A
Of
course,
there
are
parking
lots
all
around
the
area
here
so
feel
free
to
make
use
of
that
and
I'm
glad
that
you're
all
here
so
I'm
gonna
introduce
Kim
first,
that
okay,
oh
yeah,
okay,
so
so
this
is
our
first
time
at
atlas.
Work
base,
and
so
we
wanted
to
first
of
all,
thank
Atlas
for
letting
us
use
their
space,
and
we
brought
along
kim
kim
is
kim,
is
part
of
atlas
she's
in
tuk
a
little
bit
about
atlas
and
for
those
of
us
that
are
looking
for
a
place
to
work.
B
B
Looking
forward
to
getting
to
know
you
all
over
the
time
that
you're
here,
my
name
is
Kim
and
I'm
responsible
for
sales
and
marketing
here
at
Atlas
and
I
just
wanted
to
introduce
you
to
the
concept
and
invite
you
to
come
and
spend
a
day
working
for
working
at
Atlas,
oh
I'm,
not
so
good,
a
follow-up
email
about
that.
So
Atlas
is
two
things
who
spends
time
working
in
a
coffee
shop.
Anyone
everyone
pretty
much
so
the
first
stop
the
first
half
of
that.
B
This
is
called
the
lounge
think
of
it
as
the
coffee
shop
with
power,
privacy
and
a
secure
internet,
something
that
most
of
you
suckers
certainly
do
not
have
this
side
that
we're
on
now
is
called
the
concourse.
It's
our
co-working
offer,
and
the
thing
that's
different
about
Atlas
is
thing
to
keep
in
mind.
Is
that
a
true
shared
economy
model?
B
So
you
pay
for
the
time
you
use
and
you
select
the
place
where
you
want
to
work
each
time
you
come
in,
so
it's
not
as
though
you
pay
for
a
square
box
for
30
days
like
a
lot
of
co-working
spaces,
you
use
it
very
different.
It's
it's
like
a
reach
down
car,
for
example,
reserve
the
cup
grab
the
car.
When
you
need
it,
you
drive
where
you
want
to
go.
You
park
you
get
out
of
the
car
and
you
leave
it
and
five
minutes
later.
C
So
I
will
also
try
to
speak
loudly,
and
hopefully
everyone
will
be
able
to
hear
me
so
so
rich
was
referring
to
my
group,
which
is
partnering
with
the
hyper
ledger,
a
group
in
presenting
this
event.
This
is
the
cryptocurrency
traders
of
Seattle
there's
a
few
familiar
faces
here
in
the
audience.
That
I
think
is
symbolic
of
why
it
makes
sense
for
us
to
partner
up
being
that,
you
know
if
you're
saying
that
you're
only
interested
in
blockchain,
but
not,
for
example,
Bitcoin.
C
That's
like
saying,
say,
20
years
ago
that
you
were
only
interested
in
HTML
and
not
the
web.
You
can't
have
Bitcoin
without
blockchain
and
many
of
the
things
that
Bitcoin
is
doing
to
change
the
world
economy
and
the
way
that
people
transfer
value
and
goods
very
much
goes
hand
in
hand
with
blockchain
that
they
need
each
other.
So
we
feel
like
no
matter
what
at
minimum
we
have
common
interests.
C
I
think
that
if
you're
interested
in
really
learning
more
about
how
to
invest
in
Bitcoin
and
various
alt
coins,
it's
a
great
group
where
you
can
find
like-minded
people
to
ask
questions
and
share
ideas
with
and
make
friends
with.
So
you're
welcome
to
to
join
our
meetup.
We're
going
to
have
our
next
one
on
August
6th
on
Monday
here
in
the
space
where
we're
gonna
have
the
CEO
of
a
start-up
called
block
Phi
that
recently
raised
50
million
dollars
to
offer
loans
against
crypto
that
you
might
own.
C
C
C
A
Okay
and
thank
you
goatee
for
all
your
work
and
helping
to
make
this
come
together
very
much
appreciated
and
I
think
we
may
have
a
new
home
okay.
So
we
also
want
to
thank
Evan
'im
for
helping
to
sponsor
this
event.
I'll
talk
a
little
bit
about
Evernham
and
and
our
speaker,
Drummond
is
sitting
there
and
and
I
think
we
have,
and
who
is
our
other
Evernham
person
that
I
was
talking
to
oh
there.
Oh
that's!
This
is
Michael.
Okay,
we
hit
someone
else
here
who
was
I
talking
to
anyway.
A
A
The
first
open
source
distributed
ledger
network
dedicated
to
self
sovereign
identity,
works
with
leading
companies,
institution
institutions
and
NGOs
to
create
and
deploy
new
private
by
design
solutions
with
give
which
give
the
industry
true
control
and
ownership
of
their
personal
data,
and
that
obviously
flows
into
our
conversation
today
and,
of
course,
other
sponsor
is
Atlas
work
base
and
we've
heard
from
Kim.
So
thank
you
for
that.
Okay,
community
announcements
for
our
next
HCM
on-site
meeting.
A
We
we
have
some
potentials
and
I'm
currently
in
talks
with
t-mobile
we're
gonna
see
if
we
can
get
t-mobile
to
come
and
speak
on
in
theory
on
in
D,
some
of
the
work
that
they're
doing
within
D.
We
have
a
shout
out
right
now
to
IBM
to
see
if
we
can
get
IBM
folks
to
show
up
and
if
anyone
knows
local
IBM
folks,
let
me
know
I'm
working
with
Curt,
Wedgwood
I
think
if
anyone
knows
Kirk
and
Oracle
Corporation
contacted
us
to
see
if
they
can
have
someone
from
Oracle
come
and
speak
to
this
group.
A
A
Okay,
anyway
token
forum
dot-com,
if
you're
interested,
but
you
should
have
the
email
for
that
already
and
that's
happening
on
August
9th
blockchain
conference,
Seattle
2018,
hosted
by
FinTech
worldwide,
that's
August
21st
at
the
Washington
State
Convention
Center.
We
have
free
admission
free
general
admission
for
the
conference.
If
you
didn't
get
the
promo
code
come
find
me
that
went
out
in
the
email
blasts.
A
That's
blockchain,
Seattle,
comm
and
blockchain
Seattle
not
to
be
confused
with
watching
Conference
Seattle,
hosted
by
blockchain
Seattle
meetup,
which
is
sort
of
the
big
mothership
for
blockchain
generic
meetups.
That's
September,
10th
to
11th
at
the
Hyatt
Regency
Bellevue
HSM
members.
We
get
a
10%
discount
with
the
promo
code
and
then
blockchain
Seattle
dot.
Io
is
the
place
to
go.
If
you
want
to
learn
more
about
that,
does
all
that
sound
familiar.
A
Those
of
us
that
are
members
probably
got
a
bunch
of
emails
for
me
over
the
past
month
or
so
about
this
okay
onto
the
presentation,
so
Drummond
Reid
is
going
to
be
speaking
on
an
introduction,
disease
centralized
and
identity
and
hyper
ledger.
Indie,
and
most
of
us
here
should
know
about
a
hyper
ledger.
A
Indie
by
now
so
I
have
this
great
curricula,
so
Drummond's
just
sit
for
a
while,
because
this
is
gonna
take
what
ten
minutes,
maybe
so
we
are
so
honored
to
have
this
guy
and
I
feel
bad,
because
he's
sitting
right
here,
we're
just
gonna
make
as
he
go
get
huge.
This
guy
is
really
phenomenal,
so
I'm
gonna
read
through
this.
It's
amazing,
okay,
so
Drummond
Reid
has
spent
over
two
decades
in
Internet,
identity,
security,
privacy
and
Trust
frameworks.
A
He
joined
Evernham
as
chief
trust
officer
after
Emma
Evernham
acquired
respect
network
where
he
was
CEO
co-founder
and
co-author
of
the
respect,
trust
framework,
which
was
honored
with
a
privacy
award
at
the
2011
European
identity
conference,
identity,
yeah,
identity
conference
Drummond
is
also
a
trustee
and
secretary,
the
sovereign
foundation,
where
he
serves
as
chair
of
the
sovereign
trust
framework
working
group
he's
a
member
of
the
steering
committee
of
the
decentralized
identity
foundation
and
co-editor
of
the
D
ID
decentralized
identifier
specification
in
the
w3c
credentials.
Community
group.
A
He
served
as
co-chair
of
the
Oasis
xti
technical
Mideast
Technical
Committee
since
2004,
which
is
a
semantic
data
interchange
protocol
that
implements
privacy
by
design,
which
I
actually
know
about
a
XDI,
that's
old
stuff,
not
old,
old
bad
old
old,
as
in
legacy
been
around
for
a
while
prior
to
starting
respect.
Network
Drummond
was
executive
director
of
two
industry
foundations.
The
information
card
foundation
in
the
open
identity
exchange
he's
also
served
as
a
founding
board.
A
Member
of
the
open
ID
foundation
is
TPA,
which
is
an
internet
search,
internet
international
security,
trust
and
privacy,
Alliance,
the
ex-cia
org
organization
and
identity
Commons,
and
then
in
2002,
Drummond
received
the
digital
identity,
Pioneer
Award
from
digital
ID
world,
and
in
2013
he
was
cited
as
an
oasis,
distinguished
contributor,
wow
man
and
I
feel
bad.
Now.
My
days
are
not
like
this
so
anyway.
So
please
big
hand
to
drum
and
read
to
talk
on
hyper
ledger.
Id.
C
E
E
E
I'll
try
and
identify
one
I'm
going
to
wear
a
specific
hat
and
the
talk
I'm
going
to
give
on
today.
But
the
big
picture
questions
of
of
what's
going
on
here
and
and
what
I'm
going
to
talk
about,
we
find
it
really
helps
to
get
right
up
front
I
work
for
Evernham,
which
is
a
commercial
software
vendor.
You
know,
classic
you
know
out
there
for
profit
company
right,
Evernham
birth.
What
is
now
sovereign,
the
sovereign
foundation.
It
is
a
global,
it's
a
distributed
ledger
and
an
infrastructure
specifically
for
self
sovereign
identity.
