hello everyone I shower from research
team and today my talk is about toward
eastern 2.0 shutting universe and also
before it's complete and delivered there
is a gap between now and the end game so
what we shall build for it so this is
the well-known is there a roadmap that I
don't need to go through again the
allies quite simple all those faces are
have its own girls and however found the
decide to production let's actually like
it's actually like this so how
impractical is like a twisted a highway
layer by layers and connected so the the
courage of the current approach is much
better than the early shoddy and Casper
design like in the 2017 and where there
were no beacon chain between the East
one chain and is to chain and The
Shining trains are actually they were
depending on the expansion but however
even with the become chain we still have
to comfort the backward-compatible
issues for it and for the design areas
something sometimes is vertical in some
highs is horizontal
and that I recall that that in 2017
research King has received some feedback
from community found the client thinks
that we should have more incremental ism
in the design philosophy that is to add
more to add many small incremental steps
step by step changes instead of a few
large sounder drugs to compare this to
different strategies and for example
when we are building a city with
incremental strategy we should start
from the base construction and then
build the small small houses and then
nearby the small houses we build higher
buildings the last incremental saying
looks like and for the sound ins and
with the southern implantation
we would draw the blueprint very very
carefully and start to contract and
suddenly the castle just landed so I'd
say that current the current approach in
each row is much more toward
incrementalist and design but there's
still something that we need to think
about
so the disadvantage of the incremental
decides that - in the part of you can
see that in my waist on time to build
the face and faces and let's also the
Beco fallacy seeing can see they start a
picot it has a very very good sense of
smell
but we've very limited I'll I sigh so
it's possible they're praised just found
out them but it sounds winked so like
can see that the prey even if read it's
very close to it so so is that in the
local decide so that's why we usually
have to go back elbows and to fix
problem that are hiding somewhere and ok
so classic and I organized survey
recently the survey was for the external
community and especially the developers
and one of the question is what portion
properties or functionalities do we
sorry
do you want to see implemented in East
200 or is to one point X so we got about
sixty nine people answered a structure
and I categorized them with some simple
text below and the top three wishes
there are scalability is proof of stake
and get a free model increment
improvement those three different
requirements but at some point they are
overlapping I'm sorry
[Music]
they are all rapping in the is to old
design map so I select some of the
topics based on the top wishes today to
introduce to you and this three topics
include the abstract and stretching and
application and some significant changes
I will have him English - all shouting
universe so the first one is there one
account abstract so it has been
discussed in the East one point acts as
well that in the abstract account model
all contracts are for world cultures so
there's no all count are forward
contracts so there are two main strategy
why is the after we only abstract the
signature and another one is we do for
abstraction include the nouns gas and
payment and sorry
and with the guaranteed transactions and
also if we plug into the east to e es we
will have the EE can have its own
different execution environment and also
each environment can have different
account abstract model inside so it's
very fixed flexible and very easy to
plug into the one to each other another
topic I want to talk about is the IP 151
five five nine it's the free market
model change
created by italic and Eric corner and so
in this scheme we will have a dynamic
pest free value and this value is
addressed by the lights nation rate so
if the ionization rate is is over 50
percent this special variable will be
well increase and if it's sorry if the
realization rate is under 50 percent
this this very well be decrease so so
since its update automatically
it's allowed user doesn't have to do
more work unless the quality service can
help to define the fair free for users
so it actually it's actually make a lot
of you expert early and the current
state crow so and also the past few is
always bird this design rationale is to
prevent minor or the proposer from
manipulating the field in order to
extract more fries from the user so
generally it will be a more fair model
Leon just a crow and before talking
about shaking I want to mention the
transparent future again some cosmic G
is the finality to off all finality
protocol folder is too old
so the validator the duty of the editor
has three step one is to make deposit to
the east ones deposit country and the
second one is when the block has enough
has to vote for the current epoch the
current change checkpoints and if the
drip point got in enough votes we call
that this checkpoint is justified and
also
if the checkpoint is it if the
checkpoint has to justify descent does
