so I'm gonna be talking about something
a little bit different today as Jesse
mentioned my name is Taylor Goering I've
been working with the etherion project
for about two years now she's quite a
long time in this space I suppose I've
been doing a variety of things from
server administration to working on the
website I've helped with the go client
on Jeffrey Wilkie's team I've written
some blog posts I'm active on reddit so
you might have seen my name around there
a bit but I'm not going to talk about
what we've worked on to date so far I
want to talk about the future and where
athyrium could bring us in 2 4 5 10
years there's a lot of interest from
enterprises out there and although the
public block chain gets a lot of the
spotlight in the limelight I think there
is a case to be made that a film can be
used in an enterprise environment not
just for removing trust and removing
intermediaries but I think in a general
sense as technology stack athyrium is
really powerful so the things I think
that it can bring to you your
environment if you're an IT manager or
an executive basically my cell to you is
that a human can increase agility
reduced risk and lower costs so really
the first question is do blockchains
have a role in the private environment
to answer this we really need to
understand a little bit more about what
is a block chain where it came from how
we got here and to do that we need to
know that bought jeans are really a
culmination of prior work Satoshi didn't
just come up with this randomly one day
all this magic boom there it is no it
goes back to the 70s ralph merkle
inventing Merkel hash trees patenting
that in 1979
we also have distributed hash tables
became really popular in the 90s Napster
was a big way that this kind of made it
into the public mind chair and
eventually we had the proof of work
system which as I read was first kind of
developed around 93 and then finally
formalized in 1999 and these three
components are kind of interesting in
particular in certain ways the way I
look at it the hash trees are
effectively you know this data structure
that the blockchain is built on the
distributed hash tables or dhts is a
kind of this networking component and
finally we have this proof of work thing
and this seems to be the most confusing
part of it all what are miners what are
they doing people kind of call it
validator sometimes in some circles this
seems to be a huge point of contention
that only proof of work can exist but
even with an etherion we're trying to
look at solutions of proof of stake and
kasper and so forth so that's great
you've told me what block chains are
made of but what do they really do now
when I started thinking about this it
kind of reminded me about the scene from
this movie idiocracy really fantastic
movie if you haven't seen it wasn't
terribly popular but hilarious in its
own right and just to set up the scene
for you a little bit the main character
is kind of trying to explain to his
colleagues that putting sports drink on
plants will not help them grow they
don't quite seem to understand why so
let me just let you watch this and maybe
you'll get the idea what's killing the
crops is this Brando stuff the Broncos
got what plants crave it's got
electrolytes so wait a minute what
you're saying is that you want us to put
water on the crops yes bladder like out
the toilet well
it doesn't have to be out of the toilet
but but yeah that's the idea but
brawndo's got what plants crave it's got
electrolytes okay look the plants aren't
growing so i'm pretty sure that the
Brando's not working no I'm no botanist
but I do know that if you put water on
plants they grow well I've never seen no
plants grouted own toilet that's good
you sure you want to smartest guy in the
world yeah okay look you want to solve
this problem I want to get my pardon so
why don't we just try it okay and not
worry about what plants crave Brandon's
got look thanks Dave yeah it's got
electrolytes what are electrolytes they
even know so what our block chains do we
even know that's what I want to ask
these people who don't seem to
understand what I understand they seem
to have a slightly different perspective
on the view than I do for me block
chains are a tool they're really
wonderful tool but they're not going to
replace all other tools though hopefully
maybe join an arsenal of other solutions
that are out there but really the
properties of the block chain dictate
the use case my opinion is bitcoins are
really good at value transfer etherium
is really good at trusted computation
both can probably do the other thing but
really they have their niche and that's
kind of it makes sense we see software
serves different roles and for different
needs it shouldn't really surprise
anybody so I would say really
blockchains excel at coordination but
it's not just about the blockchain
theorems written about more components
than just this distributed shared ledger
idea we've written about the idea of
swarm and we're not the only company or
organization out there trying to tackle
this there are lots of companies trying
to do a distributed storage bit torn is
obvious kind of predecessor to all of
this we've also talked about whisper for
dynamic comms messaging etc
and this is kind of important because it
goes back to this property's idea block
chains are really good at coordination
they can do storage for very very
expensive costs they can do messaging
for very very slow block times so if we
kind of build in a couple extra
components we can actually have a more
diverse ecosystem of tools and we when
we start looking at it in this way we
can kind of see it as perhaps a network
database something that the neg gupta is
written about a few times done some
speeches on this is basically the
scenario where code is data they're kind
of both first-class citizens in this
environment which i think is a hugely
powerful idea that we don't fully yet
appreciate yeah automatic
synchronization fault tolerance identity
for free and it's all cryptographically
secured and validated to me as an IT
person who might be implementing a
project in an organization these are
really great things makes my life much
easier and I'd like to bring it into my
organization why well cryptography gives
us nice properties data confidentiality
data integrity authentication
non-repudiation but it's kind of
complicated if you've ever tried to
develop it on Bitcoin it's not the
easiest platform if you've ever tried to
