> NFTs could enable people to transfer digital assets between platforms without needing the platforms to talk to one another. I could buy an NFT of a 3D model of some Yeezy sneakers, and then bring that NFT to Fortnite for my avatar to wear there, and to the Metaverse to show off there, and to a sneakers forum to verify my ownership in the community there as well. That could be quite useful. 3D cosmetic assets for games and stuff is a massive market, and using NFTs would enable people to transfer goods between those markets. It'd only really work if the asset itself is stored in some sort of distributed architecture though (IPFS for example.)

This ignores the actual implementation. You still need the platforms to talk to one another in the design stage at least (the most difficult one) in order to be able to create an asset that can actually be used in different applications. If right now you cannot upload a 3D model to Fortnite straight away, why do you think it would be easy to do with NFTs?
A bit of learning about Racket structures
Until you end up in jail... sadly.

That is my point. If your country is "sufficiently bad" bitcoin will not (and cannot) help you in the long run.
What exactly is it? I understand there is something about code puzzles but how does it work? How does the leaderboard work - presumably there is some sort of scoring involved?
I personally had a hope that we’ll build some new decentralized things, some real new web - more sustainable, reliable, less regulated, less censored.

My heartbeat was increasing every time I was finding some project promising to build this new network.

But every time, after lines of poetic, pure, brave, and romantic description of their mission, there was a line about their new token and why you should buy it.

With the time I’ve got the immunity to such promises and prejudice - they all are just scam projects.
Maybe you just failed to explain to that person what the roadmap of going from coin to blockchain powered book of law looks like, because it's quite the road.
I’ve never been convinced by claims of using blockchains for probably supply chains. While it’s true a blockchain can’t provide a shared ledger that both parties can trust has not been tampered with after the fact, it doesn’t say anything about the world outside the blockchain, so does not remove the trust problem.
No,there is a flap that mixes outside air with hot air. The fan is always on, depending on how the flap is set you get more hot air mixed in with the outside. The heat side is always hot when the engine is warm, even on the hotest summer days.
My real bank won't send a wire transfer on a weekend with settlement time measured in seconds, so no, it's not like a bank.
Actually, the trend is to put the RAM inside the main chip itself so as to avoid those pesky latency and area-costly PCB traces. The performance improvements this allows are hard to resist and some manufacturers are already falling in (e.g. Apple). And I guess the side effect of making upgrades impossible is nice, too.
I think it's because no real tangible thing has come out of the cryptoverse (apart from rare exceptions like ransomware gangs cashing out tumbled coins and buying lambos and rolexes). Everything in the crypto sphere is just 1s and 0s or in the ether. Everyday Joe reads up about Bitcoin and the first thing they want is a solid physical coin they can hang on their wall. On the other hand: people use BTC to acquire illegal drugs via the darknet, so there is a case to be made for BTC being exchanged for tangible goods, albeit a tarnished one, since those drugs are banned in most countries. BTC got a bad name early on, and has yet to shake that off.

I'm not sure if I'm looking forward to banks and governments launching their own digital currency. It will be interesting to see how that plays out. If it means it's highly traceable so it can't be used for illegal things, then so be it. That's where we're heading now.
It doesn't seem very fast or simple or possibly even cheap if I consider only fiat as money.

That is I have money in one country and I want person to receive it in their own currency in other one.
If we look at the current moment there’s not much in the way of new, interesting things going on with cryptocoins tech wise or use case wise.

It’s top of mind because some people are getting rich quickly in it. What’s interesting about that?

Should we also still be talking about people making tendies on GME?
Video of robotic plug:

Worlds largest electric ferry connecting to a automatic robotic charger station

Here it says "5 minutes" for charging (15 minutes trip):

https://press.siemens.com/global/en/feature/pioneer-position...

