A
So
I
think
it's
going
to
be
a
bit
more,
not
as
interesting
as
the
other
ones,
where
you
have
demos,
because
we
we
have
been
working
mostly
on
the
back
end
and
the
background
of
these
things.
But
I
hope
I
can
provide
a
bit
overview
of
all
the
libraries
we've
made
and
how
they
can
be
also
integrated
by
other
people
in
the
ecosystem.
A
So
I
mean
we
have
been
involved
in
in
fightcoin
for
a
while,
already
almost
like
a
year,
and
we
have
been
working
on
different
areas.
We
did
part
of
the
of
like
things
like
opencl
integration.
We
also
did
the
the
fin
work
for
the
hardware
wallets,
like
ledger
nano
s
and
x,
and
we
have
been
also
working
on
on
web
assembly
and
some
rust
libraries
that
are
being
used
by
some
of
the
wallets-
and
this
is
this
probably
was
called
file,
consigning
tools
and
also
in
on
exchange
integration.
So
we
are
kind
of
like.
A
To
the
final
users,
but
we
are
like
kind
of
running
a
lot
of
the
code
and
providing
libraries
to
people
in
the
ecosystem.
So
if
anyone
anyone
is
like
interested
in
building
up
like
on
top
of
fico-
and
I
mean
you
can
all
also
use
some
of
the
libraries
we
made
and
that
will
simplify
a
lot
of
your
work.
A
So
I'm
going
to
go
like
quite
briefly
on
those,
and
maybe
we
can
later
discuss
where
I
can
answer
some
questions
about
that.
So
I
mean
with
respect
to
ledger
apps,
where
we
made
the
filecam
letter
up
for
nanos
and
x,
and
we.
A
A
We
did
like
also
api
fasting
and
just
before
the
release,
we
went
through
a
couple
of
like
audits,
one
all
it
was
done
by
letter,
the
other
all
it
was
done
by
a
third
party
and,
as
you
have
seen
in
the
previous
presentations,
these
two,
these
two
projects
like
glyph
and
lotus,
have
already
integrated.
So
I
mean
it
should
be
fairly
easy
to
integrate
into
other
components,
given
that
you
have
like
also
support
in
different
languages.
A
Apart
from
that
some
other
projects,
they
need
to
have
access
to
sign-in
tools
that
are
not
just
running
on
a
hardware
wallet,
and
it
also
requires
interaction
with
nodes,
transaction
serializations,
and
things
like
that.
So
we
also
have
been
working
on
this
icon,
signing
tools
that
some
of
the
products
you
you've
been
watching.
They
use.
They
also
use
that
we
provide
a
json
rpc
service
to
connect.
We
also
provide
like
a
sign-in
and
verification,
and
all
these.
A
Were
also
audited
and
you
can
use
them
from
a
lot
of
different
languages,
so
we
provide
like
examples
and
documentation
and
if
you
find
support
so
you
can
use
the
same
library
from
c
java.
Kotlin,
swift,
objective,
c,
filter
and
many
others
and
the
examples
are
not
extensive.
So
we
expose
the
whole
api,
but
we
provide
a
way
of
example
on
how
to
do.
B
A
A
In
addition,
we
have
been
working
on
exchange
integration
so,
and
there
is
a
new
api
that
coinbase
is
like
working
on
that
is
called
rosetta.
That's
a
golang
based
sdk
that
allows
you
to
kind
of
like
abstract
away
different
chains
and-
and
it
simplifies
all
the
process
of
integrating
with
an
exchange,
but
also
provides
like
the
ability
to
to
query
the
the
chain
and
also
get
information
similar
to
what
the
block
explorer
would
do.
What
we
did
there
is
like.
We
have
a
dockerized
deployment
for
this
rosetta
proxy.
A
It
allows
some
simple
caching,
but
we
are
likely
going
to
improve
that
like
pretty
soon
hopefully,
and
also
allows
for
actual
type
resolution
like
food
chain
indexing.
It
allows
you
to
get
access
to
metadata
like
nonsense,
gas
estimation
something
like
that,
and
we
pro
we
test
that
extensively
in
in
our
testing
infrastructure.
So
we
have
like
full
node
ci.
We
have
access
to
low
level
traces.
So
it's
not
just
like
the
transaction
itself,
but
we
understand
exactly
how
the
transaction
was
executed
inside
the
node.
A
So
even
in
the
case
of
multi-six,
it's
very
easy
for
exchanges
to
understand
if
a
proposed
was
actually
producing
a
change
or
it
was
like
one
of
the
many
purposes
that
are
necessary
to
get
to
the
change
in
the
balance.
