NFT's are a weird thing, it is half scammy (practicality) and half useful (ownership, non-fungibility of the token itself). I am reading up on the NFT standards (ERC721 is the simplest one) [1] and this is the core contract API:

contract ERC721 {
// ERC20 compatible functions
function name() constant returns (string name);
function symbol() constant returns (string symbol);
function totalSupply() constant returns (uint256 totalSupply);
function balanceOf(address _owner) constant returns (uint balance);
// Functions that define ownership
function ownerOf(uint256 _tokenId) constant returns (address owner);
function approve(address _to, uint256 _tokenId);
function takeOwnership(uint256 _tokenId);
function transfer(address _to, uint256 _tokenId);
function tokenOfOwnerByIndex(address _owner, uint256 _index) constant returns (uint tokenId);
// Token metadata
function tokenMetadata(uint256 _tokenId) constant returns (string infoUrl);
// Events
event Transfer(address indexed _from, address indexed _to, uint256 _tokenId);
event Approval(address indexed _owner, address indexed _approved, uint256 _tokenId);
}

It's not hard to understand. This ERC721 NFT token can verify is its owner (ownerOf()), and the actual item of interest (tokenMetaData()). Item of interest is secured either on the blockchain itself or offline using URL reference in the metadata.

All good. But that's all she wrote. Banksy can list his digital artwork on the internet and many people can bid on it. That is actually valuable if you think about it in isolation. The problem is on the auction side, with decentralized bidding - you have no idea if this artwork was pumped up by fake buyers. There is no Sotheby's or Christie's auction house to mediate this.

URL metadata is also weird - now you're passing on the value of the token to whoever owns the Domain Name and the servers responding to the GET request. If the artist decides to sell or forgets to renew the domain name, your NFT is useless unless the data was backed up somewhere. Even then, the next buyer of the NFT would want to access the URL and get their goodies instead of getting it from anywhere else since that's not on the tokenMetadata.

Back home in Slovakia we have our own set or tales/stories, composed together by Pavol Dobsinsky in 19th century from various folk sources. They are pretty brutal too, murders even within families, treachery in all forms, even cannibalism. Killing bad guys pleading for mercy.

They don't go to gory details, no point in that, but they don't avoid it either. Times were different - half of kids before age 5 died, everybody could easily die from flu, inflamed appendix or a tooth problem. There were public execution held in bigger villages and towns. Wars, skirmishes and murderous bandits ravaged countries.

Killing of domestic animals was (and in many places still is) a fiesta for whole family, including the smallest, ie butchering of a pig or sheep. Not done somewhere hidden, but in plain sight of everybody.

I don't think we get how exposed to brutality in many forms the kids were back then.

Also, I have modern print of original texts and see no issue with reading them, many parents still read them to their kids. I was exposed to them as a kid and didn't find them shocking.
Ownership and chain of title pre-dates many of the centralized governments that even exist today. For example, who was the monarch of Italy when Da Vinci painted the Mona Lisa? How many times has the government changed hands since it was painted? How many times has the painting changed hands? How do you determine the Mona Lisa's authenticity?

Many heirlooms go back centuries and pass down through generations even as those generations move jurisdictions.

The Nyan cat gif NFT was composed by the original meme creator. That gives it value.

What does it mean for a baseball to be autographed with Babe Ruth's signature? If it's authentic, it means a great deal. There's no court of law that is going to validate if a Babe Ruth baseball is authentic or not and whether that fact gives it value or not. That is going to be up to the market of appraisers.

The crypto part gives you a perfect chain of custody. I'm giving you a digital item, that is provably rare and verifiably linked to the original creator of the artwork.
If you just randomly press keys (keyboard face roll) it will still type out the code. Sometimes I feel like this is how other people actually write their code.

When I encounter some of my own past work when I thought I was being "clever", sometimes that's how I feel about my own past work. It's a always a reminder to me that I should avoid trying to be too clever.

Sorry, plopping JavaScript on top of blockchain is not something I would call visionary. Smart contracts were there long before eth. Ethereum is a huge pre-mine scam with lots of promises and very little delivery. It’s got nice PR, but it’s really the PHP of cryptocurrencies. But of course almost everything else except bitcoin is much worse.

Turing completeness is literally a bug in such system. It’s an anti-feature. You shouldn’t want it. It’s a model of evaluation where halting problem exists.

