[Applause]
or a tamale this morning how efficient
is how to box of Engineers blockchain
enterprise applications so the two of us
today we've got pal Peter hello
so if any of you are using some of the
cool stuff that we have my phone as your
inside okay okay okay I was out of the
Parkers so the primary by the wife is
not a watch something you would all the
cool tools that everyone can use about
me I'm in a different section of markup
for an unconventional software
engineering
they do so we go where are these
customers so what I do is I hope these
new customs going to be launching
applications this session is a mixture
of me going through some of the
architecture that I use sometimes I use
when I'm creating this enterprise
applications wouldn't we talk to these
I'm in across the mouth cavity
architecture remember - Cael he will
walk through cooling and how that can be
used to accelerate doing blockchain
applications I will flip back to me and
I'll cover up now that young and some of
the tunic looks Alec Eger
compose things together let's cover up
the one that I usually get like this
which is usually why the do we need
public and private blockchains
we have public everything should be
covered so come up with the oval ring
public aetherium we can't trust anyone
so because of that the security thinks
that they'll intro them all around
justice human if everyone is trying to
take us lightly so everyone is confirmed
the keys
in disgust yet because we diagnose to do
the bad act aside so everything has to
be security around that axis trying to
take these tools which is okay but what
we can solve a private network we have
different security considerations to
worry about and usually with the web UI
and application front end usually this
type of stuff is deployed else would
well now that's great bro
venison are great but I'm Shiva to kiss
you apps that's right both inside of the
enterprise space these limits reading
the February about enterprises think
that they have really really live
transaction volumes so they always say
the company the etherium public club
chains not allowed we want to do
something possible
so because we have different security
considerations we can relax some of
these things so we can go move to things
like approval Authority where we can get
some of its high transaction volume so
that's one consideration but it's
usually not the main reason that we end
up using a ramen change
the two main reasons I usually scared of
the other thing we're going to talk in a
process with motivated develop test and
they want to go to something
what chaining but they're afraid of and
they want to know publicly because that
so they want to have a nice safe space
that they can go deploy something play
with it get the developers through the
emotion of how to build these things and
then once I mean if you use on some more
happy go start moving into painting
space level of maturity of private
transactions a lot of the things that
they sent a positive doing a beta base
scenario is commercially sensitive right
now with public etherium transaction is
now there are things happening with Zeke
I stocks young have just released
Michael
they were looking at logical to coding
integrate thoughtful into some of what
we're doing but as it is things the
three main reasons why we need
everything
yes there people at a private enterprise
network look like this so instead of
having unknown actors we've got a profit
or Arbitron so we know garment bag
design we can relax some of these
security considerations just a little
bit so it goes from heaven trying to do
this in a trust us this implies way to
more of a we go and use a blockchain to
the shared source of truth so understand
that right now business applications so
to me that's another reason why we do it
like this
they have it three different
appointments each and a processor and
because although they're gonna be here
the pump go hey we wanted me out to
track these widgets more efficiently
between us
[Music]
application
now that's a while I'm good so typically
happening that's what happens when I get
caught in is we talk to the enterprise
and what we ask them do you know about
blockchain that was good yeah yeah I
read Forbes magazine under all about the
options and so because they are a large
digital enterprise of got all that
legacy applications created so those
used to go as traditional multiplication
so if we go with typical there going to
be one really large company so making
these of not let's just go with Walmart
everyone knows that and supplies to for
money so typically what what would
happen
Walmart the largest player in this place
all of these supplies are going and
supplying packages to them but because
we'll have to be playing if they can go
dictates of all of these normal players
what are you going to log into our
front-end web portal or if you go to
update to them so Walmart in the back
end and have their business here but got
the image here with database their
traditional degree to application and
they might have some analytics reporting
or something
so because of reading couple is in a
legacy enterprise infrastructure
that fable there you go we want to make
this more secure but making a blockchain
instead all they do is they take that
data bit and they replace that with
watching they go now all secure that's
not watching and we tell them no you
just made it work you made it
taken the worst party boat so all of
them got now is it exact same
application which is now a whole lot
slower than what their sequel database
cool is it and then think yeah sorry
everything is now a few minor firewall
so none of these parties came to access
that watching so I asked him so anything
who wasn't going to post this blockchain
no one we control the blockchain it
doesn't work like that guys so then we
say okay so if you're not going to even
let them host it and
have I had direct time and points of
change that I can leave serve my own
limits behind a firewall so you guys are
right a blockchain your your reign the
blockchain you're the only one who's
even though and it can be kind of
firewater not access so you can't prove
anything because right now it may be
secured in a blockchain that they can't
tell because whenever it comes in
transit it's doing modified in any of
these deities before it gets out to here
and so the biggest thing that the
