Transcript
- 0:00You've had a dynamic where money has become freer than free.
- 0:10You talk about a Fed just gone nuts.
- 0:13All the central banks going nuts.
- 0:16So it's all acting like safe haven.
- 0:18I believe that in a world where central bankers are tripping over themselves to devalue their currency,
- 0:24Bitcoin wins.
- 0:25In the world of fiat currencies, Bitcoin is the victor.
- 0:28I mean, that's part of the bull case for Bitcoin.
- 0:31If you're not paying attention, you probably should be.
- 0:36Welcome back to Austin.
- 0:37It's great to be back.
- 0:39I saw you walking down First Street Congress,
- 0:43heading over to Veracruz like nothing had changed.
- 0:45Nothing had changed.
- 0:46I was coming up Congress, you were walking down,
- 0:50you were right where you were headed.
- 0:53I got a walking meeting in, as I was describing to you earlier,
- 0:56around Town Lake today.
- 0:57it was
- 0:58felt good to be back
- 0:59I haven't been gone that long
- 1:00it's been two weeks
- 1:01yeah
- 1:01feels like a
- 1:03you know
- 1:04like you were
- 1:05on vacation or something
- 1:06yeah
- 1:06and I have been leaving
- 1:07for the summers
- 1:08yeah you do spend the summer
- 1:09on the shore so
- 1:10yeah
- 1:11it does feel good to be back though
- 1:12it is weird
- 1:14staying in a hotel
- 1:15we're gonna need to
- 1:15find some way to have it be
- 1:17fairly regular
- 1:18I think it's gonna be
- 1:19fairly regular
- 1:20regular
- 1:21how many
- 1:22times per day
- 1:24do you think you're gonna eat
- 1:25veracarees while you're here
- 1:26I'll probably have it tomorrow
- 1:29I'm going to skip today
- 1:30I'm going to go get lunch
- 1:31for Ryan Gentry after this
- 1:33I think
- 1:33we may do something
- 1:35in the proximity of
- 1:36of the park
- 1:37got your steps in
- 1:39got 20,000 steps in already
- 1:41we did the long route
- 1:42in Town Lake today
- 1:43which I've never done
- 1:44I feel like missing the lake
- 1:45is probably going to be
- 1:46the biggest adjustment
- 1:47you have the shore but
- 1:48we have the beach
- 1:49we've been walking
- 1:50doing push-ups
- 1:51and air squats
- 1:52on the beach every morning
- 1:54which has been good but
- 1:55once you get back to Philly proper, it's hard.
- 1:58We do have some parks around us, but
- 1:59I'm going to try and keep the walking up.
- 2:02Dr. Jack Cruz is really
- 2:03in my mind. Get the sunlight, get the steps.
- 2:05I was at the park. We were at the park on Sunday, and we saw
- 2:07Katie and Mike,
- 2:09and they were talking about SunMax
- 2:11and just kind of happened to see them.
- 2:15That's inspired
- 2:15me to start. And I've been
- 2:17paying attention to Jack for quite a while
- 2:19now, but it's time to put
- 2:21that into action. It is. The sun.
- 2:23provider of energy. I told Kaylee she was wearing sunglasses
- 2:25like hey Uncle Jack says
- 2:26bad for your eyes. I felt good
- 2:29because I didn't know sunglasses were bad until
- 2:33like two or three years ago. Bad for your eyes
- 2:35but I naturally just
- 2:36discarded sunglasses like ten years ago
- 2:39because I would either lose them or they'd never stay on my face
- 2:41and so I've been sunglass free for a decade.
- 2:43I have been as well.
- 2:45Alright.
- 2:48Catch you back in the studio?
- 2:50Back in your studio
- 2:51This is, you're in the interview seat.
- 2:54Maybe.
- 2:55What are we doing here?
- 2:57What are we doing here?
- 3:00Starting a show as part of TFTC on mining and energy.
- 3:07Yeah, not just mining, but an energy focused podcast,
- 3:11a cross section of Bitcoin, Bitcoin mining and energy.
- 3:15And a lot of the inspiration of it has been,
- 3:20just me increasingly focused on the fact that mining is consistently talked about as a point
- 3:27of centralization and it's a really interesting subject on the energy side i think that the
- 3:34energy side of bitcoin is as much of a rabbit hole as money is a rabbit hole and you know at
- 3:43zap right working on bitcoin payments it's not you know the my main goal of doing this is to help
- 3:47for the education around the convergence between Bitcoin and energy.
- 3:53But also a lot of our customers at Zaporite
- 3:55and early adopters of Bitcoin payments
- 3:57are in the mining ecosystem naturally.
- 4:00They have revenue that's Bitcoin-denominated
- 4:03and they have customers willing to pay in Bitcoin.
- 4:06But most importantly,
- 4:09there are these knowledge gaps that exist around
- 4:12Bitcoiners not appreciating energy,
- 4:15Bitcoin miners really being sophisticated in energy and energy economics, but maybe not being as familiar with the technical underpinnings of Bitcoin.
- 4:28And then there are legacy energy professionals and legacy energy industry that have a lot to add to Bitcoin but don't understand it, as well as regulators and legislators that specifically influence policy or grid operations that would benefit for a Bitcoin podcast that was focused around not just mining but energy fundamentals and how that converges.
- 4:56And, um, given the fact that the TFTC studio is here and that we're in the center of hash being, uh, Texas and everything that's happening around the state, it won't just be about ERCOT and what's going on in Texas.
- 5:07But I thought, uh, we could leverage the infrastructure that's already here.
- 5:10We got the best studio in America, maybe the country, probably the world.
- 5:15Yeah, definitely Austin.
- 5:16Um, so yeah.
- 5:18So, and you have a long history of working on mining, you know, from various different cross sections of it.
- 5:23And so, yeah, looking forward to diving into helping Bitcoiners understand the energy side, helping miners further entrench themselves in the working of the network and their role to play in it.
- 5:38Because I think one of my observations is while there are different aspects of Bitcoin mining that are centralized and potentially increasingly centralized, it's really to the detriment, ironically, to miners themselves.
- 5:52and that the miners have a role to play
- 5:57in helping to solve that problem.
- 6:00Yeah, I agree.
- 6:01The energy rabbit hole,
- 6:03I've fallen down it twice.
- 6:06Once early in my career,
- 6:07I was working at a managed futures fund.
- 6:09We were trading commodities,
- 6:11energy being part of a bucket of commodities.
- 6:15So I learned a lot about macro influences on energy,
- 6:18but I didn't really fall far down the rabbit hole
- 6:21until Great American Mining.
- 6:23I joined them in 2018.
- 6:25And we went on that journey to mitigate flare gas
- 6:29in the Bakken using Bitcoin mining.
- 6:31And it is hilarious to me that you can spend years on Bitcoin.
- 6:38Myself, I understand the economic principles,
- 6:41the distributed protocol, how it works,
- 6:43and even really understand hash rate
- 6:46and the difficulty adjustment.
- 6:47But it wasn't until I joined Great American Mining
- 6:51and really was forced to do a deep dive on Bitcoin mining economics,
- 6:57which forces you to understand energy systems
- 7:00that I came to have like a full grasp of the industry.
- 7:04And even today, I won't admit to be the end-all be-all expert
- 7:09on Bitcoin mining and the intersection of mining and energy,
- 7:12but I think I know enough to be dangerous
- 7:14and have learned a lot over the last seven years
- 7:18to have a pretty good perspective
- 7:20on where the market was in the past,
- 7:23where it is today,
- 7:24where it may be going in the future.
- 7:26Yeah, maybe talk a little bit about,
- 7:28so you joined Great American Mining in 2018.
- 7:32You've worn the hat of an operator.
- 7:36You mine yourself, I believe.
- 7:40You 1031 invests in mining companies.
- 7:44You sit on a board of a mining company.
- 7:46but from 2018 to today 2025 in your view how has not just like the industry changed
- 7:57but the sophistication around energy strategies may be advanced i think it's in order of magnitude
- 8:05it's made in order of magnitude probably multiple orders of magnitude advancement in terms of
- 8:11the understanding because you have all these i think the 2021 chinese mining ban like really
- 8:17forced operators in the united states to step up their game and really think about the power
- 8:22aspect um very very hard and i think we've seen that the products of that here in ercott and
- 8:30to a lesser extent but pretty advanced as well up in the tennessee valley authority in the tva
- 8:37and
- 8:38there's
- 8:39that's the thing
- 8:40with mining
- 8:40and energy
- 8:41there's so many
- 8:42variable inputs
- 8:45that go into
- 8:46both industries
- 8:46it's like trying
- 8:47to combine them
- 8:48is
- 8:49you have to be
- 8:50very smart
- 8:51but it's also
- 8:52like an art form
- 8:53you have timing
- 8:54the market
- 8:54on the energy
- 8:55side of things
- 8:56and timing the market
- 8:57on the Bitcoin
- 8:58side of things
- 8:59I think
- 9:00when it comes to
- 9:01mining
- 9:01when you go back
- 9:03to
- 9:03when I first
- 9:04got in
- 9:05you had
- 9:06like
- 9:07yes 17s coming out yeah the what's minor m20s is and so uh on just a hardware side we've had
- 9:16incredible advancements in the efficiency of the machines in terms of joules per tera hash like how
- 9:22much they can produce much more hash with smaller amounts of energy um and at the same time you've
- 9:30seen the proliferation of these publicly traded miners like riot marathon clean spark iron and
- 9:36they really industrialized mining particularly on grid but then you have this whole other aspect
- 9:43which is off-grid mining and now with projects like the bid axe you're getting at-home mining and
- 9:49there's many different ways to skin the cat of a mining operation and i think between even before
- 9:572018 i think between 2016 and within the last two or three years the advancements on the hardware
- 10:04side were um were so quick and the way in which you acquired asics was not how it's done today
- 10:13which i think is much more efficient and better for the miner but you had like pre-sales and pre-orders
- 10:18and the cost per tera hash got out of whack in 2021 particularly but i think we've settled down
- 10:25into a point in time where the operators are more professional they're more methodical about their
- 10:33deployment of capital both on the hardware side and the infrastructure side of locking down the
- 10:39power and building it out and so as it stands today i think the inner the mining industry has
- 10:46matured i do think outside of ercott and even within ercott to a certain extent energy producers
- 10:52really have not fully grokked bitcoin mining and how it can increase their efficiencies and their
- 11:01revenues and make their operations more secure in the long run, economically viable, sustainable,
- 11:09as you like to say.
- 11:10There definitely are some who get it and are early leaders, but I think the mining industry
- 11:16has matured to a point.
- 11:17I do think the energy industry is lagging a bit in terms of understanding the benefits
- 11:23mining can provide them in the long run.
- 11:26Yeah.
- 11:26And for a frame of reference, and I want to go back a bit, but I believe in 2017, the network had approximately five exahashes.
- 11:38And today it's 800, between 800 and 900.
- 11:43Yeah, between 800 and 900.
- 11:45So the network hash rate, and I want, you know, for, given that this is the first podcast of this series that we're doing under the TFTC umbrella, I want to do some basics to just ground people, even Bitcoiners, and what certain things represent and are.
- 12:05But that's just as an order of magnitude, hash rate in the Bitcoin network has increased by 160 times the past eight years.
- 12:13And that necessarily as mining becomes more competitive, and there might be various reasons that turning on a home miner and solo mining with a small amount of hash rate doesn't need to be thought of the same way that a miner that is running a sophisticated operation might think about their own economics.
