In today's episode we cover the "blockchain trilemma" - Vitalik Buterin's concept of three primary attributes of a blockchain:
Any blockchain in development has to make compromises between these three aspects. They simply can't have the best aspects of all three attributes. We discuss each of these and how they relate to some of the most popular blockchains with an eye towards enabling you to evaluate any blockchain's chances of long-term success.
Hey everyone, no one on this podcast is a financial advisor all the information presented on this podcast is for
Speaker:Informational purposes only now that we have the legal stuff out of the way. Let's jump on in
Speaker:Welcome to the generational wealth cryptocurrency podcast. I'm your host McIntosh and today we're going to be talking about the
Speaker:blockchain trilemma
Speaker:What's the blockchain trilemma? The blockchain trilemma was a phrase that was
Speaker:coined by Vitalik Buterin who is the
Speaker:founder of
Speaker:Ethereum and very well-versed certainly in blockchain technology really smart guy
Speaker:basically this phrase was a way to
Speaker:highlight the three main issues that developers deal with when building a new blockchain whether that was Ethereum
Speaker:back when it started in 2015 or
Speaker:Solana which just came out this year or
Speaker:Bitcoin back in
Speaker:2009 although certainly they probably didn't have a well
Speaker:Satoshi was a really smart guy, but certainly
Speaker:Now that this has been around for a while
Speaker:There's been a lot of discussion about this and basically any blockchain has to deal with these three aspects and there are trade-offs
Speaker:You can't there's no blockchain that's going to perfectly implement all three of these
Speaker:So we're going to talk about them as as quickly as I can
Speaker:I'm going to discuss them in relation to actually those three blockchains. I've already mentioned Bitcoin
Speaker:Ethereum and Solana I may throw in some others as well
Speaker:but I think these three actually give us a good idea of
Speaker:Kind of the trade-offs that are made and why is this even important? Well, I think you will find in the long run
Speaker:That it's very important
Speaker:And I'm talking about five to ten years the choices that blockchains make
Speaker:around these three
Speaker:Legs of the stool so to speak will determine in my opinion
Speaker:How well they perform in the future if a blockchains not scalable and it will fall on its face
Speaker:It will eventually if it becomes popular which would make the you know, the token price go up. It won't work
Speaker:If your blockchain doesn't have security it will be compromised if it's not decentralized
Speaker:Ultimately that may end up causing you a problem
Speaker:so we'll talk about each one of those in relation to some of these more popular blockchains and
Speaker:Give you I hope a framework so you can evaluate look. I'm not telling you that
Speaker:you shouldn't
Speaker:Invest that you shouldn't invest in a blockchain that doesn't
Speaker:Rank really well on these but it does give you a framework certainly for your long-term investments
Speaker:Which of course here at generational wealth with cryptocurrency is something we're always keeping in mind. I'm not in this for the day trading
Speaker:I'm not in this for the short term. I'm always looking five to ten years from now
Speaker:Is Bitcoin still gonna be around as a theory? I'm gonna be around is Solana gonna be around is
Speaker:Phantom that's a new token, right? Everybody's hot is Phantom gonna be around. Well, I don't know
Speaker:How does it do on these things and we're not going to talk about Phantom right now because I don't know the
Speaker:Specs on that in regards to these but just as an idea you can apply this same framework
Speaker:If you do your research if you need to on these things
Speaker:Let's talk about decentralization
Speaker:What does decentralization do? I'm going to talk about two things. I'm sure there's a number of others
Speaker:it does provide for sensors it makes a blockchain censorship resistant a
Speaker:Second thing it does it makes it resilient and I will give you a good example of this
Speaker:we saw this earlier this year when China stopped the
Speaker:Mining of Bitcoin when they banned Bitcoin mining earlier this year. What happened?
