Description
In an ideal world, we anticipate pitfalls before ever encountering them. Hyperledger Fabric is a versatile, modular protocol, but it can also requires deep expertise to use. In this Hyperledger Foundation member webinar, specialists from Catalyst Blockchain Platform by IntellectEU offer hard-won lessons from extensive work with blockchain networks in production.
Presentation: https://www.hyperledger.org/learn/webinars/hyperledger-in-depth-with-intellecteu-worst-mistakes-to-avoid-when-creating-managing-your-hyperledger-fabric-network
In the “Hyperledger In-depth with… .” series, Hyperledger members share learnings from their projects and try to answer all the hard questions about the pains of working with DLTs. It is not yet another webinar: participants will be encouraged to take part, come with prepared questions and voice opinions. Expect live demos and tutorials, stories from the battle field and hopefully some heated discussions. Let’s get out of the zoom fatigue and engage to share experiences and build a stronger community.

broadly,
you
can
find
our
code
of
conduct
on
our
website
and
also
on
our
wiki.
A
Here
at
the
hyperledger
foundation,
we
followed
the
linux
foundation,
antitrust
policy,
and
you
can
also
review
this
antitrust
policy
both
on
our
bikie
and
on
our
website.
This
session
is
being
recorded,
live
and
it
will
be
available
in
our
hyperledger
library,
along
with
a
slide.
So
you
are
very
welcome
to
download
it
later
and
review
the
slides
and
to
get
you
know
like
if
you
want
to
refresh
the
information
share
today.
You
are
very
welcome
to
do
it.
A
So
we
always
encourage
for
these
webinars
to
be
as
interactive
as

The
better
experience
will
will
there
be
for
everybody
and
more.
A
You
are
very
welcome
to
post
it
on
our
discord
channel,
which
we
will
share
in
a
chat
in
just
a
moment,
so
again
feel
free
to
talk
to
communicate
and
ask
questions
to
our
panelists,
and
we
will
be
happy
to
answer
them
now
without
further
ado,
I'm
happy
to
introduce
our
panelists,
which
is
iana
cordra,
the
head
of
product
management
at
intellectu
and
vladislav
koppak
rodorowski,
which
is
a
technicality
at
the
intellect
eu.
You
and
we'll
be
doing
the
portion
of
the
q
and
a
sessions
later
so
without
further
ado.
B
Thank
you
very
much,
thomas
and
good
morning,
good
afternoon.
Everyone
thank
you
for
joining
us
today,
so
I'm
jana
leading
products.
I
didn't
like
to
you.
I'm
super
inspired
by
profiles.
I
looked
through
some
registering
profiles
yesterday
before
the
meeting,
so
I
strongly
encourage
you
to
interrupt
me
whenever
you
think
you
have
questions
or
comments
to
share.
B
B
I
will
speak
about
mistakes
to
avoid
by
program
and
product
managers
before
starting
hyperliterary
fabric
projects
and
during
the
second
part,
our
technical
lead.
Vlad
kapayagarotsky
will
hold
a
q
a
session
to
answer
your
technical
questions.
So
if
you
have
technical
questions,
please
prepare
my
part
of
presentation
will
take
probably
up
to
25
minutes.
So
after
that
you
will
be
able
to
participate
in
a
real
conversation.
B
I
will
add
a
little
bit
to
the
introduction
of
lot.
So
blood
is
not
only
the
technical
elite
of
our
flagship
product,
the
catalyst
blockchain
platform,
but
also,
several
years
ago,
he
launched
an
r
d
unit
within
intellect
eu,
with
an
idea
to
create
a
management
solution
for
hyperletter
fabric,
to
make
it
easier
to
manage
scale
and
deploy
fabric,
and
after
several
years
it's
a
product,
it's
a
large
team
and
our
clients
not
only
using
the
product
for
their
pocs,
but
actually
for
running
projects
in
production.
B
B
B
We
by
the
way,
was
one
of
the
organizations
first
of
the
organization
that
integrated
in
the
into
the
ripple
mainnet
and
in
2016
we
became
one
of
the
founding
members
of
hyperledger
organization
under
linux
foundation.
This
is
a
vibrant
community
and
we
had
many
opportunities
being
part
of
it.
