[Applause]
or adults we are
Gorka Damania we work for time relax
which is a company and commissions by
and we met Foundation Florida
development and implementation of the
first they tell they open them for our
whole objectives of these session which
is that storm oh sure
Adrianna took and workshop arm and
understand look decent electrical
networks are what's their used white we
need them
it you know radon and why do you design
and as it is today and then how we met
excusing Reina we will show and how it
works in real life and you what we're
working we were moving human next and
what the future or a dozen women
tomorrow's so on the centralized or you
know you're the problem
22 is playing that anymore probably
every every single people here already
very little doubt about it okay it's
it's yes mom and em amassing
mean and it's not formal Isis and it's
not a problem that anyone has defined
its death marketing so what you're
talking about increasing terrible
problem here
that the fact that because the smart
contracts between deterministic we can
not very external API server to many
kind of planet whose non-deterministic
thing that communion the smart contracts
so we need to do some way to solve
resolving that kind of in the
determination of that arises from having
some computation being performed on
multiple amounts of a network or in all
the nodes in a network like is the case
or is my progress in etherium and at the
end of the day if we try to solve that
through centralized data it will
basically but having a contract have an
owner that can all ragged met on that
method that has multiplier so that only
owner can input data we are breaking
tampering censorship resistant which is
a the goal of using a smart contract in
with Ruby and in the purpose so the
question is how do you build
determination without centralization
that's that's a problem that we're that
we've been trying to solve so we came
with the concept of a decentralized
oracle Network where this centralized
means that basically it's 10% exists and
no one can decide with will watch which
will be the result of the contract
decentralization is just a way to arrive
to that madness with you know an Oracle
here means that there are some negative
laning
to the contracts and most importantly
an inter minor basically an entity that
express away the uncertainty that comes
from making an HTTP query where you can
have many many different terrorist
network errors
many different situations comparing
multiple api's for the Scimitar for the
same data how do you solve the fact that
they could be different and so on that's
that fail you have the Oracle and the
networking means that there's some full
of notes that are randomly selected for
making this work of aggregating and
delivering data into smartphones okay so
this centralized data networks should be
about speaking power so as meeting and
Trust in in a single know any particular
person so as to not have a point of
failure so when we thought that we
needed to find a way to have a DSL for
articles why why are programming
languages that exist today not enough or
something like a decent wise work so if
we want to build determinism I will
require explicitness so the code needs
to be really really clear about the
invention of the of the requests of the
big of the bigger requests we are
performing we don't want and any imbuing
but of course the human languages bit of
work we cannot use
two languages or saying I want to know
the price of these women were too busy
or I mean in my contract to know about
the temperature in second tomorrow and
so on and most programming languages are
also not suitable because they are to
reach in their comfort floor lowest
cultures so imagine for example solidity
it allows you to do looping and many
fancy stuff and that is not really
required for the purpose of simply
taking data from memory transforming in
its way at making aggregations million
so mister T is the visiting some
computations and then having it
delivered to your mother so we need
something that is we focus on
information aggregation something that
is between two things of more similarity
they are not the news for tonight so
when we started thinking of of this ESL
we realized that it needed to be
mastered so that is happening any
specific syntax it's not tied to any
syntax so that you don't need to learn a
new language that is that is simply like
a kind of grammar or defining data flows
and then you can have libraries in your
programming language that you like the
most JavaScript or whatever that you can
use the library support writing great on
the space so it's totally data oriented
it means that
at night and it's free so it's a
sequence of operators and operate on the
result of the previous one
and it needs to be really really focused
on what we are doing which is putting
information transfer minute I have it
deliver this is probably the most
important part which is that you mean to
make me analyst analyst I guess so that
we can predict the computing resources
that you will will be useless to us to
set some kind of price model it's
similar to to Casper something like that
and you also to detect any kind of wrong
incentives that we will see later
our security issues that will arise from
a month oran first so we introduced
written in the 2017 with an white paper
as a language that includes most of the
features then I just explained and radio
messaging for retrieval abbreviation and
the literary object notation so freedom
you can finger feel like something like
this that's it make something as I said
it is abstract so it doesn't it means
it's it doesn't have a literal
