Interesting dude.
By the rich founder of Mt. Gox and Ripple, Jed McCaleb.
Obelisk is the Artificial General Intelligence laboratory at Astera. We are focused on the following problems: How does an agent continuously adapt to a changing environment and incorporate new information? In a complicated stochastic environment with sparse rewards, how does an agent associate rewards with the correct set of actions that led to those rewards? How does higher level planning arise?
Is it mega fast? Nope
Does it work? Yup.
"P2FMS" terminology mentioned e.g. at: Data Insertion in Bitcoin's Blockchain by Andrew Sward, Vecna OP_0 and Forrest Stonedahl.
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.

Cool data embedded in the Bitcoin blockchain Ordinal ruleset inscription by Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01
Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01Ordinals are inscriptions created with the protocol described at: docs.ordinals.com/inscriptions.html The protocol was designed by developer Casey Rodarmor, and shares a few similarities with the AtomSea & EMBII protocol.
The protocol also includes a way to have ownership over inscriptions, effectively creating an NFT system on top of the bitcoin blockchain. AtomSea & EMBII also already had such a system however. In either case, Ciro Santilli couldn't give less of a fuck about who owns some random publicly viewable digital asset.
For whatever reason, orinals became extremelly popular compared to the AtomSea & EMBII format, leading to millions os inscriptions, and 10k+ images as of block 830k. They also started to take up a substatial portion of the available block space.
This in turn led to a lot of child porn rediscussion, and people linking back to this page to view earlier inscriptions: incoming links.
Unfortunately, unlike AtomSea & EMBII and even cryptograffiti.info uploads, most ordinals are designed to be just souless bulk collectibles, as with as much artistic merit as any random collectible card set or postage stamps you may find at a newpaper stall. To make things worse many of them are likely algorithmically generated. Eternal September had truly arrived to the Bitcoin blockchain. As a result, machine learning would be almost essential in order to find interesting uploads amidst such bulk.

. This is the first ordinal ruleset inscription: ordinals.com/inscription/6fb976ab49dcec017f1e201e84395983204ae1a7c2abf7ced0a85d692e442799i0. It was made on block 767430 (2022-12-14).The
i0 at the end of the URL above means "inscription 0". This is because a single transaction can have multiple inscriptions.
The ordinals also started taking up large portions of the Bitcoin blockchain:

Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01 Sponsor Ciro Santilli's work on OurBigBook.com 1000 Monero donation by Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01
Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01On 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:
- Michael J. Saylor and his Saylor Academy
- Peter Thiel and his Thiel Fellowship

Amazing reactions from the Monero Reddit community: www.reddit.com/r/Monero/comments/1brryao/ciro_santilli_received_a_1000_xmr_donation_to/These people have some serious trust issues!!! Perhaps not surprising from a privacy coin community. Ciro's Twitter post: twitter.com/cirosantilli/status/1775961945193017790

Sponsor Ciro Santilli's work on OurBigBook.com 1000 Monero donation Anonymity of the donation by Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01
Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01The first sensation Ciro Santilli got was as if God himself had come down from heaven to toy with an unsuspecting human being. God running an experiment. Or perhaps an AGI that had already secretly taken over. Not very different.
Like with God, this was the answer to Ciro's prayers on Twitter. A one way conversation that leaves you uncertain of the details.
Whichever the case, Ciro is going to put on the best show he possibly can for your money, documenting every step along the way in usual fashion!
Ciro ran this over and over in his head, and the only big risk of anonymity is that if this money is ever proven to be from the proceeds of crime, he would have to give it back to the government and "lose one year's salary he would have otherwise gained".
However, that worst case scenario is not bad enough. If anything, it was a great excuse to quit his job for his family and wife is already worth it. Ciro could do it and survive, though situation would deteriorate slowly. But he was a coward previously.
Ciro does however feel that there is good chance that it is legitimate.
Ciro Santilli's Stack Overflow contributions are exceptional, he's amazing right! He deserves this! Of course, there is danger in this rationale which scammers could exploit. But bro, if scammers are going to send 100k USD to me, then please continue to do so!
Also which criminal would be stupid enough to donate proceeds of crime to a highly public person who is going to clearly announce it?
Just be warned, if you come with a baseball bat trying to get the money back by force, I will call the police immediately and by God you will not get it!!
Given this, Ciro just keeps thinking about the likely profile of the donor:
But the "why anonymous if not criminal" question remains. Generally rich people want recognition both for:Two options that come to mind:
- reputation washing
- to make their donation mechanisms higher profile which allows raising more and attracting better candidates and reach greater impact
- rich crypto dude that doesn't want thieves to know he is rich
- more public rich person that doesn't want association with Ciro Santilli's naughty projects, notably Ciro Santilli's campaign for freedom of speech in China, but perhaps also CIA 2010 covert communication websites, which could hurt business.
- crazy rich person with a philosophy of "if they knew who I was it might interfere with what they do". AKA a God.
