Check out: OurBigBook.com, the best way to publish your scientific knowledge. It's an open source note taking system that can publish from lightweight markup files in your computer both to a multi-user mind melding dynamic website, or as a static website. It's like Wikipedia + GitHub + Stack Overflow + Obsidian mashed up. Source code: github.com/ourbigbook/ourbigbook.
Sponsor me to work on this project: 100k USD = I quit me job and work on it one year full time. Status: ~144k / 200k USD reached: 1st year locked-in, 2nd year stretch goal open at 200k USD. 1M USD = I retire and do it forever. How to donate: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
I reached 100k USD after a 1000 Monero donation, so I quit my job for 1 year starting 1st June 2024 to solve as many STEM courses as I can from a world leading university to try and kickstart The Higher Education Revolution. If I reach 200k USD, then I'll do it for two years instead. A second year greatly improve chances of success: year one I solve a bunch of courses, year two I come guns blazing with the content and expand further.
Mission: to live in a world where you can learn university-level mathematics, physics, chemistry, biology and engineering from perfect free open source books that anyone can write to get famous. More rationale: Section "OurBigBook.com"
Explaining things is my superpower, e.g. I was top user #39 on Stack Overflow in 2023[ref][ref] and I have a few 1k+ star educational GitHub repositories[ref][ref][ref][ref]. Now I want to bring that level of awesomeness to masters level Mathematics and Physics. But I can't do it alone! So I created OurBigBook.com to allow everyone to work together towards the perfect book of everything.
My life's goal is to bring hardcore university-level STEM open educational content to all ages. Sponsor me at github.com/sponsors/cirosantilli starting from 1$/month so I can work full time on it. Further information: Section "Sponsor Ciro Santilli's work on OurBigBook.com". Achieving what I call "free gifted education" is my Nirvana.

Artist unknown, uploaded December 2014. Part of Section "Cool data embedded in the Bitcoin blockchain" where Ciro Santilli maintains a curated list of such interesting inscriptions.
This was a small project done by Ciro for artistic purposes that received some attention due to the incredible hype surrounding cryptocurrencies at the time. Ciro Santilli's views on cryptocurrencies are summarized at: Section "Are cryptocurrencies useful?".

JPG image fully embedded in the Bitcoin blockchain depicting some kind of cut material art depicting a yellow robot, inscribed on January 29, 2017.
Ciro Santilli found this image and others during his research for Section "Cool data embedded in the Bitcoin blockchain" by searching for image fingerprints on every transaction payload of the blockchain with a script.
The image was uploaded by EMBII, co-creator of the AtomSea & EMBII upload mechanism, which was responsible for a large part of the image inscriptions in the Bitcoin blockchain.
The associated message reads:
Chiharu [EMBII's Japanese wife] and I found this little yellow robot while exploring Chicago. It will be covered by tar or eventually removed but this tribute will remain. N 41.880778 E -87.629210
This is one of Ciro Santilli's favorite AtomSea & EMBII uploads, as it perfectly encapsules the "medium as an art form" approach to blockchain art, where even non-novel works can be recontextualized into something interesting, here depicting an opposition between the ephemeral and the immutable.
At twitter.com/EMBII4U/status/1615389973343268871 EMBII announced that he would be giving off shares of that image on Sup!?, a Bitcoin-backed NFT system he was; making. In December 2023, he gave some shares of the robot to Ciro Santilli.

This website was used as one of the CIA 2010 covert communication websites, a covert system the CIA used to communicate with its assets. More details at: Section "CIA 2010 covert communication websites".
Ciro Santilli had some naughty OSINT fun finding some of the websites of this defunct network in 2023 after he heard about the 2022 Reuters report on the matter, which for the first time gave away 7 concrete websites out of a claimed 885 total found. As of November 2023, Ciro had found about 350 of them.
Figure 5. .
This is another website that was used as one of the CIA 2010 covert communication websites. This website is written in Brazilian Portuguese, and therefore suggests that the CIA had assets in Brazil at the time, and thus was spying on a "fellow democracy".
Although Snowden's revelations made it extremely obvious to the world that the USA spies upon everyone outside of the Five Eyes, including fellow democracies, it is rare to have such a direct a concrete proof of it visible live right on the Wayback Machine. Other targeted democracies include France, Germany, Italy and Spain. More details at: USA spying on its own allies.

A quick 2D continuous AI game prototype for reinforcement learning written in Matter.js, you can view it on a separate page at cirosantilli.com/_raw/js/matterjs/examples.html#top-down-asdw-fixed-viewport. This is a for-fun-only prototype for Ciro's 2D reinforcement learning games, C++ or maybe Python (for the deep learning ecosystem) seems inevitable for a serious version of such a project. But it is cute how much you can do with a few lines of Matter.js!

