Out of curiosity I dug into how NFT's actually reference the media you're "buying" and my eyebrows are now orbiting the moon

Short version:

The NFT token you bought either points to a URL on the internet, or an IPFS hash. In most circumstances it references an IPFS gateway on the internet run by the startup you bought the NFT from.

Oh, and that URL is not the media. That URL is a JSON metadata file
Here's an example. This artwork is by Beeple and sold via Nifty:

https://t.co/TlJKH8kAew

The NFT token is for this JSON file hosted directly on Nifty's servers:

https://t.co/GQUaCnObvX
THAT file refers to the actual media you just "bought". Which in this case is hosted via a @cloudinary CDN, served by Nifty's servers again.

So if Nifty goes bust, your token is now worthless. It refers to nothing. This can't be changed.

"But you said some use IPFS!"
Let's look at the $65m Beeple, sold by Christies. Fancy.

https://t.co/1G9nCAdetk

That NFT token refers directly to an IPFS hash (https://t.co/QUdtdgtssH). We can take that IPFS hash and fetch the JSON metadata using a public gateway:

https://t.co/CoML7psBhF
So, well done for referring to IPFS - it references the specific file rather than a URL that might break!

...however the metadata links to "https://t.co/RzXLzsqegH"

This is an IPFS gateway run by https://t.co/yR25JR9mkk, the NFT-minting startup.

Who will go bust one day
You might say "Just refer to the IPFS hash in _both_ places!"

Well ...no. IPFS only serves files as long as a node in the IPFS network _intentionally_ keeps hosting it.

Which means when the startup who sold you the NFT goes bust, the files will probably vanish from IPFS too
In fact, this is already happening: https://t.co/UdUfMuyurw
In short: Right now NFT's are built on an absolute house of cards constructed by the people selling them.

It is likely that _every_ NFT sold so far will be broken within a decade.

Will that make them worthless? Hard to say
"NFT startups are long-game blackmailers" is an entertaining concept

Eagerly awaiting the day when I can buy the bankrupt startup domains and start charging NFT owners to serve their files
"WELL ACTUALLY you just pin the file to your own IPFS node":

You absolutely can! But the metadata file generally points to a specific HTTP IPFS gateway URL - NOT the IPFS hash.

This means when the gateway operator goes bust I can buy the domain and start serving cat pictures
So @CheckMyNFT has been tracking NFTs created on Nifty, and apparently most of them are already broken 😬

I can't believe I have to say this but: Not ALL NFTs

Yes I know there are plenty of NFTs that do not suffer from these problems. I was just covering the mainstream ones that have been hitting the news.

Next time I promise to inject the words "most" and "many" in every sentence
Honestly I'm not just making this up

Apparently it isn't clear and some people are very angry, so:

This thread is specifically criticising the vendors currently selling fragile NFTs, not the concept of NFTs in general. Ok?

Ok.

More from Crypto

1/ Welcome to #DeFi Wednesday.

Let's talk about how interest-bearing cash on a blockchain is going to revolutionise boring corporate treasury management that concerns every company is is a larger business than all crypto trading in the world.

Enter the thread

👇👇👇


2/ Blockchain community is often seen as toxic maxis and redditors who shill other their weekly favourite shitcoin in the hope of getting Lambo.

Sometimes we also do things that progress humanity towards the better future and interest-bearing cash is one of those things.


3/ Less chad and more things that actually matter:

My incomplete theory of interest-bearing cash is also available also as a blog post:

https://t.co/uiG0fZiVyu

It is 15 pages. Pick your slow poison or die fast by continue reading here.

4/ First time in the history we have an ability to create interest-bearing cash-like instruments.

Interest-bearing cash ticks up dollar (euro) balance real-time in your wallet.

Here is a demonstration using @aaveaave aDAI, based on @makerdao DAI, and @TrustWalletApp


5/ Interest-bearing cash is not like your bank's saving account. Your money in a bank is not yours, but bank's. There are some flaws in the current banking system causing a headache for Chief Financial Officers (CFOs)
1/ A thread on Nexgen’s Arrow & the #uranium cycle ($NXE)


2/ Given the scale and cost structure of Arrow, it makes sense that investors are intensely focused on its delivery timeline. This thread will discuss possible timelines, current market expectations (i.e., what’s “priced in”) & how different Arrow scenarios will impact the mkt.