Speaker:Well, a lot of those miners left China Bitcoin didn't shut down
Speaker:It might have gotten a little more expensive
Speaker:The miners actually made more money because of that who were still online
Speaker:Things shuffled around the hash power went down a little bit, but it all settled out and
Speaker:Because it's decentralized because there was people everywhere things kept going
Speaker:Ethereum Ethereum is pretty decentralized and I'm just going to go in this same order from
Speaker:I guess maybe their birthdate if you want to put it that that way
Speaker:I'll try to be as fair as possible
Speaker:Ethereum Ethereum is also quite decentralized
Speaker:One of the reasons that Ethereum is so decentralized is that the cost to run a validator is pretty cheap
Speaker:There are a lot of validators for the ETH 2.0 mainnet, which will be coming online here
Speaker:Hopefully in the first quarter of next year
Speaker:You can run one of those really off a laptop it's not ideal, but you could do it
Speaker:I've run a on the test network. I've run a validator running
Speaker:I think it had eight gigs of ram four cpus. It was only using a couple of gigs of ram
Speaker:And and one cpu actually to run that and I was running the validator
Speaker:I was running the beacon chain, which gets the information off the current mainnet
Speaker:And that was all running quite comfortably on that little machine
Speaker:And then finally we'll talk about Solana Solana is the newest of these it's not very old at all
Speaker:Solana is also not very decentralized for a couple of reasons for one thing because it's not very
Speaker:Own. I was thinking about this a few minutes ago with bitcoin
Speaker:Do you realize like when Satoshi started mining bitcoin?
Speaker:There wasn't probably a whole lot of information available online about bitcoin
Speaker:If something would have happened to him in those early days or her we don't know as always
Speaker:But if something would have happened to
Speaker:them
Speaker:At that point bitcoin never would have happened
Speaker:Because it was decentralized. It was not decentralized. It was centralized. It was on that one node
Speaker:Think about that. That's kind of crazy. And now of course, there's thousands of nodes and
Speaker:All this and you know, it's completely decentralized
Speaker:So
Speaker:Some of these you'll hear this with bitcoin. Oh, we're decentralized and you're not well
Speaker:Sometimes that's simply because it's a younger project
Speaker:Now another reason it could be is because of the cost of the validator or the mining rig
Speaker:Now I would argue with bitcoin that it's become extremely difficult to run a mining rig because of the cost you have to have
Speaker:In order to be profitable, you have to run a very specialized rig that draws a lot of power
Speaker:and
Speaker:It has to have a very specialized ASIC unit in order to
Speaker:Basically do the computations fast enough to be profitable
Speaker:And so those are expensive rigs. I think these days they're running six eight thousand dollars a rig
Speaker:not
Speaker:Trivial when you consider that within four years that it probably will be almost worthless
Speaker:Now, yes, you're mining bitcoin and you're going to make money. I get all of that
Speaker:But i'm not i'm just not a big fan of kind of that high cost
Speaker:Tell somebody who's making ten fifteen dollars an hour. Oh, yeah, you can mine bitcoin. Can I?
Speaker:And by the way when it comes to ethereum, it's the
Speaker:Kind of the exact opposite the rig itself is cheap, but you have to stake eth 32
Speaker:and
Speaker:Eth as you probably know is around four thousand dollars forty two hundred something
Speaker:Like that per eth so that's a lot of eth. That's a very expensive part of that setup
Speaker:now
Speaker:Several years ago when the specs for the validators were developed
Speaker:Maybe it's been two years. It probably hasn't been but eth was a lot cheaper
Speaker:But i'm hoping at some point they make an adjustment to the spec for the validators
Speaker:But i'm hoping at some point they make an adjustment that you don't have to have 32 eth to run a node
Speaker:All right
Speaker:Solana on the other hand
Speaker:You have to have a very expensive rig to run
Speaker:And it's a new blockchain
Speaker:The specs on the solana machine are just incredible
Speaker:The minimum specs are like 128 gigs of ram