Bitcoin Forum Updated +Created
Good article about its history: en.bitcoin.it/wiki/BitcoinTalk

bitcoin.org Updated +Created
Official Bitcoin domain registered by Satoshi Nakamoto.
Registration: 2008-08-18 by www.namecheap.com, an American company. But using a privacy oriented registrar: bitcoin.stackexchange.com/questions/89532/how-did-nakamoto-untraceably-pay-for-registering-bitcoin-org It is unknown how he could have paid anonymously, so it seems likely that the true identity could be obtained by law enforcement if needed.

BitcoinStrings.com Updated +Created
bitcoinstrings.com has all strings -n20 strings, we can obtain the whole thing and clean it up a bit with:
wget -O all.html https://bitcoinstrings.com/all
cp all.html all-recode.html
recode html..ascii all-recode.html
awk '!seen[$0]++' all-recode.html > all-uniq.html
awk to skip the gazillion "mined by message" repeats.
A lot of in that website stuff appears to be cut up at the 20 mark. As shown in Force of Will, this is possibly because they didn't use -w in strings -n20, and the text after the newlines was less than 20 characters.
That website can be replicated by downloading the Bitcoin blockchain locally, then:
cd .bitcoin/blocks
for f in blk*.dat; do strings -n20 -w $f | awk '!seen[$0]++' > ${f%.dat}.txt; done
tail +n1 *.txt
Remove most of the binary crap:
head -n-1 *.txt | grep -e '[. ]' | grep -iv 'mined by' | less

Cool data embedded in the Bitcoin blockchain Updated +Created
This is a collection of cool data found in the Bitcoin blockchain using techniques mentioned at: Section "How to extract data from the Bitcoin blockchain". Notably, Ciro Santilli developed his own set of scripts at github.com/cirosantilli/bitcoin-inscription-indexer to find some of this data. This article is based on data analyzed up to around block 831k (February 2024).
Drop some Bitcoins at 3KRk7f2JgekF6x7QBqPHdZ3pPDuMdY3eWR if you are loaded and like this article in order to support some much needed higher educational reform: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
When this kind of non-financial data is embedded into a blockchain some people called an "inscription". The study or "early" inscriptions had been called a form of "archaeology"[ref][ref]. Since this is a collection of archeological artifacts, we call it a "museum"!
One really cool thing about inscriptions is that because blockchains are huge Merkle trees, it is impossible to censor any one inscription without censoring the entire blockchain. It is also really cool to see people treating the Bitcoin blockchain basically like a global social media feed!
Starting on December 2022, ordinal ruleset inscriptions took the bitcoin blockchain by storm, and dwarfed in volume all other previous inscriptions. This museum focuses mostly on non-ordinals, though certain specific ordinal topics that especially interest he curators may be covered, e.g. Ordinal ruleset inscription porn and ordinal ASCII art inscription.
Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) is a mandatory precursor to this article and contains the most interesting examples of the time. But much happened since Ken's article which we try to cover. This analysis is also a bit more data oriented through our usage of scripting.
Artifacts can be organized in various ways:
In this article we've done a mixture of:
  • themes: if multiple items fall in a theme, we tend to put it there first
  • then by media type if they don't fit any specific theme
  • then by encoding
  • and finally chronologically within each section
Who said it was easy to be a museum curator!

The cool thing about this image is that it highlights the striking parallels between the encoding of the Arecibo message with crypto graffiti, because in both cases people were creating undocumented new ways of communicating with strangers on a new medium in those early blockchain days.
The associated message contains the Arecibo message as ASCII 0's and 1's. When properly cut at the newlines, they draw the message as ASCII art, as the original Arecibo encoding intends, here's a version with the 0's replaced by spaces to make it more readabale:

This is a relatively unusual AtomSea & EMBII upload as it does not have the common toplevel transaction, everything, text + image fits into a single transaction. This is perhaps why the image is relatively low resolution to have a smaller size.

Ordinal ASCII art inscription Updated +Created
This is a quick overiew of ASCII art ordinal inscriptions.
It was obtained by casually scrolling down the list of the largest text ordinal inscription on less until patience ran out.
Some of them are dedicated ASCII art inscriptions, others are just small highlights to other more important text like code.
Although tere is some element of commercialism in some those inscriptions, a bit like what is rampant in the images, some of them are honestly just cool and possibly novel.
Ordinal ruleset inscription collections:
  • Humongous surfers. These are very large ASCII arts, by far the largest on the chain. Being so large allows for shades of gray to be encoded on the average luminosith of individual letters:
  • Michael Jackson Unicode art. Uses Unicode Braille characters. Marked "First Onchain Collection" and "Legends @ BTC" . Pretty cool design, the textures are quite cool and suggest glittering flying seat. Though if those ever sell, someone is going to get sued to Hell by MJ's estate!

