Description
A virtual meetup hosted by Hyperledger Denver about Hyperledger Fabric for System Administrators vs Developers. When designing and building an enterprise blockchain application on Hyperledger, it is very important to distinguish between the system administration tasks and the development ones as they may entail two different career tracks and job requirements. The said distinction has direct effects on the project staffing, project management and timely delivery.
To that end, in this short webinar, we will review and discuss tasks that are common among Hyperledger Fabric system admins versus developers as well as briefly reviewing available Hyperledger certifications for each career track.

A
Yeah,
no,
no
problem.
Everything
looks
great
from
my
perspective,
jim,
so
I
think
when
we're
ready
to
go,
you
can
just
leave
that
slide
deck
up
there
and
then,
or
maybe
pull
it
down,
we'll
just
kind
of
do
the
exact
thing.
Can
you
stop
sharing
your
perfect
then,
when
we
hit
the
top
of
the
hour
I'll,
do
the
introduction
for
you
and
then
also
we're
going
to
have
bobby
from
the
hyperledger
technical
steering
committee
and
learning
materials
working
group
also
do
a
presentation
and
she's
on
the
meet
up
right
now
as
well.
A
How's
that
you're
awesome
perfect
bobby
great
to
see
you
thanks
for
joining
us
and
let's
go
ahead
and
let's
see,
if
I
can
okay
yeah,
I
can
easily
make
it
where
jim
is
just
the
only
presenter.
So
I'll
invite
you
back
when
we're
ready
to
go
here
bobby
perfect,
but
maybe
what
I'll
do
is
as
the
intro.
Let's
all
three
stay
on
here
and
then
I
can
go
through
and
introduce
you
as
well
bobby.
A
The
live
chat
is
for
the
attendees,
so
I'll
just
be.
You
know
the
host
and
moderator
here:
okay
and
then
jim
you're
gonna
start
off
and
do
your
roughly
30
minute
presentation,
then
we're
going
to
take
a
few
minutes
of
q.
A
then
bobby,
I'm
going
to
turn
it
over
to
you
and
talk
about
your
great
work
with
the
technical
steering
committee
and
then
we're
going
to
go
ahead
and
break
out
of
the
main
room
presentation
and
then
go
into
what
I
call
the
you
know:
meet
up.
B
B
B
A
A
A
A
So
jim's
going
to
give
us
a
great
presentation.
And
then
I
also
have
the
pleasure
of
having
bobby
mascara
from
the
hyperledger
technical
steering
committee
joining
us
today,
which
I'm
very
pleased
about
and
she's.
Also
the
chairperson
of
the
hyperledger
learning
materials
working
group
and
she
has
done
a
great
job
with
really
updating
the
hyperledger
website.
With
all
these
great
learning
materials.
B
B
Am
I
projecting
everything,
looks
perfect?
Okay,
fantastic
great
well
again,
welcome
everyone!
My
name
is
jim
sullivan
and
let
me
get
my
here
and
we're
going
to
talk
about
hyper
fabric
for
system
administrators
versus
developers
and
we're
also
going
to
talk
about
some
of
the
the
attributes
of
a
system
administrator,
a
hyperledger
fabric
system
administrator
job.
B
So
we
can
see
here
hyperledger
fabric,
certifications
and
career
choices,
so
think
about
it.
Now
you
know
how
much
do
you
know
about
hyperledger
john
already
covered
this,
so
our
outline
here
is
going
to
be
hyperledger.
Fabric
highlights
and
hf
is
going
to
be
hyperledger
fabric,
the
components
in
the
architecture,
hyperledger
system,
administration
and
hyper
ledger
application
development.
B
B
I
still
know
a
lot
of
the
hyperledger
team
down
at
ibm,
so
I
am
we're
keeping
in
touch
with
them
on
a
regular
basis,
so
some
highlights
about
hyperledger,
so
the
hyperledger
in
in
and
of
itself,
is
more
of
a
distributed.
Ledger
technology,
not
exactly
the
same
as
a
blockchain
like
bitcoin.
I
can
say
it
like
this.
All
all
blockchains
are
distributed
ledgers,
but
not
all
distributed.
Ledgers
have
that
it
have
that
blockchain
architecture
like
we
think
of
bitcoin
or
even
ethereum.
B
Hyperledger,
though,
is
a
permissioned
distributed,
ledger
technology
a
little
bit
different
from
a
public
one
where
we,
where
you
see
all
the
cryptocurrency
traded,
it's
highly
modular.
It
has
plugable
consensus
a
lot
of
times.
We
hear
about
these
consensus,
algorithms,
like
proof
of
work.
Well,
when
you
get
down
to
permission
blockchains,
it's
the
consensus
of
the
transactors.
B
That
matter,
you
know
we
don't
need
somebody
out
there
to
list
all
the
create
a
new
block
list,
all
the
transactions
in
there
and
then
everybody
votes
on
which
block
has
the
has
the
correct
transactions?
It's
it's
not
like
that
at
all.