Speaker:128 gigs of ram and let me go ahead and pull it up real quick
Speaker:12 cores
Speaker:The disk space doesn't matter. It's fairly high but
Speaker:Disk is the cheapest part of this. So i'll just leave that out of the equation
Speaker:Now what they actually recommend
Speaker:Is 256 gigs of ram or more
Speaker:And 16 cores that is a super expensive machine. So that would actually probably in my opinion be well
Speaker:Now that would probably be more expensive than the bitcoin mining rig
Speaker:I don't know if that'd be a good investment personally
Speaker:Because of that high entry cost and because it's a new setup. There's not a whole lot of validator nodes
Speaker:So they're not as decentralized. That's just
Speaker:The way that it is. Let's talk about security
Speaker:Bitcoin is known for its security bitcoin has a long history of good security
Speaker:That is one of the reasons why you don't see upgrades to bitcoin very frequently because they don't want to make a lot of change
Speaker:They do not you know, there's this
Speaker:movement in
Speaker:In computer circles and system
Speaker:management circles
Speaker:You know move fast break often that kind of thing
Speaker:Break it fix it move on you know
Speaker:You know, that's not the case with bitcoin. They're like they want something that's super stable. That's super secure
Speaker:So we did I mentioned this on the monday podcast. We did just recently have the taproot upgrade over the weekend
Speaker:That was the first major upgrade to bitcoin in something like four years
Speaker:Segwit was the previous one
Speaker:Now you can view that in two ways. Wow, they're slow and boring
Speaker:Uh, they don't have smart contracts. They don't have this out of the other
Speaker:or you could view that as
Speaker:Wow, they move slower so that things are stable
Speaker:and secure
Speaker:And that's and that is true
Speaker:Ethereum on the other hand
Speaker:Even though they well they've been around for a while obviously and just being around
Speaker:that helps
Speaker:Shake out the bugs, right? But
Speaker:But
Speaker:They do make changes more frequently. We've got a major change upcoming first quarter eth two
Speaker:Where we move to validators instead of mining essentially
Speaker:So we're moving to a proof of state network instead of a proof of uh
Speaker:Work, you could certainly say that probably provides for a less secure system not because of the switch but because of the changing
Speaker:And ethereum is making changes fairly frequently
Speaker:They also seem to do a really good job of it. Have they ever made a mistake probably? Well, they have
Speaker:That being said it's still a system that works for them
Speaker:In fact, just recently there was a bug
Speaker:Cropped up one of the clients
Speaker:I think it was one of the clients had some
Speaker:a bug in the code
Speaker:And it was the main client if i'm not mistaken the one that's used by more
Speaker:validators
Speaker:Uh more setups than anybody else
Speaker:But they fixed it within like the hour
Speaker:so
Speaker:It didn't cause a real issue
Speaker:so
Speaker:in one of the
Speaker:Computer terms that gets thrown around a lot programming
Speaker:Agile agile programming they they did respond to it very quickly and and they were quite agile about it
Speaker:They fixed the problem and moved on
Speaker:Solano on the other hand, uh
Speaker:Uh, they were knocked offline for a good bit
Speaker:recently
Speaker:So back in september, uh solano was down for 17 hours
Speaker:Not what you want
Speaker:Now, why did that happen? I don't know anything about solano development. It could have been because frankly because there's such a new setup
Speaker:Um, I hope so and I hope that doesn't continue
Speaker:But it is something that you have to consider
Speaker:Because this type of these bugs, these are the kind of things that do cause security issues that ultimately
Speaker:can cause
Speaker:Um long-term effects. All right third part of this scalability
Speaker:Scalability
Speaker:so
Speaker:Here's an area where?
Speaker:bitcoin
Speaker:Uh, frankly doesn't do very well. It's got a very low
Speaker:Transaction per second count what they call a transaction per second tps
Speaker:meaning how many
Speaker:Transactions how many you know, hey i'm sending a bitcoin to bob. That's a transaction, right?
Speaker:How many of those can it handle the main net of bitcoin cannot handle very many of those?