So
we
do
appreciate
it
so,
based
on
our
extensive
experience
of
delivering
many
hype,
many
hyper
ledger
and
other
blockchain
based
projects
for
clients.
B
B
It
helps
you
to
deploy
your
networks,
manage
your
network
scale,
your
network
through
user
interface,
and
if
you
prefer
to
use
api,
you
can
use
api.
We
also
built
enterprise,
great
features
and
the
next
slide.
Please,
enterprise
features
on
top
of
the
open
source
and
by
enterprise
features.
I
mean
features
related
to
the
security
to
the
reliability
and
monitoring
and
many
others.
On
top
of
that,
with
catalyst
blockchain
platform,
you
can
run
your
hyperledger
fabric
networks
using
any
infrastructure
of
your
choice.
It's
absolutely
cloud
agnostic.
B
B
Today,
banking
world
invented
world
of
programmable
payments
are
limited
to
credit
transfer
and
direct
debits.
Basically,
so
our
clients
are
looking
into
how
to
add
value
to
through
the
blockchain
technology,
to
bring
increasing
functionalities
for
programmable
programmable
money,
kyc
platform
for
banks.
So,
as
you
probably
know
now,
your
customer
procedures
are
very
time
consuming
labor-heavy
and
expensive
and
the
requirements,
anti-money
laundering
and
requirements
are
becoming
increasingly
strict.
B
I
just
don't
want
to
take
too
much
time
just
for
you
to
understand
what
kind
of
projects
we've
been
working
with
and
where
are
we
taking
our
ideas
about
how
to
optimize
the
usage
of
hyperledger
fabric
are
coming
from.
So
let's
start
from
the
first
mistake
to
avoid,
and
please
do
not
think
that
it's
very
obvious
in
high
level.
B
So
what
we
usually
do,
and
actually
our
client
that
do
not
do
this
from
the
beginning.
They
eventually
do
this
with
us
a
little
bit
later.
We
provide
a
session
on
hyperledger
fabric,
a
key
concept
as
well
as
on
how
to
use
catalyst,
blockchain
platform
and
also
we
do
a
workshop
to
discuss
and
understand
what
would
be
the
optimal
setup
and
deployment
for
the
client-specific
use
case.
B
The
the
same
applies
to
the
partners
of
our
clients,
because
usually
high-quality
fabric
consortiums
are
led
by
certain
organization
and
those
organization
leaders.
They
hold
all
the
hyperledger
knowledge
within
the
consortium
and
they
need
to
have
mechanisms
to
share
this
knowledge
with
other
participants.
B
This
is
a
very
popular
topic
to
discuss.
You
can
have
fun
reading
dozens
of
articles
online
on
blockchain
performances.
If
clients
are
on
the
early
stage,
they
sometimes
consider
like
using
blockchain
overall.
So
they
might
compare
it
to
the
discrete
distributed
databases
and,
of
course,
later
show
better
performance
than
the
first.
But,
of
course,
comparison
is
a
result
of
a
certain
misconception.
B
So,
first
question
that
we
ask
our
clients
what
kind
of
performance
parameters
are
important
for
you?
Is
it
latency?
Is
it
throughput?
Is
it
scalability?
Some
clients
are
concentrating
on
the
throughput.
However,
we
have
seen
that
even
for
most,
even
for
most
demanding
use
cases
500
or
up
to
1000
transactions
per
second
is
enough
in
finance
clients,
quite
oftenly
prioritize
latency
over
throughput,
so
we
know
that
hyperledger
fabric
actually
outperforms
many
other
blockchain
protocols
in
both
those
parameters
and
especially
in
their
combination.
B
So
in
addition
using
a
proper
design
high
protein
fabric,
when
you
scale
and
you
your
network,
you
can
achieve
minimal
implications
on
other
performance
parameters.
However,
it's
really
important
to
find
balance
between
understanding
how
you
want
to
improve
your
throughput
and
how
it
correlates
with
your
compute
networking
and
storage.
B
So
if
you
want
to
increase
the
number
of
transactions
per
second,
you
also
need
to
understand
that
you
will
need
to
have
faster
execution
of
transaction
processing.
In
terms
of
networking,
we
will
need
faster
peer
to
peer
networking
and
in
terms
of
storage.
