they get
that code doesn't matter and then they
gonna execute it and that's as good as
having the code on chain however and I I
oh that to Jolla Tony one researcher
like the earliest researcher IBM that
was looking into Bitcoin and blockchain
there is an analogy here that could be
made between FTP and HTTP so there's a
story that at IBM when somebody came up
with yeah we should be looking at a PP
HTTP they were making an experiment
because technically some people said
well HTTP is semantically nothing
different there's nothing different than
ft what ftp does and the end you get a
file right that's that's it and so they
gave them the task who write a web
server one guy was writing at an ftp one
was writing in at HTTP and after a day
that guy with four HTTP was done and the
guy with ftp was after week he was still
not done so they canceled the experiment
it had a clear result and IBM started to
look at HTTP and this could be taken to
the difference of having the stuff off
chain or having
unchain because of various attack
vectors that we've been speaking about
this week these days so blue horizon is
something that informs very much how I
look at the blockchain at the moment
because it's something we've been
working on very hard and we've also
sometimes run into insights that maybe
we hadn't hoped to find what's blue
horizon Blue Horizon is doing analysis
at the edge that means that we are
basically making possible to have the
analysis code running as close to the
sensors and the edge as possible as
opposed to having it in the cloud so a
very common situation is something like
this you have a lot of sensors those are
the bubbles at the top and then those
sensors they could be antennas for a
software-defined radio or a temperature
or smoke detectors they sending a lot of
data to the cloud and that is very high
volume data with a very low individual
value that is then analyzed in the cloud
to make high value out of it so what we
are striving to do is to reverse that
and have in the end high value and low
volume so we're sending out the analysis
code into in dhaka containers to the
edge and at the edges deployed its
unpacked and then runs and the edge and
what it sends back is only the high
value low volume data that's in a
nutshell what we're doing and you could
be looking up much more explanation and
you can even write your own applications
on top of this platform and this is the
URL when you can go to and check out
what blue horizon can do for you we will
we are in the process of open sourcing
it we are going to have a very have a
new website to where we're going to
explain how exactly how you write your
platform if you have a Raspberry Pi you
can immediately take part in the use
cases that we're offering their we're
doing something emulating flightaware
where you can have your own weather
station plugged into our network and
what we have now is a map where you can
see little raspberry PI's running all
over the globe and picking up flight
path this and doing networks be tests
and you can immediately plug your
Raspberry Pi in there and then take part
in this and we're happy about everybody
and going to support you personally to
come and take part so part of the whole
system that we have there is that we
have a sequence that is going through
registration of Raspberry Pi and the
network then it makes an offer offering
its data somebody else who's playing the
entrepreneur or the use case is making a
bid to have a subscription to this data
stream to create a new business model
format or make a new offer then that bid
is accepted the functionality is
deployed the analyzation starts and then
in the end there's payment so out of
these things the deployment and then
allah is analyzing is something that we
do completely peer-to-peer we don't need
the blockchain for that and the reality
is that even now we're even taking the
blockchain out of the equation for the
offer and the bid and creating the
centralized because it's just not
scaling it's just not fast enough at
this point and because we want to have a
product that people can use we're
backtracking at that point if we're
looking at smart contracts ideally to
have smart contracts full circle you
want to have something that goes like
this you have an offer it is being it's
agreed to then at some point you deliver
the data thank you for low light show
then you then at some point you confirm
and then the payment comes and what you
really want to have to have a real smart
contract is that the confirmation comes
from a third-party trusted Oracle or
ideally even you can have in solidity
code that verifies whether the data that
has been delivered is really worth
something and then does the payment or
refund this could be thinkable if you
have weather data you could verify
whether it's an total outlier compared
to its neighbors then it's probably
noise and then you don't pay but the
reality of it is as it is right now
we're cutting this out and what we're
really using of smart contracts is only
this they offer agreement and then in
the NDP and again we have this gap there
so in a sad way you could say that also
at Blue Horizon we're just using the
blockchain very much as a distributor
letter and we are
using it certainly for payment than in
the end but this is also because the
reality of our project was that we have
technology in search of a project and
not the other way around and we were
basically given a lot a lot of stuff
that was supposed to be in that project
and this way it was initially called MTN
or multiplying things needlessly I want
to share very quickly some problems that
we found with the theorem and some of it
is not so surprising speed is really
standing out in a way that can be
pinpointed to it's the right how slow it
is to write as this very is exactly what
making the problem scalability I don't
have to explain that but of course we
ran into this somewhat unexpected we
really have huge bandwidth problems but
event that I healed more or less by the
light client and then of course yeah
scale I said that before so and it's
also a little bit to doge I won't get
into into that but sometimes there are
inducing crises that are fun for the
guys who make it but to use it it's not
sometimes not helpful then we sometimes
run into bugs to that we felt like if
somebody was really using athyrium how
can possibly be this box still in there
the strength availability that we have a
contract language that you can actually
use and to write complex and resilience
you can knock out all the nodes with one
load survives is still going to survive
but still coming back to the DLT on
smart contract that permit realization
if you have functional programming then
you have first-class citizen functions
and if you have a function you just
don't Merson you don't just throw static
parameters in there you want to have
functions going in there if this is a
function and you have static parameters
you can define a car but if you can
throw other functions in there you can
have a whole new universe of stuff
happening just from one starting point
and so what you can do now is if you
have an init function of our platform
you can give it a static parameter and
that's the prize in this case this could
look like this but if you have a little
bit more then you can have an
acknowledgement function that is then
called in the last
line are down there and it's giving back
as status to the app developer who is
using our platform now you can even go
faster and can have the whole my init
function as part of the app instead of
the platform so the whole platform is
calling back into the app and now it
gets interesting because you can also
have caused get beyond the convention of
having an init function you could do it
like this or and the future you could
also hope that you would at some point
have the possibility to have this which
is exactly what Krishnan said today when
solidity comes to the point that it
actually allows you to have first-class
citizen functions this syntax does not
exist yet but this would allow you to
set the price immediately by a callback
that would say check out what the price
of the dollar is at a certain day to set
a price that is not a static number but
that is looked up in that moment so yeah
this is yourself the distributed letter
I really hate it but maybe there's more
to it than I used to think and this is
just the current thoughts I had on it
this is my twitter handle i'll post the
links there thank you very much
