oh this is the UX prank art room and
it's all about like you know how do we
do blockchain easier and better I think
I wouldn't go quickly to a slice because
it's not that complicated as most people
will get the problem
definitely so we have obviously I would
start with two statements segment one is
I think 2019 is the year of web through
UX I mean that's kind of most people
questions we had so far in the last few
in the last year in the last few months
was can how can we make this work three
easier in better and a lot of actually
solutions already tried onward but it
doesn't really unify in a very common
thing people use and to make it better
the other thing is I guess that's my
assumption is that next year actually we
will see the first applications that
will be used by the mainstream where
adoption might not be even in the port
front and will not be about blockchain
it will be about some cool app or some
cool thing to do and by the way you also
use the blockchain to some degree the
big problems we have with Bronx doctrine
UX or the web 3 UX is maybe actually
start shortly about my background and
everybody knows my background here or
again who does not okay so quickly so I
actually been part of the theme
foundation since 2015 I joined in
January 2015 have built the MIS browser
new people have not heard about that but
in fact in the day it was the first
season first app browser we kind of
coined the term D app and the theme
wallet was one application was in
dismiss browser and I have worked on web
switches kind of like the JavaScript
library
I guess most of you use that is the
library kind of like you know we define
like the first way of how you interact
with so much contracts and one chain and
guess where Fuji is is one of the first
ones that made like building on the
blockchain
easy and more fun to do I hope so my
kind of like bigger work besides like
being in there were three teams it's a
long time actually was the 1.0 build
which was recently developed released so
I have kind of like you know came up
with this API to make it the way how
this and I hope it's intuitive say yes
so the big problem actually so okay okay
it's also easy xx which I propose 2015
that's kind of like what then the non
tech people know and also something
which I will be speaking today which is
is a seven to five some big problems all
unchain is obviously the business
probably the one of the biggest ones you
want to do a cool app which uses
blockchain and the first thing people
encounter is gas and especially even if
you get you even if you come from the
blockchain of Bitcoin community known as
the areum you're totally puzzled what
that even means it's got an extra token
and now if the gas talking actually
people think it's a token so what is gas
and most of the people don't know why I
now need something called ether just to
do something in a box chain based app
and the other big problem is everything
is stored on keys today so the way of
how we interact with the blockchain is
we generate a private key or we have a
private key of some water and this one
signs the transaction and we send it to
the network the problem with this is we
are dealing here with the lowest level
component of how you can interact with a
blockchain and we store all our assets
and our things on that lowest level
a tool or access point by doing that we
run in a few problems you have to back
them up you know you have to actually
ask your user to create a very secure
backup which in today's terms means
writing down words on paper people don't
have so we force them to make
screenshots and storing in iCloud which
is the worst form of safety just in case
you know we have a bit more security the
problem is you know you make people go
through hurdles and complications at the
time where they don't even care you know
or nor know if they ever one day you see
at the first place so you end up with
basically a lot of leg drops out right
at this point of time
so only the tough one really let you
know what's in vests or to something in
is that we'll go through this lengthy
process and you end up with many apps
many backup keys and you somehow have to
manage them you know the old or new say
guess what you know maybe in case we
have some some value in the future on
that and it actually happened a lot of
times I think of crypto kitties you know
whoever thought that this would be worth
anything until it did so used to seven
to five kind of initially was in 2017 or
something the idea okay how can we make
basically in an Unchained account or
back then I call the dungeon identity
until the whole identity community like
backslash don't need Omega RT chemical
edit identity and basically to actually
unify this whole thing of like how I
managed ever my account on chain and how
could I have an account which can
receive actually information and this
led to T years 75 proposal which was in
2017 of Touhou actually and another
thing consider the seven three four
it was rather complex but I think what I
did is for it was for the first time
showing of how can I make a smartphone a
base account with some sort of key
management logic in some
of claims that can attach to this
account and it kind of showed the full
picture of how can this look like in
smart enough language it spurred on it
kind of like activated the whole
discussion around our identity
blockchain and so on even though there
were pretty set I was like you fought on
others who did that before me I kind of
like proposed this out of the feeling of
you know how to urge to do it like I had
also diverse to propose you see 20 in a
more public place rather than this Vikki
page which we had before and you know it
kind of like myself the right timing at
the time and it's dirt this discussion
so all of this came you know people say
alright right there's an eternity stand
up we should all use it and the origin