- 12:38But over the past eight years, it's shifted to if you are going to have a viable Bitcoin mining operation and, you know, whether it's people that own power generation start to look at Bitcoin mining, that increasingly it seems like just out of the increase in the hash rate of the network, that if you're not optimizing for an energy strategy or realizing that you're in the business of energy development and procuring cheap power and optimizing,
- 13:08around that that you're not going to have a sustaining operation do you where do you see us
- 13:16in that kind of process to the shift of big efficiency gains coming from the hardware side
- 13:22versus optimization around energy and cost of energy or uptime downtime curtailment thinking
- 13:29about that i think we're definitely in a better spot but have a lot of room to grow there and i
- 13:36was actually in dc last week at the bitcoin policy institute summit and i was talking with
- 13:41rey browning and isaac fithian who were at great american mining with me and they're still in the
- 13:46industry and we were having this conversation our thesis even at great american mining
- 13:49was that ultimately due to the competitiveness of the mining market as you mentioned bitcoin
- 13:57mining is the most competitive ruthlessly competitive market in the world anybody can
- 14:02buy an ASIC or excuse me, an ASIC's not the right term, can buy a mining machine with a bunch of
- 14:07ASICs on it, plug it in and boom, they're competing for, they're producing hashes and competing for
- 14:12the production of blocks and the reward that is Bitcoin, the subsidy, plus the transactions
- 14:18associated with the fees associated with the transactions in that block that they may ultimately
- 14:24win um and our thesis back at great american mining was that ultimately power companies are
- 14:33like it's either who's going to become who first the miners going to become energy companies or
- 14:38the energy company is going to become miners they're going to converge and just be one
- 14:41operation at some point and so at great american mining we were doing off-grid mining we learned
- 14:46this lesson the hard way we were doing flare mitigation in the bakken on the well pad and
- 14:54harsh conditions in the middle of North Dakota. And we learned the hard lessons of sort of gas
- 15:01quality flow quality depending on like if the pipe froze because it was negative 40 degrees that could prevent you from actually being able to run a generator uh pipeline access and right of way like we learned the hard lesson at one point in 2019 that we
- 15:21got an operation set up on the well pad we were taking gas would otherwise been flared but then
- 15:27midstream capacity opened up and so they were able to actually flow the gas into the pipeline
- 15:33to take it to midstream.
- 15:34So we had the gas taken away from us.
- 15:37And then on top of that,
- 15:38you have mineral rights owners.
- 15:39They're getting smarter about the fact
- 15:41that some of these operators
- 15:42are bringing in mining operations
- 15:44to mitigate flare,
- 15:46and that's producing revenue
- 15:47in the form of Bitcoin that's being mined.
- 15:50And they're getting involved
- 15:51in the conversations like,
- 15:52hey, you're using my minerals.
- 15:54I'm supposed to have a 12.5% royalty
- 15:56on any revenue produced by this.
- 15:58Typically, it's at the midstream,
- 15:59but there are some intricacies.
- 16:02since it was happening on the well pad, technically, they didn't have to give them the royalties.
- 16:07And so now you have like mineral rights owners beginning to write like mining royalties on
- 16:13the well pad into their contracts.
- 16:16And on top of that, it's like logistically, this off-grid mining model is logistically
- 16:20a nightmare because you drill a well, you get the oil, you have a steep decline curve
- 16:25And that gas, that archetype of gas, flared gas, is not sustainable or reliable in the long run.
- 16:34And so we always had the idea at Great American Mining that eventually, and so this is like-
- 16:40It's not sustainable or reliable because the gas-
- 16:42The gas is not consistent.
- 16:44The amount of capacity is declining.
- 16:45Yeah.
- 16:46The amount of power that you can generate at that site is variable because of that, but variable in a declining sense.
- 16:51that you basically have a mining operation at a site that can't be operated reliably at full
- 16:58utilization exactly and so the analog here and like our thesis was like ultimately what actually
- 17:05makes sense and so the analog would be like a midstream provider is like a power generator
- 17:10or utility on grid and i think this is beginning to happen where we always said like what ideally
- 17:16makes sense as you go to the midstream operators who are who are basically aggregating all the gas
- 17:23from upstream and processing it and then sending it to utilities to run power facilities it actually
- 17:30makes sense for mining operations to exist at the midstream and act as this sort of pressure
- 17:36release valve for pipeline capacity next to a processing plant yes and so i think i've talked
- 17:43Maybe describe a little bit about that, that there's pipelines from the well site going to the processing plant and then from the processing plant to the generators.
- 17:51Yes.
- 17:52And so you have this upstream, midstream, and downstream, like the generators, is the way I would describe it and understand it.
- 17:59And what actually makes sense is if you want to prevent flare upstream, what you really need is more pipeline capacity.
- 18:06because that's typically not it's not every instance there's some instance where you have
- 18:12to flare because they don't have access to a pipeline to send it in the first place but
- 18:15there's a lot of situations where they're flaring because pipeline capacity doesn't exist it's full
- 18:21and so you just have this excess gas you have to burn off so what actually makes sense
- 18:25is instead of logistically trying to plop down mining operations at these different
- 18:31upstream well pads what you do is you just put a big sort of base load at the midstream
- 18:37and you basically have this offset right at the co-location or the aggregation site of the gas
- 18:46coming from upstream and when you need more pipeline capacity if they're drilling more wells
- 18:51upstream on on the well pad you just simply divert some of the gas to the mining operation you let
- 18:58the generators that are running the miners consume the gas open up capacity and prevent flaring
- 19:03upstream and so we would call that like sucking and flare from the midstream is how we would
- 19:09describe it and so i think on the off-grid set that's where i would like to see things go and i
- 19:15have talked to some miners who've included in on that and some midstream providers who have
- 19:20recognized this and are beginning to implement that strategy but that's similar to on-grid
- 19:25demand response and where i think ultimately it goes is the power generators regulate it's a it's
- 19:30a regulator of excess yes and and so i want to i want to come back to this because i want to
- 19:36want to get the thoughts of like why sitting at the midstream versus more optimally at the point
- 19:43of generation for someone that is converting gas to power to then supply to the grid of of whether
- 19:54it's a balance between both of those points kind of essentially providing regulation at different
- 19:59points in the the power generation supply chain but before that i do want to just rewind on
- 20:08anchoring somebody that is less familiar the space do two things how
- 20:16you describe the function of bitcoin mining in terms of its what it is doing for the bitcoin
- 20:23network as well as the nature of power demand for the bitcoin network and how it differs from
- 20:35all other sources of power demand yeah it's actually then i want to come back after i kind
- 20:41of anchoring in those concepts i want to come back to the discussion on you know where power
- 20:45generation for bitcoin mining might be most optimally set no this is very fitting as i was
- 20:49tweeting about it earlier proof of work over everything and i was quote tweeting elon musk who
- 20:53was he's tweeted out something about physics like you can't fake physics uh like nothing you can't
- 21:01you can't 51 attack physics if you will physics is the truth and so i guess that is
- 21:06the sort of reason that we use proof of work in bitcoin mining like bitcoin is this distributed
- 21:14monetary system and the whole reason for bitcoin existing is because we want to separate
- 21:20state and money and we don't want central authority over the monetary system we want
- 21:27a monetary system that anybody can audit anybody can verify and everybody knows
- 21:32what's going to happen when in terms of how blocks are going to be produced and how much bitcoin's
- 21:38going to exist on the market at any given point in time and that's the function that mining plays
- 21:44is sort of regulating the distribution of Bitcoin.
- 21:49And then on top of that, the facilitation of transactions on the network on a block-to-block basis.
- 21:56And so mining is sort of this melding of the physical and digital world using physics
- 22:02in the sense that it's taking an energy source, turning it into electricity,
- 22:09pushing it through these computers that produce these hashes.
- 22:14And then those hashes basically create a market for block production.
- 22:20If you find a particular hash that is below the difficulty target,
- 22:24you present it to the network.
- 22:27The rest of the miners and the nodes say,
- 22:28yep, that's the hash that's below the target.
- 22:30You can add a block of transactions.
- 22:32They do that.
- 22:33You're rewarded in Bitcoin.
- 22:34So there's a lot there, but describe what...
- 22:37You just said block production,
- 22:39and if a bunch of people have no idea what that means,
- 22:42like...
- 22:44It is enforcing the fixed supply of Bitcoin as well as validating all changes in state,
- 22:50which are represented as people sending Bitcoin from one address to another,
- 22:55one address to another, people all over the world,
- 22:58and ensuring that only valid transactions be processed.
- 23:03Yes.
- 23:04And so that's the process.
- 23:08Why is mining important?
- 23:09because to ensure that the system is distributed, decentralized,
- 23:17you basically need this process where anybody can contribute to block production
- 23:21by plugging in one of these computers that produce hashes.
- 23:26And that's the way we create a fair system.
- 23:28There's no central sort of authority who determines like,
- 23:32okay, these people are trying to make these transactions at this given point in time.
- 23:36Let's just aggregate them in a block and put it on the blockchain.
- 23:41You don't want a central authority to do it.
- 23:42You need distributed, economically incentivized actors to do that.
- 23:47And you can't fake a jewel.
- 23:48No, and you can't fake a jewel and you can't fake a hash.
- 23:52And that's what you've mentioned, the 180x increase in hash rate.
- 23:56Over the last seven years, that is a product of more people
- 24:00sort of entering this race of block production
- 24:03to hopefully produce Bitcoin at a cost that is cheaper than the market rate for which they
- 24:10could sell it right now.
- 24:11And so that's describing the function of mining within Bitcoin.
- 24:17But now I want you to describe a little bit in your own perspective of the nature of Bitcoin's
- 24:25demand for power and how it differs from all other sources of power in the market.
- 24:33And if you could, because one of the ways that, as we're thinking about names for the podcast, which we're still working on settling on, is thinking about what is actually happening.
- 24:45And you described it where basically there's energy in some stored state.
- 24:51It's transformed into electricity.
- 24:56That electricity is effectively converted to computation.
- 25:00computation which releases heat and through that process of
- 25:08essentially creating computer or hashes derives from computing power bitcoin network is
- 25:17enforcing its fixed supply validating currency transactions all over the world without a
- 25:23centralized third party and it's separating actively ownership of the network from validation
- 25:30yes in a way that anybody can participate in but then if it's demanding some form of
- 25:40stored energy converting that into power now describe what makes the nature of bitcoin's
- 25:48power demand you in the market because it is a fundamentally new source of power demand that
- 25:54prior to bitcoin did not exist realistically when bitcoin was very small it demanded very little
- 26:02power and that as it as it grows the more power it consumes the more relevant it becomes to energy
- 26:10systems and the more it can potentially solve energy problems yeah and so i guess the nature
- 26:17of the demand for power from bitcoin miners at any given point in time is contingent
- 26:24on a couple of things number one how expensive or cheap is that power number two how expensive or
- 26:32how much is bitcoin worth at that given point in time and running the calculations of your energy
- 26:39costs let's add infrastructure and operations and all that into that and the price of bitcoin
- 26:44at any given point in time you're you're basically going to consume power if you think you can produce
- 26:50a bitcoin um for less than you could sell it at the market at any given point in time so i think
- 26:55that dictates the demand for power from the bitcoin network at any given point in time
- 27:02um with that being said i think the interesting thing that bitcoin mining brings to the world
- 27:09is demand for power sources that previously had no demand.
- 27:13And so in the example, Great American Mining,
- 27:16flare gas was something they were literally setting on fire
- 27:20because nobody wanted that gas
- 27:23because there was no ability to monetize it
- 27:27because it couldn't get to market, right?
- 27:31It was stranded energy,
- 27:32like out in the middle of these oil fields.
- 27:34And that's the beauty of the Bitcoin mining network
- 27:38is that it brings a new form of demand to energy resources
- 27:43that for a very long time were simply just wasted
- 27:46because there's no way to monetize them.
- 27:49So I think Ross Stevens has written very eloquently about this
- 27:54and many others, like Bitcoin mining is this pioneer species that...
- 27:59Brandon Quittem also wrote in.
- 28:00Brandon Quittem.
- 28:00Yeah.
- 28:01That can monetize energy sources that were previously unmonetizable.
- 28:06And so it brings demand for that archetype of energy that's existed for a long time, but has never been able to monetize. And this is possible because the Bitcoin network is distributed. And so if you have the ability to generate electricity, the computers that produce the hashes that ultimately get you Bitcoin, and an internet connection, it could be a cellular internet connection.
- 28:35And that's the thing miners, when they're sending their hashes to the network or a pool, takes kilobytes of data.
- 28:43So you can use pretty low latency.
- 28:46Significant amount of work at the site, but very little data transmission.
- 28:51Yeah, when you're interacting with a network, you're selling kilobytes of data when you're sending your shares to a pool or to the network directly.
