Revolutionizing decentralized computing Alexandro Dali
2
:on Acura Mobile Device Network, part one.
3
:In this episode, Dr.
4
:Gemma Green sits down with Alexandro Dali,
co-founder of Acura, a groundbreaking
5
:platform that's transforming the
decentralized computing space.
6
:Alessandro shares how accuracy allows
people to onboard their smartphones
7
:to a global network, creating
a powerful computing resource.
8
:With over 106,000 devices and
800,000 CPU core already connected,
9
:they explore how this technology
gives mobile devices a second life.
10
:The security advantages of trusted
execution environments and the
11
:innovative token economics that
make the system sustainable.
12
:With his background in mobile
security, as former lead engineer at
13
:Credit Suisse Alexandro explains how
accuracy is creating an unstoppable,
14
:decentralized computing network
spanning 140 countries that rivals
15
:traditional data centers in capacity.
16
:Jacob Stanler from Power Ledger
also joins the discussion.
17
:I'm your co-host, Anthony Perlin.
18
:Whether you're an investor or
a startup looking for insights,
19
:it's time to get unblocked.
20
:Jemma Green: Alessandro,
welcome to Unblock.
21
:You are a co-founder of aist, which
is really gaining attention in
22
:the decentralized compute space.
23
:For those that are new to that, could
you walk us through what AIST is
24
:and the problem that it's solving?
25
:Alessandro De Carli: Yeah, absolutely.
26
:Hello Gemma, and thank you so much
for, uh, having me on your podcast.
27
:I'm very excited to be here.
28
:What actors does.
29
:In a nutshell is it allows people to
onboard their mobile device, so their
30
:smartphone and dedicate the compute
power that that device has in it to
31
:the network so that somebody else is
capable of utilizing that resource as
32
:a compute unit for their project to
host something to calculate something.
33
:Or even to observe something.
34
:That is what AC is doing in a nutshell.
35
:Taking the billions of phones out there
that get churned through regularly,
36
:and every year we have about 1.4
37
:billion of new mobile devices
that reach your pockets, right?
38
:But that also means that every year, 1.4.
39
:Billion devices land on the secondary
market, and Accu gives them basically a
40
:second life and allows people to really
participate in a super decentralized
41
:network with their mobile device.
42
:Jemma Green: Great.
43
:And how many mobile phones are
connected to the Accu Network right now?
44
:Alessandro De Carli: Well as we
speak right now, and this is a
45
:number that you can look up live
because the network is already live.
46
:We have 106,000 mobile devices connected
offering their compute to the network.
47
:Jemma Green: Amazing.
48
:And what does that translate
to in terms of like the amount
49
:of storage that's available?
50
:Alessandro De Carli: I think ultimately
storage is maybe the thing where mobile
51
:devices don't shine the brightest.
52
:However, where they are amazing is in
the compute density, and with these a
53
:hundred thousand plus devices, you end
up having more than 800,000 CPU cores.
54
:And many people think that these CPU cores
are less performant than let's say, the
55
:ones in servers, but that's not the case.
56
:There is a CPU benchmark score that
does not discriminate between server
57
:CPUs and mobile CPUs, and you will quite
quickly see that, especially because of
58
:the Apple chips, but also the Qualcomm
chips that are in Android phones.
59
:They actually are pretty much and
very high on top there, so you really
60
:do get a lot of compute and these
devices also have quite a lot of ramp.
61
:So compute and ram is where they excel at.
62
:Let's also not forget, especially now
in the era of AI and whatnot, the GU of
63
:the mobile device, there is something
really special about it and it is
64
:that mobile devices have a so-called
unified memory architecture, and what
65
:that means is that your CPU and your
GPU are capable of utilizing the ram.
66
:So if your CPU gets.
67
:24 gigs of ram, which some glasses do
have, then your GPU also gets that,
68
:which is, uh, interesting for running
things like LLMs and so on and so forth.
69
:Jemma Green: Got it.
70
:Alessandro De Carli: But
it's not necessarily the
71
:reason why we started this.
72
:Oh, because my background
is in mobile security.
73
:I used to be the lead mobile
security engineer at, uh,
74
:credit Suisse back in the days.
75
:And basically, I.
76
:Built a very deep relationship with the
security aspect of mobile devices because
77
:about 14 years ago, I then decided to
leave the bank and create an own company
78
:that was offering mobile security to very
large enterprises all around the globe.
79
:We have four out of the five
largest defense companies
80
:in the US as our clients.
