[Music]
good morning we are ethereum and arm
first of all thank you all for being
here early morning
and um uh well we are running about
later from zero we are either on arm
from Spain
um I hope you find this Workshop very
useful for you all and we have a little
surprise in the end so I truly recommend
you and deeply recommend you to stay
till the end so Mr Diego and my
colleague Fernando they will run this
Workshop so let's go for it and work a
little bit thanks
hello thank you
thanks for attending uh before getting
started with the with the workshop a
little link of of what we do
um
yeah
this is why we are here I mean uh
we want people to run notes at home
to run to stake at home
where it is by running an ethereal and
Armin match or or by running an app node
or by running a client by yourselves uh
whatever
it's very very important for for the
decentralization of the of the network
so this is key and
and that's it if I ask uh if I may ask
how many of you uh run a uh I know at
home
well
not bad
validator
great
and with these kinds of devices with low
power and and result conscious devices
is
uh very good
very good
so what we provide we provide a plug and
play image so it is very easy to start
it just you just need to flash a Micro
SD and and start the device and pretty
much it configures everything and you
have a valuable all the ethereum clients
for start and you can run on a full node
in in a few commands we will see this
later okay
as I was saying uh this is what the the
image does
so uh
it's quite quite easy Uh current
available for Raspberry Pi and Rock 5.
um rock 5 is not yet available okay it's
been released this month I think
um why run and if you know on these
devices well it's
affordable I mean
it's cheaper than other other Solutions
uh expense
little power
there are performant these devices are
powerful particularly now the the rock 5
is is about super powerful device
they are focusing on one task I mean uh
no graphical environments no web
browsing nothing just
it's focused on running on home so you
have all the resources available for
that
uh it's small you can put it in
any corner of your of your house next to
the router or whatever
and uh it's based on on the ERM so it's
good for
uh from a security perspective uh
running several architectures so it's
good
uh this is what the image does uh again
automatic installation includes only
your clients the client runs uh through
systemd devices so we are pretty much
easy to to
uh to manage and we include monitoring
dashboards based on rafana
yeah uh Hardware requirements got a
little higher uh so we are getting some
issues with the with the Raspberry Pi 4
actually uh we just uh being able to to
sync a node with get unstable and nimbus
I think this will get better off I mean
about several weeks because uh client
teams are working on on improving the
performance and and doing some
optimizations we'll see uh the rock 5 is
running great
I'll show you later uh our validator at
home it's running a best way in techu
and it's doing great
so this device can run pretty much every
client everything in client it's it's
super powerful
yeah uh this is what I was saying uh get
unstable plus demos this is the only
combo that that actually works and uh
drop five see that uh it's powerful 16
gigabytes of RAM
nbme it course
pretty much amazing
so uh I'm thinking over now to Fernando
before starting the
uh the the note set up because uh we get
a lot a question that is important for
us
why should I trust your image it's an
image they are boundaries so
foreign
[Music]
how we package uh all clients how we
make the the image so
okay let's go I think the first question
is
and the short answer is no you shouldn't
this should interest us we are going to
provide you uh all the different clients
in a way of Debian packets
and you could ask okay why I should
should you should try to how do I know
that you are not changing anything in
the code or you are not changing
anything in the package Northern trying
to tell me something or doing anything
back but the sure answer is you could do
it at home using learning this
repository in a very easy way that's our
main goal she could do all the same that
we do and create your own image we can
without need anything from us only
ruining these this rubber sorry we will
document this okay it's I had it's in
our to-do list to uh open a develop
section for you to to follow the
follower right and and make all of them
okay
assistant we're trying to do all in a
very automatic way very easy and we
provide a background image I don't know
if you know background background things
are approach from fuzzy Corp open source
product
who tries to to create a developer
environment in a very easy way in a very
programmatic way
I can show you our
here
this stuff
not here
yeah
it is
[Music]
okay there we go
can you do you see anything okay oh