But hey, it’s a nice buzzword for script kiddies. Great foundation for financial system, right? :)
NFT only exists inside a specific smart contract operated by someone within some specific rules implemented in the contract. If the smart contract is seriously built, in order to "control" the NFT cloned as an "exact" copy of it, the copier has to control an exact "copy" of the smart contract where the NFT resides.
The only way I see to achieve this is to know the private key of the owner of the original smartcontract or of someone who has the power to operate it.
It follows that if they control the "exact" copy of the smart contract in an "cloned" blockchain (forked or crafted) they also control the smart contract in the original one.
At that point the problem wouldn't be the "copies" but the "original" NFT.
If they instead craft a copy without crafting the original smart contract, that would be easily spotted.
Your nyan cat besides being unique, has also an "origin", the smart contract, and that can be easily being verified.
The same applies if someone creates "another" nyan cat inside the same blockchain. That would reside on some other smart contract and easily spotted as a copy.
Nvm. Seems like time has nothing to do with it, just if it gets signed by the creator. Not sure how that part gets verified though.
But that only has to occur once with the blockchain. Once it is encoded, and recognized to be authentic, the record will remain. Transfers will be recorded perfectly in the ledger. With physical items, the provenance has to be determined independently every single exchange.
Death traps because rest of the vehicles are way heavier and more dangerous (also to pedestrians).

If all cars were like that it would be fine.
When you have built in support for threads in a language, it definitely makes sense that it would be easier to use than operating system mechanisms. For a lot of the non-embedded code that I end up writing, though, there's usually an inherent benefit to using processes over threads. It usually comes down to the benefits of having separate memory spaces. You can safely use code that was never written to be thread-safe, saving time otherwise spent refactoring gnarly old code. Also, it makes it a lot easier to mix and match different languages. For python in particular, it avoids having to battle for the global interpreter lock.

I think what's nice about rust is that, because it makes it difficult to write thread-unsafe code, it's naturally easier to add threading at some point in the future without too much pain. As a result, more applications can benefit from having access to multiple CPU cores. I don't think that's quite the same thing as pure performance per watt, though. That really comes down to how the code was written, and how well the compiler can optimize it. Rust may have some advantages there over C, since it constrains what you can do so much that the compiler has a smaller state space to optimize over. Someone who knows what they're doing in C, though, could likely write very efficient code that effectively uses parallelism, and may gain an edge over rust simply by cleverly leveraging the relative lack of training wheels. For high performance compute, rust vs. C may be a wash. For consumer facing applications, though, the more programs that can use multiple cores to run faster (even if less efficiently), the better.
If I may piggyback on your question: isn’t it only the hash of the digital asset that is unique and that you own as a NFT (e.g. an ERC-721 token wrapping the hash)? So if I change a single pixel or compress the picture with a slightly different setting, I get a new hash and can upload it as a different NFT. At that point you need to compare the NFTs and decide whose claim of true progeny to trust with things like original owner address and timestamps. Or am I missing something?
Why would a developer implement this? What incentives do they have, other than being able to say they did? Digital cards being locked to an account was the greatest achievement for TCGs in the past decade. Non-tradability is a feature.

This applies to every single form of game-based NFT. What incentive does a Game Developer have in implementing their items on the blockchain? So I can trade my WoW Health Potions for FFXIV Health Potions? In a kind world, when I'm tired of WoW I could safely transfer my wealth from WoW to FFXIV, but does Blizzard want that? Better to ensure lock-in. Further there will never be the case where a game like WoW would recognize an item from FFXIV as canonical and equal value. I wouldn't be able to buy a FFXIV health potion and use it in WoW.

The only games that will implement NFT items will do it as a gimmick. TCG, or normal game, or anything.

I have yet to see an actual compelling use case that solves a problem that game developers have. Remember, solving a problem a player has doesn't mean the incentives for game developers are aligned.
if hypothetically one could ban cars from cities and only allow such low powered transport, it would be quite an efficient safe and clean form of transport
Google did this in 2002(?). I remember billboards in downtown Seattle with no text or logo other than [math problem].com.
Turing completeness is an anti feature in financial system like bitcoin. And pretty much zero contracts currently deployed to ethereum require Turing completeness. It’s just a buzzword to sell you this gigantic pre-mine scam.
I just built an app for this, if you have a LiDAR iOS device. https://keke.dev/blog/2021/03/10/Stray-Scanner.html

Well, the initial owner buys (or receives as a gift) the painting directly from Picasso. That's an easy one!

It gets more complicated later: experts assess the credibility of the painting by examining the ownership history, if available, the signature on the painting, the quality of the work, chemical properties of the pigments and canvas, etc. They sometimes get it wrong, though (cf. Beltracchi!). It's more a probability that a work is genuine, rather than a 100% certainty.
> By contrast, the entity that purchased the NFT for the Beeple JPG does not have any rights whatsoever over the JPG or its intellectual property.