81
:And that's also why I ultimately started
Accurus because if you want to create
82
:a decentralized compute network, there
is no other way than having it secure
83
:because there's two aspects that are
really, really important for a real world
84
:adoption of this technology, and one is
that nobody is capable of faking hardware.
85
:That's where distrust of execution
environment comes in Really, really
86
:handy for mobile devices, and you
can basically see the proof of that.
87
:If you go on social media channels
like Reddit or even YouTube and the
88
:type accuracy, you will see a ton
of people showcasing their setup.
89
:But the other aspect is also
the fact that you're able to
90
:run the compute confidentially.
91
:So let's say you have iPhone that
you're now onboarding onto accuracy.
92
:If I need to compute something like
running an LLM and want to give you that.
93
:It's really important that you're not
capable of inspecting the data that I
94
:share with at LLA because otherwise,
yeah, basically confidentiality really
95
:matters in this case, because otherwise
nobody's going to use a more public
96
:kind of version of a cloud, right?
97
:Mm-hmm.
98
:So that's ultimately the
reason why I started with aist,
99
:but then realized the scale.
100
:Jemma Green: Got it.
101
:I mean, I think it would be helpful
to get like contextualize the scale.
102
:You said you talked about
like 800,000 set use.
103
:What does that translate to in the
way that, like how does that compare
104
:to, say, a data center or some other
metric that they could ground that in?
105
:Alessandro De Carli: I mean,
there's many ways to compare this.
106
:The standard mobile device has about
eight core and eight gigabytes software.
107
:This is a median modern device.
108
:Today, if you take a look
at something like an AWS.
109
:They offer you also servers that have
that, those specs, but those servers will
110
:cost you per month around 200 to $300
with those exact same specs in terms of
111
:compute and run that you get out of it.
112
:Mm-hmm.
113
:So now ultimately you are
able to run a hundred thousand
114
:compute units on the network.
115
:Which will translate to a small to medium
sized data center here in Switzerland.
116
:So basically, if you take a look
at Green, which is a data center,
117
:which is posting one of the, uh,
hyperscalers is not official, but I do
118
:know that, and they have about 50,000
compute units in their data center.
119
:So Switzerland obviously is not a
huge country, and the compute units
120
:tend to get way more if you go in a
country such as the us but for Swiss
121
:scale, and this is basically where
we are located, we already would have
122
:the crowdsourced capacity of two data
centers ultimately in terms of compute?
123
:Yeah.
124
:Jemma Green: Mm-hmm.
125
:Gotcha.
126
:That's useful.
127
:How do you guys make money?
128
:Like is it the same model as Amazon
Web Service who you mentioned or
129
:other cloud service providers?
130
:Like how do people pay for the
service and how do the participants
131
:in the network benefit and how
does that curious make money?
132
:Alessandro De Carli: So it's
important to say that the.
133
:Network.
134
:The accuracy network and protocol is set
up in a very, very decentralized way.
135
:This means that there is an entity that
bootstrapped the whole thing, and this
136
:entity is called the Accuracy Association,
and it's a nonprofit association which is
137
:located in Switzerland and basically is
there to be kind of legal entity that has.
138
:And Kick started this network, but it
is a completely decentralized network.
139
:So now that it's out and it started,
it's not like the Actors Association
140
:would be capable of stopping it anymore.
141
:And that's.
142
:One aspect that me personally I find
very interesting because ultimately
143
:similar to how Bitcoin operates,
and no single entity is capable of
144
:shutting that down for accuracy.
145
:Now, instead of the service of having the
ability to transfer value, you have the
146
:ability to provide and get the compute
like decentralized compute, right?
147
:This all around the globe,
no matter where you live.
148
:We have now more than 140 countries
and that we're covering with people
149
:offering computes in those countries.
150
:That's something would never have
been possible with a centralized
151
:setup because all of a sudden
you need to create all these
152
:subsidiaries and maybe some countries
are more interesting than others.
153
:So you wouldn't think of it
that way when Yeah, calculating
154
:the business case around it.
155
:So now we have this very, very accessible,
unstoppable network all around the globe.
156
:The question is, how does value
get generated and the value
157
:that is being generated comes
from your real mobile device.
158
:So there is the security
aspect that I mentioned before.
159
:We have a couple of companies
that heavily leveraging that one.
160
:There is one company that is using
this to wrap and unwrap bitcoins.
161
:They're securing about a hundred
million dollars worth of bitcoins
162
:just with accuracy alone.
163
:That service is obviously a paid
service that people are then paying
164
:in accurate tokens and how the.