we call it this buck or this checkpoint
is got finalized so that's the basic of
a greater duty and we also know that the
me misbehaved very data never got
slashed so one is - - is that it will
import wholly they were the top two
little fellas from the protocol so after
migrating the tutor for prefers tech
system it will introduce a new economic
model so : Meijer France consensus has
been working on this economic models for
a while and the model is based on the
current forints faith I encourage people
especially that Aramis to take a look
he's a work and if to get feedback for
the economic side so similar to the my
poor we can expand that their work is
taking poor in a few near future and if
the military are not alive for a while
and they can't finalize any choice so
they will be penalized as well so based
on that it's very important to have a
stable networking environments for the
proof of stake very leaders and the next
topic is about the network latency so
this message are the most overhead of
the chatting network including the
attestations which is the vote of the
between the country and the shotshells
and the second one is the translations
so
translations only in the shouting
Network and also there are blogs are
including the beacon block of their and
also the shot blocks so um and we have
costing so the shot block will point to
the beacon block and the beacon park
would refer to the shot block sometimes
that's called a cross link so the
crossing is included in the attestation
data per shot shell and then God
included in the prod in the attention so
also the Shadrin
has its own subnet this very clear
but sometimes the cross shot and they're
working communication is frequent so
with the latest is to speak we have four
million validators 64 start first epoch
and six seconds become black time and we
will lead to sixty four thousand
individual signature on the big tension
but the news is that list individual
signature can be aggregate into the
smaller message in in the shining
Network side we have 64 kilobytes block
data cap capacity and three seconds shot
blocked start time and it were
internally to about like 21 kilobytes
per seconds in per shot so that's the
overhead here and about the networking
layers well it's - oh I used the p2p a
stone-faced networking protocol so under
the under the networking there it's the
pure connection so the Pieta nation it
depends on the pier
discovery protocol which you are using
and the true business logic is it is the
message is forecasting with the sub the
publish and sub subscribe system so we
use the gossip star protocol to support
has the sub Nate messages inside
xiaochun's so yeah but imaging that if
we have like 1000 sorry
tens 1064 chakras and about 4 million
spectators it won't be very large and
also we have to think about the
peer-to-peer network topologies so there
are three possible cases which is the
structured apologist and also the
unstructured apologist and that includes
flooding gossip epidemic and random work
so the gossip is included in this
category and also it's possible to help
to combine a structured and unstructured
ecology into the hybrid model so this is
an example of how can we implement it
simply so in this simple model the very
latest are they can work as a message
inside a shy by using the castle sub for
a comb and only the proposal of the even
slot of the given shot well they only
had the only one who had to collect all
those signatures for the given start so
for the given shot so the overhead only
inside Sundays and only the where data
only the proposals have to exchange the
aggregated signatures when a single one
has to
councillor issues in losing the data
privacy and other nodes can need to
trust the list proposals and if the
promoter doesn't do their work well then
the other the rest of the radiators will
lose the reward from it so it's too easy
another one is implemented by consensus
research team
it's called handle handle allows the
aggregation of thousands of signatures
just under a second and organize is it's
it's done by organizing the connection
in levels so it's more like a structure
to decide it's doing well but we also
need to think more about how can we
utilize the hybrid model more
efficiently so it's two is very cool
it's a Collette but great work so I
think Justin just mentioned about that
very well and also highlight again so we
have the EIP
is research and magicians and is to
speak this art of silent you can found
more deeper knowledge about it
and also there's a bounty initiate by
adjusting and you can get five es if you
found any but under the current we can
change spec and finally I want to say
that even with facing how the the
concern protocol is almost done and
there are some optimizations that kind
hence are working on and generally an
optimist or optimistic of what's
happening and exciting about how can we
establish this problem in the next few
stages and okay so it's I'm co-hosting a
breakout with like tomorrow morning and
if you
interesting knowing more about how the
Europe developed her experience looks
like in the phase one phase two stage
and please come with us and join the
breakout session and if you want to know
more about these two discussions there's
a chance that if you travel next after
the Japan tour and you can come to
Taiwan there's a conference called
crossing and just having crossing Taipei
okay that's the side credits thank you
[Applause]
you
