From YouTube: ESPA Module 3D - Lotus Components
Description
Stu Berman (CTO) with PiKNiK discusses the Lotus Components including Lotus Client, other Clients, and other Gateways at the Enterprise Storage Provider Accelerator (ESPA) bootcamp week that took place in February 2022.
Data is growing at an incredible speed and much of this data is archived and/or simply lost by enterprises. Our program will accelerate net-new Enterprise Storage Providers into the ecosystem, using a Web3 protocol with an impressive incentive model called Filecoin.

A
A
First
thing
we'll
go
into
is
the
lotus
node,
the
lotus
node
handles
blockchain
and
wallet
processes.
The
lotus
node
is
also
capable
of
acting
as
a
lotus
client
that
is
sending
deals
to
other
file
coin
based
storage
providers
that
accept
deals.
The
detailed
document
also
describes
configuring,
the
full
lotus
node
as
part
of
the
storage
provider
system.
A
The
lotus
node
may
be
run
on
its
own
hardware
or,
as
part
of
a
lotus
miner
instance
for
an
enterprise
configuration
multiple,
independent
lotus
nodes
are
recommended
to
prevent
resource
exhaustion
and
the
possibility
of
the
lotus
chain
getting
out
of
sync.
In
the
slide.
You'll
see,
we've
circled
the
lotus
node
with
a
bright
red
box.
A
A
The
lotus
minor
is
the
node
that
handles
scheduling
tasks
and
storing
sealed
data.
Currently,
the
lotus
miner
process
handles
daily,
proving
also
called
window
posts
and
winning
block
rewards
also
called
winning
posts.
The
prime
function
is
to
handle
the
scheduling
of
ceiling
tasks
by
ceiling
workers
and
long-term
data
storage.
There
can
only
be
one
minor,
node
per
lotus
miner
process
once
the
customer
data
is
properly
sealed
and
stored.
Your
primary
concerns
are
ensuring
that
each
sector
is
successfully
proven
every
day
and
that
you
do
not
lose
any
block
awards
as
a
result
of
resource
starvation.
A
Every
24
hours
each
sector
is
checked
using
wd
post,
which
takes
a
sample
of
the
data
and
compares
it
to
the
expected
computed
values.
If
a
single
sector
is
checked
and
is
found
to
be
at
fault,
then
the
whole
deadline
fails
and
you
fault
the
whole
deadline,
regardless
of
how
many
sectors
are
in
it.
There
are
maximum
of
48
deadlines
per
day
in
a
24-hour
period,
giving
you
at
least
30
minutes
to
prove
each
deadline
and
all
the
sectors
that
are
in
it.
A
You
can
manually
terminate
a
single
sector
within
a
deadline
if
you
are
unable
to
repair
or
replace
that
sector.
This
so-called
proving
function
is
the
heart
of
the
file
coin
system
that
ensures
that
customer
data
is
kept
safe
and
untampered
with
today.
Some
storage
providers
have
backups
of
the
data-filled
sectors
and
they
use
that
to
replace
bad
sectors
with
a
distributed
system
of
storage
providers.
It
is
expected
that
other
storage
providers
will
also
have
replicas
of
the
same
data
and
that
repair
can
take
place
across
the
file
coin
network
without
the
need
for
manual.
A
Backup
processes
in
the
near
future
expect
to
see
that
separate
nodes
for
winning
post
and
window
post
can
run
so
as
not
to
affect
one
another,
something
that
will
be
highly
recommended
for
enterprise
storage
providers
notice
that
lotus
miner
node
does
not
need
to
be
directly
exposed
to
the
internet
as
it
is
entirely
internal
or
private
and
improves
the
security.
Posture
of
your
system
also
notice
that
the
storage
system
is
integral
with
the
lotus
miner.
A
A
A
The
market
node
is
required
to
have
inbound
internet
access
to
interact
with
deal
markets
when
deal
requests
are
offered
to
the
market
node
upon
acceptance
of
a
deal,
data
in
the
form
of
pre-formatted
car
files
is
transferred
either
automatically
or
manual.
That
is
offline
deals
to
the
market.
Node
development
is
now
underway
for
the
next
generation
of
market
node,
with
enhanced
features
and
scale
out
capabilities,
and
then
we're
going
to
talk
about
lotus
worker
nodes.
A
Lotus
ceiling
workers
are
expected
to
take
pre-formatted,
32gb
or
64-gib
car
files
and
process
them
in
such
a
way
as
to
prove
po-rep.
That
is
proof
of
replication
into
an
encoded
sector
that
we
call
a
sealed
sector.
The
sealing
process
begins
with
the
deals
in
form
of
one
or
more
car
files
being
added
to
a
sector.
A
In
today's
version
of
the
market
node,
the
scheduler
will
allow
the
market
node
to
send
the
data
transferred
directly
to
a
worker
node.
With
the
add
piece
process
running,
the
data
will
not
flow
to
the
lotus
miner
until
the
sealing
process
is
complete,
whereby
it
will
be
moved
to
the
storage
system
through
the
lotus
miner,
workers
will
be
scaled
out
in
a
variety
of
fashions
depending
upon
the
enterprise
storage
provider's
design.
A
Workers
can
also
be
organized
as
ceiling
clusters
that
serve
different
lotus
miners.
When
needed.
A
file
coin
storage
provider
needs
to
keep
the
lotus
node
miner
and
storage
system
running
24x7
in
order
to
maintain
proof
of
storage,
but
the
workers
and
the
market
node
they're
only
needed
when
there
are
deals
or
sealing
tasks.
That
is
once
a
miner
or
storage
system
is
at
capacity
and
at
a
practical
level,
the
market
and
worker
nodes
can
be
significantly
scaled
down,
as
there
will
be
rare
need
to
replace
expired
sectors
at
those
times.
A
These
are
by
twin
quasar
called
cid
gravity,
and
this
one
is
about
deal
management
and,
as
you
can
see
from
the
screen,
you
have
a
variety
of
factors
that
you
can
use
to
price
various
deals.
You
can
price
by
whether
a
deal
is
verified
or
unverified
by
the
size
by
the
duration,
and
so
you
can
have
multiple
rules
based
on
different
criteria
for
a
set
of
deals
and
of
course
you
can
have
multiple
clients
with
multiple
pricing
structures.
So
you
can
pre-arrange
pricing
for
different
clients
based
on
the
the
factors
that
are
important
to
you.
A
Another
tool
they
produce
is
called
farcaster.
This
one's
really
used
to
operationalize
your
system.
There's
both
a
series
of
monitoring
tools
that
are
part
of
this,
as
well
as
metrics
of
your
storage
provider
system.
That
can
give
you
a
sense
of
the
the
sort
of
profit
or
loss
you
might
have,
based
on
what's
happening
on
your
variety
of
minors.
