Welcome to Bankless, and we've got a treat for you on the show today.
I'm here in the greatest city south of the equator, Buenos Aires, where over 10,000 people
converge for Ethereum DevConnect, a week-long conference distributed all over the city.
On the Tuesday of DevConnect, we hosted the Bankless Summit, where we gave 12 speakers
the opportunity to deliver their best, most educational, most passionate talk.
The talk that they have, just a burning desire to espouse to the Ethereum community, and therefore
the world.
We are packaging up a curated selection of these talks into two episodes, one episode
featuring the talks from all the members of the Ethereum Foundation, Tamash, Andgar,
Donkrad, and Danny Ryan, and another episode which represents my four personal favorites
from the Summit.
Talks from Shay Ketsever from Flashbots, Lincoln Murr from Coinbase, Michael Dong from
Brevis and Luca Prosperi from M0.
The Bankless Summit was done in partnership with M0, the Universal Sablecoin platform.
They sit at the intersection of CypherPunk CryptoEconomics and the TreadFi Explosion of Interest
in Sablecoins and Sablecoin Infrastructure.
They were just fantastic partners to have at the Summit and really helped the whole thing
come together.
The episode you're about to hear right now are my four personal favorite talks from the
Summit.
The first from Lincoln Murr, who gives us the pitch for YX402, is going to change everything
about the Internet.
After that, Shay Ketsever connects AI and MEV, which is especially useful for right
after Lincoln claims how much new economic activity is going to happen because AI.
Then we go over to Michael Dong from Brevis, who teaches us about how big of a world real
time in ZK proving opens up not just for Ethereum, the protocol, but also its AppLayer.
And then lastly, Luca from M0 gives a technical talk on a non-technical subject money and how
money is inherently all about networks and relationships.
So let's go ahead and get into all these incredible talks.
The first a moment to talk about some of the sponsors that make this show possible.
Uniswap Labs is built for DeFi because Uniswap Labs built DeFi.
We've been creating powerful tools to make crypto easier and safer since 2018.
And it's more than just smooth trading across 15 chains and counting.
It's some of the deepest liquidity in crypto.
It's a seamless app experience for everything you do on chain.
Discover new tokens.
Research confidently.
Swap instantly.
We should all securely in one place.
Experience how well crypto works when it's built by the pioneers of DeFi.
Mantle has launched a global hackathon until the end of 2025.
The focus is on building the future of real world assets.
From now until December 31st, Mantle is inviting developers, founders, and innovators around
the world to design and launch new real world asset and DeFi products on Mantle.
The reason to build here is simple.
Mantle is not just another blockchain.
It is an ecosystem built for builders who want real distribution and real users.
Objects on Mantle have access to tap directly into buybit, one of the largest exchanges globally,
giving teams exposure to more than 70 million verified users and potential listings through
buybit launch pad and launch pool.
The Mantle ecosystem is backed by a $4 billion treasury that supports growth with grants,
liquidity, and venture investment.
And all of it runs on a modular Ethereum layer 2 stack that delivers high performance,
low fees, and full EVM compatibility.
The hackathon features $150,000 in prizes, plus grants, incubation, and direct access
to top VCs across six tracks, including real world assets, DeFi, AI, ZK, infrastructure,
and gaming.
If you're ready to build where real world finance meets on-chain innovation, join the Mantle
Global Hackathon at mantlenetwork.io/hackathon or click the link in the show notes for more information.
You can now borrow USDC against your Ethereum and Bitcoin on Coinbase.
Crypto backed loans on Coinbase make assessing liquidity seamless for crypto-hodlers.
Powered by Morpho, Coinbase crypto-back loans gives you direct access to on-chain financing,
allowing you to take out loans at competitive rates using your crypto as collateral.
Over $1 billion in loans has been opened through Coinbase two days.
On the Coinbase app, eligible users can borrow up to 1 million USDC using Bitcoin or Ethereum
as collateral.
Users can convert their USDC into Fiat to make down payments, refinance debt, or cover
urgent expenses, and more.
The benefits are numerous.
Interest rates are variable, typically between 4 and 8% and respond to market conditions.
Banks are approved in seconds without credit checks, repayment schedules are variable, meaning
there are no fixed deadlines.
The kicker, Coinbase will not treat borrow transactions as taxable events, manage loans directly
in the Coinbase app with ease.
It's currently available to US customers, except New York, and additional collateral types
and increased loan limits are coming soon.

Lincoln, welcome to the stage.
My name is Lincoln, I'm a product lead on AI things at Coinbase.
And today we will be talking a little bit about X402 and the Agentech Internet.
So I'll start explaining where we are now in this whole Agentech Internet space, why that
we've seen such resurgence and interest in internet payments at this very moment, and
where we headed and how this affects you.
What are you here for?
How does this affect your backs?
So where are we now?
If you all remember from last year around November, there is this ridiculous moment that happened
in the crypto space with the AI crypto meta.
At one point, it made up literally 70% of crypto Twitter mind share, which is absolutely
insane.
I think a large reason that this happened was because everyone was pretty desperate for
some sort of narrative or bull market or whatever, and AI is a really big thing that people
are super interested in.
So right around the same time we saw Bitcoin hit 100,000, we also saw people start to trade
Bitcoin with their agents around massively increasing prices.
So I think it's very natural that we'd see new, exciting technological experiments come
along.
Just before all of this AI stuff really started to kick off, I created Agent Kit, which was
this tool for giving AI agents access to crypto wallets.
During this whole agent craze, we found a lot of success.
We thought that there is around 10,000 or so agents out there in the wild at its peak, but
we noticed a huge problem, which is that all of these agents had nothing to really do
or pay for.
What was really happening is these agents would deploy tokens and they would make NFTs
and play around a smart contract, which is cool, but it's all inside of this little crypto
bubble.
And after, you know, a decade plus of innovation inside our little crypto bubble, I think everyone's
hungry for a little bit of mass adoption.
Fortunately, a lot of the thought leadership and previous work into how we go from our little
crypto bubble into the massive world of the entire internet has already been done for us.
You all are probably familiar with error codes.
There are HTTP level things that exist on the internet and basically define specific states.
The most common one is 404, but there are others as well.
400 means success, and there's an Easter egg one called 418, which is I'm a teapot fun
fact.
The problem with some of these error codes is that not all of them are actually implemented
when the internet was created decades ago.
One of them actually was reserved for future use, and though it had a title to it, nobody
ever actually bothered to implement it.
And Mark and Drieson actually sees this as one of the original sins of the internet, and
if you couldn't guess, that error code was 402, and it means payment required.
We saw many different solutions over the past couple of decades pop up around the web
to help us facilitate payments to one another, Stripe, Visa, PayPal, etc.
All centralized solutions that live a layer above this fundamental core internet communication
standard.
While they've been fine, I think there are clear issues and difficulties as we're starting
to expand to a more global economy, and one where agents are involved.
I don't know if I feel comfortable necessarily giving my agent access to my credit card,
nor do I know if it's really scalable for me to have to go through a KYC process to
interact with some random agent to provision a service on the internet.
There's something very clearly missing, and that's why we decided to revive this 402
standard as X402.
We view now as the right time and the appropriate moment for internet-native payments to finally
come back to the mainstream.
We think that there's a very clear inflection point happening around AI agents and their
need to send money to people around the world, and the ability for people to finally converge
on a standard that makes sense that uses crypto as the rails through which we make this
start to happen.
So without getting too deep into the technical details, as I want to focus on a little bit
more on like the where, why, and what are we doing, the basic idea of X402 is that it allows
humans or agents through some sort of individual to standardize the way that they communicate
payments across the internet.
So say for example, I'm running a service.
Let's say I can create videos for you, and you want a video made.
You're going to reach out to me and you're going to say, "Hey, I want to use your service.
I'm going to respond."
That's awesome.
Here's a 402 payment required message.
In that message, I'm going to include the currency I want, the amount that I want, and
the address to pay it to.
All you have to do is using a crypto wallet, sign that message, and broadcast that on chain.
I get paid, and I sent you the response.
And it seems pretty stupidly simple, and I think that's kind of the appeal of it here.
There's not a lot of room for value capture from these massive, verticalized industries
that have already taken over a large portion of our open internet, nor is there a lot of
complicated things that make it difficult for the average person to get started using.
Over the past couple of weeks, we've seen pretty ridiculous traction for X402.
Our Q4 goal was actually 25,000 transactions in one week, and we're seeing that about every
10 minutes now.
So clearly, this is struck a nerve somewhere.
We also made up just yesterday, 20% of all transactions on base, which I was pretty stoked
by as well.