This varies by NFT. Like software, different NFTs have different license agreements. Some grant exclusive copyright ownership to the holder of the NFT. The industry as a whole lacks standardization in this respect. But the main NFT marketplaces are working on this.

If they would be used for city speeds only, the risks aren't much bigger compared to scooters, in contrary.

But I have 0 doubt that being priced so aggressively, US and Europe would slap such a huge tariff to protect local markets, they would be very uncompetitive.
Better than scooters they are supposed to replace.
It is interesting to see sentiment change over the years on hacker news.

First EVs were too expensive.
Then they were too slow/couldn't tow.
Then the range was too small.

Now people are griping that they can't "refuel" in 5 mins.

I guess we will see what the next excuse becomes for people to continue polluting and why EVs "aren't ready" for their hypothetical/once-a-year/niche needs.

Sigh.
The US auto market requires a lot of specific safety features even compared to other developed countries.

There are plenty of new cars from leading global auto manufacturers that aren’t legal for sale in the US.

For ETC I don't think there is much debate. The original Ethereum paper and protocol still describes ETC whereas if you want to implement an ETH node that verifies the blockchain you need to write special code to introduce the block containing the collection of transactions reverting the hack.
Totally agree. It looks like there's an alternate version available via OpenType, which is much more traditional.
As percentage of total revenue, MongoDB service revenue is about half compared to what Oracle generates. My guess is customer churn is much higher for MongoDB.
Australian here - was listening to a local doctor who has a radio program. He travelled to the US for something and remarked on the number of people he saw squinting - apparently this is treated here by the appropriate glasses when young (for free) but not so over there.
Something Important for Someone Important
NFTs for art are a bet on new titling systems. Duplicating an NFT to different chains, or just different NFT frameworks/systems on the same chain, is akin to filing a Chinese copyright for something already filed in the US. Which one is valid or "real" depends on which system you subscribe to.

The existence of the tokens on a chain means nothing without the social acceptance of their meaning.

It wouldn't be suitable for US highways. It would make sense if regulators would allow another class of vehicle for city cars.
Thanks for the memories.

I think one of the bad things about getting older that people don't seem to discuss is the increase in death of both those you know or those you know of.
The price likely wouldn’t be very competitive if the manufacturer adds all of the design features required to sell that vehicle in the US.
It’s an odd hack, though.

Adding a bit of randomness results in a more interesting exploration of Borge’s Library of Babel, but it seems weird to assign meaning to the word choice?
Isn't this a question of bandwidth? The less data sent over the net, whilst maintaining a decent level of quality, the better for the end user.

The question of the available higher sampling rates are most often used at the recording stage, to capture the highest quality possible. And 'highest possible quality' will of course depends on your microphone.
In what way is it extra steps, as opposed to the same number of steps?
A bus is something computers and peripherals comunicate on. Think PCI, PCIexpress, USB

My mom who lives in Milan has had something similar for more than ten years and it works great. Cost a bit more than $4000 at the time, but not much more, and it's saved a lot of money in gas and taxes.
> for the Beeple JPG

is not an industry problem. Another big player is NBA Top Shot, which also is not selling IP rights.

In theory, something like an NFT could be useful. But this isn't about standards at this point. The NBA isn't retaining IP because there's no standards, they're doing it because they're not going to give away their valuable IP when suckers will pay to say they paid for a receipt.
What are the brand and model names?
Sure, original MOND no, but original MOND is not an actual theory of gravity. People try to make actual theories of modified gravity that replicate MOND's predictions, but you can't actually just use MOND as a theory of gravity. These MOND-like theories of modified gravity then include extra fields.

This was actually a somewhat significant reason I shared this article. (^.^)
I purchased all NFTs ever.

Huh. Guess it doesn't sell you that right. Merely the right to prove it. How often are people proving they own the NFTs? Never?
Vice city had the best cast.
By copying the NFT onto another blockchain you have created a different, new NFT. The original NFT owner still owns it, and can transfer it to a new owner
I would love a modern version of them were evil is a bit better distributed and not always a woman, the savior is not always a young handsome prince and the reward a wedding. As a white guy re-reading them with my daughters I find them boring and stereotypical. There are many modern versions but they are also often based on the Disney edition.

From a German perspective book cancelling (burning) is an incredible dangerous road. We had that in our history once and its lead to nothing good.

Create better ones and advocate them. Disney did that, just, in a bit too American style (oh-my-god-my-kid-cannot-hear-this-word-or-see-a-boob). That is the road.
NFTs, that are based on the ERC-721 standard, are not really transferrable to another blockchain. This is because NFTs have internal state variables that are managed in the Ethereum VM and you cannot trust the execution environment of external blockchains. This makes them stickier to the native chain they are minted on than even ERC-20 tokens.

