[Music]
well a note is uh software that
downloads a copy of the blockchain
all the history all the state all the
accounts transactions and it keeps that
up to date as blocks and transactions
take place and it also helps others run
a node so when you start up a node you
ask all the others for the history of
the blockchain
um and this is really important because
the foundation of ethereum is really
like a network of decentralized nodes
and without those
You Know It uh you know why are we here
I guess we could just build a
centralized solution and
um have something quicker and
yeah
so we'll go over four four of like the
main
reasons why I tell people like hey you
should run a node
so uh again supporting the network it's
each additional node that joins is
additional capacity to the network it
makes the network more robust more
secure again more note like easier for a
new node to start up has more nodes to
to get the history from
also
it's really important that we have
people running
nodes that are from different clients
meaning different node teams different
client teams
um right now it's kind of a big problem
um
if you've heard of Geth or Goa Theory go
ethereum right now about 80 of nodes are
Geth and if there were to be a bug in
Geth that would cause quite a problem
for the network
so we'd much like to have users run like
Basu or another mind
um
and uh yeah this makes ethereum much
more resistant
and I'm sure it helps the get developers
sleep at night as well
okay another big reason is to avoid
lock-in
um this has to do with like the problems
of kind of the web 2 that we talk about
a lot centralization
um so uh having a decentralized network
of nodes both helps ethereum from being
uh kind of like
uh locked into maybe a small group of
developers or teams and it also
it enables like additional systems to be
built on top of ethereum and um have
these properties so uh if you you can
build a system on top of ethereum and uh
if designed in the right way a property
can only really be changed if all the
all the users and participants want that
property to be changed when we talk
about forkability this is what we mean
uh one other cool thing is kind of
relates to the last slide is you get to
vote on changes to ethereum if you run a
node
so let's say vitalik and some of his
friends create an update to Geth and say
we want one to eat every block and we're
going to send it to devs.the devs.eth
and they all update their nodes you can
choose to support them by taking that
update essentially voting uh with their
change or you can decide not to and you
can not take that update and just run
the current version that you're running
um so if a lot of users don't update
their nodes if uh the like centralized
exchanges and your wallet providers like
they don't update their update their
nodes then this update doesn't take
place
but let's say like all of those actors
do update
um then it's most likely that this
update goes through and if you don't
have a node then you don't really have a
choice you don't have a vote you don't
have a voice
okay and uh this is a picture from one
of italics blogs uh
again talking about uh
yeah so um if there were to be some sort
of attack on the on the uh ethereum
through this uh like a new update comes
in and it's does something bad it takes
funds
um that would be considered uh like the
attack we're talking about here and uh
all the users all the node operators
that decide to take that uh contentious
update there they may end up on one fork
and all the other
um
users and node operators might end up on
another Fork
and he talks about uh these are kind of
like the three scenarios that would
happen in this case
and uh so we prefer the options like
toward the left so we would want
something like this to fail
obviously and uh however
uh even if it just ends up in chaos
meaning like uh you know maybe half the
exchanges
show one state of the ethereum and maybe
half the you know exchangers and wallets
show another state of ethereum that's
still like much better than uh the
attackers
becoming Victorious
it kind of makes the attack like
extremely expensive even if the attack
doesn't uh you know isn't Victorious or
it doesn't fail I should say it's still
extremely costly
and then an important question everyone
wants to know is can I run a full node
um a lot of people I I talk to they want
to run a node but they don't know if
they can
so here are some of the requirements
um your computer needs 8 to 16 gigabytes
of memory two terabytes of fast SSD
storage that's
this is kind of the biggest problem for
people is is this fast SSD storage
um
even some of like what you might think
is like a really fast external storage
drive like uh you know it's super highly
rated for like moving videos and in
photos it might not be fast enough for
syncing a node
um
uh right now only one terabyte is used
by nodes to store the state
um this is growing about 10 gigabytes
per week
some nodes have options to use less uh
they're kind of
they're just beyond like the
experimental phase they're like they're
solid options but they have their
limitations
um and don't quite maybe meet all of the
uh use cases that people need and then
the CPU is not usually a bottleneck so
um most laptops that are within like
five years old should should do fine
internet can be a little bit of an issue
so you need about 10 megabits upload
download and it needs to be lower
latency connection
um the data cap is can be a problem in
the U.S a lot of Internet providers have
a one terabyte per month cap I've talked
to some people uh here in South America
and they don't seem to have that problem
or at least they're not aware of it and
then definitely can't really run it on
like a slow cellular or Wi-Fi connection