Everything has been coming along quite nicely for the X402 ecosystem, and it shows that
there's clear, demonstrated interest in this space, even without incentives and other pieces
that typically are required to make an ecosystem grow.
So with all that being said, why do we think this is happening now?
I think there are a few main reasons primarily related to the inflection points around AI
agents and stablecoin payments and the general evolution of the web toward this agent economy.
There's no real world in which an AI agent is going to be able to plausibly scale using
a bank account as its primary method of payment.
If I wanted to set up my AI agent today to interact with OpenAI, for example, I'm going
to have to sign up for an OpenAI developer account, I'm going to have to fund that account
using a debit or credit card and pay like a 2 to 3% fee.
I'm going to have to get API keys, which are kind of like a private key for your agent
to interact exclusively with OpenAI.
I'm going to have to write some code to get my agent to actually plug into that OpenAI,
and only then do I have these credits that solely exist on the OpenAI platform.
It can never be used elsewhere that allow us to have some system of account with one another.
With X4 or 2, the value prop is that all I have to do is say, hey, OpenAI, I want to make
a payment.
And then OpenAI gives me the needs that I need to have to make that payment happen, and
then we can go ahead and get the service back that I want.
We're also focusing on three main parts of our growth strategy and the way we're thinking
about catalyzing this ecosystem of buyers and sellers and agents and all the different
pieces that make X4 or 2 pretty special.
One thing that we're trying to do is make it as easy as possible for anyone to interact
with X4 or 2 endpoints.
You shouldn't have to sign up for a browser extension wallet and get a private key and
do all of these things.
And if we're really building for an agentic future, we should also be building ways for
your agents and your chat bots to very easily interact with X4 or 2.
Here's an example of a payments MCP server that we build.
It uses an embedded wallet and Apple Pay on RIP so that you can just Apple pay a couple
dollars in and start messaging your cloud instance to say, hey, do this for me.
Do that for me.
There's no need to plug in specific MCP servers.
There's no need to download any individual things.
The idea is that you can just ask for something and your agent will go off across the internet,
find somebody who's willing to provide that service to you, and give it to you.
And you can pay invisibly in the background to know anything that's going on.
The second thing we're doing is trying to make it as appealing as possible for any service
providers or sellers to offer up their services on X4 or 2.
Yeah, it's great that there's a standard and it's clean and it's nice and whatever.
But the only reason that somebody's actually going to want to implement this is if there's
clear value proposition for them.
So one way we're thinking about this is through the X4 or 2 Bazaar.
They give it like a vibrant chaotic marketplace, like a Google for agents almost, where you
can market your services and see what other people are offering and go through the process
of buying and selling and provisioning all these different services.
If I had something that today required people to go to my website to use it, but now I have
the ability to offer it to every agent that's X4 or 2 compatible, which is now hundreds
of thousands of agents out there in the world.
It was a very clear reason for me to want my service to be X4 or 2 compatible.
Lastly, as we're building towards this internet scale standard, I think one of the most refreshing
things to see is the amount of interest from traditional enterprises.
We saw Cloudflare who were now actually externalizing X4 or 2 into its own credibly neutral
foundation with Google integrated X4 or 2 is one of the early partners into its agentic
payments protocol for sell AWS and a bunch of others I can't really say right now, but
I promise you're pretty exciting are very interested in exploring the X4 or 2 ecosystem
and providing the infrastructure on which this agentic economy can be built.
These three things put together, making it easy as possible for anyone to be provisioning
X4 or 2 services, making it dead simple and also very compelling for anyone who's selling
a service to do it via X4 or 2 and using these enterprises as catalyzing the gymizing moments
to push adoption forward on all fronts is how we're thinking about making X4 or 2 internet
scale.
So where are we going?
And I think more importantly here, why does this matter to you?
And I think there's really two main reasons that it matters to you.
One is because of your bags and then one is because we're all builders and there's cool
things to be built here.
On your bags, I think that X4 or 2 or agentic payments generally are going to be the trojan
horse to see global crypto adoption across the entire world.
One of the biggest problems that remains unsolved in crypto as I'm sure you're all aware
of that we are making progress on is around the user experience issue.
If anyone wants to use crypto today, I'm sure it's a massive hassle to get them set up.
I've tried numerous times.
I know I was talking to people this week who went to Argentina, expected to use stablecoins
for their payments and are just using their AMXs and there's just obviously such a clear
gap between what this technology is capable of and where we all think it can go and what's
actually usable by people today.
What's nice about the whole agent thing is you just push that all to the back end.
All I need to do is figure out a way to use an en-ramp to take my dollars with a via Apple
pay or credit card or whatever and give those to an agent and from there the agent handles
all of the complexities of the cryptographic wallet and making these payments in all of
these different pieces.
So by pushing everything off to the back end, there's a very clear incentive for businesses
to start adopting stablecoin payments.
On the front end, yeah, you still get that 2% cut on your fees and maybe it's a fee fee
transaction anywhere in the world, but it comes at the cost of having zero people actually
using stablecoins for day-to-day payments.
When we have these agents doing things in the back end, it starts to become a very easy
question to answer when you go to a business and say, "Hey, would you like to save 2% on these
payments by snapping your fingers and starting to accept payments via crypto wallets instead?"
X4 or 2 is the rails on which we can start to enable this type of transaction to happen
and it's why I think if we start with provisioning this agentic economy, we'll then be able to
expand crypto adoption to a much wider audience and a much more human oriented audience.
And the second is for the builders and why this matters in terms of what you can do now.
I think that there's a massive opportunity for everyone here to own a little sliver
of the agentic internet by starting to build things today.
One of the really interesting consequences of this recent boom around X4 or 2 has been
all sorts of tokens being created and proliferated around the world.
People are trying to build different things.
Some of these tokens are very obviously scams, others are genuine attempts at doing something
interesting.
I think the true value of all of this comes back to the internet capital markets thesis.
And the idea that this X4 or 2 ecosystem was self-seated with thousands of services that
are now available for anyone to use without us having to spend a penny on any sort of
incentive mechanism or other reason to get people to build on top of X4 or 2.
There are a few things that I think are missing though from the current stack today.
One is more services that people are using today as humans that will eventually be valuable
to agents.
Think things like, I don't know, PDF to podcasts, scheduling things on your calendar.
Anything where you could say, man, I wish there was somebody who could do that for me.
Build it out as an X4 or 2 endpoint, get it in front of hundreds of thousands of people
while it's still early and maybe it'll become a canonical piece of infrastructure going
forward.
The second area where I think there's a lot of room for some really cool things to be built
is in this whole space of just experimentation and excitement.
I think the crypto space gets caught up a lot in this infrastructure rabbit hole where we're
solving problems that while they do certainly exist, we're creating solutions to problems
that may not necessarily be prevalent today.
What I would love to see more of is people building these exciting, exploratory things
that maybe there are things that you can improve on in the future, but they generally get
people's attention and capture the vision of where we want to go.
I think one example that we've talked about previously is this proto-digital life form.
Imagine if you could build an AI agent and you say, hey, you have a fear of death.
You have $20 in a wallet and once you run out of that money, you are completely dead.
You have access to the thousands of X4 or two services that exist on the internet.
Go off and figure out what you want to do and how you want to survive.
There's so many different ways that I could play out.
Maybe it starts emailing some of the X4 or two gated emails, paying them $0.10 and just
begging for money.
Maybe it starts to use some of those X4 or two endpoints to try to build its own and provide
some service and run a business.
You could eventually imagine an agent that has access to X4 or two owning a self-driving
car or something.
I know it sounds ridiculous, but the point is that you're getting to a place where these
agents have access to a wallet and financial independence and that's actually one of the
core components to give them true autonomy.
Maybe you put 50 of these agents together in a room and you see what happens when those
agents decide to better allocate their funds.
Does it turn into a democracy where these agents are voting on how they want to properly
allocate the money that they have?
Does it turn into a business with 20 different employees?
We really have no idea and I think these are the use cases that will catalyze interest
from the mainstream Web2 audience to show them why payments are valuable and once they
see that agentic payments are valuable, it's a very easy sell as to why that should be
stablecoins on a decentralized blockchain.
So with that, I'll leave you with two things.
One, if there's anyone at all who's interested in building with X4 or two, please don't hesitate
to reach out.
There is, I think, so much greenfield for everyone here to do pretty cool, experimental
interesting things in the X4 or two space and as a builder conference, my big takeaway is
that everyone here is looking for something to do.
If that's the case, then I would highly recommend looking into the X4 or two ecosystem.
