This was one of the most interesting (and challenging) posts in this series for me to write.

Why? Because NFT’s are the single topic in the crypto world that I most radically changed my mind about—from thinking they were ridiculous to believing they have a huge amount of potential.

I’m excited to explain.

But first:

Let’s quickly review Ethereum (and add a few more details) to make sure you understand before we continue.

Last time, I explained some key concepts:

  • Ethereum is the most popular cryptocurrency after Bitcoin. It works like a multipurpose vending machine, allowing you to easily pay ETH (Ethereum) to purchase one of the items being offered.
    • The “vending machine slots” are all dapps (decentralized apps) containing smart contracts, so when you “buy something,” you’re triggering that dapp to run.
    • Anyone can create a new dapp to be offered via the “vending machine” since the dapps run directly from websites (there’s no app review process like with the Apple app store).
    • In other words, when I use the “vending machine” analogy, I’m talking about something on the scale of the Internet, with each website or smartphone app being a “vending machine slot.”
  • One Ethereum use case is Oracles. These are dapps or protocols (i.e., sets of rules that allow information to be shared between computers) that pull in information from outside the blockchain such as weather reports, sports scores, or stock prices.
  • Another Ethereum use case is DEX’s (decentralized exchanges) and CEX’s (centralized exchanges). These offer users a way of easily exchanging one coin or token for another.
  • Coins vs. tokens: A coin is specifically related to currency or payment, and it uses its own blockchain.
    • For example, BTC (Bitcoin) is a coin because it doesn’t do much other than store value, and it runs on the Bitcoin blockchain. A token, on the other hand, could also be used for payment, but it’s programmable too, so it can do a lot more than that.
    • Another example: SUSHI is the token for the SushiSwap DEX, and it runs on the Ethereum blockchain. So, if you have some SUSHI in your wallet, it not only has value as a currency, but it also helps keep the SushiSwap dapp running (which manages over $3B USD).
  • Tokens that run on the Ethereum blockchain specifically are called ERC-20 tokens. There are hundreds of thousands of these (including SUSHI) that offer all sorts of functionality.
    • (Incidentally, NFT’s, which we’re about to talk about, are ERC-721 tokens, which are similar to ERC-20’s—since they run on Ethereum as well—except ERC-721’s are non-fungible. You’ll learn what that means shortly.)

Because it’s programmable like a computer, Ethereum has a huge number of potential use cases. So far, the two big ones we’ve covered are oracles and exchanges.

Next, we’ll spend the rest of this post (and the next couple as well) exploring another major use case (one that’s been exploding in popularity lately): NFT’s.

Ethereum use case #3: NFT’s (non-fungible tokens)

Put simply, NFT’s are unique digital assets.

That could mean anything from a piece of art, to a digitized DNA sequence, to a weapon in an online video game world, to a virtual pet, to a digital file representing the deed of a house.

What does NFT stand for? “Non-fungible token.”

Let’s break that down:

Remember that a token is a kind of programmable cryptocurrency that lives on an existing blockchain, most often Ethereum.

The word “fungible” basically just means “interchangeable” or “non-unique.”

For example, a dollar bill is fungible because it doesn’t matter which specific dollar bill you have—they’re all basically the same.

In contrast, your birth certificate is non-fungible—there’s only one, and you can’t just swap yours for someone else’s. An original painting is also non-fungible since a print of it would be considered a copy and not an original.

So, an NFT is a unique (non-fungible) thing, except it’s not a physical object—it’s stored digitally.

When I say “unique” here, we’re talking about a digital asset that’s cryptographically signed and stored on the blockchain (typically the Ethereum blockchain).

So when you buy an NFT, it’s not just a seller telling you it’s unique—it’s proveably unique (and you can easily check the blockchain to be sure).

In other words, think of a file on a computer that you can’t just copy and paste. A file that would remain completely one-of-a-kind.

This is going to seem ridiculous at first, but I hope you’ll give me a chance to explain.

Unfortunately, NFT’s have developed a bit of a bad reputation with the general public thanks to silly stories in the mainstream media. For example, news stories will focus on how someone sold a tweet as an NFT in a way that makes it sound ridiculous. And because of that, when I first heard about NFT’s, I found myself super skeptical as well.

