I've since taken to running a non-public Monero node, which will become public when I can ensure my network security as it's being run from my home.
In saying that, there is a lot of concern around the new Carrot changes. To preface, I don't understand it enough to have an opinion either way, but a good chunk of the vocal user base seems to be worried that making “optional” view keys show both incoming and outgoing transactions will force the hand of the remaining exchanges, and be a condition of adoption of new exchanges to support Monero.
I haven't really seen a dumbed down explanation from the core Monero team as to exactly what the change looks like, and what the theoretical implications could be. It would be nice if Monero had more accessible PR for non-technical users to encourage adoption and squash FUD when it arises or at least acknowledge it from a top level in a blog post or something so that the already hyper-paranoid user base doesn't unnecessarily drive a mass anti-Monero campaign.
Crypto wasnt so much straight up privacy, but like high information / low revelation. The idea was to create an economic system where you the individual could have relative anonymity while being able to go online and audit the bank in detail. Not a criticism of you enjoying monero I just think this got lost somewhere.
I think Ethereum is probably going to strike the closest balance eventually, but it depends on a lot of factors.
Are cryptocurrencies supposed to be a potential replacement for real life cash? This was my understanding of the motivation behind Bitcoin, at least.
If so, why does it make sense that people can "generate" cash by proving some amount of work done? This of course cannot be done with normal cash.
Is the main functionality of these cryptocurrencies supposed to be "people can send currency to each other", or "people generate currency -- a number -- and sell this currency for real life money"?
For a state or central bank the answer is obvious: The state or bank itself prints it.
For a private actor the technical means is perhaps less obvious, but the actor behind the currency obviously gets to decide.
For a decentralized open source project, it is less clear. You could do it so every node in the system gets a piece of every newly printed unit of currency, but if it is free to run a node everyone could just run a billion nodes and take all the currency for themselves.
Bitcoin solved the problem with Proof of Work, which is elegant because both the double spend problem and the minting problem is solved together. Every node has to prove it has run a unit of useless computation and inflation is spread evenly across worker nodes. This led to a split between nodes and miners with the use of specialized hardware, but the basic premise still holds.
Crypocurrencies in general are very different. Ethereum, the second most popular, was created by a private actor and the that actor decided to print 72 M for themselves and promptly sold 80+% before the release of the software which gave rise to the term ICO which was very trendy for several years. After the initial release inflation continued according to the miner model.
They are supposed to be a medium of exchange. “Real life cash” is one of many forms of money; even for any particularly currency, like dollars, a very small fraction of use is “real life cash”. But, yes, in the most extreme visions, cryptocurrencies replace other currencies for all uses. More moderate visions, however, exist. So, as always when you use “supposed”, the answer is undefined without qualifying it as to by whom it is supposed.
> If so, why does it make sense that people can "generate" cash by proving some amount of work done?
Because there needs to be some mechanism to provide the currency supply, and also some incentive for people to provide the infrastructure on which the currency system relies. For fiat money systems the first is typical policy making in a central bank, and the second is government action to control competition in the banking space and to support banks, reinforcing the profitability of banks. Mining serves both of those functions in a cryptocurrency system (both reinforcing the profitability of transaction network participants and providing the mechanism by which currency supply is managed.)
> Is the main functionality of these cryptocurrencies supposed to be "people can send currency to each other", or "people generate currency -- a number -- and sell this currency for real life money"?
Participants in a currency system selling it for other currencies (FOREX) is a feature of every currency system in a world with more than one currency. Again, the degree to which each of those is “supposed” to be the main function depends on exactly whose supposition you are looking at it.
And in some cases, which mutually-inconsistent argument the same entities are making. For example, when the thing's a dollar-replacing currency at the start of the interview, and can't-miss investment commodity by the end of it.
The big flaw of Bitcoin, to my mind, is that it is an inherently deflationary currency. Deflation is one of those things that seems great on the surface: prices go down, not up, but when that happens it ends up creating an economic incentive to avoid spending since why buy something today if it will be cheaper tomorrow, and this ends up causing economic activity to slow down or stop entirely. A small amount of inflation, on the other hand creates an incentive to either spend money or invest it in something that will provide a better than inflation return, whether that’s putting it in a high-yield savings vehicle or making capital or financial investments. With deflation, you can just leave your funds in cash (where they will not provoke any economic growth) and get a return.
Fractional reserve banking. Basically, bankers start getting very anxious when they see the masses of people depositing mountains of cash into them. They look at the cash hoard they have suddenly amassed and think, we can't just leave this pile of cash here doing nothing, we have to efficiently allocate all of this capital. So they lend it out to people who need cash, charge interest and pay account holders their yields.
Deposit $100. Bank loans out $90, and $10 sits in its reserves. Your account still says $100, even though the bank is now leveraged against loans to third parties. Guy who took the $90 loan pays some bills, and that $90 ends up deposited right back into the same bank. So it keeps $9 and loans out $81. There is now $100 + $90 + $81 in circulation, but only that $100 is real money, the rest are all made up. They only become real when loans are repaid. So, the $81 gets spent, deposited back into the bank, and so on, and so forth, expanding the money supply like a fractal until the amounts become too infinitesimal to track. Thus $1,000 easily becomes $100,000 literally overnight. Government could run its presses 24/7 and it would not be able to outcompete the banks when it comes to inflating the money supply.