that's that's the way you can find that
we can file the only thing that's still
is prepare an environment in order to
create all the packages okay it's a very
easy and pragmatic way to to do so uh do
you ask to background to create a Ubuntu
machine and install all the software
that you need to create the image all
the packages are basis on the work of
this guy from Jordan Caesar I don't know
I promise okay his surname but this guy
creates a very nice way to create to
automate the creation of a Debian
package or RPM packages or whatever you
know so using his work
is for us is very very easy to create
any any package so if you clone this our
repository I mean do some a very simple
command background app
to create a bigger machine with all the
code inside
for example
you will have to enter in this
directory FFM package Builder and inside
you will be a folder for any client that
we support
for example if you see they get a folder
here it's
[Music]
um
pretty small and simple make file and
with this Mac file you will create the
same package that we are providing you
in our Repository there is a simplest
idea is go to GitHub and from the people
from go ethereum
obtain the version
obtain the this version that the package
has and Creator RPM the only thing that
you are going to do is download the
latest binary enlisted binary for the RM
for for our arm
with this binary and this further
structure you will create a
Debian package the only app or from site
is this small system the unit in order
to to be more easy to to use the
software you could do system start
system stop or system start for the
software all the configuration also is
included it's a basic configuration
[Music]
expensive because we use later
Prometheus and grafana in order to show
you the your ticket statistics
you could see later in our garfana
environment it's also included in the
image so you could simply go to a rebel
and
and the simple a simple get if GitHub is
not probably the speed of the Wi-Fi is
not fast enough to see it but the only
thing that is gonna be is open or
download the latest binary and create a
Debian package these event packages we
will provide you in uh in front of our
Italian repository but do if you don't
understand
you could do it yourself or you could
check if the
um if the m6 md5 sun is the same from
our repository and your your packets and
we'll see we're going you know we will
not change anything in the in the
official binary
okay let's start I don't know if it's
only 40 seconds you know the the skip
will do all for you it will create your
typing packets and you could use it
offline and not trust our Repository
it's it's Imperial uh
uh official binary with a systemd file
assisting the unit
also we provide the same for the for the
SD image
we want to wait these three seconds
okay and the end you will be that we are
raised on it before train but here you
will have your Debian packets for the
guest it's very simple it's pretty easy
it's not
anything strange here it's only uh our
Debian package in order to create it
more easily
and for the
for the
uh for the Ubuntu image that we're using
for all of three devices it's almost the
same thing a small make packet make file
story that here we will download the
latest Ubuntu available for for arm
and and keep it
as one here we'll disable the automatic
categories because if we don't do this
the first room is very very slow because
Montage will try to grade in the first
round and probably if the matches are a
bit old
we will last for very very minutes or
even hours
and the only art that we do is add this
small RC logo in this RC local resolve
damage because here
uh is all the logic we will create a
partition for you we will create all the
new users and permissions in order to
this package room with the
configuration that we made
um in I think in a very simple way you
could do it at home
do not need ask for anything you could
create your own image you could add your
own server if you want you could create
your own package if you don't trust uh
Repository
um that's the thing that okay Judas
shouldn't trust us but you can see if we
are doing anything wrong or we are
cheating doing it at home in a very easy
way
okay
okay thanks Fernando
Let's uh fire up a node
uh we will follow the official our
official recommendation as you can see
it's a pretty straightforward uh
process after you will need to download
our image we already did because you
know
it's here
we unzip it uh all instructions are here
uh
you see
unzip we will flash I have a here
a microSD
so uh
what's the what's the flash process end
you just need to make sure that uh you
uh attach an ethernet cable the the SSD
in in the port in the blue part the blue
board
and uh you put them acros D in in the
slot and just that uh Power device
and the on the first boat
our uh Auto speed will
reconfigure everything and install all