Even now, I certainly wouldn’t call myself an NFT enthusiast. But, I’ve come around quite a bit after a lot of reading and listening, and I now believe that this topic is significant enough to spend a good amount of time on it.

So I want to preface all of this by saying: I get it. A lot of this is going to seem ridiculous at first. But if you give it a chance, you might be surprised that this goes a lot deeper than it seems on the surface.

Let’s dive in: Why should you care about NFT’s?

First, since the term “NFT” covers so many different types of things, here’s what I suggest: Start by thinking of NFT’s as digital trading cards or special pieces of art—except, instead of being physical objects, they’re accessed via your Ethereum crypto wallet, and they live on the blockchain just like other cryptocurrencies.

NFT’s have a few attributes that make them special:

They’re provably unique, which is a fairly new concept in the digital world.

Remember why blockchain technology is so good at verifying financial transactions: Because every single transaction for all time is carefully verified and logged on the blockchain, then copied to thousands of computers all over the world. That makes it incredibly resistant to fraud, censorship, and so on.

So, if my Bitcoin wallet shows that someone sent me 50 BTC at 3:47 pm yesterday, you can trust that that’s completely accurate—all without having to contact a central bank, lawyer, or some other traditional authority figure.

Now, apply that concept to the digital trading card or art analogy—when you see that someone has an NFT in their wallet, you can absolutely trust that they’re the real owner and that what they own is completely unique.

Again, it’s truly one-of-a-kind and can’t simply be copied and pasted.

NFT’s can have both ownership and royalties (as well as all sorts of other attributes) programmed in.

With a traditional piece of art or digital creation, once the creator sells it, that’s where their compensation ends.

Since NFT’s are programmable and live on the blockchain, you can look up the record of who originally created that NFT and who currently owns it (or at least their wallet address).

The original creator can even program the smart contract so that they get a cut of the sale whenever that NFT changes hands in the future.

Let’s pause for a moment and consider how amazing this is. In the physical world, if an artist sells a painting, they have no idea what happens to it once the buyer walks away. But with NFT’s, anyone can track which wallet currently owns them, what their current value is, and their entire history of ownership.

This could be a game-changer for the art industry. Imagine an artist who sold a piece of their art that later exploded in popularity. That original buyer could now sell it for a lot of money and the artist would get a piece of the profit.

With me so far? Now, apply all of that to pretty much anything that can be represented digitally:

  • Say you release a video that goes viral. In the pre-NFT world, you might not have typically received any compensation for it. But, what if there were a YouTube-like service where each video were an NFT tied back to its original creator? And what if that service were governed in a decentralized way rather than being filtered through the Google corporate machine?
  • Say a scientific researcher writes an influential paper that ends up been cited hundreds of times by other scientists. What if they received a small amount of compensation each time?
  • We’ll go over a lot more possibilities shortly, encompassing collectibles, music, art, and more.

This whole NFT world is so new that we’re just scratching the surface of what’s possible, and the community is still figuring out what does and doesn’t make sense as an NFT (which is why you might come across some that seem especially ridiculous or useless).

The creator of Ethereum actually tweeted recently that NFT’s are the Ethereum use case that most surprised him.

There’s a lot of potential here. And over the next few posts, we’ll explore some major categories of NFT’s that are already popular, starting with collectibles.

Category #1: Collectibles

Personally, I’ve never been much of a collector. But I know people who are. So right off the bat, please try to notice if any skepticism you feel in this section is about NFT’s specifically or about the idea of collecting something in general.

Let’s start with the assumption that collecting is a reasonable hobby—for example, baseball cards, stamps, comic books, dolls, Magic: The Gathering cards, and so on.

If you’re not familiar with it, Magic: The Gathering is a collectible card game that’s been around since 1993. It’s been incredibly popular, with more than 35 million players. The most prized card, the Black Lotus, sold in January 2021 for $511,100 USD.

Black Lotus card

Because Magic has been around for so long, over a dozen new sets (or “editions”) of cards have been printed over the years. Often, the same card appears in multiple editions, but its value can vary dramatically depending on the age and rarity of a given edition.

For example, a Beta Edition version of the Mana Vault card is valued at over $9,000 USD, whereas a 4th Edition version of that same card (released only two years later) is valued at only $71 USD.

From a gameplay perspective, they’re the exact same card. But from a collectibles perspective, it’s critical to know which edition of a card you’re getting.

This applies to all sorts of collectibles.