okay I'm gonna quickly talk about like
the SSD types
um kind of the number that you want to
know is this like 10 10K input output
operations per second
um
so yeah nodes they are essentially
writing like tons of like small files
back and forth reading and writing to
have SSD and
um this is kind of like not really a
common rating that uh SSD companies tell
consumers
because it's not quite applicable to
what most consumers are doing with their
SSD
most consumers are just yeah like moving
at large video files storing photos
okay
um internal ssds M2 and vme uh that's
like very popular now
um
within the like 200 range you can get
for this
um and then yeah you probably just want
to stick with that the other options if
you have them like lying around those
might work that's not going to work
uh external ssds uh the reason why like
I I want to emphasize this is because I
think there's a lot of people out there
with laptops and don't have like a
dedicated desktop or a computer just for
running a full note and so
um I want people to be able to run a
full node on their laptop maybe like
while they're not using it or if they
have an extra one
um so check to see if your laptop has
like one of these connections
either Thunderbolt 403 or USB 3.2
okay now this is the interesting part
because these are some of the upgrades
or potential upgrades coming to ethereum
in the near future here
so when you hear proto-dang sharding
that's eip4488 and actually in the worst
case scenario this would add two and a
half gigabyte terabytes per year for
node operators which is just not really
an option for at home node operators
so in one of italics write-ups he said
that like uh
when like if Proto dang sharding goes
through like we also need EIP
all the fours and uh what that does is
eliminate historical data requirement
from the nodes which would save like 500
gigabytes and
um
and kind of like cut down the
requirement on nodes having a store like
all of this data State expiry is one
that
uh is is contentious again what it does
is essentially eliminates the
requirement for nodes to like uh keep on
to certain to store certain transactions
um let's say like
before a year or so and um unless that
state is updated
so uh I
I have a feeling this probably won't go
through
um
so don't count on that stateless
ethereum is is a really cool change and
no storage would be required for the
node so it pretty much eliminate that
two terabyte SSD requirement
um
it would still be good for no for like
some nodes some users to have that block
that history
but it wouldn't be a requirement so you
could run a node and still validate all
the blocks and transactions and and
really
um participate in all those benefits I
mentioned earlier without the storage
but again this requires like vertical
trees and it's a pretty difficult
upgrade so don't quite count on that
uh ethereum portal network is a really
cool uh actually like separate Network
separate Network built on top of
ethereum or to the side of ethereum it
leverages like BitTorrent architecture
and would kind of enable everyone to run
a light node actually like embedded in
their wallet
um so like most of our wallets right now
they talk to like infuria or Alchemy to
get transit to get transactions and send
a transaction uh this would essentially
eliminate that point of centralization
and your light node would actually talk
to other light nodes which would uh talk
to full nodes whenever you send a
transaction so we really promising but
uh quite a bit of work there
I think they want to have
just for a Time reference I think they
want to have something out by like the
end of next year
um
all right the fun part how to run node
okay uh
could I get a quick hands like if you've
heard of dap node or
ethereum on arm I guess
maybe a quarter of the people in here
okay so yeah they're great the only
um difficulty with running a node with
dab node is you pretty much need a
separate computer
um it installs an entire new operating
system which is also can be a hurdle for
people that haven't installed a new new
operating system on a computer
um but they're great they've been around
been around for a while and um I would
say like are pretty battle tested
option two is the command line which is
for you know super technical users
uh and yeah technical users who are
familiar with the command line and um
yeah don't mind monitoring their node
from a flurry of like command logs
um and then this is this is actually
from ethereum.org's website
um
and actually photoshopped nice node here
not photoshopped but like edited the
HTML so this was kind of like
uh the vision for a nice node
um
was like hey we I think we need a third
option one that is uh for like the
non-technical user there's tons of
people bashing it in the ethereum
community uh who want to run a full node
but don't want to hit the command line
don't want to buy another computer
technically it's possible to just
download an app on your laptop
and run a full node so why don't we have
it
uh so I'm hoping someday uh when this
gets to a more stable version that
they'll include me on on ethereum.org
but uh we gotta approve it until then so
I'm going to talk about a nice node
which I am working on and so this is
what the current version looks like
this is our Alpha release version zero
and you can see this is just like an app
running on I think this is Windows
um and you've got both your execution
consensus clients here
super simple stop start remove
you can kind of see like what is it
doing here at the top like okay awesome
I know how much storage it's taking up I
can see like what's the latest Block
it's at at it's at uh how many peers is
my node connected to
and then kind of in line with this idea
that like I want everyone to be able to
run a node I also want everyone to be