biggest challenge we have with
enterprise is that education around
every every single party has to be how
to access the blockchain directly to
verify it if you still go through a
centralized access point like this and
it has absolutely no value there's
always a deep trouble because the light
is playing here but wants to still look
down and control everything so trying to
get them down
you can't control the blockchain
everyone needs the festive that's
usually a scary important so the common
mistakes I usually see what we do so far
they have a 3d application they're used
to they are they want to control
everything propose everything for the
industry they want to use a block
transit database to try and get them
moving with their bare hands get out of
we have a database that we control - we
have a shared state for shared
understanding between all parties that
speakers might shift but once we get
through that usually takes about two
days one speeding it with interest and
you can see them get excited with now
they understand and it would still be
problem why these company
so how do we go about hoping to educate
them if they're to go that much changes
the source of material so it's no longer
your Bacchus systems are the source of
truth one isn't the blockchain is a
slice of truth which again another
mindset might entice kids understand
that yeah that consider going to react
what has happened in chamber Oracle's
and again it's another mindset shift but
you can't tell them nothing's confirmed
we've sent it into the shared state this
headset is updated and has come back to
buy an Oracle scheme and a potato you
will back into your recording systems
this one is from what we've seen on many
projects file would have one party one
company inside of an industry say we are
going to go and create D blockchain for
supply chain D block chain or Apple Z
table tank whatever so every time we've
seen one comfy say we're going to create
the blockchain and then we're going to
roll it out to our partners if it's bail
every single time I've never seen that
way why don't we seen it work is when
that they get us engaged we'll go in and
we'll say what are you going to be
working with you you bring in at least
two other parties for an expedient to go
in then we've got at least three
companies are going to be part of that
initial development that initial
deployment it was the same thing a lot
more successful because that's what we
do have three companies to businesses
into the development it's been employed
out to their three - your subscriptions
to the kids rolling and most most
importantly it's every time a teaching
them it's applicable to public watch
chains so everything we're teaching them
around key security around app
development Oracle etc works inside of
the private space but my super defenders
to get the ball out steals that wants it
happy within the b2b space that can take
everything that's at learn to stop doing
things in b2c public aetherium so we're
talking to them around sure we could
have a private network but why don't
make the plasma chamber so sniffs the
public networks we can do some more
things easier from there so to change
the conversation of plasma change is
working well so
once we've gotten past that point and
they were talking about architecture
there's a few little pieces that we use
so I'm going to go through some of the
service pieces that I usually use I'll
click over to help repair my own bunch
of stuff then we'll go back to me too
but to connect the glue between the
blood change side and the traditional
enterprise of Champions
so we've got two of them which are
service based programming we've got as
your functions which it is function of
the service so take a piece of code and
it will run into service style
absolutely that's great
we've also got logic apps logic capsule
code on the screen in a second so it is
serve Allah screeches but you don't have
to write a code you can just drag in
building blocks and then the last one is
I've been through which is an enterprise
pub/sub so that's a great way of
publishing make something happen in the
blockchain come on out to the property
event group and any back-end systems of
care that something happened in the
blockchain we can subscribe to those
events and then do something to update
the reporting
so we use so these two and then so
between these two if we have to do some
tricky custom stuff in his function
anything simple we should just go to
logic absolutely get it done in 20
minutes so logic apps building blocks
you quick and grab things on there so
it's great because when we jump to an
enterprise and we go down as high as
demos in two to three days by using
plus we just have when it's not fun
after that happens so like an Oracle
sit down monitor when something happens
go and do something this place in animo
so anyone to do one of those hit go and
out establishes these what happen X's we
can do a few things we've got triggers
so like Oracle's when something happens
so we now have fabulous codeless
Enterprise marbles it's pretty cool and
action what to do or something
in trigger deployment we can trigger
executing a functional spot contract we
can do the cola transaction and probably
throw about cycle tracks what it looks
like if you want to read or write to a
blockchain not usually this so what I
love to win the develop it about with
new you teams I get them too so that
takes them a few minutes but see how do
I want some that who can just go and
enable them to go trigger these after
this dragging the endpoint click drag
gonna pull this moment reddish gray to
HTTP response passing that context of a
place so that kind of that five minutes
that was reading writing and then we
have those service articles so just
things business my contact
address select future if you want
just got that from the API and instead
what you want to do go and see without
advice publish it out so yeah they
talked a little bit about developer
experience and one of the big things
we've been doing there is some pseudo
code so improving developer productivity
making this a much easier process for
you know new users but also I'm not
trying to get into the way of advanced
users so somebody who knows what they're
doing with these tools we want to make
sure that that still is frictionless but
we want to break down the walls for like
new users and somebody coming into the