Two pieces of fine art might look the same to the untrained eye. But, a careful inspection by an expert might reveal that one is an original from three hundred years ago and the other is a forgery made by a skilled artist twenty years ago. Even though it took a close inspection to see the difference, those two pieces still have dramatically different values.

Whether you’re dealing with art, comic books, baseball cards, or whatever else, the value of a given object depends on things like:

  1. If it’s legitimate (not a forgery),
  2. How old it is, and
  3. How rare it is.

But how can you know those things for sure?

To check the legitimacy and age, you could hire an expert to inspect the object for you. And for rarity, you could try to research how many were originally printed, but it might be iffy to get at a conclusive number.

What if you thought you owned a rare comic book but it turned out that many thousands of them had been printed?

NFT’s make all of this a whole lot easier.

For any NFT, you can simply open up its record on the blockchain and see exactly when it was made, how many copies of it were created, and the exact path it took to get where it is now (i.e., who first created it, who bought it from whom, etc.).

(Technically, you’ll just see the trail of wallet addresses rather than actual people. But, if you want to buy an NFT and aren’t sure who the owner is, there are various online marketplaces and discussion groups you can use to try to track them down.)

As we keep moving toward a truly digital-first world, will that destroy the concept of collectibles?

Nowadays, a lot of people are already reading books exclusively on their Kindles rather than the print editions. What if that trend continues and comic books and trading cards become purely digital too?

If that seems clumsy or far-fetched, imagine the tech we’ll have a decade from now: cheap, paper-thin, bendable screens with huge battery life.

Think about how both work and play have moved increasingly online during the pandemic. A lot of people want to be able to play games with friends or strangers who live far away, and that’s probably not going to dramatically change even when things go back to “normal.”

Well, a popular online version of Magic: The Gathering already exists alongside the paper version. And because the collecting aspect (including the concept of rarity) has been such an important part of the Magic experience, that was carried over into the digital version as well. In other words, long before NFT’s existed, digital Magic cards already had certain rarity values assigned to them, and they were worth real money.

NFT’s still represent something new here.

Let’s explore a few different ways that collectibles (and rarity) could work in the digital world.

When it comes to digital assets like virtual trading cards, I see three main directions things could move in:

  1. The concept of rarity disappears, and therefore the entire hobby of “collecting things” disappears as well. There’s no longer a concept of an “original run” version of a card or a “special edition” version of a comic book. Instead, there’s an infinite supply of formerly-rare Black Lotus cards, and they’re all exactly the same.
  2. We increasingly rely on centralized DRM (digital rights management). This is how most streaming music, TV, and movie services work today, and it will remain the most likely situation if crypto fails. If that seems like no big deal, think about all the issues that exist around not “truly owning” the digital products you buy:
    1. For example, what happens to all your music if Spotify dies? What happens to all your ebooks if Amazon decides to ban the smartphone you read them on for some reason? Each of these companies likely promises that they’d find a positive solution if their company went bankrupt, but the point is that they have complete power to decide what happens to the music, movies, books, TV shows, and so on that you paid for.
    2. With DRM tech, they’re able to modify or remove the digital assets that live on your phone without your permission (here’s a story about someone who had all their paid-for books remotely wiped from her device by Amazon—with no real explanation or opportunity to appeal the decision).
    3. If you carefully read the user agreements on all these services, you’ll find that you don’t actually own the book, song, TV show, etc. you bought—only a limited license to it.
  3. Blockchain-based NFT technology allows users to actually own the thing. Plus, it has a built-in “certificate of authenticity”—there’s an indisputable record of where the person got it along with any other relevant information. You can confirm that the NFT is an original and that it has a certain level of rarity—all without needing to get third parties involved.

So no, a digital-first world doesn’t have to destroy the concept of rarity or the practice of collecting things.

But how does the concept of rarity actually apply to digital items? Aren’t digital items infinitely copyable?

Maybe, maybe not.

With NFT’s, someone might create a new collectible trading card game and decide to make two versions of the same card.

Those two versions might look exactly the same except for one thing:

  • One is part of a “first run set of 5” (i.e., rare), so it has a little “#3 of 5” written in the corner or in the metadata of the card.
  • The other is part of a “second run set of 5,000” (i.e., common), so it has a little “#289 of 5,000” written on the card or in the metadata.