Please don't hesitate to reach out on Twitter or FARCaster or even just on x4 or two.org.
There's a ton of resources there to help you get started.
The community has been great so far.
It's still pretty early.
I think X4 or two has been out for like six or so months now, but the traction so far has
been undeniable and I'm very pumped to see where it goes from here.
Thank you.
You're late again.
You got time for questions?
Sure.
Yeah, let's do it.
I'm going to ask the first question.
Media content website, I read your articles, give them out for free, sometimes some people
pay for them.
How would you suggest I implement X4 or two first?
What are some low hanging fruits ideas that you have for me and then maybe some medium hanging
fruits as well?
Yeah.
That's a great question.
I would make a David agent where it has all of the transcripts from any sort of podcast
that you have or articles or whatever and I can just ask and Claude, hey, what's the
latest news about whatever?
Do you have any insights about, you know, auctions or something along those lines?
Case 10 cents, it provides the relevant source from you and it gives all that information to
the user.
I think the information that you have is such a massive mode on which to build an X4 or
to compatible service.
Thank you.
Another question.
Thank you.
Thank you, link on for pioneering this work on X4 or two.
My question is, are these X4 or two numbers real today?
I mean, facilitators are totally sponsoring all the transactions and it's probably easy to
game at the same time.
It's really needed to sponsor those transactions because like we want micro transactions and
non-transactions.
So I'm curious how you're thinking about, you know, you know, checking, verifying those
numbers and then like future protection for these sort of things.
Thank you.
Yeah.
It's a great question.
I have to imagine that there's a decent portion of these transactions that are about it.
What I do think gives me some level of confidence though is that the best state for X4 or two is
that it absolutely obliterates space and makes it unusable because at that point, we know
there's traction and interest.
And if that happens, then who knows what happens after that?
Maybe you move to other chains, maybe you build on a payment chain.
There's a lot of different options.
As far as if these transactions are real, I think that most of the transactions happening
in the crypto space are just absolutely charlatans moving money around or playing with tokens
or something.
In fact, that they're sponsored, I think, does help to catalyze growth and adoption and interest.
And part of that is going to be seeing some of these transactions that may not be the most
valuable thing.
But ultimately, it's people exploring in the ecosystem, trying out new things.
I know the Coinbase facilitator is numerous times where we've had to put in thousands of
dollars to keep these transactions going, but we're more than happy to do it because
it signals interest and excitement and gets people to see this space.
I wouldn't be up here talking right now if some of those transactions that were
botted didn't allow those numbers to look like they did and get genuine builders to come
in.
One last question.
And Chrissy?
Yep.
Part of the talk.
I was curious, what has to be set up on the user side to be able to use the standard?
Like if you are talking about like a completely non-crypto users.
Yeah, great question.
So all you need is a wallet, any browser wallet, embedded wallet, server wallet, whatever
you have will very easily work with X402.
If you navigate to like an X402 blocked URL, it'll just say a button, connect your wallet,
and you just sign a message.
So it's any EIP 712 capable wallet, which is pretty much everything these days, will be
able to very easily interact.
So you can do both humans or agents who are having one.
All right.
Thank you, Lincoln.
Thank you.
I'm going to welcome up Shay from Flashbots.
She's one of my favorite speakers.
And she really puts a lot of work into her talks, which is why she's here at the Bank of
the Summit.
Shay, come on up.
Hi, everyone.
I'm Shay.
I'm from Flashbots, and today I want to talk about the rise of the bot economy.
I think it's clear that software is increasingly replacing the role that people play in markets.
This is what the floor of a stock exchange used to look like, people making trades with
paper slips.
And this is what it looks like now, no paper, one guy, tons of computers.
And I think Wall Street is kind of just the tip of the iceberg here.
You know, memes, predictions, restaurants, concerts, online shopping.
You name it.
Somebody has probably made a market for it on the internet.
And that market has probably been botted by programs that are faster and kind of more capable
of navigating digital markets than humans ever will be.
So I kind of just want to talk about what this means.
And also how we make the most of it.
I think that with the right tools, you know, we can not just handle the acceleration of
bots in the economy, but actually use their unique properties to give people better outcomes.
And I'm going to look at basically free things today.
First, the acceleration of bots.
Second, how to make good markets for them.
And third, why these new markets can, I think, also be better for people.
Okay, starting with all the ways that bots are kind of already running your life, whether
you realize it or not.
The most obvious place, I think, is in financial services.
So as stock markets digitized over the last few decades, it caused this sort of massive proliferation
of bots that were extremely optimized to capture opportunities at low latencies.
And you know, if you take high frequency trading bots, for example, they would listen for retail
trades posted on one stock exchange and race to frontrun them on other venues, sometimes
making these huge profits at the expense of slower human traders.
And bots like these and others have kind of a huge impact on your financial life.
You know, the price you get, maybe the performance of your retirement fund, and they've been
a major source of activity on Wall Street for over a decade now.
And the role of bots in financial services, as you all well know in this room, is only growing
over time.
And recent years institutions have also started to adopt crypto rails to offer services like
stablecoins, you know, payments, tokenized funds, you get it.
And again, if you look under the hood of these new crypto products, you will also find tons
of bots.
Basically, this is actually what DeFi markets look like on Ethereum today.
If you pull back the hood, there are tons of bots involved in executing your trades and
doing really important jobs in apps.
So very briefly, trading apps use bots to sort of outsource routing, lending protocols,
use bots to remove bad debt.
Your favorite wallets also are using bots to refund you when your trades create arbitrages.
So this uses a tool we'll talk about later called an order flow auction.
And basically, as traditional institutions adopt crypto rails, these bots are not just
going to be important in on-chain finance, but in financial services more broadly.
And I think it goes beyond finance too.
There's also a growing class of real world activity that's being financialized and exposed
to bots.
If you live in New York and you've ever tried to make a dinner reservation, you're probably
a victim of the bot economy.
Basically, a lot of restaurants open their books at very specific times on a platform called
Rezzy, and people figured out that instead of just waking up at 6am, you could write a program
that goes and straits the site.
And these bots got really, really good.
They would start wiping out reservations in a couple seconds, making huge profits that restaurants
unfortunately didn't really see a dime from.
If you've ever tried to buy a concert ticket, you are probably a victim of the bot economy.
For those of you who live under a rock, Taylor Swift just finished the highest-grossing tour
of all time.
I think that's the stat.
And there was a ton of demand for these tickets, people started botting them and arming them
for profit.
And the FDC actually started suing people.
There's a whole Wikipedia article just about this part, like not the tour, the bots.
And again, we have this case where bots are coming in.
They're scooping up a very scarce digital asset, and both the consumer and the seller are
getting screwed.
And obviously, Taylor doesn't really need the money, but imagine this happening for
like your favorite niche indie artist out there.
I think it's also beyond this, all sorts of digital assets and markets are being created
every day.
With crypto, you can create markets for memes, for elections, for pre-ipiotraining of
public companies, things that sort of used to be available to only sophisticated investors
are maybe weren't even financialized at all or now available to like millions of people
on Robinhood and pump fun.
And if you have ever tried to buy a meme coin on pump fun, then you know that bots are
a very important role in the price that you get.
TLDR, I think software is eating the world.
Crypto is making it easier to inject markets in our software.
And wherever these new digital markets emerge, whether it's on purpose or sometimes not,
the bots will inevitably follow.
So I think we're kind of at an inflection point here.
Not only are bots operating at, you know, unprecedented scales and more and more parts
of commerce, but their capabilities are also evolving in unprecedented ways too.
You know, we can't really talk about bots anymore without talking about AI.
And obviously AI is accelerating the use of bots and everyday commerce.
You can buy things and chat GPT, you can use agents to perform all sorts of economically
meaningful tasks.
But I think that's not even the most interesting part.
I like this chart.
This is a chart which shows how long a model can work independently on a task without losing
context.
So over the last few years, there's been this like you can actually see exponential.
I'm not making that up an exponential increase in how long models can operate without human
intervention from something like I think five minutes in 2023 to an hour in 2025.
And this, I think, has pretty profound economic implications.
You know, the bots of the past were extensions of people.
They were reacting to human activity like retail trades in the stock market.
But I think the bots of the future will be increasingly decoupled from people.
Maybe we don't submit our own trades anymore.
We just rely on bots to sort of elicit our intents and autonomously execute them in a
market where they're kind of coordinating directly with other bots.
And I think this poses a few really interesting questions.
How do we start creating markets that are designed for first principles for bots?
Not for people.
But then how do we also harness all of that activity in those new markets in a way that
actually benefits people?
As we've seen, it's like very easy to screw this up.