sometimes not quite as approachable as I
think so looking at the current
developer experience you know there's
obviously some a development component
there as David mentioned things like
writing smart contractors your back but
a little with that then becomes the
second block which is a huge kind of
area for a new user to say what do I use
to build this back if anyways we've had
that with other frameworks and
programming languages before but one
change specifically a very open source
at nature there's a lot of awesome tools
out there and there's some things that
maybe aren't so awesome right so people
trying to find the right tool for the
right job has been a struggle we've seen
a lot that people use in these so one of
the motivations for even getting into
developer experience was can we improve
that process make it easier for people
to get their job done and then they can
grow to enlarge as a building we
subsidize the second thing when we hook
this up to infrastructure so if we're
just playing to a public or private note
we want to break that that wall down to
a lot of times we do these hackathons
early in the last few years and I can
tell you that we're the stumbling blocks
happening not coming up with ideas and
get the things that we like how do we do
a transaction like you know everybody
knows the theory of like that this
happens when the rubber meets the road
and they have to use 1/3 chance or they
have to use some of these tools they
start getting confused right away and
then you know they start to fall apart
and English
activity and so one of the things there
was how can we connect these Ledger's
and much more sequels fashion and then
also to open the deployment so as you
are starting to put new things out there
people are starting to be used to
beautiful smart contracts and
transactions how can we help that
process as well so that's those are the
main motivations for why all business so
from an integrated development
experience if people look at the left
side of this and then move to the right
on the left side basically are saying
like in most languages and most
programming structures that we have we
have the idea of a create your project
right not just a hello world but like
let me scaffold out a real structure
that I would actually use I don't want
just one something example or something
like that just wanna get started
creating Ledger's how can we do that
from inside the I mean we don't another
issue that comes up is there's a lot of
different service providers as a big one
but there's many other ones right and so
it's like okay I need a ledger after I
create my stuff then I got a bounce out
to it website another Facebook there is
my productivity right so you know
keeping someone engaged in the IDE is
really beneficial for the programmer
that stay involved it's a like if you
want to go to deploy this okay I keep my
same mindset if I start context
switching I got issues
and the automatic configuration as I
mentioned before so we want to take what
we're building take wherever it wanted
to and help build that configuration on
the fly for you so you don't have to
like waste your time with configuration
files certainly they're there and you
can go sweet them and wait easy but most
times you just want to get through it
let's get this thing running that
seemeth broken and see how I can visit
you through the middle of the IDE and
part of this is like Microsoft and you
know bringing our OEE like that Visual
Studio best example is one aspect of it
but trying to like take over this market
and say we're going to build the best
debugger we're gonna build the best
packager this is not something that's
going to happen right because there's
such a huge community around this that's
building awesome stuff and so really we
see ourselves as more of a connecting
tool to say who are the best guys doing
these things are who the most popular
ones that we can work with and get them
if there's something bigger in there so
that we can build a better tool and so
in this case one of the first ones that
we worked with was truffle a great
relationship with tammand and a group
there we work very closely with
consensus and code with Blanco we work
very closely the very foundation on
remix and there's others that are
imagined tears that we've been actively
working with the foundation to bring a
more of the people building
tools in the ecosystem so if there's
anybody in here building dev tools
certainly come see me at the booth or my
group and talk to us because we're very
interested we want to make sure that as
we're building this toilet we're doing
it in such a way it's not like tightly
coupled to one of these kind of
frameworks we much rather it be open let
people have choice I just help the user
get started and then at the right time
is basically the ledger technology so
like after we built something that we
have a skoy you need to actually do it
what we're we deploying these things to
certainly one of the things to get
started and if I'm on a plane or if I'm
disconnected I want to do something
local I don't have to go spin up a huge
Network and waste a bunch of money just
to see my smart contracts working
functionally my automated tests are if
some of the other vendors were working
with MIT backs some of the security
vendors we want to make sure that it's
all working when we can test that stuff
on local dev before we even want to have
been changed to do something whether it
be private or public we mentioned a
private consortiums Estonian eyes
tightly comes to Azure certainly Azure
is a nice experience in here but
certainly you can also plug this into
existing notes if you have them running
on premises or something of that nature
so don't think of this I did hear some
feedback people say let's go - you're in
there that scares me you know somebody
defiled Roger as you're just a great
place to run your stuff but if you just
want to run this stuff local there are
around premises as well and which raises
to the third box which is a
we announced in May has your blood
change service so don't take away if you
don't know anything about this we're not
building a ledger ourselves so this is
kind of like quorum and essentially what
this is is for some users as they I
trust you enough so that you can run my
notes for me just front windows for me
as a pastor as opposed to me having a VM
that I have to maintain there and