E
That's
what
I'm
going
to
explain
here
today,
but
that's
a
non-profit
foundation
was
started
about
two
years
ago
and
it
has
its
own
staff
and
folks,
from
all
around
the
world,
I'm
happy
to
point
out
that
the
new
marketing
director
for
the
sovereign
foundation,
Helen
Garneau,
is
here
with
us
she's,
also
based
in
this
area.
Yeah.
E
So,
and
so
I
am
one
of
the
13
trustees
of
the
sovereign
foundation
and
we
have
another
trustee
here
with
us
today.
Mr.
Peter
Simpson
who's
ngoi
respond.
He
should
be
coming
and
giving
you
a
talk
about
the
very,
very
cool
stuff
that
he's
doing,
but
it's
the
self
sovereign
identity
portion
is
using
sovereign.
E
Neither
one
of
us
knowing
about
the
other
and
within
two
weeks
of
learning
about
the
other
and
getting
together,
we
decided
to
merge.
That's
whole
nother
story
happened,
tell
you
over
beer
sometime,
but
we
recognized
that
what
we
were
doing
had
to
become
a
global
public
utility.
When
you
hear
that
word
think
internet
think
domain
name
system,
those
are
global.
Public
utilities
right
they
work
for
everyone,
they're
open,
standards-based,
equal
access,
we
just,
but
we
depend
on
them
enormous,
Li
and
and
the
infrastructure
we
have
today
for
the
internet.
E
It's
got
a
lot
of
issues
with
trust
and
that's
why
we're
bullies
infrastructure
so
Evernham
donated
the
code
that
it
had
developed
for
the
ledger
and
the
early
code
for
ages,
2
sama
foundation
to
now
you
know
manage
as
a
public
trust
and
shortly
after
that,
I
want
to
give
huge
props
to
Linux,
Foundation
and
hi
pleasure
project
for
hiring
brian
behlendorf.
How
many
folks
here
have
ever
met
brian
and
talk
with
him
really
seriously
the
only
one
I
mean,
of
course,
you're
there,
but
anyway,
I
want
to
tell
you
they
made
a
brilliant
move.
E
There.
Brian
is
one
of
the
original
coders
and
founders.
The
Apache
project
that
you
know
runs
I.
Think
it's
like
70%,
you
know,
Apache
is
still
70%
of
the
web
servers
on
the
Internet,
but
it
wasn't
just
what
he
did
with
the
code
there.
In
the
early
days
of
the
web,
it
was
recognizing
how
open
source
projects
had
to
be
governed
and
managed
to
really
achieve
the
kind
of
scale
and
robustness
that
they
needed
to
run
the
web
and
to
be
secure,
and
all
these
things
Brian
helped
pioneer
those
practices
along
with
other.
E
You
know,
other
members
of
the
Apache
project
and
he's
gone
on
to
do
a
lot
of
fascinating
things
in
health
care
in
security,
interesting
enough
and
identity.
A
lot
of
people
don't
know
that,
and
it's
been
a
venture
capitalist.
It's
a
lot
of
fascinating
he's,
a
fantastic
guy,
super
high
integrity,
great
great
speaker
and
communicator
as
well,
and
all
sudden
we
find
out
he's
been
appointed
the
director
of
hyper
ledger
project,
which
was
pretty
cool
because
I
knew
the
venture
capital
gig.
He
was
in
I'm
like
wow.
E
That's
a
lot
to
pull
him
away
from
that,
but
that's
how
much
I
knew
that
he
believed
in
the
potential
of
blockchain
technology
an
open
source,
and
so
when
that
happened
we
said
well,
we
could
build
a
community
at
the
sovereign
foundation
around
the
open
source
for
hyper
light
for
sovereignty,
or
we
can
go
to
the
hyper
ledger.
Googlers
Foundation
talked
to
Brian
about
contributing
it
there.
E
He
told
us
right
up
front
and
we
talked
to
others.
We
said
ok
start
to
meet
the
folks.
There,
maybe
it'll
be
a
six-month
process.
It
was
six
weeks
until
the
technical
governance
board
of
the
hyper
ledger
voted.
Yes,
we
want
to
take
in
this
project
that
became
hyper
ledger.
Indie
and
I
just
had
a
question
an
email
list
earlier
today.
Why
didn't
we
just
call
hyper
laser
sovereign?
Well,
a
trademark
for
another
organization
can't
call
an
open
source
project
under
that
trademark,
so
you
have
to
come
up
with
your
own
non
trade
markable
name.
E
So
that's
why
this
code
base
is
called
hyper
ledger
indie
and
by
the
way
India
is
like
everything
else
there
are
patches
to
license.
Anybody
can
use
it
for
I'm
gonna,
explain
in
my
presentation
how
that
code
base
is
designated
by
this
foundation
to
be
run
by
the
stewards
of
that
foundation
to
run
the
network
and
an
extent
that
they
want
interoperability,
the
agents
they
run.
That
code
as
well.
Evernham
is
running
that
code.
You
know
whether
eventually
Microsoft
or
others
will
decide
to
run
that
code
to
write
their
own.
E
That's
up
to
them,
because
it's
all
open
standards,
space
as
well
so
I
just
want
to
make
sure
at
the
outset,
I'm
going
to
talk
I'm
not
going
to
talk
much
in
fact,
almost
at
all
about
ever
name,
I'm
going
to
talk
about
hyper,
ledger,
indie
and
and
what
all
this
is
about,
and
then
how
sovereigns
implementing
it
and
I
told
rich
upfront.
This
is
a
huge
subject:
area.
E
I've
given
three
me
two
other
talks
this
week
and
I
combined
a
bunch
of
things
here,
so
I
don't
want
to
go
on
here
for
a
half
an
hour
and
just
have
any
pile
up
questions
I'm
going
to
break
into
smaller,
smaller
chunks,
just
cover
some
stuff,
explain
it
and
then
you
know
ask
me
questions
right.
I
want
to
understand
how
this
is
relevant
to
what
you're
doing
can
I
just
ask
a
quick
question:
how
many
folks
here
are
actually
coders
or
contributors
and
working
directly
with
hyper
ledger
code
of
any
kind.
E
Okay,
so
it's
it's
more
of
a
business
facing
audience
or
applications
facing
it.
How
many
of
you
are
building
watching
applications
of
some
kind,
all
right,
more
hands
there?
How
many
of
you
are
more
in
the
business
side
is
just
figuring
out
how
this
is
a
new
new
business
area
for
you,
okay,
all
right
good!
We
got
a
mix
of
all
these
things.
All
right,
I
decided
to
bring
us
some
slides
on
Monday,
four
of
us
presented
I'd,
never
heard
of
the
conference
called
Pacific
Northwest
economic
region
conference
in
Spokane.
E
E
To
do
with
this,
they
literally
panels
all
got
together
and
say:
you're
going
first,
you
have
to
establish
right
up
front
that
we're
not
going
to
talk
about
cryptocurrency
right,
we're
gonna
talk
to
a
bunch
of
government,
folks
and
business
people
and
we're
gonna
say
no.
No,
no!
We're
gonna
talk
about
something.
That's
not
has
anything
to
do
with
that.
E
So
then
I
stuck
in
you
know
this
to
make
sure
they
were
all
comfortable
like
no
yeah
we're
not
going
to
talk
about
I
CEOs,
and
you
know
how
many
folks
this
room
would
or
cryptocurrency
and
blockchain
evangelist
there.
You
put
him
a
key
key.
Yes,
so
I
did
right
up
front
to
that
audience.
You
know
we're
presented
this
and
then
and
I
said.
Okay,
exactly
what
was
said
earlier
today.
Blockchain
Bitcoin
is
a
wonderful
example.
I
mean
the
reason
we're
all
in
this
room
is
Bitcoin
right.
We
wouldn't
have
done.
E
Maybe
etherium
would
have
happened
or
maybe
something
else
would
have
bought
it
out,
but
awareness
of
blockchain
technology
all
came
about
because
of
its
success
with
crypto
currencies
and
I'm.
Actually,
a
big
fan,
I'm,
not
a
deep
holder
but
I'm
a
big
fan-
and
you
know
that's
another
talk,
but
I
wanted
to
reassure
them
about
that
and
then
just
make
this
I
think
this
really
is
an
important
statement
and
it's
important
perspective
to
have
fundamentally
blockchain
solves
decentralized
trust
problems,
okay,
which
are
inherently
cybersecurity
privacy
problems.
E
This
is
the
big
you
know
this
is
a
big
AHA.
This
is
this
is
why
we're
here?
This
is
why
the
industry
gets
so
much
attention
is
why
crypto
currencies
ultimately
are
are
successful
because
they're
a
core
application
of
decentralized
trust
but
they're,
not
the
only
application,
decentralized
trust.
How
many
folks
have
seen
that
cartoon.
E
Did
you
know
it
is
the
most
reprinted
New
Yorker
cartoon
in
history
by
almost
double
any
other
one?
Does
that
give
you
a
sense
of
just
how
big
the
problems?
Internet
identity
is
seriously
when
we,
when
we
in
January
the
sovereign
foundation,
released
a
white
paper?
We
wanted
to
put
that
cartoon
on
the
first
paper.
We
got
in
touch
with
New
Yorker
and
they
were
like
you
and
everybody
else
so
seriously.
That's
how
the
problem
is
a
variant
on
that
kind.
I
mean
inspired
by
that
cartoon.
E
That's
the
logo
of
a
workshop
that
takes
place
at
the
Computer
History
Museum
and
Santa
in
Mountain
View
every
six
months
and
the
next
one
is
number
27.
So
do
the
math,
okay
13
years
of
roughly
200
experts
from
around
the
world
getting
together
just
to
solve
this
problem
of
internet
identity
and
the
relevance
you
know.
Why
did
hyper
lender
and
you
come
into
into
the
Hyperlight
your
family
so
fast,
because
blockchain
technology
by
itself
doesn't
solve
that
problem.
E
It
needs
identity
like
everything
else
and
I,
don't
know
how
many
folks
are
aware,
but
I'm
gonna
go
straight
to
the
point.
Ibm
was
that
you
know
one
of
the
largest
voices
and
founders
of
the
hyper
ledger
project
at
the.