Speaker:And this is a system that's supposed to scale to cover the globe
Speaker:That's a given
Speaker:I'm going to go ahead and go through the others and we'll circle back
Speaker:um ethereum
Speaker:Really doesn't do very many
Speaker:right now
Speaker:um and
Speaker:It is more than bitcoin
Speaker:But it's really not that much again for a system that's going to be used for global finance
Speaker:Solana solana on the other hand frankly because it's more centralized
Speaker:They do do a much higher
Speaker:tps
Speaker:It's a crazy high amount so they have the scalability
Speaker:Kind of out of the box that the other two systems don't have now. Let's circle back
Speaker:bitcoin
Speaker:Bitcoin has the lightning network the lightning network on the other hand does provide
Speaker:scalability
Speaker:So lightning i've talked about this before there's a separate podcast about it
Speaker:That's all I talked about but it's a peer-to-peer
Speaker:Network kind of ad hoc network that's being built to allow virtually instantaneous very low fee payments
Speaker:That actually also are quite anonymous
Speaker:So it's a privacy win. It's a fee win
Speaker:And it's a speed win. So
Speaker:That so they're moving that
Speaker:Basically, they're kind of moving that off of the main net. So this is a layer two protocol
Speaker:It's not a protocol. It's using the bitcoin protocol, but it's a layer two solution. I would say
Speaker:Just like some of the others that we talked about a few weeks ago
Speaker:So ethereum ethereum is doing several things to tackle the scalability issue for one thing
Speaker:Down the road, they will be doing what's called sharding that will help with the scalability issues somewhat
Speaker:But the other way the way that vitalik has kind of positioned things
Speaker:He feels like a lot of the scaling issues will be handled through these layer two solutions things like the zk
Speaker:roll-up
Speaker:Solutions that we were discussing
Speaker:recently
Speaker:where basically you kind of bundle up a whole bunch of transactions and then they get
Speaker:Stuffed into the main net so to speak so you're on what they would call a sidechain. You're over here doing something
Speaker:Along with a whole lot of other people and then that all kind of periodically feeds back into the main net
Speaker:that helps a lot that can help a lot and some of the
Speaker:transactional
Speaker:throughput and cost
Speaker:for these are
Speaker:Very high transactions are very low cost. So those are very promising looking solutions
Speaker:Once they become implemented. They're not there yet
Speaker:again
Speaker:Solana solana's got it going on with scalability. So that is an area where they're emphasizing where honestly they're at least
Speaker:De-emphasizing the decentralization part. I'm not going to speak to the security part. I don't know the details. I do know
Speaker:They did have an outage
Speaker:Um because of a bug
Speaker:That may never happen again
Speaker:I don't know
Speaker:But you do see right there as an example kind of of the trade-offs
Speaker:of the system
Speaker:both ethereum and
Speaker:bitcoin arguably they're going slower they are emphasizing
Speaker:as
Speaker:At this point the decentralization and security and they're working on the scalability now
Speaker:It remains to be seen if they can truly scale these systems
Speaker:I think they both will it may take several more years, maybe five more years, but that's okay
Speaker:You know people are always going on about ethereum's gas fees, right? They're extremely high
Speaker:because it's such a popular system and
Speaker:Because essentially of this throttle of the lower transaction per seconds on the main net
Speaker:As more and more stuff moves off chain
Speaker:to these side chains
Speaker:You will see that the gas fees will go lower
Speaker:The eth 2.0 features that are coming up over the next few years will also help with that
Speaker:So ultimately we will have a main net that performs much better that the gas fees are much lower
Speaker:But you will also have all of these side chains and these roll-ups that will
Speaker:that will greatly increase
Speaker:The efficiency and lower the cost so those are going to be some really exciting times where oh and by the way
Speaker:I think I mentioned this in the roll-up
Speaker:Podcast, but those roll-ups those side chains they inherit
Speaker:Or they can if they choose to most of them do they inherit the security of the main net
Speaker:So if you have a secure main net, which I would argue that both bitcoin and eth have proven to
Speaker:To be secure then you can build upon that and you can make it scalable now
Speaker:then they had the
Speaker:The trade-off right of decentralization if i'm over here on some little side net that doesn't have a huge number of nodes
Speaker:That's not very decentralized
Speaker:But as long as there's an escape route, so to speak back to the name main net. I believe that that's
Speaker:That's a reasonable trade-off and I think well, we'll see that remains to be seen. So in summary these three
Speaker:legs of the stool
Speaker:of a solid crypto platform
Speaker:They are truly fundamental to the success of these platforms and
Speaker:It is very helpful to understand
Speaker:The trade-offs and understand the biases that you may have in even looking at these systems
Speaker:I have a long relationship with both ethereum and bitcoin and I
Speaker:Until proven otherwise, I will believe frankly that they're the best that's out there doesn't mean that I don't buy other things
Speaker:But I have a bias if you want to call it that towards those but I think you can demonstrate how they are
Speaker:Decentralized how they are secure their track record
Speaker:Well, neither one of them are scalable. That's the part that they've chosen not to emphasize
Speaker:But I do know what both of them in fact are doing to improve that scalability. So it's projects like that
Speaker:that
Speaker:Are going to help
Speaker:Move us into the future, right? Clearly we can't throw everybody on the current blockchain
Speaker:because of the current ethereum blockchain because
Speaker:It would come to a standstill but as we bring more people on board as it builds out
Speaker:There will be more capacity
Speaker:Transactions will be higher
Speaker:Fees will be cheaper
Speaker:The same thing is going to happen with bitcoin
Speaker:I see this. I mean the the stuff that's going on with places like al-salvador is simply amazing
Speaker:How that lightning network is being used?
