Cool data embedded in the Bitcoin blockchain / Raw images Updated 2025-07-16
View more
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.
This embedding uses a novel more specialiezd protocol on top of a raw daisy chain Bitcoin inscription.
The daisy actually starts at f49e79889b34d355fa8a02f13b9db4ed69c067f975e25339737ef10e4b993d7a and data is encoded as follows:

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.

Chinese wedding
.
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:
丹珍默然藏山中
A scarlet gemstone hides quietly in the midst of the mountains.
and no Google hits, so maybe an original poem? What a hero. TODO transcribe the rest.
The image file contains the English transalation of the Chinese poem embeded into it:
A scarlet gemstone hides quietly in the midst of the mountains.
Its beauty softly enters the wanderer's dreams.
Fame and fortune become like drifting clouds
But the gem endures like the constellations above.

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 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.

Cryogenic electron microscopy Updated 2025-07-16

This technique has managed to determine protein 3D structures for proteins that people were not able to crystallize for X-ray crystallography.
It is said however that cryoEM is even fiddlier than X-ray crystallography, so it is mostly attempted if crystallization attempts fail.
By looking at Figure 1. "A cryoEM image", you can easily understand the basics of cryoEM.
We just put a gazillion copies of our molecule of interest in a solution, and then image all of them in the frozen water.
Each one of them appears in the image in a random rotated view, so given enough of those point of view images, we can deduce the entire 3D structure of the molecule.
Ciro Santilli once watched a talk by Richard Henderson about cryoEM circa 2020, where he mentioned that he witnessed some students in the 1980's going to Germany, and coming into contact with early cryoEM. And when they came back, they just told their principal investigator: "I'm going to drop my PhD theme and focus exclusively on cryoEM". That's how hot the cryo thing was! So cool.

Csound Updated 2025-07-16

XML file format (but with 99% of the action of interest in a domain-specific language on the CsInstruments and CsScore elements) that can be played and the reference implementation. Offers complex effects out-of-box apparently.
Allows you to easily define instruments with seemingly arbitrary mathematical functions, and then use them to play notes at given time intervals.
The instrument functions can be parametrized, and each note played can have different parameters.
The instrument definition actually defines a block diagram graph, much like a hardware synthesizer would.
Csound is so not-bloated that it contains an UI system. And it includes an interactive virtual MIDI keyboard that interacts with parameter knobs: www.csounds.com/manual/html/MidiTop.html
But hey, it's fun. And like any other good domain-specific language, debugging it is barbaric of course.
If only it had been written in Python... the array manipulation boilerplate would be likely perfect for NumPy, and this would have been exactly what Ciro Santilli wanted!
CSound states that one of its design goals is backward compatibility, and it shows. Some of the stuff is utterly arcane, e.g. you have to remember what GEN10, GEN11, etc. mean instead of having named enums.
It just worked on Ubuntu 20.04 no questions asked:
sudo apt install csound
git clone https://github.com/csound/csound
cd csound
git checkout 92409ecce053d707360a5794f5f4f6bf5ebf5d24
csound examples/xanadu.csd
which runs this file: github.com/csound/csound/blob/92409ecce053d707360a5794f5f4f6bf5ebf5d24/examples/xanadu.csd and this plays a relly cool sound demo:

TODO find the most amazing set of songs made with it on GitHub? Some examples:
Documentation-wise, it's a bit lacking. The only dude who can explain it really well, Dr Richard Boulanger, made the "The Csound Book" closed source, so, congrats, this will forever hurt the popularity of Csound.

Daisy chain Bitcoin inscription Updated 2025-07-16
View more
This is a term invented by Ciro Santilli, and refers to a loose set of uncommon Bitcoin inscription methods that involve inscribing one or a small number of payloads per Bitcoin transaction.
These methods are both inefficient and hard to detect and decode, partly because Bitcoin Core does not index spending transactions: bitcoin.stackexchange.com/questions/61794/bitcoin-rpc-how-to-find-the-transaction-that-spends-a-txo. This makes finding them all that more rewarding however.
On the other hand, they do have the advantage of not depending on any block size limits, as their individual transactions are very small.
Inscribing anything large would however take a very long time, as you'd have to wait until the previous payload chunk is confirmed before going to the next one. This alone makes the format impractical perhaps.

