so I'm Alex on a Sunday and I want to
talk about the big UX problems and I
think UX is it's important to talk about
UX because the UX is as important as
scalability there is no point in having
a blockchain that can handle a billion
transactions if your apps can't reach
half a billion users right so that's why
it's so important to pay attention to
that now before it was an achievement
I was just in start-up or I founded
syrups failed at most of them and we
learn a lot of metrics that we keep our
eyes on when we are in their startup
Ward's things like the k-factor virality
SEO and we don't talk about those here
because it seems that we we sort of work
in a different level right those rules
don't apply to us but that's not true
right we are in the same game and we
need to pay attention to things like
this this the equation that I used to
spend my my days looking at it's
basically it's also called the key
factor and it's like virality measure
basically what you're doing is every
time your user is exposed to your app in
any way there's a chance that they might
actually pay attention there's if they
do there's a chance that they might want
to sign up there's a chance that they
might complete this I design a process
that they might download the app and
that's after a bunch of steps they might
share some content to let's say ten or
turn your friends so here's the basic
thing multiply all those factors if it's
above one then your app is gonna go to
exponential growth it's if it's slightly
below one then your app is dying and
like pay attention to that is the life
or death of your app because if for
every user you're losing more users and
it means that you need to put more money
to attract more users and that's that
doesn't work
how does it work for each internet for
any of your app it looks terrible it
looks something like this where you go
oh a crypto kitty that's interesting and
then the user has to go into a whole
rabbit hole where they need to really
quickly PDF
and at some point they are taking a
selfie with their passport so they can
get a coinbase account so that it can
get validated in three months
that's crazy no normal app would do that
to you and that's why like outside of us
outside of us like the viral factor it's
zero it's not like 0.9 which is bad it's
zero I mean we've had more i SEOs last
years and we have more daily active
users in anywhere and that's sort of the
point the point is that if you want to
pay the point is if you have if you want
to reach or something else than like
Earth the tech enthusiast those who go
to tech conferences we need to reach
normal people I'm not getting the thing
here so but it's going there right and
what do normal people want normal people
they don't like average users the
medical average users they don't care
about each other they don't care about
your token your ICO your your kaya C
they just want a username they just want
to use an email if they're gonna buy
something why can't they use a credit
card they don't understand why they
can't use a credit card and here's
another thing your users sort of he
expects to be able to use multiple
devices in this with the same account
and that's something like he takes for
granted and it's super hard for us to do
how do we solve that problem first
attempt we try it is every time you
download an your app you create a new
account you write down your seed phrase
you have to move each other to it and if
you want to use the same account let's
say like in and then you install it in
your iPad and then you have to do the
same process and pay to make the
transaction so you can use both your
iPad and your it's crazy then we move to
even worse solution which is let's type
your private key everywhere oh it's here
and I mean there are bad solutions their
solutions are so bad that they create a
scam industry so big that Elon Musk goes
on Twitter and complains about it
I'm very happy that we were like sort of
getting out of this phase where we asked
people to type their private key or tie
or the Siege phrase in order to log into
the app but we're going into I'm seeing
like a few other startups are trying to
solve the problem with a wonderful
interface with a username and email you
go to the server it's super slick it's
beautiful
and I'm better a few people like in the
routiers room that you are working on
that solution right now and if you are
please stop because if you succeed
here's the thing if you succeed doing
that we all fail because I'm not
building we are talking about the
centralization for you to build the next
Facebook Connect because that's what I'm
describing is just Facebook Connect for
each even where you keep all the private
data with them and like we cannot accept
that like we we don't want that to be
the future and I think we can do better
and how I think we can do better is this
thing I'm calling universal games it's
not a single service is not a single
website is a an architecture that I hope
a lot of that any app can can introduce
and hear how it looks this is all like
life code running I'm just I'm just
recording it just because it's easier
but the idea is that it's just like a
website where you click and you type
your name that's all I need to do and I
even like show you multiple user names
that you can pick sort of like you can
pick bootable emails and when you do
you're logged in and here's a nice thing
when you are logged in I'm giving you
stuff I create some tokens I'm giving
you tokens the idea being it's
gamification another word we don't use a
lot the idea being that every time you
do something a few actions will cost
tokens other actions will get you tokens
so you're incentivizing the user to do
the right things one of those right
things is when you create a new username
you get a bunch of tokens and here is
the app right the app you can see the
the the tokens called click and I'm just
it's just a single there's a header and
there's a single
button and that button is tied with more
contract when you click that button it
costs you 1 token exactly 1 token if
forget gas free is an etc just cost you
1 token and when you click it you can
see that your name is down there on a
list that people who press the bottom
the app tells nothing right you just
click it and it says you click the
button but the interesting thing is that
you just interacted with a smart
contract the first time on a normal
browser without having to download
anything to sign up anything and for the
smart contract itself it sounds like you
are you are just a normal human account
ok but it sounds weird Alex there's no
password there's no nothing how do I
even like sign up with an iPhone let's
say here's how we do it you just type
your name what's your like you say look
I'm Bob and the nice thing is that once
I can detect that you are Bob I can see
look Bob already exists so instead of
creating a new username I'm gonna
connect you with Bob and when you click
connect to Bob
I will receive a person notification on
my browser and I'm gonna click there and
say yeah that's me that the person that
was trying to connect on an iPhone on
this IP on at that time that's me you
can accept it and when you accept it
what happens is that you're both your
devices will be synchronized and you'll
be able to see soon that the like the on
the top there there's like your your
your yeah and you just get more tokens
because you added a new device and you
can see it's the same address the same
icon because from the point of view of
the of the app you are using the same e
to your account and whatever you do in
one side it will reflect to the other
right so if I click on the phone it will
click on the desktop if I click on a
desktop it clicks on the phone and
here's another thing the the the phone