Banks are the financial call stacks of society. Better hope there aren't any exceptions (defaults), or the whole thing unwinds and comes crashing down.
It's like a society wide financial version of ISP oversubscription. The assumption is nobody is going to stress test the system by saturating the link 24/7. Everything breaks the second the invariants are violated. Banks similarly assume that not everybody will need all of their dollars immediately, which lets them "efficiently allocate" all of those dollars. Entire government systems exist just to bail out the banks where this assumption fails to be load bearing.

Yep. Not a single change to the moral calculus here. Banks want to be as leveraged as possible. They want to risk it all: their own assets, and other people's money. And they want that risk to be subsidized by society itself. And society allows it because it's addicted to cheap credit. Loans are so thoroughly wired into people's finances at this point that weaning them off it is actually dangerous, not just politically inconvenient. So we'll keep building up and unwinding financial call stacks, and the godlike oligarchs observing and programming the system will keep profiting from the peaks and valleys while everybody else just keeps getting rekt. Nothing new here.
The limits to banking are when the last creditworthy person prepared to pay the current price of money walks through the door.
What do you buy bank shares with? Bank deposits.
It can't. It isn't. And it never has been.
What banks do is provide liquidity against your collateral. You sell them a charge over your house (for example), and they give you a credit for it. That credit can then be passed on to other people.
Banks are in the business of discounting. They don't take anything in and give it out to other people. [0]

The assumption behind the “deflation is bad” argument is that spending itself is the goal. But spending is not automatically good. Productive spending and productive investment are good. Wasteful consumption, speculation, and forced risk-taking are not.
If money holds its value, people become more selective. They still buy food, housing, tools, entertainment, experiences, and things they genuinely want. Humans have needs, preferences, status impulses, advertising pressure, and finite lives. Demand does not disappear just because money is sound. What disappears is some of the artificial urgency to spend before your cash loses value.
The more important point is investment. In an inflationary system, holding money is punished, so everyone is pushed out onto the risk curve. You are not only investing because an opportunity is great; you are investing because the currency is being diluted and you need to escape it. That distorts the real cost of capital and makes mediocre investments look better than they are in nominal terms.
With harder money, investment has to beat the return of simply holding the money. That is a healthy hurdle rate. Capital should have to prove that it creates real value. If an investment only makes sense because the denominator is being debased, or because everyone is forced into assets to avoid inflation, then maybe that investment was not as productive as it looked.
This also matters for inequality. Inflation does not hit everyone equally. People with capital can protect themselves by owning stocks, real estate, ETFs, businesses, and other assets. They can diversify, borrow against assets, and ride asset inflation. Poorer people are more likely to hold wages and cash, so they are the ones whose purchasing power gets diluted first. Then they are told to “just invest,” but they are competing against people who already have capital, better access, better tax treatment, and more room to take risk.
So inflationary money quietly forces the poor to compete with the rich on the rich person’s playing field: asset ownership. A broad ETF may look like a safe wealth-preservation tool for someone with money, but for someone living paycheck to paycheck, the need to buy risk assets just to avoid being diluted is itself a problem.
A deflationary or hard-money system would probably reduce some marginal consumption and speculative investing. But that is not obviously bad. It may mean fewer bad investments, less artificial asset inflation, and more pressure for capital to flow only into things that genuinely outperform money itself. It would also be much more sustainable, not just economically but materially: if money no longer pressures everyone to consume and invest constantly just to outrun debasement, there is less incentive to waste real-world resources on unnecessary production, overconsumption, and short-lived goods.
The fear is that nobody would spend. But people do not stop buying things just because they expect their money to hold value. They stop buying things that are not worth giving up good money for. That sounds like discipline, not economic failure.
Bitcoin might be approaching it.
Spending shouldn't be the goal, but exchange of goods and services should be. Representation of real value should be a goal. If you can receive real goods and services as a consequence of holding numbers on a spreadsheet, instead of a consequence of providing real goods and services yourself, the economy has a problem. Maybe a system with zero inflation or very slight deflation can be stable, but the extreme deflation seen in Bitcoin is destabilising.
“Holding money and earning interest from holding it” is a category error. Holding Bitcoin pays zero yield. No coupon, no dividend, no debtor, no tax stream, and no mechanism by which poor people pay holders a percentage. If someone earns interest, they are not merely holding money; they are lending it, which means they are taking risk and providing capital.
The “numbers on a spreadsheet” objection is also just an objection to money itself. Money exists so someone can produce value today, save the claim, and exchange it later for real goods and services. That is not a bug. That is saving.
A non-inflationary currency is actually a better representation of real value, because the unit is not constantly being diluted. Inflationary money lets nominal wealth rise even when no real value was created. Hard money makes the test harsher: did you actually create value, or did the measuring stick just get worse?
And no, people would not “just sit on Bitcoin.” People still eat, rent, travel, build, compete, seek status, start companies, buy homes, and take risks to outperform others. The only thing that changes is the hurdle rate: an investment has to be better than simply holding money. That is not economic failure. That is discipline.