There's
an
open
smart
contract
model,
so
we're
gonna
we'll
talk
about
some
smart
contract.
I
imagine
everybody
knows
what
those
are,
but
those
are
applications
that
execute
transactions
on
hyperledger,
low,
late,
low
latency
and
finality
and
confirmation
and
flexible
approach
to
data
privacy.
B
So
smart
contracts
can
be
written
in
multiple
languages,
and
this
is
true
for
a
lot
of
blockchain,
so
we
have
go
which
is
very
popular,
obviously
java,
javascript
or
also
have
been
around
a
long
time.
There
is
support
for
ethereum
for
the
ethereum
virtual
machine
through
solidity,
and
it's
designed
for
continuous
operations,
including
rolling
upgrades,
asymmetric
support
version,
support,
governance
and
versioning
of
smart
contracts.
B
B
So,
like
I
was
introducing
hyper
ledger,
is
designed
to
have
specialty
nodes
and
corda
also
is
built.
That
way.
Corta
is,
I
guess
you
could
say,
a
competitor
somewhat
of
hyper
ledger
and
fundamental
unit
of
the
hyperledger
network.
No
question
about
it.
The
peers
maintain
the
ledger
and
the
smart
contracts,
so
the
ledger
is
not
really
kept
it.
It's
it's
managed,
but
the
the
ledger
is
is
managed
slightly
differently
than
what
we
would
think.
A
typical
blockchain
ledger
would
be
managed,
and
here
are
the
peer
types
again.
B
An
orderer
is
another
node,
that's
part
of
hyperledger
and
it's
the
mechanism
by
which
the
applications
and
the
peers
interact
with
one
another
and
the
the
orderers
are
there
to
ensure
that
every
peer's
ledger
is
kept
consistent
with
each
other,
because,
obviously
we
we
need
that
agreement.
So
these
are
specialty
nodes
again
called
orders
their
order.
It
says
your
order
types.
These
are
messaging
services.
You
might
recognize
these
kafta
solo.
B
These
are
deprecated,
as
a
version
too
raft
is
what
is
recommended.
Also,
I
believe
ibm's
mq
messaging
has
now
been
added
to
version
two.
I
believe
that
is
the
case.
Given
what
I
know
about
ibm
and
ibm's
are
our
tools
are
great
products,
but
they
sometimes
are
extra
extra
complicated
raft
might
be
the
really
the
recommended
way.
I
certainly
agree
with
this,
so
the
the
orderer
atomically
broadcasts
the
committing
transactions
so
to
all
the
peers,
and
they
it
receives
the
same
block
transactions
from
the
same
order.
B
So
the
order
of
service
orders
transactions
uses
a
first-come,
first-served
basis
and
the
transaction
is
ordered
after
the
transactions
are
ordered.
The
records
are
committed
and
grouped
and
assigned
as
part
of
a
block
for
that
communication
channel.
So
the
ordering
service
is,
will
manage
all
the
transactions
and
make
sure
that
the
the
transaction
records
are
committed
to
their
assigned
groups.
B
So
again,
raft
versus
kafka.
Kafka
is
quite
popular
if,
if
you've
ever
used,
uber
you've
used
kafka
from
behind
the
scenes,
but
your
raft
is
supported,
natively
and
which
means
that
users
are
required
to
keep
their
requisite
images
and
learn
how
to
use
copter
and
zookeeper
on
their
own.
So
you
can
use
kafka
and
or
I'm
sorry,
you
can
use
mq
as
well.
So
please
look
into
that.
If
you're
more
of
an
ibm
person.
B
B
Again,
it's
custom,
so
the
certificate
authority
is
custom
and
the
the
roots
are
the
root
certificate
authority
needs
of
fabric
is
inherently
not
capable
of
providing
ssl
certificates.
So
you
know
that
https
that
you
see
so
it's
it's
not
provided
by
hyperledger
fabric,
so
there's
no
general
automatic
use
of
it
within
browsers.
B
B
So
the
ledger
still
stores
the
important
parts
of
the
business
transactions.
So
the
ledger
consists
of
of
two
parts:
the
world
state
and
the
blockchain,
which
is
nothing
but
a
transaction
log.
So
the
world
state
is,
is
the
state
of
that
ledger
and,
interestingly
enough,
we
always
hear.
Oh
a
database,
a
relational
database
or
a
database
and
a
blockchain
they're,
not
the
same
thing.
B
You
either
use
one
or
the
other,
but
most
likely,
if
you
ever
host
or
familiar
with
any
kind
of
distributed,
ledger
technology
or
blockchain
node,
most
likely
somewhere
in
there
in
the
infrastructure
of
the
node.
There
is
a
database
and
that's
the
same
for
hyperledger.
These
are
what
we
call
nosql
databases.
So
a
leveldb
is
the
default.
You
have
that
to
manage
the
world
state
of
the
ledger
and
you
also
have
couchdb.