itself is not a master key I'm not doing
this thing where you do something on the
desktop and then you have to approve in
your master phone device know every
device you every device you add every
new app you
can be an approval or a signer for the
other apps and which already great
because you can have multiple devices
multiple apps everyone using the same
username but what if like if I lose all
my devices well if you lose all your
devices we can do something extra where
I can create a new code for you I'm not
just gonna go very quickly the idea is
just you click it generate some codes on
the on the browser I'm not actually
backing up the keys
I'm just generating new codes on the
browser which you be able to use that's
the code you can print it and then maybe
you cut it cut them out keep them
one-year safe when in your mom's house
the other if your lawyers I don't know
maybe laminate them if you want but the
idea being if you lose all your devices
you can still have access to it via this
the recovery code which is sort of very
easy and how do you sort of save money
when you click the backup code we have
like this three-step security thing
where every time you do something you
like you get more tokens and bling you
just got your your latest thing checked
out so you're super safe how do you do
recovery then just same thing let's say
you lost all your tokens go on the
website type I am Bob and instead of
clicking connect notice that there is a
recovery button on the recover button
you just type one of those codes and I'm
actually typing it instead of just copy
pasting it to see it to show you it's
not something as complex that you need
to actually have a QR code or a digital
file it's something that you can
actually write you might be able to
remember it because it sounds like a
Star Wars planet but it's more it's not
memorable which is writable you can
write that down in a piece of paper
somewhere and when you do you're logged
in notice something that I was able to
log in in multiple devices I have a
paper wallet I am showing a bunch of
stuff here are the things I did not show
you right no mention of eater no head
strings no passwords no cure codes
incremental security it means that the
first time the user logs into the app he
can immediately start playing with it
only after some sometimes some value has
passed I
you should probably download the
smartphone they may be after a few
months maybe after they have a lot of
value maybe encourage them to print and
download the codes and the user just
deployed a mood effect yourself
sovereign smart contractor Canora
identity and they didn't even notice the
thing is we are tricking users into
using bodicek mortising is a complicated
complex thing that only that vans
developers do and instead I'm tricking
them into using it without realizing so
what's the magic we are doing the first
thing is that every app has its own
private key generate the private key as
we already do with apps the difference
here is that don't try to back it up
don't try to take it out of the device
don't keep any money or anything on that
private key instead use that private key
to write to sign a message sterling a
smart contract to do something we call
those messages mera transactions you
probably saw this word you probably seem
like this Mara cartel thing going around
that's it it's about better tamela
transaction is a sign message telling a
smart contract to do something and how
do you do something if you don't have
eater on that device you have a relator
who's every layer anyone with eater an
internet connection can be relator you
can cetera layer for your app you can
have a relator for you can create a
relay or decentralized relay network on
whisper the idea is that you layer
someone who takes that message pays the
gas cost to publish it to the blockchain
and then the contract does something but
way right with someone pay that because
the smart contract because it's smart
can pay back the three layer it can pay
back even depending on how much either
how much gas they spent so what are you
basically saying sign messages saying
look I'm willing to pay let's say one
died or 3 status tokens for someone to
deploy that message for someone and now
any one in the relator network can look
at that and say hey I think I can
probably deploy that for less than that
so I'm taking that I'm getting a 20
and if you need extra recovery keys make
an extra backup for it right don't don't
do a backup of that just do an extra one
the advantage being because it's a more
smart contract you can add conditions
let's say you can only do a recovery key
after the contract has been inactive or
maybe you need to have five four five
trust such friends to be able to do a
recovery you can be creative on whatever
you want to do because it's a smart
contract that's doing the recovery it's
not about just recovering a single key
and we have something very cool also
they're called counterfactual contracts
I hate the name but basically it's a
deterministic contract address I wait
which is idea that you already have the
the contract address before you deploy
it that means that you can already sense
funds to it you can send tokens or eater
to the contract address before you
deploy it it means that you can pretend
for your users that his account is live
until they pay it and then you deploy
the contract and because it works the
mood pool change you can deploy it on a
test net or on a side chain and only
move it to the main chain after the user
has passed some sort of threshold right
I'm still looking for a better name for
that
so another cool thing authorization term
is perky not every key is the same not
every key is as safe as the other
browser keys are not as safe as other
keys so one of the things you can do is
that some keys can can add transactions
other kids cannot add transactions
things like that it's better for users
it's better for apps because you every
time you install a new app you have more
security and and you have
cross-compatible usernames users don't
need eater and that means you can have
more more open business models for
instance you can have a subscription
model where like the user just goes in
and like you pay his transactions for
for for free and then you just ask you
have a credit card system where you just
charge them five five pounds bird per
day so we have less than five minutes I
so yeah we had like a very quick thing
here but I think we are gonna okay
can you do it in two minutes okay
just two minutes wanted to show you how
simple the API we build is so to start
using Universal logins all you need to
do is to create as decay SDK has just
two parameters the address of relayer
and the others of the web pre note then
it just one command to create an
identity you just specify the name of
the name of the identity E&S name of the
identity and you have a private key and
identity a dress as a return and bam you
can send your transaction which looks
pretty much the same as any tomb
transaction with this extra gas talkin
parameters so we can say paying
something else then either and I think
we're running out of time thank you very
much okay now here's the thing I'm not I
don't want here to for us to build the
best onboarding experience in the web I
think we can use the ATM technology to
build the best onboarding experience
anywhere because there's no passwords
and you are in control of your own
identity you're in control of your own
old funds which is something we don't
find in Facebook as a final figure with
layer I would like to thank the kitchen
Community Fund on eff fries they they
have a generous grant that has made this
work possible and of course the TuneIn
Foundation has been supporting all the
crazy stuff I do thank you thank you
[Music]
you