the all the software necessary to run a
node
and creating the keys for the validator
uh so once you uh after maybe 10 minutes
the the device will restart and you will
be a on a recent uh
um online machine that is a pretty much
configured for for running a an
equivalent mode okay
so
uh let's
wait for uh for for it to finish so I
may be
I don't know how much can take this
okay so uh
we will be connecting to uh an a WS
machine because uh we need to to connect
remotely and it's not comfortable
because it is uh
it's more
um it's more it's it's quicker sorry
it's faster and but it's unbased it's
exactly the same that you will uh get
with this uh with a Raspberry Pi or or a
rock type okay we also provide a AWS
image if you want to try uh or imagine
in in your account is uh one click away
from it's just
launching a command I will show you
um
the config file
so you can see all flags that it's
needed to run a client again the token
and the two points in I was saying
is this URL
so let's launch the service
and let's see what happens
so
it's going to start you see that uh
already a loaded a block and state from
the checkpoint
it says that yes there's an execution
endpoint but it's not single it's not
synced so uh
it's gonna start telling uh
the execution line what to do okay
and
that's it for fire up a note
you have an execution layer
a consensus layer you start the both
services
and without limit it's pretty much what
you need to do to to launch a note okay
is that easy
uh again like I said uh
in the intro and Raspberry Pi now just
things with
um
get unstable and like if sorry and
Nimbus because yeah post marriage uh
Hardware requirements went went a little
higher so uh we need to wait I think a
little uh optimizations to come from
from from crime teams and I think I it
will be able again to think with our
clients but we'll see we are not sure of
that uh the rock 5 is running fine I
mean pause merge premiered it's a very
very powerful device and it is a drawing
great
so
um let's go to the validator
um
as you can see
you just need to create the keys and and
running a command to to import the the
evaluator keys in the in the in in the
consensus layer
so
we can go to the second path
from the ATM Foundation
you can see here all the steps that you
need to follow
and
pretty much everything that it's here
it's already done I mean an execution
client is configure you can choose from
from all these four
again
you're good
you can choose uh from any any client
a as well
again you are done
uh validators let's try about one by
later again this
um you now need a a tool for creating
the device or Keys it's already
installed and
actually
um is this one pause it so we can
launch this command straight forward
as ethereum account receivable user
okay
uh that's a English English
password this is a password for uh
your key store okay
yeah
this is these are your keys
please don't
lose this okay write them down and keep
them because without this you will not
be able to withdraw
and that would be a problem
yeah but this is
[Music]
okay let's confirm okay
these are
as you can see it's probably now you can
you have uh Keys here
the deposit data that you will upload in
the 32 is uh deposit
any Keystone where your keys are okay
so let's import them
anything in laptops account
all right
so
we have the validator keys arrays tab so
we just need to
start the service
um
oh
suggested let's see
okay okay
we need to
add here
a
an address
I have one here it's one it's ours
start again
[Music]
okay here it is
and uh
one validator variable so
you just have to go
here
and
know what you're doing
upload here this
um
this file deposit
okay it's this one
it's explained here I mean
uh
it's much
you know you have two options or I can
maybe copy and paste here okay
for you to see
foreign
okay
it's fine and now the more fun process
that it's sending 32 with
and pray for to the regards that uh it's
gonna be fine because it's a
it's a lot of cash I mean
and that's all I mean uh
it's uh as you as you can see it's it's
a simple process
if you have some line of skills is fine
I mean but you can do it without
technical excuse as well if you follow
the recommendation
and
I think uh
we are done with this
let's see
for processor
running let's go find
so
um
The Rock five yes
let's connect five
yes we are going to show our validator
running uh I think three radiator right
now with a rock five
and with four five right now is cheaper
than the Raspberry Pi 4 even and
probably twice or three times powerful
so
yeah right now is going to for uh Rock
five whenever it's available again
you can see here
in the motherboard
it's running a rock tip again
and
you can see here
um
processes that are based on Techo
so let's see
this is our evaluator you see that it's
actually publishing at the stations
it's running right now
it's running fine
and uh
the rock 5 is is running both uh both
clients in in