representation instead so a schema let's
say okay this is not any particular
language is it this is just representing
three operators so a script is a
pipeline of course here we're bringing
one of image line metal can be either
the initial panel of an operator
operator gold actually for an operator
followed by one or more arguments every
operator operates on the output of the
previous one and then that obvious
means that the final value for spring
will be the one of the last goal easy so
as a type system Reagan has its own type
system let's say that it's independent
from the one that you know for Janice
Priya normally need you for any other
languages it is scripted which means
that every time that you need to change
from one time to another and you need to
do it explicitly random so the types are
the obvious ones for value types of pool
and integral screening and there are
four complex types or structures that I
love for more fun system more functional
programming knowledge with it then
one next thing is that we can take raid
on the streets and serialized data using
the C board which is a standard for
encoding data structures in the Bible so
what we get some alignment we see here
that we can feed into you the resonating
which is an interpreter that is one item
that is at machine that simply takes a
humid data that we pray from name guys
for example and start interpreting the
speak and putting operators are applying
on triggers and then we will get the
final the final result basically here
this is business is just saying okay
whatever do you get from the MEI
parse in the station free time as a man
as a hash mark let's say you value store
and product get the value associated
with an EM field and then return that as
a boat so those are four calls and once
you
like this if you created like Jason and
this is the expo
so we're saying this is ivory really
come on a screen this one is for open
weather months actually so we have a
spring that says all of that you know
our situation
you need to I get and so on in 1325
which is really redundant then as as I
say we can we're not expecting you to
write bytecode or to do this kind of
structures because and this is not a
million at all what we do is rub that we
library so we have this witness request
library which is available on any n and
you can just you with at spring and then
start pushing operators into the strip
just like that with the same names let's
say are stationed at math at em spot and
this is actually metaprogramming so this
is the writing software that writes over
for you
this is an internally generated in this
week and the end when you you can add
one more like saying to Jason and you
get this structure for example or you do
to seaboard and you need Michael so then
we explain how these works in practice
[Music]
[Applause]
so basically we have for the faces we
start by just inserting the bike
actually well done with that what we
have selected to perform that task
because those notes in business there
may be selected randomly so that they
can correlate with each other and
creating graphics relations is very
vital functions so basically once the
subcommittee of the house is selected
their graduation transcripts that their
victory verses specifies the data under
physical specimens passionate acceptance
we met
in order to avoid failures provides from
American sniper so radio space there are
three different stages the first one is
the source this means that they relate
to the US because it's fun and they
could be many as you can see then when
we aggregate those data points into
singers at the point 5 negative space
similar to say like Moses which are run
by the witnessing notes themselves and
finally if we have moved a million homes
that we threw ourselves how do we get
this data
well the values which are actually from
my signals but I thought the candy house
backed up to - so further information
can be done by the request the creators
for example and Apollo is setting the
number of witnesses
and what we selected is that so and so
what they're gonna do each of them
they're gonna post resources as the
sources the aggregation script so that
those three points and integrated into
one single variable after that there is
no bigger thing to win them but I am
they don't do it the straightaway but
they just use the recommend removal
scheme press
the first commentary
[Music]
so it's so simple to understand like the
because it doesn't mean to know see the
fabulous Odyssey so once they
[Music]
okay so once a result is included with
me again the start from this was I think
they will take it and you will a poster
something original things the component
you mention is that with a population
and it is used by the nose here to
meditate transaction occurring with them
and showing improve it
[Music]
so yeah we start with basically the
weights a package with the string
antennas answer you can see how they can
parse it Hodgman
and then but notice that both of them
has a spoke in the end so basically that
means that both of them know how they
referenced in the invitation so then we
won't have a now and we have always
think
which will be you have as an example a
sample trip we will have to do a filter
using the division sound and then our
production in item have irrelevant then
the mean will be sent in but if we want
to fit around the earth like let's say
five for element and then the means we
change into more smoothly average to say
I almost want unit this is normally used
in order to as I said
so finally the tiny Street which is the
one where we reach consensus among those
are values that witnesses reported so
