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

https://t.co/Jtu2e1Q9Em
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 😬

https://t.co/7zvXpQNC2N
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
https://t.co/S3nzWBKXqg
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.

1/ Bitcoin: a bold new world.

Satoshi published the white paper on 10/31/2008. Right at the moment of peak despair during the 2008 financial crisis. Trust had been lost in a world that ran on trust.

2/ But why October 31st? It certainly wasn’t because Satoshi was a fan of halloween, it must have had a deeper meaning. With all of his actions, he demonstrated a careful precision.

He had been working on Bitcoin for at least a year and a half before publishing the white paper.

3/ “I believe I've worked through all those little details over the last year and a half while coding it, and there were a lot of them. The functional details are not covered in the paper, but the sourcecode is coming soon” - Satoshi Nakamoto

4/ On August 18, 2008 Satoshi registers registers https://t.co/rMWwiEwtxT through https://t.co/Uj8lMr10kB.

Satoshi was ready and waiting to hit the send button throughout 2008. What was so special about October 31st?

5/ I believe that Satoshi published the Bitcoin white paper on 10/31 as a hat tip to the ancient Gaelic festival of “Samhain” which was also the date in which Martin Luther nailed his 95 Theses to a church door. Both represent an end of the old and the beginning of the new.

Lots of people are sleeping on one the biggest things @quant_network is currently involved in-ODAP (Open Digital Asset Protocol).

So what is exactly #ODAP and why this makes $QNT one of the most significant and, regarding #crypto mcap, undervalued projects?

Time for a THREAD⬇️


1/ODAP is the protocol for communication between gateways, primarily with an enterprise focus.
So banks, central banks etc. would run a gateway in Overledger Network and ODAP would be the protocol for gateways to communicate with each other in a secure and trustless manner. $QNT


2/ #ODAP Interfaces are the open source connectors that will connect a gateway to #blockchains and any existing network / API. That is based on the standards from work done at ISO TC 307 which 57 countries are working towards.
$QNT CEO Gilbert Verdian is the founder of TC307.


3/We know from the submitted drafts via #IETF (the Internet Engineering Task Force) $QNT is working on #ODAP with:

✅@MIT

✅@intel

but, there’s more to the story as we found out from Gilbert that US Government, Juniper, payment and telecom companies are also there.


4/So how it all started with #ODAP?
Let’s go back to $QNT CEO Gilbert Verdian’s interview with Santiago Velez on #RealVision (October 14th) and try to put all the pieces of the puzzle together.
I’ll forward his words ⬇️

Election day in US; to skip the politics and get straight to the money, here's our quarterly update. How do gold, silver, and government fiat money compare with bitcoin's 21 million? #Bitcoin is the 10th largest money in the world, ex-gold & silver. This is update #10.


2/ Bitcoin's monetary system marches on its continuously-lowering coin emission; meanwhile, other world monetary systems' units inflate, either naturally (like gold & silver ounces), or via monopolistic privilege (like government fiat money "printing").

3/ What follows isn't a lesson in stimulus or bailouts, whatever the world faces. It's an attempt at painting the monetary landscape around the globe. The dollars, euros, and yen we're all familiar with, collectively, are worth $25 trillion. This is an exercise in perspective.

4/ As many know, the response from governments worldwide to Covid-19 has been drastic, so expect big moves. Also interestingly, central banks have been much slower to update their data these days.

5/ Gold & silver is base money of the past. Government fiat is base money today. It comprises both physical cash… and a digital cash component. Bitcoin may be base money of the future. Before we get to the charts, it's important to clarify a few common misconceptions in money.

Go to 1-4 hour chart.

Use the following EMAs.
13,21,50,180.

Look for a period of consolidation and
13>21>50>180.

Wait for a pull back to 13EMA.
If bounce occurs with volume, Enter.

Exit on bearish cross with 21>13.

[1/13] It may be initially confusing to fully grasp how deposits and withdrawals from L1 to @optimismPBC are actually implemented, and it helps to see the on-chain action of what is happening behind the scenes.

[2/13] Initial setup (simplified): on L1 we have SyntheticBridgeToOptimism from Synthetic and OVM_L1CrossDomainManager from Optimism contracts. On L2 we have SynthetixBridgeToBase and OVM_L2_CrossDomainManager contracts.

[3/13] Additionally we have Sequencer (L2 mining node) that verifies all L2 transactions and submits them in batches to L1 for future reference and Relayer that is responsible for relaying messages from L2 —> L1

[4/13] Step 1 - Alice wants to deposit $SNX to L2. To do that she calls initiateDeposit() method on the L1 SyntheticBridgeToOptimism which takes her $SNX, puts it in the escrow and calls OVM_L1CrossDomainManager sendMessage() method.

[5/13] The CrossDomainManager puts this request to CanonicalTransactionChain (this is an “official” and “unmutable” list of all L2 transactions on L1). As a consequence the Sequencer (L2 mining node) will need to execute this transaction on L2.