B
So
both
of
these
are
are
quite
popular
and
the
ledger
is
absolutely
tamper
resistant
because
it
is
hashed
and
it
records
the
state
of
all
transactions
and
they
are
a
result
of
the
the
chain
code
invocation.
So
as
the
chain
code
executes,
there
are
updates
to
the
ledger
and
each
transaction
does
result
in
those
key
pair
values
and
they're
committed
to
the
ledger
as
creates
or
updates
or
deletes,
and
that
is
going
to
be
committed
to
the
to
the
world
state
like
that.
B
So
some
of
the
features
are
the
query
and
update
using
key
based
lookups,
so
we
can
enter
keys.
Looking
for
certain
values,
we
have
read
only
queries
that
using
the
rich
query,
language
associated
with
couch
there's
also
read-only
history.
So
we
can
query
history
for
certain
keys
to
enable
data
just
for
reporting
and
enable
certain
data
scenarios.
B
Peers
then
validate
the
transactions
against
the
endorsement
policies
and
they
also
enforce
the
policies
so
prior
to
appending
a
block.
A
version
check
is
performed
to
ensure
that
the
states
of
the
assets
or
the
transactions
that
were
read
have
not
changed
since
chain
code
execution
time.
So
this
is
interesting.
This
comes
up
a
lot
in
a
lot
of
blockchain
training.
B
These
transactions
sometimes
get
queued
up.
So
if
we
have
to,
there
could
be
times
where
the
actual
state
of
the
ledger
changes,
because
a
different,
a
different
contract
or
different
chain
code
has
has
run,
and
there
is
immutability
once
a
transaction
has
been
validated
and
committed.
So
immutability
is
performed
through
hashing
of
the
data.
B
And
the
channels
ledger
contains
a
configuration
block,
defining
policies
and
access
control
and
other
pertinent
information,
and
there
is
member
there's
a
membership
service
provider.
Every
channel
contains
the
msp
instances
allowing
for
crypto
materials
to
be
delivered
from
the
certificate
authorities.
We
can
see
here.
Hyperledger,
as
the
name
implies,
supports
multiple
ledgers,
so
we
can
see
here
our
peer
and
we
can
have
multiple
ledgers.
These
are
called
channels,
so
a
channel
is
a
ledger
or
a
mechanism
where
certain
interested
parties
can
transact
on
the
blockchain
network
communicate
collaborate.
B
B
B
So
some
channel
characteristics
again
the
election
of
a
leading
peer
for
each
member
on
a
channel
determines
which
peer
communicates
with
the
ordering
service.
On
behalf
of
that
member,
so
no
ledger
data
can
pass
from
one
channel
to
another,
so
they
are
completely
separate,
separate
ledgers.
The
separation
of
ledger
by
channel
is
defined
and
implemented
by
the
configuration
chain
code
and
also
by
the
identity
of
the
the
identity
membership
service
as
well.
B
So
smart
contracts,
so
we
often
hear
that
smart
contracts
on
hyper
ledger
are
called
chain
code
and
that
for
the
most
part,
that's
true.
Smart
contracts
are
business
agreements
that
are
encapsulated
in
code,
so
I
ideally,
the
smart
contracts
will
be
able
to
build
applications
and
will
be
able
to
execute
transactions
between
users,
so
a
smart
contract
versus
chain
code.
B
B
B
The
interpreter
this
has
the
code
in
the
business
logic
and
then
there's
the
accept
and
reject
correctness
is
evaluated
and
we
look
at
the
state
delta
and
then
any
types
of
ordering
information
that
needs
to
be
sent
and
a
little
bit
about
some
of
the
policies.
So
policies
are
implemented
by
different
levels
in
the
hyperledger
fabric
network
and
each
policy
governs
different
aspects
of
how
the
network
operates.
So
we
have
the
system
channel,
and
this
is
the
consortium,
membership
and
blockchain
structure.
B
B
What
an
order
organizes
and
governs?
We
can
see
right
here
and
what
a
consortium
organizes
and
governs
over
here.
So
we
see
the
system
channel
that
we
just
talked
about
with
the
blockchain
structure
consensus
our
application
channel,
also
with
the
consensus
we
can
see
here
as
far
as
what
our
consortium
organ
organizat
or
organizes
and
governs
smart
contracts,
leak,
ledger
data
events,
also
channel
membership
and
application
channel.
Ultimately
also
participates
in
consensus.
B
And
the
when
an
endorsement
policy
is
set
up.
Quite
often,
it
defines
how
many,
how
many
sets
of
organizations
are
required
to
endorse
a
transaction
in
order
to
be
valid,
so
we've
got.
That
is
that's
required.
We
need
to
know
who
is
going
to
participate
in
the
validation
of
that
transaction
and
that's
described
or
set
during
the
chain
code,
installation,
so
principles
are
described
also,
the
msp
represents
required.
B
Ids
role
represents
one
of
the
four
aspects:
either
you're
a
member
you're,
an
admin,
a
client
or
a
peer,
and
here
is
some
endorsement
policy,
syntax
right
here.