- 28:58um and so that creates a beautiful thing where you can go and you can monetize
- 29:04these these previously unmonetizable energy sources on site so you bring the market to
- 29:12the molecule is one of the things we would say at great american mining and the network isn't
- 29:18dependent on any one individual miner having 100 uptime anywhere in the world because it's
- 29:24distributed um and so you can have just explain that because i think that's a really important
- 29:28concept that it's functionally that miners are suppliers to the bitcoin network and that the
- 29:37bitcoin network is is the source of demand it's basically aggregating demand all over the world
- 29:44and then distributed suppliers and just talk about like the the that as a concept um and
- 29:54and significance of it.
- 29:56Yes, it's location agnostic.
- 29:58And since Bitcoin's a distributed system,
- 30:01you can have disruptions to individual parts
- 30:05of the mining industry,
- 30:07of individual mining operations
- 30:09without disrupting the distributed Bitcoin network.
- 30:12The extent of this disruption,
- 30:15if it hits a critical,
- 30:17or not a critical scale,
- 30:18but a certain scale,
- 30:20is just slower block production And I think that Right but making that point if a hospital stops pulling on power the operation of the hospital shuts down
- 30:31Now, if a Bitcoin miner shuts down,
- 30:34its operation shuts down,
- 30:36but the Bitcoin network continues to operate
- 30:38just slightly slower.
- 30:39And the actual operation that is generating
- 30:44that is the source of demand
- 30:47is the Bitcoin network itself.
- 30:49which the miner is supplying.
- 30:52It's a part of the supply chain,
- 30:54but it's not the actual in-demand.
- 30:57No.
- 30:57The in-demand is the people looking to send Bitcoin
- 30:59from one place to another.
- 31:01Yeah.
- 31:02And this is a beautiful thing.
- 31:04Hospitals, one example.
- 31:05Amazon Web Services, cloud data centers,
- 31:09the AI compute, particularly for model training.
- 31:14They cannot have disruptions.
- 31:16They need consistent power.
- 31:18or in the case of Amazon,
- 31:20if one of their data centers goes down,
- 31:23like you have websites that'll go down,
- 31:25like critical business infrastructure
- 31:26that will literally go down.
- 31:28Maybe they have some redundancies,
- 31:30but I think it's safe to say
- 31:31that they need significant amount of uptime
- 31:34and reliability.
- 31:36Whereas the Bitcoin network,
- 31:37an individual mining operation
- 31:39may want that uptime,
- 31:41but it's not critical to the Bitcoin network
- 31:43being able to facilitate transactions.
- 31:45There's another piece of that,
- 31:47which is that it's a,
- 31:50and you mentioned this before,
- 31:52but it's a,
- 31:52it's a functioning,
- 31:53a purely economic source of demand.
- 31:57And in some form or fashion,
- 32:00but in a more derivative way,
- 32:02every demand of,
- 32:05for power is refining that power into some higher ordered good to ultimately
- 32:09have an economic incentive.
- 32:11But Bitcoin mining is essentially the least refined that has a,
- 32:17direct monetization to money not needing to refine it into something else to then
- 32:23deliver a good or service to trade it and for that reason it's this aggregated source of demand
- 32:30being the bitcoin network as well as this purely dollars and cents bitcoin and sats
- 32:37do i consume this power because all i'm using it for is to turn it directly into money not some
- 32:43other good or service exactly yeah and it's a beautiful thing too because bitcoin trades 24 7
- 32:49365 it's extremely without counter party risk extremely liquid pools you have some counter
- 32:55party risk yes and i'm sure we'll get to it but like the pools have created payout structures
- 33:01which are a problem right now but um we're gonna make it so you can get paid out every day uh
- 33:06and so yeah you do have this stream of ink or revenue that you can convert to dollars when
- 33:13when you need to immediately and a lot of miners i think have really gotten smart about managing
- 33:20their their bitcoin revenue and inventory um in ways that are advantageous for the long-term
- 33:26viability of their businesses but yeah long story short bitcoin mining is this demand source that is
- 33:34location agnostic um and has the ability to be flexible in the sense that uh if a mining
- 33:42operation goes down it doesn't really critically impair the bitcoin network and if it's more
- 33:48profitable for them to turn down because it might be more costly to continue to run and they have a
- 33:54direct incentive to do that yeah and we've seen that in the last we just had the largest difficulty
- 33:59downward difficulty adjustment in i believe five years earlier this week and this is a product
- 34:05product of the heat wave that's been going going across that yeah so maybe this is a good
- 34:12Iranian nuclear sites, but I don't want to go down that.
- 34:16No, I think this is important though.
- 34:18And going back to the first time I dove down the Bitcoin rabbit hole,
- 34:24and I think this is actually this sort of theme that we're pulling on here
- 34:28is indicative of Bitcoin mining becoming a truly industrialized commodity producing business.
- 34:34When I was working at the Managed Futures Fund,
- 34:36who are following net gas markets, WTI, power markets, just generally, I found it fascinating
- 34:45because you could have geopolitical events or weather events in certain parts of the world
- 34:50really materially affect those markets. And we're beginning to see that in Bitcoin, particularly as
- 34:57more miners become engaged in demand response within grid systems. And so last week, like earlier
- 35:05this week we had the largest downward difficulty adjustment we've had in many years it was negative
- 35:107.7 percent um and as you alluded to there were many people that were pointing at the united
- 35:21states bombing iran's nuclear enrichment sites and saying oh my gosh iran was running these mining
- 35:29operations there that's why hash rate fell and i think it's been very well known that iran
- 35:35certainly does have a material amount of hash rate within its borders but i think people were
- 35:42i think it's clear because you can look at the ercott data specifically but
- 35:46literally right around the same time that we were bombing iran the heat wave was starting to hit the
- 35:50united states and the northeast and here in texas and it was just a coincidence that we were bombing
- 35:56iran while that was going on and what was actually happening number one we we bombed nuclear
- 36:02enrichment sites which aren't power facilities and so like it doesn't make any sense that
- 36:06if you're going to have something as high stakes as a nuclear enrichment site that you would
- 36:11co-locate a bitcoin mine it doesn't make any sense they're not like actually producing power
- 36:15there you if you are producing power there you probably want to spend it all on the enrichment
- 36:19and i'm not going to make any assumptions there um oh we had the heat wave going on here and some
- 36:25miners that were engaged in demand response the pricing signals that they were getting were oh
- 36:30oh, it's too expensive to mine Bitcoin.
- 36:33And we're in this program that will pay us
- 36:35if we shut down and send our electricity back to the grid.
- 36:39And that's actually what has been happening
- 36:41over the last week.
- 36:41It's been a hundred,
- 36:43it's crazy actually coming back down here.
- 36:44It's been hotter.
- 36:46The heat in Jersey has been more oppressive
- 36:47than it is here.
- 36:48It's actually relieving to be here this week.
- 36:50Yeah.
- 36:53Last couple of summers, totally brutal.
- 36:55This summer, more mild,
- 36:56you know, people get adjusted to,
- 36:58but it is interesting that,
- 36:59because one of the things that I mentioned
- 37:03and when we're starting to see it,
- 37:07but I expect it to grow
- 37:08is that when Bitcoin was very small,
- 37:13its demand for power was small
- 37:16and the larger that it's grown,
- 37:20it can actually impact.
- 37:22It needed a certain level of scale
- 37:25to be able to actually be relevant
- 37:28to an energy system
- 37:30and thinking about something like ERCOT
- 37:32and I want to use this to segue back
- 37:34to that question of
- 37:36where optimally and my
- 37:38expectation is, I want your thoughts
- 37:41is that Bitcoin mine will exist everywhere but
- 37:42geographically as well as
- 37:44at different places where there's
- 37:46underutilized energy assets
- 37:49but
- 37:49if Bitcoin can effectively solve
- 37:52an upstream problem
- 37:53in certain scenarios
- 37:56a midstream problem
- 37:57and then in the case of conversion power generation for the grid downstream problem
- 38:06now my understanding is that bitcoin mining in ERCOT is like three to four
- 38:12gigawatts a functional base base load and that peak in the summer which i'm sure we're not
- 38:20all-time highs but either last summer the summer before we had hit something around 90 gigawatts
- 38:26of power that four gigawatts taking that off line at peak demand is enough to provide not just a
- 38:36service but relief to the grid itself um so how do you think like in terms of actually being value
- 38:45additive that if you think about you know peak demand in texas in the summer being between 80
- 38:52to 90 gigawatts if you were only drawing 100 megawatts power in terms of bitcoin miners in
- 38:58texas it can't really solve material problems but it's four gigawatts it starts to solve a problem
- 39:04if it becomes 10 it can solve problems more effectively how do you think about how bitcoin
- 39:11mining can solve problems coming back to what you were saying of maybe the most optimal location
- 39:16might be at a midstream processing plant,
- 39:21but thinking about it relative to maybe that,
- 39:27why do you think that might be most optimal,
- 39:29but how do you think Bitcoin mining can be distributed
- 39:32to in parallel or in tandem solve different types of energy problems?
- 39:39To be clear, I think the midstream application is optimal
- 39:43for upstream energy producers
- 39:47that have problems with gas
- 39:49that they can't get into a pipeline.
- 39:51I think it's optimal for solving that problem.
- 39:53Does that essentially increase
- 39:55the economics of a pipeline
- 39:57to allow for more pipelines to actually get...
- 39:59Yes, you can drill more oil
- 39:59and you can get more gas to market
- 40:02and then monetize that gas
- 40:04that would otherwise be wasted,
- 40:06at least in the Bakken
- 40:07where they have strict flaring regulations.
- 40:09And so if you flare a certain amount,
- 40:11you have to shut down the well pad
- 40:13which means they really care about the oil at the end of the day i mean gas is a byproduct but if
- 40:18you can create a better a more an actual economically sustainable path offload gas
- 40:25then you can actually produce more oil and on top of that you can monetize the gas which
- 40:29wasn't possible before so you're getting like compounded efficiencies there but that's optimal
- 40:33for that specific problem on grid there's many other like i'm thinking of two things right now
- 40:40I'm sure you've seen the charts of Chinese energy production over the last
- 40:44three decades versus energy production growth versus U S energy production.
- 40:48Stagnation flat and ones,
- 40:51you know,
- 40:51not necessarily hockey sticking,
- 40:53but very linearly aggressively rampant.
- 40:56Yeah.
- 40:56Like it needs,
- 40:57we need to catch up with China in terms of generation expansion and capacity
- 41:03expansion just throughout the United States.
- 41:06Texas has done a very good job.
- 41:08Like I was going to say,
- 41:09who's we here yeah well still texas like demand's only going to continue to rise in texas and i
- 41:15think at a pretty steady clip as it becomes this bastion for free markets and enterprises that want
- 41:22to escape hell holes like california in the northeast and actually build down here you have
- 41:27foundries coming online in taylor i believe you have samsung building a foundry there i think
- 41:33there's another one being built north of houston and you're going to need a ton of energy for that
- 41:38And you have Tesla, SpaceX, all these companies coming to Texas to build physical things.
- 41:44They're going to need a lot of energy.
- 41:45And on top of that, you have the residential, sort of the exodus from some of these states that are oppressive from a tax perspective or civil liberties perspective and freedom-minded individuals flooding to Texas to sort of reap the benefits of the government and law that exist here.
- 42:06And so I think demand is going to increase, but back to Bitcoin mining, like we need to increase generation and capacity. And I think Bitcoin, like a lot of the problem with doing that is like, how can you make the economic case? Like it takes a ton of money, a ton of time. And how can you reduce risk while you're expanding generation at a fast clip?
- 42:29Bitcoin mining's a perfect solution, a perfect way to de-risk energy generation because you have an immediate buyer of the energy.
- 42:40And so I think one of the prime examples of Bitcoin being this pioneer species for energy production is the fact that you can build a power facility and then put a mining operation behind the meter.
- 42:52So before it hits transmission lines and consume energy there, and that's one of the problems that arises when you want to expand generation is you can build a power plant, then you got to build transmission to actually connect it to the grid so that the electricity can flow to consumers at the end of the day.
- 43:09there there's a time dilation there um that that exists where you have your facility that could
- 43:16produce energy but isn't doing it because there's no transmission to get it to market so bitcoin
- 43:21miners can sit behind the meter on site at the the place of generation and be that revenue producer
- 43:28for the the generation asset um before transmissions build out that's one and uh
- 43:35I actually have a cousin who runs a nuclear facility in Nebraska.
- 43:41I've mentioned this to you, but we were talking about it two years ago.