The fair criticism of Bitcoin is volatility and unequal distribution, not this imaginary mechanism where holders magically receive interest from the poor by owning spreadsheet entries. That mechanism does not exist.
EDIT: The rich/poor angle is almost backwards. In an inflationary system, holding money is a guaranteed loss, so ordinary people are forced to become amateur investors just to avoid being debased. Rich people are already positioned for that: they own assets, businesses, real estate, equities, and can borrow cheaply against them.
In a non-inflationary or hard-money system, simply holding money is not a guaranteed losing strategy. You keep your share unless you voluntarily take risk to increase it. That is a very different game. The rich can still get richer, but they have to outperform by allocating capital well, not merely by being closest to the asset-inflation machine.
Same with wages. Under inflation, your employer can cut your real salary without saying anything: they just give you a raise below inflation, or no raise at all. You have to fight constantly just to stay even.
Under hard money, that hidden pay cut is much harder. If prices are falling or money is appreciating, keeping the same nominal salary can mean your real wage rises. To reduce your real compensation, the employer has to make the cut explicit or offset it with benefits. That is a completely different power dynamic.
So no, inflation is not obviously pro-poor. Very often it is a quiet tax on people least able to escape cash and wages.
I'd accept "leaky currency" as a substitute for inflation. The important thing about inflation is that you have to keep running just to stay in one place - not that the numbers keep going up. Stable prices are nice, I agree on that.
Bitcoin's volatility is caused by its deflationary nature. Monero is inflationary, and much less volatile.
In an inflationary system, normal people are forced to keep earning money. "Becoming amateur investors" is your way to say "keep generating real value". If you want to surpass Elon Musk you have to invest, but that's nothing to do with the inflationary currency. That's because Elon Musk uses deflationary currencies like land and Ponzi currencies like Tesla stock. He just sits on them, and he will get out of the Ponzi ones before the top because he controls them. As they say, bad money drives out good. But you cannot build a stable economy on hyper-volatile gambling.
No. Monero's tail emission rate was specifically chosen to be less than the rate of global gold production. Do you claim the price of gold is intended to decrease?
A continuous emission like Monero's doesn't equate to inflation/devaluation. It allows its userbase to expand organically, without artificial scarcity pumping its price.
Lettuce rotting is not an argument for money rotting. Perishable goods decay, machines depreciate, buildings need maintenance, and inventories have storage costs. Prices can reflect all of that. The measuring unit does not also need to decay.
Money is not supposed to preserve lettuce. It is supposed to preserve a claim on value across time. If I produce value today and save the proceeds, I should not be forced to lose purchasing power just because the unit of account was designed to leak.
Also, “forced to keep earning money” and “forced to become an investor” are not the same thing. In every system, people have to keep producing if they want to keep consuming. The difference is that under inflation, even after producing and saving, your savings are diluted unless you buy risk assets. That does not necessarily mean “generating real value.” Often it just means bidding up existing assets.
Bitcoin’s volatility is not simply “caused by deflation.” It is caused by uncertain demand, adoption cycles, liquidity, leverage, regulation, speculation, and the fact that it is still monetizing. A fixed supply makes price more sensitive to demand shocks, sure, but that is not the same as saying deflation mechanically causes volatility. Monero’s tail emission is also tiny, under 1% and declining over time, so it is hardly a normal inflationary currency.
And the Elon Musk example basically proves the opposite point. Rich people already escape inflation by holding scarce assets: land, equity, businesses, real estate. Poor people are the ones stuck holding wages and cash. A harder money system does not eliminate inequality, but it at least stops making cash itself a guaranteed melting ice cube.
Wrong, in a 'deflationary' system the more a rich person holds money in proportion to the total money the less interest they are likely to extract/get. If they hold all the money interest they will be effectively get/extract will be zero.
Money doesn't have any value, none, zero.
Unless you like watching a piece of paper with Washington or the Queen of England or landmarks in Europe on it, so at least it could hold a value of "I can look at it/burn it".
It's value is none, zero.
That's true both for fiat and crypto.
They are absolutely, inherently, worthless.
The value is given by third parties wanting that money. That's the only reason it has a value.
And your country making some currency (generally its own) the legal tender ensures that that specific currency is used to trade in that country thus reinforcing this "value".
To me the entire idiocy of the crypto cultists is not understanding that money is worthless.
Even the richest people on the planet have very little of it. Their wealth is tied to owning assets be it estate, shares, art, cars, whole companies, funds, etc.
Money is worthless, you're at the mercy of other people wanting it tomorrow or in one year or in 10, and at the mercy of what the market will decide it is worth.
This is how money works. If you use a medium of exchange and unit of account for goods and services then that medium must increase at the same rate as the increase in goods and services otherwise you get second and third order effects such as inflation, contraction, rising unemployment, etc., directly impacting its ability to act as a unit of account.
In Bitcoin you don't generate cash, you earn block rewards for acting as a consensus broker which otherwise would require a central banking settlement layer. This activity, tied directly to the transaction layer, acts to maintain the equilibrium between increases in goods and services and expansion of the money supply.
Wall Street got ahold of it and now Bitcoin is primarily acting as a Store of Value for the purpose of speculative investments. Driven primarily by the fear of missing out and market manipulation since Bitcoin is heavily centralized.