If
the
Linux
Foundation
they
brought
in
fabric
they've,
been
sort
of
the
800-pound
gorilla,
we
weren't
sure
how
they
were
going
to
react
when
we
brought
in
when
we
proposed
to
bring
in
hyper
ledger
India
and
frankly,
they
were
sort
of
split.
E
You
know
there
are
folks,
like
we
got
IBM
technology
that
we
can
use
for
Identity
Management.
We
don't
need.
No,
you
know
none
of
this
new
decentralized
stuff,
but
there
were
others
that
were
more.
You
know
more
favorable,
basically,
those
voice
that
were
sure
to
shut
it
down
by
all
the
rest
of
the
members
who
were
like
yeah.
We
want
to
solve
that
problem
come
on
in
here
and
help
us
do
it
so.
E
Watching
needs
identity.
The
web
needs
identity.
The
Internet
is
always
needed
an
identity
some
way
the
sometimes
the
way
the
problem
is
put
is
the
internet
was
built
without
an
identity,
layer
and
I
submit
to
you
that,
with
watching
technology,
we
can
finally
deliver
that
identity,
layer
and
essentially
where
you
can
hear
today,
is
the
story
of
how
we're
going
to
do
that
and
it's
all
around.
You
know
the
code
base
at
high
plays
you're
Indian,
so
to
start
out
and
just
quickly
have
you
understand?
Why
is
why
do
with
this
watershed?
E
With
digital
identity
I'm
going
to
quickly
run
through
Timothy
ratha,
the
the
CEO
of
Evernham
came
up
this
very
simple
way
of
describing
it.
We've
been
through
three
generations:
three
phases
of
internet
identity,
the
first
one,
everyone
there's,
not
a
person
in
this
room
that
uses
the
internet
doesn't
recognize
this.
This
is
how
accounts.
This
is
how
you
do
digital
identity
on
the
Internet
today
you
are
this
wonderful
dotted
circle
and
you
have
your
identity
by
virtue
of
having
the
count,
someplace
a
website
and
application
and
network
you
name
it
right.
E
It's
a
dotted
circle
because,
as
soon
as
you
don't
have
that
account-
or
they
take
away
that
kind
of
way,
you're
gone,
you
don't
have
any
persistent
identity,
you
don't
have
any
identity,
you
alone,
control
on
the
Internet,
okay,
but
it
works.
This
is
how
you
know
we
built
localized
systems
and
we
started
connecting
them.
We
just
took
the
identity
model,
we
had
locally
and
we
just
said
hey.
If
you're
gonna
connect
to
everything
in
the
internet
then
go
get
an
account
every
place.
You
need
one
I'd
like
to
point
out.
E
It
actually
took
seven
years
of
work
just
to
develop
the
standards
needed
for
encrypted
connection,
so
we
could
do
that
securely
over
the
internet,
just
log
into
a
website
or
do
ecommerce
transactions
Avesta.
So
just
that
simple
first
step
took
a
lot
of
what
standards
were,
but
there
was
so
much
pain
there.
How
many
folks,
in
this
room
figure
you
have
more
than
100
usernames
and
passwords.
E
The
rest
of
you
didn't
put
your
hands
are
lying
or
you're,
not
keeping
track.
So
we
went.
We
said:
here's
how
we're
going
to
solve
it.
We're
gonna
put
a
new
service
provider
in
the
middle,
an
IDP,
an
identity
provider.
They
provide
you
with
your
identity,
which
really
means
you
have
one
account
with
them,
and
then
they
can
log
you
in
and
Kure
attributes
with
all
those
other
organizations
and
applications
that
are
bidding
that
needs
it
all
right.
E
A
lot
of
you
are
probably
using
self
SSO
single
sign-on
products
within
your
company
organization
right
on
the
internet,
you're
using
google
blogging
with
Google
Facebook.
You
know
Twitter
Linkedin,
that's
called
social
sign-on,
that's
just
IDP
writ
large.
Okay,
that's
done
now
the
protocols
for
doing
that,
whether
it's
internal
to
an
enterprise,
sword
internet
scale,
three
generations
over
15
years
worth
of
work.
A
lot
of
her
rich
talked
about
is
I,
just
sort
of
came
on
board
the
terrain
right
about
when
this
was
happening,
and
then
I've
lived
through
those
two
and
yeah
so
long.
E
It's
a
hard
problem
lot
of
warts
got
onto
it.
In
the
end
there
couple
problems
with
federated
identity.
First,
is
it
only
works
with
the
Federation
that
you
can
join?
You
know
each
IDP
only
has
Solarian
Federation.
You
can't
use
Facebook
to
log
into
your
bank.
Facebook
doesn't
offer
that
level
of
service
or
they
don't
have
the
connection
with
your
back.
Secondly,
it's
not
portable
all
the
relationships
you
set
up
use
if
you
use
a
Facebook
to
connect
to
a
hundred
organizations
and
then
you
leave
Facebook
or
they
cancel
your
account,
which
happens.
E
E
Please
explain
that
we're
not
talking
about
the
sovereign
citizen
movement-
and
you
know
I
just
you
know,
get
rid
of
government
and
everything
else
it's
funny,
but
the
term
I
didn't
actually
think
the
term
sell
sovereign
would
stick
when
it
first
came
out.
We
started
using
to
describe
this.
It
turns
out
it's
just
everyone's
calling
it
that
now
and
even
the
governments
that
were
uncomfortable
about
it
are
starting
to
go
alright.
E
Well,
that's
what
everyone's
gonna
call
it,
but
that's
where's
one
of
the
sevens-
and
you
know
don't
don't
forget
that
so
that
model
is
removes.
That
third
party
put
you
back
in
a
direct
relationship
which,
interestingly
enough,
you
don't
call
it
an
account
when
you
have
a
relationship
with
somebody
right,
I
wouldn't
take
my
business
card
in
a
head
and
appear
and
go
thanks
for
creating
an
account
with
me
right.
It's
it's
a
relationship
and
technically
we
call
it
a
connection
Oh.
What
like
a
tcp/ip
connection
between
two
notes,
right
peer-to-peer.
E
So
what
can
make
this
work?
Well,
the
hint
is
right
here,
but
actually,
how
does
the
blockchain
solve
that
problem?
Well,
point
one
has
nothing
to
do
with
cryptocurrency.
The
way
it
works
is
this
you
as
a
peer
and
now
I
get
to
my
favorite.
The
prop
portion
of
this
presentation,
just
I
got
a
hold
that
the
answer
to
decentralise
blockchain
based
identity
looks
like
this.
E
The
way
you
prove
your
identity,
the
real
world
today
is
with
this
device.
It's
wonderfully
decentralized,
because
any
credential
that
you
can
get
credential
from
any
issue
of
credentials
anywhere
in
the
world.
You
can
put
it
in
your
wallet.
You
can
go
to
any
any
place,
would
call
a
relying
party
or
verify
of
those
credentials
and
verify
it.
I'm
Washington,
a
citizen,
I,
went
and
got
my
driver's
license.
Put
it
in
my
wallet.
E
I
walked
to
the
airport
and
I
hand
it
to
TSA,
who
verifies
it
by
little
blacklight
little
checking
the
biometric
and
I'm
on
a
plane.
Okay,
that
is
it's.
You
know
it's
proven
to
work,
it's
secure
enough,
although
it
could
be
better
and
it's
totally
decentralized.
There's
no
single,
centralized
Authority
for
what
credentials
I
can
put
in
this
wallet
or
who
can
verify
them
so
essentially
the
whole
store
of
digital
identity
I
mean
a
self
sovereign
identity
is
how
we
take
this
and
get
out
the
other
hand,
and
we
put
it
on
this.
E
Okay,
now
all
of
you
in
this
room,
you
know
we
started
out
talking
about.
We
are
going
to
talk
about
a
wallet,
but
it's
not
a
cryptocurrency
wallet,
or
at
least
that's
not
the
primary
purpose
of
this
kind
of
wallet.
That's
why
we
call
it
an
identity
wallet.
It's
ironic,
the
only
good
graphic
I
can
find
in
short
period,
has
credit
cards
in
it,
but
think
identity,
wallet.
Okay,
now
I'll
put
these
props
down
because
I'm
going
to
need
them
again.
E
Okay,
so
you
got
this
wallet,
you
can
put
your
own
credentials
in
it,
just
like
a
good
print,
a
business
card
and
put
it
in
that
wallet,
but
is
that
actually
gonna
work?
It's
not
good.
I'm,
not
gonna,
be
able
to
go
to
TSA
and
give
them
a
business
card
out
of
my
digital
wall
and
see.
That's
me
right.
So
what
are
you
gonna?
E
Get
those
credentials
that
they're
going
to
trust
well,
where
do
I
get
and
credentialing
that
they
would
trust
it
in
go
the
Washington
State
driver's
license
Authority,
which
is
it
a
peer
I'm
going
to
go
over
there
I'm
going
to
do
the
same
thing.
I
do
digitally
that
I
do
physically,
which
is
prove
my
identity,
to
the
point
where
they
say
yes,
they're
going
to
give
me
that
credential
and
it's
going
to
you
know
literally
it's
going
to
be
downloaded
into
my
digital
wallet.
E
E
What
makes
those
credentials
believable
is
that
the
credential
needs
to
be
signed,
digitally
signed
by
that
peer,
so
that,
when
it's
shown
to
another
peer,
they
can
verify
the
signature
and
I
countersign
it
before
I
give
it
so
that
the
verifier
is
actually
able
to
check
both
the
issuer
and
the
veteran
and
the
holder
of
the
credential
are
valid.
The
problem
the
blockchain
solves
is:
it
gives
us
a
decentralized
key
management,
this
way
to
discover
and
verify
those
keys
which,
if
you're
in
the
blockchain
technology
much
everything
in
blockchain,
is
built
on
crypto
right.
E
It's
also
so
using
a
blockchain
just
to
actually
store
the
keys
and
look
them
up.
It
seems
like
a
trivial
usage.
It
just
solves
one
of
the
biggest
and
oldest
problems
in
PKI
and
cyber
security
on
the
planet.
So
it's
not.
This
is
not
a
complex
blockchain.