"At nearly 98 meters long and 16 meters wide, the Elektra can transport up to 90 cars per trip. The ferry purchased by FinFerries will now be traveling this route every 15 minutes. The batteries will be charged in roughly five minutes while cars move off and onto the ferry. The two lithium-ion batteries each have a capacity of 530 kWh. "
Is there a source for that? Last time I checked there weren't reliable reports even on total energy usage, much less energy sources.
> It's already that way in the US, the percentage of paid off home owners is ~29%.

That 29% is a huge chunk of people; to put things in perspective US presidents win elections with a lower percentage of support from the population.

> I don't know why some people consider themselves "owners" of assets the bank actually owns, but it's normal in the USA.

Because they actually have equity in that asset, and that equity might be the majority? For example, they bought the house for $500k, then ten years later they owe $350k but the realisable value of the house is $800k. If the house is turned into cash, they own more of the cash than the bank does.

Also, because there is a clear path to ownership[1]? You aren't at the whim of the landlord - upgrade (or not) your property whichever way you feel is best with very little interference from the actual "owner" (i.e. the bank). If you have complete say in how an asset is used, and when it will be disposed off, and who may use it, that sure looks like ownership to me.

My residence, for example, will, at the current trajectory, be completely paid off in 24 months or less. My monthly costs drop dramatically at that point, which can be the major goal when "buying" property.
I disagree. There is a lot of interesting things to discuss. But all of them start from the premise "blockchain works as a distributed ledger". People in the camp you are in are not that interested in those discussions, because you disagree with the premise.

These interesting things are about how to do privacy, build second layers, make other smart functionality, etc. In general there are actual cryptographic innovations coming out of these systems. Zcash was truly positive to research into Zero Knowledge Proofs.

At the same time, discussions often get muddied by a few vocal people who are trying to hype up their investments. I imagine some of these people are just hyping, and others have bought into the believe, and cannot handle the cognitive dissonance of 'maybe there is something wrong with this'.
In Europe, you cannot send wire transfers to Japan on weekends in a couple seconds. So the problem is not solved in Europe. Posting "there's no technical reason why every bank cant coordinate to provide a non-terrible experience eventually in a hundred years" is not helpful. We have working international settlements for any origin to any destination for any amount of money in seconds today.
> I think that I see in my network of people that the more technically apt they are, the less they believe in it

This is because they just see the blockchain as an inefficient database, rather than really understanding the problems Bitcoin solves and why Satoshi made the choices they did. There are important trade-offs between efficiency, redundancy, decentralisation, and robustness in an adversarial environment.

The other aspect is that they just look at Bitcoin through a technological lens and judge it inferior to other networking & data storage technologies. They don't have a deep grasp of the concept of money and what properties makes for a sound form of money. Vijay Boyapati (ex-Google engineer) does a pretty good job explaining it from that perspective [1].

It's a shame that so many, otherwise smart, people are sleeping on such a revolutionary change in the world. The idea of Bitcoin has been thought about and predicted for many years by people held in high-regard among HN readers, such as Buckminster Fuller [2], Henry Ford [3], and Friedrich Hayek [4], and they'll still dismiss it out of hand.

Such a massive lost opportunity for great skills, knowledge, and talent to be applied to what I think is one of the most important innovations of our civilisation.

This was a weekend project I wrote when my team's regular ice-breaking question website began to recycle questions.

Use it on your Monday Daily to shake off the weekend. Or use it every day to build trust in your remote-first team. Or hit it on mobile to start a conversation with a stranger.

It's open-source, never-track, open to submissions, and with over 2000 questions, seeing the same question twice will be a rare event.

Cryptocurrencies are a problem. From the environmental disaster they cause (and social problems caused by higher electricity prices due to increased demand), to tax evasion, illegal porn, or the fact that an important share of an entire generation became addicted to gambling under the guise of "technology".

The real world has problems, and crypto currencies have made some of them possible. Far from making the world any better and bringing the current financial and political system down (lol), they made the world worse. As these problems become more evident and widespread, cryptocurrencies become a political problem. The world needs to deal with the problems they cause and the political solutions will differ. That's why people argues.
And really banks or large organisations don't need crypto for money transfers. They are already doing it in vey well established systems, with well defined contracts and so on. Blockchain adds nothing, when piece of paper or electronic record saying "hey we owe you this much" or "this loan is debt obligation is now yours"...