Because of that, if the new game becomes popular, it’s very likely that the rare first run set will end up being worth a lot more money than the common second run set.

You might be thinking: “This is ridiculous—it’s the same card! How can one be common and one be rare just because the creator says they are? They’re all just digital copies of the same thing, and digital things could technically be duplicated a million times with no loss of quality, so the idea of rarity doesn’t make sense.”

Possibly, and it’s certainly a philosophical debate.

But we humans do seem to enjoy the concept of rarity in general, even if the functionality is pretty much identical. So, philosophically, one might say that there would be something sad about moving to a highly digital world where everything is infinite and it’s no longer possible to feel like you own something precious and special.

NFT’s allow us to retain that feeling of preciousness—even in a digital world.

Plus, as you’ll see below, there’s a lot of cool stuff that can be done with NFT’s to make the concept of rarity seem less artificial and more interesting.

There’s more to this. Remember how Ethereum is fully programmable?

People already enjoy collecting sports cards just for the collectible aspect. But, if you’re a sports fan, imagine playing fantasy football with NFT-based collectible trading cards that respond to real-world events.

Imagine if the card for each football player were programmed to automatically change its stats (and rise or fall in value) as that person became more famous, broke records, or won championships.

Let’s go even further: What if NFT trading cards weren’t just trading cards?


In May 2021, popular entrepreneur and digital marketer Gary Vaynerchuk released an NFT collection called VeeFriends.

VeeFriends is a collection of 10,255 NFT’s that look like trading cards. They all feature artwork drawn by Gary and can be collected and traded just like any normal, limited-run collectible.

But Gary went a step further by giving many of the cards special attributes that connect to real-world rewards. For example:

  • The “Admission” cards give the holder access to Gary’s high-end in-person conference for as long as they hold it (up to three years).
  • The “One-on-One” cards give the holder access to specific activities with Gary, like a mentoring session, a podcast appearance, or even a basketball game with him and his friends.
  • The “Gift Goat” cards put you on Gary’s list to be sent physical gifts in the mail six times a year.

Dinner Deer

(Those numbers on the bottom-right are prices in Ethereum. Yes, Dinner Deer sold for over $30,000 USD.)

What’s interesting about these cards is that they’re a combination of (1) admission ticket or subscription service and (2) collectible or investment.

Gary hasn’t actually held a conference or sent out gifts yet, so no one knows how desirable those will end up being. If they flop, the value of the NFT’s will go down; but, if they turn out to be awesome—and these limited NFT’s are the only way to access them—the value of the NFT’s will rise, and the NFT owners will have to decide if they want to sell them or hang onto the cards to continue getting rewards.

VeeFriends are the first example of this kind of thing I’ve seen, but I imagine this will become increasingly popular in the future.


Another example of trading cards with real functionality behind them is CryptoKitties. These are more like a cross between collectible cards and virtual pets.

They were one of the first collections of NFT’s to get people excited since they were cute, collectible, and had a game element to them: You can “breed” two CryptoKitties you own to create a new kitten that takes on some of the characteristics of each parent.

Some characteristics are more rare than others, so each time you breed, you’re rolling the dice in terms of how valuable your new kitty will be.

Category #2: Research Funding and Historical Significance

This category is highly experimental right now, but I wanted to briefly include it since it hints at some of the ways NFT’s might be useful beyond just the most common use cases of collectibles and art.

In June 2021, UC Berkeley auctioned some documents related to Nobel Prize-winning research around an immunotherapy breakthrough and CRISPR gene editing discovery.

It wasn’t simply a scientific paper that was being auctioned, but related documents like handwritten annotations that the scientists thought would be interesting to the public and of historical significance. Sure, they could have just released all that as a standard PDF that can be copy and pasted, but this way it’s all packaged into a unique NFT that a single person now owns.

It ended up selling for nearly $55,000, and this model could represent a way of funding scientific research in the future.

Science NFT

Category #3: Music

The music NFT space is still very young, but there’s huge potential there.

Ever since we transitioned from CD’s to MP3’s (and likely even before that), proper compensation has been tricky for musical artists. Spotify pays them as little as $.0033 per stream.

What if an artist could set the price of an NFT of their song, and the smart contract would ensure they were paid, even without a middleman like Spotify, Apple, or a traditional publisher?