Block rewards have no connection to transaction volume or economic activity, the protocol is designed such that bitcoin supply increases at a predictable (and diminishing) rate. Bitcoin is deflationary by design, which is one of the major issues that stopped it from becoming anything other than a speculative store of value.
Well, for now. Obviously it can't reduce forever, and it will eventually slam back up to infinity (bitcoin will collapse) when no normal person feels like it's worth getting any because so much of it is already owned by wealthy people. Until that happens we're surfing the Ponzi wave. Inflationary designs are way more stable.
Insomuch as beanie babies are a store of value. Speculative assets only have value as long as there are more greater fools to buy in. When you've exhausted the supply of greater fools, there is no more reason to buy the speculative asset because its price won't go up, so it will fall to its intrinsic value, which is the worth of a normal stuffie for a beanie baby (roughly $5) or the worth of a number stored on other people's disks for a Bitcoin (roughly $0), which is the value ultimately stored. Wall Street is only involved in Bitcoin to facilitate trade between fools because we have collectively done a poor job of regulating this madness, allowing so many fools to eventually lose their money to a distributed Ponzi scheme and sanctioned countries.
Can't say I like crypto, but I think better arguments can be made against it.
The artificial scarcity and lack of actual use of bitcoin really isn’t the same.
The second part is that despite these disclaimers, I don't think gold has, in modern history, or will in our lifetimes, reach a price reflecting just the use/intrinsic value. The reasons being twofold: the storage of value IS a use itself; and importantly, which applies to Bitcoin and others, there are always people that will be willing to buy the dip, which is how the requested new generation of "fools" comes from.
And for this, having a private ledger is cheaper and more efficient for moving stored value in a way that is recoverable by law and doesn't support sanctioned regimes.
Think of it this way: If you pay with physical cash, there are people somewhere who do the work of digging ore out of the ground, smelting it, shaping it into coins, cutting and printing paper and so on. All these people do that, because they get paid in the same currency that they themselves have minted.
It turns out that nobody has yet found a way to create a digital decentralized currency that that works without incorporating a similar concept of incentivizing the creation of currency.
Most cryptocurrencies, if we go only by their number, are designed to make their creators rich and moderately succeed at that. This is your ERC20s, pump dot fun, et cetera.
If we only consider ones that have any serious chance of being usable as actual currencies, these days they're usually designed to run arbitrary money-like programs known as "smart contracts", of which traditional money is just one.
Money can't be sent until it's generated, that's the same whether you're talking bitcoin or dollars. There's always a rule for who gets the new money when it's created, and somehow the rule always ends up being "rich people get the new money". Dollars go to politicians and big bankers, bitcoins go to big compute farms, ethers go to big bankers, monero goes to big compute farms. The aforementioned get-rich-quick currencies go to their creators, if course.
The BTC implementation clearly has failed in this role, but not Bitcoin protocol (look at BCH, for instance)
Transaction fees used to be free, but miners started to require at least 1 sat/b, to prevent "spamming" the mempool, so... no.
This was the original stated purpose, yes. But this works poorly in practice. Hypothesized frictionless tooling that would make it easy to make purchases with crypto has not emerged.
Nowadays it's held more like a speculative asset with value that comes from scarcity and demand, much like gold (though gold has some industrial application which Bitcoin does not).
Because you need an incentive for 'miners' to participate in transaction processing.
Main functionality is transactions which are not controlled by any single entity (like the government).
Most of it is speculation unfortunately, which gives it a bad name, drowning out real usecases.
Why mine at all?
If you want to scale up to Mastercard levels.
Mining is what generates the coins. And you need mining because otherwise you need some other issuing organism. Without decentralized mining you get a central issuer, and that's untrustworthy and possible to shut down.
PoW miners are rewarded for correctly validating transactions, with newly minted coins.
The whole proof of work thing is that you proved that you validated a transaction by expending energy, and the network pays you for that security service.
Miners then need to sell those coins on the open market in order to pay for their capex/opex, which creates the market.
The open question is that if you have a fixed supply of coins that eventually runs out, what will carry the miners?
It'll be increased fees or the network will switch to another solution.
I would add a different way to make sense of it.
Proof of work allows for what Keynes called "Bancor". BTC is succesful because unlike fiat central banks, the money supply isn't dictated by interest rates (and thus loans) but by the effort of participants. The price of BTC is almost irrelevant, BTC itself is a paradigm shift.
Regarding the fixed supply, it's only fixed because participants agree to the consensus algorithm that fixes it. Many cryptocurrencies have different tokenomics, such as ETH's rules under PoS. BTC miners could vote onchain for a hard fork to change the 21M cap - or another solution.
Correct on the rest, but I just want to say that I was intentionally avoiding discussing specific tokens or the politics due to HN's stance on crypto.
For a currency, that means you still need issuance, and you still need security.
Miners, glossing over a lot of theory, provide security in exchange for receiving issuance. They can be seen like the decentral bank of the crypto world.
Cryptocurrencies allow market participants to communicate value to each other without having to trust other market participants or an institution. Mining verifies transactions and commits them to the public record, earning the miner a fee for their work.
I think the better word would be alternative, rather than replacement.