You
know
I.
If
we
want
to
dive
into
consensus,
algorithms
and
everything
else.
This
is
relatively
simple:
it's
it's
optimized
to
be
pretty
fast
and
when
we
brought
it
into
to
hyper
ledger,
for
instance,
they
they
said.
Well,
you
got
a
pretty.
You
know
fast
performing
block.
It's
like!
E
E
D
E
A
great
question
and
the
answer
is
I'm.
Sorry,
the
question
is,
how
do
you
choose
which
peers
can
assign
which
credentials
for
whom?
Okay
and
I
want
to
I
want
to
reinforce
the
nature
of
that
question?
Is
that
oh
well,
there's
someone
who's
going
to
dictate
that
to
you
and
that's
the
nature
of
centralized
systems
or
what
we
call
administrative
identity
in
a
decentralized
world?
The
answer
is
nobody.
Does
that
just
like
nobody
does
it
here
who
dictates
you
what
credentials
I
have
to
go
in
your
wallet.
E
E
So
those
three
rules
of
issue
or
holder
and
verifier-
it's
not
very
well
shown
up
to
this
diagram.
Whoever's
going
to
issue
the
the
credential
has
to
be
a
part
of
era.
Fires
are
going
to
trust,
so
the
TSA
says
you
know
I'm
going
to
trust
driver's
license
authorities
for
50,
US
states
or
passports
right.
They
that's.
Their
policy
is
verifier.
The
issuers
turn
around
and
go
okay,
I'm
only
going
to
issue
credentials
to
Washington
State
citizens
for
a
driver's
license
or
passport
authorities
go
ahead.
D
E
Okay,
I
think
I.
Think
we've
got
to
misunderstand
about
the
the
the
trust
networks
being
created
here.
Anyone
can
issue
credentials,
anyone
can
hold
them.
Anyone
can
verify
them
who
the
trust
networks
that
form
around
doing
that
are
independent
of
the
underlying
technology.
It's
just
like
you
can
create
a
website
and
you
can
decide
to
browse
it
and
no
one
is
controlling
your
movement,
but
it's
all
using
the
Internet.
Does
that
make
sense
I'm
going
to
get
deeper
into
verifiable
credentials
as
we
go
through
this
and
I
think
it
will
become.
E
It
will
become
more
clear
all
right,
but
to
quickly
just
explain
that
this
will.
This
is
the
whole
model
for
self
serving
identity,
and
it
depends
on
for
emerging
open
standards
and
the
first
and
I'm
gonna
explain
each
of
the
four
of
them.
In
my
presentation,
the
first
ones
called
decentralized
identifiers,
and
that
is
the
standard
for
how
you
put
a
public
key
on
a
blockchain
with
it.
E
You
can
actually
rotate
the
keys
over
time
to
persistent
address
or
a
public
key
on
a
blockchain,
and
it's
it
is
that
literally
the
base
layer
of
the
whole
thing.
Second,
one
is:
how
can
we
have
interoperable
digital
wallets
for
the
key
need
for
these
addresses?
Third,
one
is:
how
do
we
now
do
peer-to-peer
authentication
to
graphically
protected?
We
call
it
did
off
and
it
is
fundamentally
finally,
the
username
password
killer
for
the
internet.
E
Anyone
in
this
room
have
kids,
so
what
you
can
do
is
go
home
and
tell
them
I
finally
heard
how
we're
going
to
get
rid
of
usernames
passwords
for
your
generation,
when
we
would
be
told
that
the
Pacific
Northwest,
that
kind
of
a
region
audience
we've
got
a
standing
ovation
and
the
last
one
is
the
credentials
themselves
for
these
to
work.
It's
very
easy
for
pieces
of
plastic
to
fit
in
the
wallet
for
these
to
work.
They
have
to
be
in
a
digital
format,
with
the
signature
that
everyone
can
recognize.
E
That
is
the
critical
piece
and
the
good
news
there.
That's
a
w3c
working
group
that
is
two-thirds
of
the
way
through
its
Charter,
and
so
the
standard
should
be
out
next
year
and
we're
obviously
building
software
for
right
now,
so
those
four
standards
I'll
just
quickly,
listen
to
them.
So
the
idea
is
at
w3c.
Dkms,
which
I
was
a
principal
investigator
for,
is
actually
department
homeland
security
here
in
the
US,
the
Commission,
the
work
to
develop
that
architecture,
that's
more
like
tentacle
to
Isis,
did
off
is
already
under.
E
It's
called
the
decentralized
identity
Foundation,
which
is
industry
consortium
will
probably
go
to
ITF
and
lasting
verifiable
credentials
at
w3c.
By
the
way,
this
is
anyone
who
wants
it.
Just
give
me
your
card
at
the
end
of
this
I'll.
Send
you
a
copy
of
this
presentation.
It's
all
all
wide
open
and
stuff.
It's
probably
out
there
listed
someplace,
alright,
so
I'm
going
to
stop
for
a
second
and
just
go.
That's
a
very
big
picture
about
Self
Serve,
an
identity
and
now
I'm
going
to
drill
down
into
a
couple
areas
of
that.
E
D
E
Again,
I'm
gonna
hold
this
up
as
the
example
both
models
work,
in
other
words
you
can
have
in
terms
of
the
credentials
and
and
let's
just
call
the
community
of
issuers
holders
and
verifiers
of
those
credentials.
They
can
be
as
centralized-
and
you
know,
top-down
addicted,
like
say
ad,
in
India
right
where
everyone
in
the
country
needs
to
get
biometric
identity,
actually
don't
get
a
credential
yet
but
they're
now,
considering
it
all
the
way
over
to
the
other
end
of
the
spectrum.
E
E
We're
actually
publishing
paper
at
the
sovereign
foundation
right
now
and
the
Trust's
our
working
group
explaining
that
spectrum
and
talking
about
each
of
the
things
in
what's
called
the
web
of
trust
model
that
you
can
add
to
make
it
larger
and
more
scalable
and
and
it
basically
more
formal,
but
the
infrastructure
allows
for
everything,
so
it
can
be
as
peer-to-peer
as
possible
or
it
can.
You
can
add
hierarchy
and
add,
add
rules
and
trust
room
works.
Is
that
helped
answer
your
question
got
it
good?
Oh.
E
That
is
a
super
good
question.
I'm
gonna
give
you
an
answer
right
now,
but
then
you're
gonna
want
to
see
what
I'm,
what
I'm
going
to
explain
coming
up
credentials.
Don't
go
on
the
blockchain
you
on
the
public,
blockchain,
okay,
they're
all
exchanged
peer-to-peer,
so
it's
basically
comes
down
to
the
capacity
of
a
wallet
for
you
as
an
individual
or
the
capacity
of
issuer
to
issue
credentials.
And
since
you
can
have
issuers
everyplace
wallets
everyplace,
it's
like
asking
well
how?
How
fast
can
the
cloud
go.
E
Nope,
no,
no,
no
exactly
the
opposite.
To
be
specific.
If
I
take
a
digital
wallet
here
on
this
device,
okay,
credential
I'm,
not
its
couple
K,
okay,
you're
running
a
website-
and
you
say
you
know
I
need
to
know
if
you're
Washington,
State
citizen
and
one
of
the
credentials
all
except
for
that
is
a
watch
to
take
driver's
license
right.
I
get
I
get
the
driver's
license
from
the
from
the
you
know
why
she's
a
DMV
they
get
a
D
ID
on
the
blockchain.
They
issued
me
a
driver's
license!
Sign
it
with
that.
D
D
E
Think
I've
even
less
than
not
because
in
fact
we're
talking
to
the
drivers
license
authorities
right
now,
because
all
that
bar
needs
is
a
piece
of
software
that
is
able
to
reference
50,
D
IDs
for
the
50
DMV.
You
know
issuing
companies
out
there,
it
can
cache.
Those
did.
Documents
are
about
to
talk
about,
or
it
can
just
look
them
up
in
real
time
on
the
chain
and
verify
so
it's
yeah.
The
idea
is
it's
about
as
lightweight
as
payment
systems,
for
instance
yeah
yeah,
exactly
very
similar
to
that
go
ahead.
E
Yes,
all
things
are
possible.
I'm,
going
to
talk
about
zkp
coming
up
shortly.
The
sovereign
protocol
for
exchange
of
credentials
is
the
first
open
protocol
that
is
zkp
by
design.
It's
it's
it's
built-in,
it's
the
default,
whether
that
can
all
be
added
up
to
solve
that
problem
of
KY,
CML,
ATF
and
terrorist
financing.
There's
a
workgroup
forming
the
sovereign
foundation
to
work
on
that
because
it's
a
hard
problem.
But,
yes,
we
really
believe
in
you
know
doing
it
the
right
way
and
providing
every
citizen
not
just
with
encryption
but
with
zero
knowledge.
Encryption.
E
Yeah,
it's
self
serving
identity,
there's
no
such
thing
as
anything,
but
opt-in,
self,
sovereign
means
you're
in
control
of
this
wallet
self
sovereign.
Because
no
one
forces
me
to
have
credentials.
You
know
put
some
in
it
or
forcibly
takes
them
out
unless
I'm
in
a
dictatorship,
and
that
can
you
know
it's
a
harder
problem,
so
yeah
the
whole
idea
is
self
sovereign
identity.
Is
you
control
what
credentials
you
accept?
What
credentials
you
issue?
What
credentials
you
hold
yeah
I
know.
E
It
sounds
by
the
way
this
if
you
sense
tension
around
that,
it's
very,
very
common
because
separate
identity,
something
that
really
can
span.
We
talk
to
governments
about
it
on
one
side
and
there
are
some
governments
in
very
progressive
about
this
in
the
world.
Austria
Finland,
Sweden,
Canada
I
want
to
tell
you
and
their
other
governments
at
the
other
end
that
don't
want.
You
know
the
practically
won't.
Let
you
in
the
borders,
if
you're,
going
to
talk
about
subjects
like
that
right.
E
So
it's
not
that
different
than
cryptocurrency,
okay
I'll
keep
going
because
I
think
some
of
these
questions
will
get
answered.