able to like
you know no matter what language you
speak uh we'll have a translation for
that language
um and all of these languages uh were
translated by contributors just people
with a good heart who came out and said
yeah I'll be glad to translate like
whatever we can and into another
language so
a nice note
essentially Sports translations we just
need people who speak all of the other
languages to help out
okay hopefully this loads so this is a
design for our next version much like
cleaner UI
at first only the ethereum node will be
available but I'm designing it to be
General so that you can run other nodes
I'll talk more on that so you pick
ethereum node then you pick which client
you want to run we conveniently show you
which clients are minority clients you
can select a few options select where
you want to store the data at
again these are all things you'd have to
do from the command line
and then this will actually take the
screen um I think I'll show it to you
later
um
and then we have to install some
dependencies here and
we just hit start and uh
our node is syncing and running and we
have this beautiful UI to see our node
in everything is great
okay so this was this is kind of a key
um piece of information for a lot of
people is like can my computer run this
node
um no you don't have to go to like
guides or websites to read through
things it's in the app uh the app
yeah we can see like hey is your CPU
fast enough how much memory do you have
do you have an SSD does it have enough
space all that stuff
um
we can do so we do it for you
and this may differ by client and in the
future this may differ by node type
meaning the hardware requirements May
differ some nodes maybe use a small
amount of RAM
others you might use more storage so
we'll give you that green check mark if
you're good to go based on the Note type
a few more screenshots here
um
yeah just wanted to leave these up here
so you could see them without the video
um this is this is really like important
to me um being able to change the
settings on your node through the UI
again to do this now you have to go to
the docs of the client team uh try to
find like the right flag with like the
dash dash uh whatever and hopefully you
format it rightly I don't know if it
needs quotes uh it doesn't need a comma
in between our space you don't have to
do that
with a nice node it's here
okay nice node is cross-platform meaning
it works with Windows Mac Linux
um this is screenshot of windows
looks like it's not going to play
um so yeah again I designed nice node to
be as general as possible meaning as l2s
start to decentralize and provide nodes
um maybe sync with sequencers
nice node
there should be very minimal changes to
support those new node types
and uh and actually like users could
open a pull request to nice nodes GitHub
and and those new nodes would be in in
nice node in the next release
um so for the technical folks nice note
is sort of a UI wrapper around like
Docker containers
um so any any node type that has a
Docker image will be like really quick
really easy to add to nice note
um and uh yeah eventually we want to add
things like staking as well
um so this is a UI screenshot of like
what it would look like if you were to
add validators
and then you can just kind of see like
yeah uh arbitrome does have a have a no
doubt I don't know if um
I don't know how involved it is in their
their Layer Two yet I think it might
kind of just be like a replica node and
not quite uh the same priority as as
um
they're kind of like their own
and then
The Ant and Beyond here is
okay if our if our like web three dreams
take off and web 3 infrastructure is
really where we go to and the users
control we control the platform and
control the data then we're going to
want users to run uh some of these web3
infrastructure nodes so for example like
this video is being live streamed over
live peer and
uh they have a
network of video trans transcoders
um
and then so they transcode this video
and that's that any any one of us if you
have a graphics card can join that live
peer Network and
um
we can use our graphics card to right
transcode that video
um so this is just one example of
yeah like a web 3 infrastructure that
users can participate in and uh
and have more of a say in and it's
something that uh
I think we can support and uh so we show
it here
okay and this
I think this might be the same video
okay and that looks like the same
screenshot maybe I hit it back last time
okay a little bit for our road map
um so really close to releasing uh the
redesigned UI ux
uh and the super simple onboarding
walking you through like the hardware
requirements other things like that
um I want to get more translations
um we're
um we're gonna work on that hard push on
that hard hopefully by the end of
October here
um after that there's some internal
changes that we need to make to support
more node types for the future
um for the technical folks that's uh
Docker compose that means kind of like
there are nodes that have contained
multiple services and so that that will
help those node types
um
and then additional features I think I
can show you these after
um
so yeah no notifications if your node
has an error log like we'll we'll show
you a notification that error log won't
get like lost in your
terminal and you'll never know about it
um
and then you can like search logs maybe
if your internet goes down we'll notify
you
um that your internet was down for a
brief time
and then after that yeah by February of
next year we'd like to add Layer Two
nodes and more web 3 infrastructure
nodes
all right so it's it is critical to
ethereum's Mission of decentralization
censorship resistance and resiliency for
users to be able to run nodes and