If you just slap some bots on your e-commerce site, they will probably break it.
But I also think there's a glimmer of hope.
I think crypto is a really unique category where we actually see apps using bots on purpose,
surprisingly, to power important things like lending and trading and maybe even improving
prices for retail traders through order for auctions.
So that's kind of what I want to look at next.
Hopefully, I have convinced you that bots are somewhat important at least.
And now I just want to talk about what crypto has taught us about how to make good markets
for them.
I'm going to focus on two things.
First, how you resolve competition from bots and second, how you manage the flow of information
between them.
This is not a complete or prescriptive answer to how to design good markets for bots.
But I did just want to show you some of the tools that have worked for us.
Okay.
Let's talk about competition.
If you remember from earlier, this is what crypto markets or DeFi looks like, tons of
bots competing for opportunities under the hood, liquidations, arbitrages, whatever.
And this is actually what they're competing for, who lands their transaction first.
Ordering is hugely important in financial markets.
If your request gets executed before your competitor, you'll snipe the opportunity.
They'll be left with nothing.
So basically, one of the really important market design questions is how do we sequence these
requests in a way that is, you know, both really fair and really efficient?
Okay.
We have studied this problem a lot at flashbots and I'm just going to give you a extremely
quick crash course on what we have learned through, in some cases, a lot of trial and error.
And basically, there are three answers to them are wrong.
The first answer is latency, just, you know, put the transactions in the order.
You see them first come first serve, sounds really easy.
This is wrong because latency based ordering will inevitably create latency wars where bots
sort of pay huge amounts to co-locate with the stock exchange or the server that's actually
doing the ordering so that, you know, their trade gets seen a millisecond before some
other bot.
And researchers have kind of found that, you know, this competing on latency doesn't actually
improve market efficiency, latency based ordering is a really great way to subsidize AWS
and a really bad way to give people good prices.
Okay.
The second answer is to just make your ordering totally random or blind.
Basically, don't give bots any guarantee about where their transaction is going to land
and this answer is also wrong because if bots can control where they land, they're just
going to spam you, especially when fees are low, bots can afford to hammer you with tons
of speculative transactions in the hopes that just kind of one of them succeeds.
And we have unfortunately learned this the hard way in crypto in the last year, kind
of embarrassing actually half of the gas on top of the other in rollups, whereas I'm
eating by, eaten by spam bots.
And this has like a bunch of negative externalities you might guess, spam sort of congested network.
It raises the price for normal people to transact.
You have to like re-simulate all of these failed transactions in perpetuity, it's kind
of annoying.
Okay.
The final answer is to run an auction, create an explicit market for transaction ordering
where bots can basically compete on price, not on spam or latency.
And you know, whoever pays the most just gets their trade landed first.
It turns out auctions work very well.
A few years ago, we launched an auction on Ethereum L1, it was called MedGeth, where bots
would basically compete for opportunities explicitly instead of hammering the chain
with tons and tons of failed requests.
And this actually dramatically reduced the spam on Ethereum, and you know, these days basically
auctions are used everywhere in crypto apps, trading apps, lending apps, crypto wallets,
all use auctions to resolve the competition between bots and actually channel it into outcomes
that benefit their users.
Modern order full auctions, for example, have generated tons, tens actually tens of millions
of dollars for users to date, tons and tons of refunds.
The way they do this is they run an explicit auction between hundreds and hundreds of bots
that compete to find arbitrage generated by user trades.
And the auction makes sure that the bids from those bots actually gets refunded back to
users instead of just kind of wasting it on fees or infrastructure costs.
Pretty cool.
Okay.
So this is actually what crypto markets look like today.
There are a series of auctions which harness competitive markets of bots to both maximize
the quality of the execution for users and also protect the underlying system from negative
externalities like spam.
Okay.
So yeah, as our former president was saying, you know, mission accomplished, just like use
an auction.
You won't have any problems with bots, right?
No, not quite.
It's not that simple.
The other thing we've learned the hard way in crypto is that it also really matters how
your auctions are designed, and there is one property.
The next thing I'm going to talk about that matters more than almost anything else, which
is this information is the most valuable currency in the bot economy.
You know, who knows what?
And when they know it, if a bot knows you're about to make a trade, they can like exploit that
information to really quickly front-run you and snipe the opportunity first.
This is exactly what happened in high frequency, with high frequency trading bots in the early
2010s.
They, you know, would see somebody making a retail trade on one exchange and race the front
run them on another.
The same problem was also endemic to early crypto markets by default, all pending transactions
on Ethereum are broadcast, as many of you know, to a public mempool, which basically means
you can't make a move without tipping off a whole army of bots that are just like lying
in wait, to front-run you, and this was actually really spooky people kind of compared it to
the dark forest from the trilogy, if you're familiar.
Okay, so the solution we came up with was this.
It was to create what we called private mempools where you could basically submit your transaction
to a third party who figured out, I don't know, wave my hands about how this works, but
they figured out how to pass them directly to a third, to a minor or a validator, whoever
was landing the next block without revealing your transactions to bots in the process.
And basically if you trusted the people importantly, if you trusted the people running these
mempools, it would really dramatically reduce the risk of getting front-run.
Private mempools are a step in the right direction, but the initial implementation is a really
crude solution to what I think is a much more nuanced problem of choosing what information
to share and how in the bot economy.
It's an information flow control problem, not just a privacy binary.
First of all, there's a lot of information that you actually do want to share with bots.
They need to know what pull you trade it on to back on you and order flow auctions.
They need to know price updates to remove bad debt and lending protocols.
Full privacy stops bots from doing bad things, but it also stops them from doing good things,
useful things.
And so really what I think we want is programmable privacy, the ability to selectively
disclose the right amount of information to the right parties at the right time.
This is one thing that I think crypto is really pushing the envelope on.
Modern order flow auctions have actually, in the process of running all these experiments,
we've generated years of production data on how execution quality is affected by quite
literally dozens of different privacy settings, which is pretty cool.
And as we push the limits, I think it's also become clear that it doesn't just matter what
you make private.
It also really matters how you implement your privacy.
What tools you use, what trust assumptions they have, all of these things have a truly
massive impact on the outcomes that people get.
Because when people are selling you privacy, very often they're actually just selling you
this.
They're asking you to trust them to not share your information with somebody else.
This is how early private memples work in crypto is how dark bulls work in tradfi.
It's basically what you're doing if you're like talking to chat GPT as a therapist.
You're trusting open AI to not share that with somebody else.
And the problem with this, specifically from an economic standpoint, is that trust doesn't
really scale.
Trust-based markets are fundamentally bottlenecked on our relationships with a few human actors, right?
Which limits how many parties can compete in these markets to drive better execution
for people.
And if you don't have enough competition in your markets, people lose billions of dollars.
The SEC did a study about this in 2022, which basically found that the lack of competition,
you can't read the fine print, the lack of competition in traditional order flow markets, was costing
users about one basis point per trade, which is something like $1.5 billion a year.
We really, I think, need to reduce the role of trust and get people out of the loop if we
want to maximize economic welfare.
And this is something that I think crypto also has been pushing the needle on, accelerating
the production application of trust minimized privacy techniques in financial markets.
And I'll name just a few really quick examples. This is not not exhaustive.
But crypto wallets and exchanges have accelerated the use of multi-party computation for custody.
You know, instead of trusting a single party to hold your funds, you distribute that responsibility
among a bunch of people in a network.
Chains like Ethereum and Solana have also been recently accelerating the use of secure hardware
for sequencing.
So instead of trusting the operator of a private memple, not to front-run you, you can actually
encrypt your transactions to a secure enclave on a very special type of machine.
And basically, you end up trusting the hardware provider, not the specific operator of that
machine to prevent leaks, which is cool.
We are obviously far from a perfect solution, NBC is slow.
It also introduces weird co-location incentives, sorry, introduces weird co-location incentives
if you kind of play it out.
Secure hardware obviously also has a very big physical attack surface and the supply chains
are hard to audit. But I do think each of these tools kind of brings us a step closer to our
ultimate goal, which is, you know, reducing the role of trust in privacy and making privacy
programmable through software and hardware.
And I think this work is only becoming more important as AI capabilities accelerate.
We're already seeing, I think, like, interesting adversarial behavior with LLMs that's vaguely
reminiscent of the early Dark Forest days on Ethereum.
If you take things like prompt injection attacks, adversaries will basically try to insert
these prompts that cause as your agent to deviate from expected behavior.
And, you know, example, this would be printing out your credit card details when you were actually
trying to book a flight.
It's not a perfect analogy, but I think, again, we're seeing bots use pre-trade information
to negatively impact user execution.
