Yes,
hello.
Everybody
welcome
welcome
to
our
office
hours.
Today
we
will
be
talking
about
essentially
random
stuff,
answering
young
questions
from
participants.
I
believe
a
lot
of
our
participants
to
be
are
still.
You
know,
approaching
the
master
class
they
just
finished,
which
was
a
presentation
on
how
we
built
it
of
the
slate
service,
which
I
really
recommend
you
guys
watch
online
when
it
appears.
A
So,
let's
see
if
we
have
any
questions,
we
don't
have
anything
yet.
So
let
me
share
my
screen
real
quick.
Well,
while
we're
waiting,
I
guess
and
see
where
we
are
with
the
slingshot
competition
towards
about
that.
For
those
of
you
who
don't
know
the
century,
competition
is
essentially
the
second
phase
of
our
space
race
activities,
which
started
back
in
august
almost
actually
not
almost
five
weeks
ago.
So
over
a
month
ago,
we
started
first
with
a
lot
of
minor
strength
to
onboard
voltage
storage.
A
We
did
a
lot
of
debugging.
We
did
a
lot
of
various
adjustments
tuning.
We
even
implemented
something
that
ethereum
has
wanted
to
implement
for
year.
I
believe
now
their
proposal
for
fee
scheduling
and
how
to
increase
the
throughput
of
the
network,
and
we
just
went
ahead
and
implemented
this
ourselves
and
folks
are
observing
how
it
works
in
production.
A
Now
we
are
focused
on
trying
to
streamline
how
you
put
data
on
filecoin
as
a
client.
So
slingshot
is
this
competition
for
clients
who
are
essentially
trying
to
put
what
we
call
authentic
datasets
on
the
filepoint
network.
An
authentic
data
set
can
be
anything
that
is
considered
useful
or
very
or
culturally
significant,
or
something
of
that
matter
to
you
know
to
to
a
general
participant
in
the
in
the
in
the
falcon
network.
A
So
we
are
not
encouraging,
in
fact
we're
actively
discouraging
people
to
just
fight
dev
zero,
that
we
run
them
into
powercoin.
We
are
actually
asking
people
to
put
stuff
on
the
network
and
we
are
already
one
weekend.
This
competition
starts
exactly
seven
days
ago,
and
by
now
we
are
actually
doing
pretty
well.
We
already
have
32
terabytes
of
data,
that
is
usable
by
others
placed
on
the
on
the
pipeline
network.
A
This
data
is
also
being
is
accompanied
by
an
app
that
the
teams
competing
this
in
this
phase
of
space
race
are
putting
together
an
app
that
allows
you
to
browse
what
is
available
on
in
this
particular
set
of
data
descriptions
outline
it
might
be
just
data
for
download
like.
I
know
that
there
is
a
person
putting
together
a
bunch
of
podcasts
and
just
putting
them
on
on
powerpoint,
and
there
will
be
a
portal
where
you
can.
A
You
know
see
what
is
being
available
and
if
you
want
actually
pull
them
out
of
our
point
with
your
clan
or
with
your
power
gate
mode,
all
the
way
to
things
like
slave,
which
are
essentially
it's
difficult
for
me
to
to
describe
slate,
because
it's
so
awesome,
but
what
slate
offers
is
essentially,
the
user
content
that
is
being
created
normally
was
hosted
on.
Ipfs
is
now
also
backed
up
to
file
point
for
all
participants
in
the
you
know
in
the
slave
playground,
so
yeah.
A
All
right,
so
we
don't
have
any
questions
yet.
So
let
me
let
me
keep
talking,
I
guess
about
where,
where
space
is
right,
now,
let's
just
go
to
the
to
the
through
the
port
and
see
what
else
is
there?
So,
as
I
was
saying,
we
kept
the
two
terabytes
of
data
already
onboarded.
We
also
have
some
extra
metrics
here
we
have
average
data
for
participants
when
we
say
participant.
A
A
Oh
here
they
are
so
342
participants
and
for
participant
the
average
amount
of
data
is
97
gigabytes,
almost
100
gigabytes
each,
which
is
pretty
cool
again
to
stress.
We
are
in
the
very
beginning
of
this
competition
folks
are
still
figuring
out
how
to
set
things
up,
how
to
get
either
how
to
get
set
up
with
power
gate,
which
at
this
point
is
the
recommended
way
to
try
to
interact
with
coin
if
you're,
just
beginning
or
trying
to
sell
their
local
lotus.
Note
and
people
are
showing
how
to
deal
with.