So
in
the
syntax
language,
you
can
just
see
some
examples
of
it
here.
So
here
is
an
admin,
an
administrator
of
a
member
of
a
client,
a
peer.
B
So
again,
a
membership
service
provider
is
that
mechanism
that
provides
the
members
their
sets
of
roles
and
permissions
on
the
hyperledger
network
and
the
implementation
of
the
msp
is
required
and
it
sets
it.
It
is
a
set
of
folders
that
are
added,
and
we
can
see
here.
We
have
local
msps
and
we
also
have
channel
msps.
B
And
the
certificate
authority
issues
identities
by
generating
a
public
key
which
forms
that
that
certain
key
pair
that
can
be
used
to
prove
an
identity.
As
everybody
knows,
with
key
pair
encryption,
there
is
a
public
key,
a
public
key.
Everybody
is
aware
of
your
public
key.
That
is
how
that's
almost
like
your
address
that
we
use
to
encrypt
the
message
to
you
and
because
a
private
key
can
never
be
shared
publicly.
It's
a
its
mechanism
is
required
to
enable
proof
which
is
where
the
msp
comes.
B
In,
for
example,
a
peer
uses,
a
private
key
to
digitally
sign
or
endorse
a
transaction.
So
you
use
your
private
key.
Essentially,
the
public
key
is
used
to
enter
the
message
and
send
it
to
the
intended
party,
and
then
the
intended
party
uses
its
private
key
to
decrypt
the
message,
and
it's
also
because
that's
a
private
key.
B
It
is
also
considered
a
digital
signature
as
well,
and
the
msp
is
that
mechanism
that
allows
that
identity
to
be
trusted,
because
trust
is
a
big
big
part
of
hyperledger,
as
well,
so
to
be
trusted
and
recognized
by
the
rest
of
the
network
without
ever
revealing
of
the
member's
private
key.
So
the
private
key
is
meant
to
be
kept
private.
B
Also,
the
msp
turns
an
identity
into
a
role
by
identifying
specific
privileges
as
an
actor
on
the
notre
channel,
and
note
that
when
a
user
is
registered
with
with
fabric
ca,
a
role
of
admin,
peer,
client
or
member
must
be
associated
with
that
user.
So,
when
we're
registered
on
there,
we
do
need
a
role.
B
And
the
role
of
the
system
administrator,
so
this
is
one
of
one
of
the
topics
we're
going
to
talk
about
some
available
career
choices
in
the
hyperledger
world,
so
a
system
administrator
administers
and
interacts
with
the
chain
code.
The
application
manages
peers
and
operates
basic
certificate
authority
level
functions
so
being
a
hyper
ledger.
Sister
admin
entails
an
understanding
of
the
networked
topology.
B
B
You
talk
about
ibm.
All
those
ibm
products
need
system
administrators.
Those
are
the
experts
in
in
the
system.
They
will
do
the
installation
they
will
do
the
updating.
In
fact,
right
here
we
talk
about
some
main
tasks
of
a
system
administrator
for
hyperledger,
so
application
lifecycle
management,
yes
I'd,
say,
but
this
is
more
infrastructure,
related,
install
and
configure
the
network.
So
you
have
the
way.
Hyperledger
is
set
up.
It's
it's
very
cont.
It's
container
based,
so
you've
got
to
download
the
containers
the
docker
containers
docker
installed.
So
there
there's
there's.
B
There's
something
to
learn
in
order
to
ramp
up
to
be
a
system
administrator.
You've
gotta
have
good
diagnostic
and
troubleshooting
patients,
including
the
reading
of
the
correct
logs,
and
you
need
to
understand
about
membership
service
provider
and
also
general
network
maintenance
and
operations,
and
so
some
technical
requirements.
We've
already
talked
about
some
of
these
from
the
technical
standpoint
system
administrator,
should
acquire
acquire
basic
knowledge
of
the
linux
command
line.
You
can
install
hyper
ledger
through.
I
think
it's
ubuntu
for
windows.
B
I
I've
actually
done
it,
but
again
that
gives
you
a
linux
command
line.
Shell
or
the
bash
shell.
Certainly
docker
docker
will
help
docker,
for
anyone
that
doesn't
know
is
a
runtime
for
containers
and
containers
are
like
virtualized
applications,
but
they're,
not
full
virtual
machines.
They
are
only
the
application
and
its
dependencies
and
then
a
docker
runtime
is
required.
B
We
talked
about
nosql
nosql
databases,
so
couchdb
certainly
is
a
because
that
is
that
manages
the
world
state
of
the
ledger.
It's
good
to
know
about
couchdb
and
running
queries
against
it
and,
of
course,
blockchain
and
distributed
ledgers
to
have
a
basic
knowledge
of
that,
or
even
a
intermediate
knowledge
of
that
there
is
a
certification
exam
for
system
administrator.
So
please,
later
on,
consult
back
to
this
webinar
for
more
information.