uh at the same time and and with no
problem at all I mean this is a super
powerful device
uh you can we can see a big base as well
now you see it's in sync it's working
perfectly
and
again this device is not yet available
but I think uh we have contact with the
manufacturer I actually uh this is a
prototype from March I think on March
April I don't know and they are already
releasing a batch we have five uh on its
way I mean
I think that it will be available pretty
soon and
super powerful device super uh
a useful device for for running an
ethereum node and
Hope they've released it this month
okay so uh what's left
the last thing okay
now I will uh
post a tweet
yeah
okay
um as I told you at the beginning of
this Workshop
um there is a raffle right now so if you
want to participate uh Diego is going to
post uh in Twitter
are you ready then okay thanks uh if you
follow us in art ethereal and arm
um you just need to post something like
no there we go
okay you have to post I attend to the
workshop and I want to win something
okay that something is a raspberry uh P4
okay and um from now on put the counter
in three minutes uh
uh we're going to stop five five minutes
really okay five minutes we're gonna
stop and somebody wins something today
yes I mean it's it's he told me five
minutes
we just did it
so just saw me three
yeah five okay confirm five
okay uh yeah I was going to Salvia uh
does anybody here I'm pretty sure that
uh anyone here has any question or yeah
okay
what were the rock 5 sell for how much
would it be uh 189 dollars
but you need an nbme disk so it will be
a little higher and you need a
power device and the MicroSD I think it
should be between 1
750 over 400 I mean because total cost
of no
uh well I have four questions so yeah
probably quick uh do you recommend using
a WS instance against running your no
okay no no not at all no this this was
for for the workshop
[Music]
we don't we don't uh want uh people
running out some AWS because that that's
not a decentralized way of of doing this
so no no
okay and what advantages do you see in
running around Valley lasers instead of
delegating the staking
well because it's very important for the
network actually uh
uh is there's a problem with
centralization in these large pools I
mean it's very important that people
stick at home because if one pool or
several pools want to take over the
network there is uh this uh other Army
of nodes that is from the people I mean
and it's very very important to fight
against this kind of attacks to to stay
at home okay and what measures do you
take at home to ensure uptime
to cheer up time well we have uh
s-i-s-a-i I mean one thing that I uh
I want to say is that it's okay being
offline because the protocol is very
generous I mean the the penalties for
being online offline sorry are very low
so there's no problem for being offline
uh you can be uh online 95 for 99 a
whole year and you have and you are good
so don't do don't Overkill I mean don't
do which I don't don't automate things
because
you can business so
it's okay being offline no no problems
no problem thanks
sorry uh one thing that I do that I find
is quite good is uh do this come with
grafana yeah enabled yeah so in grafana
you can add the telegram group as a um
as a notification point and you can set
up an alert on like critical log so it
sends you a telegram message I find
that's like a really really easy way to
just to know when things are up
Paul from from Lighthouse thank you
thanks for your help
okay next one
I'm just curious what your experience is
if you have uh like run on specifically
a bit more constrained devices like the
Raspberry Pi like which of the
implementations are the most efficient
in those circumstances on arm devices on
there but sorry
um like which of the node softwares do
you find run the most efficiently
yeah uh give a spell performance but
it's very optimized and regarding
courses layer uh I would say Nimbus
because Nimbus uses a very low from
memory it's amazing and but anyway a
pretty much
a besides uh everyone that you know that
executes pretty much all the blockchain
all blocks uh and basically when they're
good at uh our Java based and they are
they are a little heavier uh the other
client person Lighthouse numbers get
another man we're running fine I mean
yeah
I uh thank you very much love the talk
love the work um do you have any plans
for saying like nvv boost or anything
like that for integration we are we are
uh
we already package made boots but
um we are a little concerned because uh
they are not every relays but they are
already censored in some transactions
and
uh we prefer to wait and it it works I
mean it works fine and you can even have
a raspberry P3 maybe or or this kind of
of devices because it's very light but
we are a little concerned about
centralization and sensory you know and
transaction censorship
