A
The
world
is
flat
and
it's
divided
and
parcels
of
land,
on
top
of
which
you
can
use
JavaScript
or
typescript
to
build
your
experience
and
have
visitors
visit
your
little
piece
of
land
I'm,
going
to
be
talking
a
little
bit
about
the
past.
What's
been
going
on
in
2018,
then
give
you
five
nuggets
of
what
we're
working
on
right
now
and
then
a
road
map
for
this
year,
so
first
2019.
A
This
is
also
going
to
lead
me
to
talk
about
how
I
heard
about
the
graph
and
became
involved
with
the
project.
We
launched
a
marketplace
for
NF
T's
and
year,
C
20s
in
April,
and
since
then,
we've
seen
about
60
million
u.s.
dollars
worth
of
tokens
trading
hands
through
this
decentralized
marketplace
application.
A
A
The
first
thing
that
we
thought
was
going
to
be
a
huge
problem
is
gas,
but
because
it's
a
little
bit
an
affordable
right
now,
I'm
from
gas,
the
gas
required
to
transfer
a
piece
of
land
which
is
or
NFT
representing
a
parcel
of
land
started
at
around
$20,
almost
$30
at
the
beginning
of
the
year,
but
quickly
came
down.
I
call
this
the
low
usage
of
a
film
as
subsidizing
the
cost
of
our
offer
ecosystem
that
yeah
so
because
land
is
so
expensive.
A
A
Building
this
distributed
application
was
how
to
create
a
good
user
experience
for
the
user,
how
to
convey
perfectly
what's
going
on?
What's
the
current
state
of
your
nft?
What's
the
current,
what
are
the
assets
that
I
have?
How
are
my
transactions
doing?
This
took
us
quite
a
long
time
to
figure
out
by
the
middle
of
the
year
we
already
we
evolved,
or
language
and
or
vocabulary
along
the
rest
of
the
applications
and,
together
with
madam
asked
within
coming
together,
and
we
found
a
common
language.
So,
oh.
A
Okay,
cool
another
thing
that
we
had
to
deal
with
both
in
the
contract
level,
as
well
as
in
the
distributed
application
in
the
front
end,
was
transactions
that
may
take
a
lot
of
gas.
One
thing
that
you
were
able
to
do
in
one
of
these
options
that
we
had
was
to
select
multiple
land
parcels
and
because
the
gas
cost
for
creating
or
transferring
land
parcel
is
too
high.
It
may
exceed
the
total
gas
that
you're
allowed
to
use
in
a
block
of
a
theme,
and
the
other
problem
was
querying
well
three
to
figure
out.
A
What's
the
current
state
of
the
world
in
this
map
of
90
thousand
or
so
parcels,
if
we
have
to
worry
for
every
field,
will
we
will
be
talking
about
minutes
just
for
a
simple
display
of
the
whole
map
and
those
were
too
many
queries.
So
we
came
up
with
a
very
centralized
opens
open
source,
a
API
server
that
computes
all
of
that
in
like
70
milliseconds
or
whatever.
A
This
is
going
to
sound
very
familiar,
but
we
process
all
the
events
set
of
contracts,
it's
about
two
hundred
and
fifty
thousand
contracts.
Right
now
we
apply
some
update
rules
to
database.
We
expose
an
HTTP
API
and
we
consume
that
from
the
front
end.
We
also
had
a
lot
of
issues,
handing
rigs
and
eventually
we
fixed
everything,
but
this
was
a
lot
of
work
for
our
team,
which
was
actually
I,
should
be
a
little
bit
more
concentrated
on
building
a
3d
world,
but.
A
Already.
It's
all
pure
information,
we're
posted
to
solve
a
lot
of
problems
that
don't
require
Oracle's
into
the
real
world
and
where
we
can
experiment
with
automated
automating
most
of
everything
through
smart
contracts.
I
didn't
mention
this,
but
we
collaborated
with
ripio
in
2018
to
provide
the
first
blockchain
based
virtual
reality,
mortgages
where
the
collateral
is
the
NFT
that
you
are
buying
and
you
get
a
loan
based
on
that
you
come
by
in
installments,
a
piece
of
land
so
we're
working
and
making
it
cheaper
to
acquire
land
or
at
least
more
accessible.
A
A
We've
got
an
approach
of
five
steps.
So
first,
when
you
enter
the
decentraland
experience,
you're
faced
with
a
game
that
has
no
cryptocurrencies
involved,
but
as
you
progress
along
the
game,
you
see
that
there
are
some
scar
side
them
so
like
unique
avatars.
This
is
very
well
known
in
the
mobile
game
industry.
A
Another
nugget
of
how
the
centrum
works
is
that
we
are
working
with
two
sources
of
scarcity.
I
call
this
like.
On
the
one
side,
we've
got
a
marketplace
from
the
players:
attention
which
is
the
supply-side.
Our
and
we've
got
the
scenes.
Creators,
creativity,
which
is
the
demand
side
of
this
market
place
of
entertainment
inside
of
the
centrum,
and
we're
focused
on
the
players
attention
because,
as
users
go
around
the
world,
the
land
that
users
visit
the
most
it's
the
land
that
we
expect
to
be
more
valuable.
A
So,
in
some
sense,
when
I
show
you
this
heat
map,
this
is
a
the
main
area,
the
central
area
of
the
central
and
when
I
show
you.
This
heat
map
is
the.
Is
this
the
marketplace
for
a
piece
of
land,
or
he
said
the
number
of
unique
visits
that
every
parcel
has
that's
what
I
mean
by
having
or
NFT
token
land
encoding
the
attention
of
all
of
our
users?
A
We
don't
have
a
need
for
market
seller
reputation
as
long
as
as
long
as
the
exchange
happens
on
chain.
There's
no
way
that
I
can
either
the
contract
is
broken
or
the
trail
will
happen.
So
I
can't
possibly
accumulate
reputation
about
being
a
good
seller,
because
the
state
of
the
goods
will
always
be
the
same.
A
A
We
started
trying
to
solve
the
problem
by
one
of
the
frequent
ly.
Question
frequently
asked
questions
that
we
get
is
whether
I
can
use
my
own
avatar
inside
of
the
virtual
world
and
in
order
to
solve
this
and
also
providing
a
tool
for
the
seen
creators
to
have
a
say
in
the
aesthetics
of
their
parcel
like.
A
If
my
parcel
has
a
medieval
setup
and
somebody
comes
dressed
as
robot,
then
it
may
be
detrimental
for
the
experience
so
we're
working
calling
on
creating
these
sets
of
avatars,
where
a
bunch
of
3d
models
can
be
grouped
together
in
the
shape
in
in
a
set
that
shares
a
common
aesthetic,
and
this
set
can
be
created
by
anybody
and
it
and
whomever
creates
a
set,
can
pick
the
parameters
of
the
bonding
curve
of
the
DCR
I'm
sorry.
This
is
a
little
bit
advanced
if
you
are
not
familiar
rised
with
a
TCR
concept.