I
believe
bobby
is
going
to
follow
up
to
with
information
on
the
certified
hyper
ledger
fabric
administrator.
B
And
the
role
of
the
fabric
developer.
So
in
comparison
with
the
system
administrator
developers,
primary
task
is
to
work
on
on
the
major
component,
which
is
the
smart
contracts
for
the
chain
code.
So
the
developers
are
building
the
applications
that
are
running
on
hyperledger,
so
developers
are
required
to
design
develop
and
deploy
a
hyperledger
chain
codes
on
a
pier.
So
it's
very,
very
similar
to
application
development.
All
those
rules
of
application
development
are
are
still
there.
B
All
of
those
best
practices
still
apply
all
of
those
same
things
that
developers
struggle
with
meaning
understanding
the
requirements
of
the
customer
testing.
Automated
testing,
updating,
that's
all
still
there
as
well
and
developer
tasks
would
be
to
define
the
the
the
features
in
the
transaction
functions.
Certainly
execute
simple
queries,
create
complex
queries,
define
assets
and
use
key
value
pairs.
So
if
we
have
an
asset
on
a
hyperledger,
hyperledger
can
maintain
really
any
item
as
an
asset.
B
And
hyperledger
developers
must
have
that
that
solid
foundation
of
of
programming
in
their
background
languages,
such
as
javascript,
which
is
reasonably
popular
and
not
really
too
difficult
to
learn,
I'm
sure
there
could
be
some
I'm
sure
there
could
be
disagreements
with
that.
Job
has
been
very
popular
if
you've
gotten
into
programming
at
all.
I'm
sure
you've
had
some
experience
with
java.
It
really
is
a
it's
a
great
language
and
I
believe,
even
still
today,
it
is
still
the
largest
market
share.
B
Go
is
another
one,
so
go
is
becoming
very
popular.
Interestingly
enough,
I
heard-
and
I
heard
this
recently
not
all
that
long
ago-
that
google
does
not
use
java,
they
use
go
so
go
may
have
been
developed,
and
I
don't
know
the
history
here,
but
go
may
have
been
developed
as
an
alternative
job
anyway
python
as
well.
B
B
So
so
some
additional
training,
resources
and
bobby
will
have
the
information
on
this.
But
you
can
see
here,
hyperledger
fabric
for
system
admins
for
developers,
hyperledger
sawtooth,
so
sawtooth
is,
is
another
product
similar
very,
very
similar,
almost
a
specialized
blockchain
or
distributed
ledger
product.
B
A
A
B
B
B
Well,
if
you
are,
if
you
want
to
use
the
blockchain,
obviously
you
want
to
run
applications
and
transact
and
have
the
the
blockchain
for
tracking,
say
your
inventory
tracking
chain
of
custody
supply
chain.
Then
you're
certainly
going
to
need
developers
in
order
to
build
that
those
applications,
no
question
about
it.
B
There
system
administrators
are
obviously
needed
to
maintain
the
network
hard
to
say,
though
I'm
gonna,
I'm
gonna
I'll,
go
out
on
the
limb,
and
I
think
I
might
get
some
disagreement
here,
but
I'm
gonna
say
the
system
administrator
is
not
a
full-time
job
that
one
system
admin
can
have
can
be
the
owner
of
more
than
one
product.
That
seems
to
be
even
for
the
most
complex
systems
and
again
I
used
to
work
for
ibm
and
believe
me.
Everything
right,
ibm
and
easy
are
never
used
in
the
same
sentence.
Almost.
B
Never
so,
and
I
never
met
anybody
completely
dedicated
to
a
pro
to
a
system
or
two
enterprise
software
enterprise
hardware.
That
was
always
in
there
doing
something
so
I'll,
say
the
developer.
Developing
the
applications
is
slightly
more
important
because
we
possibly
the
developer,
can
also
be
the
part-time
system
administrator.
As
well
yep,
it.
A
Makes
perfect
sense?
Okay,
we
got
one
that
came
through
the
questions,
which
is
great.
Thank
you
for
doing
that.
This
comes
from
malendu
and
it
says
how
do
you
manage
private
keys
on
on-premise
setups
and
then
it
basically
goes
on
to
say:
online
hsms
are
good
to
go,
but
on
premise
we
found
that
kind
of
tricky.
B
And
for
for
the
the
private
key
maintenance
on
on-premises
is
that
the
is
that
that
is
exactly
right?
Jim,
there
is
a
ap.
Let
me
let
me
think
how
we
did
that
in
the
in
the
past,
the
the
maintenance
of
the
private
key.
There
is
a
client.
There
is
another
node
called
a
client
node,
and
I
may
have
to
follow
up
a
little
bit
on
this.
A
Okay,
so
london,
you
want
to
raise
your
hand
and
ask
that
any
follow-up
to
that
question,
or
are
you
good
and
if
I
don't
see
any
weighing
in
here,
I'm
going
to
go
ahead
and
turn
it
over
to
up
there's
raised
hand
perfect,
so
I'm
going
to
hand
the
mic
over
to
you
great
okay,
okay,
go
ahead
and
maybe
follow
up
on
that.