thank you
hey uh
are you cross-compiling when using the
background no official binaries
um the only accession is everyone
because they don't provide the banners
yeah and sorry one more or less question
so I noticed that you're using swap how
is that impacting the io on the on the
boards you know
um the swap for the raspberry piece uh
necessary because you know eight
gigabytes are very tight and it's
created on the on the USB SSD so yeah
it's not the the
is not the better solution but it's
needed so uh yeah it's something that uh
we need to to do
more questions right there okay
there you go
on a device like the Rocks 5 do you have
any recommendations about the number of
validators that it should should have is
there a recommended limit before you see
a CPU binding I have to say uh we are
running three but I think that uh it
will be able to run a lot I don't have a
figure to to give you but I think that
uh a lot I mean yeah
hi thanks for presentation I came a
little late so I'm not sure if that was
discussed um do you know if somebody
working on an incentive
program or protocol similar to helium
where
um individuals takers that can you know
prove that they're running in a location
that doesn't have high density gets a
little bit of incentive no I'm sorry no
okay because that would be helpful for
the centralization yes
I guess so yes but I not have an opinion
about us because I don't I don't know
what's up
you know sometimes you you cannot answer
or but always the point to learn is
there any other question yeah
right there
so for the Raspberry Pi 4 you said you
use SATA
if I'm not mistaken with the compute
module you use like SATA over use over
USB right that's your setup
um
excuse me industry
USB yeah yeah but for the compute module
with the i o Port you can actually
connect it connect you can use nvme as
well
I don't know if you've tried it out you
can yeah you can do you can do does that
help with any of the performance issues
it's very similar I mean it doesn't make
a difference I think well if the if some
of the performance issues are because of
i o stuff then it might help yeah but
you are um
you know they they use B3 is the
butternut here so
no but so the compute module has
supports nvme sorry sorry sorry I
misunderstood and we we didn't try uh
the computer model no we didn't try it
uh but uh I guess it will be will be
better yes yes
thank you
one more there
there running out of time maybe one or
two questions just really quick I'll
follow up on the USB 3 thing but you
have documented which USB adapters works
and also which USB 3 as the modules uh
um the best option from our experience
is uh anesthetic Bridge
uh which is a little advice that
connects this is a SATA to to USB 3 that
works very well uh you can use uh use
portable USBS
such as uh crucial or or Samsung T5 t67
t7 you know
has a little uses but uh yeah you you
can I you can actually
um
the use a lot of a lot of options so
it's difficult for us to to test
everything but
recommendation our recommendation is the
static Bridge yes it works right right
uh what's your opinion on shared pools
taking
uh we are very we are big fans of
rockpool
uh actually uh we are in contact with uh
Joe clappies
they are running uh rocket pool in the
rock 5 as well and yeah this is uh this
is a way of lowering the 32 barrier uh
in a decentralized way yes it's very
nice I am we are big fans of of Rocket
pool so yeah we recommend that
we have time for one or maybe two
questions uh anyone
nobody everything is clear
sure
uh no it's not in the no it's not
confused I was asking if you have the
graphene nope
[Music]
it's uh because the part of you know you
have to connect to the 3000 port and
weekend okay
okay
um
okay so as I told you before
um
we're given a gift
this ruffle so someone in here is going
with
something pretty interesting because the
raspberry P4 for free of course
so the winner is
and just flash prepare for I just love
to prepare something sorry
we are going to we can see we are
running a
a random number don't be tricky
we can see it in the screen
there are nine participants
should all happen and number two
participating number two please
after he's gone maybe
dude is not here
okay he went away for so the next one is
number eight is
fingers crossed that he's here
Alex Alex Smith whoa winners pass for
him
so far it's gonna explain you yeah
yeah
okay congrats so
um uh thank you for and and Diego it's
been a pleasure to share this uh their
knowledge and and all of you this
morning I just want to remind you that
we'll be uh tomorrow downstairs at the
booth uh with our well you'll see
perfectly ethereum on arm okay and we're
gonna be there if you I don't know if
this tonight comes up any further
question will be there uh the whole day
right yeah so thank you all and I don't
know if you want to add some words
thank you
okay thanks guys thanks a lot thank you