A
You
know
how
to
deal
with
minor
selection,
how
to
essentially
figure
out
who
to
make
deals
with
they
were
figuring
out
how
to
arrange
their
data
and
so
on
and
so
forth.
So
this
number
might
seem
small,
but
it's
actually
pretty
significant
and
we
have
average
deal
size.
So
a
deal
in
foul
point
context
is
a
one
to
one
transaction
between
a
client
and
a
minor.
So
you
have
all
kinds
of.
A
Steps
that
you
take
as
a
client
to
figure
out
like
who
do
I
want
to
start
with,
but
when
that
make
your
selection,
it
can
be
one
minor.
It
can
be
several.
In
fact,
this
competition
encourages
people
to
store,
with
at
least
three
miners
to
be
qualified
for
for
the
for
the
price
pool
and
at
the
end
of
the
day,
every
set
of
data,
be
it
a
file
or
bit
attack,
not
normally
this
dag.
A
Three,
just
like
we
normally
do
in
ipfs
if
you're
familiar
with
this
on
the
ipvs
gateway,
and
then
all
of
this
is
put
into
a
proposal
with
associated
payment
to
a
miner,
and
this
called
a
deal
so
the
average
deal
has
been
140
megabytes
of
data.
Some
of
them
are
relatively
large.
Some
of
them
are
small,
so
it's
just
average
and
we
have
our
hundred
thousand,
I'm
sorry
or
a
hundred
thousand
and
ten
deals.
I'm
sorry,
110
000
deals
already
on
the
network.
A
So,
for
example,
let's
take,
I
don't
know-
might
think
12
pen,
whatever
it
is,
let's
find
out
so
we're
going
to
click
on
them,
and
it's
going
to
take
us
to
okay,
it's
going
to
take
us
to
a
place
which
is
unfortunately
well
not
unfortunately,
unfortunately,
I
do
not
know
the
language
to
do.
Is
this
implemented?
A
A
A
A
A
Machine
learning
database
or
something
like
that,
and
they
have
the
individual
files-
and
here
is
the
miner
with
which
they
made
the
particular
deal,
and
those
are,
I
believe,
those
would
be
right.
Those
would
be
the
payloads
id.
So
you
should
be
able
to
go
to
this
miner
and
ask
for
this
particular
deal
and
be
able
to
see
what
this
does.
A
When
would
you
use
lotus
as
a
developer?
So
this
is
an
interesting
question
today
we
essentially
are
steering
people
for
the
time
being
to
powergate,
about
which
there
was
a
master
class
about
two
days
ago.
I
believe
on
monday,
which
powergate
is
a
managed
solution
that
bundles
an
ipfs
mode,
a
lotus,
node
and
I'll
explain
a
moment
what
what
voltage
is
and
an
orchestrated
daemon
that
basically
allows
you
to
interact
with
with
the
5.
network.
A
Just
like
just
like
you,
you
would
want
to
interact
with
it
in
in
a
more
pointing
tv
kind
of
way,
with
a
nice,
you
know,
ux,
chrome
and
so
on
and
so
forth.
So
let
me
step
back
and
and
and
talk
a
little
bit
about
what
lotus
actually
so
lotus
is
our
initial
reference
implementation
of
falcoin.
This
is
the
software
that
currently
is
powering
the
space
race
network.
A
After
our
liftoff
date,
which
currently
is
in
about
two
weeks,
we
are
pretty
confident
we
are
going
to
hit
it,
but
you
know
blockchains
that
had
so.
Hopefully
everything
will
go
just
fine
and
so
lotus
is
this
piece
of
software
that
you
could
get
it's
all
open
source.
I
compile
it
yourself,
you
can
build
it
on
even
something
as
your
macbook
and
you
will
be
able
to
actually
interact
with
your
popcorn
network.
A
There
are
a
few
specifics
of
how
you
need
to
build
it
for
the
performance
to
be
acceptable
and
also
you
want
to
start
your
synchronization
to
the
chain
for
the
time
being
from
a
trusted
snapshot,
because
we
haven't
done
all
the
work
yet
to
optimize
syncing
from
from
scratch.
So
basically
you
just
start
to
know
and
you
go
to
the
network
and
you
get
all
the
data.
That's
out
there
about
about
our
blockchain.
This
currently
takes
a
little
bit
longer
than
we
would
like.
A
So
in
the
documentation
you
will
find
how
to
get
essentially
up
and
turning
in
about
40
minutes
with
lotus
from
download
through
compilation
to
configuration
through
getting
the
chain
to
sync
with
the
present
with
the
chain
and
being
able
to
you
know
to
to
interact
with
with
the
network
in
real
time.