So
all
this
helps
to
have
like
a
clear
account,
reconciliation,
so
exchanges
or
projects
that
rely
on
rosetta
can
like
understand
how
the
history
of
the
full.
B
A
Works
out
and
understand,
like
all
the
changes
in
all
the
accounts,
similarly
to
our
lock
explorer,
but
also
with
a
bit
more
detail
because
of
the
access
to
traces
and
what
we
are
planning
to
do
next.
Well,
it
depends
I
mean
we
are
like
working
with
many
products
in
different
areas,
and
there
are
some
aspects
that
we
have
like
quite
a
bit
of
experience
like,
for
example,
they
are
the
aspect
of
remote
designers.
A
So
we
we
have
a
project
where
we
are
like
using
remote
signs
for
proof
of
stake,
and
we
think
that
it
could
be
useful
to
use
also
in
icon
for
all
the
miners.
And
so
we
are
like
kind
of
finalizing.
This
traction
based
device
where
we
have
like
kind
of
an
industrial
device
like
data
center,
ready
that
has
like
high
performance
and
we
we
can
provision
keys
from
a
ledger
to
this
device
and
offload
and
later
have
like
some
interesting
mechanisms.
But
we
don't
have
to.
A
Device
like
hanging
from
a
data
center,
we
are
also
thinking.
A
Some
of
some
of
the
latency
issues
that
we
have
been
working
on
so
do
a
full
chain
indexing
and
caching
and
having
some
kind
of
like
a
nice
api
on
graphql
and
with
reorg
support.
So
if
the
change
changes,
we
will
do
the
full
reindexing
for
only
the
special
parts
and
some
other
concepts
like
improving
a
bit
more
designing
tools
and
and
maybe
working
on
some
additional
hardware
and
wallet
so
forth.
These.
A
Are
like
discussing,
but
we
would
be
happy
to
to
help
in
all
these
areas
that
are
basically
in
the
area
of
expertise
of
our
team.
So
I
would
like
very
briefly
on
on
all
the
things
we've
been
doing,
but
I'm
happy
to
to
go
through
anything
in
more
detail,
or
maybe
us
like
answer
questions,
but
in
a
way
we
didn't
prepare
like
a
demo,
because
I
think
that
you,
you
have
seen
in
a
way
that
our
work,
through
the
demos
of
others
like
in
all
the
integrations
that
we
help
with.
B
Yeah
make
sense
yeah.
I
can
ask
you
a
few
questions,
so
yeah
of
course,
number
one.
What
are
the
kinds
of
applications
you're
seeing
built?
So,
of
course,
things
like
glyph
and
others,
but
anything
else
that
you've
seen
being
built
with
the
tooling.
A
So,
as
far
as
we
know,
so
there
are
a
few
exchanges
that
are
like
relying
on
these
also
glyph
and
lotus
are
already
integrating
with
these
libraries
and
tools.
I
I
think
that
they
are
like
a
new,
a
few
new
products
that
are
also
relying
on
this
because
of
the
impact
and
like
the
issues
that
we
have
seen
in
github,.
A
In
the
presentation
is
that
we
have
been
working
with
some
other
people
in
protocol
labs
on
the
payment
channel
support
so,
for
example,
our
signing
tools
also
support
payment
challenge
and
the
whole
workflow,
not
only
multi-sig,
so
we
provide
like
web
assembly
support
for
that,
and
we
have
been
like
interacting
with
some
people
in
protocol
labs
on
the
browser
extension
that
supports
retrieval
operations,
but
I'm
happy
to
I
mean
I
think
this
is
kind
of
like
the
the
early
stages,
and
probably
these
tools
will
like
probably
need
like
a
bit
more
feedback.
A
The
I
think
the
advantage
of
of
these
libraries
is
that
they
cover
like
most
of
the
basic
workflows
and
they
have
been
audited,
so
they
can
be
used
as
a
kind
of
like
safe
choice
when
dealing
with
like
cryptography
or
operations
like
that.
B
Yeah,
that's
awesome.
I'm
curious
if
you
could
show
us
just
like
the
github
repos
of
the
tools
just
so
that
developer
might
get
familiar
with
them.
A
So
tools
is:
is
a
github
repo
where
you
you
can
find
like,
as
you
can
see
it's
being
used
by
a
lot
of
people,
and
here
you
basically
have
a
rust
native
library
that
has
support
for
like
6p.
This
is
kind
of
like
a
bit
out
of
date,
so
via
a
multisig
and
vls
is
already
supported.
Also,
you
have
this
rust
library
compile
as
well
assembly
so
in
web
assembly.