Crypto currencies have way too many flaws to be really useful as currencies.
Not just usability, technology, fees, etc, but the very deflationary nature of most of them makes them unsuitable as a currency because the incentive is hoarding, not spending.
But...you can still use them as a mean of transferring money. So they are absolutely an alternative.
In an effort to make Bitcoin a reasonable medium of exchange, various businesses arose to act as intermediaries/market makers. But this violates the trust-free model – and many of those intermediaries have proven to be outright scams. It turns out that trusting an intermediary to handle your cryptographically untraceable asset is not a wise thing to do.
So that leaves Bitcoin in a similar category as gold. You're either a paranoid type for whom the high cost of holding and transacting the asset is a price you're willing to pay for an asset that could survive a global meltdown. OR you extend trust to various intermediaries (gold ETFs, bitcoin ETFs for example) and treat it as just another tradable financial asset.
Bitcoin is undeniably the cleverest way anyone ever became a billionaire. Nakamoto's sole contribution was posting an anonymous 9 page whitepaper to the internet and voila, today he (or she, or it) is worth $80+ billion.
The current fees are less than 0.40$. It may be too high for a starbuck coffee, but that's way lower than the fees charged by a credit card provider if you are purchasing something over 50$. On a 2%+0.10$ structure, you only need to transfer around 15$ before your credit card fee is higher than the current average BTC tx fee.
Normal cash is just printed out from thin air by those who have the power. In that sense (some) cryptocurrencies are better because at least the process is open.
Yes, it can be! Just open a bank.
> why does it make sense that people can "generate" cash by proving some amount of work done? This of course cannot be done with normal cash.
People do generate money when they work, in a sense, because money doesn't have value. Money represents value. To really understand that you need to think about what money is and why it was invented in the first place.
Before the invention of money there was only direct exchange; I do/give something for/to you and you do/give something for/to me in return. But what if you want what I have but I don't want what you have? Or what if we want something from each other but are too far apart to make the exchange directly? Well, we find a third participant who can act as a kind of transfer agent. They could, for instance, have something I want that you don't want and also want something from you. They trade with you first so now you have something from them that you don't want that you can then trade to me for the thing you want, and everyone is happy. This extends to arbitrarily many, dozens or hundreds even, of intermediate steps.
Now it should be easy to recognize two things:
1) Everyone needing to store a bunch of stuff they don't actually want just so they can pass it on to the next person can become a huge burden for everyone. And how do you store labor anyway? You can't. You can only store goods.
2) Organizing dozens of intermediate links is an extremely difficult problem to solve just so you can get what I have.
The first one can be solved by exchanging IOU vouchers instead. The holder of the voucher becomes entitled to the thing that hasn't yet been given or done. Storing those vouchers is trivially easy compared to storing the things. And you can just as easily store vouchers for work that hasn't been done yet as you can for goods that haven't been given yet.
The second one can be solved by saying what if people put their vouchers into a central voucher bank instead of passing all their vouchers around to each other directly, and then the central voucher bank organizes all the intermediate steps for people without people needing to figure out who has the vouchers they need to complete the chain.
And then once you're there, why even use specific IOUs at all? Why not have all the vouchers be generic but you get different amounts of them instead of different kinds that you can then use freely for anything? And that's obviously what money is.
And from there a new thing should become obvious: The money itself doesn't have any intrinsic value. The labor/good behind it does. Money is just a way of representing the value of something you did/produced in a form that can be easily traded for other things. It's the medium of exchange, not the product. And when there are fewer vouchers in the system relative to what's being produced, each voucher becomes worth more (deflation), and vice versa (inflation). And then the government literally prints and destroys vouchers as needed to try to keep a balance. That is a thing that happens. And so what if there can be prolonged time delays between you doing your work and you receiving your vouchers under some systems? Time delays are not inherent, just practical for bookkeeping. And when long time delays are not practical for bookkeeping they become shorter.
> Are cryptocurrencies supposed to be a potential replacement for real life cash? This was my understanding of the motivation behind Bitcoin, at least.
Only as an unrealistic pretense in the current climate. The reality is that a currency needs to be both moderately inflationary and also very stable to be useful as a medium of exchange of goods/services. You never want it to be a better financial decision to hold onto currency forever instead of using it, and you also never want people to randomly wake up destitute. And regardless of whether bitcoin is technically inflationary in the near term, it is not practically inflationary, and it's definitely not stable.
This is ahistoric. Widespread barter is only really takes place in post-currency societies. Pre-currency societies mostly engaged in reputation or "gift" economies. When I have a surplus, I share with peers, with the understanding that they have done and will do the same in the future. It can be tempting to map that social obligation onto currency debt, but reputation doesn't really behave the same way as currency does. It's not linearly combined (giving someone with no bread a loaf of bread is going to provide you much greater than half as much standing with that person than giving them 2 loaves), its transaction costs are much, much lower (you probably wouldn't pay the village idiot, but if you enjoy listening to his tall tales, you probably think fondly enough of him to help him out in a pinch, or share some extra berries you found, or you might value the fact that your neighbor gave a loaf of bread to the guy with none from the earlier example, but it would be weird to pay him for that indirect, incidentally service), and it's barely portable: maybe your kid might benefit somewhat from your prestige in the community, but unless he lives up to it it doesn't matter if you saved the village by single-handily slaying the lion that was picking off children and livestock. Likewise you can't just hop over to the next village and expect people to help you any more than basic hospitality rules demand.