Of
course,
you
will
need
to
have
speed
up
access
to
the
storage
and
your
storage
will
grow
faster.
So,
whatever
we
want
to
achieve
in
terms
of
performance,
we
should
always
understand
which
performance
parameters
are
the
highest
priority
for
you.
B
The
third
mistake
to
avoid
is
the
my
favorite
one,
because
I
hear
these
questions
basically
from
every
potential
client,
so
mistake
is
believing
that
interoperability
is
actually
possible.
So
at
the
moment,
interoperability
between
different
blockchain
particles
is
not
possible.
There
are
different,
researches
and
different
products
that
are
trying
to
achieve
certain
level
of
data
exchange
between
blockchain
platforms.
However,
when
we
speak
about
interoperability
between
different
platforms
built
on
different
protocols,
we
expect
to
see
shared
data.
B
We
expect
to
see
similar
seamless
transactions
across
networks,
and
we
expect
to
have
possibility
to
share
and
exchange
tokens
across
those
networks,
but
different
protocols
speak
different
languages
and
smart
contracts.
Usage
is
different
on
various
platforms.
Moreover,
there
are
different
consensus
mechanisms,
data
structures,
data
processes
is
all
different
and
each
platform
is
still
tailored
for
a
specific
set
of
use
cases
with
specific
features.
So
all
of
this
prevents
transferring
data
and
even
more
sharing
or
exchanging
between
or
across
this
networks,.
B
However,
clients
are
trying
to
be
visionary
and
think,
like
long
term
like
we
all
expect
at
some
point
for
different,
like
blockchains,
to
be
interoperable
and
and
live
in
the
interoperable
world,
rather
than
separate
small
networks
here
and
there,
so
for
it
for
clients
that
are
really
looking
long-term
and
thinking
about
how
they're
going
to
maybe
migrate
to
some
other
like
updated,
blockchain
products
calls,
etc.
We
do
provide
an
opportunity
to
use
demo
on
fabric
so
within
catalyst,
blockchain
platform.
B
We
support
digital
asset
modeling
language,
the
language
that
was
specifically
designed
designed
for
smart
contracts
and
with
the
demo.
You
can
build
your
smart
contract
once
and
you
can
use
it
anywhere,
basically
on
any
blockchain
protocol
or
even
proprietary
database
and
demo
apps
are
atomically
interconnected,
so
within
catalyst,
blockchain
platform.
B
There
are
two
options,
so
either
organization
has
technical
capacity
to
do
that,
but
does
want
to
create
the
network
of
its
own
or
doesn't
have
technical
capacity
to
join
the
network,
although
is
willing
to
join
the
network
and
participate
in
the
in
the
use
case,
and
this
is
not
a
trivial
task
to
grow
your
network,
so
we
were
thinking
about.
How
can
we
help
our
clients
to
provide
their
clients
with
easier
options
for
onboarding?
B
So
this
is
something
that
we
suggest
our
clients
to
do
to
think
about
how
they
are
going
to
grow
their
networks
and
what
they
are
going
to
offer
their
clients.
Understanding
that
technical
capacity
is
a
limitation
for
sure
for
growing
the
blockchain
network,
and
the
last
mistake
that
I
wanted
to
discuss
is
relying
on
off
chain
covering
it.
So
anyone
who
actually
did
run
hyperledger
fabric
projects
know
how
difficult
it
is
to
execute
of
chain
car
or
nets,
and
to
avoid
this,
we
need
to
have
the
voting
system.
B
So
I
will
quickly
share
how
we
do
this
with
an
intellect
within
get
us
blockchain
platform.
So,
for
example,
you
want
to
on
board
an
organization
to
a
channel.
So,
in
order
to
do
this
for
the
world
to
through
the
catalyst
vote
and
system,
you
simply
go
to
the
channel
tab.
You
click
add
organization,
you
specify
you
select
an
organization
from
the
list
of
your
partnering
organization.
You
specify
the
ordering
note
yeah
the
the
previous
slide,
so
you
specify
parameter
the
ordinal
node
from
the
system.
B
Instead,
the
proposal
was
created
so
after
this
and
on
the
next
slide,
you
will
see
this
through
the
eyes
of
other
organizations,
so
in
other
organizations
that
participate
on
the
channel,
they
will
need
to
go
to
the
channel
sections
click
on
proposals
section
and
then
they
will
see
that
their
pending
proposal
to
add
an
organization
to
a
channel
that
they
are
about
to
approve
or
not
approve.