um
this is this is extremely important to
me because like all of the other good
things we talk about here
um you know will only last will only
exist will only really be possible if we
have a truly like user-led
um
a culture of like running nodes and if
the core devs continue to make it
possible for users to run nodes so yeah
for like if we want this dream of like
open Global infrastructure super low
transaction fees for the world like open
Financial system
um
ethereum for everyone we need users to
continue to run nodes
and nice to know the mission is to
simplify node running
and thank you gracias artoros
[Applause]
so yeah I want to open it for questions
and um
uh let's see I just want to move it to
this slide uh so yeah real quick if you
want to help uh we need everybody
um
join our Discord reach out on Twitter
um there's a website here you can
translate on uh which I'll get notified
as soon as someone translates
um so that's cool too
and yeah question time
thank you for your time
I've got this core philosophical
question that I've had for a long time
which is I feel and maybe this is a lack
of understanding that full
non-validating notes are overvaluable
because in the end the state is only
managed by full value
so
why does it really matter that they're
more and more
[Music]
to just deploy thousands of full
non-validating nodes which don't make
mistake
to overpower to kind of cycle attack
non-validating Network
okay so
um tell me if I understood your question
right so your question is what's the
importance of uh non-valid non-staking
non-validator nodes like without eth
um what's what's their importance
um
yeah yeah so uh it's a great question
and what it does is uh the non-eth
non-staking nodes actually keep the
validators it keeps the e-stick nodes
honest
so yeah if let's say
some centralized staking service gets
yeah 75 of the validators
um and they want to push through a block
that sends all the youth to them uh the
non-eth uh nodes will say hey that's
like that's a funky block that doesn't
apply that doesn't uh follow the rules
of ethereum that's you're trying to
steal someone's money reject that block
I'm not like I'm not gonna I'm not gonna
take that transaction and share it with
anyone else I'm going to drop it and say
that's invalid so it essentially keeps
them honest
foreign
[Music]
to push another 10 000 into the network
is very easy
so how how strong it really is the is
the defense mechanism
yeah that's that's a good question so
like if someone were to on a some cloud
service just spin up like a ton of
non-eth nodes um
I think it would be I think it would
probably be more costly than
um it would be I think it still would be
pretty costly
um and
I think even if let's say they have
triple quadruple the number of like
honest nice nodes uh then
I think the attack would still fail or
it may in this case uh default to chaos
so I think
I'm probably not the best person to
speak in terms of like hey we need X
number of honest nodes but I think
um sufficiently so so right now I think
it's it's at about like 8 000 and um
yeah I don't know what that right number
is I I was reading one of italics blog
and I think he even said
I'm not sure how many it is it's
probably more than like a few hundred
but I don't know yeah
yeah I I yeah I'm not the best person I
hope the courthouse thought about that
okay
yeah
um
my father could run it my mother could
run it in their home
attack
um so if they get all this set up and I
show them what ethereum is and they put
all this money into it now they have
this money running on this Windows
computer there and it has no battery
backup it has no um they just shut it
down because they they don't want it
running all night well obviously now
they're getting slashed and so you have
a lot of these people who don't know
about these things you know how to set
up a hardware aren't you kind of
concerned about that or maybe they think
I want to set up two they use the same
contract addresses and two and boom boom
boom they start getting slashed if you
can too
have you thought of uh like
yeah that's a good question is like if
we do make it easy to use like we need
to
um also make make it very clear like
what they need to do and
um and then probably also make it very
easy for them to
uh like stop it or withdraw or
um note of notify them
um so yeah if we're going to make it
easy for people to onboard we also need
it that's a great point we need to make
it easy for them to kind of get off or
help them get off
[Music]
yeah I think the quick answer is I would
um in the app we're going to just make
it like super obvious like lots of
warnings like hey this need you need to
have you're an entered on you need to
have this computer up
um
and yeah hopefully it's our solution's a
lot better than the Alternatives like
hopefully we're way better at notifying
people
um when their node does go down things
like that
yeah no no incentives right now
for for a non-eth non-validator note
yeah
so and that's a great Point like if
um
if you're someone who
um like the SSD is like a big uh
commitment for you or purchase like
maybe running a full node I don't want
to discourage you but maybe it's not the
best use of of like your money or
resources like the there are there is no
like direct incentive at the moment
other than obviously like making sure
ethereum
um works and stays up so
um it is yeah that's a that's a great
point
yep
[Music]
it's from personal experience like when
the defense just launched it was also
one of the first uh
[Music]
um
[Music]
I think it's more of a challenge but how
do you build a
one of you
[Music]
know
uh
whatever it is
yeah I mean certainly we want to make it
as user-friendly as possible and we know
one thing we have thought about is like