- 43:44I need to call him again, but he was describing to me a problem that he has.
- 43:50They've overbuilt wind capacity in the region out there to the point where it drives his prices negative.
- 43:58It's very costly to shut down.
- 44:00Shut down, so you have to keep the nuclear facility running.
- 44:03Prices are negative.
- 44:03You just have to eat that cost, essentially, and this is due to an overproduction of wind specifically.
- 44:11But Bitcoin mining helps in that case, too, where if you have a Bitcoin mining operation behind the meter and wind starts overproducing and your nuclear power becomes economically non-competitive because the wind is cheaper for people to consume.
- 44:28or there's just too much of a supply of power in that particular grid system.
- 44:33And you have to eat the cost of running negative prices.
- 44:37Bitcoin mining operation behind the meter, instead of eating those negative costs,
- 44:41you just energize the mining operation and make revenue from the mining.
- 44:45And so in terms of the importance of Bitcoin mining within the energy sector for producers,
- 44:52specifically, I think in terms of expansion of generation and capacity,
- 44:56you have a buyer first resort that de-risked the operation from a speed to revenue perspective and
- 45:03then for generators that are already up and running and are running into these problems
- 45:11and negative pricing due to the variability of wind and solar production in in their grid systems
- 45:19that you have this sort of economic load
- 45:21that you can divert your energy to monetize on the go.
- 45:27You mentioned, and I always,
- 45:28I don't have a clear mind of what it,
- 45:32the right framing of it is whether Bitcoin the buyer of first and last And last It effectively Bitcoin miners should in theory be willing to pay the least
- 45:46for power,
- 45:46but they're most capable of absorbing excess power or energy assets that are
- 45:55underutilized that could be generating more power.
- 45:57Yeah.
- 45:57So what I just described in the generation expansion,
- 46:02put it behind the meter before transmissions build out that's first resort the nuclear power facility
- 46:10that has the stomach negative pricing that's last resort it's like nobody's going to buy this price
- 46:15they're going negative because there's an oversupply i need a buyer of last resort to come in and soak
- 46:20this up and so that's that's when you have a mining operation behind the meter there on the
- 46:24back and when transmissions sufficiently build out and the ability to supply that particular market is
- 46:30robust uh to the point where prices are going negative it's like all right last resort i'm just
- 46:35gonna mine bitcoin with this because otherwise i'm just eating costs yeah and of course there's
- 46:40cost of the mine itself to as to whether or not it's economic and that might you know be
- 46:44or not might be that translates to whether a site or a solution is actually viable as well as what
- 46:52a bitcoin miner would be willing to pay or not pay for power well this is ultimately why i think
- 46:57generators become miners um because when it comes to like controlling the cost at the end of the day
- 47:03it's a race to the bottom and if you're playing this out over 5 10 15 years power generators are
- 47:11gonna have the most control over those costs and right and i think that maybe another way to say
- 47:18that i mean i i i tend to agree but i'm also on this this journey of trying to understand better
- 47:23myself and that's part of what this podcast is about is any any point further from where
- 47:32some energy resources are converted power electricity the further you get from that point
- 47:40the more cost that exists and it doesn't necessarily mean that bitcoin mining won't
- 47:49exist in places other than the point of generation,
- 47:54but that you're optimizing for cheap power and that there would have to be some
- 47:59other economic reason where an asset could be monetized
- 48:05increasingly to justify it not being at the point of generation.
- 48:12And that might be because there's a large substation that already exists and it
- 48:16can be an energy arbitrage and turn off and you know that there's a there's a valuable you know
- 48:23there's a value there's a reason for an energy system for a bitcoin mine to exist someplace
- 48:27but if they're optimizing for cheap power that transmission lines are cost right and if you can
- 48:35help be a balancing to load closest to the source that there's a very rational reason why why it will
- 48:45shift that way over time yeah it's about identifying and taking advantage of all the
- 48:50different and that's the crazy thing as i've learned over the last seven years diving down
- 48:53the energy rabbit hole there's so many different types of arbitrage opportunities like what we just
- 48:59described with the negative pricing and the expansion of generation before transmissions
- 49:04build out like upstream with the flare gas um there's so many different ways to skin the cat
- 49:10again of of r being the cheap energy so like a cathedral what we're doing in the tva it's a
- 49:17different form we're not going straight to the power generator we're going to the utilities that
- 49:22own substations that have excess capacity it's not being utilized because they were built decades ago
- 49:31serving large manufacturing facilities that due to globalization have since moved out and so you
- 49:37built a 20 50 megawatt substation thinking that you're going to serve the steel factory um and you
- 49:44were in the beginning but ultimately just the economics of steel production were so that you
- 49:50had to export that process somewhere else and that's a great like you brought up the idea of
- 49:55the pioneer species that ross stevens has written about brandon quinton has written about others
- 50:00where it's like it's the first kind of demand and then it makes a place inhabitable and then other
- 50:07species come that's the idea of a pioneer species this is what you just described and consistent
- 50:13with that where there was an energy asset it was abandoned and then a bitcoin miner can come in and
- 50:22absorb that and then over time maybe that industry comes back or there's some higher value yeah and
- 50:33they're willing to for the asset overbid for the energy and they come back an example you know not
- 50:38exactly the same but these bitcoin miners aggregated large sources of of power with high density
- 50:47they were running mining sites and then there's advancements in ai and then these sites are
- 50:53perfect and and the the ai companies are willing to pay more for power and then there's a higher
- 50:58better use than the Bitcoin mine and the Bitcoin miners go somewhere else. But I think this idea
- 51:03where there's all this energy infrastructure where say there might've been in the Midwest,
- 51:07these 50,000 manufacturing plants are gone. Hopefully that manufacturing comes back, but
- 51:14Bitcoin miners can absorb that energy infrastructure, which then allows them to be
- 51:20maintained rather than decayed and have their value to go to zero. And so I think that that's
- 51:27Another very interesting dynamic that fits into this idea of the pioneer species, but in a different way.
- 51:34And one of the things I want to do on the podcast is go focus episodes on each different way that Bitcoin mining solves, can solve a problem in an energy system.
- 51:48but one thing that you mentioned a little bit ago you know not talking about the specific subject
- 51:55but you talked about you know texas increasing in energy demand and about how samsung was building
- 52:02a found foundry to manufacture chips texas i believe there's one out in uh in arizona as well
- 52:11but you know one of the things that we'll explore in more episodes of the podcast is each kind of
- 52:17those those sources of demand um as well as how bitcoin mining can actually solve an energy
- 52:24problem or an inefficiency exists that that creates a problem one of the problems and problem
- 52:32is a loose term and it's always a degree but um shifting the focus is talking about minor
- 52:43centralization. It seems to me, and I want to see if you agree with this, given the nature of
- 52:51where energy resources exist in the world, that the most decentralized and distributed
- 52:59part of the mining ecosystem is actually where hashes are produced. And then the more centralized
- 53:07are where the chips are manufactured as well as where hash rates aggregated the hash rate is
- 53:15aggregated so talk a little bit about if we're shifting you know we'll be diving into all these
- 53:24subjects deeply but trying to kind of set the table for the range of different things that
- 53:29we'll talk about through various different episodes talk about the points of bitcoin mining that
- 53:36that are more centralized than less
- 53:39and how you see that changing or evolving and why.
- 53:46Yeah, so let's start with the ASICs, the chips.
- 53:52So what do ASICs do?
- 53:54ASICs are these computer chips
- 53:56in the same application-specific integrated circuit.
- 54:00So it does one thing and it does one thing well.
- 54:02Bitcoin ASICs, they do hashcash, SHA-256,
- 54:06hashing.
- 54:07I think that's
- 54:08all they do
- 54:08is run that
- 54:10hashing algorithm.
- 54:11You
- 54:12input some randomness
- 54:13it outputs a hash
- 54:14and that's all
- 54:16that these chips do.
- 54:17And not to
- 54:18lose people
- 54:19for the purpose
- 54:20of
- 54:21forcing Bitcoin's
- 54:22fixed supply
- 54:23and validating
- 54:24currency transactions
- 54:25all over the world.
- 54:26And so ASIC chips
- 54:27are like top of the line
- 54:28like to produce
- 54:28an ASIC chip
- 54:29is not easy.
- 54:30It's high risk
- 54:31capital intensive
- 54:33like very specialized
- 54:35and there's
- 54:36only a few chip manufacturers in the world that can do it actually really two right now
- 54:44tsmc and samsung so i mean and really even between the two like really tsmc bitmain is the monolith
- 54:54does samsung produce a basic yeah the what's minor they use oh what's minor does yeah what's
- 55:00uses Samsung's ASICs.
- 55:02And the two largest
- 55:03manufacturers of
- 55:06Bitcoin miners, which include ASICs, are
- 55:08Bitmain and
- 55:10MicroBT, which produces the
- 55:11what's miners, Bitmain produces the end miners.
- 55:14And Bitmain, sorry,
- 55:16Bitmain sources
- 55:17their chips from TSMC. Yes.
- 55:20And MicroBT
- 55:21sources theirs from Samsung.
- 55:24Predominantly from Bitmain,
- 55:26TSMC in Taiwan.
- 55:28As it stands right now,
- 55:29micro bt samsung in south korea that's where the chips are being produced taiwan and south korea
- 55:35and it's hyper centralized has been since asics came to market in 2013 2014
- 55:452013 i believe maybe late 2012 that's when bitmain launched the s9 we've had a bunch of
- 55:54competitors come to market but really bitmain's the goliath and the micro bt's number two and
- 55:58funnily enough micro bt was started by um dr zhong who was previously at bitmain and he designed
- 56:05the s9 which is considered the ak-47 of uh this is an s1 it's one i think we have s9s outside
- 56:16outside yeah there's some rusty s9s out there but they were produced by bitcoin park you can pick
- 56:20up 2013 or maybe later than that the s9 was like maybe 2016. um and some some of those s9s are
- 56:29still running today profitably if you have zero cost energy um the it's hyper centralized but
- 56:37the physical nature of these asics like the chips were reaching the physical limits of how much
- 56:46electricity you can push through them to produce the hashes and so that's this is something that
- 56:50has been talked about in bitcoin money you just you said that but ultimately you want to be able
- 56:55to produce more hashes per unit of energy yes that's the increase in efficiency but you're saying
- 57:00that the ability they're we're reaching the like right now you have three nanometer asics
- 57:08people talking about two nanometer asics then you have one you can't go and reducing the number of
- 57:13of nanometer basically increases the amount
- 57:15of hash
- 57:16efficiency joules per
- 57:19terahash
- 57:19it makes that go down
- 57:22and we're reaching
- 57:25the physical limits I believe
- 57:27who knows if there's some
- 57:28order of magnitude improvement that can be
- 57:31made
- 57:31it's out of my pay grade but
- 57:35I'm pretty sure
- 57:36the point being
- 57:37we're in theory reaching the physical
- 57:41limits of what the best manufacturers in the
- 57:43world are capable of doing which is a very difficult thing to do yes and once you've reached
- 57:48that limit though it's been talked about in bitcoin mining for some time we may hit a point
- 57:53where you get what's referred to as asa commodification where that's the problem with
- 57:59competitors trying to enter the market is that bitmain and micro bt they have access to top of
- 58:04the line chips from a nanometer perspective the smaller the nanometer the more efficient
- 58:09you can be and so the risk of going out there and we saw this with intel in trying to produce
- 58:17i believe they produce like a five nanometer chip and it took them 18 months by the time they got to
- 58:22market bitmain was out with a three nanometer chip and you're just not competitive there like
- 58:28what governs the amount of power that a bitcoin miner can pull is it the number of asics and then
- 58:33each ASIC has a certain amount of
- 58:36like the heat rate that it can
- 58:38support or just explain that
- 58:40I don't know
- 58:41maybe but my pay grade too but like yeah
- 58:43we'll get an expert to come on and talk about
- 58:46you have joules per terahash
- 58:47so you have I mean back at Great American Mining
- 58:49we could put I believe
- 58:52200
- 58:53maybe 200
- 58:57M20S's
- 59:00micro BT
- 59:01what's minor m20s is in a shipping container and that would pull like 700 kilowatts of power from
- 59:08the generator do you have a rough order of magnitude of like say like a single asic how much
- 59:13um power it would be capable so this is a single asic on a board this is i believe an s20 or an s19
- 59:23or an s21 this is five volts this one is it running on five volt power right now but but
- 59:30can you provide some like order of magnitude to help somebody understand like the density
- 59:35relative to a computer and so well to a computer it's it's orders of magnitude higher but i think
- 59:44a better way to frame is like uh in 2017 i believe the joules per tera hash rate was
- 59:51literally over a thousand might have been like 1200 joules per tera hash
- 59:56on average across the Bitcoin network
- 1:00:00that the miners are pulling today,
- 1:00:01it's like 15.