We
could
be
able
to
go
deeper
and
deeper,
but
I'm
going
to
go
a
little
bit
faster,
because
these
are
more
more
storyboards,
so
you
want
to
have
my
digital
identity.
One
of
the
easiest
ways
to
understand
how
it
shifts
is
to
look
at
well.
How
old
does
identity
work?
You
know
in
the
world
today
most
of
you
are
from
the
US
right.
E
You
probably
recognize
that
a
Social
Security
number-
it's
not
mine
and
I-
didn't
get
it
from
Equifax,
but
but
there's
a
great
story
on
Wikipedia,
which
is
where
I
did
get
it
about
the
fact
that
40,000
people
use
have
used
this
Social
Security
number.
It
was
printed
on
a
little
insert
in
a
wallet
the
would
that
wouldn't
Woolrich
sold
back
on
the
Depression
era
to
prove
that
hey,
there's
gonna
wallet
with
one
of
these
little
plastic
windows
in
here.
E
So
you
don't
have
take
the
Crenshaw
and
they
stuck
a
little
one-third
size,
Social
Security
card
in
there
and
the
president
war,
which
had
his
secretary,
put
her
social
security
number
on
there,
so
it
yeah
so
people
run
a
wallet,
has
Social
Security
card
in
it
and
just
started
using
as
their
social
security
number
point
being.
Nobody
there's
no
way
to
prove
that
a
social
security
number
is
yours
all
by
itself,
right
and
interesting
enough.
Well,
this
is
this
is
being
recorded
right.
E
So
why
is
this
identifier
so
much
more
powerful
she's,
certainly
not
as
memorable,
but
the
reason
is
it's
the
address
of
a
public
key
on
a
block
chaining
and
it
really
mean
a
blockchain,
because
this
standard
called
the
IDS
is
written
for
any
blockchain,
that
you
can
write
a
D,
ID
method
for
and
I
got
a
list
coming
up
here,
but
pretty
much
any
monitor.
Blotching
can
support
the
ids
and
of
course
you
hold
the
private
key
right.
E
This
is
the
very
very
essence:
DNA
and
self
sovereign
identity
and
I'm
going
to
get
to
the
fact.
This
is
what
the
hypogeum
unicode
base
is
all
written
around
the
wallets
and
the
agents
and
the
nodes
that
do
this
stuff.
This
one
is
actually
a
sovereign
BIDU
because
you
can
have
different
forms,
but
the
only
requirement
is
this
global,
unique,
it's
cryptographically,
verifiable
and
you
can
go
look
it
up
on
the
ledger
and
get
back
this
thing
called
it
did
document.
E
So
you
can
look
at
that
and
I
think
it
should
be
patently
obvious
unless
we've
got
a
memory
person
here
in
the
room
that
you're
not
going
to.
Remember
any
of
that
right,
you
might
remember
the
D
ID,
let
alone
you
know
the
private
key
public
or
private
key
right,
so
how
you
gonna
manage
of
those
things
well,
I
can
manage
it.
The
way
most
of
us
even
manage
our
phone
numbers
today,
right
I,
probably
remember
about
three
or
four
phone
numbers
today,
but
I
have
probably
a
thousand
people
in
my
contact
book.
E
I
use,
you
know
computers
to
do
it,
so
that's
how
we're
going
to
do
it,
but
now
I'll
highlight
the
second
thing:
that's
different
right
in
the
US.
You
can
have
exactly
one
social
security
number.
If
you
have
more
than
one
your
there's
a
problem,
you're
breaking
the
law,
okay,
but
the
IDS
you
will
not
have
just
one.
You
will
have
thousands
of
them
and
that's
because
you're
going
to
have
one
per
relationship.
E
Every
electronic
business
card
I
hand
out
if
I
was
sitting
in
with
a
phone
and
an
and
a
QR
code
on
it.
It's
unique,
D,
ID
I
generate
them,
because
it's
the
address
of
a
key
pair
that
I
generated
in
order
to
generate
the
D
ID
and,
very
importantly,
so
what
watching
is
it
registered
on?
It
depends
on
how
broad
that
relationship
is
if
it's
one-to-one
never
hits
the
sovereign
public
blockchain.
E
It
goes
on
what
we
call
micro,
Ledger's,
just
shared
between
your
two
agents
or
if
it's
a
larger
community,
it
might
be
a
group
ledger,
it
might
be
a
private
ledger
or
if
it's
public
and
I
want
to
have
something.
That's
I've
got
a
blog.
I
want
to
be
able
to.
You
know,
make
assertions
from
then
it's
on
the
public
ledger,
but
everything
in
between
is
supported.
E
So
that's
so
so
so
again,
you're
going
to
have
thousands
of
them
and
because
it's
the
address
of
a
public
key-
and
it's
also
the
address
of
an
endpoint
for
an
agent
you
can
interact
with
every
D
ID.
You
have
gives
you
a
lifetime
encrypted
private
channel
with
whoever
is
the
other
end
of
that
relationship.
Another
person,
an
organization,
a
connected
thing,
good.
E
Yes,
they
create
the
key
pair
and
give
you
the
D
ID
that
lets.
You
always
verify
the
public
key
and
vice
versa.
It
was
precisely
that
characteristic
of
take
PKI
that,
as
we
know
it
today,
but
now
have
a
decentralized
way
to
register
or
verify
the
public
keys.
It's
a
reason
that
DHS
gave
my
company
respect
network,
for
we
were
bought
a
contract
to
say
how
do
we
do
that
and
do
privacy
respecting
identity
management
on
the
blockchain
they
paid
for
and
I
should
go
into.
E
E
Well,
when
you
used
it
off
to
send
a
sign
message
between
the
two:
yes,
exactly
yeah,
exactly
that
is
did
off
now
that
channel
we've
created
that's
what
we
often
call
it.
A
private
channel
is
also
the
perfect
mechanism
for
us
to
now
exchange
those
verifiable
digital
credentials.
So
the
D
IDs
by
themselves
are
like
IP
addresses
they
don't
confer
necessarily
any
trust
all
by
themselves.
You
build
that
trust
by
now
exchanging
those
credentials
right.
Think
of
it
in
the
human
terms.
The
D
ID
is
that
we
shake
hands.
E
We
met
each
other,
we
have
a
channel
now
with
each
other.
We
show
each
other
credentials
and
that's
how
we
start
to
build
up
trust.
What
we
talk,
of
course,
so
so
that's
how
they
can
do
that,
and
all
of
this
everything
I've
just
described,
does
not
require
any
centralized
registration
authority.
Okay,
you
register
the
D
IDs.
You
want
on
the
blockchain
of
your
choice
and
I've
got
a
list
of
them
coming
up,
but
basically
everything
out
there
Bitcoin
aetherium
various
one.
E
There
has
never
been
one
of
these
puppies
in
history.
This
is
about
you
know
it's
the
it.
The
spec
is
now
at
the
w3c.
It's
an
credentials.
Community
group
I'm
the
co-editor
of
the
spec,
but
Microsoft
and
IBM
to
come
out
publicly
and
said
we're
building
this
we're
supporting
it.
It's
becoming
an
official
w3c
working
group.
It's
the
first
identifier
spec
since
HTTP
URI
is
that
Tim
berners-lee
has
said
this
makes
sense.
E
He
hates
new
identified
new
types
of
identifiers
and
actively
works
against
them
until
this
one
came
along
because
he's
working
on
decentralized
identity
and
social
networking,
so
I
just
want
to
make
that
point.
I
don't
know
if
there's
any
folks
that
are
deep
into
identifiers,
but
but
that's
this
is
the
foundation
of
self
sovereign
identity.
The
entire
typology
journey
code
base
the
ledger:
the
agents,
the
wallets
all
based
on
the
IDs.
Okay,
I,
stop
there
questions.
E
So
I
first
I
have
to
laugh
because
you're
not
the
first
one,
to
bring
this
up
and
I
think
wow.
Now
that
we're
talking
about
globally
distributed
blockchains
being
centralized
we're
making
progress,
decentralization
is
really
happening.
So
first
you
choose
your
blockchain
but
to
the
extent
that
it
is
truly
decentralized
and
of
course
you
can
have
all
the
things
about
Bitcoin
mining
pools
and
everything
else.
It's
at
least
that
decentralized
as
in
you
know,
you're
not
tied
to
any
node
there.
And
so
you
know
it's
your
confidence
in
the
blockchain.
E
That's
why
we're
doing
the
sovereign
blockchain
in
a
specific
way,
so
that
governments
and
banks
and
healthcare
providers
can
all
you
know,
trust
it,
but
the
other
point
that
I
haven't
really
gotten
to,
but
I
want
to
reinforce
again
your
first
of
all
personal
pairwise
dids,
don't
go
on
that
block
Jen!
They
go
in
the
micro
ledger,
manage
between
your
two
agents.
No
one
needs
to
know
those
D
IDs
except
you
and
the
other
party.
That's
a
default
in
the
sovereign
ecosystem.
So
that's
that's
the
point.
E
Is
you
don't
don't
put
anything
more
on
the
sovereign
blockchain
and
the
next
one
is
zero
credentials
of
any
kind
go
on
the
blockchain.
Those
are
always
exchanged
peer-to-peer.
Even
if
an
organization
has
a
public
block
to
a
public
key
ID
like
that
Motor
Vehicles,
the
driver's
license.
That
issue
goes
directly
from
their
agent
to
your
agent.
The
blockchain
doesn't
know
about
it.
Nobody
knows
about
it.
It's
private
to
your
wallet
that
makes
sense.
E
Believe
me,
if,
if
folks
are
feeling
like
wait,
a
minute
I'm,
not
canvassing
it
Kansas
anymore,
that's
why
I'm
here
to
talk
to
you
about
this
is
this
is
a
paradigm
shift
in
sin?
You
know
in
in
digital
identity,
go
ahead,
oh
that
one's
coming
up.
You
get
the
prize
for
for
being
the
first
one
to
ask
it,
but
I've
never
given
a
talk
and
not
had
the
question
come
up,
you
know,
especially
you
hold
this
up
and
go.
This
is
gonna,
be
my
digital
wallet.
Every
parent's
it's
earn
goes!
Oh
and
my
child.