So
when
you
thought
it's
a
developer,
if
you
are
comfortable
with
all
the
steps
that
I
outlined
and
you
are
interested
in,
you
know
in
thinking
good
things,
you
definitely
should
give
lots
of
training.
A
So
you
could
you
if,
if
you
want
to
get
started
really
quickly,
then
our
current
recommendation
is
to
use
a
power
gate
note,
because
a
lot
of
the
a
lot
of
the
portions
that
I
of
the
activities
I
just
described
already
done
for
you.
So
the
the
nodes
are
computed
correctly.
There's
already
a
warm
ipfs,
warm
cache,
ipfs
node
running
right
next
to
your
lotus
node
and
you
can
literally
pull
stuff
from
the
wider
internet
via
ipfs
and
put
the
powerpoint.
A
You
can
use
this
ipfs
node
as
the
cache
between
file
point
and
your
user.
So
whenever
you
saw
something
on
five
point,
you
don't
have
to
retrieve
it
right
away.
If
you
already
got
it
in
your
cache
so
yeah,
it
basically
depends
on
your
level
of
interest
in
the
functionality
of
a
point
or
how
powerpoint
actually
is
built,
and
it
also
depends
on
how
exactly
you
want
to
use
the
network.
A
A
You
want
to
follow
the
documentation
pretty
closely
because,
as
I
said,
there
are
caveats
in
how
you
build
it.
You
almost
certainly
want
to
have
a
rest
locally
and,
in
addition
to
go
so
let
me
step
back
a
little
bit.
Falcoin
has
essentially
multiple
parts,
one
of
which
is
the
proof
system
which
ensures
that
which
basically
takes
care
of
all
the
crypto
magic,
so
to
speak.
That
allows
a
node
to
allows
a
minor.
I'm
sorry
allows
a
miner
to
prove
to
the
network
to
to
an
anonymous.
A
A
One
of
them
is
plus,
but
all
of
them
are
using
the
same
proof,
system,
module
and
taking
care
of
compiling
this
part
is
pretty
important,
because
if
you
don't
compile
it
the
right
the
right
way
with
all
the
cpu
options
on
your
machine,
if
you're
running
enable,
then
you
will
have
a
lot
of
performance
issues
and
unfriendly
things
like
that.
So
you
want
to
compile
correctly.
A
So
of
course
this
takes
a
lot
of
a
lot
of
discretes,
so
you
want
to
make
sure
that
your
iosub
system
is
is
relatively
decent
lotus.
Currently,
just
the
note
is
a
little
bit
hungry
in
terms
of
memory,
so
you
probably
want
to
make
sure
that
you
have
about
two
peaks
of
memory
available
for
it
to
go.
To
this
thing,
16
is
still.
Okay,
eight
is
like
very
hard.
It
will
be
swapping
a
lot
back
and
forth
and
the
chainsync
I
already
spoke
about.
You
basically
need
to
at
this
stage.
A
We
recommend
that
you
just
download
one
of
our
snapshots
and
we
are
working
on
signing
them
correctly
and
and
basically
ensuring
that
both
the
snapshots
are
quicker
to
download
than
there
right
now
and
that
they're
verifiable
by
external
means
that
it
was
a
protocol,
labs
or
another
trusted
party
that
you
produce
in
snapshots
and
yeah
other
than
that.
Yeah
lotus
is
just
like
any
other
whole
program
and
it
runs
pretty
well
yeah.
So
those
are
for
the
caveats.
A
Yeah,
so
I
guess
I
guess
everybody
was
pretty.
I
guess
everybody
was
pretty
blown
away
by
the
by
the
state
presentation
earlier
right
before
these
office
hours.
I
actually
don't
see
any
questions
at
present,
yeah
jason.
What
do
you
think?
Should
we
give
it
another?
I
don't
know
five
minutes
or
folks
are
seemingly
busy
doing
other
things
and
participating
in
the
sensual
competition
yeah
finish
up
whenever
you're
done,
but
we
can
give
a
bit
of
extra
time.
A
A
A
I
would
encourage
you
to
check
out
our
series,
or
around
slingshot,
called
how
we
built
this,
where
various
folks
would
be
talking
about
various
challenges
that
they
ran
into
when
trying
to
do
things
exactly
for
space
race,
two,
both
in
terms
of
arranging
data
or
collecting
data
or
figuring
out
how
to
how
to
learn
a
lot
of
snow,
steady
and
things
like
that.
So
a
lot
of
various
reports
from
the
field
so
to
speak
and
yeah
and
yeah
in
our
in
our
chat.