- 1:00:02So we've made top-of-the-line miners
- 1:00:04pulling like 15.5 joules per terash,
- 1:00:06I believe.
- 1:00:08So we've had basically more hashes
- 1:00:09per unit of energy.
- 1:00:11Yes.
- 1:00:12Becoming massively more efficient.
- 1:00:13Yeah.
- 1:00:14Yeah.
- 1:00:14Now,
- 1:00:16describe two things.
- 1:00:20Why it's as centralized as it is
- 1:00:24and what the current risks of that centralization are.
- 1:00:29Because micro-BT has increasingly taken share from Bitmain,
- 1:00:35but Bitmain and micro-BT probably have, in aggregate,
- 1:00:3995% of the market.
- 1:00:41Probably more than that, yeah.
- 1:00:42Okay, but so what is preventing greater decentralization?
- 1:00:49And then...
- 1:00:49what the present risk of that centralization is.
- 1:00:56I think it's access to founder space, right?
- 1:00:58It's expensive.
- 1:01:00Again, it's risk.
- 1:01:01It's capital intensive and it takes time.
- 1:01:05And that is like effectively competing with somebody
- 1:01:09creating chips for GPUs, for AI.
- 1:01:12For AI, for Apple, for whoever.
- 1:01:15You're competing with everybody for space on the foundry floor
- 1:01:18to produce your chips.
- 1:01:19And if you're a large Bitcoin miner and you're planning a site, say a gigawatt site in Texas,
- 1:01:26you might not have reliable access to be able to get chips.
- 1:01:32Well, that's not your job.
- 1:01:33That's Bitmain's job, right?
- 1:01:35Well, no, but what I'm saying is if you're a Bitcoin miner and you're planning the site,
- 1:01:39it's predicated on being able to actually get chips from Bitmain.
- 1:01:42Yeah.
- 1:01:43And that if Bitmain decides not to supply you because they're centralized to supply somebody else,
- 1:01:48That's a source of...
- 1:01:49Yeah.
- 1:01:50But I think a layer down,
- 1:01:52why aren't there more chip manufacturers?
- 1:01:55Because it's not easy to get on the foundry floor.
- 1:01:59And I think MicroBT and Bitmain
- 1:02:01have been in the game for a long time
- 1:02:05and have proven to the foundries
- 1:02:06if they come to me with a chip design,
- 1:02:09they're going to have the money.
- 1:02:10They're going to make a lot.
- 1:02:12For example, Intel tried to make a chip.
- 1:02:17Correct?
- 1:02:17Yeah.
- 1:02:18And they spent years,
- 1:02:22didn't,
- 1:02:22they actually delivered one,
- 1:02:24but then shut down the program.
- 1:02:27Yeah.
- 1:02:27Because there are companies that have a lot of money that have a lot of,
- 1:02:31and this is,
- 1:02:31I mean,
- 1:02:31this is where you,
- 1:02:32this is where you begin to wander into the competition between the U S and
- 1:02:36China,
- 1:02:36specifically from a intellectual capital perspective.
- 1:02:40Like their chip design just wasn't as good as micro BT and it means.
- 1:02:45So they were effectively bringing a chip to the foundry.
- 1:02:48that wasn't they were using their own foundry and intel has their own foundries and just didn't
- 1:02:54compare from uh when they were actually taking it to market the bitcoin miners were saying no we
- 1:02:59need something of either micro bt or yeah yeah they have like r2i and proto which is the block
- 1:03:08company they're going after it and so this is effectively the the capability of the manufacturer
- 1:03:14and their design as well as access to the foundry,
- 1:03:21which is predicated on the capability of the foundry,
- 1:03:25but then also the foundry's availability and perspective
- 1:03:30as to whether you have the capability to actually execute if they get your space.
- 1:03:35Or if you're going to be a long-term customer.
- 1:03:36Are they going to give a foundry space to you
- 1:03:39knowing that you're going to come back year after year
- 1:03:41and there's going to be demand for your product?
- 1:03:43That's the risk the foundry takes.
- 1:03:44Is there something about Bitcoin and its, effectively, simplicity in terms of its operation, like what the ASIC needs to do, that there's less diversity because it's homogenous?
- 1:04:04I again above my pay grade but from what I understand no because any ASIC whether it's
- 1:04:11Bitcoin ASIC or some ASIC for some other application does one thing specific application
- 1:04:16specific so from my understanding ASICs no matter if they're Bitcoin miner or running some other
- 1:04:22type of computer just doing one thing and that's the whole point of producing an ASIC chip is just
- 1:04:27you want to be ultimately efficient at doing that one thing in Bitcoin mining it's just producing the
- 1:04:32hash cash shot to 56 there's no fundamental reason why
- 1:04:35the develop of bit development of bitcoin asics should be any more or less centralized than
- 1:04:43develop of any other asic yeah and again these are subjects that we'll dive into deeper where we get
- 1:04:49the i'm not the asic expert i know enough to be dangerous basic expert into to talk about these
- 1:04:54things at greater detail um but then the second question of of there's the risk to the the
- 1:05:02manufacturer but then to the to the mind to the bitcoin network itself maybe describe risk or if
- 1:05:10if there's less risk because of the function of basic manufacturers just what's your view of
- 1:05:17what risk does this piece of centralization
- 1:05:22in the Bitcoin mining ecosystem represent to the network?
- 1:05:26I think we have to go back in time to 2016, 2017,
- 1:05:31when Greg Maxwell discovered that Bitmain had a backdoor
- 1:05:36in their ASICs called Ampleed,
- 1:05:40where they could remotely brick machines if they wanted to.
- 1:05:43and so i want to talk about risk of uh i mean that's a serious risk both to the bitcoin network
- 1:05:53but also to somebody like ercott you know if they had four gigawatts of power drawing on
- 1:06:01um on the on the ercott grid and a chinese manufacturer could say brick brick yeah that
- 1:06:13four gigawatts comes down all at once yeah but then to the to the bitcoin ecosystem if
- 1:06:1980 of the installed base of machines that are hashing could also be shut down now there's a
- 1:06:28there's a limit to what the um the actual difficulty adjustment can be in any one epic
- 1:06:36Negative 75%.
- 1:06:37Okay, so it's in line with, say, if somebody had 80% market share,
- 1:06:44but how was that resolved?
- 1:06:46Called out, and it was never...
- 1:06:48Was that software firmware?
- 1:06:52Firmware, I believe.
- 1:06:55The firmware was remotely pinging back to central servers,
- 1:06:59and if the central server wanted to,
- 1:07:01they could remotely shut down the machine, is how I recall it.
- 1:07:04This was many years ago at this point.
- 1:07:07I didn't even know about that because that was like right for...
- 1:07:08And this is right around ASIC.
- 1:07:09It was like another thing.
- 1:07:10ASIC was right as I was like getting interested in Bitcoin.
- 1:07:14And then ASIC boost was like another thing.
- 1:07:16It wasn't necessarily a backdoor, but it became apparent that...
- 1:07:19It seemed like just like a marginal economic advantage,
- 1:07:22which may skew things over time,
- 1:07:24but less critical to the actual operation of Bitcoin.
- 1:07:28Yeah, it just gave some...
- 1:07:29It gave Bitmain, essentially, who...
- 1:07:32And also maybe to connect this idea for people that are less familiar with Bitcoin mining is that if 80% of the network came offline at one time and the network state was assuming there to be five times the amount of Bitcoin hash rate, that Bitcoin network would take five times longer to validate transactions and would create a lot of congestion.
- 1:07:59Yeah.
- 1:08:00Okay.
- 1:08:00yeah so that's
- 1:08:03one of the risks but then
- 1:08:04I try not to dwell on this risk
- 1:08:07too much because again going back to the fact
- 1:08:09what about dictating rules though
- 1:08:10dictating rules of the network
- 1:08:12consensus rules yeah is there
- 1:08:14I mean you need to get miners
- 1:08:18on board I think to a certain extent
- 1:08:20but does the concentration of manufacturing
- 1:08:22of ASICs
- 1:08:23no I don't think so
- 1:08:25okay so then
- 1:08:28let's shift because we want to be efficient
- 1:08:30the other source of primary centralization in bitcoin mining is the pool side describe quickly
- 1:08:37like somebody was five what a what a bitcoin mining pool is and again anchoring everyone in this
- 1:08:43this idea that because it's easy to get lost in these rabbit holes which is
- 1:08:49bitcoin miners producing hashes those hashes as a network forcing bitcoin's fixed supply
- 1:08:55and validate in currency transactions,
- 1:08:58where do pools fit in
- 1:09:00and describe the state of centralization
- 1:09:03and, in your view, the risks that are created there.
- 1:09:06Yeah, and so I'm sure many of the people listening to this
- 1:09:10are aware of Bitcoin folklore
- 1:09:13of people plugging in their MacBooks
- 1:09:16in 2009, 2010, 2011,
- 1:09:20downloading the Bitcoin software,
- 1:09:22hitting mine and mining blocks themselves.
- 1:09:25You hear the stories of OGs who simply downloaded Bitcoin on their computers, mined, and accumulated large amounts of Bitcoin.
- 1:09:35And that was the case back then.
- 1:09:37It's not the case now.
- 1:09:38As we described, hashrate has gone up 180x over the last seven years.
- 1:09:42And so what has been introduced in terms of a risk for individual miners is what we call variance risk.
- 1:09:50so as more mining nodes join the network that's more competition to produce blocks to get the
- 1:09:57reward that ensures that any individual miner their chances of mining a block goes down
- 1:10:06significantly and so that means that your payout variance increases so the frequency at which you
- 1:10:14find a block and get rewarded for that block goes down significantly. And the way to solve that
- 1:10:20problem is to aggregate hash rate. You get a bunch of these smaller miners and now large miners as
- 1:10:27well. They basically aggregate their hash rate in what's known as a Bitcoin mining pool.
- 1:10:32And that mining pool is essentially tasked with aggregating the hash rate. And then you have all
- 1:10:39these individual actors within the pool producing hashes one of those actors will find the hash
- 1:10:46that enables them to add a block to the ledger and get the reward and the pool does the job of
- 1:10:53basically accounting for who's pointing hash at their pool at one point in time how much hash rate
- 1:11:01and how much of the reward each individual miner gets
- 1:11:07based off of the amount of hash rate they're pointing at the pool.
- 1:11:10So a pool exists to increase variance.
- 1:11:13And so when you hear of individual miners mining their own blocks
- 1:11:19and building a big Bitcoin stack in 2009, 2010, that doesn't happen anymore.
- 1:11:23It's a bunch of individual miners pointing at a pool.
- 1:11:26And even if your individual miner finds a hash,
- 1:11:30you're basically saying I'm going to
- 1:11:32lower my variance
- 1:11:34by pointing at this pool and I'm going to split the reward
- 1:11:36among all the
- 1:11:38miners pointing at that particular pool
- 1:11:40so if I'm a miner and I represented
- 1:11:42a hundredth of the network
- 1:11:44I would
- 1:11:46solve a block
- 1:11:48like one block
- 1:11:49a day but
- 1:11:51if I represented a thousandth
- 1:11:54of the network then
- 1:11:56it would take me several days
- 1:11:58to potentially find a block on my own.
- 1:12:00And if you kind of go smaller and smaller,
- 1:12:02and as the Bitcoin network gets larger and larger,
- 1:12:04while there are exceptions,
- 1:12:06it becomes more difficult to be
- 1:12:08a large enough percentage on the network
- 1:12:12to reliably get paid out.
- 1:12:15If you have expenses that you're paying out in the interim,
- 1:12:17it might require you to have more capitalization,
- 1:12:21more working capital on hand,
- 1:12:23and just creates a strain operationally.