David Tong Updated 2025-07-16

A charismatic, perfect-English-accent (Received Pronunciation) physicist from University of Cambridge, specializing in quantum field theory.
He has done several "vulgarization" lectures, some of which could be better called undergrad appetizers rather, a notable example being Video "Quantum Fields: The Real Building Blocks of the Universe by David Tong (2017)" for the prestigious Royal Institution, but remains a hardcore researcher: scholar.google.com/citations?hl=en&user=felFiY4AAAAJ&view_op=list_works&sortby=pubdate. Lots of open access publications BTW, so kudos.
The amount of lecture notes on his website looks really impressive: www.damtp.cam.ac.uk/user/tong/teaching.html, he looks like a good educator.
David has also shown some interest in applications of high energy mathematical ideas to condensed matter, e.g. links between the renormalization group and phase transition phenomena. TODO there was a YouTube video about that, find it and link here.
Ciro Santilli wonders if his family is of East Asian, origin and if he can still speak any east asian languages. "Tong" is of course a transcription of several major Chinese surnames and from looks he could be mixed blood, but as mentioned at www.ancestry.co.uk/name-origin?surname=tong it can also be an English "metonymic occupational name for a maker or user of tongs". After staring at his picture for a while Ciro is going with the maker of tongs theory initially.

Deep tech Updated 2025-07-16
View more
Ciro Santilli is a fan of this late 2010's buzzword.
It basically came about because of the endless stream of useless software startups made since the 2000's by one or two people with no investments with the continued increase in computers and Internet speeds until the great wall was reached.
Deep tech means not one of those. More specifically, it means technologies that require significant investment in expensive materials and laboratory equipment to progress, such as molecular biology technologies and quantum computing.
And it basically comes down to technologies that wrestle with the fundamental laws of physics rather than software data wrangling.
Computers are of course limited by the laws of physics, but those are much hidden by several layers of indirection.
Full visibility, and full control, make computer tasks be tasks that eventually always work out more or less as expected.
The same does not hold true when real Physics is involved.
Physics is brutal.
To start with, you can't even see your system very clearly, and often doing so requires altering its behaviour.
For example, in molecular biology, most great discoveries are made after some new technique is made to be able to observe smaller things.
But you often have to kill your cells to make those observations, which makes it very hard to understand how they work dynamically.
What we would really want would be to track every single protein as it goes about inside the cell. But that is likely an impossible dream.
The same for the brain. If we had observations of every neuron, how long would it take to understand it? Not long, people are really good at reverse engineering things when there is enough information available to do so, see also science is the reverse engineering of nature.
Then, even when you start to see the system, you might have a very hard time controlling it, because it is so fragile. This is basically the case of quantum computing in 2020.
It is for those reasons that deep tech is so exciting.
The next big things will come from deep tech. Failure is always a possibility, and you can't know before you try.
But that's also why its so fun to dare.
Stuff that Ciro Santilli considers "deep tech" as of 2020:

Deletionism on Wikipedia Updated 2025-07-16
View more
Some examples by Ciro Santilli follow.
Of the tutorial-subjectivity type:
Notability constraints, which are are way too strict:
There are even a Wikis that were created to remove notability constraints: Wiki without notability requirements.
For these reasons reason why Ciro basically only contributes images to Wikipedia: because they are either all in or all out, and you can determine which one of them it is. And this allows images to be more attributable, so people can actually see that it was Ciro that created a given amazing image, thus overcoming Wikipedia's lack of reputation system a little bit as well.
Wikipedia is perfect for things like biographies, geography, or history, which have a much more defined and subjective expository order. But when it comes to "tutorials of how to actually do stuff", which is what mathematics and physics are basically about, Wikipedia has a very hard time to go beyond dry definitions which are only useful for people who already half know the stuff. But to learn from zero, newbies need tutorials with intuition and examples.