letting users opt into automatic updates
for their nodes so wherever possible
they don't need to need to do anything
um
and I think that yeah that's that's
probably a big part of of running your
Note is yeah just doing those updates
and then having some sort of like
alerting
um
in terms of like if some some other
problem were to happen like we would try
to diagnose it as best we can but
um
I suppose that I like
for an issue we can't diagnose I yeah I
don't have an answer but it's it's
something I'll definitely um uh keep in
mind
[Music]
yeah yeah the other thing I do want to
have is like if uh I'll like show the
command that nice node used to start the
node so you can just copy and paste that
command and like leave the app if you
want and then you can just go to the
command line and yeah that's that's
something I want to do too right here
[Music]
um
thank you so much
[Music]
my question is uh
when when your team like a build is it's
it's based on like uh there is a
reachers behind like uh for
what kind of age or or what what is uh
um this kind of people that can't afford
like that this is easy to use because
even if this is easy to use for us maybe
that kind of a stance and it selects oh
it's like option all the stuff that we
talk for uh an algorithm or even our job
people
t-shirt behind that like uh this is like
a accurate with this
um age people or not telling the people
whatever
okay so um just to repeat uh for the
stream um it sounds like there's
concerns that uh we need to make sure
that uh if it is super easy to get in to
get started that uh we make
either some guide rails or some some
um
just make it the user aware that what
they're getting into and
um
so yeah I mean what I'd have to say
those concerns is
um I think we we could do something
where
um instead of letting like the user it's
just something I thought of now like
click like yes yes yes yes yes and then
they're good to go like deposit maybe
having some kind of like
um speed bump that kind of thing where
like they have to either like
demonstrate some technical uh
um knowledge of like what they're
getting and then getting into just sort
of sort of like maybe basic quiz or
something like that
um but other than that I mean
um yeah did I did I um address your
concerns was there anything else or um
okay yeah I think maybe some sort of
speed bump just so they can't click
through like super fast and get
themselves into something they didn't uh
know and now this program is taking up
all their SSD space in the background
um
yeah absolutely
right there in the White
uh sweater or yeah I think you were
first but blue shirt
um so if
um if you don't have any and you're not
staking no slashing um if if you're
staking with nice node and uh your node
were to go down it would be slash just
like any other note
that's that's a great question
um his question was could this be a web
app and
um and I I don't think so as of now I
think uh
uh I think there are limitations on the
browser which you can't basically run a
command a web page can't just like run
an arbitrary command on your your
computer but like an installed
application can
um so
um
now the front end part of a nice node we
could separate that out and put that as
a web page
um it's actually uh it's actually like
mostly the front end is basically a web
page it's basically running in
um chromium there's the underlying
architecture for a nice node is called
electron and it basically downloads
chromium and so it's it's like its own
little web browser there with extra
permissions to interface with operating
system
yeah
any other questions
here again
uh right now uh no plans I want to stay
open sources as long as possible we have
been supported by first East acre in a
Sierra CLR fund and then get coin two
rounds of get coin and then we we
recently got a grant from City Dao which
funded the like improved onboarding
experience that I showed you all today
um
and then hopefully we'll get more grants
and stay open source
yep
I've seen people ask that
um
I think if there there could be in the
future and I I think absolutely I think
there are lots of
um groups or foundations
um
maybe like eat steak or the ethereum
foundation who would
provide some incentive I think
the limitation here is probably like you
need to prove that the person running
the node is a human or that perfect
Humanity civil resistance problem so
um
I haven't thought through the whole like
consequences of tying your
Humanity ID to your node but I think
with that people would give out
incentives
um
other than that I don't know uh I don't
know how they would do it without civil
resistance yeah
uh if you're not staking or not
validating there are no no incentives no
yeah no monetary Rewards
[Music]
yeah yeah I mean that's something I've
thought about I haven't like quite
worked on now but uh the operating like
the Apple can know whether you're on
battery whether you're on power whether
you're on Wi-Fi ethernet
um uh right now we don't have like any
internet speed check but that's
something we could definitely add so I
want to I I do in the long term I do
want to make it so that yeah you can
close your laptop a bit the node stops
peacefully wherever you go next you open
your laptop maybe just plug it in you
eat dinner and it's it's sinking like
while you're
uh yeah and then we'll also potentially
like you get we could have a setting
like while you're while I'm working
don't use resources like just run in the
background or like just pause while I'm
working maybe from my typical work hours
um yeah
okay all right anyone else
okay I think that's it I posted the
slides on the nice note Twitter
um there's tons of links in here
um
so uh you can check out the slides there
awesome thanks everyone
[Applause]
[Music]
uh
okay that's it