- 1:12:26And so for that reason, pools began to emerge to allow people to effectively get paid out more regularly, reduce variance.
- 1:12:38It's difficult to capitalize mine as it is, reducing the working capital requirements potentially of a Bitcoin mine.
- 1:12:47So now describe current state of centralization in mining pools and why in your view it exists.
- 1:12:57To do this, we have to go back in time as well.
- 1:13:00When pools first came out, the predominant payout scheme is called PPL and LNS, pay per last end shares.
- 1:13:11and basically in that
- 1:13:13mining pool
- 1:13:15payout model
- 1:13:17you would point your
- 1:13:19hash at a pool and then
- 1:13:22whenever that pool would
- 1:13:23find a block
- 1:13:24you would get your
- 1:13:27commensurate amount of the reward and you get
- 1:13:29paid out when they found the block
- 1:13:31they would find a block and then you get
- 1:13:33paid out from that reward
- 1:13:34and as the network grew
- 1:13:38and more pools came to market
- 1:13:39like the variance of individual pools began to grow and extend as well And so the predominant model that has really taken over within bitcoin mining pools the payout model is fpps full pay per share and essentially what full pay per share pools
- 1:14:00have created is a system where they say point your hash rate at our pool we'll do like a moving
- 1:14:09average of how much hash rate how much blocks we produced and we'll pay you out uh a consistent
- 1:14:15amount every day we'll pay out once a day based off of that moving average um so you have more
- 1:14:21consistent revenue you're not beholden to the very so functionally pools help reduce variance but
- 1:14:26then the fpps the fixed paper share further reduces variance by giving a miner a predictable
- 1:14:34daily amount of revenue why has that caused centralization so that's caused so you have
- 1:14:42two trade-offs the ppl and s what was predominant um in the early years of pooling the trade-off
- 1:14:49there is you're going to as an individual miner you're going to get you know you're going to get
- 1:14:56like the full reward of that block that's mine because as it's not as it's not as um
- 1:15:02uh it's not as relevant right now because there's not a lot of fees but like if we're in a high fee
- 1:15:09environment and the variability of block rewards is is pretty high because fees are variable um
- 1:15:18from block to block like let's in a ppl and s model like if your pool mines a block with a very
- 1:15:26high fee like you want to get that whole reward and so like that's the trade-off you make in ppl
- 1:15:32and s is like i'm gonna get the whole reward of that block but i'm gonna stomach more variance
- 1:15:36because it's not like that pool could have a string of bad luck where instead of finding three blocks
- 1:15:43a day they find um they find three blocks over three days and so you're you're getting less
- 1:15:48consistent payouts but you're reaping the full reward of those individual payouts f pps fixed
- 1:15:55pay per share um again since it's the moving average of the individual block let's say the
- 1:16:01pool mines a block with a fat fee like they're just going to use the moving average in their
- 1:16:05calculations you're going to get paid out and you're not going to get the full reward but you're
- 1:16:09getting paid out every day and this creates uh an accounting problem for the pools and a capital
- 1:16:17problem specifically so for the fpps pools the fixed pay per share pools to be able to do this
- 1:16:23What they need is a big Bitcoin treasury that they can actually use.
- 1:16:30They essentially use as a credit line.
- 1:16:32They're absorbing the variance risk as the pool.
- 1:16:35And so you need a big Bitcoin treasury to pull from to consistently pay out.
- 1:16:40Because even as an FPPS pool, you can have strings of bad luck where your variance increases and elongates.
- 1:16:46And if you're running an FPPS pool where you have a pretty long string of bad luck, you could run out of Bitcoin in your reserves and you cannot pay out.
- 1:16:56And so that over the last two years, it's become clear that that mechanism has become a very centralizing aspect of the Bitcoin mining pool industry.
- 1:17:06Because what we've found is that last year, Matt Corralo and others started ringing the alarm bell.
- 1:17:12It became clear and a lot of on-chain analysts like OXT and Zero XT were basically observing that the block templates of different FPPS mining pools were exactly the same.
- 1:17:28and so essentially what was discovered
- 1:17:31is that you had a number of
- 1:17:33FPPS pools run into that
- 1:17:36treasury problem
- 1:17:37where they didn't have enough Bitcoin
- 1:17:40to pay out and so they were forced to go
- 1:17:41hat in hand to Antpool
- 1:17:44which is essentially a subsidiary
- 1:17:46of Bitcoin
- 1:17:46basically
- 1:17:47mining pools that were
- 1:17:51attempting to
- 1:17:53deliver
- 1:17:56the product that they thought
- 1:17:58would allow them to acquire minors as customers,
- 1:18:02being able to pay out a consistent amount each day,
- 1:18:07were not well capitalized,
- 1:18:08and they were absorbing the financial risk.
- 1:18:11And then ultimately, they got exposed.
- 1:18:16Whether they went belly up,
- 1:18:18they realized that they couldn't absorb that risk,
- 1:18:20and they went up the food chain to companies
- 1:18:23that had larger balance sheets.
- 1:18:25And then, essentially, it becomes a game
- 1:18:27that if you are not,
- 1:18:29you know,
- 1:18:30I don't know if irony is the term,
- 1:18:31but it's like the same risk exists
- 1:18:33with these larger guys
- 1:18:34that are just aggregating more hash rate.
- 1:18:35It's like they're bearing this financial risk
- 1:18:37and they could be exposed
- 1:18:39as not being financially solvent
- 1:18:42should a stretch of bad luck
- 1:18:45emerge for an extended period of time.
- 1:18:49In the case of Ample,
- 1:18:50I think it would have to be
- 1:18:52a very, very long,
- 1:18:53like statistically impossible.
- 1:18:56Yeah, and I'm going to spend time
- 1:18:57like digging into this like like the differences between a paper last and shares different forms of
- 1:19:05that fixed paper share some of the economic incentives that might not be as well understood
- 1:19:10in terms of how you know you're basically trusting fpps pool in terms of what the
- 1:19:15pool is actually generating how these are actually accounted for distributed we'll go into that
- 1:19:21in other episodes, but just articulate
- 1:19:24what, as a percentage basis,
- 1:19:27does that ecosystem look like
- 1:19:30to not lose people in the weeds?
- 1:19:33The last time I saw the...
- 1:19:35I think to describe it more thoroughly,
- 1:19:38Ampoule, essentially a subsidiary Bitmain,
- 1:19:42and over the course of more than a decade...
- 1:19:43So that's the point of centralization,
- 1:19:44is that these entities are related.
- 1:19:46Yeah.
- 1:19:48They have a large Bitcoin war chest.
- 1:19:51And this is actually like when it comes to this pool problem, I don't think we're going to solve it here on this episode, but maybe we can do another one where I think when you look at pools are, if you think Bitcoin mining, like just like plugging in ASICs and running them as an operation, like locking down the energies, competitive pools are terrible businesses.
- 1:20:09so people say this pools are terrible businesses but they are necessary to the operation of bitcoin
- 1:20:16mining and so one of the questions that i have is it's like
- 1:20:21maybe it's just a cost center to a business but is it specialized enough to merit being
- 1:20:28its own business and i don't think so the switching cost is zero like that's like you don't
- 1:20:34what I'm saying
- 1:20:37it's a necessary
- 1:20:39in order to mine
- 1:20:40you essentially
- 1:20:41either have to be
- 1:20:41your own pool
- 1:20:42or you have to join a pool
- 1:20:44the pool function
- 1:20:46is critical
- 1:20:47so
- 1:20:48how can
- 1:20:49the pool business
- 1:20:51be a bad business
- 1:20:51if it's
- 1:20:52it's critical
- 1:20:53if it's delivering
- 1:20:54both the service
- 1:20:55and being critical
- 1:20:55to the
- 1:20:57because you can just
- 1:20:58I mean I think
- 1:20:59Apple is a great
- 1:20:59they can just
- 1:21:00they can just
- 1:21:01set their costs
- 1:21:04such that you can't compete right because they have this large and so this might because they're
- 1:21:09well capitalized they're extremely well capitalized like they have a large bitcoin treasury they have
- 1:21:13the hardware business essentially that doesn't that doesn't say that being a mining pool is a
- 1:21:19bad business it just might say in order to be a good pool you need to be very well capitalized
- 1:21:26if fpps is the right model which i have i have questions about myself i don't think it's the
- 1:21:32right model but i do think okay go on yeah like i think looking at bitmain and ample and their
- 1:21:40relationship i think that's something people should really pay attention to and try to
- 1:21:45internalize like you have this behemoth of bitmain and their hardware sales which is incredible
- 1:21:50business um cash flows a lot like and are they anti-competitive bitmain just going back to the
- 1:22:01like are they actively in the background trying to prevent other i wouldn't be surprised i mean
- 1:22:08i don't know for sure but just if they're economically rational actors i wouldn't be
- 1:22:14surprised that they are preventing others from getting access to the foundries that they work
- 1:22:18with yeah all right that was just an aside but sorry i didn't mean to distract from the
- 1:22:22no i think like running a pool like you may need another like pools i think we need to rethink
- 1:22:28like how pools come to be how they operate like is a pool a loss leader for somebody doing something
- 1:22:37like basic manufacturing or um your bitcoin exchanges maybe they should like if maybe they
- 1:22:45should be running pools to some extent um just as a way to decentral like if you're an exchange and
- 1:22:52you're thinking about the long-term viability of your business and that sort of the prerequisite
- 1:23:00for that long-term success is bitcoin being sufficiently decentralized and block production
- 1:23:05being decentralized like does it make sense for you to spin up a pool to give people an option to
- 1:23:10um you know i'm not saying this is the right answer but just like thinking through this like
- 1:23:15pools is a pure play business model i don't think makes sense like you need another part of that
- 1:23:21business to sort of make sure it's well capitalized and historically you've seen this with bitmain
- 1:23:27and ampoule via the asex sales and then other pools like luxor and brains with firmware that
- 1:23:34makes the machines more efficient and they charge a cost for that and the cost is worth it because
- 1:23:39the efficiency gains are such that you will pay a fee for it and you get revenue that way
- 1:23:45or do we just need to completely rethink it and and how like what businesses should be spinning
- 1:23:51up pools um to to ensure that there's sufficient distribution of block creation between different
- 1:24:00actors does that make sense yeah that makes sense and then but then to provide this the most summary
- 1:24:06level view we have actually ant pool that's that's based in china right and they're functionally
- 1:24:15they're basically saying hey oh but i want to connect this for people that there are probably
- 1:24:20based on what you said about that corral and others who realize how are we doing on time logan
- 1:24:25and we're good that amp pool is essentially a um proxy for 10 or so other pools such that
- 1:24:34you're looking at those other pools and and they look like individual pools but
- 1:24:40they're really a proxy for amp pool they're really a proxy for ample amp pools creating the templates
- 1:24:46but so if you add up
- 1:24:48camp pool
- 1:24:49and the other pools
- 1:24:51it's like 60 to 70%
- 1:24:53and then
- 1:24:54boundary
- 1:24:55which is US based
- 1:24:57yeah so it's not 60
- 1:24:58it's probably like 50 to 60
- 1:25:00yeah
- 1:25:00yeah 50 to 60
- 1:25:02maybe like 50
- 1:25:03boundary is like 25 to 30%
- 1:25:06yeah
- 1:25:06and then marathon
- 1:25:08which is a solo
- 1:25:09a little bit of a large scale minor
- 1:25:11you have other
- 1:25:11which is around like 12
- 1:25:12so
- 1:25:13so
- 1:25:14three functional pools
- 1:25:16including one solo miner,
- 1:25:18and I know that other small miners use Marathon's pool,
- 1:25:23but functionally the pool of one,
- 1:25:26that three pools represent about 90% of the hash rate.
- 1:25:33What is the present risk to the Bitcoin network functioning
- 1:25:38that comes from that?
- 1:25:41It's probably going to sound controversial,
- 1:25:44but I think zero.