165
:Model around the network works.
166
:Is that similar to how Bitcoin
has a fixed inflation that gets
167
:distributed among whoever is
participating in lock production?
168
:With ura, you have a fixed inflation
that is distributed among whoever
169
:is participating in providing
compute and is also advertising
170
:their compute availability.
171
:Now whenever someone utilizes compute,
what you end up doing is that you
172
:completely just burn as kind of compute
fee Acura tokens, so that ultimately you
173
:do have a way to generate that flywheel
wheel right, and counter this inflation
174
:that I mentioned in the beginning.
175
:So ultimately, if you're able
to reach a usage capacity.
176
:Of about 20% of the network.
177
:The whole, yeah.
178
:Economics is designed so that the
supply starts to become deflationary,
179
:and that's also where the, the
value ultimately can be captured.
180
:Jemma Green: Got it.
181
:I mean, I think people that are deep
in the blockchain space will totally
182
:understand what you've just described.
183
:But for people that are perhaps new to
the topic and are listening to this,
184
:could you just explain in, in a bit more
layman terms, like the commercial model
185
:and the business model for people to
get paid and how accurate makes money?
186
:Alessandro De Carli: Yeah, absolutely.
187
:So if we take a look at a network
that maybe people are more
188
:familiar with, the Bitcoin network.
189
:The way the protocol works is that it
is a blockchain and the most important
190
:thing is to create blocks so that
it can offer its services to people.
191
:Now, in the context of Bitcoin,
that is the ability to transfer
192
:value and hold value, right?
193
:The this payment idea behind it
Perus, the idea is that you basically.
194
:Purchase compute and consume
compute similar to a Bitcoin miner.
195
:This is the entity that
generates those blocks.
196
:Also, entities on the Acura network
get rewarded with the accuracy token
197
:whenever they are kind of advertising and
onboarding their compute onto the network
198
:and whenever that compute is being used.
199
:So what this ultimately translates
to is that you're able to have
200
:or get rewarded with a token.
201
:This is the accurate token that
you then ultimately will be able to
202
:convert into whichever currency that
you want through a exchange, be it a
203
:decentralized or centralized exchange.
204
:It's very similar to how Bitcoin
mining works in those regards.
205
:Great.
206
:Jemma Green: And then for Accurus
itself, how does it make money?
207
:Does it take a percentage or
is there some other model?
208
:Alessandro De Carli: So accuracy itself
only requires money to be able to
209
:fund and foster and promote and make
visible the whole protocol and network.
210
:It has not the purpose, like the
Accuracy association just to be here.
211
:Here, it has not the purpose to
pursue any profit making activities.
212
:However, obviously there are
tokens around and how this.
213
:Mission can be fulfilled long-term
is through a treasury, which is
214
:then on chain, completely on chain
controlled by the token holders,
215
:and that treasury is constantly
being replenished by the inflation.
216
:So that ultimately you
then as a token holder.
217
:Will be able to decide which activity
makes the most sense at that specific
218
:moment to further grow the network.
219
:So it's very much aligned
with its community.
220
:Once the whole system is completely,
let's say at some point, maybe you will
221
:not even require an accurate association
anymore, similar to the fact that there is
222
:no Bitcoin kind of entity controlling it.
223
:This is also the power behind these
decentralized networks, right?
224
:It's, it's all kind of designed and
set up with some crypto incentives and
225
:that works around around the token.
226
:Now, you may ask, okay,
how are early contributors.
227
:Being rewarded and whatnot.
228
:Obviously early contributors also
do have token allocations and are
229
:incentivized with token locations
such as the team behind hackers.
230
:So there is a very much an
alignment for the token holders
231
:and the early contributors there.
232
:Jemma Green: Great.
233
:Thanks for unpacking that really
simply as well as in the more
234
:complex terms, Alessandro.
235
:Jakob Stammler: Absolutely, and I think.
236
:Just kind of going off of what you've
already said in this regard, I think
237
:you are obviously not just part of
this Urist association and a co-founder
238
:of this accuracy protocol, but you're
also one of the founding members of
239
:the Deep End Association and with Deep
N Networks where accuracy obviously
240
:is part of the deep end space.
241
:There's always a question of token
ons, and you've mentioned that people.
242
:Pay for some of the services.
243
:So the demand side of accuracy services
are paid for in the A CU token.
244
:Of course.
245
:Then there's a question about when
this token rises, doesn't the service
246
:become more expensive and not as.
247
:Available anymore to your partners.