Ordinal ruleset inscription porn Updated +Created
These were found by running object detection software for some porn/nudity detection. We need to run some more, all sex was likely missed: github.com/GantMan/nsfw_model/issues/160
Raw images Updated +Created
In this section contains a list of images we could find that wre uploaded as raw data to the blockchain, without any special encoding, e.g. as done by the AtomSea & EMBII system.
It is possible that some/most of those were uploaded via the cryptograffiti.info system, but since that indexer stopped working, and since the format is so non-specific, it is not possible be sure as far as we can tell.
These images were indexed by looking for standard transaction output script hashes that contain JPEG or PNG images immediately on the first payload byte based on file signature bytes and indexed/easily downloaded at github.com/cirosantilli/bitcoin-inscription-indexer#image-indexing-and-download.

This ad highlights one of the claimed potential advantages of Bitcoin: cheaper/faster cross border transactions.
This inscription is highlighted at Data Insertion in Bitcoin's Blockchain by Andrew Sward, Vecna OP_0 and Forrest Stonedahl. Finding Gzips with binwalk is hard because the file signature is only 2 bytes long (1F 8B), so there are lots of false positives.

western-union-bitcoin-spoof.jpg.gz: decompression OK, trailing garbage ignored
but we were not able to fix that: removing bytes at the end goes straight from "trailing garbage" to "incomplete file" after a certain byte.

The image data is cut in half. This makes the image an invalid JPEG, but ImageMagick is able to recover and convert to a valid image which is what we show here to make it portable to more browsers. The raw invalid image is present at: raw.githubusercontent.com/cirosantilli/media/master/bitcoin-inscription-indexer/data/bin/b673c7d0c62cce8315ad6cc63a2c8ca8169bf73432435760b808735e1a7fe0e2.jpg, but it can also be generally viewed by most viewers.

The first block is:
Hello world! Return blob protocol v1: MAGIC = 0x62, PACKAGE = uint16, SEQUENCE = uint16, PAYLOAD = up to
which then gets repeated, probably an error, but now with the sentence completed:
Hello world! Return blob protocol v1: MAGIC = 0x62, PACKAGE = uint16, SEQUENCE = uint16, PAYLOAD = up to 35 bytes
This therefore gives us the name of the protocol as "return blob protocol". We also understand that the 0x62 was aconfiguration parameter.
ffd8ffe1 marks the start of the JPEG.
If the rest of the image were inscribed somewhere random in the blockchain, we'd expect to find the string 6200010089 containing the netxt data chunck on a nearby block, but bgrep did not find it, so perhaps the data just isn't there.
The last tx of the daisy is 43b182065ab2c7d1908ec3cee756d9f626c1e4bd1efa17a7c3993433b653d499 which is followed by 9e6838a3545bd59a708d0c177d6840c7d82b8ac6220138ca3d8133a1376405aa which does not contain any data.

A white man and a Chinese woman wearing Chinese traditional dressess holding hands, presumably a token from their wedding. A Chinese poem is visible next to them, with four vertical setences made up of 7 characters each, to be read from right to left. This is a classic Classical Chinese poetry form known as qijue.
A photo of a snowy mountain is shown in the background, fitting the theme of the poem. It looks like an European mountain, possibly Mont Blanc? TODO identify. Perhaps a reference to the nationality of the husband.
TODO transcribe the Chinese text, cursive grass script + traditional characters + ultra-low res put this beyond Ciro Santilli's capabilities/patience ratio. Ciro Santilli's wife's transcribed gave the first column as:

and no Google hits, so maybe an original poem? What a hero. TODO transcribe the rest.

Hand written contract
.
Wedding contract written in Czech. Transcription and translation by Petr Kadlec:
Svým podpisem pod tímto textem potvrzuji, že Daniela Dudysová a Pavel Urbaczka v mé přítomnosti dne 20.8.2016 v Ropici projevili vůli uzavřít spolu manželství, přičemž ani jeden z těchto projevů se mi nejevil jako nesvobodný, nikoliv vážný, nesrozumitelný, omylný nebo uzavřený v tísni.
Translation:
With my signature under this text, I confirm Daniela Dudysová and Pavel Urbaczka have, in my presence on 2016-08-20 in Ropice, expressed the will to enter marriage, whereas neither of their expressions seemed to me to be non-free, not serious, in error, or under distress.
Signatures:
Tereza (unreadable) Hana (unreadable) Jakub (unreadable) Radim Kozub (unreadable) (unreadable) Lenka (unreadable)
Petr also conjectures that Jakub may refer to Jakub Olšina from Blockchain Legal. Figure 23. "Wedding on grass" on the same block contains a image of a wedding, presumably the same of the contract. The photo of the man might be the same person as www.linkedin.com/in/olsinajakub/, but a bit younger.

