It
works
as
a
smart
contract
on
top
of
your
blockchain
and
it
combines
the
best
of
two
worlds
from
ethereum
we
are
taking
the
runtime
and
all
of
the
tooling
that
is
developed
from
the
near
ecosystem.
We
are
taking
scalability
performance,
how
low
transaction
fees
and
so
on,
and
we're
combining
these
two
things
into
one
which
is
called
aurora.
B
We
do
have
a
familiar
things
available
to
everybody
in
the
aurora
ecosystem.
We
have
a
web
3
compatible
rpc,
so
all
of
the
ethereum
tools
can
connect
to
it
directly,
including
meta,
masks
and
other
different
wallets
coin
based
wallet.
If
somebody
uses
it
different
wallet,
connect,
wallets
and
then
also
remix,
truffle,
hard
hat
everything
that
is
there
in
the
ethereum
ecosystem.
Since
web
3
json
rpc,
is
a
standard.
B
Now
all
of
these
things
are
capable
to
be
connected
to
aurora
our
base,
token
of
or
the
base
token
of
aurora
or
the
token
in
which
users
are
paying
fees
or
sometimes
paying
fees.
We
are
going
to
touch
base
on
this
a
little
bit
later.
Is
it
we
are
not
compromising
the
full
compatibility
with
ethereum
blockchain.
B
B
B
Over
time
you
have
free
transactions
this
month
you
have
for
transactions
next
month
and
so
on
and
last
but
not
least
on
this
slide
is
that
we
are
our
builders
and
maintainers
of
the
rainbow
bridge,
the
bridge
in
between
ethereum
near
and
aurora
systems.
All
of
these
things.
This
is
something
that
we
are
doing,
and
this
is
you
know,
a
very,
very
quick
overview
of
aurora,
but
many
of
these
things
have
been
developed
over
the
past
year,
so
we
are
going
to
go
a
little
bit
inside
of
it
now.
B
If
there
is
one
thought
that
I
would
want
you
to
live
from
after
this
talk
and
after
everything
that
you're
going
to
hear
here,
this
is
it.
I
do
believe
that
aurora
is
the
best
l2
solution
in
the
market,
and
this
is
not
just
kind
of
one
thought.
I'm
going
to
prove
it
to
you
over
the
course
of
the
next
slides.
B
B
B
B
B
You
must
protect
your
users
and,
moreover,
many
many
systems
in
rainbow
bridge
are
working
automatically
to
resist
attacks,
and
one
of
these
attacks
was
happening
just
three
months
ago
or
to
like
on
the
first
of
may,
somebody
was
trying
to
to
attack
our
bridge
and
then
our
system
just
prevented
the
heck
of
one
1.5
billion
automatically,
without
even
us
understanding
what
was
happening
so
we
needed
to
recruit.
We
need
we
needed
to
figure
out
what
was
happening
there,
a
little
bit
after
it.
B
We
do
believe
that
this
is
something
that
is
absolutely
needed
to
get
to
the
point
when,
when
we
can
say
that
there
is
a
mass
adoption
for
the
users
web
2
people
are
not
understanding
web
3
and,
in
case
we're
not
going
to
change
the
user
experience
of
stuck
transactions,
constant
the
need
of
constantly
checking
what
is
the
gas
price?
You
know,
resending
the
transactions
checking
the
nunces
and
all
of
the
stuff
in
case
we
are
not
going
to
change
it.
B
We
are
not
going
to
get
to
the
mass
adoption,
so
aurora
plus
implements
familiar
things
for
web
2
users.
It.
It
has
a
premium
model
you
register
with
aurora,
plus
in
one
minute,
you
are
having
50
free
transactions
on
aurora
per
month
and
every
month
these
free
transactions
are
there
for
you,
you
can,
you
can
use
them,
and
on
top
of
this
we
would
like
to
add
and
that's
why
it
is
in
kind
of
the
red
color.
We.
B
B
So,
according
to
our
data,
since
we
are
working
with
lots
of
rpc
providers,
including
pocket
network
and
fiora
alchemy,
our
rpc
infrastructure
developed
internally
to
su
and
which
is
available
to
all
of
the
aurora
ecosystem,
is
at
least
20
times
more
efficient
than
any
other
rpc
out
there
in
the
market,
and
I'm
talking
about
right
now
specialized
rpc
companies
that
are
building
their
businesses
around
it.
I'm
not
talking
about
kind
of
l
ones
that
are
building
some
kind
of
rpc
infrastructure.
B
This
is
a
great
tool,
it
is
unseen,
but
this
is
something
that
is
going
to
support
that
user
growth,
and
you
will
see
more
and
more
advances
around
rpc
in
the
following
months
and
in
case
you
have
not
seen
it,
and
I
believe
this
is
one
of
the
biggest
achievements
for
aurora
plus.
We
have
done
a
an
absolutely
great
product
rollout,
so
we
are
also
moving
not
only
in
the
technical
direction,
but
we
are
kind
of
doing
our
first
steps
in
the
marketing
and
our
own
team
cook
was
presenting
it.
B
B
And
yeah
this
has
happened
because
of
of
my
colleagues.
This
is
all
all
of
these
products
that
I'm
talking
about.
They
are.
They
have
been
built
internally
inside
of
our
labs,
and
one
year
ago
we
were
just
13
people
that
have
spun
out
from
near
and
organized
our
own
company,
and
we
were
just
pretty
afraid
of
all
of
the
things
that
are
happening,
but
we
continued
to
build,
and
now
we
are
65..
B
Thanks,
but
this
is
not
even
close
to
all
of
the
achievements
of
the
aurora
ecosystem,
and
I'm
just
going
to
show
you
one
simple
slide
that
that
that
you
can
understand
that
it
is
like
everything
that
we
do
is
just
kind
of
our
own
small
contribution
to
what
the
community
is
doing
here.
It
is,
this
is
the
tree
of
all
of
the
different
projects
that
are
already
working
on
aurora
or
are
going
to
launch
each
apple
on
the
tree
is
already
launched
project
some
kind
of
apples
that
are
kind
of
green.
B
They
are
still
in
the
development
and
they
are
going
to
be
launched
soon,
so
aurora
plus
rainbow
bridge.
Well,
these
are
just
two
apples,
and
all
of
the
rest
is.
This
is
something
that
was
built
by
you
by
the
aurora
community
and,
from
my
point
of
view,
this
is
just
just
amazing.
We
actually
have
more
than
150
applications
live
on
aurora
today,
within
one
year
time
frame.
B
So
I'm
going
to
just
to
list
some
of
the
community
achievements
defy
ecosystem
on
aurora
was
booming
before
before
the
market
crash,
and
I
do
believe
that
is
going
to
continue
its
growth.
It
was
topping
up
more
than
2.5
billion
in
tvl
it
was
entering
top
10
according
to
d5
llama
of
the
different
of
the
ecosystems.