protocol all guys launch the Alliance
around it and then we had the telecom
channel and a lot of people join this
alliance and kind of everybody like an
huddled around the standard but not
really developed it further or actually
started to use it so one thing is having
a standard the other thing is having an
alliance for a standard but they're
actually important things having people
use it you know and make sense of it
there are also problems especially with
the earlier version of 7 to 5 is that
it's very complex and it is very
specific also and how you do key
management and how you do certain things
and that kind of led a little bit to I
would say a stifled progress or speed of
like adopting it so we had some
discussions with people there we came up
with is a 7 to 5 actually Taylor came
that to me is that hey here have some
ideas and let's talk about it and that
kind of led to the year 7 version 5 by
person
- and the interesting thing about this
it's completely made it simple and I
think you know what if one thing is keys
to success for standard it is simplicity
so easy 20 was kind of the reason why it
was simple to use and is 20 M is 75
version - in my opinion is also key of
why it could be very successful because
it's so simple so in in fact of what
does it does you know it's like okay
this is a smart connect which has an
owner and it's like some some key value
store in there and there's a generic
execute function so it's actually not a
lot of things text part is actually
important because that allows you to do
a lot of things on the blockchain so but
in its core essence what is years in
seven to five and not forget there is
more to standardize on top of that
services not there it's not they all in
one goal the solution but it is a very
key piece because it is the core piece
of a on chain account so basically we
store everything currently on keys if we
replace this by a smart kind of base
account we can add a few properties
which we didn't have before and one is
obviously I can use my account from
different places which is exactly right
now the problem so we all end up having
met amassed may be having some lecture
maybe having some other five apps and
what happens we all use different
accounts and all of them have different
amounts
ether or assets on all of them and some
we don't even know that anymore that we
have and we tend to be not use our own
chain accounts often right you basically
have one account per app which can be
useful it can be very hard to manage
especially when it comes around
dealing with a different type of games
or like one thing to access your your
account in different places so the spot
kinda basic challenge basically allows
you to manage it because it has this
owner address so owner means that is one
address that can control this account
and this one address could obviously be
a simple key it could be a very simple a
private key which would even the first
one you generate in your application so
think of application starts it generates
a key under the hood this key does not
need to be safe because it is a
throwaway key you just use initially and
the moment you get more value to it you
can add more make it more secure so good
you could even think of taking this key
and send it via email as a backup
process so that in case you look loose
yet on the phone in the next few days
you can easily reassociate your previous
account I mean if we think about it we
use email today for we saw as setting
our password all the time right that's
our security measure we have so email
it's silly if you have access to emails
you have access to everybody's accounts
the email is the username and the way to
reset the password that's already a
funny thing so that's the security
measure we have so why not sending a
private key or some kind of generated
link or so directly to this email the
moment you can actually value on your
account or you use it more often for
something then you can actually attach a
movie sick and have that multi-sig being
the control of the account and that
myristic could Ignasi safe it could be a
complex permission contract that allows
certain parties to do certain things
through this seven to five account and
others not so think of like you are a
company and the seven to five is your
company's official address if you have a
commissioned contract where the intern
can actually talk through the official
address but only can talk to certain
accounts or certain smart contracts and
call only certain functions you can have
your intern
we use the official account without any
kind of a security loss or it could be
just a simple would be sick or on top of
this this disallows also social recovery
schemes and whatever else because
whatever we come up with better ways of
managing keys we can attach to the same
existing account or to multiple of doors
the important thing also is we can have
meta transactions we can use the gas
station network or other related
services within those key managed
accounts and suddenly completely hide
the fact that a server a fee to be paid
the future of blockchain should be the
way of how the web works today
meaning the application developers or
the company who does it should build the
I should pay for the usage at least to
some degree until there's a way to
recoup the payment I mean today nobody
is paying for service of applications
that we just download and use them all
the time it should be the same with web
3 the relay protection service is
actually the key piece to make it easy
but this allows a lot more things so
this in the first instance creates a
management account
so now I all not only have one key but I
have a key or an account that I have can
manage in all kind of ways and you know
we can amend a lot of new things on how
we manage doors but I can also attach
information to it and that's what this