manager can still do the VM stuff so
people want to have their hands on all
the internals and make sure that that
works totally fine you can run that this
is something that's a little bit faster
so maybe you can even use it for dev
test certainly introduction people want
to use this because there's a highly
available solution here so basically
we're making sure those nodes are
healthy and running you can think about
other services who do something similar
where there is steam in it for you this
is Microsoft version and then on the
public side you know we talked about
this because we don't want to build any
barriers in here certainly Microsoft's
bread butter is enterprise and having
these big enterprises engaging
blockchain technology but we also don't
want to sever off anybody from the
public side they should also use this
tool we want to make sure that it's
amenable to this and so on the public
side something we're launching this week
we haven't kind of talked about it yet
is that we're going to tiara so we've
been working with them for some time
what we wanted to smooth that process
not much more from
so I'll show you what it looks like from
the hazard walking service
Charon is nearly identical so
essentially it's down to the couple
clicks and you can have yourself in fear
without having to jump to any other
website even if you're new to in fear up
public networks and I know there's only
winners we've been talking to as well
who also in this work with you guys to
of course the architectures bill to
cover you know no providers into that so
this is kind of like our honeycomb as we
call it which basically looks like the
stickers on people's laptops but
basically just the the key points I
wanted to kill and I hit on some of
these earlier but just hit on most of
them and we have the the answer market
service integration penalty project we
have all those language defects and
Lenti compilation of those things
happening we have a debugger and built
in there is you can see that as well
I'll show you that any kind of different
changes you want to deploy to working
like everything from the for tape so if
you guys are familiar with our
chocolates been doing in that space this
is pretty interesting so you can have
your induction environment which could
even be public watching or it could be a
private when it's in production you
essentially for that change make your
changes to your code tested yep
everything's working destroy your form
push your changes either public or push
to what automate that little bit more we
definitely have to so the smart contract
test execution I've mentioned some
editors were working with their once
their workers would like some walnut
vendors as well truffle is one of them
we've been working with them to improve
the truffle HD walnut experience all
support us is another one that we're
working with it was base to improve that
we also have these like logical
integration they was talking about some
of these server list things I'll show
you what we basically if you build smart
contract anyone like interoperate with
it we have a contract interaction we
call it which basically built a you will
have apply for you of adhesions to test
your contract and certainly playing with
the decedent's working but then on top
of that you know I want to wrap that in
a service function so that the functions
are really these logic active functions
are really just like crowd operations to
a blockchain producer we want to set a
transaction in we want to read some data
we want to react with the but it's
pretty basic so what we did any BS code
was said well if you build your smart
contractor we know what methods you have
it there so we can basically we have to
have with a lot you guys give you that
as an output you don't have to write any
code you can basically pop that into our
logic app service developers what we
call them someone who doesn't write a
lot of code can even use that because
it's basically like connection they're
super easy then the extension and this
stuff definitely seems to keep up
finding it but it isn't our traditional
studio marketplace watch later period
you'll find it this is a short link to
it
we launched this back in May
get feedback it's all open source you go
look at our turn up their monthly bills
right now and publishes like I said this
week we're doing one I'll show you some
another vendor we're working with so
we're gonna we put some new stuff in for
this one today and then also this is
just the experience but we'll walk
through that second and puppet to
actually do some work
[Music]
okay so let me pump into a pressure
console here so this is just three BS
code on the Marx Brothers are getting
started if you just go down low just go
just go straight for it when you come in
here you can search for these miscible
no extensions so these are things that
meant you just type it won't change and
you'll find better here and so basically
once you have thought you'll see this
little over here now I already have one
pre connected here this is one talking
to a sure but also explain what that is
in a second
I basically opened a foreword here it's
just empty right now and I brought up
the command palette man palettes like
basically all the commands that we can
do with these tools then we can add new
ones to it but right here is what we do
right now so we have our founding
project I'll show you is about the
transaction flow we fully integrated the
debugger into the IDE so you can do all
the step through step out of you can do
the inspection and now for the
instruction level you can see all the
there we do the deployments the bills in
all the compilation that's happening
there we can connect and create new
networks up here I'll show you what
those look like
we have some things for key management
so if we basically just do a new one you
can see when I do a new project now if I
was a user that doesn't know what the
heck I'm doing if I just keep hitting at
her I'm gonna get a nice scaffold in our
project I know what I'm doing and I want
to go I said to hey there's truffle box
I want to use it something like that I
can do that as well so in this case I'm
just going to take the info guitar the
compliment put it in the same forward
will pray to the internet gods here the
network is not great here but that's
okay I have the cookie demo in case