A
You
can
use
all
these
cryptography
directly
in
the
browser,
and
then
you
have
like
this
json
rpc
server,
where
you
can
use
that
for
interacting
with
the
nodes,
or
there
is
also
a
service
that
does
something
similar
to
what
we
did
for
rosetta
in
the
exchange
integration
and
then
in
the
in
the
same
repository.
You
have
a
lot
of
examples
for
each
of
these
languages
and
how
the
integration
happens.
So,
for
example,
you
can
connect
from
your
browser
to
webassembly
and
have
like
all
this
functionality
and
the
same
for
all
these
languages.
A
We
we
provide
like
very
simple
examples
on
how
to
connect
from
any
implementation
written
in
that
language
to
our
library.
So,
for
instance,
if
you
want
to
do
something
for
mobile
phones
using
objective-c
or
or
swift,
there
is
a
way
of
connecting
to
our
rust
implementation
that
has
support
for
bls,
xp
transaction
serialization
on
all
these
features
that
will
rediscuss
and
in
addition,
of
course,
you
have
like
a
continuous
integration
and
we
have
like
a
kind
of
like
a
very
good
coverage
and
and
all
this.
A
So
apart
from
that,
we
have
like
obviously
the
ledger
app,
even
though
this
is
kind
of
like
something
that
probably
is,
is
interesting
and
only
for
for
people
that
might
want
to
look
at
the
code,
because
the
whole
development
process,
once
the
ledger
app
is
published.
It
goes
directly
to
letter
and
they
take
ownership
so
and
you
won't
be
able
to
kind
of
like
ship
a
new
application.
A
It
has
to
go
through
ledger
because
of
restrictions
from
the
security
point
of
view,
but
the
ledger
app
also
is
available
in
case
someone
wants
to
add
additional
features.
We
maintain
that
actively
and
then
we
have
like
some
repositories,
for
example,
for
rosetta,
where
we
keep
like
all
the
things
so,
for
example,
for
rosetta
proxy,
which
is
this
tool
that
I
I
was
describing
you.
You
can
also
get
access
to
this.
We
have
like
kind
of
like
constant
releases,
and
we
have
also
continuous.
A
A
So
here
here
there
are
like
a
lot
of
components
that
are
available.
For
instance,
I
think
the
the
recent
integration
into
the
lotus
cli
was
particularly
using
probably
like
letter
five
and
go.
That
is
a
complete
communication
and
abstraction
from
like
the
device
and
any
any
go
library,
and
we
have
like
something
similar
for
us
and
we
have
some
the
same
thing
for
js.
B
Yeah,
that's
awesome,
that's
really
cool!
There
are
many
people
making
web
apps
out
there
that
need
to
sign
transactions
so
for
those
web
developers
out
there
is
there
a
specific
module
you
recommend
using?
That
shows
maybe
like
the
example
code
on
how
to
call
platform
setting
tools
and
things
like
that.
A
Yeah,
so
this
is
the
the
one
that
most
people
will
be
using
file
consignment
tools.
So
if
you
go
to
examples,
you
will
have
like
examples
on
how
to
use
web
assembly
in
the
browser
or
directly
node,
and
then
here
you,
you
have
like
different
different
ways
of
doing
and
for
ffi
the
same.
You
have
like
examples
in
c
c
flutter
and
go
so
I
mean
this
is
this
is
the
point
where
you
probably
want
to
look
at
the
examples
we
we
have
like
been
like.
B
A
A
bit
of
like
a
rebranding
on
the
website
so
soon
we
will
have
like
all
the
documentation
published
there
like
probably
next
week,
so
there
you
can
find
also
some
some
of
the
documentation,
but
otherwise
we
have
like
the
documentation,
is
active
here
like
in
markdown.
We
need
to
kind
of
like
restructure
that,
but
here
you
have
like
all
the
examples
on
how
to,
for
example,
do
key
derive
or
carry
out
from
seed
and
how
to
serialize
the
transaction
and
communicate
with
the
node.
So
all
the.
A
Pieces
that
anyone
that
is
building
on
top
of
icon
needs
to
sign
or
use
a
ledger
or
anything
is
all
here,
even
if
that's
in
a
mobile
device,
it's
always
kind
of
documented,
and
we
have
like
continuous
integration
for
all
these
cases.
So
you,
you
can't
see
that
you
can
see
that
that's
kind
of
like
working
and
being
tested
so
find
this
to
master.
A
B
Awesome
that
is
really
really
great
and
and
anomaly
organized
repo.
By
the
way
that's
going
to
make
it
super
easy
for
everybody
to
to
use.
Maybe
a
quick
question
on
on
audits.
