The Layer 2 space moves at lightning speed. Just as we start to grasp a particular concept or protocol, changes and new ideas flood the ecosystem. It is exciting and fast-paced, but it can be difficult to maintain an accurate birds' eye view of current developments and upcoming themes. This lightning talk will quickly survey the Layer 2 field and make some predictions around what themes we are likely to see in the coming months.

Because
of
the
work
that
I
do
and
because
of
the
threads
that
I
write,
I
feel
like
I'm
in
a
very
unique
position
to
talk
about
the
themes
in
the
layer,
2
ecosystem
and
the
trends
that
I'm
seeing
so
I'm,
hoping
to
give
you
a
bit
of
a
bird's
eye
view
of
the
layer
2
ecosystem
today
and
what
I'm
seeing
in
the
themes
so
to
start
with
off-chain
data
off
chain
data
in
rollups
is
here
to
stay.
I.
A
Think
it's
fair
to
say
on
the
roll-up
level,
we're
seeing
a
push
to
give
users
a
choice
of
off-chain
data
in
ZK
Roll-Ups
that
looks
like
validiums
and
volitions,
and
for
optimistic
Roll-Ups
that
looks
like
arbitrum,
Nova
and
metastas
optimistic
data
availability.
Really,
the
question
you
should
be
asking
yourself
when
you're,
considering
off-chain
data
for
your
dap
is
what
does
this
mean
for
security?
What
does
it
mean
for
my
users,
funds
and
I
think
that
there's
a
lot
to
consider
there.
A
If
we
accept
that
off-chain
data
is
here
to
stay,
then
we
should
be
thinking
about
ways
to
make
those
daps
more
secure.
Despite
the
off-chain
data,
some
adapts
to
don't
need
all
of
their
data
on
chain
and
those
that
might
need
more
security.
There
are
some
solutions.
One
thing
that
I
thought
was
really
interesting
was
an
article
that
actually
came
out
today
by
paulinia
who's,
someone
on
Twitter
that
I
follow.
You
may
have
heard
of
them,
suggesting
that
we
have
split
security
data
sharding
on
Roll-Ups.
This
is
literally
an
idea
that
came
out
today.
A
So
as
far
as
new
trends
I
expect
to
see
some
implementations
of
this
sometime
in
the
near
future,
but
definitely
not
right
now,
but
that
should
help
with
some
of
the
security
concerns
around
off-chain
data
and
roll-ups.
We're
also
going
to
continue
to
see
progress
and
Innovation
on
the
bridging
Fund
in
front.
A
We
just
saw
Georgia's
talk
about
some
really
interesting
ideas
about
how
we
can
have
composability,
but
some
of
the
things
that
I
want
to
talk
about
are
how
popular
layer,
2,
Bridges
right
now
are
centralized
and
they
keep
the
fees
rather
than
sharing
them
with
their
users.
That's
not
really
a
paradigm
that
we
like
in
the
ethereum
world.
We
don't
really
like
centralized
operators,
we
don't
really
like
middlemen,
so
I'm
expecting
to
see
that
Paradigm
being
challenged.
A
One
thing
that
we
already
are
seeing
hot
protocol
has
announced
that
they're
going
to
be
more
Community
Centric.
So
that's
just
one
early
example
of
sort
of
that
shift.
That
I
think
we're
going
to
see
we're.
Also
seeing
really
interesting
work
around
ZK
proofs
to
improve
Bridge
architecture.
We
can
use
ZK
proofs
to
verify
so
Suez
Bridge
created
a
proposal
called
the
slush
proposal
doing
just
that.
We
can
also
use
ZK
proofs
to
create
like
clients
with
ZK
snarks,
which
is
a
relatively
new
idea.
Succinct
Bridge
wants
to
do
that.
A
A
When
it
comes
to
optimistic
Roll-Ups,
we're
going
to
see
these
protocols
Branch
out
and
really
dive
into
Innovative
optimizations
I've
called
them
optimistic
optimizations,
which
I
think
is
kind
of
fun.
Arbitrum,
Nitro
and
optimism.
Bedrock
are
both
huge
steps
forward
for
the
ecosystem.
Yesterday,
at
the
roll-up
Day
event,
vitalik
actually
proposed
several
possible
ways
that
we
could
decentralize
provers
and
also
diversify,
approvers
and
luckily,
for
us,
both
are
both
arbitrum
Nitro
and
optimism.
Better
Iraq
are
already
architected
in
a
way
that
should
allow
for
multiple
provers
and
different
types
of
approvers.
A
One
of
the
cool
things
about
both
arbitrary
Nitro
and
optimism.
Bedrock
is
that
they're
sort
of
Paving
the
way
for
allowing
validity
proofs
within
optimistic
Roll-Ups,
which
is
really
cool
and
something
I
would
definitely
keep
an
eye
on
Roll-Ups
with
layer.
3
capabilities
will
honestly
be
able
to
eat
up
a
lot
of
the
market
if
they
get
off
the
ground
with
offerings
like
privacy,
daps,
permission
dapps
for
institutions,
games
and
even
creating
space
for
alternative
L1
chains
to
execute,
on
top
of
the
layer,
2
and
ultimately
still
settle
on
ethereum
gaining
ethereum
security.
A
Success
here
will
depend
largely
on
ecosystem
support,
documentation
and
ease
of
use.
This
is
also
kind
of
a
new
theme.
Recursive
proofs
exist
on
starknet
now,
but
they're
still
pretty
new
and
I
haven't
seen
any
actual
implementations
of
layer
threes.
Yet,
if
you
have,
let
me
know
I'd
love
to
take
a
look,
but
I
do
think.
A
Layer
threes
will
be
part
of
the
discourse
in
the
coming
months
and
years
as
all
of
the
ZK
Roll-Ups,
especially
mature,
and
go
to
mainnet
speaking
of
ZK
Roll-Ups
ZK
EVMS
are
likely
to
dominate
the
attention
of
the
layer
2
space
in
the
coming
months.
Zk
EVMS
are
really
exciting
and
something
a
lot
of
us
have
been
talking
about
for
the
past.
A
I,
don't
even
know
how
long
honestly,
since
Layer
Two
kind
of
became
a
thing
and
the
reason
they're
exciting
is
because
they
are
theoretically
compatible
with
existing
ethereum,
tooling,
making
them
much
easier
to
use.
They
allow
for
a
shorter
waiting
time
to
exit
to
get
finality,
and
also
because
they
use
ZK
proofs,
and
we
all
love,
math
well,
I
do
anyway
and
I
think
as
these
protocols
enter
mainnet,
the
debate
will
turn
to
what
counts
as
a
true
evm.
What
is
close
enough?
A
There's
no
question
in
my
mind
that
the
ZK
space
is
red
hot
right
now,
and
I
expect
ZK
Roll-Ups
to
really
take
the
stage
going
into
2023.
If
you
had
to
pick
one
theme
of
anything
that
I've
mentioned,
it's
ZK,
Roll-Ups
and
probably
zkevms
in
the
near
future,
so
it
turns
out.
7
minutes
is
not
very
long,
I'm
literally
being
told
right
now.
My
time
is
up,
so
I
did
create
a
list
of
some
more
Trends
to
keep
an
eye
on
that.
A
So
in
conclusion,
Layer
Two
is
here
it
is
changing
fast
and
it's
bringing
some
of
the
most
exciting
Innovations
imaginable
to
the
ethereum
ecosystem.
And
again
my
name
is
feyna.
Thank
you
all
for
your
time.
Sorry,
for
going
overtime
and
I
hope
that
this
Tapas
educational,
thank
you
faino.
Thank
you.
So
much.