- 1:25:45again going back to
- 1:25:46describe why you view it as zero
- 1:25:49but then
- 1:25:51make the other argument
- 1:25:52I think it's zero because the switching cost
- 1:25:55is zero and if push comes to show
- 1:25:58if we've seen this already
- 1:25:59in Bitcoin's history in 2016
- 1:26:02there was a pool called GHash
- 1:26:03that was ultimately a victim
- 1:26:06of its own success
- 1:26:07it aggregated as a
- 1:26:10single pool 55%
- 1:26:12of the network hash rate
- 1:26:14people on bitcoin talk.org and twitter were like yo g hash has 55 this is a threat to the network
- 1:26:21if they wanted to 51 attack the network they could and within days it fell from 55 to 20
- 1:26:29and over the course of 18 months after the alarm bells went off g hash was out of business um so
- 1:26:35miners individual hash owners that are economically incentivized to ensure that their golden goose
- 1:26:42isn killed by centralization reacted to those centralization pressures Right So I get why you know it not in the interest of mining pools or miners to 51 attack Bitcoin
- 1:26:58network that would be putting at risk there.
- 1:27:02The thing that they exist.
- 1:27:04No,
- 1:27:04but the real risk is you could,
- 1:27:08you could have censorship or they could try to reorg via 51% attacked.
- 1:27:14but what about the angle of the three minor three mining pools all being on the same page
- 1:27:19about consensus changes that are not hard for us um
- 1:27:28this is where we get into like this is where we get into like murky territory of like what actually
- 1:27:34is needed to like what actors are needed to
- 1:27:40actually get a software change into bitcoin and
- 1:27:45that's like block size wars what was it was a bit 91 was a bit 148 like but in that case that
- 1:27:54was actually a non-backward compatible change i'm talking about a in in the block wars increasing the
- 1:28:02block size to two times would have you would have forked off the network and bitcoin cash did
- 1:28:08right but and so but that was that that presents a different dilemma versus a soft fork and if
- 1:28:18if all three the large mining pools agree on what change should be and they're not forking
- 1:28:27themselves off from the network then if you're a miner and you're hashing you functionally can't
- 1:28:34switch between
- 1:28:34if there's
- 1:28:36collusion
- 1:28:37and this gets
- 1:28:38like who
- 1:28:38dictates the
- 1:28:39rules right
- 1:28:40because like
- 1:28:40if you're
- 1:28:41well but like
- 1:28:43as an example
- 1:28:43let me let me
- 1:28:44like throw a
- 1:28:44different scenario
- 1:28:45say bitcoin
- 1:28:46core
- 1:28:46um
- 1:28:48wants to
- 1:28:52merge a
- 1:28:55software
- 1:28:55and three
- 1:28:56mining pools
- 1:28:57agree
- 1:28:59is that a
- 1:29:02risk
- 1:29:02could be
- 1:29:04but what if
- 1:29:06like economic
- 1:29:09actors
- 1:29:10and I say a risk
- 1:29:11to like
- 1:29:11a relatively few
- 1:29:12number of people
- 1:29:13you would need
- 1:29:14buy in from
- 1:29:15other actors too
- 1:29:17like exchange
- 1:29:18like big economic
- 1:29:19actors
- 1:29:19that aren't mining
- 1:29:20like exchanges
- 1:29:21and
- 1:29:22people that are
- 1:29:23transacting a lot
- 1:29:24on the bitcoin network
- 1:29:25to download
- 1:29:26that node software
- 1:29:27like you could see
- 1:29:28a scenario where
- 1:29:29but it would be
- 1:29:30backward compatible
- 1:29:31right
- 1:29:33and the miners
- 1:29:37would be enforcing the rules and that would be the
- 1:29:39longest chain
- 1:29:40anyways we'll dive more into these in these topics
- 1:29:47the
- 1:29:48I'm trying to think through this
- 1:29:53because
- 1:29:53again going back to like BIP 91
- 1:29:57BIP 148 like what was the actual
- 1:29:59sort of forcing function for segwit getting implemented into bitcoin i mean that was is
- 1:30:07there a scenario it's backward compatible but like let's say coinbase says like i don't like this
- 1:30:17or river strike combination of all those guys you have like this battle between these large
- 1:30:24economic transactors
- 1:30:25and the miners
- 1:30:26like could
- 1:30:27I mean I think
- 1:30:29my understanding
- 1:30:30is they would
- 1:30:30continue
- 1:30:31they wouldn't have
- 1:30:32to change anything
- 1:30:33they would be accepting
- 1:30:34all of the transactions
- 1:30:35that are on the more
- 1:30:35restricted as well
- 1:30:36but even if it's
- 1:30:37backward compatible
- 1:30:38nobody's running
- 1:30:39if the mining pools
- 1:30:40are advancing
- 1:30:41the longest chain
- 1:30:42yeah but like
- 1:30:43if nobody
- 1:30:44still if it's back
- 1:30:45yeah maybe
- 1:30:46there's not a functional
- 1:30:47there's nobody using it
- 1:30:49yeah
- 1:30:49like
- 1:30:50that
- 1:30:51that would
- 1:30:52de-risk it
- 1:30:53yeah
- 1:30:53like hey if
- 1:30:54if nodes aren't transmitting
- 1:30:56transactions that
- 1:30:57conform but then that would
- 1:30:59kind of
- 1:31:01they just never download
- 1:31:04the version like
- 1:31:05then we get an all like sort of rough
- 1:31:08consensus dynamics like somebody's actually got to build
- 1:31:10write the
- 1:31:12software that the miners want
- 1:31:14or that
- 1:31:17core wants or core is like
- 1:31:19core is not some
- 1:31:21centralized entity
- 1:31:23all right i'll shift the question this is where like the beauty of of bitcoin rough consensus
- 1:31:28comes yeah and we'll and again we're not going to solve all the you know knowledge base of
- 1:31:32bitcoin in a single episode but um one last thing on this piece and then we'll wrap up which is um
- 1:31:40it's not in the interest of bitcoin miners the ones that like if you think about the supply chain
- 1:31:45it's some natural resource that is storing energy being converted to electricity that's creating a
- 1:31:53hash that an aggregate is enforcing Bitcoin's fixed supply and validating all currency transactions.
- 1:31:59Those hashes are pointed at a pool and blocks are processed during the fixed supply.
- 1:32:07Bitcoin network is working going forward.
- 1:32:10It's not in the interest of the miners actually producing the hashes that the pools are centralized.
- 1:32:18what in your mind changes the dynamic that would create a scenario for greater decentralization
- 1:32:29i think
- 1:32:32stuff like this is great where you have sort of at-home mining and as we reach asa commodification
- 1:32:43and the waste heat can be used for services
- 1:32:46like heating water in your house,
- 1:32:48using the waste heat to heat your house itself,
- 1:32:52that acts as like a natural...
- 1:32:54But is that a view that, you know,
- 1:32:56if Riot is working on a gigawatt site,
- 1:33:00that large-scale Bitcoin mines
- 1:33:05are ultimately long-term not as viable and that...
- 1:33:09Yeah, like I think Riot, like I love...
- 1:33:13everybody at these companies but like at the end of the day like i'm just saying if this is how
- 1:33:17bitcoin decentralizes it would it would or you know decentralizes decentralizes from the point
- 1:33:24of centralization as it relates to pools and that would suggest that you know any any bitcoin mine
- 1:33:34of scale becomes less competitive for some reason that i couldn't gather if the cheapest way to
- 1:33:41produce a um a unit of power is with large power plants
- 1:33:47the say that again that the the cheapest unit of power is at scale with a either combined cycle
- 1:33:59turbine or a nuclear power plant or even something like a large solar generator yeah at scale
- 1:34:10they're going to be the cheapest but you know like in the wasted example for like at-home
- 1:34:15applications like you're usually you're basically using bitcoin mining to subsidize to lower your
- 1:34:21your month-to-month electricity bill and actually produce some revenue whether or not you're willing
- 1:34:27to stomach the variance is up to the individual but i think what's most important is we can dive
- 1:34:34deep on the pool stuff and the industrial size miners but i think what i care about most is the
- 1:34:43decentralization of hash rate ownership and as many like you're gonna have obviously a spectrum
- 1:34:49of people owning one asic chip like one terahash to multiple tens dozens of exahash but as long as
- 1:35:00sort of distribution of individual owners across that spectrum is is robust i think it'll be
- 1:35:07sufficient to ensure that mining is decentralized at the end of the day and yeah we'll have to
- 1:35:13explore this more because i i or explore this more because
- 1:35:16it's like that hash rate continues to to naturally decentralize because
- 1:35:22energy is distributed all to the world it seems like there's a disinterest
- 1:35:27or there should be a disincentive of of all this very distributed hash rate pointing to
- 1:35:35a regulatory and otherwise censorship prone points of centralization being pools
- 1:35:45that there would there would need to there would almost and again i want to explore i don't know
- 1:35:49what it is a natural forcing function for miners to realize that there's an there's an interest
- 1:35:57in an incentive for pools not to be nearly as centralized yeah and going back to what i was
- 1:36:06saying earlier like maybe it's not even the mining industry that comes up with the solution maybe it's
- 1:36:10some other sort of actor with a ton of skin in the game that recognizes this as a risk and has
- 1:36:16a profitable business and decides to spin up a mining pool to counteract
- 1:36:20the centralizing factors. I don't have the answers to this, but I do
- 1:36:24think I've identified at least one thing, which is
- 1:36:28we need to completely rethink how mining pools
- 1:36:30come to market and how they operate.
- 1:36:37We're getting a bit doomer-ish here. It's important
- 1:36:40to understand these risks and where the centralization lies,
- 1:36:44But ultimately, at the end of the day, I think the incentives of Bitcoin as a project overall and individual actors within a mining ecosystem are aligned to the point where the problem will be solved.
- 1:36:58I don't know exactly what the solution is, but I'm just confident in the economic incentives.
- 1:37:04And as Bitcoin continues to increase in price, those incentives only get stronger.
- 1:37:10Right. And that's something that we're going to talk about as well.
- 1:37:14on other episodes, like you said, the incentives of Bitcoin.
- 1:37:18And I think that if we think about just this first episode
- 1:37:22and where we plan to take this show part of TFTC,
- 1:37:30is exploring the entire value chain down to the molecules.
- 1:37:39From the molecules to the conversion of power,
- 1:37:41how Bitcoin intends, not intends, how Bitcoin solves real world energy problems, how that
- 1:37:48changes as Bitcoin's demand for energy scales, why or why it won't increase in energy demand
- 1:37:55over time or what the drivers will be, how that will evolve.
- 1:37:59Points of centralization, how Bitcoin mining works of past the point of natural resources
- 1:38:07of being converted into electricity
- 1:38:08and the role of ASICs, the role of pools.
- 1:38:12But one of the things that I found
- 1:38:15legacy energy industry struggles with
- 1:38:21or someone like a grid operator
- 1:38:22or legislators or regulators
- 1:38:24is all this power demand sustainable.
- 1:38:27And I'm not talking about
- 1:38:28from an environmental perspective.
- 1:38:30I'm talking about from-
- 1:38:32Are people going to want to Bitcoin mine 10 years from now?
- 1:38:34Yes.
- 1:38:35and what causes that
- 1:38:37and will it be sustained
- 1:38:39because if you develop,
- 1:38:41say as a grid operator,
- 1:38:43an energy reliability strategy
- 1:38:46around 4 gigawatts of power
- 1:38:49growing to 8,
- 1:38:50growing to 10,
- 1:38:51growing to 20
- 1:38:51and there's the possibility
- 1:38:53it could all go away,
- 1:38:55that's a source of risk.
- 1:38:57And what you just described was
- 1:38:59you said,
- 1:39:00if price continues to go up,
- 1:39:03then all of these other things will follow more demand for power or decentralization or entrance
- 1:39:12and i just want to connect for the audience and all the bitcoiners know this but it's that
- 1:39:19that price increasing is a function of more people deciding to store their value in bitcoin
- 1:39:28and the thing that holds it all together is bitcoin's fixed supply and its ability to
- 1:39:36operate in a way that is censorship resistant to censorship which is dependent on progressive
- 1:39:43decentralization at every level there of bitcoin such that so long as those two things hold that Bitcoin fixed supplies enforce and it remains permissionless and resistant to outside censorship all those
- 1:39:57things happen.
- 1:39:58And those are the things that we'll just discuss and explore in greater detail.
- 1:40:04But knowing that it's all anchored to the monetary side, because it's kind of a turtles
- 1:40:09all the way down problem.
- 1:40:10And I want to kind of get your thoughts on this as kind of a concluding thought.