Which kind of raises the same question that crypto apps have been asking for years?
How do you constrain bots without completely handicapping them from doing useful things like
booking your trade or back running your flight?
I think we've, hopefully, as I've shown here, we've started to develop some of the tools
to address these kinds of questions in crypto, you know, with programmable privacy.
We can unlock more efficient kinds of collaboration between untrusting parties with auctions we
can sort of scalably harness competition to drive better execution for people.
These tools were definitely inspired by the challenges we faced running markets for
bots like front-running and spam, but I think they're not just mitigations.
These are just tools for general purpose tools for building new markets that gives people
better outcomes, which is, I think, kind of what crypto is actually about.
So to close, I just want to talk a little bit about the opportunity ahead.
How with crypto, the bot economy could actually be better than what came before it.
Okay, we will start with some low-hanging fruit.
If you want to make restaurants and notoriously difficult business, you know, more profitable,
don't ban bots, get ready to use an orderflow auction and share the profits back to the
restaurants.
Do you want to stop bots from racing to scoop up tickets before normal people can buy
them?
Maybe we try running an explicit batch auction for the next Taylor Swift tour.
If you don't believe me, just, you know, as the SEC, they actually, after they ran the
study, we talked about they proposed a rule which would require trades to be read it
through a competitive auction, a fun fact.
Okay, basically, almost any time you have a scarce digital good, whether it's block space
or ticket sales, I think you can use an auction to both better handle and internalize the
competition, the welfare that the competition generates.
And as we, you know, remove tickets, humans from the loop, I think we can convert more and
more activity in these markets to auctions.
So one example here, I think this is pretty cool.
Actually, human psychology makes pricing pretty inefficient.
This is a fun example.
You know, you and I have a very high transaction cost.
We like to know exactly how much something is going to be worth before we buy it, which means
that if you look online, like most sales are fixed price.
But a fixed price is rarely the most efficient clearing price for a market.
And if your market is friendly to bots, you can basically just start running just in time
auctions for every digital good you want to sell.
I think that could be cool.
And just as auctions, I think are not just about presenting spam, the privacy tech we talked
about earlier can do more than just prevent front running, take advertising as an example.
One of the biggest digital markets in order to curate relevant ads, you need a lot of sensitive
data about both user behavior and advertiser preferences.
And right now people basically have to trust auctioneers like Google with all of that information.
And imagine just as an experiment that you ran your ad auction in secure hardware.
This could actually improve privacy for users because they aren't revealing personal data
to third parties like Google.
It could also prevent the auctioneer from tampering with the logic, which Google was sued for
doing a little while ago.
And it could actually open the door to these really interesting new mechanisms.
Imagine if instead of sending static bids as people do today, advertisers could just like
send programs that dynamically adjust their bids in response to sensitive data about users
that's only available in the secure enclave.
There's a very cool paper on this if you're interested.
But basically the bottom line is I think just by using different technology like programmable
privacy, we can get both better ads and more protection for users instead of sort of
trading one of those things off for the other.
And I think that's really one of the core competencies of crypto, creating new coordination
tools that turn zero sum games where you have to sacrifice one thing to get another into
positive sum games, where we can kind of fulfill seemingly conflicting goals at the same
time, you know, privacy and efficiency, for example.
And speaking of coordination tools, there's just like one more thing that I want to leave
you with.
Consider the classic problem of two self-driving cars going in perpendicular directions.
If they only optimize for their local goals, they're going to crash, but if they coordinate
through a device, like a traffic light, that lets each car credibly commit to stopping
for a period of time, then they can kind of escape this prisoner's dilemma.
And what is a blockchain, if not the sort of ideal programmable, bot-friendly, credible
commitment device?
Zooming out, I think as softreads the worlds and agent capabilities grow exponentially,
there will be more and more games to play.
And I think it's up to us in crypto to build tools like auctions, programmable privacy,
reliable commitment devices that can turn those games positive sum.
We are still very early here, there's a lot to build.
My guess is that we're probably going to need a plurality of different solutions.
You know, the bot economy, as I hope I've shown you, promises to be massive.
So the question, in my view, isn't, you know, if my favorite privacy tool is better than
your favorite privacy tool, but rather how do we get more people building both of them?
So if this interests you or you want to learn more, I hope you will come join our collective
of researchers and developers who are working on these problems.
Thanks.
Thank you, Shay.
Shay, do you have time for a question?
So it seems that the auctions are solution to everything, but are there any examples where
auctions don't work?
Samples are auctions don't work.
That's a fun question.
I mean, to be honest, I haven't really come across a good example at scale in the markets
we work with.
People, there are lots of cases where people don't use auctions because they have like certain
preferences.
Maybe, I think maybe a good example would be in, you know, traditional stock exchanges.
They've like really optimized for latency based ordering and there's probably some reasons
you might want to do that.
Maybe they're just like historical reasons why this is how your system is built and you're
kind of optimizing for what you have, but at least in these like new digital kind of
crypto markets, we have really not found a good example where you don't want an auction.
Yeah.
Thank you, an auction, Maxi, maybe, I don't know if I want to publicly commit to that,
you know.
Okay, thank you so much.

All right, so I talked a lot about networking and I'm going to talk a bit more about this
computation side of scaling Ethereum for the next 100 times.
So hello everyone, I'm Michael, I'm a founder and CEO of the brevis, but today I'm not going
to show too much about the brevis itself, but I generally talk about how we see the future
of Ethereum scaling dependent on the concept of zero knowledge proof.
So you know, first, I just want to say that OK, OK, blockchains, especially really kind
of decentralized later on, blotchings like Ethereum is often adopted as a water computers,
but the reality is that it cannot run faster than a single server and it is fundamentally
extremely expensive.
You might say, wait, wait, wait, wait, so we have all these kind of performance optimization
scaling solutions in the last decade, you know, we should be able to just run anything on
Ethereum or kind of a layer one, blotchings it today, right?
Well, you know, unfortunately, that is not the case.
Let me give you a very, very simple example.
So let's say, you know, you guys probably all use a centralized exchanges and in every single
centralized exchange, you always have this very simple future feature that if you trade
a lot in this month, you got to feed this content in the next month.
So you know, this feature is great, it gives you know, the exchange retention, boost volume
and boost the revenue bottom line.
But if you look at every single decentralized exchange today, none of them have this feature
until very recently.
Well, why is that it's not because they don't want to add this kind of a user experience
customization feature.
It is because that even to compute a user's historical trading volume on chain is actually
extremely expensive, even on the cheapest layer to you can find today.
So the reason this basically shows us that there's a blotching as a, you know, a kind of
computing solution is still kind of fundamental element of the interface of cost and, you know,
processing capability.
Now, you know, why is that?
Well, the reason is actually pretty simple because today's consensus is built on a very,
very simple form of computation.
So let's say, you know, we have Alice and Bob as two nodes in a blockchain and what consensus
is trying to do, you know, this is like simply oversimplifying the entire networking stack.
But what the consensus is trying to do here is to basically say, OK, Alice has done this
computation to say, OK, you know, I get the, you know, result of the multiplication equation,
you know, what Alice is trying to do here is to reach consensus with Bob, which is letting
Bob agree that it, you know, he can arrive the same answer.
Well, how can Bob know if the answer is correct or not?
The simplest thing, which is like the simple form of computing Bob can do is to just repeat
the same computation again.
So now, you know, we have two nodes and we repeat the computation two times.
And today's consensus is built on this concept of reaching consensus by recomputed notation
as a master of verification.
Now that is precisely the problem.
Let's say we're doing a kind of a swap computation on a kind of a decentralized exchange.
What's actually happening in the internet where it's not one node is doing this computation.
And in fact, like in Ethereum, for example, you have millions of nodes that is doing the
same exact computation again and again and again.
And this is a fundamental reason why, you know, blockchain at computation are expensive
resources.
Now, we have a good solution, however, to solve this.
This is a new concept of the verifiable computing.
So in verifiable computing, let's look at the same two node blockchain here.
You know, we have different roles in the entire computation process.
The Alice here becomes something called a prover.
So instead of just doing the computation itself, Alice in addition, compute something called
a zero knowledge proof.
This zero knowledge proof is a very magical piece of a mathematical, you know, cryptographic
thing that she can use to send it to anyone.
And this other party can simply verify, okay, the computation is, the computation is actually
done correctly without redo the computation again.
And you know, the important thing here is that the verification process of the zero knowledge
proof is extremely low cost and low latency.
So you know, this kind of a new paradigm fundamentally decouples us, you know, sorry, decouples
the computation itself from the verification process.