B
We
are
all
of
the
applications
in
aurora
right
now
having
more
than
2.5
million
transactions
a
week,
which
is
something
like
one
third
of
the
lot
of
ethereum.
So
approximately
a
third
of
all
of
the
transactions
on
the
theorem
right
now
are
happening.
One
aurora,
literally
etherscan
infuria,
metamosque
institutional,
the
graph
covalent
curve,
gnosis
xeron
and
many
many
other
blue
chip
projects
from
the
ethereum
ecosystem.
B
They
feel
on
aurora
like
home,
and
they
already
integrated
and
the
amount
of
this
project
continues
to
grow,
so
expect
additional
announcements
about
about
the
blue
chips
launching
on
aurora
one
of
our
projects,
our
both
of
our
biggest
london
solution,
bastion
and
origami,
are
having
zero
bad
debt,
and
there
are
not
that
much
of
london
protocols
that
are
that
are
out
there
across
all
of
the
blockchains
montflower
farmers.
The
game
that
is
a
that
is
a
fork
of
a
sunflower
farmers.
Famous
sunflower
farmers
that
break
polygon.
B
They
launched
on
aurora
at
the
moment
when
all
of
the
transactions
on
aurora
were
free,
so
people
were
able
to
transact
for
free
on
aurora
and
play
that
game
that
poorly
designed
game
that
creates
insane
loads
on
the
network.
Now
this
game
didn't
break
aurora,
which
means
that
the
combination
of
aurora,
the
rpc
and
also
the
near
protocol
as
a
basement
is
super.
Super
robust
refinance,
which
is
a
near
native
amm
solution,
is
now
doing
the
swaps
on
aurora
through
trisolaris,
which
is
aurora's
biggest
amm
at
the
moment.
B
Aurora
boats
by
lawmaking
they're
one
of
the
most
traded
and
most
desired
nft
collection
out
there,
and
there
are
lots
of
lots
of
activities
around
fundraising
in
the
raw
ecosystem,
and
even
here,
I've
already
seen
some
of
the
vcs
that
are
capable
to
help
you
in
case.
You
are
building
projects
and
we
also
obviously
are
willing
to
help
our
ecosystem
to
connect
with
vcs,
and
there
are
multiple
teams
that
are
at
the
moment
at
the
stage
of
raising
their
rounds.
B
And
the
last
thing
with
which
I
would
like
to
end
is
that
just
recently,
aurora
launched
its
community
grants
program
and
everyone
who
is
willing
to
grow
the
community.
Everyone
who
has
the
ideas
about
creating
the
content,
doing
hackathons
doing
this
kind
of
podcasts
you're.
All
welcome
just
to
follow
these
three
simple
steps
and
be
able
to
get
funding
for
your
ideas,
so
encourage
everybody
who
is
willing
to
do
this.
B
B
Our
systems
are
nominal,
we're
not
hacked.
We
are
we're
continuing
our
development
and
stay
tuned
and
please
do
not
do
not
be
super
upset
about
the
current
crypto
situation.
We
are
going
to
survive.
We
are
going
to
move
through
these
times
and
everything
will
be
just
great
thanks.
Everybody
for
participating
in
the
aurora
community.
A
Thank
you.
Thank
you,
so
much
alex
for
your
amazing
presentation
and
we
have
time
for
some
questions.
So
probably,
if
you
have
questions
just
raise
your
hand
and
I
come
with
micro,
no
questions
so
far.
Okay,
that's
great!
I
think
next
speakers
will
continue
your
story.
Thank
you
so
much
alex
and
I
am
glad
to
present
you
our
next
speaker
max
simpson,
cavic
co-founder
of
atomic
green,
with
a
talk,
the
future
of
the
centralized
finance.
C
D
A
F
F
F
What
are
the
first
words
that
are
coming
to
the
people's
minds
when
they
hear
the
word
defy
apart
from
decentralized
24,
7,
accessible,
not
controlled
by
anybody,
couldn't
be
blocked.
I
think
the
three
words
that
describe
defy
now
could
be
taxes,
landing
and
farming.
This
is
how
people
the
majority
of
people,
probably
they
understand
the
defy
now.
F
In
our
point
of
view,
this
represents
defy
in
a
very
embryonic
state,
but
it's
just
a
baby
just
born,
but
it
has
a
lot
of
room
to
grow
and
a
lot
of
time
to
pass
until
it
develops,
but
not
to
be
unfounded
about
this.
I
wanted
to
look
through
several
charts,
comparing
the
traditional
financials
markets
to
the
crypto
markets
and
then
we'll
be
able
to
move
to
the
future
of
the
defy
based
on
this.
F
If
you
look
on
this
chart
in
the
traditional
financial
system
derivatives,
they
represent
the
majority
part
of
all
the
volumes
with
more
than
600
trillion
dollars
in
the
total
value
of
the
derivatives.
Only
and
you
see
that
crypto
is
just
at
the
end
and
derivatives
could
be
the
top
or
just
the
basis
of
all
the
traditional
financial
systems.
F
If
we
are
diving
deeper
to
the
market
sales
ratios,
you
can
see
that
this
is
like
the
real
size.
Sometimes,
the
the
world
derivative
market
is
very
big,
and
this
is
the
major
system,
the
major
financial
system,
where
the
derivatives
they
form
the
basis
of
all
the
markets
and
the
d5
it's
somewhere
there
at
the
end,
with
a
total
d5
value
of
89
billion,
probably
now
it's
a
bit
bigger
and
the
derivative
of
markets
and
defy
it's
only
1.3
1.5
billion
dollars
very
small,
very
tiny,
and
at
this
point
we
talked
to
us
whoa.
F
There
is
a
big
room
to
grow.
Comparing
to
the
traditional
financial
systems
so
diving
deeper
to
the
derivatives
and
the
crypto,
we
wanted
to
share
the
overall
volumes
of
the
derivative
trading
on
centralized
exchanges.
Crypto
exchanges,
which
is
290
billion
daily
and
the
spot
market
trading
on
texas
is
only
120
billion.
So,
as
you
can
see
in
the
centralized
crypto
market,
this
ratio
is
not
so
bad.
F
Comparing
to
the
traditional
financial
market
is
bigger
the
derivatives,
but
if
we
go
to
the
decentralized
exchanges,
it's
vice
versa
and
the
derivatives
trading
on
the
taxes
are
only
1.31.5
billion
daily,
while
the
spot
trading
is
almost
twice
bigger.
This
is
the
second
time
we
told
to
us
whoa.
There
is
a
room
to
grow
in
the
decentralized
derivatives,
but
before
we
start
about
the
future,
what
were
missing
in
defy
comparing
to
the
traditional
financial
systems
that
sometimes
they
are
represented
already,
but
they're,
very
tiny
and
very
rudimentary
and
have
to
be
developed.