Monero is similar to Bitcoin Cash, a useful replacement for cash in most cases.
One thing I didn't understand though is Light mode:
> Fast mode is for mining. Light mode is for verification. The reference README says
The post only describes Fast mode, right?
Presumably verification is done by miners who already have the memory set up so Fast mode would be faster for them.
Verification is still relatively fast because you don't have to try gazillions of nonces so who is Light mode necessary and how does it work?
The post described both modes. The only difference is that Fast mode processes the cache to generate the full 2.1GB dataset, so subsequent programs can just reference it as needed. Light mode uses only the 256MB cache and generates the required dataset values individually, on each access. That saves RAM but costs more CPU time.
Personally, I'm going to look into RetoSwap, but I appreciate Kraken sticking it out keeping it listed. I might not have gotten any Monero if not for Kraken.
You could just use Trocador directly and skip the "hackerish" aesthetic and save 2% on fees.

Most miners use AMD Ryzens. Couldn't tell you the actual breakdown of CPU types in use. Apple's M series CPUs are quite efficient at it too. Bitmain now sells a "Monero RandomX Mining ASIC" which is just a bunch of RISC-V cores, seemingly based on Sophon SG2042 SOCs. There's nothing special or more cost-effective about their product.
You can mine on old smartphones quite easily. I use a bunch of old Android TVboxes myself. Their hashrates are nothing to crow about, but their hashes/watt are still competitive with faster CPUs.
There is a RandomX V2 that will be deployed soon. Its main improvement is even cheaper verification cost.
It might lead to scenarios where a miner may optimise block generation itself, I guess?
I was more curious about the possibility of generating optimised branchless variants and then running them in parallel on multiple ASICs to ensure you cover every branch and submit all the results and hope you’re fast? Would that be more inefficient than relying on branch prediction and CPUs?
And this also makes it hard to generate favorable programs.

But solving the problem of how to transfer value trustlessly and anonymously, instantly anywhere in the world is one of the biggest breakthroughs since the Internet.
Amazing how in a few short years kids started growing up with Bitcoin and don't understand how it work or why it exists :(
But it's still mostly about the speculation, it seems.
Bitso processes 10% of US-MX remittances. 12% of people in Argentina use stablecoins. The shift is happening in real time.
Free speech is for all the stuff you personally detest and personally choose to avoid. In a free country you hold your nose and allow others to engage in it.
If money is speech, then having a kind of money that doesn't pass through policy gates is an essential component of a free society.
Happy to continue discussing if you'd like to reply to what I wrote.
Point is, it's a currency you can use right now independently from the increasingly unstable-looking US dollar.
You could also use euros, yuan, rupees, or Australian dollars but it's really hard to get an account in those currencies if you don't live in those countries. Crypto is much easier to get access to.
We are 15y in and there is still no trace of a meaningful use case outside of the ones I mentioned. I don’t think it’s a failure of bitcoin itself (it’s a neat proof of concept), I see it more as a complete delusion of people pushing cryptocurrencies
Also wall street never considered it seriously until a few years ago.
And who's gonna admit that bitcoin is a ponzi scheme when all of their savings are in it? you can't, it would devalue your own money, so you're trapped, you can only further invest in it.
1. Illegality 2. Speculation (i.e., gambling)
So yes, +1. :-(
I can use my compute and energy how I like, whether that’s for AI or crypto or a Minecraft server. You don’t have a right to call one “wasteful” and one not
I can have a computer on an endless loop without any idling, consuming as much CPU time as it can, I do not know any other classification of this action than wastefulness. crypto mining is useful of course, the end goal of mining is to get crypto, of course, there is no further goal beyond that.
Objectively, Minecraft is a game, an objective of many games is to waste time, therefore this cannot be used as a measurement, but enjoyment is. as a game it fulfills its role. wastefulness could be classified in comparison to other solutions/clones, like minetest. If minetest fulfills exactly the same goals with less action as minecraft, then minecraft is in comparison wasteful.
Another measurement is mining solutions can we achieve the action of mining with less compute? can we not mine at all? does not mining achieve the same goal? if it does, then mining is objectively wasteful.
The objective of crypto is replacing fiat currency, it does not do this, therefore it is wasteful. Of course, this is only true until it does replace it, which is why we must compare, would this cryptocoin scale to the entire world? does it require more work for it to do so? if so then it is wasteful.
Just as an example, aave lost 295 million last month due to a hack in another protocol, and nothing was posted here.
A good example was the truck manifestation in Canada a few years ago, they went after all the donors for what was a legitimate protest. Anyone using bank transfers or any crypto that wasn't Monero was persecuted.
Those who used Monero had their privacy assured and zero issues.
Courts deemed as unlawful this government persecution to whoever donated to the protest using transparent cryptocurrency: https://usethebitcoin.com/news/canadian-court-rules-against-...
The point is that only those who used monero were safe from unlawful government persecution.