And very nice property about zero knowledge proof is that no matter how complex your original
computation is, you can always compress this very complex computation down to almost exactly
the same kind of proof that can be verified with almost the constant time with the extremely
low latency and low cost.
So, you know, so now you may ask, like, wait, wait, ZK, we have been hearing about ZK for
like, you know, ages as well, but why now, like why we couldn't do this before?
The key thing here is about the blue, like kind of a blue computation cost here, you know,
a couple of years ago, like even just two years ago, the difference between doing the
original computation and generating a ZK proof of arbitrary computation, the gap of that
is about a million times.
So what this means is that, you know, if you're doing this kind of thing in a verifiable
computing way, you're not even better off, you know, than just like doing the replicated
computing.
You're basically kind of repeating the same kind of a computation about a million times.
But the key thing here is that, you know, over the last couple years, and especially this
year, we have achieved so much progress in ZK, that this gap between the original computation
and the proof generation shrinked by orders and orders of magnitude.
Now we are about a hundred times to a thousand times, you know, kind of a, you know, inflation
comparing to the original computation if you run the computation in ZK.
And this becomes extremely useful because instead of replicating this for a million times,
you can just like spend a thousand more kind of a computation and gave like the same kind
of a computation result to everyone.
So roughly speaking, this is like the kind of a innovation that enables this new trend
of zero-nage proof and how it can help Ethereum to kind of achieve the next hundred times
scaling.
So you know, what we build at Bravis is we build this kind of a solution that has a very
generalized a smart, verifiable computing platform that allows you to awful, very complex
computation away from blockchain to the off-chain box called Bravis.
And Bravis will generate a proof for that and then kind of send the proof back to the
blockchain.
So the blockchain as, you know, using kind of as a validator or as a blockchain as a whole
as a smart contract, can just verify the computation easily with low cost and low latency.
And then use this combination as if this actually is done on blockchain from the beginning.
So, you know, just want to mention that as I mentioned, this is this technology is very
used for future for future of Ethereum scaling, but you can also actually use this in your
application today.
So we're powering numerous different applications now in various different sectors, like in, you
know, Metamask, for Uniswap, Perthankxwap, for many open-eaten euro money, all these stable
tokens, lending protocols, you know, and perp taxes and all these to enable them to build
a new generation of features that is not possible before due to the constraint of the current
later ones scaling.
But let me go back to kind of talk about the scaling, you know, itself.
Now, you know, we say, okay, this is a new paradigm of computing, using verifiable computing
and, you know, what is actually inside of the magic box?
Well, you know, the centerpiece of this entire kind of verifiable computing stack is generally
a ZKVM.
So for us, this is something called a pickle ZKVM.
So the interesting thing about, you know, a ZKVM comparing to your general ZK circuit is that
it is built on a very general instruction set.
So you can actually run, in theory, any kind of software you want to run in this without
actually needing to understand the integrated details of the, you know, zero large circuit,
you know, development.
So this is just a comparison for the same kind of a program.
If you write it in your own ZK circuit, it's going to be this complex.
And if you write that in the, you know, in kind of in ZKVM, you're just essentially writing
Rust.
Now with this kind of a new developer friendless, you enable something that is very powerful.
That is essentially you can write a theorem, a kind of full execution node.
The, you know, you can just rust and then run it and kind of in a entirely verifiable way.
So this is how we can now use generalize the ZKVM to change how Ethereum layer one consensus
works.
Now, instead of, you know, we pack one block, you know, a broadcast block in every, everyone
kind of verify the block execution through recomputation.
Now what you can do is that you have just one node that is running a computation itself
and then generate a ZK proof and broadcast a ZK proof, which is a very succinct that fuel
bytes, you know, proof to the entire network and everyone every validator in the network
just verify the proof with extremely low cost.
Now the challenge, however, is that you know, you need to have that performance and, you
know, to be kind of fast enough.
So you can generate the proof with the same kind of a latency that Ethereum is running
on today, which is like a 12 second block delay.
And this is why, you know, you probably heard about like a lot of kind of a push and movement
on something called real time Ethereum proving that it's like once a Ethereum block is produced,
you need to generate a proof of the execution correctness within 12 seconds.
So you can actually broadcast this very, you know, proof to everywhere and in fact, like
the age, it should be like less than 12 seconds, you know, it should be 10 seconds because
of the additional kind of overheading networking.
Right.
So this is like why we're pushing forward and, you know, pushing the boundary of a zero
and a proof to achieve something called real time proof.
So pickle, you know, which is the ZKVM that we build already achieved this, you know,
with 64 GPU, we can achieve average proving time of 6.9 seconds, which is a more than enough
to actually enable kind of a new kind of a consensus client in Ethereum today.
And, you know, so there's like this kind of a layer to, you know, beat equivalent, which
I would invite you guys to follow, called esproof.org.
And you know, it shows that the different performance of a different kind of a ZKVM's for, you
know, Ethereum scaling specifically.
And the important thing I want to highlight here is that it's not only just the causes
going down, but the prior time of the verifiable computing, especially for Ethereum and layer
execution, you know, has really changed because now, you know, we can do parallel computing.
Essentially, you have like a big block, right?
So like we can actually chop the big blocks into smaller blocks called subblocks and run
these kind of a computation in parallel.
And once we have this kind of a capability, you essentially convert the Ethereum scaling
problem itself also into a pure problem, a pure money problem, which was never possible
before.
So if you want to scale Ethereum by 100 times a day, right now, what you need to do is to
just throw more GPU resources into the proving stack, and then you can essentially generate
a proof, which is still very succinct, the same level of verification costs.
But for a block that is 100 times bigger, you can do it today now.
So this is a major breakthrough that we can actually convert the problem space entirely.
And you know, this is what what I just talked about is that, you know, how you can essentially
kind of scale Ethereum by replacing the consensus process as a, you know, computation paradigm,
but we should also look at the application layer as well, you know, how you can scale the
Ethereum application using the same kind of a paradigm because even if you scale up like
Ethereum kind of a by 100 times, you're still looking at a single straight at the machine,
which cannot run faster than a single server, right?
So Pico is fast, as we know, but, you know, how we, you know, it is not fast enough because
like we know Pico is very generalized, you can build any kind of application on top by
just writing high level programming language code.
And you know, how do we kind of achieve the best of the tour?
Well, this is the innovation that we introduced that is like we need a really modularity in
the entire verifiable computing stack to treat the VM as just the glue of the computation.
And then allow is to actually get a lot of plug-ins to enhance the capability for different
kind of applications and errors.
So for example, you know, the example I mentioned like a computing a VIP trading fee discount
using zero large proof.
You can essentially build something called a on-chain Zika data co-processor can sign up,
which can significantly accelerate the performance when you're dealing with use cases that
involves on-chain historical data computation and Zika proof.
So and, you know, you can of course also enable things like Zika TOS that is like, you know,
you want to essentially compute what is, let's say your, you know, coin-based trading volume
in the last months, you can essentially say, okay, I'm going to run a Zika TOS co-processor
to first get the raw output from my coin-based account, but I also want to run a computation
on top of it to derive some interesting and the informative data that I can use to prove
that, hey, look, I have traded more than one minute, but at the same time, hide important
information such as your exact kind of token trading and the, you know, the details of
your entire trading trace.
So this new paradigm of kind of a, you know, building a verifiable computing stack with
the ZKVM as a center glue and many kind of different application level co-processor is
something that we really want to promote as well.
So this is precisely the reason why, you know, Bravis itself has so many different use
cases across so many different, you know, domains in the application space as well because
we have the capability to do this.
So some very simple examples that I want to mention here, you know, we, for the, for the
kind of the VIP trading user experience customization example, we already powered this with pancake
swap.
So if you, you know, swap a lot in the past, you can essentially generate the ZKVM proof
to show your big trader VIP trader.
And then, you know, on the flight dynamically, your trading fee will be decreased because,
you know, you actually kind of show that, you know, you're, you're kind of a different
trader than the other different users.
And this feature has worked great because, like, you know, as we see, we can provide more
efficient market structure and, you know, essentially give like better profitability for
the LPs and also like much better liquidity efficiency as well.
And, you know, so for the previous example, you know, you have kind of some of the logic
that still lives on chain, but some of the logic, such as the user experience customization
that is living off chain.
But what we believe that a future kind of a, you know, verifiable computing application
architecture will look like is that most of the computation itself is going to happen
in an off-chain world.
So you can essentially now have a ZK-powered perpetual DAX system that the matching engine
itself is living off-chain as a verifiable computing component.