248
:So how do you kind of bridge between
this supply side, hope for the token
249
:to increase so that you as a processor
have a return on your token that
250
:you receive, and the demand side
that uses the token to pay for it.
251
:I know you have a dual token system.
252
:Maybe you can elaborate on
how this factors into this
253
:whole, um, process as well.
254
:Alessandro De Carli: Yeah, absolutely.
255
:I think it's a very clever question
because it's also a question about the
256
:long-term sustainability of the project.
257
:As we all know with crypto projects, the
value of the PO is ultimately what the
258
:market decides that that value should be.
259
:Right?
260
:And these can be, especially
for early projects.
261
:Quite a lot of swing and volatility
in the token price, which obviously
262
:would immediately hurt a system where
people cannot really plan ahead on
263
:how much their compute costs would be.
264
:Right?
265
:Ultimately.
266
:But this is where we apply a system.
267
:And it's just to maybe
close off that bracket.
268
:It's also a bit a vicious circle, right?
269
:Because the, the moment you are
really, really successful and people
270
:are using it would then probably
also be the moment where it becomes
271
:very expensive for people to use it.
272
:So that is a negative feedback
loop that you absolutely need
273
:to take care of and think about.
274
:And I thought about that for a really,
really long time, and with the very first
275
:version of how we thought about billing
and whatnot on the Testnet, we did have
276
:an issue with exactly this topic that
you're mentioning, and I will quickly
277
:explain how the first version worked and
why that version had that issue versus
278
:then why the new version that that we
just launched does not have that issue.
279
:So for the first version, it
was very, very kind of naive and
280
:natural to say, look, whenever you
have computer availability, the
281
:network will pay for your heartbeat.
282
:And whenever someone consumes
your resources, then you should
283
:basically be paid by whoever
is consuming those resources.
284
:Right?
285
:That's a very naive way, non
crypto way of thinking about this.
286
:But after user surveys, what we
found out is that people providing
287
:compute, they don't necessarily
want to be part of this lottery.
288
:They don't want to today earn this
much, and tomorrow earn another amount.
289
:It's way more interesting
if this is somewhat a stable
290
:amount that they're earning.
291
:This allows them to calculate
their ROI and whatnot.
292
:And this played basically in our hands.
293
:So now the new system has a fixed
inflation that is distributed
294
:among all the participants.
295
:If it is a single participant offering
a single CPU, then that person
296
:would get all of the inflation.
297
:If it is many, then you just receive
a fraction of that inflation.
298
:This means if you have a lot of compute.
299
:You receive relatively
little amount of tokens.
300
:If you have not so much compute available,
then you receive a lot of the tokens.
301
:So far, so good.
302
:Right now, how do we do the pricing then?
303
:Well, the pricing is basically
a multiplier on the heart
304
:beating reward that you receive.
305
:Let's say that you're part of this
pool and there is 50 million tokens
306
:that are being distributed annually.
307
:There is 50 million participants,
which is not the numbers at the
308
:moment, but just to have an example.
309
:Then everyone would receive a
single token per year, right?
310
:If now someone would.
311
:Go there and want to purchase compute
from this pool of 50 million participants,
312
:they would be paying five times that.
313
:So basically five Acura tokens.
314
:If you do this, you basically break
that cycle because let's assume that
315
:the price for a single Acura token.
316
:Really skyrockets becomes
very, very valuable.
317
:Now all of a sudden, whoever is providing
compute has a lot of incentive to provide
318
:more compute, and this would then dilute
everybody that is inside this pool of.
319
:People, and that would flash the
price of the actual compute like this.
320
:Although we have everything designed
around the Acura token, it does not
321
:really matter that much what the
ultimate price of the Acura token is
322
:because it's completely self-regulating.
323
:Right?
324
:So whenever there is, uh, very
little compute, then that would
325
:probably mean that the Acura
token is really, really cheap.
326
:That would mean however,
that you would need to.
327
:Pay more accurate tokens to
get the compute out, hence
328
:burning more accurate tokens.
329
:That is how that system works.
330
:But I agree with you that for a
deepen network, this is one of the
331
:most crucial things to think about
because you don't want to be basically.
332
:Deer in the headlights when all of a
sudden you're really successful and
333
:people really want your token and
it becomes prohibitively expensive.
334
:This was the big issue from
Chainlink, by the way, that they
335
:still haven't really solved, okay?
336
:They solved it with just bilateral
contracts, but it's not really
337
:a very decentralized way, right?
338
:Anthony Perl: I was gonna ask
as well, dumb it down for us.