LING PURANA: IMPORTANCE AND CHARACTERISTICS

Reading Ling Purana provides bhog and moksha to the reader and listeners. It is about Shiva's sermon to Brahma when Shiva entered the Agni Ling and preached about Dharma sidhhi through the stories of Agni Kalp.


Vyasji divided this into two parts. This book is different from others and has eleven thousand shlokas which depict the glory of Shiva. This Puran is the summary about importance of Tridev.
It starts first with a questions. Then it describes the Shrishti in brief.

Then there is description of Yog and Kalp. Next is the evolution of Ling and its puja Vidhi. It consists of dialogue between Sanat Kumar and Shail etc. It also mentions the character of Dadhichi, the dharma representation of that yug, Bhuvan kosh description,

Chandravansh and Surya vansh. Next there is elaborate description of Shrishti, story of Tripur, Ling and Pashu Paash vimoksha, Vrats for Shiva, Discipline, Repentance, Arisht, description of Shri Shail. Next is the story of Andhakasur, Varah, Narsingh,

k¡lling of Jalandhar, Shiv sahastra naam, story of Daksha's yagya and its destruction, killing of Madan and marriage of Parvati.

Next is Vinayak katha, Shiv tandav, Ambrish katha and Upmanyu .

The YouTube algorithm that I helped build in 2011 still recommends the flat earth theory by the *hundreds of millions*. This investigation by @RawStory shows some of the real-life consequences of this badly designed AI.


This spring at SxSW, @SusanWojcicki promised "Wikipedia snippets" on debated videos. But they didn't put them on flat earth videos, and instead @YouTube is promoting merchandising such as "NASA lies - Never Trust a Snake". 2/


A few example of flat earth videos that were promoted by YouTube #today:

Did you know?

Rani Bhabani was the Queen of Natore, Bengal or 'Natorer Rani' as she was famously called. She made great contributions in Tarapith & renovated Benaras.

In Varanasi, Durga Kund Mandir was constructed by Rani Bhabani in the 18th century.


Born in Chhatimgram village, Bogra District,Her father's name was Atmaram Choudhury.Bhabani was married off to Raja Ramkanta Moitra,the then zamindar of Rajshahi.After his death, Bhabani became the zamindar, and started being referred to as Rani.She was known as Ardhabangeshwari.

A woman as a zamindar was extremely rare in those days, but Rani Bhabani managed the vast Rajshahi zamindari most efficiently and effectively for over four decades.
Maharani Bhavani was very pious in her personal life. She passed her life in a strict disciplined way.


She conducted the administrative work skillfully. As a Maharani she was an impartial judge. Rani Bhavani had a very hard time during the fag end of her life. The Zamindari (estate) incurred serious loss due to the change of the revenue policy of the company.

In spite of being the owner of a large Zamindari (estate), she had to depend on the stipend of the government in the later part of her life. The amount of this stipend gradually decreased and became Rs. 1000/- only in the end.

🌺कैसे बने गरुड़ भगवान विष्णु के वाहन और क्यों दो भागों में फटी होती है नागों की जिह्वा🌺

महर्षि कश्यप की तेरह पत्नियां थीं।लेकिन विनता व कद्रु नामक अपनी दो पत्नियों से उन्हे विशेष लगाव था।एक दिन महर्षि आनन्दभाव में बैठे थे कि तभी वे दोनों उनके समीप आकर उनके पैर दबाने लगी।


प्रसन्न होकर महर्षि कश्यप बोले,"मुझे तुम दोनों से विशेष लगाव है, इसलिए यदि तुम्हारी कोई विशेष इच्छा हो तो मुझे बताओ। मैं उसे अवश्य पूरा करूंगा ।"

कद्रू बोली,"स्वामी! मेरी इच्छा है कि मैं हज़ार पुत्रों की मां बनूंगी।"
विनता बोली,"स्वामी! मुझे केवल एक पुत्र की मां बनना है जो इतना बलवान हो की कद्रू के हज़ार पुत्रों पर भारी पड़े।"
महर्षि बोले,"शीघ्र ही मैं यज्ञ करूंगा और यज्ञ के उपरांत तुम दोनो की इच्छाएं अवश्य पूर्ण होंगी"।


महर्षि ने यज्ञ किया,विनता व कद्रू को आशीर्वाद देकर तपस्या करने चले गए। कुछ काल पश्चात कद्रू ने हज़ार अंडों से काले सर्पों को जन्म दिया व विनता ने एक अंडे से तेजस्वी बालक को जन्म दिया जिसका नाम गरूड़ रखा।जैसे जैसे समय बीता गरुड़ बलवान होता गया और कद्रू के पुत्रों पर भारी पड़ने लगा


परिणामस्वरूप दिन प्रतिदिन कद्रू व विनता के सम्बंधों में कटुता बढ़ती गयी।एकदिन जब दोनो भ्रमण कर रहीं थी तब कद्रू ने दूर खड़े सफेद घोड़े को देख कर कहा,"बता सकती हो विनता!दूर खड़ा वो घोड़ा किस रंग का है?"
विनता बोली,"सफेद रंग का"।
तो कद्रू बोली,"शर्त लगाती हो? इसकी पूँछ तो काली है"।
