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.

Code 1. .
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?".
Figure 3.
YellowRobot.jpg
. Source.
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.

He put it there after working a bit on Section "How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it" :-) And he would love to document more experiments like that one Section "Videos of all key physics experiments", but opportunities are extremely rare.
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!

Adolfo Amidei Updated +Created
This dude mentored Enrico Fermi in high school. Ciro Santilli added some info to Fermi's Wikipedia page at: en.wikipedia.org/w/index.php?title=Enrico_Fermi&type=revision&diff=1050919447&oldid=1049187703 from Enrico Fermi: physicist by Emilio Segrè (1970):
In 1914, Fermi, who used to often meet with his father in front of the office after work, met a colleague of his father called Adolfo Amidei, who would walk part of the way home with Alberto [Enrico's father]. Enrico had learned that Adolfo was interested in mathematics and physics and took the opportunity to ask Adolfo a question about geometry. Adolfo understood that the young Fermi was referring to projective geometry and then proceeded to give him a book on the subject written by Theodor Reye. Two months later, Fermi returned the book, having solved all the problems proposed at the end of the book, some of which Adolfo considered difficult. Upon verifying this, Adolfo felt that Fermi was "a prodigy, at least with respect to geometry", and further mentored the boy, providing him with more books on physics and mathematics. Adolfo noted that Fermi had a very good memory and thus could return the books after having read them because he could remember their content very well.
Ciro Santilli really likes guys like this. Given that he does not have the right genetics, conditions and temperance for scientific greatness in this lifetime, he dreams of one day finding his own Fermi instead.
Cirism Updated +Created
Welcome to the wonderful world of Cirism!
Followers of Cirism call themselves Cirists, and their primary goal in life is to obtain Cirocoins.
Enlightened Cirists donate money to the cause at: Section "Sponsor Ciro Santilli's work on OurBigBook.com". It is totally optional of course, your soul will just be eternally damned if you don't.
Ciro Santilli once proclaimed:

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!
1000 Monero donation Updated +Created
On 2024-03-18, Ciro Santilli received an anonymous 1000 Monero donation (worth ~126k USD at the time) to his self-custody wallet, which pushed him over his public plea for 100k USD goal to quit his job for one year.
The transaction ID was 5c6af4df39021f3a4a053ef169c9b397e6d6bf6c7e557d3f08e4e1675d7d3eed to self hist custody wallet with address 47kzoCeRMTohJhADejtsGmGimvQKzNsuST7u2aVhAD1VX5WDbh3v1FPUoJoTK3NTJVUgAM3dWCqC4Tmp9KSQaJi6GGYWgYn. This is a roof generated by his Monero wallet: InProofV2AVFBmFhofH4GoG5NsaDutkdNWRTaEhuFgHpHTkpprRmuZ54B8FdUwFp71gqfp2jJpDUrhB3GCzZ2p8CNbh2TW1Z88ShmYWEwtkZFLccEMw9PhH3vWcMVo9mKaRsH3WgJXqq9.
Since this donation is so huge, it deserves some comments and a bit of a retrospective. The path to this donation has been an interactive one, and it is described below.
After starting the OurBigBook Project, Ciro started the sponsor Ciro Santilli's work on OurBigBook.com page on cirosantilli.com and setup some donation methods to help support the project, and possibly try to capitalize a bit on Ciro Santilli's Stack Overflow contributions.
His sponsors are absolutely crazy amazing people, but Ciro simply could attract a large enough amount of small sponsors to reach life changing amounts under those circumstances. This is partly due to Video "And I am not and never have been 'familiar' scene from The Big Short (2015)".
As such, Ciro came to realize more and more that the best approach would be to reach out to a smaller number of rich people, given that the things he works on niche, but may appeal to a particularly wealthy tranche of the population: STEM people. Other experiences and ideas that contribute to this realization are:
  • the creation of the OurBigBook Fellowship, which as of writing consisted of a single donation. During this exercise, Ciro Santilli gave about 2k USD to help a promising Brazilian student. In doing so, he understood a lot about what goes on inside a "rich person's" head when considering a donation
    • it is hard to decide who to donate to and find those people. In part because as soon as you create a public donation system with an application process, people will game the fuck out of it. Perhaps the Lost Horse LLC approach of "they find you" is the best?
    • it is basically impossible to donate more than 1% of your net worth if you have a family. Even 1% you may be discouraged about. Perhaps with reason due to previous bad donations they have made.
  • the increasing wealth inequality of this world, perhaps one of the greatest problems we now face
Then, whenever a larger donation would come through and surprise Ciro, he would improve his sponsor page statements. First a private 150 USD by an awesome sponsor. Then the 2023-09 ~810$ Bitcoin one. Finally came the 2023-11-20 100 Monero one. And it was that one that pushed Ciro to start his "100k USD = 1 year campaign".
Finally on 2024-03-13, Ciro received an anonymous 10 Monero donation to self-custody wallet. He had clearly stated that one should make a test donation to that wallet before the big one, so 10 Monero felt like it could be the test one. Ciro communicated the reception at: mastodon.social/@cirosantilli/112112988286298258 and twitter.com/cirosantilli/status/1769464788009066710:
I cashed out 10 XMR on @AgoraDesk for ~1,375 USD, and kept some change in the wallet for fun. This donation confirms that my self-hosted wallet and cash-out work just fine, so feel free to drop those millions whenever you want Mr. Anon :-)
Over the next few days, Ciro checked his wallet more often than his previously self imposed once a weekend max, and as expected, he found the big one on a slightly despaired around midnight sleepless night (partly due to parenthood). He was feeling particularly bored and a bit sad with his work life that night. And there it was. 1000 Monero on the wallet. Needless to say, not much sleep was done on that evening!!!