So
before
all
organizations,
depending
on
your
policy
will
approve
adding
this
organization
to
a
channel.
B
A
Thank
you
very
much
jana.
That
was
a
very
interesting
presentation
and
very
relevant
topics,
and
you
know
to
discussion
what
to
avoid
when
deploying
the
high
pleasure
fabric.
Now
we
do
have
some
questions
and
I
do
see
that
machine
has
raised
his
hand.
So
just
a
second
I
will
unmute
you
talk
so
machine.
Please
feel
free
to
unmute
yourself
and
ask
the
question
to
vlad.
C
Thanks
vlad,
it
was
a
very
good
session
we
had
thanks
for
that.
I
just
got
a
quick
question
where
in
the
concern,
or
rather
an
observation
which
was
shared
regarding
adoption
of
hyperledger
fabric,
although
if
one
organization
adopt
it,
it
becomes
very
vital
and
important
for
other
organization
also
to
chip
in.
So
in
that
mean,
do
we
have
any
technical
certification
that
we
can
look
out
for?
C
D
Can
you
clarify
your
question?
I
mean
like
you're
you're,
saying
that
at
the
beginning
you
had
a
single
organization
right
and
then
you
were
saying
that
there
are
others
that
are
willing
to
join
through
some
certification
process.
What
do
you
mean
with
certification
process
because
I
didn't
understand,
I'm
sorry.
C
Yeah,
so
if
we
have
hyper
ledger
in
our
organization
and
if
we
are
inviting
the
next
organization
or
our
partners
to
join
in
and
since
they
don't
have
capabilities,
the
technical
capabilities,
can
we
then
not
recommend
them
to
go
through
a
technical
course
on
hyperledger,
which
will
enable
them
to
then
feel
comfortable
and
then
join
in?
And
likewise
the
chain
would
grow.
D
D
Basically,
it's
a
bunch
of
certificates,
but
all
of
the
structure
is
hosted
by
someone
else.
So
our
ordering
service
is
hosted
by
someone
else.
Peers
are
can
be
hosted
by
someone
else,
so
that
organization
that
is
joining
and
does
not
have
capability
can
join
a
network
just
with
an
msp
id,
and
they
can
also
connect
their
applications
and
involve
transactions
on
behalf
of
that
msp
id.
D
But
somebody
somebody
else
needs
to
be
needs
to
host
infrastructure
for
for
others,
I
would
say
so
yeah
it's
possible
and
it's
a
it's
a
popular
use
case.
I
would
say,
because
we
I
hear
a
lot,
that
there
are
some
companies
that
have
huge
teams
of
devopses.
They
can
host
anything,
but
also
there
are
other
small
ones
that
basically
don't
have
enough
resources
and
they
are
willing
to
join
and
they
are
they're
believing
that
in
future
they
will
have
some
resources,
but
they
want
to
join
now.
D
So
what
to
do?
What
we
propose
is
to
either
use
a
ready
to
ship
like
out
of
the
box
solution
like
kbp
or
any
other
on
the
cloud
that
the
first
option.
The
second
option
is
to
ask
somebody
to
host
notes
for
you
important
that
you
are
not
obliged
to
host
orders,
because
origin
service
should
be
hosted
only
by
trusted
partners,
and
basically
you
don't
even
need
peers.
If
you
have
like
different
msp
id,
you
can
invoke
your
transaction
using
pierce
of
somebody
else.
D
Of
course
it
depends
on
endorsement
policy,
but
for
most
use
cases
it's
fine.
So
I
think
there
are
possibilities.
Yes,
but
you
need
to
trade
like
you
need
to
do
trade-offs
right,
so
you
don't
have
enough
resources,
delegate
it
to
somebody
else
and
wait
until
you
have
enough,
but
the
best
practice
again
is
to
transfer
transfer
hypogeofabric
knowledge
and
allow
all
organizations
to
close
their
host.
Their
nodes
and
to
be
a
consortium
fully
decentralized
only
in
that
way,
it's
a
true
setup
of
hyperlogic
fabric.