E
You
know
what's
gonna
happen
right.
Yes,
so
recovery,
absolutely
critically
important,
in
fact
that
the
second
contract
we
did
for
DHS
on
chemo,
but
that
was
the
number
one
problem
they
said
go.
You
know,
explain
how
you're
gonna
solve
the
problem
of
key
recovery,
the
wallet
recovery,
because
their
goal
just
to
be
clear.
E
If
this
is
going
to
change
our
cybersecurity
infrastructure-
and
you
know
and
solve
a
bunch
of
the
problems,
whether
it's
data
breaches
or
identity
theft-
you
know
nationwide,
we,
you
have
to
be
able
to
use
this
infrastructure
I'm
talking
about
exactly
like
use,
email,
a
client
or
a
browser
or
text
messaging
right.
It's
got
to
be
that
simple,
and
it's
got
to
be
that
that's
strong.
D
E
We
think
it's
large
enough,
yes,
yeah
the
space.
The
space
is
large.
Enough.
I
happened
to
be
an
identifier
geek,
so
I
love
talking
about
that.
You
know
what
the
PI
for
a
long
time,
because
I'm
not
actually
a
coder
I,
was
like
wait
a
minute.
It
just
keep
you
right,
you
got
128
bits
and
it's
always
gonna
be
unique.
Well,
of
course,
there
is
a
small
128
bits
by
the
ways
a
grid,
a
universally
unique
identifier.
Then
the
machine
generates
if
it's
128
bits
long.
That's
the
standard.
E
Itf
came
up
with
the
chance
of
collision
with
another
generated.
Uid
is
about
this.
You
know
the
chances
of
the
Sun
blowing
up
or
something
like
that.
In
other
words,
it's
possible,
but
so
minuscule
that
you
can
rely
on
it
and
I'm
like
yeah.
But
how
long
can
you
light
it
off?
Everyone
starts
doing
that
in
in
the
next
hundred
years,
and
it
turns
out
the
math
is.
If
everything
does
it
constantly
every
person
on
the
planet
for
like
the
next
century,
that
the
chances
of
a
single
collision
start
to
approach
something
that
might
happen.
E
But
again
we
would
want
to
do
that
I'm
being
told
by
folks
like
DHS,
that
they're
not
looking
at
any
of
the
crypto
involved
of
any
of
this
as
having
more
than
like
a
twenty
year
lifetime,
in
other
words,
we're
all
hot
planning
for
quantum
computing
and
in
quantum
cryptography
and
and
they've
got
whole
teams
that
are
planning
on
it
right
now,
so
we
had
to
as
part
of
the
DI
D
spectrum
I
talked
about
in
a
minute
we
had
to
turn
around
say.
Well,
what
is
the
if
you
have
public
keys
on
the
blockchain?
E
E
It's
a
very
good
question:
remember,
there's
think
of
it
as
two
layers
of
the
network,
there's
the
public
blockchain
and
then
there's
the
agents
and
all
the
micro
Ledger's
and
everything
they're
offering
the
only
common.
The
hyper
ledger
in
decode
for
the
sovereign
network
is
run
by
a
set
of
the
the
we
call
them
stewards.
They
run
the
nodes
and
it's
built
into
the
indie
software.
How
upgrades
are
pushed
out.
E
Right
so
here
I'll
be
very,
very
specific
about
the
hats:
okay,
I'm
wearing
the
hyper
ledger
in
the
code
allows
whoever
builds
the
network
the
blockchain
with
that
to
decide
that
it's,
not
it's
not
hard-coded
into
the
code.
So
it's
policy
about
what
you
do.
The
sovereign
foundation
decided
on
a
model
of
what
are
called
stewards
to
run
that
code
and
stewards
are
actually
vetted
by
the
foundation.
So
there
are
it's
in
the
mid
40s
right
now.
I
think
we
just
approved
two
more.
So
it's
about
forty
four
stewards
and
that
number
is
growing.
E
Anyone
can
come
to
the
foundation,
say
yep.
You
know
my
organization
anywhere
in
the
world.
In
fact,
the
requirement
is
that
have
to
be
diffused
around
the
world,
can't
be
too
many
in
any
one
jurisdiction,
any
one
cloud
hosting
Center
and
he
want
operating
system.
They
just
have
to
be
diverse.
It's
if
we
caught
decentralization
by
design.
All
those
stewards
must
run
the
hyper
ledger
in
decode
open
for
community
inspection
approved
by
the
foundation
each
of
the
upgrades.
So
if
there
is
governance
over
the
decentralized
system.
E
Yeah,
yes,
it's
actually,
ironically,
it's
the
hyper
ledger,
indie
community
that
produces
the
update
and
then
the
foundation
says
yeah.
You
know
we're
good,
but
we're
actually
trying
to
grow
the
community
so
that
there's
multiple
voices
out
there,
governments,
you
know
healthcare
providers,
financial
service
providers,
all
of
them
were
looking
and
saying,
yeah
we're
confident
in
the
next
upgrade.
Now
it's
just
of
the
of
the
of
the
the
blockchain
code.
Right,
all
that's
doing
is
storing
the
D
IDs.
E
E
E
The
answer
right
now
is
no
and
the
sovereign
foundation
approach
and
I'm
gonna
say
we
published
a
white
paper
January
and
says
we
get
it.
Yes,
we
need
an
incentive
system
within
the
network.
There
will
be
a
token
hasn't
been
announced
yet
or
anything
else,
but
the
sovereign
Federation
policy
is
there's
no
profit.
You
can't
make
any
profit
as
a
Stuart.
You
can
be
reimbursed
for
your
cost
of
running
and
done
so.
In
other
words,
it's
not
mining
based
and
it's
not.
E
E
Okay,
again,
I
don't
want
to
go
fairly
quickly
through
this
because
we're
going
deep
into
some
stuff
and
we
don't
have
a
deeply
technical
audience
I.
Just
explaining
these
di
DS,
they
were
actually
based
on
an
older
form
of
persistent
identifiers
in
the
Internet.
This
part
is
where
it's
called
the
D
ID
method.
You
create
one
for
a
particular
blockchain.
There's
a
group
that's
created,
what's
called
BD
CR
for
Bitcoin,
there's
two
of
them
have
been
developed
for
aetherium
I.
Think
there's
a
third
one
coming
I
think
I
actually
got
a
list.
E
Oh
here
it
is.
These
are
the
six
in
most
active
development
right
now,
the
ID
methods
and,
if
you're
interested
in
any
one
of
these
I
got
a
set
of
links
and
I
can
put
you
in
touch
directly
with
the
the
heads
of
each
of
these
projects.
The
only
one
that's
really
active
at
hyper
ledger
in
D
is
sovereign,
but
you
port
is
potentially
bringing
some
of
their
code
there.
This
is
another
whole
network
by
the
way,
verse
one.
It's
the
second
network
that
is
blockchain.
E
It's
permissionless,
that's
just
designed
to
do
self
settlement
identity,
so
you
have
sovereign
and
very
the
first
to
City
we're
just
solving
that
problem
global
network.
They
both
have
governance
organizations
all
that
stuff.
How
many
folks
are
familiar
with
box
tack,
yeah
they've
got
a
di
D
method
and
interesting.
Even
IPV
I
pee
fs
has
developed
their
own
di
D
method
for
a
very
sort
of
specialized
use.
E
All
right.
Let's
see
this
is
very
quick
stuff
about
the
fact
that
what
makes
it
be
any
work
is
it's
just
the
address
really
of
the
little
JSON
document
on
the
ledger
and
that
JSON
document
has
has
a
D
ID
itself
inside
of
it.
So
self-describing
has
the
public
keys.
That's
that's.
The
discovery
part
has
the
auth
protocol
that
says
hey
this.
This
D
ID
the
agent
for
this
D
ID
speaks
this
off
protocol.
If
you
want
to
verify
against
it
and,
lastly,
the
endpoints
for
how
do
I
interact
with
this.
E
If
it's
a
person,
if
it's
an
organization,
if
it's
a
thing,
okay,
when
DHS
asked
us
to
create
the
DKMS
system,
one
of
the
things
that
water
does
show
us.
How
I
will
use
this?
My
D
IDs
and
DKMS
wallet
to
connect
with
my
car
and
unlock
it
and
start
it
all
cryptographically
standardized
in
a
way.
That's
not
vendor
specific
right
and
I'd
love
to
point
out
the
parents
in
the
audience.
E
That
means
you
could
give
your
child
the
car
keys
and
constrain
the
hours
in
which
they
can
actually
use
the
car
and
do
other
interesting,
potentially
even
smart
contract
things
all
right.
So
that's
that's
as
deep
as
I'm
going
to
go
that
subject
now.
Let's
talk
about
the
keys
and
the
key
management,
because
a
second
point
I
make
here
is
regardless
of
what
you're
doing
in
watching.
Well,
there's
cryptocurrency
or
its
supply
chain
or
anything
else.
E
All
blockchain
depends
on
key
management
right
I
know,
because
even
though
I'm
not
deep
in
the
cryptocurrency
space,
the
different
folks
out
there
working
on
the
cryptocurrency
and
starting
to
know
the
bank's
the
credit
unions
and
governments
that
are
all
figuring
out,
what
do
we
do
about
this
key
management?
Is
one
of
the
main
areas
are
focused?
How
do
you
do
custodianship?
How
do
you
do
the
same
things
that
finance
the
service
providers
have
done
for
a
long
time,
they're
learning
from
the
cryptocurrency
community?
E
What
they're
realizing
is
man
keepin?
So
it's
really
hard
and
it's
really
important
so
for
self
suffering
identity.
You
have
to
be
software
for
your
keys
or
it's
not
self
sovereign.
So
that's
why
DHS
funded
this
work
applies
to.
It
applies
both
to
the
wallets,
where
you
gonna,
store
things
into
the
agents
that
it'll
exchange
them
and
the
whole
idea
is
come
up
with
a
standard.
So
you
can't
be
locked
into
a
particular
wallet
right.
I
mean
I
love.
E
This
device
and
I
have
sort
of
love-hate
relationship
with
Apple
I'll
be
public
about
it,
because
I
can't
just
move
from
this
device
to
a
Samsung
phone
or
another
device
without
losing
a
lot
of
functionality.