He received plenty of USD in cash delivered in hands by the US government through the three-letter-agencies. These kind of things always happened, it is unfair and incorrect to blame crypto currencies whereas the overwhelming majority of "special operations" continue to be paid today in plain paper money.
I was interested in Monero because it actually was what people thought Bitcoin was.
The reason why cryptocurrencies exist is precisely to detach money from governments, reason why Monero is persecuted by every single western government whereas that coin you mention is endorsed by them. There is quite a world that needs and uses Monero every day.
Still a global blockchain though with the associated throughput limits. You can't buy cereal with monero because you do that too often.
Wouldn't risk sending large transactions where everything is visible to others when compared to LTC or any other non-private virtual coins.

it's binary, thus 2^30

> Data rate: 10 Million bits/sec
RAM modules have to have power-of-two size for technical reasons. These reasons do not apply to telecom, magnetic storage, etc. Has nothing to do with "binary".
It is hilarious.

The history of people trying to design GPU or ASIC-resistant proof-of-work functions is long and mostly unsuccessful. I haven't looked into RandomX; it's possible they've succeeded here (or possible that with the alt-coin market mining profitability tanking after Ethereum moved to proof-of-stake, it just wasn't worth it).
I'll add that there was such a large influx of miners at the outset, that (statistically) it seems any crippling of the original algorithm was fairly futile - the edge was both short-lived and minimally impactful. We're over a decade later, and nobody mining in the first month (even with that unfair advantage) was able to gain any meaningful percentage of Monero's emission.
I'll add that RandomX has proven that it is indeed possible to create a GPU and ASIC-resistant PoW algorithm. I'd encourage you to dig in further - the closest to an "ASIC" is a multi-CPU miner (Bitmain X9) with a bunch of RISC-V CPUs in it.
But be careful about "proven" in that last sentence - the absence of a solution isn't exactly proof, it's more of a proof that _either_ it is possible to create an ASIC-resistant algo _or_ it has not been worthwhile to ASIC-ify it given the economics of mining XMR and the research & NRE required to do so. I haven't the foggiest which of those two it is, mind you, just that there are a few remaining valid explanations.
In this case the claim was ASIC-resistant PoW is possible, and the proof has been the historical behavior of miners after years of RandomX. Nobody said it would be eternally or entirely resistant to optimizations...
> It's a proof that something is possible to show one example.
Agreed.
> the proof has been the historical behavior of miners after years of RandomX.
> Nobody said it would be eternally or entirely resistant to optimizations...
These are contradictory statements. If historical behavior was a proof, then it would be eternally and entirely resistant.
In reality, no one has been able to build any device for RandomX that isn't actually a CPU. The closest thing to a "mining ASIC" is just a bunch of RISC-V cores.
I think what the evolving Monero team has done, for many years since inception, is wonderful to the point of inspiring. The thoughtful approaches it has consistently taken over many upgrades reflect a much greater level of competence, responsible goals, clever design, and a clearer consistent vision than all but a few alternative systems.
(Including better choices than Bitcoin, which seems to have completely elevated code stability over any problem resolution (user privacy/safety, transaction scalability, environmental damage, etc.). Stability over all non-critical features including ergonomics (i.e. transaction times) is a very strong, but legitimate choice. But not stability over basic failures/limitations relative to current function.)
Disclaimer/scope: I do not own Monero or any other cryptocurrency, but have in the past. My comments are purely about technology, with no financial/investment dimension.
The random programs change too quickly to just implement them directly on an FPGA. Reprogramming the entire chip like that takes too much time.
----
To anybody else that is syncing a fresh monero blockchain copy (i.e. installing the official client), I recommend using the custom node flag ` --db-sync-mode safe ` — which is slower but corruption-avoiding — before node's initial bootup. Without safemode, any halt of the client will [most likely] corrupt the local blockchain (losing days of DL/verification).
Also, if you use an SSD for storing any blockchain (as recommended by monero team... but not by me), know that its lifespan will be greatly reduced from the constant IO/access. Personally, I recommend safemode (see above) on a 7200RPM spinner (HDDs effectively don't wear during IO/access).
----
What are your thoughts on running xmrig vs. the default getmonero.org client? Would you in general agree that monero remains ASIC-resistant?
Would be curious if the marginal savings from a heat pump would allow you to buy more monero than you mine with this energy.
[†] It's an older model, without reversing valve (circa early-2000s).
[ƒ] ...and refrigerator (thanks /u/twic)

>if the marginal savings from a heat pump would allow you to buy more monero than you mine with this energy.
In a colder climate, DEFINITELY (to a point: see /u/nerdsniper's great point, below).
----
I replaced a 300W "toe heater" with this rig; by directing heat to only wear its needed (i.e. muh'toes), I can heat the entire house less (whether resistive or heatpump).
Actually, I suspect heating-by-monero-mining is more likely to economically beat heat pumps only in the very coldest climates. Heat pump efficiency goes down when the temperature delta between inside and outside is very large. Below 0F or so, it's quite difficult to find heat pumps that will work sufficiently well, and generally they transition to resistive heating.
Caveat: I'm only talking about marginal advantage, ignoring the capital costs of the Xeon servers or the heat pump itself.
As far as placement of the machine: underneath your computer desk is ideal, as this directed heating allows you to keep the house's thermostat a few degrees cooler.