F
These
are
insurances,
interest,
swaps,
it's
very
difficult
theme
in
the
financial
world,
traditional
system,
but
it
could
be
translated
to
the
crypt
as
well
and
to
the
derivatives
then
bonds.
Everyone
know
what
is
bonds
and
somehow
there
exists
some
types
of
bonds
now
in
crypto
and
forwards.
This
is
more
technical
thing
about
the
options
forward,
but
all
of
these
form
part
of
derivatives.
F
F
This
is
the
thing
that
actually
there
it
is
afford
its
agent
and
speculations,
but
for
now
in
defy,
we
see
only
speculations,
but
there
is
almost
no
hedging
people,
don't
use
it
for
hedging,
but
forever.
Speaking
about
the
crypto
derivatives,
there
are
a
few
very
inherent
advantages
of
them
comparing
to
the
traditional
financial
markets,
and
we
think
that
this
will
float
some
derivatives
to
the
crypto
derivatives
from
the
traditional
markets.
F
They
are
easily
accessible.
It
means
that
literally
everybody
in
the
world
that
have
a
device
that
have
a
connection
to
the
internet
and
the
web
3
wallet
installed
in
it.
They
can
access
crypto
derivative
and
the
device
as
it
is,
and
the
second
one
is
that
they're
easily
created
in
traditional
finance
to
create
a
derivative
and
to
list
it.
You
need
a
lot
of
money,
sometimes
millions
of
dollars,
a
lot
of
people
to
create
and
list
it
and
a
lot
of
time.
Vice
versa.
F
Another
big
block
for
the
d5
in
the
future
is
the
debt
market.
Actually,
we
have
some
players
and
they
define
the
debt
market
like
our
compound
or
make
it
dao
there.
You
put
the
collateral
and
you
can
take
a
loan
and,
of
course,
there
are
some
projects
that
take
like
collateral
nfts
now,
but
they're
also
at
the
very
beginning,
but
we
truly
believe
that
in
future
projects
and
dows
should
have
the
possibility
to
emit
their
own
bones.
F
F
Also
another
thing
is
the
leverage
market,
it's
not
actually
the
derivative,
but
it's
a
big
block
because
it
uses
not
the
synthetic
other
books
but
the
liquid
other
books.
There
are
a
lot
of
projects
now
in
the
d5,
not
a
lot
a
few
of
them
with
the
leverage
trading
that
tend
to
be
decentralized
but
actually
they're
mimicking
to
be
decentralized
and
they're.
Centralized,
because
once
you
need
to
deposit
assets
to
any
account
within
the
ecosystem,
it's
already
not
decentralization.
F
Another
thing
is
using
the
liquid
book
or
the
book,
for
example
like
universe,
3
or
the
project
that
will
be
launching
an
aurora
that
is
called
izumi
and
the
project
that
represents
this
type
of
product
is
atomic
green
I'll
speak
a
bit
about
it.
Later
we
have
in
atomic
green
the
landing
protocol,
the
leverage
and
the
imm
that
will
be
built
in
the
future
versions,
but
it's
like
a
long-term
long-term
things,
how
it
works.
F
F
The
second
part
is
much
more
complete
and
this
is
where
the
magic
happens.
So
this
is
the
controller,
for
example,
when
the
user
wants
to
open
the
position
short
or
long
controller
borrows
the
front
from
the
landing
pool
after
that,
depending
on
the
situation,
whether
he
goes
short
or
long,
it
sells
for
by
the
underlying
assets
and
positions,
the
liquidity
to
the
univ3
pool
or
the
izumi
pool
in
the
range
a
bit
higher
than
the
take
profit
or
stop
loss
of
the
user.
F
F
The
controller
says
the
underlying
assets
repays
the
landing
pool,
and
then
it
distributes
the
p
l
and
the
fee
among
the
lender,
the
trader
and
the
platform
as
it
is
when
its
liquidation
is
a
bit
different.
It
sells
the
collateral
of
the
person
and
it
repays
the
lending
and
distribute
defeats
as
well,
making
it
everything
to
summon
it
up.
F
A
A
A
G
So
good
afternoon,
everyone
it's
a
quick
introduction
of
myself,
I'm
ey
founder
of
origami
whoa.
Okay,
that's
a
that's
a
very
good
introduction.
Okay,
so
thank
you
for
joining
me
here
today,
we'll
be
sharing
more
about
origami's,
exciting
journey
on
aurora
so
far,
and
also
sharing
some
of
the
insights
that
we
have
learned
throughout.
G
G
G
We
are.
We
benefited
tremendously
from
the
support
given
to
us
by
proximity,
labs
and
our
team,
so
our
next
monsoon
was
in
february
where
we
were
quite
fortunate
to
write
on
the
excitement
generated
by
the
ecosystem
and
we
managed
to
raise
a
9.5
million
round
which
was
co-led
by
dragonfly
capital
and
pollution
capital
straight
after
that
we
were
successful
to
be
able
to
be
the
first
money
market
launched
on
aurora.
G
The
first
milestone
I'd
like
to
talk
a
bit
about
a
bit
more.
Is
our
product
launch
in
march
right.
So
the
very
first
challenge
that
we
faced
was:
how
can
we
be
quick
and
fast
enough
to
seize
the
first
move
advantage
and
be
the
first
money
market
on
aurora,
and
through
this
we
had
this
amazing
opportunity
to
work
very
closely
with
the
aurora
dev
team
to
optimize
the
aurora
engine,
culminating
in
the
release
of
engine
2.4.0,
where
we
doubled
the
gas
efficiency.
G
So
a
short
recap
for
everyone
here
on
the
basics
of
the
transactions
right.
So,
as
we
all
know,
aurora
engine
is
a
smart
contract
layer
on
top
of
near
blockchain.
It
also
has
a
full
evm
integrator,
allowing
us
to
execute
ethereum
transactions,
so
when
assigned
ethereum
transaction
is
sent
to
an
rpc,
what
happens
it's
wrapped
into
a
near
blockchain,
so
by
logic,
all
transactions
on
aurora
must
follow
the
same
logic
on
your
blockchain.
G
G
So
what
our
team
has
done
is
to
really
understand
how
the
trance
compiler,
which
is
the
spanning
vm
works,
and
how
the
evm
gas
correlates
with
the
near
gas.
So
we
deployed
hundreds
of
contracts
we
meticulously
profile
and
study
them,
and
what
we
found
is
that
there
are
certain
irregularities
in
the
cost
of
reading
variable
from
storage.
G
G
So
over
here
I
think
just
to
share
for
us.
I
think
we
can
for
the
builders
out
there
consider
deploying
your
native
tokens
on
ethereum
and
then
bridge
them
over
to
near
and
aurora.
For
us,
we
found
that
that's
the
most
effective
way
of
making
sure
that
your
native
token
is
available
across
chain.
So
it's
something
to
consider.