339
:You've got a smartphone,
how do you get involved?
340
:And also I'm interested because
the smartphone technology isn't
341
:kind of built to last that long.
342
:So how do you deal with that kind of
lifespan of technology and the ability of
343
:it to be working well when you need it?
344
:Alessandro De Carli: Those are.
345
:Two really interesting questions.
346
:Let me first start with how
to onboard compute onboarding.
347
:Compute onto Acura is really as
simple as downloading an app from the
348
:stores and then launching that app.
349
:It's really important that Acura never
runs in the background, so if you do
350
:install that application, like you're
the one controlling when the computer
351
:is being provided and you cannot even.
352
:Do this by mistake, because the app
needs to be running in the foreground.
353
:This means that you cannot use it
for anything else on that side.
354
:And this was a conscious design
decision because we didn't want
355
:people to be impacted negatively
in the turns that they started.
356
:And then all of a sudden,
because a big deployment comes
357
:in, that uses a ton of compute.
358
:After three hours, the battery is dead.
359
:Right?
360
:So basically you go there,
you install the app.
361
:You launch the app, and that's it.
362
:You don't need to be a Linux leak, you
don't need to have any PhD in computer
363
:science to be able to onboard compute.
364
:So that's really easy.
365
:And if you go on hub.acura.com,
366
:you will also find out that it's
very easy to deploy stuff on Acura.
367
:So both sites are quite easy, and
you can then manage your fleet of
368
:devices directly from the Acura hub.
369
:Now the other question is how do you
deal with the hardware itself, right?
370
:Because you're saying that this
hardware is not necessarily
371
:made to last for so long.
372
:The first thing to be said
there is that this hardware is
373
:absolutely made to run 24 7.
374
:Okay?
375
:Because if someone utilizes their
smartphone as their alarm clock to
376
:wake up, they never turn off their
phone, so that's already clear.
377
:The device runs 24 7.
378
:It is designed to do so now, if you
want to let it run for a very long time.
379
:The main issue that you're going to
have is not necessarily the aging of
380
:the compute unit or the RAM or the GPU
or the storage, but is the battery.
381
:The battery is the, the main issue that
really where the device ages and where
382
:you can feel that the device ages, right?
383
:I mean, think about it
also as a consumer, right?
384
:If you have a, uh, five-year-old iPhone.
385
:You will probably not want to just
change it because it's not fast enough,
386
:because I personally cannot really
notice the performance difference from
387
:an iPhone that is five years old towards
the one that is now the latest version.
388
:But you will absolutely notice if
your battery is dead after half a
389
:day, and that's typically where people
then start changing their phone.
390
:Now for aist, we have the phones
always twenty four seven plugged in.
391
:There's no people that have
that just running on battery.
392
:This means we don't really
care that much about the actual
393
:battery capacity on that side.
394
:The cool thing about this spur of mobile
devices is that in computer science you
395
:have this thing called Moore's Law, right?
396
:Which basically says that transistors
over time double and the capacity doubles,
397
:the performance doubles and whatnot.
398
:If you take a look at the server,
it's usually being used for 10
399
:years plus, depending on which
kind of use case for a phone.
400
:There's people that change
them after one year, right?
401
:So you have something like one
and a half, two years pops.
402
:In those eight years difference you
made quantum leaps in in technology.
403
:This hardware is also the most
designed piece of hardware
404
:consumers can get their hands on.
405
:Apple invests about $33 billion a
year on designing and crafting the
406
:best possible piece of hardware,
and they make more than half of
407
:their revenue with the iPhone alone.
408
:So ultimately, you're able to just profit
from all of this technological advancement
409
:and very high density in compute.
410
:Because of that.
411
:So ultimately it's something that
plays more in our favor, but than not.
412
:Anthony Perl: And that's
all we have time for.
413
:In part one of the discussion with
Alessandra Ali, we've explored how URA
414
:has built a decentralized computing
network using everyday smartphones.
415
:Or part two delves deeper into
the practical user experience
416
:and real world applications.
417
:Join us as we hear about the
experience of running accuracy,
418
:including its onboarding process.
419
:We'll explore how the system's popularity
created unexpected market effects with
420
:Google Pixel phones selling out across
Europe, the advantages of constantly
421
:upgrading hardware through normal
phone replacement cycles, and how this
422
:technology is making decentralized
computing accessible to everyday users.
423
:Don't miss this thought provoking
continuation of our discussion on
424
:how mobile devices are creating a new
paradigm in decentralized infrastructure.