Of course, in an open source world, there's nothing stopping anyone from forking your work at any time. How many Bitcoin forks have been spawned off? You can copy the BTC source code but you can't make a community follow you. Likewise, if someone were to mint a Nyan cat on another chain, nothing is stopping them, but the Ethereum chain will be given more weight by the community at large because it's the community that spawned the concept in the first place. And the Nyan cat creator publicly announced his NFT sale on Ethereum, so there is provenance.
No, it really can’t. Unless you mean it in a sense that Minecraft is a Turing complete machine and can compute anything you want it to compute. Good luck computing anything non trivial.
A typical car is standing around 90% of the day, if not more. It's a waste of space that could be used for trees, walkways, cycle lanes, etc. If we pooled our resources together and made renting cars easy and accessible, we'd have more space in cities for the people living there.
The physical item still has to be examined by experts on every exchange, if you want to avoid the risk that the legitimate owner of the real thing sells a fake and secretly keeps the real item for themselves. The blockchain can't stop that.
Fear not, the article has you covered (emphasis mine):

> Obviously if you’re FAANG-level or some established site where that 0.1% downtime translates into vast quantities of cash disappearing from your books, this stuff is all great.
Pardon my ignorance re: NFT's, but does anyone verify the status of the person creating the NFT as the owner/creator of the digital art/item in question?
Ethereum gets around the halting problem by using a "gas" model, where it halts your execution if you run out of gas before the program returns.

If Ethereum is actually the PHP of cryptocurrencies, that puts it in a great spot for adoption.
Some of the regulations are pretty weird though - the mirrors in US cars are far worse, and so are lights.
Pretty sure the link the parent (to my comment) provided explains this.

It's not the same kind of runtime reflection people talk about when they (for example) use reflection in Java. It's hidden from the library-using programmer, but the calling needs to "communicate" with the library to figure out data layouts and such, and that sounds a lot like reflection to me.
And if somewhere down that chain someone sells the real artwork to one person and the NFT to someone else? who owns the 'real' artwork - the guy with it on their wall, or the guy with the bits?
I think it just seems like most things surrounding death in the U.S. are in an abysmal state.

Mexico/good portion of the East seem to do things much better regarding it. (These are just the places I'm personally familiar with. Sure there's many others that approach death much differently than the U.S. does as well.)
The form factor of the RasPi is a large selling point for me, and to have more than 1tb, it’s nice to see an option that doesn’t involve a cable or dongle plugged out of the side of the case next to the NIC port. I’m excited to try using this with RaspiBlitz, which requires at least 400 gigs for the blockchain alone.
JavaScript powers much of the Internet today, and PHP too. When evaluating the effect of any given system or protocol - do you only analyze the design of its language - or its outcome?
Wow - this is the most insightful comment and is downvoted????

The key idea - the artist can be the one who creates a market is extremely insightful for me.

It means that the art is an extremely risky value storage since entire market is limited at the moment and may never expand. The number of players in the market is what makes it thrive or disappear.

Of course there are somehow two institutions fueling this market. The author and ethereum users with some visible synergies.
I can't think of a single Ethereum dapp that could be implemented without an expressive scripting language.

Because real world assets don't get minted like crypto. They are tied to physical world. They are volatile. Bitcoin produces a block every 10 minutes. It's a fairly precise schedule. On the other hand, real world assets grow and contract at unpredictable rates. Even gold mining fluctuates. The real world is volatile. The BTCUSD peg is free floating. It's also volatile.

Crypto is rigid. Real world is volatile. It's hard to create a stable peg between crypto and the real world. So some kinds of bridge currencies are necessary. Fiat or some forms of digital fiat will continue to exist.

Bitcoin is a deflationary (disinflationary) asset. The BTCUSD peg is volatile. We need better money instruments to reduce volatility. I think an inflationary crypto can help.
Simple, there exists an open marketplace and game theory suggests that some game developer will figure out that aligning the player's interests with their own will result in a profitable niche for themselves.

You may not necessarily be able to use FFXIV health potion in WoW, but could you imagine that an up and coming 3rd party dev gave you a discount because you had a FFXIV NFT? Could you conceive of a group of indie publishers banning together to create a collaborative ecosystem of NFTs that all their games share and recognize? Could you imagine achievements in certain games unlocking secret levels in others?
Aixam is one manufacturer and based in France as I'm now finding out. The models are relatively expensive, though, because they are not produced in high numbers.