G
Next,
I'd
like
to
share
something:
that's
unique
to
origami,
which
is
the
paper
mill.
So,
as
all
of
you
know,
liquidity
mining
is
a
critical
part
of
bootstrapping
for
all
d5
projects,
but
more
often
than
not
people
or
the
early
liquidity
miners
will
leave
and
redeploy
their
capital
elsewhere
when
there's
newer
projects
coming
up.
So
this
is
our
attempt
to
solve
this
issue.
G
G
G
Firstly,
it
allows
users
or
investors
that
wants
to
long
play
an
opportunity
to
buy
pulp
at
a
discount
in
the
market
right
and
secondly,
by
introducing
gamification
into
into
the
paper
mill.
We
are
able
to
incentivize
our
liquidity
minus
to
delay
claiming
of
their
rewards,
thereby
prolonging
the
release
of
ply
into
the
circulating
supply
and
reducing
the
cell
pressure.
G
G
Only
32
has
been
claimed
and
only
four
percent
of
ply
has
been
added
to
the
circulating
supply,
but
actually,
more
importantly,
what
we
are
proud
to
see
is
the
concept
of
liquid
log
tokens
being
adopted
for
other
use
cases.
One
example
is
the
aurora
futures,
which
was
announced.
I
think
two
weeks
ago,
where
the
aurora
team
distributed
long
aurora
tokens
to
their
team
members
so
yeah.
G
So
when
it
comes
to
designing
tokenomics
it
really
it's
crucial
for
us
to
try
to
find
something
that
fits
to
your
main
product
offerings
and
not
just
jump
on
the
latest
bandwagon
or
trends
such
as
the
va
token,
so
origami.
Of
course,
we're
committed
to
support
all
protocols
to
come
onto
aurora
we're
very
excited
to
grow
the
ecosystem.
Together,
we
recently
launched
our
ecosystem
liquidity
pool,
which
can
help
to
incentivize
and
attract
more
liquidity
onto
to
our
partners.
G
As
an
early
builder
aurora,
our
dev
team
has
went
through
a
lot
of
contract
intervention
interactions
and
they
know
very
well
how
to
optimize
certain
contracts
so
do
reach
out
to
us.
If
you
feel
that
you
need
help
in
that,
we
also
offer
customized
borrowing
arrangements
for
projects
and
also
for
treasury
diversification
purpose
and
lastly,
of
course,
we're
always
on
the
lookout
to
list
new
tokens
and
new
assets
on
our
platform.
G
A
A
A
A
I
just
wanted
to
remind
you
that
we
have
some
activities
coffee
upstairs.
We
have
live
translation
and
also
we
have
live
broadcast
on
in
youtube.
So
we
have
a
link
on
event
tribe.
We
have
this
link
in
our
twitter,
so
you
can
share
it
as
well
and
another
fun
activity.
You
can
get
100
euro
deposits
to
near
swag
shop.
A
A
By
the
way
tomorrow,
we
will
be
open
as
well.
There
is
a
lot
of
great
activities.
Speakers
office
hours
as
well,
we'll
open
our
doors
from
nine
o'clock.
We'll
have
some
coffee
breakfast
so
join
us
okay,
great-
and
I
just
wanted
to
remind
you
that
we're
right
on
the
middle
of
our
beaches.
Today
we
have
three
more
speakers
and
after
that
we
will
move
on
to
our
best
and
favorite
part,
it's
happy
hours,
so
we
will
have
some
cocktails
networking.
We
have
some
drinks.
We
have
a
lot
of
great
people
here
today.
A
H
H
H
Of
course,
interoperability
is
not
a
new
concept.
There's
many
existing
providers.
That's
really
tried
to
tackle
this
problem,
but,
as
you
guys
hear
it
time
and
time
again,
bridges
are
dangerous
and
carries
massive
security
risks.
But
the
question
is
why:
why
are
these
interoperability
solutions
and
bridges
so
dangerous?
We
did
very
detailed
analysis
of
every
single
bridgehack
and
exploit,
and
our
key
takeaway
is
that
they
all
had
very
centralized
architecture
and
most
often
times
offered
pairwise
connections,
not
to
mention
they
also
had
very
complex
user
experiences.
H
So
how
is
axler
different
axler
is
the
most
secure
cross-chain
communication
platform,
because
we're
the
only
one
that's
decentralized
and
permissionless.
What
does
that
really
mean?
Our
our
architecture
is
modeled
off
of
proof-of-stake
blockchain
built
on
cosmos
sdk,
and
we
have
our
own
diverse,
set
of
validators
that
secure
the
network.
Why
do
we
build
it?
This
way
proof
of
stake.
Blockchain
has
been
around
for
a
long
time
and
it's
been
battle
tested.
We
believe
this
security
model
is
the
best
chance
at
staying
safe
from
exploits
some
of
the
other
cool
things
about
axler.
H
Is
we
built
our
out
our
own
set
of
apis
and
sdks?
That
makes
the
integration
process
as
simple
as
possible?
You'll
also
obtain
network
effects
when
you
work
with
axler,
because
we
offer
many-to-many
connectivity
once
we
integrate
a
new
blockchain
or
asset
onto
a
network.
Anyone
that's
already
plugged
in
our
apis
will
automatically
be
interoperable
with
with
these
new
networks
so
as
axler
scale,
you'll
scale
with
us,
therefore,
future
proofing,
your
business
and
your
protocol.
H
Lastly,
what
we're
really
excited
about
is
one
click
experiences
with
general
message.
Passing
you're
now
able
to
do
multi-step
contract
calls
across
any
of
the
chains
connected
on
the
axler
network.
Practically
as
a
developer.
You
can
now
build
one-click
applications
with
very
complicated
smart
contract
logic
on
the
back
end,
so
that
very
new
users
can
use
your
application
easily
driving
adoption
for
aurora
and
for
web3.
H
H
So
because
we
don't
have
internet,
I'm
not
going
to
be
able
to
show
you
guys
axler
scan,
but
I'll,
send
the
links
out
afterwards.
Axle
scan
is
our
block
explorer
that
was
actually
built
by
our
community.
Given
that
we're
fully
decentralized
on
axle
scan,
you
can
see
everything
from
our
active
validator,
the
transaction
volume,
every
transaction-
that's
going
through.
Really
everything
that's
going
on
on
the
network,
and
we
really
believe
this
kind
of
transparency
creates
further
security
for
axler
and
our
solution.
H
In
terms
of
use
cases
who
would
benefit
from
axler
and
our
general
message
passing,
we
really
believe
our
the
ability
to
now
call
smart
contract
from
any
chain
opens
a
whole
new
world
of
opportunities.
Anything
from
cross
chain,
nfts
cross
chain,
ft
marketplaces,
most
defy
applications,
will
benefit
from
cross
chain
messaging
and
consolidated
liquidity.
