[Applause]
just
a little bit of ourselves so we are from
Table seven states and quite simply
asking about a plan or customized
prospect we have a mistake might come to
us after that and so we are jumping in
at least try to stay above the
consistency where our expertise come in
part from a nowhere and unabated work
body lower focus has been developer
tools to have original diversity
[Music]
ministers including a certain spot
context certainly an explorer and the
models be combined into a single
web-based product
we love this project
[Music]
okay
[Music]
that means difficult what - photoresist
applications we come on enterprise world
you know that DSL has always been one of
the you know you look at that for
maturity
SPS not domain-specific language is very
important for for real word and
minimizing states and today in salinity
is very generic everything has to be
brewing companies so there's no specific
optimization solutions and the second is
the design of solidity and other vendors
they must assess SS and SS so you know
gas ourselves why so difficult
discrimination of scenario why is it no
random number is why is that no checks
on supporting today it's because the
cylindrical has to be able to criticize
actions on the project if any of those
cause in their place under deterministic
behavior or gas fire you do need those
features Tammy put those features in
view functions of European countries and
and so that's a great out there most of
the vendors today so that's where you
know we both have already no reason to
be able to try to create various vessels
to province because if you don't have
consensus
cameras or any conferences that's not
something we say okay so how who shared
over my time and talk about how do we
address the first challenge the first is
solidity is Tory complete and its
general
there's no domain system seniors in that
language oh I'm sorry
Ezra so I was some of the
go ahead so first of all why do we need
a ruler is 111/2 I ask this question
nobody's not contracted automated stress
on a triggered by end results in their
eyes their very definition it's a
perfect match you know my disciples must
be transparent regions and the musical
blockchain is perfect for Pat Wall
Street fescue rules today and rice go
sizes and rules engine is essentially a
decision trees in rules will be living
in a decision tree using a large driver
impacts it relates financially absolute
increase you know so if you have
multiple interacting rules in trees that
every single change on this side
[Music]
how we do our ascension into the side 13
a sake as we know if we want to add a
puppy they must be some new clothes or
some new instruction but you know whose
engine we don't do that because we know
a half of half of Harvard has too many
Howard we don't want to do that so we
just separate that we had a numerical
rule and we just build a new pasture for
years and neupogen also e is compatible
with the original if you want so you
should go to our country you can buy
with the final summer clothes and she
has V and when the passer going inspired
oh that's the whole walk when my summer
when somebody is 12 and a naked Testim
case a mommy
and so when when somebody is cute the
contrary I will find all the rules and
you must resist something our company I
want to modify because there are lots of
horrible not everywhere I will need to
be modified so he was not address that
and or handle were together and just
feel out of something like and so we
just go to our demo and this is our
website you can go there and get more
example
yeah oh so
our looks
they were resetting it and our first
instant okay Alpha Centauri is attention
that's we define a person who has a
number of edge and locate which means he
attended a school for a while and
packets for his money and this is we
define a structure to share some money
to those person and we have to we have
one is called awesomest which will store
all the person and total back in here
and we add a new numeric encode effect
in certain Factory in series just like
notify our pendulum which were about
shooting money in this example dance of
the package will be alloyed per hour and
all and we just say in 2000 and we go
through a little car first
II just you just write a rule like a
world woman he can be a stream more each
of the men and the window will will
contain several conditions as you can
see you can say oh I want to feel to
that last person who's and is greater or
equal than 65 and water is fertile and
equal 5 and also our package must must
have come greater than 10 yeah and if
you find if our intro final edge and me
any modifier objects is
is in these conditions then he will
check out this inspections like we will
add the person and depend on us and just
- our photo packets in darkness
yeah and another one is how can we add a
new person - here we can see we have a
list here and we create lots of person
of judgment and then that's insert to
tell our Endora to modify a piece this
object and the last action is we well
called punching or the final rules it
will just delete all of the rules and
and just just do these actions so let me
compare yet
first of all we had a person like the
first one okay we can just check was
once they happen and we at the spawn is
this is five and twenty and to
Sara because these villages large or or
equal to five so we want to adhere to
just be wrong okay now we have three
person and certified classes now we
image the pay machine and just check all
of the person liked on the Negro but he
didn't get any money because this is
only system for years second one jacket
$10 and sir one known angle and dollars
yeah and as though we can just check the
baggage if he just he just spend $10
okay
that's our our table full of loss engine
if we right scan you can find more
examples on our website
research coming off to say that's the
verdict you retired the laundry to them
retire like 15 leading to the minutes if
you retire at 65 67 so it's really
important that's the top and have all
this cool you know who gets love to
retirement age so I'd actually show up
[Music]
so the next one I want to talk about how
we saw the second review before the
first Apollo is noting specific stages
for the language the second problem is