Again, this space hasn’t been very developed yet, but here are some possibilities that don’t seem too far away:

  • Smart contracts where a musician could encode different price points and compensation options—maybe regular consumers pay one price, but production companies pay a different one to feature that song in their commercial or movie.
  • Maybe the artist generates a list of everyone who owns a copy of their song NFT, and they somehow feature those fans during a live concert. Maybe all their names appear on the screen, or maybe those owners get free access to the recording of the live version of the song afterward.
    • Sure, things like Patreon already exist today, but that’s another centralized service. With NFT’s, the artist could easily check the Ethereum blockchain to find the wallet addresses of everyone who purchased their NFT. Then, the artist could send each fan a special token that would appear in their wallet, all without needing to rely on a company like Patreon, Ticketmaster, or a music publisher. That way, the artist isn’t locked into the rules and whims of a central entity like Patreon for their livelihood. They’re free to take their list of fans with them to any blockchain-based platform.
  • Theoretically—once the legal structures are worked out—there could be a complex smart contract like this:
    • You’re a superfan who buys partial ownership of a song from a less well-known artist. Eventually, that song gets featured in a commercial and explodes in popularity. Now, not only does the original artist get compensated, but you get a piece of the profit too since you believed in it early on and were willing to invest in it before it was popular.

The ecosystem isn’t quite to that level of sophistication yet.

But, the band Kings of Leon announced in March 2021 that their new album, When You See Yourself, would have an NFT version. Fans who purchase that version will get perks like front-row seats for life at live shows, a VIP experience with exclusive merchandise, etc.

When You See Yourself

Generative Music

Another completely different category of audio NFT is generative music—music created by a computer according to rules laid out by the artist-programmer.

DeafBeef is one example. It’s a generative music NFT that’s created at the time of purchase based on a random value that seeds various attributes like tempo, timbre, and pitch. (The music doesn’t change after that initial creation, at least in the case of DeafBeef.)

In other words, every single buyer gets a completely unique piece of music, and they can’t preview it before buying because it doesn’t exist yet. DeafBeef is all fully on-chain (i.e., “on blockchain”), meaning it’s not just linking to an MP3 stored on a server somewhere; it’s generating the sounds in real-time based on code stored on the blockchain.

Not only that, but this music will never be lost unless the entire Ethereum blockchain is shut down.

You can browse DeafBeef and listen to what it sounds like here.

This post got so big that I decided to split it into three. In the next part, we’ll explore some more NFT use cases: art, video games, online worlds, and the future of virtual reality.

6 Comments on “Easing into Crypto, Part 9: Intro to NFT’s (collectibles, research funding & historical significance, and music)”

  1. Parts 9-12 were really interesting and expanded my idea of the range of potential uses of NFTs. Thanks! Some questions:

    – The article at https://slate.com/technology/2021/04/nfts-digital-art-authenticity-problem.html casts doubt on whether NFTs actually do what people seem to thin they do. Do you think that’s somehow a misunderstanding of NFTs?

    – This whole idea of “ownership” of an item based on owning its NFT is just an honor system (unless people eventually create legal agreements to formalize the NFT-object relationship), right? So if you own the NFT for a piece of digital art but someone else makes a verbatim copy of that art and uses it as the cover of their new book and sells a million copies of it, you or the artist might try to shame them about it, but you couldn’t sue them, because to the law, you may own the NFT that refers to the art, but you have no legal rights to the art itself?

    – In the CRISPR document example, do you know whether the NFT included a digital image of the documents, and the university is otherwise keeping them hidden, so only the purchaser could view them unless they (or the university) later decided to publish them somewhere, so they bought the ability to view the documents and the option to sell the ability to view them to someone else in the future? Or are the documents already public and basically they chose to pay $55K as a colorful way of donating $55K to science?

    – Some use cases have people getting off-blockchain perks for owning an NFT. I see how that could work if the perk could be delivered as a digital key, like sending a code to a fan’s wallet to give them access to a front-row seat. But how could someone prove they–as a person, not as a wallet–own an NFT? E.g., how does the person who (claims to) own the wallet that purchased Dinner Deer prove to Gary V. that he should send them the gift? I guess Gary could send a code to their wallet that would give them access to a website where they could send him their street address for the delivery?