That
is
proprietary
to
Apple.
Well,
a
lot
of
things
I'm
willing
to
live
with
that.
But
if
you're
talking
about
my
keys,
my
identity,
my
money
I,
don't
want
that
locked
up
by
anybody
right.
E
This
tid
layer
of
the
blockchains
is
the
thinnest
piece
of
the
whole
thing
and
what
makes
it
all
work
are
these
two
layers
of
agents
and
wallet
so
can
I,
make
it
specific
up
there
and
we,
the
reason
or
two
is
edge
agents.
Edged
wallets,
lived
on
the
edge
with
your
devices
under
your
control.
You
have
the
computing
environment,
everything
else.
Okay,
cloudy,
gents
and
cloud
wallets
live
in
the
cloud.
That's
why
we
call
them
that
every
identity
owner
can
choose
what
configuration
they
want,
meaning
you
don't
have
them
you
you
if
you
trusted.
E
If
you
ran
your
own
cloud
or
you
trust
your
cloud
provider,
you
can
manage
everything
there
and
the
other
way.
If
you,
if
you
only
wanted
one
edge,
it's
not
trust
anything
in
the
cloud.
You
could
do
that
as
well.
That's
why
we're
showing
it
can
be
peer
to
peer
connections
either
either
here
or
here.
If
you
want
to
take
advantage
of
the
whole
stack,
there's
a
bunch
of
things
that
your
cloud
agents
can
do
for
your
edge
agents,
one
of
them
I'm
going
to
cover
in
a
minute,
is
backup
and
recovery.
E
E
E
Absolutely
so,
with
some
sovereign
identity
we
knew
from
the
very
outset
of
working
on
it
that,
even
though
I
would
say
my
understanding
is
the
the
prevailing
standard
in
the
cryptocurrency
community
is
server-based.
Wallets
cloud-based
wallets
right
today,
I
mean
it
just.
It
is
what
it
is.
Some
hardware
based
edged
wallets
are
used,
but
this
is
the
is
the
is
the
the
norm.
The
South's
re
identity,
it
flips
around
your
edge
devices
is
really,
if
you
are
trusting
service,
run
for
all
your
keys
for
all
your
identities,
and
then
also
you
know
your
tokens.
D
E
They
have
to
prove
to
you
that
they're
worth
dealing
with
and
now
we've
turned
the
odds
around
literally
it's
now
they're
the
ones
that
have
to
prove
anyway,
I
just
I
love
the
topic,
because
I
do
believe.
We
can
not
completely
I
mean
that
other
attacks-
it's
not
perfect,
but
at
least
phishing
and
conventional
identity
theft.
That
depends
on
holding
your
data.
We
are
going
to
be
able
to
over
time.
It's
not
happen
immediately.
Gonna
be
able
to
get
download
a
go
ahead.
D
E
It's
interesting
I'd
love
to
explore
that
there
is
a
team
of
Microsoft.
That's
that's
quite
far
into
this
they're,
very
active
and
decentralized
in
the
foundation
and
they're
really
coming
up
with
some
innovative
things
around
key
management
here,
but
I'm
just
to
make
it
clear.
The
baseline
that
we
recommended
to
DHHS
is
if
you're
going
to
have
an
edge
edge
wall
on
a
device
like
this.
E
The
keys
that
that
unlock
that
wallet
of
the
core
key
storage
is
in
the
secure
element
on
the
device
or
you
know,
a
trusted-
processing
module
so
you're,
taking
advantage
of
the
hardware
level
security,
that's
already
in
the
device
you're
not
doing
it
all
in
software.
Now,
that's
not
perfect,
but
compared
to
a
password
list
that
you
probably
you
know,
I'm,
not
gonna,
ask
people
to
put
their
hands.
How
might
you
have
the
password
list
on
the
Google
Doc?
You
know
we're
going
to
get
a
it's
gonna
get
a
lot
better.
E
It's
not
gonna
be
perfect,
but
it's
gonna
get
a
lot
better.
Okay,
I
knew
if
we
got
in
the
key
management
would
go
really
deep
here.
This
is
great.
This
is
it's
fun
to
do
it
with
that
audience.
So,
I,
just
I,
wouldn't
want
to
stress
with
DKMS,
is
by
actually
standardizing
how
we
can
do
this,
making
an
open
standards
so
that
you
can
get
a
wallet
from
you
know,
Evernham
or
Microsoft
or
IBM,
or
you
know,
Red,
Hat
or
anyone
else,
and
there
could
be
a
standard.
E
Open-Source
wallet
in
the
hyper
ledger
indie
project
and
they
speak
DKMS
they're
gonna
be
interoperable.
You're
gonna
be
able
to
move
from
one
wallet
to
another.
Okay,
and
that's
that's
our
goal.
There
now
folks
are
like
well
what
what
goes
in
this
wallet.
Okay,
this
is
an
identity
wallet.
So
the
first
and
foremost
thing
that
goes
in
there
is
there.
Dudes
DIDS
are
associated
with
keepers.
It's
the
address
of
the
public
key
and
the
key
pair
right.
E
What
also
goes
in
there
is
you're
actually
keeping
track
the
endpoints
right
if
I
hold
this
wallet
and
I'm
using
one.
We
called
the
agency
two
for
cloud
agents
to
communicate
with
this.
I
can
turn
around
and
move
to.
Another
agency
I
hold
the
keys
here.
I
hold
the
endpoints
here.
I
just
need
to
tell
all
my
relationships.
Don't
talk
to
me.
There
now
talk
to
me
here
right,
so
I
can't
get
locked
in
by
a
service
provider
that
way
Wow.
E
So
now
we're
gonna
go
zero,
not
scriptable.
If
you
actually
want
all
those
credentials
to
be
zero
knowledge
credentials,
then
you
use
something
called
a
link
secret.
When
you
have
a
credential
issued
to
you,
a
special
secret
you
give
just
to
the
Department
of
Motor
Vehicles
and
they
use
crypto
to
then
give
me
back
an
encrypted
version
that
credential
I'm,
the
only
one
who
can
produce
proofs
from
that.
Okay
I
am
NOT
a
deeper
expert
in
zero
knowledge.
E
Crypto
I
am
I'm
a
connoisseur
I'm,
actually
a
worshipper
of
the
zero
knowledge
crypto
cryptographers,
because
it
is
the
best
black
magic
and
all
of
crypto.
As
far
as
I'm
concerned,
I
do
want
to
make
it
clear,
sovereign,
as
a
network
has
standardized
on
it
when,
when
the
CTO
and
the
of
Evernham
was
the
chair
of
the
sovereign
technical
governance
board,
put
the
stake
in
the
ground
about
that
about
eighteen
months
ago,
I
thought
it
was
nuts
I
thought.
Look.
E
People
have
been
trying
to
do
that
for
a
long
time,
and
now
you
think,
just
because
a
blockchain
we
can
actually
get
the
whole
world
to
adopt
zero
knowledge,
crypto.
Well,
looking
back
on
I
think
was
the
most
farsighted
decision
he
could
have
made
because
you
know
influence
after
insult
right.
Stewards
started
to
get
on
board
with
that.
It
was
actually
one
of
the
biggest
thing
was
convincing.
Ibm
to
become
this
steward
cisco
has
become
a
sovereign
steward.
It's
because
we're
actually
leveraging
blockchain
technology
and
that
crypto
to
solve
these
problems
in
a
broad
way.
E
So
what
this
means
is
all
the
credentials
in
your
wallet
are
going
to
be
issued
using
zero
knowledge
crypto,
which
means
when
you
need
to
go
and
prove
something
like
your
age
when
you're
going
into
a
bar,
the
QR
code
that
you
will
scan
or
the
table
scan
will
give
them
access
to
one
thing
that
they
asked
for,
which
is:
are
you
over
21
in
this
state?
It
is
21
here
in,
but
a
while
since
I've
been
guarded,
that's
all
the
info.
E
And
it's
not
saying
hey
the
primary
goal
of
hyper
ledger
in
Deus
now
to
build
the
universal
crypto
wallet,
but
over
time
we
think
you're
going
to
have
those
functions
built
into
one
identity.
Wallet
make
sense,
go
ahead.
Oh,
oh
sorry,
gosh
I
I
tend
to
what
an
audience
in
this
thing.
I
know:
I
am
talking
about
a
crypt
anyway,
no
I
am
talking
about
a
crypto
token,
a
crypto
currency,
token
yeah
I
tend
to
I.
Forget
I
heard
a
great
story:
Kim
Cameron
and
identity
architect
of
Microsoft.
E
Was
it
the
European
identity
conference
and
there
were
a
bunch
of
sovereign
folks.
I
wasn't
there
this
year
there
were
folks
there,
they
were
talking
to
him
and
one
of
them
said
and
they
were
explaining.
Yes,
there
is
going
to
be
a
crypto
currency
token
for
the
sovereign
network
and
he
was
like
wait.
You
can
design
a
single
token
to
work
with
the
whole
network.
That's
not
the
way.
You
know
Oh
auth
tokens
work,
they
say!
No,
no,
it's
not
Oh
a
token
it
was
like.
E
E
That's
a
very
good
point,
and
again
we
could
go
deep
on
that.
There
are
places
where
you
probably
don't
want
to
do
that,
in
which
case
they,
okay,
I'm,
actually
going
to
cover
at
least
one
of
the
key
points
about
that
that
audience
seemed
to
be
fascinated
about
which
is
okay.
I'm
gonna
make
two
points
here.
Last
two
points
about
a
key
management:
a
lot
of
the
hard
problems
in
key
management
get
easier.
When
you
have
these
clout
agents,
and
one
of
them
is
backup
in
recovery.
E
Okay,
another
one
is
monitoring
of
your
own
just
the
way,
as
you
use
a
credit
card,
you
know
your
credit
card
company's
monitoring
those
transactions
to
try
it
for
fraud,
alerts,
right,
they're,
saying
we're
looking
at
what
you're
doing
to
help
make
sure
that
it's
not
being
you
know,
you're
not
being
hacked
well
with
self-serve
an
identity
and
an
agent
or
agency.
