A
The
DAP
network
is
a
network
of
third-party
service
providers,
independence
of
all
kinds
that
offer
services
to
daps.
It's
a
decentralized
network,
but
liquid
apps
doesn't
reduce
the
code
and,
as
such
you
know
as
an
employee
of
liquid
apps,
obviously
I'm
going
to
be
promoting
them
all
the
time
promoting
the
services,
all
the
time,
I
think
they're
great.
That's
why
I
joined
and
I
also
joined,
because
I
care
about
building
scalable
DAPs
and
that's
what
they're,
enabling
right
now
adapts,
have
high
resource
costs,
no
matter
what
blockchain
you're
on
they
have
an
inefficient
development
lifecycle.
A
A
We
need
trustless
services
in
order
to
keep
taps
decentralized
in
order
to
keep
them
immune
to
compromise,
to
censorship,
to
attacks
to
things
like
that,
because
it's
no
good
just
to
have
your
smart
contract
decentralized,
that's
the
most
important
part,
but
if
a
bad
actor
can
just
come
and
take
down
your
front
end
or
whatever
your
app
is
effectively
dead,
I
know
that
someone
else
could
spin
up
another
front
end,
but
that'll
take
time.
It
might
not
happen.
Well,
liquid
apps
is
interested
in
having
trustless
services
all
the
way
up.
A
The
stack
we're
not
just
the
smart
contract,
but
every
other
part
of
an
app
stack
from
the
backend.
All
the
way
to
the
front
end
is
decentralized
trustless.
So
the
tap
network
is
a
middleware
layer
where
there's
this
free
market
of
services
that
service
providers
can
write
their
own
services.
Anyone
can
offer
any
services
they
want
to
daps
and
it
sits
between
the
blockchain
and
the
DAP.
A
So
from
the
dabs
perspective,
the
blockchain
has
a
bunch
more
features
that
it
never
had
before,
which
is
fantastic
features
like,
and
these
are
only
some
liquid
accounts:
free
access
for
users,
vram,
cheap
storage
for
DAP,
so
we're
dressing
some
resource
problems
that
we've
seen
on
block
chains
before
v,
cpu,
which
isn't
listed
here.
That's
computation,
things
like
AI
and
machine
learning
and
intense
computation
can
now
be
performed
with
minimal
cost.
Liquid
Oracles,
that's
decentralized.
A
Data
feeds
like
grabbing
API
data
from
the
internet
or
getting
a
whole
website,
or
even
accessing
information
on
another
blockchain
in
your
yo
smart
contract.
You
can
look
at
what
the
latest
Bitcoin
activity
is,
or
aetherium
activity,
or
whatever
blockchain
you'd
like
and
pull
it
in
and
act
on
it
using
liquid
Oracles,
liquid
scheduler,
decentralized
timed
events.
If
you've
been
building
on
EOC,
you
know
that
deferred
transactions
kind
of
the
default
way
for
yost
apps
to
do
scheduled
and
recurring
tasks.
They
aren't
guaranteed
to
work
right.
A
They
aren't
guaranteed
to
trigger
and
they're
kind
of,
a
pain
to
work
with
and
what's
more
they've
been
deprecated
now
in
the
latest
version
of
EOS
they're
going
away
so
they're
not
even
an
option
anymore,
but
you
need
to
be
able
to
schedule
tasks.
You
need
to
be
able
to
have
recurring
tasks.
You
need
to
be
able
to
schedule
updates
to
your
user
or
you
know,
game
events
or
a
data
updates
for
some
kind
of
price
feed.
A
Whatever
you
will,
you
need
to
be
able
to
do
that,
so
liquid
scheduler
allows
you
to
do
scheduled
events
in
a
decentralized
way,
and
all
of
these
things
and
many
more
services
like
liquid,
Authenticator
liquid
log
liquid,
lends
liquid
storage.
There
are
several
more
there
in
various
stages
of
development.
They
are
all
made
easier
to
work
with
and
easy
to
implement
in
adapt
using
the
Zeus
software
development
kit.
Of
course,
these
services
work
in
conjunction.
A
You
could
have
liquid
scheduler
recurring
requests
for
some
data
that
liquid
Oracle's
actually
retrieves,
and
then
the
data
is
used
on
multiple
block
chains,
with
liquid,
linked
and
stored
in
cheap,
accessible
storage
with
vram.
How
does
this
work?
Well,
the
dab
service
providers,
network
of
like
I,
said
independent
third-party
free
market
providers.
They
decide
what
services
to
offer
and
they
decide
the
prices
to
offer
the
mat
and
other
details
like
SLA
s
and
they're
all
around
the
world.
A
Anyone
can
spin
up
a
DAB
service
provider,
start
offering
services
start
getting
people
to
stake,
tab
to
them
start
earning
inflation
on
that
DAP.
There's
no
review
process
approval
process.
Again
it's
a
decentralized
free
market
and
daps
can
pick.
Let's
say,
there's
two
DSPs
here
they
offer
various
services.
Daps
can
select
which
services
from
which
providers
they
want
to
use
and
as
I've
hinted
at
before,
although
we'll
be
focusing
on
AOS.
A
Dsps
can
run
on
other
yeoseo
chains
and
dabs
can
now
run
across
chains
with
DSPs,
acting
as
a
sort
of
decentralized
translator
between
chains
enabling
full
cross
chain
ability,
not
just
token
transfers,
but
data
transfers,
sharing
data
acting
across
chains
deploying
contracts
across
chains
doing
all
sorts
of
things,
because
we
believe
the
future
is
multi
chain.
If
you're
running
an
app
on
aetherium
adapt
on
aetherium,
because
you
like
aetherium
consensus,
and
you
really
can't
do
the
computation
you
need
to
do
on
aetherium,
it
would
be
far
too
expensive.
Gas
fees
would
be
through
the
roof.
A
So
if
I,
like
the
consensus
model
of
aetherium
but
I,
want
certain
aspects
of
EOS
and
certain
aspects
of
hypothetically
Tron,
all
right
I
want
certain
aspects
of
those
blockchains
I'm
free
to
do
that
now
and
those
blockchains
are
free
to
focus
on
what
they
are
good
at.
Without
limiting
my
dap
to
only
one
set
of
features.
That's
the
dab
network.
In
short,
we're
gonna
start
covering
some
dab
services.