key value stores for so the key value
stores by 32 and bytes s value this
means it can come up with all kind of
things that we allow to be attached to
such an account and this can be
completely random things of links to
reputation systems or whatever maybe
from something you could simply attach
an hour talk to this account to make it
somewhat cooler right
or the company's local or whatever but
you can also link to all kind of other
obtain more identifiable data that you
don't want to reveal on chain but that
somehow should be referenced and linked
to the public identity or the public
account you have here and whatever you
come up with you know batches reputation
systems link tokens whatever I mean you
cannot just on these efforts have a lot
of NFC sitting or batches whatever but
you can also link to an extra reputation
system sitting in another smart contract
that allows a lot of flexibility and
because there's so many more things we
don't know what is coming having a key
value store really allows for all kind
of new things you know we don't need to
think about everything right now and
having to find these five things you can
do on an unguent account it's an
open-ended system so that actually
creates a manageable verified account so
using this as the default and beauty
here is you can start out with a key
verification the moment somebody
purchased something or doesn't actually
somehow creates value or money spend you
can on the fly just create an account
for him where this key is the owner the
beauty is that now this person could
actually take this account and take it
into another application so we all start
to use the same default account standard
you can take your account across all of
these different applications and it's a
lot more manageable and it's a lot more
easy to interact with one chain things
so that can be rather cheap to deploy I
mean these are transactions 21,000 gasps
32,000 for deploying a library that can
be as cheap as you can get and it's
basically it could be a long lasting
manageable account and because it's a
small contract and smartphones can talk
to other smart contracts that's the big
big magic thing which I guess a lot of
people also that the film space has not
have
fully understood why he was awesome and
the evm in fact is because of that fact
that you can talk to other smart
contracts that kind of makes your own
shell account the actor on chain this
means for other systems outside it's the
same like before you know if a key is
talking to you or smartphone app you
don't care in fact here you can even
check this month conduct we read some
information you need maybe some
verification or maybe some attach claims
you somehow need and do something with
them so message sender you know that's
what all it doesn't necessarily need to
be your person this could be one account
you use you can have fifty if you want
to I guess we end up with just a few and
but you can use them for different
personas you don't necessarily need to
upload your picture and then go to the
government and put the poo when you want
an account just to prove that this is
your account and then go everybody show
everybody what you do but one of the
biggest pieces in our society is
actually transparency we are on Twitter
and on Facebook on all of these
platforms because we want to express
ourselves so that expression needs a
identity you can actually or an account
an extra take around where would you
correct right you can take care of that
whatever is on there is what we want to
put out there and seventy-five can be
done also for companies also for
organizations technically speaking the
if your foundation should have a 75
account and not the etherium multi-sig
from three years ago in official address
which we all look at right so it's your
Unchained account and it should be your
gateway to decentralized world and if
you want to do an energy then you rather
look into off chain solutions like
verifiable claims Doubletree see does
great work on that and it's a lot of
projects like three quarks and item
three and you port and your Lacan which
are working on
it's kind of like real-world identities
work which are not necessarily on the
blockchain or only a flex light Jesus on
the blockchain so what we have done is
this the Eastern 75 Alliance obviously
that's this the official of security
implementation up to 75 version two as
well they'll always it the issue where
we discussed because currently the main
thing we are doing analyzer this morning
screen so the standard scenario so I'm
working on this project lock so so this
is a blockchain for the a new credit
economies how we call it all for the
lifestyle space one important thing here
is this is the grameen of people who
does not know tank nor one to understand
book chain but they might want to create
tokens or own things physically in
digital so you need to make it easy for
them to interact with the blockchain so
we are developing and iterating on
standard scenarios means like different
standards like seven to five likely to
certificates and others
we're kind of like trying things out you
know how it is could work in the whole
flow together how it can own token
there's a new standard we proposed which
is the lowest one is actually a
universal receiver standard that
probably is the whole discussion itself
but we have very short we have this
problem of many tokens implementing
different type of receiver functions so
seven seven has token received year C
two to three has I think also something
with token fallback function or whatever
I call so everybody has different
function names if I want to have a
generic account like it in 75 I run into
the problem that that I have to
implement at least like five different
functions to receive different type of
tokens or entities if we use a universal
receiver is the one common function name