H
We
believe
wallets
are
very
exciting
because
it
has
the
potential
to
be
the
next
web3
super
app,
creating
a
unified
experience
where
people
don't
have
to
leave
the
application.
Think
of
your
revolut
or
your
wechat
experience
before
web
3.
and
lastly,
gaming,
any
in-game
asset
nfts
can
be
moved
from
one
chain
to
another
and
you
and
then
also
interact
with
d5
application,
be
collateralized
as
a
loan,
perhaps
the
sky's
the
limit,
and
we
are
really
excited
to
work
with
aurora
and
nir,
and
the
amazing
builders
here
to
develop
the
next
generation
of
cross
chain
applications.
H
A
little
while
our
team,
our
co-founders,
sergey
and
yorigos,
are
highly
technical.
They
were
on
the
founding
team
of
algorand
and
before
that
they
both
have
phds
in
cryptography
and
computer
science
at
mit
and
waterloo,
and
they
were
actually
assistant
professors
at
that
school.
So,
given
their
technical
background,
they
really
built
a
world-class
technical
team.
We
have
over
20
engineers,
we
spent
the
last
two
years
developing
our
internal
ability
solution
and
only
in
the
last
six
months
did
we
start
adding
non-technical
hires
like
myself
to
help
this
go
to
market.
H
I
want
to
show
you
guys
some
concrete
use
cases.
That's
come
out
of
axillar,
so
osmosis,
as
some
of
you
may
know,
is
the
largest
decks
in
the
cosmos
ecosystem
in
may
of
this
year.
They
did
a
community
vote
where
they
were
looking
for
canonical
bridging
solution.
They
had
you
know
well-known
and
tribally
players
like
nomad
layer,
zero
gravity,
bridge,
wormhole,
submit
proposals,
and
ultimately
the
community
then
asked
various
questions
and
then
took
a
vote.
H
They
voted
axler
to
be
canonical
bridging
solution,
but
what
I
really
want
to
focus
on
is
the
impact
in
the
first
30
days
within
the
first
30
days,
they
had
a
30
million
of
organic
tbl
that
came
from
bridged
assets.
We
now
had
ethereum
btc
pools
in
the
cosmos
ecosystem.
For
the
first
time,
uscc
became
the
third
largest
asset,
and
now
cosmos
was
able
to
be
compatible
with
evm
based
chains.
H
H
Another
example:
axlerc
a
grassroots
project
that
came
out
of
our
grants
program
is
building
a
cross-chain
nft
marketplace
and
a
cross-chain
nft
bridge
within
the
four
months
of
them.
Building
they've
now
have
50
000
discord,
members,
40,
000,
active
users
and
they've
minted,
something
like
almost
half
a
million
nfts
across
all
of
the
various
different
networks.
H
A
H
A
Before
we
move
on
I'll,
kindly
kindly
ask
asks
western
basaraba
our
next
speaker
to
oh
you're
here.
Finally,
very
I
was
thinking
you're
lost
here
great,
so
we're
about
ready
to
proceed
with
our
next
speech.
I
just
wanted
to
announce
that
tomorrow
we
will
be
open
from
9
00
a.m.
We
will
have
some
office
hours
visit,
liapalo
zukin,
co-founder
of
near
protocol.
A
D
All
right
well,
thank
you.
Thank
you
a
lot
for
attending
here
and
thank
you
for
sticking
along
until
the
end.
Almost
the
end
of
the
talks.
Don't
worry
I'll,
try
to
not
make
it
too
complicated
and
and
yeah,
but
nonetheless
we'll
be
talking
about
reputation
here,
we're
talking
about
building
trust
in
a
decentralized
economy.
D
Why?
If
we
take
a
look
at
our
normal
economy
right
now?
Well,
it's
based
on
trust,
possibly
too
much
trust,
and
that's
why
blockchains?
You
know
decentralized,
but
we
still
need
trust
right.
The
bank
trusts
you
that
you're
going
to
pay
back
the
loan
once
you
know,
and
then
that's
that's
where
you
give
you
the
loan.
So
trust
is
an
important
tool
for
us
to
have
efficiency
in
our
economy,
but
we
don't
have
that
in
blockchains
right
at
least
not
yet
like.
We
don't
trust
each
other.
D
We
don't
know
who
is
the
real
person
who
is
not?
We
don't
know
like
anything
about
the
trustworthiness,
reputation
of
people
right
and
and
yeah
that
doesn't
work
quite
well,
so
the
more
traditional
way
that
you
can
see
that
trust
is
by
doing
kyc,
know
your
customer
verification,
so
verifying
your
users
that
they
are
legit.
However,
that's
obviously
the
total
black
sheep
in
blockchains,
because
well
it's
totally
non-private,
it's
totally
centralized
and
it
also
takes
a
lot
of
time.
So
that's
why?
D
D
Okay-
and
we
believe
we
are
we're
one
of
the
first
players
in
industry
to
be
able
to
like
get
more
of
our
verifiability
while
still
not
compromising
privacy,
and
something
I
should
have
mentioned
at
the
start-
is
that
we
just
got
a
grant
from
aurora,
so
we're
putting
on
aurora
but
but
yeah,
and
we
would
love
to
start
like
operating
and
talking
with
the
d5
apps
in
the
air
to
see
what
kind
of
verification
they
need.
So
can
we
put
the
video
please
so
before
we
before?
E
E
D
D
That
document
as
an
nfc
and
any
nfc
card
there,
so
this
is
our
mobile
app.
It
is
reading
the
id
document
right
now
using
nfc
and
in
a
couple
seconds
it's
going
to
show
you
that
your
personal
information,
like
your
photo
and
everything
else,
whatever
it
could
read
from
the
id
document
and
more
things
now.
D
The
next
step
is
to
actually
generate
a
zero
knowledge
proof
that
this
document
is
valid,
that
you're
over
18
that
you're
not
on
a
sanctions
list
or
whatever
else
you
need
to
prove
about
yourself
in
order
to
be
able
to
use
some
sort
of
dab,
defy
app
or
service
or
whatever.
So,
let's
say
we're
going
to
start
we're
going
to
start
generating
the
the
zero
knowledge
proof
that
usually
takes
some
time.
A
few
minutes
we're
working
on
making
it
better.
D
Once
it's
done,
this
is
how
proof
looks
like
it's
boring.
I
know,
but
it
doesn't
reveal
your
private
information.
That's
the
most
important
thing,
so
you
can
take
this
proof.
You
can
send
it
to
uni,
swap
you
can
set
it
to
whatever
you
want.
Whatever
accepts
this
kind
of
proof,
they
can
verify
that
you've
been
kyc'd,
but
it
doesn't
share
it
like,
but
nobody
received
your
private
information
in
the
end
and
that's
basically
what
we're
doing
in
a
nutshell.