3/ As you can see from the litany of responses to Michael’s tweet, there is great skepticism in the market regarding Arrow’s timeline. This is largely due to a bearish narrative conveyed by competing CEO’s whose assets only hold value if Arrow is substantially delayed.

4/ Those who played “King of the Hill” as a child would remember that it is the person at the top who is constantly attacked, not the kid sitting at the bottom of the hill in the mud. No one cares enough about that kid to attack them. This is a good parable for $NXE & Uranium.

5/ First a quick note on “this cycle” – Segra generally defines this cycle as the deficits forecasted from the mid-2020s to late-2030s. When people imply an asset producing in the mid-to-late 2020s will “miss the cycle”, they clearly have not done any real S/D modelling.

हिमालय पर्वत की एक बड़ी पवित्र गुफा थी।उस गुफा के निकट ही गंगा जी बहती थी।एक बार देवर्षि नारद विचरण करते हुए वहां आ पहुंचे।वह परम पवित्र गुफा नारद जी को अत्यंत सुहावनी लगी।वहां का मनोरम प्राकृतिक दृश्य,पर्वत,नदी और वन देख उनके हृदय में श्रीहरि विष्णु की भक्ति अत्यंत बलवती हो उठी।


और देवर्षि नारद वहीं बैठकर तपस्या में लीन हो गए।इन्द्र नारद की तपस्या से घबरा गए।उन्हें हमेशा की तरह अपना सिंहासन व स्वर्ग खोने का डर सताने लगा।इसलिए इन्द्र ने नारद की तपस्या भंग करने के लिए कामदेव को उनके पास भेज दिया।वहां पहुंच कामदेव ने अपनी माया से वसंतऋतु को उत्पन्न कर दिया।


पेड़ और पौधों पर रंग बिरंगे फूल खिल गए और कोयलें कूकने लगी,पक्षी चहकने लगे।शीतल,मंद,सुगंधित और सुहावनी हवा चलने लगी।रंभा आदि अप्सराएं नाचने लगीं ।किन्तु कामदेव की किसी भी माया का नारद पे कोई प्रभाव नहीं पड़ा।तब कामदेव को डर सताने लगा कि कहीं नारद क्रोध में आकर मुझे श्राप न देदें।

जैसे ही नारद ने अपनी आंखें खोली, उसी क्षण कामदेव ने उनसे क्षमा मांगी।नारद मुनि को तनिक भी क्रोध नहीं आया और उन्होने शीघ्र ही कामदेव को क्षमा कर दिया।कामदेव प्रसन्न होकर वहां से चले गए।कामदेव के चले जाने पर देवर्षि के मन में अहंकार आ गया कि मैने कामदेव को हरा दिया।

नारद फिर कैलाश जा पहुंचे और शिवजी को अपनी विजयगाथा सुनाई।शिव समझ गए कि नारद अहंकारी हो गए हैं और अगर ये बात विष्णु जी जान गए तो नारद के लिए अच्छा नहीं होगा।ये सोचकर शिवजी ने नारद को भगवन विष्णु को ये बात बताने के लीए मना किया। परंतु नारद जी को ये बात उचित नहीं लगी।
Fake chats claiming to be from the Irish African community are being disseminated by the far right in order to suggest that violence is imminent from #BLM supporters. This is straight out of the QAnon and Proud Boys playbook. Spread the word. Protest safely. #georgenkencho


There is co-ordination across the far right in Ireland now to stir both left and right in the hopes of creating a race war. Think critically! Fascists see the tragic killing of #georgenkencho, the grief of his community and pending investigation as a flashpoint for action.


Across Telegram, Twitter and Facebook disinformation is being peddled on the back of these tragic events. From false photographs to the tactics ofwhite supremacy, the far right is clumsily trying to drive hate against minority groups and figureheads.


Declan Ganley’s Burkean group and the incel wing of National Party (Gearóid Murphy, Mick O’Keeffe & Co.) as well as all the usuals are concerted in their efforts to demonstrate their white supremacist cred. The quiet parts are today being said out loud.


The best thing you can do is challenge disinformation and report posts where engagement isn’t appropriate. Many of these are blatantly racist posts designed to drive recruitment to NP and other Nationalist groups. By all means protest but stay safe.