it's gonna it's gonna look very much
like the regression straight but this
time it's gonna be run by minor notes so
basically it takes a scheme to deal the
deck the data points that business is
provided from the aggregation strengths
and introduces proceed over the output
the game gets written two books and one
available this is this it's very similar
to the previous one but we have a more
harsh internal right so again we can see
how this future is important then nobody
will explain values notice how without
the filters interesting like a great
integrity
game in which money they know if they
haven't organized it will behave
naturally in order to prototype to
maximize the profit you will not I see
and also what we're doing is like most
other signal in this last stage they get
slashed why it is really important and
critical because they read intense
whisper to be tweeted I would provide
examples understand better in my team
way we have a gate operator it means we
have a simple an array of different with
this note and we are getting only the
first time but that's me it means like
an impact reporter and you will be some
kind of a witness no that will have more
power influence a result more if the
chord and a minor choose which one it s
the first he can then analyze how is the
filter gives it up so that means no mean
time scripts are coming so a similar
reduced average
in average customer again so you just
gotta learn to fine-tune them
[Music]
I actually
so basically this is this is using the
frontal box with a palette retractable
so that you can be out with the power
projects just a few seconds so you would
start just by doing you know from home
and walks with net upwards means I will
not do it right now because it takes a
minute or so and we're not that time so
basically this is our women request
which is now a small javascript file
where I imported the women because like
me okay one source for bitstamp another
pointless and then I got the applicator
with dolly and then I do everything
together
yeah like this human and request at
source but Saddam has started to test I
said never get arrested Natalia and then
I decide or am I want this they
requested me to be performed by four
different witnesses Frank McCourt
different nodes in the network last for
backup
that's expect better explaining a
documentation clustering then you can
set the peace for all the stages or
creating incentives for the minors
including those those transactions you
do box and you can send this case
in this case there's a zero within which
means that the Reapers can be
immediately perform enemy doesn't need
to be known in the future although for
many for many use cases it's much more
convenient to have it scheduled for the
future or we can delay a publication of
their request and yes zero and don't
send it from if you win it until until
we know it can be it can be so that's
that's in a request or or making that
word so we asked to return fire
[Music]
so when you when you do compile it all
this is actually just winning no this is
big in the name be compressed this is
just doing a note if compress the years
it's run in 2000 and when the javascript
is run is producing the rain okay
so when it creates the java screen and
turn that into engraven it's it's doing
some static analysis and it can tell
that the sources are even flows
fabricators given flow data is very
focused we can change and we can see
here what learns our type change so that
we make sure that we are doing things
right and that the final type will be
one thing that we can assume from from
from solidity so what what is d he's
taking a nap on firing in through in
into random byte code and putting that
inside our contracts older as these so
this is a Salinas contract that has the
random bytes inside so if we instantiate
these in our salinity with salinity
contracts we have the bytes and we can
send that into into the double bi to the
winner which interface for it to be
resolved by the winner so to use it
we simulate for example this is a very
very simple use case which is a prize
build using win that so what we need to
do is import in the day using women
library and saying contract recipe is
using women then that by emergence we
are getting a lot of methods that we can
use to control the vigorous lifecycle
sending requests having their their
souls rent and so on so here we are
instantiating their request we need to
embrace request body and then what we do
is send in the request like this we met
was request we pass the request and they
feel that you want to want to set for as
I we work for that rich notes to relay
the requests into into weather and then
when the result is ready which is
guarded by this modifier we can read the
result okay we read the result within a
structure focus open system algebraic
and the time allows your mother's
recipes will resemble that if we do is
okay we can know that we got an actual
result there was no failure or if
something failed because they gave me
ice pain or anything like that we can go
into a
all birthdays so much weaker from from
that situation I used to think of this
as an option for if I cannot resolve
this contract in a completely flat
trustless manner you see we met in an
automatic way with no latency at all I
can make this price in half and really
the agency that we work great if
something fails I can go into some
something like iron or something like
that
or recovering in that in that case
something that important that has human
intervention but I wouldn't be 99
percent of time running automatically
without human intervention because
that's a that's point so these in