Of
course,
all
this
kind
of
code
is
super
critical
and
whatnot.
Can
you
maybe
mention
like
what
a
audit
flow
there
has
been
or
will
be,
and
so
on.
A
A
So
we
went
through
that
process
and-
and
there
were
like
many
many
important
findings,
like
kind
of
like
a
lot
of
things
that
we
could
improve.
So
we
we
did
all
that.
We
also
have
like
some
interesting
tooling
for
fusing.
So
fasting
means
that
we
we
send
a
lot
of
like
random
data,
to
the
tool,
to
the
point
that
we
like
check.
The
coverage
of
the
whole
application
is
like
really
high
and
that
we
don't
have
like
bugs
in
very
odd
corner
cases.
A
So
we
do
that
not
only
for
fight
and
signing
tools,
but
we
also
have
like
the
whole
infrastructure
for
the
ledger
app
and
in
the
case
of
the
ledger
up.
There
is
something
also
kind
of
like
interesting.
We
have
our
own
emulation
tool
where,
for
every
time
we
make
changes-
and
this
was
also
part
of
the
audit-
and
we
run
like
an
integration
test
where
we
run
and
simulate
it
up
and
where
we
check
that
everything
is
working
and
even
the
screen
has
not
changed
and
we
we
check
that
all
the
values
are
correct.
B
A
Very
structured
workflow
for
all
these
things
and
on
top
of
that
obviously
letter
does
their
own
homework
and
verifies
that.
So,
if
you
see,
for
example,
the
the
file
coin
app
at
the
moment
is
like
fork
by
letter
and
that's
that's
what
we
need
to
kind
of
like
follow
now
anytime.
We
need
to
make
a
change.
We
need
to
kind
of
like
said
it's
an
a
pull
request
to
ledger
and
they
will
review
the
code
again,
but.
B
B
Yeah,
that's
awesome.
It's
really
cool
to
see
a
an
emulator
for
for
doing
testing
with
all
that.
That's
super
cool.
A
B
Yeah
and
and
then
maybe
you
mentioned
kind
of
remote
signer
support
as
a
thing.
That's
gonna
come
in
the
future.
I
know
that's
something
that
a
lot
of
people
might
be
interested
in.
Maybe
tell
us
a
little
bit
about
that.
B
A
Case
what
we
are
doing
is
we
are.
We
are
considering
so
the
problem
I
mean
we
I
can
tell
like
we
did,
that
for
a
few
other
projects
already
each
product
is
slightly
different.
Basically,
the
the
problem
we've
seen
in
the
field
is
that
many
people
are
are
kind
of
relying
to
the
solution
that
is
available.
That
is
like
having
a
ledger
in
the
data
center,
but
the
devices
are
actually
consumer
devices
and
they
might
not
have
first
the
computing
power
to
run
things
like
a
vls
with
low
latency
and.
B
A
Have
been
trying
to
find
something
in
the
middle
and
ledger
has
a
very
good
feature
that
is
like
you
have
like
physical
security.
So,
even
if
you
get
access
to
the
device,
you
can
extract
the
keys,
but
actually
for
someone
like
a
minor.
The
main.
The
main
problem
is
logical.
Security
is
not
so
much
of
getting
access
to
the
device
where
in
a
data
center,
probably
you
have
like
already
physical
security
like
two
eyes
at
the
door
that
don't
let
you
get
in
and
so
in
most
cases
the
main
issue
is
physical
security.
A
B
A
A
B
A
That
what
we
are
trying
to
do
is
to
kind
of
provide
software
for
these
devices.
We
we
are
not
in
the
hardware
business,
so
people
can
source
the
devices
and
and
use
them
basically
in
in
a
very
quick
way.
It
would
be
like
your
something
similar
like
an
industrial
quality,
raspberry
pi
that
you
combine,
you
can
install
the
software.
You
have
a
secure
boot.
You
sign
the
firmware
with
your
own.
B
B
That's
awesome:
that's
really
really
cool.
I
think
a
lot
of
a
lot
of
folks
are
going
to
going
to
be
very
excited
about
those
kinds
of
tools:
lots
of
different
kinds
of
applications,
we'll
want
that
one.
This
has
been.
This
has
been
awesome.
Thank
you.
So
much
for,
for
this
talk,
super
illuminating,
I'm
sure
a
lot
of
people
that
are
either
already
using
or
will
use
the
tooling
will
find
it
super
useful
and
thank
you
so
much
for
making
making
the
tools.
B
These
tools
are
super
useful
and
valuable
for
a
lot
of
a
lot
of
people.
So
thank
you
very
much.