no separation between suspect
any final winners we see you be my kids
1.1 X separated so basically we could
call this an auxilary application and
what we mean by
auxilary application is an application
that is really assisting the end-user of
a blockchain
application and essentially transforming
full node data to make it available to
the end user in a useful way
so this is not a second layer solution
and does not play a role in and network
consensus at all and it doesn't play a
role in updating the blockchain state c0
read only one axillary application
example would be like a Bitcoin core
wallet so as we know we have episodes
and the system the Bitcoin states
represented by its global collection of
unspent transaction out please but the
Bitcoin blockchain doesn't actually hold
the account balances so it uses account
balance in Bitcoin axillary application
i.e the long so there's a purpose for
ancillary applications they are safe
because they're really just a helper
right so it's important
application can't really make the
blockchain do anything in college so in
example is yeah Alice here she's got to
the point if she thinks that she's got
three for some reason that she tries to
execute a transaction that might
actually succeed so they can't make
blockchain do anything that song so the
smart contract search engine falls into
this category of what non-consensus code
and the search engine that allows pure
view infractions to be executed off
chain with arbitrary programming
languages and rules and example this
will show you minute is it's reading the
public data that exists so for example
if there's a public variable the
compiled traffic to the Guinness and
service automatically you can go in and
grab that information automatically so
it's a bit of an overview of the smart
contractor attention is this proponent
here it is 100% free and open source in
that it's just using basic Apache to on
a Linux operating system already HTML
Javascript and a bit of - even plus the
indexing where the local using elastic
search and that's also a percent open
source product as well so the blockchain
here reading the data here and then
there's multiple interfaces out to
different services from there so this is
the web browser search and this is a
optional third party things like
push notifications and so on we'll get
to this component in a little bit I'll
talk about this I bet so the smart
contracts search engine sits between
just a sits between the full note and
the data and its organizing Rossum our
contract data and the blockchain are
like event logs and so on and it's
providing essentially like a search and
discovery service for the decentralized
applications okay so this demo I'm just
taking some screen captures if you go to
endorse it instead there's a menu down
the left-hand side you'll see this
data-driven depths here this year we've
the first paragraph that links off to
some coding get up and this is HTML
Javascript and solidity smoke detector
and there's might be just shown us this
is the build tool that we have and so
you put the salinity code in man you hit
compile and deploy this so the argument
for this constructor here is asking for
an accounting so we put in one five
underscore double zero one that to the
chain and then what we see in the build
tool women click the play button in the
duct tape you actually deploy the front
end of your done so this is what the end
user will see and here we have this
account and I put a belly in on one two
three and we update the balance and what
it does this my quick search engine goes
and finds small contracts on the
blockchain that match so what we do is
we store the API and then we hash it so
we end up with a deterministic key per
API and so this my contract search
engine can go through the blockchain and
find all the contracts that match to
that key and so what it's essentially
doing here is finding accounts of
contract top X with different names and
it's trading the sum total of their
balance and they're providing that so a
smart
I can't do that to another contractors
they can't see each other's data but the
search engine can aggregate so just move
on to this part here what we call the
SSS and a-goin police come talk to me
afterwards because this there's too much
to say in ten minutes so this is the
easiest way to access all this if you
don't install or do anything with any of
these smart contract code or anything if
you just simply go to ESS SJS and you
just install that and then you have
instant access to blockchain data so
we're running if the remainder theorem
classic sophomores marionette saga miles
test net for the death train so these
are already set up we have some specific
premade functions here for your
convenience so for example you're just
esss your search using address and
that's the address and all return done
the next thing a specific thing search
using keywords so in this case that
variable name the account we put that in
as the dark and returns
well adjacent so then your phone can
pass this right that's a really
efficient way to call data blockchain
data and get that back so instead of
your phone having to get home there are
some records and look through the wallet
do decision making what you can do is
quite a complex query where you can
filter out so I don't want to see
everything in the last AR from this
address with an account name called
DEFCON and then you'll just get back one
report so it's really efficient and then
you'll find any active process one small
piece of Jason
okay so one of the reasons why this is
all right this because it's separating
out it's very flexible but it's
simmering it out the components so if
you have a friend developer that's a
really different skill set you can just
take them you know JavaScript and HTML
and CSS but what you do and this is what
I want my duck to do from the users
perspective you don't need to know when
they push the button that's going to
call smart contract functions and so on
just don't worry about that just poke up
the front end of the HTML Javascript and
CSS so it's enabling you to have teams
work together similar to the the rules
engine allows like a business analyst to
write rules and rules and hand that off