Sure it oversimplified (most opinions that are somewhat transferable are).

I agree with the hope for a better stewardship, but as all people end up moving cryptocurrencies in and out of the "old" financial system (creditcards, swift etc). I fail to see how crypto would help me..

I for one cannot pay for my rent, food, heat, water, power, internet with crypto, can you?

» It’s a minefield buying a car and ensuring you get all the right features (a key, a spare wheel, physical buttons for controls)

Hi, have you found any small car (I am thinking Toyota Corolla/Camry Honda Civic/Accord sedans) that comes with a full size spare? I drive a 2007 Toyota Camry that I bought in 2019 for about USD 5k. I know Jeep Wrangler and bigger vehicles sometimes have a full size spare but I'm not particularly fond of driving.

People on YouTube joke and say Toyota Camry is the perfect car for people who don't like driving but I can't think of a better description that fits me.
Proof of stake is already happening. It's on Ethereum (though they haven't switched over to the beacon chain from proof-of-work yet), and it's on many others.

If you look at the top 100 cryptocurrencies by market capitalization, maybe bitcoin and 1 are 2 others are proof of stake. There are a bunch of 'tokens' cryptocurrencies which exist on top of another blockchain, but the remainder of the layer 1 blockchains and all of the layer 2s that use a consensus mechanism are using proof of stake now.

Arguing against crypto because of proof of work is like arguing that computers won't see mass adoption because vacuum tubes make them impractical to fit inside of a typical home.
Quite interesting, but I would like to also see other benchmarks as the author said that the speed is constrained by the DB, ORM and other stack choices.

My main criticism comes from the fact that Bitcoin (and other crypto-coins) had a good several years to find a purpose, to this day, I am not aware of a single use-case where they are used to solve a real world problem.

If I had to sum up how I feel about Bitcoin (/ crypto / block chain..) -
magic buzz word for the non-tech-savvy ,draw for gamblers & ego driven individuals, theme of quasi-fake money-grab startups..

I think one of the things that ruined Bitcoin is it becoming this "asset" instead of a tool to get something done, maybe proving something about a truly "free" market, maybe there's a lesson here.

It would be great if that was true but I would still feel kind cheesy putting it on my CV. That might just be my own biases speaking though.

You're confusing concepts and blockchain fundamentals. "Uncloneability" is the double-spending problem solved by proof-of-work/hashcash scheme. The 51% attack is not the problem, it's just a requirement for a PoW based blockchain to work. Just like how you have 1/3 honest node requirements in traditional BFT distributed database designs.
Looks good! I've been thinking about making a writable version of https://github.com/uktrade/stream-unzip, but looks like you beat me to it!

(Full disclosure: I'm the main developer of stream-unzip)
I think it's especially divisive because the only way to further it is with increasingly ingenious, sophisticated argument. This doesn't come down to simple concepts: it's hypotheticals, projections, a call to imagine what COULD be, and a great deal of pressure to buy into one or another predicted outcome.

This becomes like a game. It's a logic puzzle. How do you construct an unanswerable argument that produces your desired result? It's much less interesting to go 'well, wait and see, things will doubtless become more obvious as this progresses'.

Under some circumstances, the ONLY way to establish a currency that actively supplants and destroys all fiat currency, displacing governments and replacing their control with only market pressures enacted through completely liquid and untrammeled flow of capital… is to ram it through with such desperate haste that it's too big to fail by the time it's recognized as a threat by those controlling governments. To topple governments and replace all their control with anarchy governed by only market pressures, the ungovernable replacement currency has to be so huge that the pressure of committed capital ITSELF is more powerful than any government.