Speaker:And the implementation the amount of liquidity the amount of bitcoin that's moving into that lightning network. It's stunning
Speaker:You i've seen these charts. They look like a hockey stick. They you know, because for a long time
Speaker:For a long time the lightning network was very little used and at some point
Speaker:People just kind of woke up and it was around the same time that al-salvador
Speaker:That whole deal started happening
Speaker:and probably because of that, but all of a sudden
Speaker:That usage
Speaker:Just started increasing and increasing and I mean, it's just going exponential and the more nodes there are
Speaker:The more decentralized it is the more reliable it is
Speaker:And i'm sure that that system is going to continue to innovate so
Speaker:I would actually like to see something more similar to that
Speaker:On the ethereum network and I will keep saying that maybe at some point somebody will hear me
Speaker:I don't really know how that can be achieved. I have an idea of being able to do it through zk
Speaker:Roll-ups, I don't know if that's actually feasible or not
Speaker:I would love to actually talk to somebody who knew a lot about those
Speaker:That maybe I don't know
Speaker:We we need a lightning network essentially for
Speaker:For ethereum in my opinion. I think it could be a valuable part of that ecosystem
Speaker:We don't need it, but I think it'd be valuable. So anyways, that's it
Speaker:I really don't have any news this week because we just did an episode a couple days ago. I will say this
Speaker:Yesterday the kind of things kind of tanked. We've gone down 10 15 percent
Speaker:Over the last couple of days
Speaker:The end is not nigh
Speaker:The end is not here
Speaker:Everything is fine
Speaker:This is not the end of the bull run
Speaker:We're not there yet. At least I certainly don't think so
Speaker:You do see if you've not been in crypto very long
Speaker:These markets are very volatile 10 15 20 percent drops nothing. We had a 30 drop earlier this year
Speaker:And it was not the end of the bull run. We've gone on since then to higher highs. So by definition
Speaker:It was not the end of the bull run
Speaker:I think the next six weeks and we may go sideways or even down a little bit here for a few more days
Speaker:But the next six weeks are going to be really exciting
Speaker:I think we're going to see some kind of crazy things just like we saw in 2017
Speaker:At the end of the last bull run
Speaker:So anyways, I hope this helps
Speaker:I really want to thank you guys for watching
Speaker:Anyways, I hope this helps. I really want you to take this as a framework for evaluating
Speaker:What you're going to hold long term?
Speaker:Because the ones that don't pull this off. Well, here's here's the punch line
Speaker:The ones that don't pull this off this compromise this trade-off between these three branches
Speaker:Is they will not be around in the long term and I would hate to see you have long-term investments in some token
Speaker:that
Speaker:Didn't make it. I've got more than one of those that at the end of the day
Speaker:When the rally was over
Speaker:The price fell
Speaker:And they didn't come back after that
Speaker:Okay, so I hope you guys find this helpful
Speaker:I will be talking to y'all next Wednesday in one more week
Speaker:It'll be the day before Thanksgiving
Speaker:Here in the united states
Speaker:Two days before yeah, no the day before thanksgiving
Speaker:Thanksgiving does take place on a thursday
Speaker:and so
Speaker:We'll listen to some crypto and then hopefully get a chance to eat some turkey