H
D
D
So
let's
say,
we've
got
a
very,
very
simple
function
that
takes
three
numbers
and
let's
say
that
the
task
for
me
is
to
prove
to
you
that
I
know
that
a
times
b
equals
c
and
you
know
what
c
like
c
is
public
and
but
you
don't
know,
what's
a
and
b,
and
I
need
to
prove
to
you
that
I
know
that
a
times
b
equals
c,
but
without
showing
you
the
actual
a
times
b
right.
So
zero
launch
proofs.
Allow
you
to
do
this,
so
let's
say:
we've
got
this
function.
D
I
can
say
that
a
is
private
b
is
private
c
is
public
and
I
can
take
this.
I
can
put
it
into
a
magic
black
box
called
the
zero
knowledge
prover
and
it's
going
to
output
a
proof
that
looks
like
exactly
what
I
showed
you
a
couple
moments
ago.
You
send
that
proof
to
whoever
wants
to
verify
it,
and
now
they
know
for
sure
that
I
know
some
a
times
b
equals
c
okay
and
that's
pretty
cool.
So
let's
take
this
concept.
D
Let's
take
it
a
step
further
and
let's
apply
some
more
cryptographic
primitives
to
it.
So
let's
say
that
now,
I'm
trying
to
prove
something
more
complicated.
Let's
say
I
know,
jack
jack
is
some
blockchain
user
or
whatever
so
they've
got
a
public
key
they've
got
a
private
key
jack
and
I
want
to
prove
to
you
that
I
know
piece
of
information
which
has
which
has
a
signature
by
jack
okay,
but
I
don't
want
to
show
you
that
information
and
I
don't
want
to
show
you
that
signature.
D
So
what
I'm
going
to
do
is
so
I'm
going
to
do
this,
so
this
is
the
data
that
I
don't
want
to
show
you.
This
is
the
signature
that
I
don't
want
to
show
you,
and
this
is
the
public
key
of
jack,
which
you
already
know,
and
I
can
generate
a
zero
knowledge
proof
that
well
that's
the
data
I
have
is
actually
signed
by
jack
without
showing
it
to
you
and
yeah.
D
It
just
works,
and
if
we
just
take
this
a
slightly
step
forward,
that's
basically
how
audit
works
in
a
nutshell,
so
we're
so,
let's
say,
you've
got
a
passport.
This
is
data
like
your
name,
the
social
security
number
everything
else.
Then
you
got
a
signature
over
that
passport
by
the
issuing
country,
let's
say
the
u.s,
and
then
you
got
a
public
key
of
the
u.s,
and
so
I
can
prove
to
you
that
I've
got
I've
got
a
passport
which
is
legit
which
is
properly
signed
which
came
from
the
america
without
showing
you
anything
about
it.
D
So
that's
the
base
fundamental
idea
of
how
audit
works.
How
does
it
like?
How
do
we
get
this
signature
document
thing
whatever?
Well,
there's
actually
pretty
big
international
standards
of
passports
and
identity
documents
which
support
which
have
an
nfc
chip,
so
you
can
actually
digitally
read
your
passport
most
of
you
guys.
D
How
does
this?
Actually?
How
does
this
proof
actually
fit
within
the
whole
outed
model
here?
Well,
let's
say
we
got
bob
here:
bob
wants
to
use
any
swap,
or
some
swap
or
whatever,
and
some
swap
wants
bob
to
prove
that
they're
over
18,
okay,
so
bob
uses
our
app
and
they
scan
their
passport
and
our
app
generates
a
very
clever
proof
that
proves
that
bob
is
over
18
and
other
things.
D
Whatever
the
app
wants,
and
then
this
proof
gets
sent
to
our
smart
contract
on
chain
it
gets
verified
and
then
the
some
swap
the
app
gets
notified
that
hey
jack
now
can
use
your
app.
So
jack
now
can
use
the
app
and
that's
great.
However,
there's
still
a
bigger
question
to
answer
here,
because
well
you
can
verify
people
search
your
knowledge.
D
D
I'm
not
going
to
explain
how
npc
works
in
detail,
but
what
you
need
to
know
is
that
every
one
of
these
nodes
have
knows
a
piece
of
the
user
data,
but
they
all
need
to
come
together
in
order
to
learn
actually
in
order
to
actually
combine
and
like
actually
read
the
user
data
and
so
just
like
within
a
blockchain.
These
are
nodes,
so
you
can
give
them
a
protocol
to
execute
and
the
protocol
could
be.
You
guys
can't
share
the
data
to
anyone,
except
if
the
police
comes
and
asks
for
it,
for
example.
D
Well,
you
can
actually
use
this
to
generate
a
permanent,
global
decentralized
identifier
for
that
user,
so
no
matter
which
blockchain
they
use
like
no
matter
like,
if,
if
they
verify
the
same,
is
using
audit
on
avalanche
on
polygon
on
aurora
knee
or
whatever
they
could.
If
they
go
through
this
process,
they
all
they
always
get
exactly
the
same.
D
The
idea
is
exactly
the
same
identifier
and
that's
pretty
cool
if
you
want
to
have
more
reliable
reputation
models
or
like
scoring
or
being
able
to
prove
that
you
own
did
multiple
accounts
in
multiple
in
multiple
different
blockchains,
so
yeah.
I
think
this
is
the
first
story,
one
of
the
first
implementations
of
decentralized
indentifiers,
which
is
fully
sibo
resilient,
which
means
simple,
resilient
and
blockchain
agnostic,
which
means
no
matter
which
blockchain
you
use.
D
The
centralized
project
would
also
want
to
use
this
for
like
on
their
own
initiative,
if
they
want
to
do
age,
verification,
they're
selling,
for
example,
adult
content
if
they
want
to
verify
or
trust
their
borrowers
more
to
give
them,
let's
say
better
loan
terms
or
if
they
want
to
verify
that
like.
If,
if,
if
you're
making
an
institutional
poll,
maybe
you
want
to
verify
that
something
about
the
institutional
investors
in
that
poll
and
the
democratic
voting
citizenship?
Things
like
that
or
if
you
have
an
offending
user,
you
want
to
blacklist
them
forever
like.
D
D
Another
cool
thing
you
can
actually
do
is:
if
you
want
to
collect
user
insights,
you
can
do
that
in
a
way.
Here
too,
for
example,
you
can
ask
your
users
to
prove
that
their
age
falls
within
a
few
boxes.
Let's
say
you
know
less
than
80
18
to
25
25
to
40
whatever,
and
this
way
users
don't
have
to
review
their
exact
age,
but
you
still
get
to
collect
the
insights.
So
that's
cool,
though
so,
with
that
said,
there's
still
a
few
things.
We
need
to
work
out.
Obviously
it's
no!
D
It's
not
all
sunshine
and
labels
in
particular
the
most
obvious
way
that
you
can
cheat
the
system
is,
if
you
steal
someone
else's
passport
and
then
you,
you
know
you
verify
yourself
because
right
now
we
don't
verify
your
face
and
anything
like
this
because
well,
this
will
require
essentially
a
kvc
company
to
do
that
and
that's
kind
of
what
we're
trying
to
replace
here.