there's mail but basically what we're
doing here is we've created a template
if you're familiar with truffle boxes is
one package format that we're using and
so basically be scaffold about it but
the right stuff out here for what people
should be doing with they're doing one
of these so we have a basic project
structure you have like compare all the
normal stuff people would eat and then
basically you can see as it went through
it just went pull this box down it's
already developing local tendencies so
in our case we're using wallet so we
needed a salsa with no dependencies so
when you do this yourself you see that
it kind of hangs here as it's doing
something what it's doing is just going
getting all the packages that we need
I'm doing it for you again you
customized about the terminal and do it
every two here if you're into know and
know what you're doing with this stuff
but if you don't know what you're doing
is what
it's a good state so just give that a
few seconds here there this so as that
finishes basically we have our hello
world we have our migrations I already
have all the migrations set up for us if
we look at our truffle config minimize
some things here we automatically
through a development environment they'd
appear for you
we have ganache baked into the IDE so if
you don't do anything else it'll
automatically just work in a distinct
obsession
we also inject the part where provider
and the HDL provider and you'll see what
that means here in a second when we
start talking to other networks so the
first thing you'd want to do is just you
know do a basic build this is in preview
so you'll see lovely debug commands to
be continued to minimize this but we put
this out here so that people can see
what's happening there in case there's
any break so that it is cooling while
we're in preview but basically you can
see interested in compilation projects
and then if we do a deploy and notice
what we do at the point we basically get
this little drop down here now what's
cool about this you don't get was you
can see it says from truffle in PJs so
basically in the trouble config where we
had that development by default intended
for you
but you also want them to trigger
because I already have one register so I
think go up more
if you're listed over here you can also
do local networks and things over here
and again too many audience who are
working ledger infrastructure would love
to blow you guys they can as well
architecture is very offensive and it's
basically extended and then they
basically show through user just as a
choices so again they didn't have to do
anything they didn't have to go get
Marcus Ian points and figure out like
how to authenticate for this thing
that's happening for them I'm happy to
talk through that in detail if you want
to come by the booth I can tell you how
we're kind of doing that securely to
make that work but for instance is just
go to the location on to say I just want
to do something quickly because we're
going to try this out so you can see I
do my deployment we can see our logs
here and we got our build floors
everything came now
now the next step you said was well once
you get to this stage you know 30 users
or look like well that's great like
everything worked how do I like work
with this thing I didn't build an app
yet I just want to like work with it and
so in this case they could drop to a
command line and do that then they're
gonna have to go read and hopefully they
know how to read and they will read but
you know they're trying to get things
done quickly so we say okay we created
this contract interaction page minimize
some things
is this a react application that's
inside here that basically is then
reading our contract so this is dynamic
this knows what methods repairs the
latrine methods in my contract
request said response five has the
deployment so if I do multiple this
drop-down list will fill up it also has
a bunch of metadata like where does this
thing get deployed to from all the
address detail you can copy and paste my
code and API if you need them and you
start building your application so we
thought that might be a good thing and
then you can actually interact with them
so if I set a test request by executed
you can see the state filled up I'll
show you in a second and it's not
smoking mirrors that actually went to
ganache right now and we will do that as
will do a debug but it gets also seen
you could get a response messy response
you see that was filled in so this is
basically showing the state and these
are all your actions that are inside of
there
like this is not smoking here so we pull
up our command palette you can go into a
debug transaction if you look really
closely maybe you can't see it in the
back but we give you a hint
these are all the transactions that have
happened recently and you can see there
this is set response and this one was
send requests that you snip those two so
if you click on this basically launch a
debug session for you will commemorate
everything back here at the transaction
level but we need all those details you
can expand this stuff to your heart's
content to look at it if you start
jumping in here with your function keys
as normal you'll see a percent response
that we actually called there you can
see our response message we can cover it
and see those so really nicely debugging
interface it actually breaks down even
into the instruction level as I
mentioned before so if you're a public
developer you might be be concerned
about you know what's happening here
their store calls have you can see all
that stuff directly
so we think that's a pretty nice thing
for users who are like trying to figure
out what's broken in their contracts
really quickly in Chinese so we jump
back to say okay our typical flow was we
we did something locally there we've
deployed it everything seems to be good
and now now my case I already connected
to an Hydra blockchain service how I did
that I can connect to or create a
network here so if I say connect to the
sand dip your manager by the way this
week in furor will show up and hit drop
down as well so the same experience will
happen from Europe and then basically
you can pick your subscription in Azure
it's very context sensitive to a
subscription in the resource group
interfere and but basically list your
projects here I mean you can pick your
project up there get your horse back in