This
is
good
for
testing
too.
So
I
really
appreciate
your
help
on
that.
Yeah.
C
C
So,
like
I
said,
I
know,
we've
we've
looked
at
a
couple
of
options:
I've
tried
to
say
integrated
to
things
like
vault
there's,
a
native
docker
secret
support
for
quantization
yeah.
So,
but
we
found
that
when
you're
working
with
the
middleware
using
fabric
sdk,
but
I
use
node.js
or
for
go,
we've
kind
of
find
it
tricky
to
secure
that
private
key
right.
That
looks
like
there
are
options
to
integrate
it
to
vault.
But
it's
not
out
of
the
box
right.
C
B
Yeah
like
this
well,
the
custom
definitely
just
brought
up,
so
that
would
also
be
a
solution
as
well.
Thank
you
for
for
reminding
me
of
that.
The
we
do
a
lot
of
work
with
ibm.
I
still
have
a
lot
of
connections
there
and
obviously,
all
of
those
instances,
almost
always
almost
100
percent,
are
running
on
the
ibm
cloud.
So
and
so,
but
that's
not
your
situation
so
on-prem,
so
that
that
would
be
a
way
to
go.
B
This
is
a
great
question
to
escalate
up
to
the
community,
I'm
not
trying
to
push
you
off
or
anything,
but
certainly
the
hyperledger
community.
We
might
be
able
to
get
a
little
more
information
on
that
or,
if
anyone
else,
because
I
I
have
not
encountered
that
in
either
my
training
or
any
of
installation
or
application
development
for
hyperledger.
But
that's
a
great
question.
B
A
A
B
A
And
that's
maybe
something
we
can
take
off
the
line.
So
I
think
at
this
point
jim,
let
me
go
ahead
and
bring
bobby
out
to
the
stage
here
and
then
I'll
turn
it
over
to
her
to
do
her
presentation
and
then
once
bobby
comes
on
and
does
her
presentation,
then
what
I'd
like
to
actually
do
is
test
a
few
minutes
in
the
room
for
the
networking,
and
so
if
anyone
can
stay
on
for
that,
that
would
really
be
appreciated
because
that's
a
good
test
as
well.
A
A
C
And
how
do
I
share?
Oh,
I
see
so
I
want
to
thank
you,
john
for
having
me
speak
today.
It's
a
pleasure
to
come
out
for
the
denver
meetup,
I
hope
soon
in
the
future.
I
could
actually
come
to
denver
and
meet
up
with
you.
That
would
be
nice,
so
we've
heard
a
lot
about
the
administrators
and
the
developers
and
a
lot
of
oh,
let's
develop
a
project.
Let's
talk
about
this
and
that
I
want
to
tell
you
how
to
actually
get
involved.
A
C
A
C
C
The
wiki
page
is
where
the
people
who
are
developing
solutions
and
want
to
learn
more
about
the
solutions
go.
I
I
call
it
to
to
develop
or
play
so
I'm
going
to
I'm
sorry
if
I
have
to
turn
to
look
at
my
other
screen,
so
basically
what
what
the
wiki
page
is
it's
organized
by
the
projects
and
tools
and
then
the
special
interest
groups
and
working
groups
that
use
those
projects
and
tools.
C
So
if
you'll
look
it's
just
a
simple
wiki.hyperledger.org,
and
this
is
the
page
you'll
show
up
on-
and
this
is
the
landing
page
for
hyperledger
as
you'll
see
they
have
a
calendar
of
public
meetings
which
gives
you
a
list
of
calls
that
happen
every
day
that
the
community
is
invited
to
join.
So
anyone
listening
to
this
call
can
join
any
of
these
calls
by
looking
at
the
calendar
and
seeing
what's
available.
C
So,
for
instance,
tomorrow
is
a
grid
community
meeting,
so
you
would
join
the
call
and
and
introduce
yourself
and
maybe
see
what
needs
the
grid
community
has
or
there's
others
as
well,
so
the
projects
are
listed
in
the
top
and
you
can
see
the
different
projects.
Each
one
has
a
similar
web
wiki
page
set
where
it
has
the
information
about
the
project
itself.
C
I
run
the
hyperledger
learning
materials
working
group
and
I'm
going
to
select
that
real,
quick
and
that
would
be
a
group.
I'm
sorry,
we
drop
down
group
here
and
you
would
see
the
list
of
groups
and
we're
going
to
go
over
them
in
a
minute,
because
I
saw
somebody
in
the
chat
from
telcom.
So
I
want
to
talk
about
that
group
as
well.
C
Why
I'm
focusing
on
the
learning
materials
working
group
is
because
we
have
libraries
of
information
for
you
to
access
here
on
our
home
page
as
well
as
what
we
find
really
important
every
monday
morning
is
a
list
of
what's
going
on
in
the
community,
so
you
can
see
the
different
meetups
that
are
happening.