extend the idea of value transfer and do
multi sig or arbitrary computation maybe
you can get away with a few things but
really it excels at value transfer and
storage what we really need for block
chains to take off is for it to be as
easy as web development right javascript
almost every developer can program in
java script if we can make block chains
as easy as javascript everybody can use
block chains in addition to that we've
got organisations building other tools
services frameworks toolkits consensus
is building lots of tools and frameworks
we now have athyrium block chain as a
service on edger so you don't even have
to care about setting up you can just
spin up a vm in the
loud start playing with it testing it
figuring out in the ways in which
athyrium or block chains can help you so
the benefits that I would say you want
to take away with this take back to your
organization your IT managers your
executives is that shared code in this
distributed EVM means consistent and
predictable execution and append only
database that's cryptographically
verified it cannot be tampered with even
by system administrators that's huge for
regulators anybody that's in the
business of auditing accounting or going
to love this and finally automatic and
low-cost distribution using peer-to-peer
technology and this is where the other
components like swarm and whisper will
come in if you couple a blockchain as a
coordination mechanism with something
like bit torn as a data distribution
mechanism and then use something like
tell hash for messaging you have a
really diverse set of tools all
interlinked knowing about each other
cooperating with each other and giving
you this kind of mesh distributed type
network that when an office goes down or
you have a mobile client that is only
partially connected having to deal these
kinds of problems goes away you don't
have to set up database replication it's
given to you for free so these are the
reasons that I think etherium really
beneficial for the enterprise
environment and why you should want to
investigate this not because blockchains
just can remove trust or can remove
intermediaries yes they can do those
things but is in a general sense of
coordination mechanism and having these
this code and data coupled together is a
really powerful idea I've talked to a
few of you throughout the week I've been
working on a project in my spare time
it's got this really awful name but
essentially it's a DAP generator if
you've started working on adapt at all
you'll know that you have to write some
JavaScript put some HTML and elements in
front of it to give it a UI
I found that a bit annoying and I tend
to find myself as a general programmer
does you know abstracting making things
more generic so I wrote an interface to
generate interfaces basically you can
just give it the ABI generated from the
contract and it will give you a free
HTML interface which you can just tweak
with some CSS you don't have to tell
anything about the contract just figures
it out it knows what events to watch for
its really really nice so I think as
tools like this or built up we can
really see more proliferation of this I
tried to record this as a movie to save
me the headache of having to do this
live but my tools refuse to like export
and put it in the presentation so I'm
going to try to do it live here locally
just to kind of show you the idea I'm
running this on my local machine so
hopefully I won't have too many network
problems but we'll see so right just
going to start my minor so I've just
loaded a page here it's connected to our
guests instance we're watching for new
incoming blocks and when blocks our mind
we should see a little update here at
the top here we have our contract this
is just a wallet written in solidity we
can compile this it gives us this ABI
here and from this ABI we get this kind
of free interface down here I've made it
looked like this tab kind of interface
but really this is just CSS making it
look like that you can do anything you
want to it this is all for free I didn't
have to write any of this custom it's
really nice i can deploy a contract
let's see if i can do that now ok so
I've deployed the contract I'm going to
wait for it to mine here there we go so
it's been mocked mind and blocked 7226 I
have the address there which I can see
has been set in the to field here making
it convenient for me to interact with it
let me just grab my
address here I want to check and verify
that i'm actually the owner of this so
go down to his owner paste in my address
you can see it's pulling the fields
together from the actual contract fields
hit call turns true nice can check our
daily limit so for multi sig we have no
limit we want to kind of raise that a
little bit so come down here set it send
the transaction wait for a block to be
mined or two there we go we have a
confirmation really nice we can go back
to check the daily limit hit call
returns 100 as we'd expect it's really
neat I can even go into the logs and
check for my confirmation so I see it
was in some block 7 2 3 4 get logs
there's my confirmation information what
transaction where exactly in chain it
occurred the block hi the transaction
index and you know log index the gas
used and this particular fields on this
now I haven't done anything to tell it
about these contract or the functions or
methods it's been all automatically
generated from this ABI and this is
really where this value comes in of
having code as data having it in the
shared location right we have it in this
one spot we are given an interface on
how to interact with it and no matter
who you are where you are you can
interact with it in the same way if you
were to run this here on your machine
you'll get the same exact results I
think as we push forward these kind of
tools more and more we'll see more
adoption of this in the enterprise and
for me that's where the huge adoption
comes beyond the cryptographic space
thank you very much that's all I have
today
time for questions if anybody has any
minute yes where can we get your code
this is on github my github name is T
Goering I have it running also on the
like github pages but due to the
limitations of browsers between HTTPS
and HTTP it doesn't really work so well
but all you have to do is get clone and
open up index.html and it's there I will
warn you it is under heavy development
and not perfect but the codes on github
any other questions