this place it will see what consortiums
up there in my case I've already
connected that one so I could create a
do it you know what I'll do everything
for me I don't even have to go to any
other portals or web sites it will spin
up that consortium for me it takes a few
minutes so we will do that right now if
you expand this you'll see that we have
a context of a sure we have our
consortium remember our transaction node
if you right-click on the transaction
and you can see we get to our PC address
again if you're building an app you
typically need a like as soon as you
start like writing JavaScript code or
something like that you're gonna need
that you can just grab this and put it
right in your clipboard you can use it
get all the disconnect if we do not
using this consortium anymore they'll
still keep it there we're just basically
disconnecting from it the exact same
thing happens with the pure except for
and wish I can show you here but we're
just publishing you're actually right
now
but it'll basically show you all the
gnomes underneath there for the
different networks whether it be rock
scene ring be you know main tent those
kind of things same experience and then
basically whenever we go to the puddin
that it's the same process so once this
comes up one deployment we would pick
this guy and you'll notice in this case
whenever I hit a network it's not local
I need a mnemonic so I can either
generate a new one here or I can use one
that I have existing which is here on
disk
so we initially give you some feedback
here initially we wanted to make this
super easy to get free users to say I
don't know what lot is they can generate
they don't open file location' things
but if you just be drawing or wherever
it's gonna get enough like from a
security perspective so what we've been
doing is working our HD wallet provider
so that we can provide two options one
is have this encrypted file wherever you
want to put that thing the other one is
you know real HSN so families just have
an azure there are others that we exist
out there but basically you can choose
to use an HSM to hold that demonic that
secret so that they can't get
compromised just something we're
actively working on but if I put a
pneumonic in here and I look at my
output window it's a little bit slower
because
but it will eventually push this stuff
you can see we say they're going up here
and even C is a point to a different
network here and eventually that will
complete so just make it super easy I
don't have to write any code any
migrations and I'm able to live employ
it directly to other chains you think
that's pretty cool here now another
thing that's while that's finishing up
on this menu
a couple things one is we just talked
about these Falacci gaps so this bottom
menu section here is basically covering
those things so far grapple in these
contracts
in a server this application I pick this
I think what I want to do blow up at
your function I'll give you a link to
the documentation you can look at how
these things actually work we would put
a contract address really so don't look
like
I'll go big with him for now
and it basically will pick because it
and you can see it generate a logic
addict now what's that mean it basically
generated a bunch of JavaScript for me
it already prefilled everything in
forecast but basically it looked at all
my methods looked at what state Berenice
exist stuff and they created a wrapper
for that and basically put that on the
jason and i conversion that now but it
in my source control engine they can
take that up to Azure and it will fill
what David showed you on the screen
before those thank you we don't build
that automatically for you so makes it
super easy for people to build
applications whether be event based or
crud like I want to read or create
something inside there so the other
thing then immunity you might have
notice whenever I was going through
these menus really fast was in your
contracts one of the things people want
to do is language suck this stuff's
already consult great anybody they have
a pretty nice set of libraries up there
that people typically use for our
production applications that have been
fully vetted rock-solid contracts for
different things and so we said how
could we improve that experience right
so the typical flow we saw with
enterprises was I'll go do an NPM
package go ahead and pull the opens up
in contracts the problem is that we saw
with some of the customers was pulling
down everything like I just want to do a
TRC 20 or an e or C 721 all right see
some math libraries I don't need all
this other stuff so I have to go to lead
it and make sure no one
p.m. installs and that was stuff in my
directory that I didn't really think we
were talking to the Zeppelin guys about
was could we create like categories
similar to what they have under folder
structure that selectively allow me to
do pull these down and then resolve all
the dependencies for me so if I just
want the mass or the lifecycle stuff for
me access to stuff I can pull just those
I'll show you what it looks like in here
so what this is actually doing is going
and grabbing a specific version of the
open some blood contracts and it pulled
down 15 files in this case and I'll show
you what they look like but it also
gives me this little more detail so you
can click one and this will take me
directly to this rich documentation so
if I'm new to here see a plan of what
I'm doing I can come up here this will
walk me through everything I need to
know about what I'm doing with that a
couple other things that were doing
there as you see it down little contract
immediately it resolved all the
dependencies for these things so
anything that's you know these things
have multiple dependency
to each one of these so that's happening
automatically it's also making them
read-only so one of the things and in
talking with open Zeppelin was you know
sometimes people in inverted leave make
changes to these thing and then that
you're going to introduce a security
problem and that's not good and so said
well first off we could make read-only
but that's not good enough right because
somebody could just make them not
revealed so what we did is look at the
actual commit hash and at the final
match up and get up and so we know for
sure so when we do it limit we actually
check that instead like every time