From
my
perspective,
of
course,.
C
D
A
D
Yeah,
so
it's
a
very
often
asked
question
about
disaster
recovery
mechanism
and
when
we
are
talking
about
disaster
recovery
of
hyperledger
fabric,
we
need
to
understand
and
we
need
to
know
that
it's
a
distributed
system.
So
I
always
tell
people
instead
of
building
like
bulletproof
disaster
recovery
mechanism,
make
sure
you
have
a
good
consortium,
a
good
good
enough
conversion
that
you
have
enough
ordering
notes
that
are
shared
among
trusted
partners
and
if
half
of
those
partners
where
I
go
down,
you
still
have
forum.
D
So
that's
the
first
important
note
always
make
sure
you
have
a
good
consortium
and
that
is
deployed
across
multiple
clouds:
multiple
infrastructures.
That's
the
first
thing.
Second
thing:
just
recovery:
it's
can
go
through
a
backup
and
restoration
process,
so
apology
fabric
has
possibility
to
back
up
the
note
and
store
it
from
you
know
from
a
backup.
D
D
That's
the
only
two
options
I
would
say
just
backup
and
restore
from
yeah
backup
and
restore
not
from
a
backup
and
having
good
enough
consortium,
making
sure
that
at
any
point
of
time,
if
one
organization
disconnects
you
still
have
a
quorum
of
ordering
service,
that's
the
most
important
thing.
You
don't
need
to
care
about
peers.
I
would
say
you
don't
need
to
care
about
cas.
The
most
important
part
of
hyperledger
fabric
is
ordinary
service,
and
as
long
as
ordering
service
leaves,
you
can
continue
joining
new
peers
and
executing
transactions.
D
So,
as
a
user,
you
have
a
single
msp
id
that
can
be
shared
across
two
clusters
and
in
each
cluster.
You
would
have
like
a
few
peers
if
you
are
hosting
orders
or
sorry
a
few
orders,
if
you
are
hosting
them
and
also
a
few
peers
like
two
on
region,
one
and
two
on
region.
Two
and
at
any
point
of
at
any
point
of
time.
If
your
one
region
fails,
you
can
easily
switch
router
to
the
second
cluster
that
is
up
and
running
and
continue
accepting
transactions,
invoking
them
and
so
on.
D
So
to
summarize,
first
of
all
good
enough
quorum.
Second
of
all,
having
backup
backup
and
functionality,
you
know
so
you'll
be
able
to
back
up
a
note
and
restore
it,
and
the
third
is
a
possibility
to
deploy
across
multiple
regions,
though
the
last
one
is
expensive.
Usually,
and
not
all
customers
decide
to
go
with
so
that
it
really
depends
on.
It
really
depends
on
your
resources
and
requirements.
I
would
say
and
yeah
that's
it.
Thank
you.
A
D
Of
banks,
for
example,
in
a
kyc
use
case,
it
depends
on
your
consortium,
but
usually,
of
course,
it's
a
one
root
ca
that
is,
that
is
public.
Usually,
then,
there
is
a
private
ca
of
company
like
of
a
of
a
consortium
company,
for
example,
and
then
we,
I
would
say
suggest
to
use
on
the
third
level,
is
hyperlogic
fabric
c,
as
an
intermediate
of
course,
so
you
have
three
cas
the
first
one,
which
is
public.
D
The
second
one
are
its
private
of
that
belongs
to
a
company
that
is
holding
consortium
and
the
third
one
is
the
lowest
level
is
hyperledger
fabric
ca,
because
it's
the
most
easier
way
to
manage
hyperledger
fabric
identities
with
hyperledger
fabric
ca.
I
would
say,
of
course,
you're
not
obliged
to
use
hypology
fabric
ca.
If
you
don't
like,
I
heard
a
lot
from
security
enterprise
consultants
that
they
don't
like
it
for
various
reasons,
mostly
for
security,
and
we
have
a
successful
cases.
D
D
So
it's
a
very
like,
I
would
say
it's
it's
a
secure
way
to
launch
your
own
ca
on
your
own
infrastructure
and
also
hyperledger
fabric.