The following days were also tense, with Ciro having a trial by fire on selling large amounts of Monero on the UK, which is not trivial as it had been banned from all major exchanges. But he managed. Further notes on that at: www.reddit.com/r/Monero/comments/17arz9f/converting_xmr_to_gbp_in_the_uk/. Ciro also decided to keep about 200 Monero around just for fun as a crazy moonshot.
Another major factor likely Ciro having published his article: Section "Cool data embedded in the Bitcoin blockchain" in 2019. This is something he wrote entirely for fun during an intense 3 week side-time binge in 2019, though some large updates were made later on. It was this article that likely some crypto-dude attention to Ciro Santilli's profile. As of 2024, there is said to be about 20 crypto billionaires, so perhaps there are about 2000 crypto 10 millionaires[ref], which is the minimum net worth for a donation of 100k USD to be feasible (1% mark). And perhaps a reasonable number of them are just nerds who got rich, and want to improve the world. There are two lessons from this:
  • follow your instincts, always. If something seems mega fun and quick, do it!
  • making money from a few rich people (or entities like organizations) is easier than working for a bunch of poor people, because you have to convince less people. If you reach many poor people however, things are much more stable as you can lose a few customers and still be fine
Another factor in the donation, Ciro Santilli believes, is that many rich people thing that education is bullshit. Many successful people are neurodiverse and as such, it is only natural that a large number of rich people want to improve our educational system, which tends to be the very epitome of "boring and average normality" which Ciro Santilli so much detests. This can also be seen in people such as:
Amazing reactions from the Monero Reddit community: www.reddit.com/r/Monero/comments/1brryao/ciro_santilli_received_a_1000_xmr_donation_to/
  • geonic_ comments:
    Reaction video is fake. Very bad acting.
  • Inaeipathy comments:
    Well, anyways, I would be very unsurprised if this 1000 XMR was sent to him by himself for... reasons.
  • -TrustyDwarf- comments:
    Anyone mind to explain wtf this ugly piece of webpage reminding me of geocities from the 90s is about? I'd read it myself but I can't because it already gave me eye cancer.
  • rbrunner7 comments:
    It's all quite strange. Never mind the 90s design, people built good websites already back then with the tools at hand, but even their "About" isn't very clear. If you need 5 minutes to be reasonably sure what it is all about they are still doing it wrong.
These people have some serious trust issues!!! Perhaps not surprising from a privacy coin community. Ciro's Twitter post: twitter.com/cirosantilli/status/1775961945193017790