The file contains the following text embedded into it:
Danila a Pavel se právě vzali!
which is Czech for:
Danila and Pavel just got married!
So it is a followup to Figure 22. "Hand written contract".

The file contains the following Spanish poem, whch confirms that their Spanish looking faces are actually Spanish, perhaps they are at the Pyrenees:
Entre tus brazos y los míos
no hay espacio, tan juntitos
estamos que los pensamientos
son uno.
A veces somos casi dos desconocidos,
raros tan raros cómo distintos,
pero nos engañamos, tú lo sabes yo lo sé,
en realidad somos muy dentro
la misma verdad.
Escondidos en tus ojitos
duermen mis sueños más hermosos,
cuándo los abres frente a mi
se despiertan alegres y rumbosos.
Which translates as:
Between your arms and mine
there is no space, so close together
we are the thoughts
They are one.
Sometimes we are almost two strangers,
strange as strange as they are different,
but we deceive ourselves, you know it, I know it,
actually we are very inside
the same truth.
Hidden in your eyes
my most beautiful dreams sleep,
when do you open them in front of me
They wake up happy and cheerful.
Not easy Google hits so possibly novel.

This P2FMS has the peculiarity that each payload constant is preceded by a 04 byte which must be thrown away, we've decoded it manually with:

Genesis block message Updated +Created
Inscription added by Satoshi Nakamoto on the Genesis block containing:
The Times 03/Jan/2009 Chancellor on brink of second bailout for banks
which is a reference to: www.thetimes.co.uk/article/chancellor-alistair-darling-on-brink-of-second-bailout-for-banks-n9l382mn62h wihch is fully titled:
Chancellor Alistair Darling on brink of second bailout for banks
The "Alistair" was slikely removed due to limited payload concerns.
Through the newspaper reference, the message proves a minimal starting date for the first mine.
And it hints that one of Bitcoin's motivation was the financial crisis of 2007-2008, where banks were given bailouts by the government to not go under, which many people opposed as the crisis was their own fault in the first place. A notable related stab is taken at Len Sassaman tribute.
We can extract the image from the blockchain ourselves by starting from: blockchain.info/block-height/0?format=json.
From that page we manually extract the hash 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f and then:
wget -O 0.hex https://blockchain.info/block/000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f?format=hex
xxd -p -r 0.hex
and that does contain the famous genesis block string:
EThe Times 03/Jan/2009 Chancellor on brink of second bailout for banks
The JSON clarifies that the data is encoded in the script field of the transaction input:
{
      {
         "script":"04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73"
The extra E (0x45 in ASCII) in EThe Times is just extra noise required by the script, we can break things up as:
04ffff001d0104 45 5468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73
where:
  • 54 is T
  • the 04ffff001d0104 part just doesn't show up on the terminal because it is not made of any printable characters.
The initial 04 is OP_RETURN.
TODO what is actual the meaning of the ffff001d010445 part? @defango twitter.com/defango/status/1642750851134652417 comments:
04ffff001d0104 is a hexadecimal string. It is commonly used in the Bitcoin network as a part of the mining process. Specifically, it is used as the target value for a block to be considered valid by the Bitcoin network.
This value represents the level of difficulty required for a miner to generate a block that meets the network's criteria. The first four bytes, 04ffff, represent the maximum possible target value. The next three bytes, 001d01, represent the current difficulty level
while the final byte, 04, is a padding byte. In summary, this value sets the difficulty level for mining a new block in the Bitcoin network.
TODO the output of the transaction has a jumbled script, likely just a regular output to get things going, can't be arbitrary like input.

Ciro Santilli envies this guy a bit. He dumps his brain more or less full time on his highly customized static website partly due to early Bitcoin investments gwern.net/me says:
I am a freelance American writer & researcher. (To make ends meet, I have a Patreon, benefit from Bitcoin appreciation thanks to some old coins, and live frugally.)
Also unsurprisingly he likes Haskell:
I mostly contribute to projects in Haskell, my favorite language
Ciro Santilli considers Gwern Ciro Santilli's e-soulmates due to his interest in "dark web things" like Bitcoin and Silk Road, his immense writing output in encyclopedic book-sized articles on a static website, and his desire to live frugally and just research and write all day. Ah, if only Ciro had some old coins!!!
This is likely a pseudonym, his real name not being publicly unknown, e.g. at news.ycombinator.com/item?id=5659278:
Why do you choose relative anonymity?
For the reasons I've said in the past. To which I can add personal safety: my Silk Road page is a bit questionable legally, and we all know that there are ways to exploit knowledge of one's True Name and address (even if, as far as I know, I have no enemies willing to resort to, say, 'swatting' me) - one group of stalkers called up a college they thought I worked at to see if they could get me fired or otherwise ruin my day.