You
can
integrate
it
with
hashicorp
wall
to
store
all
the
identities
and
there
is
even
possibility
if
you
know
what
to
do
to
store
to
to
use
transit
engine
of
hashicorp
wall
and
to
store
all
private
keys
only
in
hashicorp
gold,
so
they
never
leave
the
storage.
D
D
So
yes,
regarding
that,
when
you're
doing
a
backup,
you're,
basically
packing
all
the
data,
like
oh
hold
your
ledger
into
archive,
and
then
it's
really
saves
you
a
lot
of
time.
If
you
have
a
huge
ledger,
instead
of
starting
appear
from
scratch
from
block
number
one.
So
yes,
that's
definitely
a
case
for
disaster
recovery
because
we
have
netflix.
We
have
networks
with
like
a
few
million
blocks
and
starting
new
year
from
from
block
number
one
could
take.
D
I
would
say
day:
it
depends,
of
course,
on
your
performance,
but
yes,
it's!
It
increases
your
speed.
A
lot
also
take
a
look
at
snapshot.
Functionality
of
appears
there
is
functionality
that
allows
you
to
start
appear
from
a
snapshot.
You
won't
be
able
to
query
previous
blocks,
but
you
will
have
the
needed
world
state.
A
D
D
Can
you
remove
appear
from
a
transaction
flow
if
I'm
not
mistaken,
just
go
directly
like
form
a
proposal,
go
directly
to
order
and
commit
it
to
tell
the
truth.
I
have
never
done
it,
but
I
think
it's
possible
if
you
have
access
to
peers
to
pierce
keys
to
peer
scripted
materials,
because
proposals
needs
to
be
signed.
It
needs
to
be
signed
on
behalf
of
them,
if
I'm
not
mistaken,
but
in
general,
if
you
can
form
a
proposal
and
send
it
to
order
and
order
accepts
it.
D
Yes,
why
not,
but
no
no,
no,
I'm
sorry!
So
there's
a
lot
going
on,
and
especially
when
you
have
a
private
collection,
for
example.
This
case
isn't
possible
because
private
collection
is
stored
on
appear
during
transaction
flow
and
you
won't
be
able
to.
You
won't,
be
able
to
modify
and
or
send
your
private
collection
information
to
order,
because
order
does
not
know
anything
about
private
data.
D
So
I
think
it
really
depends
on
the
use
case,
somehow
it's
possible
to
mischief
it.
But
to
tell
the
truth,
I
never
tried
you
can
follow
up
me
only
me
on
the
email
and,
if
you're
really
interested
in
in
this
question,
you
can
talk
about
it.
I
think
also
I'm
in
a
discord
chat,
so
we
can
talk
there.
It's
interesting
use
case
and
I've
never
thought
about
it.
B
A
D
Oh,
if
you're
asking,
if
you're
talking
about
kbp,
so
it's
a
half
manual
process,
I
would
say,
because
we
are
delivering
an
application
that
is
running
on
kubernetes,
so
our
application
does
does
not
have
control
over
kubernetes,
and
in
order
to
do
a
backup,
you
would
need
to
backup
a
persistent
volume
claim.
You
would
need
to
make
a
snapshot
of
this
of
a
volume.
D
D
But
since
our
application
is
now
spaced
and
it
can
download
data
from
volume,
we
are
limited
to
some
processes
and
those
needs
to
be
handled
manually
like
half
manually.
It's
it's
definitely
much
simpler
to
do
with
nbp,
rather
than
build
it
yourself,
but
inter
interaction
of
a
blockchain
operator
is
needed.
D
Because
again,
applications
in
kubernetes,
they
don't
have
control
over
volumes,
and
you
would
need
to
transfer
that
volume.
Somehow.
The
only
thing
that
application
can
do
with
integration
with
operator,
for
example,
is
to
shadow
a
snapshot,
a
regular
snapshot
of
your
node.
That's
what
application
can
do,
but
the
rest
should
be
triggered
by
a
user.
A
D
D
So
it's
called:
we
have
signatures,
no,
no,
no
signature.
What
what
was
the
word
yeah?
We
have
sign-in
identities
for
local
msp
ids.
So,
for
example,
let's
take
a
look
at
here
here
has
sign
in
identity
and
tls
identity.
What
happens
if
we
renew
them?
Basically,
nothing
if
you
make
sure
that
renewed
identity
is
belongs
to
the
same
sca.