somebody doesn't want to wear this we
actually walk it right now and say
someone changed one of the core
contracts right here is the one that
they changed go fix it thinking about
tweak that but the mockolate of linear
shared is really good that she's using
parents as opposed to changing those
core contracts and so we want to kind of
make a firm stance there to make sure
people don't pull over leg off you know
with this kind of stuff so basically
this will automatically do a
verification check now every time they
do an employment make sure that don't
change season and I can started studying
that it also created the migration for
me this kind of cool to it like we went
looked at when all the dependencies
aren't built in the KT migration file
for you so again you don't have to write
any code if you just downloaded a T or C
20 and hit go it will take care of
everything and migrate it for you I'll
just be totally honest there's a couple
breaks in this as a brand oh and some of
those are around like some of the
contracts actually need parameters to
initialize themself like I didn't a
constructor or something and so we're
thinking about a better experience for
that happy to hear feedback from anyone
here too but we're thinking about
integrating that as well to say hey in
order to using air C 20 I need to know
what you want to name it or what the
supply is or something like that then we
can prompt them for that and then do it
for them
they don't have to dig around inside
these contractors and so I think that's
pretty much all in the show I'm happy
that afterwards we can talk through
anything here and I'm happy to talk
about the eternal darkness ugh how it
works
like the new stuffs coming live this
week so actually in process right now if
it is publish and this will happens that
one stuff in it
as well as the carousel and this
ascension works on Windows Mac Linux
yeah those three
so that's something important when I
feel at work for these toughness Oh
usually have a bunch of half of this in
the room we'll have those laptop and a
half we'll have Mac laptops so being
able to have everyone using the exact
same visual studio code tooling with
these same extension makes it easy for
all the devs to have the same so beyond
just like scaffolding stuff that we put
up here today there's also this thing
and people sometimes get confused
because we're portable and who thinks
it's okay hockey tournament so basically
the answer Joaquin dev kit part of that
is this Visual Studio code extension but
another part of it is this github repo
there's open source code examples up
here a much more advanced stuff on
server functions there's a lot of
documentation helping get started to all
that stuff so once you get beyond the
initial stuff that you want to start
diving into more complex flows something
cool to look at the other side was last
ethereal other one matambi but before in
Brooklyn we actually made a first
Balinese project with Microsoft actually
hundred and twenty thousand dollars
worth of Alibaba and basically what we
did is proposed out twenty different
projects for people to work on to build
different things using our HSS using
some service functions and there's a
whole slope for some around gaming and
tokenization and basically those are
fair as well it was super great
responsible
and I worked out really well but we
basically have this community-driven
section now too so we have the Microsoft
samples we're producing we have the
community-driven ones that were kind of
vetting working with the community one
but happy to take for contributions up
there if you guys on either side forward
busts are welcome anywhere I elect
you're here
okay so for the last 15 minutes I'm
going to get everything that we've
talked about and try to remix it to a
fingerprint we dive in and everything
that doula Custis is exactly what panel
to show you
so we showed them from the beginning how
to go sceptile sceptile down a brand new
project I don't learn how to add in a
few functions into you there's my own
tracks
show them how to debug cataract unit
tests by 8 - the champion testing it's
been through that again it's a getting
what we've done in the blockchain blew
it up to what's happening in the
enterprise so I've run through how it
works for single men million Cybermen
sodium then we go zoom out to see how it
looks when they come all together so for
one enterprise we used to have to go to
all the writing of unit testing
debugging all that stuff so doing that
locally I've got this is bad watching
so public love chamber start doing
things so that the back that's Purdue
Cal is talking about with this crowd
so if you look at those logic maps so as
Cal showed so I used to go and get them
to do a backhand because I may need to
apply drag in visual designer better
scale showed you now it takes ten
seconds now just right difference by a
contractor site we've just generated for
me generates out that Jason but we still
find that much capital we you can just
go and copy paste that what's your path
Jason file happen to add your band now
have your service properties to go into
the blockchain but once you've got that
then in the custom style
intranets go and the enterprise dips all
I care about now is that I kind of rest
in pointing the rest endpoint to go and
in terms of reading and writing looking
into the transactions so there are
people we can do around locking this
down to a configuration so accesses but
hopefully use this is a standard
question points along about which is
which is and caring about its money
transactions so we do a little data sign
of that
here that way if something happens as
though we go and step down but that will
change
whose kid including the stuff passion
function
perhaps I think how we showed how you do
colas service we've got this and why
that's a good reading a binding site but
if someone else goes enough to watch
chain we have to react to it so we have
the adventure of the stuff in the other
side
again is that that was that I'm service
article from a sailor star who pushed it
to an event grid an event grid what are
the kids back enzyme subscriber three
cups up
so another member updates the borman's
for widgets and the event comes up here
architects it publishes it event update
evacuate sickle cell we can update how I
reports that for you we go
and figure out to go start construction