addition to producing the contract that
contains device like these something
else which is what my phone which is
producing default constructor arguments
and migrations so it is detected that at
inside my project I have using women
contract so in created here in
migrations folder that you will be
familiar
a truffle to to migrations one is me
poor that imports all the women to keep
blessing and this will pass but it's
doing is detecting if we are on that
public into your network and then we are
in a public into your network will link
all the things related to this when its
reach interface and relay and so on and
if we ran a private network it will
deploy an instance of the WPI and
everything and they get that into your
your contracts and the most beautiful
part is that it brought also the day
migrations for my contract and inserted
the default arguments so it detects it
can read the signature of the
constructor of your contracts and put
the all values so that you you only need
to manually said anything that has not
that before party let's say but for
example it detected that the contract is
expecting the address of the wooden
bridge interface so it has the the
address right there it just okay what we
the women which interface that is like
right now and it's just some reference
implementation that we make that we
expect other developers to create other
implementations that may work in a
different way but there is an interface
with asunder
as long as you abide by the internal
interface internally I work differently
so the developers have the freedom to
use and other women women reaching the
faces that is not there the one provided
by by us so one man to life
I just moved here as in case work so on
the future frame one what the first the
first thing we think about is going be
honest in the best Expedia's basic Irina
Raiden spot used on precision payloads
coming from gift requests don't using
HTTP but we can think of other
initiators like taking data from IP is
scored by going and so on or even
reacting to weather events
so basically giving your contracts a
capability of sharing events thrown by
mother during contracts or if you
contract selecting contracts that
believe on another network which is
something quite interesting or events
are occurring authenticated experience
one other thing we're working on is
allowing some implicit conversions so
basically getting rid of the as map as a
whole thing and so on we can do that
because the operators are actually
defined as stream part station by SAS
map and so on so they are already
explicit of from which type to which
type so we can remove that because and
it becomes obvious at some point and
this this is one thing that we are also
quite excited about is done because of
house key forwards so super as I'm
looking for data structures
both both the body and how device relate
to each other so how what's they hurt
and because of that normally there's
some kind of expansion for example for
representing a 45x traditional here it's
using goodbyes 1845 so there's no
optimization here it's for a small
integer so small new takers only take
one bite because they are the bodies
below 25 or about - 25 impacting
automatically guesses knows that it's an
integer so we can turn this screen into
this other in which we are in basically
model 16 for all the operators and as we
know the change of the types we know
actually that five year actually means
45 one is 61 and so on and we can
leverage that the way that works and we
tend those operators from 2 bytes into a
single path and in this case the
reduction is around 30% because we have
literal span in the Suites where we have
very low amount of leaders and we are
just dealing with changing the shape of
the data and not using gets turn deep
like this and so on we can get after 50%
say which is a very important for alert
for long term
ability of men also you can feel that
with being a Frieden as something that
goes beyond witness beyond or networks
actually because on Ibiza at the end of
the day it's a versatile a sale for
performing data flows for the final data
flows and performing operations on the
way so it could be used not only for
women but for other particles or writing
scrappers for the indica from from
angular for making the next installment
of tools which are quite common in the
banking industry for example and so the
work we will be doing a brennan in the
medium term making a generalization and
detaching it from the cabinet from from
women so that we can have a higher-order
radon in which developers can define
their own stages in find their own
operators and so on and just leverage
let's say that the abstract syntax
behind in all the tooling that they can
transform that into may serve in their
various case so when will we be able to
use within frog into your main name
again
we are here we are almost there okay so
we need itself and has its own
blockchain you know it's like a nice
change to a few exciting by this email
we saw before with a rope relay and so
on so right now in a dissonant is
connected to two difference if you're in
this net screen to be inverting and it's
pretty too late we've they're all the
tooling is right there we are working
heavy on improvement illumination and so
on right now the visual information that
we need to type and you have really
comprehensive tutorial for creating the
correct speed that we that we saw before
and right now undergoing audits and we
are doing a lot of distress testing or
their for the following months we also
want to work on more bridges too because
technically them is done and some way
for cannot speak I mean that it's it's
