hello
earthlings so um ethereum is great we
want to take it to more planets than
only
Earth and when we think about space
Frontier often nerds think about the
space Frontier as some sci-fi or alien
Tech Technologies or for some other
people it's just an empty void which is
slightly less
inspiring the reality is that if
anything of value is going to come out
of it we need to get nuanced and work
with the
complexities
so what we have seen is that in the last
two years
alone more satellites has been launched
into orbit than in the previous five
decades combined so after finally after
after Decades of stagnation we're
entering a space acceleration era and
this is the time where democra
democratization of the space industry is
happening and plenty of startups with
wild ideas are finally taking a stab at
implementing their
stuff with spacecoin what we're building
is orbital roote of trust it's literally
out of this world secure
Hardware Out Of Reach of physical
attacks it's space-based trusted
execution environment or we call it
space te and this serves as
infrastructure for Celestial compute
Marketplace payment layer for satellite
services and from Earth we'll be able to
access it via RPC nodes for evm and
other
networks this this is a real photo from
uh a launch not long ago what we've
built with the space te is
infrastructure for the with our
Aerospace partner cryptos sat we
basically designed build and launched
satellites into orbit since
2021 um last year we contributed to the
EIP 4844 with the trusted setup ceremony
the kzg and aboard the satellites and
the latest satellites are equipped with
the idium connection which is reachable
from any place in the planet and now
we're preparing a set of uh nodes that
will be equipped with more idium
antennas C Edge nodes
um where was it yeah and and essentially
this is immune to any kind of attacks
there
um the the architecture is uh Yang W
session okay thank you for Mike thank
slides so this is actually what you see
is like the the network architecture
which actually is like Network resilient
so we are using the Iridium satellites
which have like the 66 pieces
distributed across the planet with is
the nine in the backup so that's like
the the first line of the our
communication path we are using then we
are using the upos orbital which is like
the provide as the computation
infrastructure currently and thanks to
this actually we are building the space
coin on the top so what actually we can
uh build on thanks to this is actually
like the some kind of protocol with
specific Hardware capabilities and it
will be like resistant to any kind of
the DDOS attacks and the censorships and
in the future we believe there will be
like much more lot of communication the
paths we can use and the computational
capacity we can
get so this is basically like a brief
diagram where actually the satellites
are reachable any single moment so you
can see like in any kind of the
intervals uh some satellites are
actually reachable where actually the
ground stations are the proposing and
then actually the electing and the
voting back and the broadcasting back on
the ground stations so what we are using
this because there's a lot of
constraints in the environment is
actually we used the modified Hot Stuff
one with the instant finality and thanks
to this we actually we retrofitted for
our lower bandwidth with the least
amount of the messages needed between
the satellites so and this actually open
as the requirement like we just need for
the connectivity only one node designed
it as the the leader so this is briefly
like the diagram so how actually will be
like working in the future and what we
are looking forward to implement
currently so we have like the pre
finality on the L2 with the pre finality
with L2 as with the L1 backup whereas
the the state is posted on the L1 which
is actually good for the low value
transactions and for full finality we'll
be using the L1 where actually it's good
for the high value uh transaction and
actually the state will be fully
committed to the L1 on the satellites so
for the security services thanks to this
we can like offer like the space t the
co-processors which enable cases for
that actually we are looking forward to
offer like the secure custodian for the
various Key Management uh systems and
schemes then actually we're looking for
the cosmic entropy and the vrf and
thanks to this actually we can offer
some kind of the secure delation because
like the hardware is like inacessible
for the inspection and the Eternal
bulletin board so what we actually
looking forward up there is that we'll
be implementing the the support the evm
compatibility and we'll be looking
forward to the initial deployment
focusing on the the bridge contracts and
for future extensibility through the DM
risk and the VM based stuff so we are
looking like for the L1 L2 foundations
NPC wallets and the validators and
especially enthropy providers as well so
thank you for the attention please give
us the follow on the Twitter and I think
now it's time for the questions thank
you it is it
is
man peace among
worlds so we have any questions remember
to stand up your hand and I will TOS
this to
you yeah you can have any kind of the
questions we can ask some Physics
there's there
oh we'll be delivered to you
don't worry it doesn't
break uh so this is fascinating to see
so like you know hats off like for
building it what happens is is it harder
to patch because it's in satellites like
you know in on Earth I guess you could
upgrade the hardware or like you know
switch over to a different operating
system like you know if there's a
vulnerability in the OS that's running
on your satellite I imagine that's a lot
harder to go and fix so how do those
challenges come in and the second one
was what happens if one of the
satellites fails and can you still
maintain connection between your L1
nodes so so there's redundancy right you
have actually on each of the units you
have two Linux like hardened Linux
machines and then eventually both you
have the redundancy in case one
satellites goes off um but with regard
to patching ignoring for a moment the
Hardware related stuff which is a longer
conversation but for software we're
actually looking at potentially
implementing some kind of committee uh
sign off so essentially you have it both
P vetted and also it's not just like a
centralized entity that patches and
pushes potentially uh man in the middle
you know unnecessary
things um if I understand correctly from
your slide is that you use IR radiums
satellite correct okay um I understand
uh uh Space X has a lot of uh low
orbital satellite uh but why do you
choose the radiums over space app okay
yeah so for currently like the idium is
like this like it's most oldest but it's
actually most reable you can get right
now it's also expensive but it's
actually thanks to it where is actually
in the constellation is actually quite
have a long sustainability of the
networks but yes the styling and other
providers they're actually coming in the
puff so we believe is actually in the
market of optical Terminals and but we
just wait the satellites being up and
ready so now Starling G will offer for
the satellite providers but it takes
time to implement into orbit so once
we'll be like more viable and of course
cheaper option we will like switch to
that or and have like the
redundancy thank you
okay any more questions yeah there's
from last
question thanks for the presentation uh
what are some first use cases you
envisage and what are some really
moonshot or literally moonshot use cases
that you can see potentially or what
what could be the coolest use cases you
can
foresee it's a bit of a long uh story
but I reckon just some of the use cases
Cosmic Randomness for vrf secure
deletion um MPC application with
co-signing secure Crow processing these
are the things that are applicable
already today um what's maybe moonshot
and very interesting is as we showed the
there's so many launches now there's
like an entire new space like space
native economy right so we foresee a
scenario where there's going to be AI
agents in space making decisions without
having to download um data to Earth So
eventually like there's a lot of
security that is required for for this
to happen like we've seen with the
planet Labs how it influenced uh
Security on Earth and with more assets
in space it's becoming much more
sensitive so we foresee it as you know
at the backbone for expansion of
ethereum into um more planets eventually
or at least outside of pure bounds of
Earth yeah I would like say the the moon
cases is like the the payment Network
between the satellites so yeah how is
it all right please give a big Applause
to these guys it's a wonderful
presentation so