----
If anybody were to ask me "what would you BUY to mine monero@home," I would definitely tell them to [instead] buy a heatpump-heater, -watertank, -&c (presuming they don't have each, already).
Particularly on its initial sync, Monero's daemon is flakeyAF.
If you (e.g.) don't allow `sync in background` (why is this not the default behavior?!), the official Monero client is notorious for locking up on wakeup. Once you kill the process, your local blockchain is [most likely] unusable.
Another reason to use safe-sync is (e.g.) if your system (Linux or whatnot) decides to update/restart during the several days it takes to sync-initially.
----
Just out of curiosity, why do you abuse an SSD so (safe-mode, or not)?
For SSD-diehards, I'd recomment getting a very large size because this'll last longer, presuming the drive self-levels.
Totally false. LMDB is perfectly crash-proof in that scenario and killing the process never damages the DB. The only thing that's not guaranteed is turning off syncs, in the face of an OS crash/power outage.
If you don't sync, you're not abusing the SSD. If you run on Windows, the OS is too unstable to use without safe sync mode though.
This is a well-documented failstate. Usually results in "unable to connect to 127.0.0.1:18081" errorlog, which is most-commonly due to a corrupt database/blockchain (from hardstop/kill).
In order of crashout likelihood: Windows >> MacOS > Linux
>If you don't sync, you're not abusing the SSD.
If you don't sync then you're not (cannot be) a fullnode / network verifyer / ringsigner.
----
>LMDB is perfectly crash-proof
It is my understanding that once your initial-sync has completed, the default monero node behavior is to then automatically enter the --safe flag (I described above).
This may be old behavior... I go way back (years beyond a decade). My only modern use in xmrworld is as a personal foot-heating ATM.
I was talking about database sync, not blockchain sync. You don't need to use safe sync mode if you don't have to worry about machine crashes. And just killing the process will never corrupt the blockchain DB.
> This may be old behavior... I go way back
On this particular point, I go way back further than you.
Definitely know who you are (LMDB programmer &c), and your contributions to world & crypto tech – thanks (few people can claim, like yourself, that their code exists on BILLIONS of machine). I've ALSO been in cryptospace longer than Monero's existance... you are hands down a better programmer than myself (I'm a bluecollar electrician), with much more name recognition.
----
BUT: You aren't listening to my "layperson user behavior report" about a common and known behavior of the default getmonero.org node. I would love to help you&team better stabilize/configure the default client behavior/options...
Please don't let hubris stand in our way of spreading the gospel of crypto. If you want me to sign some custome statement with a BTC hash (dating back to the earlytimes) just send me a postcard (I no longer use email). But you shouldn't need that to listen.
>just killing the process will never corrupt the blockchain DB
I would love to show you how easy this is to reproduce, even on fresh installs of Ubuntu and/or MacOS on otherwise-stable hardware (never tried Windows... easier?).
----
Loved your 2019 talk on "is XMR still ASIC-proof" – is it still, in 2026, in your opinion? Your line about ~"our goal is to make a hash algorythm so dynamic that if you designed an ASIC processor for it... it'd essentially just be a CPU"~ – classic quoteable.
> I would love to show you how easy this is to reproduce, even on fresh installs of Ubuntu and/or MacOS on otherwise-stable hardware (never tried Windows... easier?).
If it's so easy to reproduce, you should be able to screen record a session with two terminal windows:
1 with monerod running and syncing the blockchain
2 send a `kill -9` to the monerod
1b restart monerod
And then we should see the error message you're referring to.
Will also provide the perplexity.ai chatlogs that I used to both find other similar crashouts and resolve my issues. Again, I am not a programmer but have been accepting crypto (with client discount) since 2012.
Thanks again for your contributions to this community.
----
As you're capable, do you happen to know why the default configuration doesn't sync in background – this is just wild... anybody installing XMR-adjacent software isn't going to expect this behavior.
...the re-sync (after stopping due to timeout) is always where my issue appears.
The LMDB backend (I know it's you're baby) could possibly be having a freakout when Linux comes back online?! (from e.g. sleep) – I genuinely don't know – but am happy do demonstrate my frustrations (that I've had literally & reproducably on both Linus and MacOS distros (across YEARS).
Thanks for the approachability.
Yep. Nothing about computing architecture has changed.
----
>once your initial-sync has completed, the default monero node behavior is to then automatically enter the --safe flag
Is this still true, too?
I have no reason to lie, I'm not selling anything. Bitmain is selling mining hardware, take a look at their claims. They've had 7 years to try to crack it.
Because it was written by Bram Cohen, I'd be interested in reading two or three sentences about how it collapsed.
Because it's a blockchain-based cryptocurrency, feel free to stop writing after three or four sentences.
Thank you for sharing!
(To be clear: We were just optimizing mining; in the process of looking for ways to mine it faster, I found some security bugs and fixed them. We weren't exploiting the bugs, that crosses a line for me.)
Why even mention that era? Your fascinating by that time was shorter than its post Random X lifecycle
The brilliant part of Bitcoin is that it uses very widely known crypto primitives - verification is the same as getting the right seed (you just happen to be told what the right seed is, rather than having to pay for it to be discovered).