You
trust
software
provider,
you
truck
you
can
be
monitoring
yourself.
E
So
if
suddenly,
there's
a
transaction
that
says,
I
want
to
move
all
my
cryptocurrency
and
you
know
in
one
transaction
I've,
never
done
that
before
it's
pretty
obvious.
There
should
be,
you
know,
solve
there
should
be
rules
and
the
agents
they're
gone
okay.
We
need
a
whole
lot
of
confirmation
that
this
is
real,
but
it's
not
being
dictated
to
you
by
a
bank
or
you
know,
by
some
kind
of
intermediary
you're
just
doing
it
for
yourself.
So
four
key
recovery.
There
are
two
basic
options:
they're
fancier
things
we're
going
to
biometric
recovery.
E
When
Peter
does
his
talk
here,
he
can
go
into
those
things,
but
basically
there's
offline
and
social
recovery
and
I'll
cover
them
quickly,
both
of
them
in
in
DKMS
architecture,
leverage,
those
cloud
agents.
So
what
happens
here
is
the
first
principle
is
your
set
of
agents,
because
you
probably
will
have
more
than
one
hour
maintaining
an
encrypted
backup
of
your
wallet
in
the
cloud
you're,
the
only
one
that
has
the
keys
done.
E
You
know
it's
called
recovery
keys
for
that
wallet
live
in
your
rage
agents.
So
now
you
there's
two
options
for
backing
up
those
keys,
two
basic
options:
okay,
one
of
them
is
the
offline
option.
You
print
out
a
QR
code
or
you
use
a
hardware
wallet
and
you
store
that
recovery
keys
offline.
Okay
in
a
safe
place.
E
It's
like
okay,
go
put
that
in
you
know
in
a
drawer
or
a
safe
deposit
box,
but
I
get
divorced,
and
you
know
all
these
things.
It's
amazing
how
easy
it
looks
and
how
hard
overtime,
because
you're
probably
going
to
need
your
recovery
ten
years
from
now
right.
So
these
work
fine,
but
there's
a
another
option
that
cloud
agents
make
available,
which
is
to
take
that
encrypted
backup
copy
of
the
wallet
share.
It
actually
note
you
don't
have
to
share
that,
take
the
recovery
keys
and
and
share
them
with
what
we
call
trustees.
E
E
Fantastic,
so
the
basic
idea
behind
Shamir
secret
sharing
is
it's
M
of
n
right
you-you-you
have
a
minimum
threshold
of
Trustees,
but
you're
going
to
point
as
many
as
you
want.
So
one
of
the
other
things
we
asked
for
that,
we
did
in
the
study
with
BYU
is
once
you
present
people
with
this
idea.
What's
the
idea,
how
many
trustees
do
they
think
they'll
need
the
most
common
answer?
The
meaning
and
the
whole
thing
was
3
out
of
5.
E
Now
I'm,
not
saying
that's
a
good
thing,
we
just
asked
what
do
people
think
you
know
if
they
have
to
do
this?
Another
thing
that
was
fascinating
is
when
you
ask
them,
would
you
use
people,
or
would
you
use
organizations
or
would
you
use
both
now?
You
can
all
put
your
answer
in
your
head.
What
I
was
surprised
to
find
out
is
very
few.
People
would
trust
only
other
people.
E
Organizations
are
almost
always
in
the
mix
and
a
surprising
number
like
a
third
of
the
people,
said:
they'd
only
trust
organizations,
and
then
we
had
a
list
of
the
organizations
they
would
trust,
and
that
was
the
one
thing
that
popped.
All
of
our
eyes,
because
one
organization
swamped
everyone
else.
They
were
far
and
away
there
like
a
third
higher
score
than
anyone
else.
Can
anybody
guess
who
it
is.
E
Close
google
yeah
I
mean
it
was
amazing.
It's
a
word
cloud
and
you
can't
miss
it.
It's
like
that
big
right
in
the
middle
yeah.
So
anyway,
that's
the
basic
idea
and
again
part
of
the
power
is
an
agent.
A
well-designed
agent
working
with
you
on
your
devices
can
actually
just
like
a
social
network,
helped
determine
over
time.
Who
are
your
most
active
and
trusted
contacts?
Now
you
can,
it
can.
E
Have
you
verify
that,
but
it
can
keep
reassuring
your
keys
and
maintaining
them
with
your
active
context
over
your
lifetime
and
even
help
you
set
them
up
with
trustees
and
for
after
you
pass
away
so
we're
talking
about
now
adapting
human
processes
to
the
digital
world
in
a
way
that
it's
it's
amazing,
this
room
can
be
filled
with
lawyers
and
they
would
be
asking
more
questions
than
you
are
right.
Someone
had
a
question.
E
Yes,
you
can
actually
well
you
virt
your
first
round
of
a
backup
or
recoveries,
actually
your
own
devices.
So
if
you
have
three
devices
and
you
lose
one,
you
can
recover
from
two
devices
you
could
also.
You
could
use
yourself
if
you
basically
said
I've
setup
trusted
servers
in
the
cloud
and
you
run
them.
You
can
use
those
as
trustees.
I,
don't
know
if
that
answers
you
a
question.
E
Biometric
surfers
writers
can
actually
provide
you
with
a
credential
biometric
authentication,
so
one
place
is
obviously
on
the
device
and
having
the
device
and
the
wallet
actually
provide
a
credential
that
you
have
done:
biometric
authentication
at
the
device,
so
you
don't
have
to
share
the
biometric
outside
of
the
device,
but
you
get
a
credential
that
it's
been
done
right,
that's
its
pattern,
DHS
very
interested
in
and
we
think
that
local
device
and
biometric
service
version
is
doing
in
the
cloud.
It's
a
powerful
combination.
E
D
E
When
you
want
to
update
your
your
did
document,
it
has
a
new
rotated
public
keys
change,
your
endpoint
anything
like
that.
You
do
a
new
transaction
with
that
blockchain
and
you
write
a
new
did
document
and
that's
yeah,
it's
just
so,
basically
maintaining
a
history
of
just
you're,
just
updating
the
did
document,
it's
a
new
transaction.
Obviously
the
old
ones
are
there,
but
it's
just
like
you
know,
you're,
basically
using
the
blockchain,
it's
just
a
immutable
database
of
dead
documents.
E
That's
why
it's
relatively
simple
compared
to
other
other
blockchain
applications,
but
that's
all
we
need,
because
you
actually
want
to
keep
the
credentials
off
before
I.
Wrap
up
rich
I
do
want
to
cover
this
because
there
have
been
so
many
questions.
All
of
what
we've
talked
about
the
dudes
and
the
the
DKMS
everything
else
remember:
self
sovereign
identity
is
really
digital
credentials.
It's
just
digital
credentials,
done
any
issue
or
anyplace
else.
E
I
want
to
make
sure
that
all
of
this
infrastructure,
if
you
put
it
in
the
context
of
you,
just
need
a
way
of
all--it
and
a
protocol
for
having
a
credential
from
an
issuer
who
signs
it
using
a
D
ID.
Give
it
to
you
that
you
can
consider
so
I'm
using
a
D
ID
and
give
it
to
a
verifier
that
can
verify
both
of
those
signatures.
That's
the
essence
of
what
we're
doing
right.
It
really
is
digital
signatures
on
standardized
credentials
that
anyone
can
issue
anyone
can
hold.
Anyone
can
accept.
D
E
Action,
the
credential
is
a
container
of
claims.
The
claims
are
the
claims
about
your
identity,
so
the
closet,
credential
digital
version
of
this
driver's
license
would
have
a
set
of
claims.
Just
like
the
information
you
see
in
here.
Okay.
Now,
because
we
have
the
great
question,
let
me
just
point
this
out:
this
is
the
overall
standard
w3c
is
creating
in
sovereign
we've
added
two
important
privacy
and
security
characteristics.
First,
these
relationships
are
always
pairwise
unique,
be
IDs
right.
E
These
are
public
key
IDs,
but
when
you,
when
I
go
to
the
driver's
license
of
thority
I
set
up
this
pairwise
D
ID
relationship
when
I
go
to
the
TSA
I
do
the
same
thing.
Nobody
else
needs
to
know
about
those
D
IDs
or
the
keys.
It's
much
stronger
security.
Yes,
it's
thousands
and
thousands
of
keys,
but
guess
what
that's?
What
bitcoin
and
etherium
is
right.
This
is
the
new
world
of
crypto
ii.
I.
Think
even
more
important
thing
is
in
sovereign
all
those
credentials.
E
All
of
them
by
default
are
zero
knowledge
encoded
and
you
produce
proofs
at
the
other
end.
Now
again,
this
blows
a
lot
of
people's
heads
when
the
British
BC
government
has
the
most.
As
far
as
I'm
concerned,
the
most
advanced
identity
team
of
any
government
in
the
world,
I
presented
with
them
and
I
wish
I
have
their
slides
here.
If
we
had
enough
time,
I
was
gonna,
show
you
their
slides
for
the
project
they're
doing
up
there
in
BC
gov
when
they
first
saw
this,
they
wanted
the
hyper
ledger
in
decode
and
they
said.
E
Okay,
we've
got
this
great
new
way
of
issuing
credentials.
How
does
this
work?
It's
still
not
crypto
their
heads
exploded
and
they
curve
me
at
a
conference.
They're
like
this
is
really
cool,
but
we
don't
really
need
any
of
that
stuff.
We
just
need
to
know
we're.
Gonna
do
all
public
credentials
for
businesses.
We
want
to
create
a
big
directory
of
them
and
can't
we
do
that
right
and
I
was
like.
Oh,
this
is
when
it
dies
the
sovereign
technical
team
that
was
at
the
conference
iw
sat
down
with
them.
E
24
hours
later,
they
said
we'll.
Try
it
two
weeks
later
done:
they
got
it's
so
powerful
to
have
it
be
the
default
everywhere.
This
is
zero
knowledge,
crypto
for
planet
earth
and,
if
I
sound
a
little
evangelistic
about
that,
I
should
be
because
it
is
really
cool
and
it's
a
night
villager.
Indeed
the
the
crypto
libraries
for