    Btw, in part 11, where you wrote “All of this is non-custodial, meaning you’re actually sending…” I think you meant “you’re *not* actually sending…”

    1. Those are very valid observations and questions.

      I imagine the answer to a lot of this is: The crypto/NFT community is still figuring it out. We’re in the experimentation phase just like with the early Internet when a lot of websites tried out different business models and some succeeded but a lot ended up failing.

      It does seem like a lot of this relies on the honor system. Indeed, as far as I can see, nothing can stop an artist from promising that something is a limited edition and then simply releasing another one later.

      But that’s the same in the traditional art world. Certainly, it would apply less to a physical painting since the artist would have to recreate it, which would require a lot of hours. But, say they made a “limited edition” set of 10 woodblock prints, sold them as 1 of 10, 2 of 10, etc.; then, once those were all sold, they used the same woodblock to print 10 more. I’m by no means an art expert, but I imagine the only thing stopping that is ethics plus the artist’s reputation—if collectors realized the artist was doing that, I would expect their work to go down in value.

      With NFT’s, it would be even easier to see if an artist were doing that since the new copies would likely go up for sale on a popular digital platform like OpenSea, which is easily searchable.

      So yes, I suppose the only thing stopping an NFT creator from simply creating copies of their work is their reputation and the fact that the previous copies would likely be devalued.

      In terms of actual law, you’re absolutely right that buyers and sellers are on their own here. Again, not a legal expert, but my understanding is that none of this would be protected by law enforcement in the same way that there’s not much you can do to recover your BTC or ETH if you lose your private key.

      But again, remember that these are the very early days. And where do we go from here? It seems highly unlikely that humanity won’t keep moving more and more into the digital realm with technologies like virtual reality and online gaming worlds. So the law will have to catch up to treat digital goods as real and valuable (and thus worthy of legal protection as well). It seems only logical that we’ll need a mechanism for making digital assets unique (and worth real money) once it becomes more common to spend a lot of time (including working for pay) in digital worlds.

      NFT’s are the best solution to that problem that I’ve seen (with the only real alternative being DRM, which is controlled by corporations and not open source and decentralized).

      I don’t know much about those CRISPR documents beyond what I read in a news story. But there are similar examples as well like Tim Berners-Lee selling source code from the original World Wide Web as an NFT (and it included not just the code itself, but a video, a letter from him, etc.). Again, I’m not sure exactly what happened there, but I imagine it would be devalued if all of those bundled items were easily downloadable from his website.

      At the same time though, NFT’s are all living on the public Ethereum blockchain; so, as far as I understand it, anyone can view everything that’s included with any NFT. The actual ownership then is more like bragging rights plus some extra privileges like Gary V.-style rewards or the ability to display a piece of NFT art in physical art frames that are programmed to only show art that lives in the owner’s wallet. And, this kind of ownership will only get more important with online digital worlds and VR when people want to be able to show that they own a genuine Louis Vuitton digital handbag, a magical sword with special attributes in a game world, etc.

      Good question about how the Gary V.-type rewards would work. My guess is that it would involve using your private key to cryptographically sign something. For example, when I place a vote in a DAO, I prove it’s me by signing my vote with my wallet. So, I’m not sure exactly what Gary is planning, but I imagine it could be something like a form on his website that says “fill out your home address and then click here to connect your wallet and sign your submission.”

      Thanks for pointing out that typo in part 11 too.

      1. Thanks, all good points. NFTs still seem pretty insubstantial to me, but I can see how they could be wonderful for artists and other creators, especially if they start to gain legal recognition.

        1. Thanks! By the way, based on your helpful comments, I added two new sections:

          One starting with “Couldn’t the artist cheat you? How can you trust that an NFT is truly unique?” on https://www.michaelcaloz.com/2021/07/31/easing-into-crypto-part-10-more-categories-of-nfts-art-video-games-virtual-reality/

          And one starting with “One more point here: A critical part of many NFT collections is the community surrounding them.” on https://www.michaelcaloz.com/2021/08/01/easing-into-crypto-part-11-wrapping-up-nfts-what-you-can-actually-do-with-them-upsides-downsides-risks/

  2. I also wonder about the legal status of crypto coins themselves. For example, in the recent polynetwork hack, even if they found the identity of the hacker and someone wanted to prosecute, are there laws that even recognize data on a blockchain or knowledge of a private key as conferring legal “ownership” of a virtual thing that could then be “stolen”?