constructing widgets for something
twisted so this one his price can go to
website one it's inside of a
infrastructure but because the house and
looks like this
so what an approx will pay plump but
because of love shining that cheers
thank might expose the truth
Apple the other Enterprise is just
reacting have whatever backend systems
if they want to buy as long as is
everything what's wrong
I'm so the kid might that we gotta teach
them about this is it's over everybody
remembers what was yeah we're gonna go
ahead
a way to say happy to see so they can
still do what they want to predict
management of their articles etc but if
they're doing a Big C app they can still
have a continuous unattractively so that
we can do it in two different ways the
first way enterprises usually want to do
it is it was forget the past this point
is to usually want to control like these
for the users so many paths of mobile
apps etc the
[Music]
can go for watching cat go in switching
transactions updates etc but the keys
yeah so that's probably going to be step
one as we get my crack these in a
process across the state getting about
more confident and then hopefully also
get up to something like this in a
process to have a whole day of stuff as
well so again everything with teaching
here in many show that they could
enterprise dancer also to public deck
tips so once we start getting closer to
you Robles and adoption that means stop
happening for
so how'd it go at business so if you
closed they should use before that's
these like anaphors and as your
blockchain says have some right
mechanisms they have but how to good at
magazines like what if I went around
that but also on the development side
now this word gets trigger that we've
actually released a white paper around
how we work in the Microsoft
so you have three companies three five
ten companies working together and this
want to show you how do we good and
manage everything around updating your
small Skoda updating spot contracts the
point about I've got some things rather
dip around there they're all dead so we
can do things live in southern Asia
DevOps whenever we have a fuller
questions we can say that we need to
have an agreement on each of consortium
members before that question
thank you moving pointing that out we
have multi-seat bullet so that each of
the consortium ends have to go and sign
up before
[Music]
so a bunch of life examples but he is
one which is he local in Japan so here
at Japan were working with a couple of
company and some to Craig and even
saurian we've got Japan Rockies is a
both a nation services some insurance
companies
so Johnny here's namely the ability of
the service kind of Hope Commons get the
point our R&D but they've go through
multiple different disasters providers
as some of you may have seen while
you've been in Japan you may have to go
to Japan ravishing fenced in maybe take
you underground gentle to a bus so the
idea here is about having one system
spend abusing and so the best prototype
for this we got up to money got me three
four days but we're using the best
Korean intentions
the scaffolding out all of the civil
patients here you can see here megabytes
and Japanese but the only ones of tokens
the icing seven to one tokens who are
just using industry standards open
Zeppelin to go step up works out for us
we're using the service Oracle's to go
to the technical things were happening
update report so we can show how
the tickers etc so there are many places
to go and bash up these things so here
we've got you need to connect between
these are home base traditional back-end
systems so that's got the open banking
HDI - and the customer accounts so how
do we go and take that in with what they
sew in weave those simplest applications
to allow customers to think something do
something do something service which
goes and updates the SE $20 attended
cetera so then we went back and then in
another four days we went and smashed
together another Houston our race so
again we've got more as in 27 to one
happened
but in everything we're doing here is
helping make sure it's all blockchain
fundamentals but for example malkia
around management so looking around how
can we do this with the centralized
identity but we wanted to make sure that
these as well so I'll be very careful
with what I've said because this is all
still ocean but that's a picture of that
picture is in the official press release
um let's talk about
talk about
so that was one customer example I'm
sorry to show another way that we can
smash these up so another way to match
these up so actually we doesn't dispense
intelligent customers now because high
high frequency item data coming in so
for the IOT devices sending in millions
of transactions per second half we
handled a band security so we obviously
have a million transactions a second
into a blockchain so what we want to do
what we call an end up citizen
these transactions turn out to the
beautiful beautiful ball storage which
is right well still a Samba subscription
this is not try to deter I could still
want to buy while it's in transit rabbit
so we periodically wanted to the
beautiful gorgeous happy change so we go
and every minute or 10 minutes or
everyone I'm going to take the hash
among those millions of transactions
which is sitting there I'm gonna anchor
that into a blockchain somewhere so
we've actually got an to read up on
stream github
so we've got pictures etc but we just
did this quickly with Rio together next
month marks up we're doing a little bit
channel hackathon so I'm gonna get a few
people to it could be said we would have
this documentation a little bit nicer so
what have some better Quick Start Guide
today
now all the stuff that you show someone
really importantly kid so we did this
same talk in truffle color so the link
there is chunk of 2019 so if you've got
a cage or ms / truffle 2019 you've got a
lot of the cool things that I just
talked about here anodized readme file
so we've got everything got up
and four tenets of law changes
development pretty pictures that you do
some information about what connectors
are links to the vias code extension or
sad cetera
so that's the important work that now
with that so it Microsoft we do have a
three-foot hole settlement placement the
biggest about their ticket so you could
answer the basic you can get it talk to
we get into the basement
[Applause]