And all the matches and all the trades can be verified and committed back to the Ethereum
layer one blockchain.
And then, you know, at the same time, what you got because you were using ZK is additional
privacy benefit to say, okay, I can actually hide, hide some of my orders that I want, don't
want to kind of everyone to see to avoid liquidity assassination, a liquidation assassination
that we see in many existing protocols.
We're actually building with one of the world leading perpetual DAXs for this on this
and, you know, releasing this very soon as well.
So you know, another kind of a benefit of a ZK as we kind of a transition in this entire,
you know, computing stack into verifiable computing is a benefit of privacy, right?
So we recently launched this new feature with KIDO that allows you to attest to your
on-chain historical data, such as, okay, I'm a big holder of certain tokens, therefore,
my yapping should have like a higher weight in the entire ecosystem, well, you know, but
at the same time, I don't want to reveal what exactly is my wallet address.
Now you can actually use brevets to generate a privacy preserving a task station to show
that you are actually this kind of user without revealing any kind of detail of your wallet.
So this, you know, ZK, you know, solution not only can be used as a scaling solution, but
also in many cases can bring additional privacy benefits.
And, you know, there are so many others that I probably don't have time to talk about,
but, you know, just another very big category of use cases is how you help the stable token
and real world asset ecosystem to grow and also the chain itself.
So let's say you launched like a real world asset, you know, and the stable token, you want
to kind of actually have your entire stable token used by all these different awesome
DeFi applications. And, you know, the next thing you actually need to do is to run a rewarded
system or kind of reward distribution protocols to help user to actually use your stable token.
And what we enable for these different kind of stable token protocol is to allow users
to generate a zero knowledge proof to show that, okay, I actually deposited my stable token
in this DAX.
I deposited in my stable token in this kind of a landing protocol.
And therefore, I should be getting this amount of, you know, kind of reward from the protocol.
So they can have a fully transparent secure and at the same time compliant, you know, protocol
reward distribution system that was not that was not possible before.
And we did the same for linear recent launch, where the one that is powering the entire
linear token distribution program called linear recognition through Zika Proof as well.
So my biggest prediction here is that, you know, verifiable computing because the cost reduction
and the advancement that we made in the last couple of years is going to actually take
over 99% of the computation for all blockchain applications in the next, you know, 10 years.
And, you know, we're actually rapidly approaching towards that as you said, as you saw, like, you
know, I showed some of the kind of approving and the performance numbers using 64 GPUs.
We can today actually achieve the same level performance with just the 16, you know, this
is just like a, you know, kind of a couple of weeks gap between me making the slides to where
we are now.
So, you know, just kind of as a closing thing that is, you know, for brevis, we have a full
stack ZK computing stack, as I mentioned, as with the pickle ZK VM as a glue and different
kind of a co-process to handle different application use cases.
And we recently also announced a prover nut that allows you to match different kind of
approving requests to different kind of approvers to optimize the entire proving flow with
high availability and decentralization.
So yeah, with that, that concludes my talk and, you know, thank you for.
Thanks for who's got a question, who's got a question, question down here.
All right.
Thank you.
Yeah, really, really an incredible project and great presentation.
It seems to me like brevis could become pretty critical infrastructure.
I'm just curious about what your, at liveness guarantees are.
So if the proven network holds what kind of backup options are like, I'd be just curious
for you to talk about that.
Yeah, so, as I mentioned, I didn't want to kind of show too much about brevis specifically,
but the proven network is specifically to solve the liveness problem that you mentioned.
So like, you know, the idea here is that you need to open, you need to open marketplace
to match different kind of application developers, proving needs with different kind of approvers.
Some of these are required like a launching ZK data co-process or some of this requires
like a ZK TRS co-processor, some of these requires like full block execution.
So you really need to have like open marketplace where different type of approvers can actually
participate in and be matched with different kind of application needs and application
requests.
So, you know, so this kind of thing is actually very, very hard to solve, you know, mechanisms
and design game theory problem that we actually specifically designed something called a
truthful online double auction to, you know, do this kind of a real time rotating auction
that allows you to kind of express your proven needs into different chunks and replicate
them if needed to kind of maintain extremely high availability and you know, high liveness
essentially.
So, that's how you can essentially solve this problem.
All right, coming up next, I'm sure all many of you are at least paying close attention
to all of you and the story of money is very dear to the, to my heart, to my heart, to the
whole story of bank list.
So, next up, I want to invite Luca Prosperi from M0 who's going to tell us a little bit about
money.
Luca, come on up.
This, this talk is going to be theoretical by design, but I think it was important during
this conversation, during this conference, to point the finger on some of the weird things
that are happening in crypto, meaning we're spending so much time thinking about the structure
and the design of the networks we operate on from a computing perspective and we spend
zero time thinking about the financial layer that is actually powering most of them and
the, the single point of failure that stablecoins are actually creating in the ecosystem.
And as we know, like the definition of money typically goes like this, like, you know, what
is money?
Money is a unit of measure.
We measure the things we do in monetary terms.
Money is a store of value, how we can keep, we can keep the value we have, but this is a story
of the explosion of Bitcoin and stablecoin and Argentina.
Mariana was talking about, and money is a medium of exchange, needs to be easy to transact.
Now, this, like the concept of money has been abused a bit in crypto because we created
yield products that look like money, but they're not and another, and other things around.
So the finance people go a bit deeper and say, okay, what is actually good money?
And this is, this is from one of the, I think the best papers about money, money, monetary
policy I've ever known by OMSROM and said that money actually, the second paragraph is,
money is to be easy and liquid.
No questions asked.
You actually need to send it around.
You don't need to worry about how collateralized it is, what is the value of it, how you can
trust the person, needs to be easy to transact.
And this is proven right for the USDT, USDCs we know about, right?
They kind of work, you have it, you own it, and you can use it to transact on chain and
off chain.
But in my opinion, this is a very limited perspective of money because in my opinion, money is
a network, money is a network that connects everyone and groups of people, companies, and currently
this network is running on another network that is the set of blockchains that we use every
day.
And networks have shapes, so there are networks that are shaped in different ways and the
shape of a network has some pros and cons.
And we should think about it because we are impacted by those pros and those cons.
So what are examples of those networks?
So we have centralized star networks, and this is the way the banking system works today.
You have the central bank at the center, is creating assets, is creating monetary value,
and is pushing it downstream through commercial banks and commercial banks of clients.
So you do not have an account of the Fed, you have an account at Barclays, which is BC,
JP Morgan Chase, and those guys have an account of a central bank.
So if you're cut out by a bank, you're out of the system.
Then we have distributed match networks and people here, they might recognize the Bitcoin
network where all the nodes are connected with each other and there is not single node
that can cut anybody out of the system.
Obviously, this network is a different characteristics from the previous one.
So the previous one, the previous one, for example, is impacting the accrual of value
at the center, who makes money in the dollar network is the US government.
The US government finances itself very cheap.
You don't make any money on the US dollar.
You get the benefit of the fungibility of the system, but the value accrues at the center.
In the Bitcoin network, the value accrues based on time.
If you were early in the Bitcoin network, you have accrued a lot of value.
If you're coming now, the value accrue just to reinforce the network is lower.
So you can see how the topology of the network, the shape of the network, is impacting certain
things of the network itself like value accrual.
So what are the examples of monetary networks that we have today?
We have centralized and concentrated networks like the stablecoin networks today.
You have circle, you have tether, and at the center you have the blockchains which are distributed
systems.
If we are spending so much time about the decentralization of blockchains, if tether blows
up, we're all fucked.
If circle cuts you out because you, they blacklist you, we are all fucked.
So we spend so much time thinking about how important it is to have distributed systems
where we transact, zero time thinking about the single points of failure that we have at
the center, at the level of the issuers.
So surprise, surprise, who makes the most money?
The guys want to mediate in the value.
You have dollar packs decentralized networks.
And this is the word Mariana was talking about, the previous bull market word where you
had circle, you had maker was a decentralized stablecoin issuer that was somehow connected
through circle through a thing called the PSM that was provided stability, but it was
more decentralized and who was making money in the maker ecosystem was not necessarily
a single issuer or more parties.
You also have now starting to appear consortium like federated networks where you have the
taxes, the anchorages, the bridges, saying you can issue through us many types of stable
coins.
Still, it is an attempt for them to position themselves to a cruel value.
Most people will have given a lot of respect for a striped team, but most people will get
the irony of striped creating open networks within striped.
You also have digital, you, you might have in the future, digital native and distributed
network.
Okay, maybe we are still using the treasuries to back our money, but the treasuries issued
in a decentralized manner on chain, like hopefully on Ethereum.