bound to serve as many different my
contract platforms as possible and it's
expected to be launched on maintenance
for every next year so the price P is
pretty low level affinity for writing
things like define utilities that we can
create many funny things in in a really
easy way and in a decentralized way that
was not possible before
so or especially for tech con we try to
push the limits of what we have ran out
of all the tooling and what tween n is
right now and we came up in this small
that that guy
it's called impressive it's our rinkeby
Holly story complete in a few months we
can migrate time maintenance and
basically it's a potential market for
the point prices
[Music]
so you can try to predict each which
point we'll be performing best tomorrow
so you can see here all day all the
prediction volumes for each different
for each different comparing different
cryptocurrency right now is is waiting
in a surprise and here are your return
so we can I think I can double down on
Connie's so let's go with speed if you
see you point to send dick
so this is for tomorrow's markets so
they can predict what will happen
tomorrow
and that's when as tomorrow finishes I
can we throw my price and buy if I'm one
of the winners because your turn your
potential we pour for you for each
option and then for example we can see
here is the yesterday's market
predictions for yes that they are close
okay this work open yesterday but uses
the market work today
actually this is tracking what is
happening today
so tonight it will be closed and and
what will happen is that the contract
behind this will send the data request
with that women will attest what's the
actual result and consuming from three
different price api's and will aggregate
everything
push the result into the smart hunter
behind the tablet and it will allow the
ones that hold it for the most
performing and ripped off to take a
share of the other price okay so make
sure to check everything so that
government see how the markets all paths
which are the winners and hopefully get
some drinking it
game so the witness knows only you guys
right now behind this not okay actually
it's totally like an open for anyone
drama doesn't know reason very simple
I can follow one right now like longer
run it with that we met trust
[Music]
so this villainous on that note in there
[Music]
so many
let's verify the execution of the
telling on face yeah what what happens
is that as soon as you have the reveals
anyone everyone knows the Italians so
they come free communities the results
of Italian and n105 as the talents of
reasoning blocks what that means is that
other nodes reject blocks at the named
wrong time the research the motivation
that's that's no one there citing damn
the result is brought about you too for
example and that's very funny
so there the winded reach interface
actually verifies the transaction who SP
realization it verifies that the
transaction belongs to women and that
that has been accepted as they dumped by
the women Network as they tally for that
particular request so this is now
singing
you know right now look what happens to
the bees and like witness presentation
if you have your persistent or
intermittent error on my API like melmac
peso gets 500 the other three battle
response that's that's that's quite
important dirt in two different things
India campaign campaign out of the loop
and if it's true that I know want you to
take really prominent from that because
they are not guilty for that the witness
in notes so what happens is that the
slashing right now is on reputation so
there's actually some repetition system
behind these which simply as a score of
how often and how often every single
mode and most part of the majority let's
say how often they were not figured out
by tally function title is pits great
mental skills so it's important this
like to design the tallies very very
well so as not do that kind of stuff but
then it's true what some attacker who
come with some crazy request that varies
really really cheating angry eyes so as
to damage the system but actually the
way that the reputation system works
kind of prevents that because repetition
is pretty volatile and
change has really really fast and gives
you if you try to plan such a thing that
the point is that you cannot decide who
to punish actually because there because
the witnesses are randomly selected to
do so okay I will cause some notes to be
managed and some others to be rewarded
by I don't know who they are so this
what it's actually just accelerated in a
way that the system redistributes
presentation.we between main and not
because and at the end of the day their
reputation on task from emigrate which
means that just because you have
repetition you lose it
so basically in the case overtime if it
expires so you cannot have their
purification for forever and it's all
the changing hands so if you do that you
just jack you are just accelerate that
process so it's it's good for the system
I just hope you didn't on this time and
have it sitting in this table is this
something about if I read the white
papers that sounds pretty interesting
so I mean in those in these two years
it's 90 20% what we outlined in the
white paper we have pioneered
orientation site that is released it
down into the basically tending to
really understand what we're done here
so I think that will be quite quiet
because they the white paper is wet
expensive here cousin to publish
independent research but and technical
content on our video a lot and all over
a specific areas like repetitious and
many different parts so okay thanks for
coming
[Applause]