- 1:40:14And I'll have one last question, which is the thing that ties the demand for the hashes and the demand for power comes back to Bitcoin and the incentives of the Bitcoin network.
- 1:40:28Just talk about the incentives of the Bitcoin network itself and the fixed supply and its downstream impacts throughout the mining and power dynamics.
- 1:40:39yeah and going back to what i said in the beginning of the episode bitcoin is not even an attempt it's
- 1:40:46successfully separated money from state so bitcoin exists because satoshi recognized that
- 1:40:54we keep running into these problems um societally because governments and central banks can print
- 1:41:01money at will and there needs to be a market response to the centralized control over
- 1:41:09money and that's what bitcoin represents and so there's a ton of value in being able to successfully
- 1:41:15separate the the function of money itself and um the control over uh the units of that money that
- 1:41:26exists at any given point in time and so that is what bitcoin is is we finally figured out a way
- 1:41:33to get the central authorities out of money they're not meddling with it anymore in bitcoin
- 1:41:41which is incredibly valuable um there will only ever be 21 million and people can have certainty
- 1:41:47that if they store their value in bitcoin their slice of the overall pie um even though it's very
- 1:41:55divisible it doesn't mean you're producing more bitcoin like if you own one bitcoin you own one
- 1:42:0121 millionth of the network into perpetuity and there's a ton of value in having that certainty as
- 1:42:09an individual as a company as a government even um and so that is essentially what ties all this
- 1:42:17together is having that certainty that if you store your value in bitcoin it's not going to be
- 1:42:22debased and as more people recognize this it just perpetuates the feedback loop that you just
- 1:42:28described and that is worth preserving and people who are storing their big their value in bitcoin
- 1:42:35will fight to ensure that those properties remain distributed so that the money cannot be meddled
- 1:42:41with in the future yeah and so it's like one one or for episode one parting takeaway for
- 1:42:50if you were an energy professional who doesn't understand why there's four gigawatts of power
- 1:42:57being drawn in Texas to mine Bitcoin
- 1:43:01in 30 gigawatts globally
- 1:43:04and get lost in hashes and ASICs
- 1:43:07and mining pools.
- 1:43:09The reason for its existence
- 1:43:11and the reason why it will be sustained
- 1:43:13is Bitcoin delivers sound money.
- 1:43:16The fixed supply is the anchor of that.
- 1:43:18It is solving the problem
- 1:43:19that every other form of money
- 1:43:20is dependent on trust.
- 1:43:22And through this function of mining
- 1:43:23is how the Bitcoin network
- 1:43:27can credibly enforce as fixed supply in a trustless way without reliance on that central
- 1:43:31third party.
- 1:43:32But then for the Bitcoin miners and the people that are well immersed is that all that only
- 1:43:36works because of decentralization.
- 1:43:39And that if there's complacency of points of centralization, even though there are economic
- 1:43:44incentives that will dictate progressive decentralization, that that only happens by
- 1:43:51individual actors within the network
- 1:43:54responding to incentives
- 1:43:57that contemplate that idea
- 1:43:58that points of centralization
- 1:44:00are not just
- 1:44:03risks to the network, but they
- 1:44:04are risks to the individual actor acting
- 1:44:06in their own self-interest.
- 1:44:08Yeah. And so that's
- 1:44:10complacency and apathy
- 1:44:11will,
- 1:44:14if you're a minor, ruin your business
- 1:44:15in the long run because you'll
- 1:44:17invest in all this infrastructure
- 1:44:19and you'll
- 1:44:21put all this time and effort into it and if you get too complacent too apathetic and you just
- 1:44:25hand wave like oh this is okay um and bitcoin becomes centralized and uh people are easily
- 1:44:32able to push changes that increase the supply or do something that makes it harder to run bitcoin
- 1:44:37distorts the economic incentives yeah you're basically just setting your capital on fire
- 1:44:44because as an individual saving in bitcoin if that happens i'm like oh shit like back to gold
- 1:44:50like the so and that's why like i'm sorry if it was like hand waving a little bit um flippant
- 1:44:59earlier but like i i do believe the incentives are strong enough and people um will be forced
- 1:45:07to reckon and that's what we we saw like in the block size war in 2017 when things are threatened
- 1:45:12people react and we saw it with g hash in 2015 like that okay we enter these periods where you
- 1:45:21have relative peace time but in my experience being in bitcoin for 12 years whenever something
- 1:45:26controversial or something a threat to the sanctity of bitcoin the protocol and how it operates has
- 1:45:33ever arisen like the economically incentivized individuals leveraging bitcoin or involved in
- 1:45:39bitcoin like stand up so you know like you're not doing this yeah the the the threat needs to
- 1:45:44present itself and in a lot of cases for and it to be clear and present for a real immune response
- 1:45:52to kick in while at the same time everyone's acting in their own self-interest and there's
- 1:45:58a natural tie-in to um de-risking yourself from other counterparties yep whether that's storing
- 1:46:06Bitcoin with an exchange and that might mean having other exchange options or having more
- 1:46:11self-custody options or whether you're tied into a certain vendor or on the mining side,
- 1:46:16being tied into a pool or having limited options to shift around or who you are sourcing from in
- 1:46:24terms of a supplier that throughout the ecosystem, everyone has an incentive to be less reliant
- 1:46:32on potential points of failure yeah all right last question
- 1:46:37two subjects related to energy or mining that you're most interested in us diving deeply in
- 1:46:46on this podcast and then give me your top five wish lists of guests okay um at home mining like
- 1:46:56waste heat
- 1:46:57I think people are sleeping on that
- 1:47:02trend Tyler Stevens
- 1:47:04and what they're trying
- 1:47:08to do like he wrote the book with
- 1:47:10brains on waste heat like the stat he threw out
- 1:47:12earlier this year at the Nashville
- 1:47:15Energy and Mining
- 1:47:16Summit was mind-blowing if you take
- 1:47:182% of the
- 1:47:20HVAC market globally and
- 1:47:22you successfully convince
- 1:47:242% of that market running
- 1:47:26HVAC systems to incorporate Bitcoin mining
- 1:47:29you would like double the hash rate
- 1:47:31overnight just like that's
- 1:47:33that minute market share
- 1:47:35we'll get Tyler on
- 1:47:37so he'll be one of your top five
- 1:47:39incorporating
- 1:47:40yes incorporating
- 1:47:41mining into the home applications
- 1:47:47basically subsidize your energy cost
- 1:47:49by producing Bitcoin
- 1:47:51I think it'd be massively beneficial
- 1:47:53to
- 1:47:54decentralization of the network and really uh hashrate ownership overall and you can think of
- 1:48:02like hvac like maybe individual hvac companies run pools where their customers are pointing their hash
- 1:48:07at the hvac pool that they're using and that's how you get mining pool decentralization that's
- 1:48:14like at home sort of like home application of mining using the waste heat something that
- 1:48:19i'm very excited about and i think we've reached a point of basic commodification where you can
- 1:48:23begin to build viable businesses around so that's one the other would be
- 1:48:35the midstream problem I think like getting a midstream operator on here
- 1:48:41hopefully one that actually understands a coin mining and is like on top of it
- 1:48:49like how that actually works because it was a thesis we had i talked to some people that are
- 1:48:54saying that the thesis is being validated and they're actually doing it and i think at scale
- 1:48:59that would be massive for the natural gas supply chain and bitcoin mining overall i got some ideas
- 1:49:04as people that uh the bitcoiners would have never heard of so yeah um top five tyler on um
- 1:49:13toby rice from uh the eqt the biggest natural gas producer
- 1:49:19I had the pleasure of sitting out at dinner with him like two or three years
- 1:49:23ago.
- 1:49:25And I don't know him.
- 1:49:26He's a,
- 1:49:27see,
- 1:49:27uh,
- 1:49:28where is he on the Bitcoin spectrum?
- 1:49:30He was,
- 1:49:30uh,
- 1:49:30it was,
- 1:49:33this was like peak 21 craze.
- 1:49:35So he was talking like she and a bow and like meme coins and all.
- 1:49:37I was like,
- 1:49:38Joe,
- 1:49:38like just focus on Bitcoin.
- 1:49:40Um,
- 1:49:42that'd be a good one.
- 1:49:43Uh,
- 1:49:43Chris Ray or excuse me,
- 1:49:45Chris Wright.
- 1:49:46They had an FBI.
- 1:49:47Chris Ray was the FBI.
- 1:49:48I always get to mix up Chris,
- 1:49:49right?
- 1:49:49uh,
- 1:49:51department of energy.
- 1:49:52I've had him on my podcast a couple of times in the past.
- 1:49:57It'd be great to catch up with him.
- 1:49:59Um,
- 1:50:00do you see the energy things?
- 1:50:02Yeah.
- 1:50:02Yeah.
- 1:50:03Your secretary of the department of energy.
- 1:50:05Yeah.
- 1:50:07Uh,
- 1:50:08Elon,
- 1:50:09you got to get Elon.
- 1:50:10I mean,
- 1:50:10Jesse Pelton,
- 1:50:11maybe,
- 1:50:11maybe like one degree away from,
- 1:50:13I want to do a,
- 1:50:14I think I,
- 1:50:15and I'll admit,
- 1:50:15I want to do a residency with Jesse on like,
- 1:50:18like,
- 1:50:18like,
- 1:50:19on the physics of energy.
- 1:50:21Yeah.
- 1:50:21And then how that comes through a bit quite a good Jesse.
- 1:50:26And then,
- 1:50:27uh,
- 1:50:27Nick Gates,
- 1:50:28I think,
- 1:50:28um,
- 1:50:30Nick is a priority power.
- 1:50:32He's,
- 1:50:33yeah,
- 1:50:33he's,
- 1:50:33I think he's my,
- 1:50:34he's my go,
- 1:50:35he's within my handful of go to people of,
- 1:50:38as I'm trying to understand the grid and energy systems,
- 1:50:42energy markets,
- 1:50:42he's one of my go-tos.
- 1:50:44Yeah.
- 1:50:45And then,
- 1:50:45you know,
- 1:50:46he always,
- 1:50:48um,
- 1:50:49He helps sharpen my views of everything around Bitcoin.
- 1:50:54I feel like I've helped him understand Bitcoin better.
- 1:50:56I don't know their names, but one of the founders of an SMR company like Oklo.
- 1:51:03You have to give me another name, but I'll get that as a sub.
- 1:51:06So SMRs are small modular reactors on the nuclear side.
- 1:51:10But another name.
- 1:51:11You've given me five.
- 1:51:14Tyler Stevens, Toby Rice, Chris Wright, Jesse Pelt, and Nick Gates.
- 1:51:18Yeah.
- 1:51:18Yeah.
- 1:51:19start with some of those well i'm very excited for your consistency is key
- 1:51:24yeah we're gonna be recording in the podcast studio podcast production is is a grind okay
- 1:51:30i'm gonna be on top of this i got strong team it's one of the reasons why we're working with tftc
- 1:51:34have beautiful studio here in austin texas great team we've got a mute all the infrastructure
- 1:51:40perspective great feed yeah we're gonna we're gonna you know rely on logan's uh fact-checking
- 1:51:47us from time to time he's gonna fact check thumbs up okay that video that logan did uh when he was
- 1:51:57what was the video you were selling uh some class i i was like i didn't even know logan can act he
- 1:52:06can act he can dance you know got some jokes the right way yes yeah so i'm happy for you
- 1:52:12yeah
- 1:52:13put your sign off
- 1:52:13that's a big thing
- 1:52:14I'm not doing
- 1:52:15I don't know
- 1:52:16gotta think about that
- 1:52:18I'm just gonna copy you
- 1:52:20with a final thought
- 1:52:21we're gonna zoom out
- 1:52:22from the center of hash
- 1:52:23I don't know
- 1:52:25are we going with center?
- 1:52:26that's all folks
- 1:52:27nah that was Bugs Bunny
- 1:52:28or
- 1:52:29is it the pig
- 1:52:30Porky the pig
- 1:52:31I don't know
- 1:52:32think about it
- 1:52:33we gotta figure out the name
- 1:52:37first in the next
- 1:52:38few days before we release it
- 1:52:40hash found
- 1:52:40next block
- 1:52:41don't know
- 1:52:43yeah
- 1:52:43alright we'll just end it
- 1:52:46till next time