Here's
our
meetup
right
here,
that's
listed
for
today.
You
can
see
what's
happening
tomorrow,
and
these
are
not
the
regular
project
or
working
group
calls.
C
These
are
meetups
like
john
has
set
up
for
us
today
then
there's
the
special
events.
Hyperledger
is
celebrating
their
five
years
event
and
they
have
one
more
discussion
panel
and
then
a
networking
session
that
everyone
is
invited
to.
I
hope
I
see
everybody
out
at
that
networking
session
and
again,
the
live
links
are
on
this
wiki
homepage,
where
you
can
just
go
to
the
learning
materials
group
and
get
this
information.
C
Also
on
this
page
is
how
to
get
involved,
which
is
probably
the
most
important
thing
for
people
who
are
new
to
the
community.
So
if
you
click
the
new
members,
welcome
page
it'll
show
you
the
four
steps
to
get
involved
and
they're
simple.
The
first
thing
you
do
is
need
to
get
a
linux
login,
which
is
just
verifying
your
email.
C
So
if
you
selected
that
it
will
show
you
where
to
go
to
get
your
linux
login
and
once
you
have
that
you
can
log
into
a
wiki
page,
as
you
see
my
face
here,
that's
because
I'm
logged
in
and
once
you're
logged
in
you
get
that
toolbar.
That
has
the
edit
and
all
the
other
information.
So
now
you
can
edit
and
join
these
wiki
page
discussions.
C
You
can
put
your
name
in
the
community
pages
and
you'll
see
how
to
get
involved
further,
so
to
get
a
linux
login
and
then
you
can
edit
the
wiki
pages.
But
again
you
don't
know
what
wiki
page
edit
or
what
you
need
to
do.
So
you
have
to
join
call.
So
once
you
select
this,
you
go
into
the
community
mailing
list
section
and
you
would
have
different.
You
could
do
it
join
different
groups.
C
You
would
select
that
group
and
there
would
be
a
button
here
that
said
join
now
and
once
you
select
that
button.
All
that
means
is
that
you're
going
to
be
involved
in
the
mass
mailings
that
go
out
so
you'll
get
notified
when
that
group
meets
or
or
other
information.
So,
for
instance,
the
I'm
going
to
see
if
I
have
telecom
here
for
the
people
who
are
on,
I
should
so
the
telecom
special
interest
groups
meet.
They
have
discussion
boards,
where
you
can
ask
your
questions.
C
The
event
was
cancelled
for
december
31st
and
you
can
go
into
their
main
meeting
so
once
you
join
this
group
you're
involved
in
all
of
these
conversations,
so
I'm
going
to
go
back
to
the
learning
materials
working
group
home
page,
and
so
these
are
the
events
that
are
happening
and
to
get
the
linux
foundation
join
the
calls
and
then
how
to
get
involved.
I
already
showed
you
a
little
bit
about
that.
You
just
sorry.
You
just
have
to
join
a
call
and
they're
listed
again
on
the
hyperledger
home
page.
C
It's
right
here,
calendar
of
public
meetings,
and
then
you
can
select
the
meeting
you
want
to
join
by
just
going
to
again
I'm
going
to
go
to
picking
on
supply
chain
now
selecting
this
zoom
link,
putting
it
in
a
browser
and
you're
good
to
go
and
introduce
yourself
or
don't
introduce
yourself,
but
to
get
involved.
It's
better.
If
you
get
involved
in
the
conversations.
C
C
If
you
take
both
of
those
free
courses,
you
can
sit
in
and
take
the
block
blockchain
for
business
certificate
course
and
get
a
certificate
same
thing
with
the
other
certificate
courses,
which
is
the
administrator
and
again
from
our
home
page.
All
of
those
courses
are
linked,
so
you
can
see
how
to
get
the
program.
Information
sign
up
register
for
the
course
and
take
the
test.
C
So,
if
you're
interested
in
any
of
those
courses
again,
it
is
on
the
edx
update
on
the
learning
materials
working
group,
a
description
of
all
the
classes
and
links
to
sign
up
for
those
classes,
whether
they're,
the
free
ones
or
the
competency
tests.
Now
what
the
learning
materials
work
in
group
does
is.
We
are
kind
of
like
the
first
editors
on
a
lot
of
these
tests.
I'm
sorry
on
a
lot
of
these
edx
courses.
C
So
again,
that's
one
of
the
roles
of
the
learning
material
working
group
is
to
keep
track
of
what
exams
are
out
there
and
what
competencies
in
the
community
there's
an
enormous
push
for
bilingual
materials.
So
we
are
trying
to
encourage
people
who
can
write
and
interpret
these
materials
to
do
that.
So
we
have
japanese
we're
working
on
the
spanish
version.
C
I
know
somebody's
working
on
the
french
version
and
there'll
be
more
community
information
on
the
learning
materials
homepage
about
that
when
the
actual
groups
are
meeting
to
get
that
task
done
so
again,
these
are
the
edx
courses.