So
there
are
a
few
other
clever
ideas
to
use
like
extra
data
extra
source
of
information
to
make
sure
that
you
actually
own
the
password.
D
For
example,
you
could
prove
that
you
can
log
into
a
government
into
a
government
tax
account
or
some
sort
of
like
online
government
service.
That
has
your
name
on
it
and
and
there's
a
way
to
do
that,
while
still
revealing
your
like,
while
still
protecting
your
privacy,
and
you
don't
show
your
name
to
anyone
et
cetera,
et
cetera,
but
you
can
prove
that
you,
like
you,
really
are
the
person
to
do
it
to
a
good
extent.
D
That's
it
so
we
recently
got
a
grant
from
aurora,
but
we've
been
building
this
for
the
past
five
months.
We
got
a
white
paper.
We
have
a
team
of
two
developers
in
addition
to
anna
my
co-founder
over
there
and
alexi
our
advisor
over
here,
conveniently
placed
in
the
first
role
and
yeah,
so
we'll
be
publishing
the
test
version
already
in
about
three
months
and
for
this
yeah.
So
that's
so
that
that's
me
anna
alexi
yeah.
So
for
this
we
really
want
to
know
if
you
guys
are
curious
to
test
it
out.
D
We're
setting
up
with
all
the
initial
pilots
right
now,
so,
if
you
want
to,
if
you
want
to
test
out
our
koac
project,
if
you
want
to
see
if
you
want
to
like
use
this
for
your
users,
given
you
know
the
circumstances,
definitely
let
us
know
this
is
our
email
or
you
can
scan
it
or
we
also
have
a
telegram
community,
so
definitely
connect
and
yeah.
If
you
could
no.
D
E
D
Right,
well,
you
could
like
the
way
we've
been
thinking
about.
It
is
to
use
whatever
other
incentives
like
their
one
blockchains
use
to
make
sure
their
violators
are
including,
like
they
could
be
stakers,
they
could
yeah,
I
guess
mostly
stakers
or
other
kinds
of
economic
incentives
for
for
them
to
not
collude.
D
D
A
governor's
vote
and
say
well,
like
there's,
been
a
data
leak
somewhere,
and
that
means
that
not
only
like
one
or
two
or
three
validators
like
collided,
but
like
more
than
60
percent
of
them
collided.
So
that's
you
know,
that's
unlikely,
but
if
it
happens
then
you
can.
You
can
probably
just
slash
everyone
or
near.
A
A
Don't
forget
to
participate
in
our
activities.
You
still
can
get
some
airdrops
on
your
nail
near
wallet.
We
have
weeds,
we
have
puzzles.
Actually.
I
already
got
some
mirrors
and
I
think
the
I
have
like
late
answer
for
the
question.
What's
the
best,
what
for
the
best
to
use
three
years,
I
think
it's
just
best
to
keep
it
because
crypto
winter,
it's
not
forever
just
keep
it
for
crypto
spring.
A
I
Thank
you
happy
to
be
here.
My
name
is
marcelo.
I
work
with
abroad
today.
I
hope
you
are
up
for
some
code.
I
do
want
to
show
you
one
of
the
neat
functionalities
that
I
think
have
not
been
exploited,
that
much
still
on
aurora
and
it's
the
very
fact
that
aurora
is
a
smart
contractor
near.
It
means
that
it
can
interoperate
easily
with
every
other,
near
contract
out
there
without
needing
any
bridge.
So
today
I
just
want
to
deploy
a
very
like.
I
Hopefully
I
have
internet
I've
seen
the
internet
here
is
not
great,
but
hopefully
with
my
cell
phone.
I
can
try
it
to
show
you
our
contract
like
how
we
can
connect
a
contract
on
near
to
a
contract
on
aurora,
so
they
can
talk
between
each
other.
I
already
made
this
a
very
too
simple
and
small
smart
contract.
There
is
this
a
status
message
contract
on?
Oh
sorry,
not
no
models!
That's
insane!
This
is
smart
contract
on
well.
I
This
is
a
solid
smart
contract,
but
this
is
a
smart
contract
that
you
can
run
aurora.
It's
like
it's
a
kind
of
chart:
smart
contract,
it's
a
little
bit
lengthy
just
because
of
like
public
interface
just
to
talk
to
it.
But
the
main
point
is
that
you
can't
call
set
our
address
and
if
you
call
this
function
like
you
will
set
a
status
message
like
it's
like.
I
I
I
Sorry
we
are
going
to
status
message.
Okay,
so
first
we're
going
to
do.
Is
I
made
in
this
in
this
solidity
contract?
I
made
three
functions
that
I
will
be
using
today
when
it's
to
deploy
the
contract.
One
is
to
check
all
status
message
for
every
contract
out
there
and
when
it's
to
just
add
a
status
status.
Programmatically
no,
like
interface,
is
used
cli.
Hopefully
this
will
work
for
you.
You
will
notice.
This
is
just
her
hat,
so
interacting
with
aurora.
It's
like
seamlessly
the
same.
I
You
would
do
it
as
interacting
with
ethereum,
nothing
fancy
to
it.
So
let
me
go
through
it
before
I.
Actually,
I
will
be
using
near
testnet
now,
testnet
just
to
avoid
like
interacting
with
maintenance
and
real
tokens.
Just
because
it's
a
little
bit
easier
here
than
setting
up
like
you
know,
secret
keys
and
everything.
So
first
thing
is:
I
will
actually
deploy
near
contract.
I
You
can
like
this
is
just
building
the
contract.
It's
super
fast
because
I
already
built
it
before
coming
here,
but
building
the
contract
is
just
building
a
rust
contract
into
into
wasan
and
then
deploying
a
contract
in
in
near
test,
and
it's
also
just
calling
like
you
can
use
it
with
a
cli
and
it's
extremely
simple.
Okay,
this
seems
to
be
working
on
testnet.
You
get
automatically
assign
an
account.
I
We
got
this
like
dev
1658,
whatever,
with
some
tokens
into
it,
and
right
now
we
deployed
our
contract
and
we
just
initialized
it
with
this
function.
Okay,
so
I
was
doing
this
before
because
right
now
I
can
just
like
I
have
this
new
account
that
I
will
be
using
to
initialize
my
aurora
smart
contract.
I
So
the
whole
point
is
that
on
aurora,
just
to
show
you
a
little
bit
about
the
aurora
smart
contract,
how
it
will
work,
we
have
these
two
functions
set
our
other
status
or
set
near
account
id
status.
We
can
set
a
status
as
an
aurora
user
or
as
a
near
user,
okay
and
as
a
near
user.
There
is
only
one
contract
that
can
talk
with
my
particular
contract
and
then
every
user
can
interact
with
my
contract
through
this
other
contract.
