DENVER,
COLORADO
–
StarkWare,
the
developer
firm
behind
layer-2
network
Starknet,
announced
on
Thursday
at
ETHDenver
that
it
is
building
a
new
cryptographic
prover,
called
Stwo.
A
prover
is
a
key
component
for
layer-2s,
since
they
generate
proofs
that
are
then
posted
to
the
base
layer
blockchain
–
a
crucial
process
in
linking
the
networks
and
sharing
the
security.
With
a
faster
prover,
processing
transactions
costs
should
be
lower,
which
in
effect
then
will
also
lower
fees
for
users
and
speed
up
transactions,
according
to
the
StarkWare
team.
In
August,
StarkWare
open-sourced
its
existing
prover,
known
as
Stone.
The
new
prover,
“Stwo,”
gets
its
name
from
a
portmanteau
of
Stone
and
Two,
and
anyone
will
be
able
to
run
it
as
well
as
examine
its
codebase,
according
to
a
press
release
seen
by
CoinDesk.
Starknet
appchains
that
currently
use
Stone
will
eventually
reap
the
benefits
of
the
Stwo
prover,
according
to
StarkWare.
The
news
comes
just
a
week
after
StarkWare
and
Polygon
announced
Circle
STARKS,
which
are
a
new
type
of
cryptographic
proofs
designed
to
make
transactions
faster
and
cheaper
for
zero-knowledge
rollups.
Oren
Katz,
COO
of
StarkWare,
said
in
a
press
release
that
Circle
STARKS
will
be
implemented
in
Stwo,
helping
to
“supercharge
Ethereum
by
more
efficiently
generating
proofs.”
“It’s
especially
exciting
that
just
a
week
after
the
new
Circle
STARK
protocol
was
announced
as
a
theoretical
breakthrough,
this
protocol
is
already
springing
to
life
with
the
development
of
this
blazingly
fast
prover,”
Katz
said.