Every
monday,
the
learning
materials
I'm
going
to
go
back
to
our
homepage
show
off
again.
C
So
every
monday
we
meet
and
here's
our
meeting
notes.
We
go
over
what's
going
on
in
the
community
what's
going
on
at
edx.
What
are
the
new
competencies?
What
are
the
exams
coming
out
and-
and
we
talk
about
we're
working
on
again,
the
the
topic
of
this
is
the
learning
materials
working
group.
So
we
talked
about
the
home.
Page
talked
about
the
welcome
page.
We
also
offer
templates,
which
are
formatted
documents
for
you
to
use
if
you're,
creating
hyper
ledger
community
information.
C
So
we
have
a
white
paper
template
a
use
case
template
we
have
graphics
you're
supposed
to
use.
We
have
basic
webinars.
If
you
want
to
develop
an
edx
course
and
on
the
other
side
of
the
templates,
we
do
have
what
we
call
our
resource
library,
which,
which
is
where
we
try
to
collect
the
information
from
all
of
these
groups
that
are
meeting
so
again.
The
projects
and
tools
each
has
their
own
little
library,
with
their
information.
C
We're
talking
about
fabric,
so
I'll
go
to
the
fabric
page
talks
about
the
quarterly
reports.
You
can
see
who's
making
contributions
to
fabric
what
companies
they're
from
what
else
is
the
information
here?
It
shows.
What
are
the
new
is
coming
out.
There's
always
a
link
to
the
quarterly
report
that
they
give
to
the
technical
steering
committee.
So
again,
this
is
just
thumbnail
information
for
you
to
to
get
involved
each
one
of
these
tools
and
frameworks
you
know,
can
use
to
be
updated
by
any.
C
C
So
again,
another
big
initiative
in
the
learning
materials
working
group
is
these
key
terms.
We're
responsible
for
making
a
glossary
for
the
community.
The
department
of
education
is
has
been
asking
for
other
associations.
Edx
wants
it
from
us
as
well,
so
we're
trying
to
gather
as
many
definitions
as
possible
as
a
working
group
and
then
we're
going
to
have
a
meeting
where
we
sit
down
and
decide
what
our
wiki
page
key
terms
will
look
like
a
living
key
term.
C
We
try
to
sum
it
up
on
the
learning
materials
homepage
for
you
each
week,
so,
if
you're
looking
to
get
involved
in
the
community
david
from
hyperledger
supplies
us
with
all
these
great
events
that
are
going
on
in
the
community
and
they're
always
listed
here
with
links
for
you
to
get
in,
I
will
be
in
one
of
the
breakout
rooms.
If
anybody
has
any
questions
on
how
to
get
involved,
if
you
are
still
confused
and
want
to
get
involved,
you
can
always
join
the
learning
material
call
on
every
other
monday.
C
A
Yeah,
that's
wonderful
bobby,
and
thank
you
very
much
for
doing
that.
One
thing
I
would
like
is
if
you
could
put
a
link
to
that
hyper
ledger
url
in
the
chat
here
just
so,
anybody
can
easily
just
pop
it
right
up
on
their
browser
and
then
be
able
to
go
in
there,
so
that
thanks
perfect
bobby
exactly
so
at
this
point,
does
anybody
have
a
question
for
bobby
that
would
be
relevant
to
the
whole
group
and
then
I'll
talk
a
little
bit
about
what
we're
going
to
do
next
about
our
networking
session
here.
A
If
there's
any
problem
exiting
out
of
the
main
presentation
here,
and
so
what
I'd
like
to
do
is
we're
going
to
have
jim
at
one
table
and
then
we're
going
to
have
bobby
at
another
table
and
I'll
label
those
tables
within
the
application
and
then
bobby
and
jim.
If
you
could
each
go
to
a
separate
table
and
then
I'm
also
going
to
have
an
open
discussion
table
so
that
people
can
go
out
there
and
network
and
talk
around
and
the
main
thing.
A
What
I
want
to
try
and
do
with
this
is
really
capture
that
in-person
networking
that
we've
sorely
been
missing,
because
everything
is
virtual
here
and
just
see
how
it
works.
To
reconnect
with
people
talk
about
projects
that
you're
working
on
ask
bobby
about
all
the
great
work.
That's
going
on
with
the
learning
materials
working
group
or
even
the
technical
steering
committee
and
then
check
in
with
jim
and
see.
You
know
how
you
can
get
into
being
a
system
administrator
or
a
developer
for
hyperledger
fabric.
A
So
at
this
point
I'm
going
to
go
ahead
and
end
the
session.
Hopefully
this
puts
everyone
out
to
the
main
room
and
then
what
I'd
like
everyone
to
do
is
just
go
and
pick
one
of
the
couple
tables,
probably
two
or
three
tables
that
we're
gonna
have
out
there
and
then
just
join
in
as
more
of
a
small
group
discussion.
But
one
of
the
things
I
like
here
is
this:
is
an
opt-in
type
of
networking
versus.