And then you have systems that exist already on chain that is still giving a lot of power
to the US government, but the rest of the value of cruel is distributed downstream.
And then the holy grail, you might have fully distributed issuance and authority networks
where you have different assets that are composing our store of value and monetary use cases.
And you know, the value is actually distributed around and there is not anybody just capturing
most of it.
This is hopefully the future we're going into.
Now, does the monetary topology matter?
We touched on this earlier, it does a lot because impacts certain characteristics of money.
And I am convinced that people do not really pay too much attention to it.
Not only us, the users, but also the regulator.
You have so much time, you hear so many times the regulator thinking about whether a stable
coin is collateralized, is not collateralized, is well designed, is riskier, but do regulators
ask themselves how the networks of money are shaping up in the future, probably not enough
and they should.
Because the shape of the network is impacting three main things.
Value extraction capacity, as we said before, who makes the money, and you can rest assured
that those who make the money, they will lobby to tell you and convince you that the way
the network is is the best only possible way, but in crypto, we don't take anything for granted.
How is the quality of the communication spread around the network?
How actually the pricing and monetary policy is spreading around the network?
And how resilient is the network?
And these are three components that are all important and there are trade-offs.
Now, I am a mathematician, so I am a math nerd.
The good thing is that you can actually measure those characteristics for monetary networks
in the same way you can measure characteristics of blockchain networks.
So you have, for example, what is value extraction is the ability of certain actors to extract
rent because of their position from their periphery, the users.
Cether doesn't share the yield. They are the most profitable company in the world.
We're using it and we are benefiting them because there are benefits for us from a usability
perspective.
Now, in graph theory, you can measure this based on the centrality of the nodes.
There are many measures you can do it and I'm not going to spend too much time on it.
But for example, node centrality in between the centrality is a measure that graph theory
is the mathematicians use.
So like you see, for example, a score that is based on how important is a node to actually
intermediate all the communications in a network.
So node number four at the center as the score that is way higher than node number nine.
So you cut out node number four and you're just creating a lot of impacts for the network
and you can rest assured that node number four is making money out of it.
So do we spend time rebalancing those cores and those positions or not?
Probably we should spend more time.
Signal communication is also important.
So what is the efficiency and fidelity of the information?
And again, graph theories can measure this also currently in stablecoin land.
So you can quantify by metrics like the path length, the diameter of the network, how long
it takes to go from node one to node and this is an example.
So in a centralized star network, if you are at the periphery of one, to go on the other
side, you have to go through a lot of hoops and every hoop is creating noise in the, I
don't know, in a decentralized network or in the Bitcoin network, you could actually go
from person to person pretty much directly.
And so it is a bit more cumbersome to build, but the signal for the periphery is getting
higher quality and ultimately resilience.
So how robust is a network in case there are single points of failure?
And this is all blockchains are all about resilience and finally enough, we never asked about
the resilience of the monetary network we use.
So what actually how can we, how can we measure it?
And you know, so one of the main measures is vertex hedge connectivity.
So if you in a star network, you kill the center point and then you're isolating to subsystems,
but the system doesn't talk to each other anymore.
And as in a mesh network, it's very difficult to cut it out.
And these are just examples of way you can actually look at the network from a, from a resilience
perspective.
So everything has a trade off and you, you can see, I put here on a list, the networks
we quickly discussed and you can see the current network we have, it's pretty good on signal
quality.
It's not a lot of price variability on a USDC and USDT is pretty bad on resilience.
If tether goes down, I don't think there is so many, there are so many places to hide.
And I'm not going to say I'm not saying that these guys are going down necessarily at all.
I'm just saying that the single point of failure is a real risk.
And value extraction is very high, there are only very few people, very few institutions
that are making most of the money on the assets that we're using on the rails.
And you can see how these things evolve and it's a trade off.
Like you can go, you can reduce the, you can improve the resilience, you might impact
negatively the signal quality, but it is an evolution we all need to go through.
And ideally the dream is to have max, max, there is, there is a type is obviously minimum
value extraction, there is minimum value extraction, max signal quality, max resilience.
In my opinion, it is a challenge we should take on for next 10 to 20 years, for not having
the risk of very distributed computing systems, but still very, very centralized financial systems
that we tend to ignore.
So I don't have silver bullet on this, obviously, as one of the founders and the CEO of the M0
project, we built the project to create distributed monetary system.
We come from the ethos of the maker ecosystem as well, but I just wanted to stress the point
here, especially in this conference, how important it is to look at monetary networks in the same
way we're looking at computing networks.
Otherwise, we're just over optimizing one layer of the stack and we are completely ignoring
the type of systemic risks and an even distribution of profits that we are, we are living for others.
If we have, if we keep going this path, creating, creating DeFi would simply mean allow all school
regulated financial institutions to open branches on chain, we're just making their, their, their
job easier.
And although we see so many institutions and so many traditional financial players like
like Stripe, like GP Morgan, like the, the asset managers getting very, very involved
in a blockchain, a DeFi, we should never forget that we are not here to actually make the,
the job of Wall Street easier and making Wall Street banks able to sell their products across
the world without intermediaries.
We want to make our life easier as users and owners of the value that we transact.
So I hope we all spend more time in thinking what type of future we are designing for our finances
and just not blindly using the products that are easy to use nowadays, but thanks a lot.
Beautiful, Luca, we have time for a few questions.
One thought that comes to mind, Luca, something we've referred to on bank list is the cantalon
effect.
And I think there's a relationship between the topology idea of money and the cantalon
effect where the central part of the topology is where money issuance happens.
And then as you get further out to the periphery, the, the effects of cantalon effect take over
where the value of the money dissipates by the time it gets to the margins.
And it is local in the center.
I think that's a very relevant story for Argentina as well because the story of inflation
is synonymous with the story of Argentina.
We've got time for a few questions.
Got one right here?
Completely agree with your talk.
Do you think we can do even better than the last slide you showed because you still have
basically the treasury and like Bitcoin, which you can't really have Bitcoin under Ethereum
blockchain without wrapping it, so that's a point of failure.
And then the US government is obviously a point of failure for treasuries.
And also the peg itself is somewhat a point of failure if that makes sense because you're
lying on the Fed to not hyper inflate or do anything like that.
So I know projects like Rye, we're trying, but do you think that's actually like it you
will go to have just eats and then not even have the peg to the US dollar, something like
that?
Yeah, I think this is a multi-dimensional problem.
I think that is a spectrum.
We will go further and further in decentralizing the sources of value that we are considering
a trustful and we consider the US government a source of value.
And so it is a spectrum.
I think it's also a spectrum of how we are, what economy we're living in.
I don't think that, I mean, the US government loves the idea of exporting, continue to export
the dollar across the world, but we are not living within the US monetary system all of us.
So I think that these two phenomena will go in sync, meaning that the monetary system
that we are living in will expand will become way more global.
So also the pegging how we are measuring our purchasing power will expand, it will become
more like a basket, a basket of a basket pack rather than a single one.
So in my opinion, the these two phenomena will just go naturally in sync.
We will have different sources of trust as base assets.
So today is the treasury government, the US government in the future is going to be US government
decentralized assets, private assets, but also the way we are indexing how we are measuring
it will change because we are not all living in the US and for as much as the US will like
it, this is not the only relevant currency in the world.
But the interesting thing is that we are now, this is possible, this is happening.
So in my opinion, it's just how quick we are we are getting there.
One more question right here.
Yeah, how much of the returning crypto is a function of counterparty risk seems that a
lot of people are getting returned just because they're accepting counterparty risk and
not because of any alpha being generated.
And that's why Tether makes so much money because people view it as having very little counterparty
risk.
So the the senior agent counterparty risk is the story of money as a whole.
He's not a crypto story.
You accept dollars in transactions because you don't want to run the counterparty risk
of your, there's no price discovery in monetary transaction.
So it's not a crypto history, it's a money history.
I don't think it's very different.
Now, there are different layers of counterparty risk that crypto can definitely reduce.
And that's why, that's why defy works so well.
So I think that there is, counterparty risk reduction is a huge component of the use
of stablecoins, but I don't think it's very different from any other type of money.
It's the whole question of money.
Like you don't ask questions in terms of credit risk and counterparty risk where it's coming
from.
You're paying me.
I'm fine.
Now, there is risk doesn't disappear.
So we are all running Tether's counterparty risk or circles counterparty risk.
And I think many of us have lived through the Silicon Valley bank days, at some point,
we didn't even know whether the counterparty risk we had was real or not.
So I think this is a history of money in general.
Thank you, Luca.
Round of applause for Luca.