I
This
is
just
how
I
design
this
app
doesn't
need
to
be
necessary
like
this,
but
it
makes
it
significantly
easier.
I
will
be
sharing
this
code
in
github
afterwards,
okay,
so
if
we
just
go
here,
we
can
oh
sorry,
jar,
her
hat,
deploy
and
I'm
just
deploying
my
contract,
and
there
is
something
weird
happening
here
that
I'm
specifying
like
near
proxy
account
id.
This
is
the
account
on
here
that
it's
authorized
to
talk
in
behalf
of
new
york
contracts.
I
Here
is
a
very
neat
part
on
aurora.
We
cannot
like
we
don't
have
this
concept
of
near
account
ideas,
but
we
do
have
the
concept
of
implicit
account
implicit
address
for
new
account
ids,
so,
basically,
for
every
account
idea
near
there
is
an
address
on
aurora
that
will
represent
you
every
time
you
interact
with
aurora
as
an
air
account.
I
So
that's
a
really
neat
in
this
case,
for
example,
just
to
show
you
this
is
my
near
account
id
it's
a
little
bit
cryptic
in
this
case,
because
it's
a
test
net
address
you
will
usually
have
like-
I
don't
know,
marcelo
lanier,
that's
near
address
and
then
for
every
others.
You'll
have
an
implicit
account
id
that
it's
derived
deterministically,
okay,
so
every
time
I
will
be
talking
with
aurora
from
these
address
here,
I
will
be
using
this
address
in
aurora.
I
So
that's
what
I
was
specifying
to
initialize
my
contract
and
right
now
it's
already
deployed.
So
let
me
use
her
code
here.
Oh
not
here
here
the
address
of
the
contract,
so
I
can
easily
like
list
all
the
messages,
all
status
messages.
There
is
a
of
course.
There
is
nothing
there,
but
I
can
say,
like
I
can
put
some
status
here.
I'm
talking
on
behalf
of
my
of
the
same
deployer
like
I'm,
using
a
testnet
account
to
deploy
to
interact
with
the
chain.
I
This
is
a
regular
output,
use
a
successful
transaction
on
our
network
happening,
so
you
should
be
able
to
get
this
hash
function
and
go
maybe
to
our.
Like
test
net
out
our
scan
and
here
intestinal
errors,
can
you
find
this
transaction
like
this
actually
took
place
on
chain,
and
this
was
set
in
my
this
was
set
in
a
status
right.
So
if
I
list
all
status
right
now,
there
should
be
at
least
one
okay.
I
First
of
all,
I
need
to
tell
to
the
near
contract,
which
is
already
created.
I
did
like
in
the
first
step,
I
deployed
a
near
contract.
I
want
to
tell
the
near
contract
that
this
is
the
contract.
It
should
be
interacting
to
inside
a
aurora
network.
So
for
doing
that
there
is
this
function.
Let
me
just
quickly
show
it
set
status
message
address.
That
is
just
a
function
that
will
tell
the
near
contract.
Okay.
I
This
is
the
contract
on
aurora
that
you
care
about
you'll
notice
that
there
is
a
lot
a
little
bit
of
boilerplate
here,
but
this
is
only
about
initialization,
I'm
just
going
through
the
whole
process,
with
all
of
you
right
now
so
set
a
status
message
message
address
and
I
will
set
the
address
that
we
care
about.
No
0x
use
a
hexadecimal,
and
this
is
a
real
contract
on
a
near
blockchain.
That's
taking
place
right
now,
like
you,
can
see
the
transaction
also
on
a
test
explorer
and
I'm
setting.
C
I
So
now
the
cool
part
is
that
I'm
setting
a
message.
Okay,
so
I'm
just
calling
I'm
setting
I'm
calling
this
a
contract.
This
is
a
near
contract.
Okay,
if
I
use
call
of
sorry
account,
this
is
the
contract
I'm
interacting
to
on
near
blockchain,
it's
this
kind
of
cryptic
contract
and
I'm
just
calling
it
from
account
of
my
own,
which
is
called
ide.testnet.
I
So
I
will
set
a
status
message
from
id.testnet
and
hopefully
it
will
be
set.
Sorry
not
this
said
message,
okay,
so
I
will
be
calling
the
account
of
the
contract
on
near
and
to
setting
my
status
on
on
the
aurora
smart
contract.
Okay,
so
super
cryptic
stuff
happening
here.
The
fact
is
that
aurora
will
spit
out
a
few
bytes
that
we
don't
need
to
understand
right
now.
I
The
point
is
that
this
is
a
successful
transaction
that
took
place
and
if
we
go
to
the
transaction
and
see
what
happened
you'll
see
that
there
is
a
transaction
that
was
created
by
ide.testnet,
which
is
my
account.
I
was
calling
the
account
that
I
just
deployed,
which
is,
will
be
working
as
the
proxy
between
id
and
the
account
and
near,
and
then
you
see,
okay,
I'm
sending
this
message
and
then
this
contract
here
is
making
a
call
to
aurora
contract.
G
I
Calling
over
a
contract
with
the
right
parameters
to
set
a
status
message
on
behalf
of
ide
the
test
net.
So
if
we
go
back
to
the
part
of
id
the
testnet
that
I
call
list
messages
you'll
see
here,
okay,
there
are
two
status
already
set.
The
first
one
is
the
first
we
said
hello
at
cc,
and
hopefully,
okay.
There
is
a
second
status.
It's
coming
from
ide
to
testnet.
I
I
That
I'll
show
you,
but
basically
the
core
part
is
that
we
are
making
a
cross-contract
call
where
we
specify
which
contract
we
want
to
call
how
money
weigh
like
how
many,
if
we
want
to
pass
it
right
now.
No,
if
at
all,
we
don't
care
about
it,
it's
just
zero,
and
then
we
encode
the
arguments
of
what
we
want
to
do.
I
We
are
using
the
same
format
that
ethereum
is
using,
because
that's
exactly
what
our
supports
it's
a
avi
encoding
and
right
now,
I
did
all
the
encoding
by
myself
just
by
hand
here:
okay.
Yes,
this
is
how
I'm
coding,
like
I'm
calling
this
function
said
near
account,
release
status,
so
I
will
not
go
deep
into
api,
but
we
can
discuss
it
later.
If
you
are
interested
here,
it's
me
use
building
by
hand
the
the
arguments
and
then
the
particular
call
it's
in
a
very
special
way.
I
A
A
A
It
will
be
a
live
broadcast.
We
are
open
our
doors
at
nine,
starting
with
a
coffee,
some
finger
food.
After
that
you
can
have
a
nap
on
our
beautiful
terrace
and
1pm.
We
will
start
our
office
hours
with
yapolasukin
the
founder
near
at
2.
We
are
starting
office
hours
with
oliver
baker
from
grant's
pro
grants,
program
manager
and
also