This is a big, dramatic 'ask'. Whether it's wrecking the world and ruining the environment is a whole separate question. Arguably the bigger question is, 'SHOULD there be a currency that allows the pressure of purely capital to overthrow this or any government?' Especially since by design it is NOT a hierarchical power structure, but distributed and impossible for anyone to control… does that produce desirable results?

Mind you, if you get that and THEN find out it's possible for the system to be controlled anyway, you're pretty thoroughly hosed… you have to trust very much that the system put in place to overthrow all governments, truly represents a distributed and ungovernable system. Otherwise, you just overthrew all governments in order to hand all power over to somebody that you don't know who it is.
Pyconverse – Conversational transcript text analysis library
In the same vein as what Linus is trying to do now at LTT, it would be useful if there was a "programming journalism" lab which builds "test benches" to create canonical benchmarks and verify the claims made on tech blogs (etc.).

Eg., highly standardised docker builds, on highly standardised hardware, running popular tasks using popular libraries for each "programming tech" (eg., website, stat modelling, event system, ...).
The Chinese Remainder Theorem has a fascinating consequence, which is to enable the Residue Number System:

https://en.wikipedia.org/wiki/Residue_number_system

For example, since 2 and 3 are coprime, if you store the residues of any number N modulo 2 and 3 separately, you can do additions, subtractions and multiplication modulo 6 by doing the same operations on the two residues (independently of each other).

With this system it is possible to arithmetic on huge numbers in massively parallel fashion. The drawbacks are that division is hard (except when you know that the division is exact), overflow detection / comparison are hard, and converting from the residue number system to N is expensive.

You're wrong about "lacking initiative and the detailed procedures" - that's exactly what blockchains were created for: As a response to opaque and unreliable systems. This is the solution to a systematic problem in governance.

Blockchains simply add verifiability of claims. Yes, you could create a central system which flags "bad actions" or something, but it'd be difficult to prove someone scammed you without the cooperation of the central authority. Breaking the rules digitally shouldn't be possible in a properly designed system, which is what some blockchains can provide.

Currently if someone says "no I didn't scam you", the truth of their statement is ambiguous without cooperative investigation. On a blockchain it's inherently unambiguous and the information is immediately available for all parties involved to know how to proceed.

Obviously this has more applications than scammers/cheaters, which is why blockchain tech is so heavily experimented with and being integrated in so many other areas of tech.
You could also randomly select with a bias to meet any particular requirement of gender, ethnic background, poverty etc. but possibly that's not currently legal in California.
I think that is disingenuous. Because there remain interesting things to discus and consider in the world of 'crypto', even if you acknowledge there are issues and its not perfect yet.

There certainly are some loud 'shills' out there. But there are also actual interesting technical developments. It seems to me that between the shills and the people shouting down who they perceive to be shills, the interesting discussion gets drowned out.
Last I looked the so-called proof-of-stake was more a system where somebody put up a stake to be witnesses (in lack of a better word).

When I say proof of stake, I mean it in the way of "proof of possession"
It is a comparison of two averages, not of a single temperature to an average. A changing average suggests a change in the underlying factors at play, because while a single observation may not ever match the average as you say, a system in equilibrium should not see the average changing. This is why it is called anomalous: the mean is changing continuously.

It’s a crude metric but in the framework of the analysis (pre-industrial vs post-industrial) it is an appropriate comparison.
The issue of payment processors cutting off perfectly legal and valid organizations, individuals, or whole classes of activity is a separate issue.

I was thinking more from a desirability and sales perspective. From what I've heard, the problems with the Fremont factory were not replicated in the Chinese production line, so hopefully they will also not plague the German factory or other future factories. It's understandable in a new car company. It's only a problem if they don't address the issues. As for now, every single electric vehicle made by anyone is in such demand that they are sold far in advance. It will be several years until demand can be met, if not longer. That's about as good a problem in manufacturing as one is able to have.

Chrysler has no EV models. Chevy has the Bolt. Ford will be offering compelling vehicles but not in any numbers for a good while. As far as other legacy automakers, it looks like Hyundai and Volkswagen group will be eating everyone's lunch.