the type and some data you passed with
it you can be you are able to receive
everything even future assets because
you could operate either this part that
receive stuff or just let your interface
deal with whatever you received so the
universal receiver is a very incremental
piece in an on chain account for example
and that's something we've proposed in
our standards repository because it
looks our standards process LSP so
that's very much like the EIP repository
just that is so the only difference is
that it's a it's the blockchain around
this lifestyle arena so we can discuss
in a more calm space and it's not
already so totally busy with a lot of
competing standards we are in these
standards warm you know everybody has
the better centers and we don't talk
anymore about more complex interaction
models and the thing you have got a
standard scenario and also or the LS
piece we promote promote here is that we
think not only about the individual
standards but how this works in concert
you know how can I make sure that I can
easily read a portfolio of a given
address how tokens interactive identity
is how identities can receive somewhat
different tokens into the future ones so
there's a lot of things we should think
more about how stuff works together and
not just everybody comes up with that
standard now we have one little more
building block but five of ten you know
and then they all don't work together
and accounts reading talk with each
other super complicated
totally hacky so we wanna have
compatibility means we need standards
that kind of fit together that's already
a question here
hi we can say real words applications
and posted as account about what about
doing library
but it's way like vacation
so basically libraries force month
contact I mean open setting is kind of
like the biggest library for
standardized smartphone works we have
and I'm really understanding question
it's something like an open source I
mean something is kind of open source
but you're talking about like how can
other people contribute with different
pieces or how do you have
like perturbation in
okay so if you want to kind of like
attention formation like this it
obviously belongs into the set data the
key value store if you want to have
email verification you always have to
think about what this is you launch an
account so you have continued teach you
you know so of what they shoe that
shouldn't do what I mean for couple
through interfaces we know that when we
post something Instagram it's pretty
public so people are not posting their
private naked pictures so here we have
to treat it the same you're posting it
unchanged so it could potentially be
read by people so also making sure that
what you would like that this is a
public persona Ukrainian here versus
maybe a private persona if you want to
verify your manifest and I guess this
service book should verify that
and you could simply attach a signed
message into one of the key value store
which says okay we check the email and
SMS play yeah that's what we would do I
mean either this or a some kind of like
registry which does like a verification
someone you service could end the next
rest month come back with just
verification and then in the key value
store you simply link to that registry
that could be another way so the beauty
of this key value stores it can contain
data on its own but it could be also
simply referencing other places to go
look and if we standardize these
processes we exactly know what to do now
- each Kiba store that's yes
instead of just happy no statement the
proxy and control still unchanged
because you can upgrade your new key
management I mean you can build it then
it's all in one contract from some of
the own address could be itself you
could make enough I mean actually
happily on for me who sooner wallet
build exactly a seven to five
upgradeable contract where you basically
have one address which contains the key
values to an an owner and an additional
like management keys systems you can
build it as well and on the end you
wallet only needs all your interface
only needs to know gets the address it's
the owner is the same Metro so what's
the different address and then it has to
look at what standard this is you know
what kind of commercial thing it is so
you can deal with that as well and then
you can interact in this account in the
simplest form is just a key you know
which you have in your code but yeah
could be in the same account I think
keeping it separate makes a lot of sense
because what I see is happening is you
have and I know what the time is up and
I'm just to keep the short this is
permanent account 175 is probably
something we want to keep for a while
and use it in maybe some games or
whatever else so it's a permanent thing
we want to be secured the key manager is
maybe something we can upgrade over time
so having this in a separate smart
contract keeps the risk lower for
example the universe receiver contract
the contract which knows how to deal
with stuff you receive should also be a
separate module because I assumed people
will have paid that very frequently and
if you all pack into one account then
suddenly all of this code can buy it
into the same slots potentially
overriding all of the importance
in there so keeping this in separate
addresses which cannot really do things
on the other side makes it more safe I
mean is I assume there will be a future
where people go to website and say hey
download this new universe would receive
our contract because now it's portable
at the bar and then you just go ahead
and upgrade your your account with this
and if this would be the same account
maybe just move your assets around or
variety of storage values like this is
the worst thing you can do is notify
your interface box with the wrong Locker
so practice good I think that's it
time's up thank you so much
[Applause]