D
It's
fine
and
you
don't
need
to
modify
your
ledger
because
assign
an
identity
of
a
peer
and
tls
identity
of
appear
are
not
stored
on
the
ledger,
so
you
can
renew
them
without
any
doubt,
the
second
we
have
order
and
with
order
it's
a
bit
different
story,
so
signing
identity
of
an
order
can
be
rotated
again
easily
and
you
don't
need
to
touch
ledger.
So
what
you
need
to
do
is
to
regenerate
a
certificate
using
whatever
ca.
You
have
and
restart
your
order.
That's
it,
but
with
stella's
identity
is
different
story.
D
You
run
channel,
update
transaction
once
it
once
it
was
accepted
by
orders,
you
put
it
inside
of
order
and
restart
node
after
some
time,
like
order
is
recognized,
is
a
new
certificate
and
it's
up
and
running
from
our
site
from
side
of
kvp.
We
are
automating
this
process.
The
only
thing
you
would
need
to
do
is
basically
two
or
three
steps.
D
First
of
all,
you
would
need
to
go
to
a
ca
and
generate
new
certificate
and
place.
The
old
one
into
certificate.
Revocation
list
then
go
to
a
channel
by
channel
starting
from
a
system,
one.
If
you
have
and
channel
by
channel
you
would
need
to
rotate
certificate.
Of
course
it
depends
on
your
policy
on
the
channel.
So
if
your
policy
on
the
channel
does
not
allow
you
to
does
not
allow
you
to
endorse
transaction
only
by
yourself,
meaning
you
have
majority
and
a
number
of
organization
is
bigger
than
two.
D
D
So
with
our
kvp
certificate
rotation
process
takes
you
like
at
most
20
clicks,
and
you
would
need
to
visit
three
modules
and
that's
the
process
about
a
misperitation.
It's
much
simpler
than
rotation
of
consenters,
because
in
order
to
rotate
the
msp
certificate,
you
would
need
you
don't
need
to
collect
any
signatures.
Msp
belongs
to
you
and
you
are
the
only
one
who
is
responsible
for
it.
So
you
don't
need
to.
A
A
B
B
That
means
that
we
don't
build
products
for
other
organizations
and
the
use
cases
I
I
mentioned.
Sometimes
our
colleagues
participate
in
development
of
the
projects
for
clients,
but
mainly
I
was
talking
about
client
that
purchased
catalyst
blockchain
platform
to
build
projects
on
top
of
it.
So
we
did
not
build
their
solutions.
B
D
Answering
keyboards
question:
it's
about
quantum
computing.
It's
I
heard
first
time
I
heard
this
question.
It
was
like
2015
and
you
were
learning
doubles
and
usual
assets
are
not
mistaken
and
everyone
was
asking
like
about
quantum
comp
computing.
So
what
I
can
tell
you?
Yes,
it's
possible,
but
we
are
really
far
behind
of
this
being
used
by
enterprise
companies
and
really
by
quantum
computing
adult
adoption.
D
D
A
Thank
you
very
much
vlad.
We
are
almost
at
the
top
of
the
hour,
but
we
also
have
a
question
from
youtube
so
and
it
was
posted
in
a
chat.
So
are
you
saying
there
could
be
single
notes,
potentially
in
the
forms
of
devs,
with
hyper
ledger
expertise
that
can
be
used
to
onboard
and
maintain
large
number
of
organization
onboardings,
as
by
ethan
miller,.
D
Yes,
it's
possible
and
that's
one
of
use.
Cases
we
were
considering
is
our
client,
because
a
client
wanted
to
host
all
the
infrastructure,
but
clients
of
our
client
were
very
small
and
they
couldn't
just
host
anything.
So
we
were
issuing.
We
were
issuing
msp
like
a
unique
msps
with
cas
and
adding
those
msps
on
the
channel
and
invoking
transaction
transactions
on
behalf
of
them.
D
The
only
problem
would
be
is
endorsing
endorsing
policy,
but
it
really
depends
on
your
use
case.
A
lot
of
customers
use
hyperledger
fabric
with
endorsement
policy
any,
and
it
means
they
don't
really
care
about
data,
not
just
consistency,
but
data
security.
They
just
use
mostly
hyperloop
fabric
for
distribution.