they don't need to actually be able to
contract the right contractor but that
same syntax will apply and just plug
straight in and work so this concept to
that you can create your own custom
queries you can extend on this to
provide like customer push notifications
you know triggering what amounts to
overall under certain values etc
and I'll pull it up if you're interested
in building your own or using hours or
deploying it up and creating the product
please get in touch and we'll help you
[Music]
all right so we have this possible to
challenges and parties
in the second abilities would have a few
stuff outside of the UVM so that the
mountains that they can flow out
[Music]
we impress LVN our foots on fire twice
to the heart and first of all because
elegant always just like a jerk
cc-come hell so it has a call like a
signal to us to see or rosto provide all
you can see yes they all will have
support in language to you if you are
not interesting with just
he want to use your fire
Alice languages yes in venues Albion and
the umpires
that with our BN if we want to define a
new target West in Pakistan tonight that
we have one we have yossel maybe if what
that happens maybe there will be the
Boston familiar with the EBS three or
four or five so Albion provide a
mechanism that we can very easy to
define a new target and this DC vendor
with your financial you don't mean to
have to translate your oscillatory
directly to the mean pocket you can use
the Oviatt because intermediate format
called lv NIR so every language will be
transformed into a unit your uniform
uniform language and then use this
language in two different objects so
this is a surprise as we have lots of
new partners or dangers of problems in
fortune for VN so when we just
integrated their way into the question
which M so the debuggers we don't
- its weekend during average of the
perennial VP or something like that and
the host parties well we want to talk
about more banana leaf love healthy
infant walk we can define a new cast
optimization skill that less can so we
can just modify each augmentation so my
style is more programming language on
IBM's and all proceeds will be be
translated library's certainty or writer
or Rasta or Cephas or any foreign
language they will be they will be
passed and constructs with the SBA heart
rate and funding which generates the
healthy IR and in effect we call you up
max are because we can add lots of
manager here some sniper can reduce
reduce the echo or again we can just
simplify a lot of addition or multiple
[Music]
current it's very easy in this photo
charts we only do what's the latest with
Madonna
Olivia I are with a native of Michael so
we can know every instruction in high
level the closer it is the closer is
like hunter - hunter or something like
that and we can apply lots of difference
here right here well we met in the
assembly center he was a non-indian and
back into AI also we have a cost amount
of here and when we have a problem here
we can apply the traditional energy
consumption issue the package of that
into this model and we had just apply
laws are the manifest engineer
and we get of Mulcair some Isis Michael
here okay so let's go into the demo part
I will show you how to use our compiler
to compile you as I recall 92 and then I
are finally 482 that you Boston I seem
for Evo parties okay so first of all you
need to come into love in answer to the
he wasn't has hands just like this and
we have these muscles you can keep going
as he attacks the soup I if you use is
metal he may detect a one hour the
audience so as to know so you can just
go yet they just run it and excuses
comment in our next eyes and together
I go so I see I think I can do that
already
so it's not enough
okay I know this best
[Music]
okay now I run the mansion of
srl demo and first of all you need to
create a comrade and we'll many endemic
opiates
Oh
so just press it as you can see this is
just 20 country and we have possibly
without pan sets and we have event
wealth transfer and here is a short term
you can sell the post buy and sell like
utilize basic bounces and also a budget
for the affairs of people careers and
families in such as crunching and if you
want to add the setbacks protesting in
the just include library and you see
it's a lesser that's fine but for the
diverse artists recommend when you use
as however you can can help making like
this and no worries because we all need
the compound is yeah
[Applause]
we'll be in compilers and was no
accident
we were so many cars and in welcome to
was final one is love one hi file called
cancer that was a novice the Ebro a file
called the country appointment and the
vampire you want to deploy light into a
certain he was a personnel was new just
back here and you can find it wasn't as
natural and
and just some your transaction because I
think this anyway to city or a remember
there and because you need to pass your
your your all wasn't to here so you need
to enclose this finer file into a stream
we have we have provide the coming here
just okay that and enter okay you've got
this this lots of string this is your
country and because it is very very
large so I need to just just scored our
my coming home
okay
and
my comments will ask you to confirm it
right
[Music]
don't worry we have employee of amount
of things before words also if you've
got the arrows of where you can retry it
simmer 5 because I have no idear when I
just write several nine there will
always be one or two
well success this we're the 40s you can
get your mutter here and listen to earn
your badges and you can find a Westco if
they want to know Weiss the use I love
the what while we can see at least
happen and also if we want to see how
our storage parables even kind of
storage have and you can find this file
and it was bet here this model that
shows our metamath to connect our wasn't
has met and just change to occur here is
your focus now you can't get pellets
vote and you will get you a balance in
here and you can transfer your your bath
and a hot dog and just by
[Music]
and any monitor
[Music]
but you need to see your semantics
all right
you know I think our time is optional I
don't even
anyone there's a kind of second sight
[Applause]
