Ciro Santilli 37 Created 2024-10-23 Updated 2025-07-16On Friday 18th October 2024, Ciro Santilli received a call from Barclays asking where some of the money in his Barclays account came from and went to, obviously linked to the Monero donation and sale.
The following day, the 19th, a "explain your income in 30 days or you'll lose you account" letter arrived, dated from the 8th of October. This had been available on the online documents, but Ciro did not get an email for it so he was unaware.
The following Tuesday, the 22nd, Ciro noticed that all payments from his card were being declined, and upon calling Barclays they said that this was for pending regulatory issues. His account had been frozen.
The following Tuesday, 29th of November, Ciro noticed that a regular payment had gone through. He then tested his card and it was working again, so at some point the account had been unfrozen.
Part of me wants the donor to give me his real identity and sort this out. It would likely be better for the OurBigBook Project. But the other part of me wants to test the British monetary system. Fun and stressful times.
The chaotic nature of Barclays' Know your customer is apparent:
- they took 6 months to flag anything
- once it was finally flaggedAlso, they freeze accounts of people who are still obviously in the country at their home address and making regular purchases locally as before. Not exactly how a criminal would act?
- their communication is a mess:
- the letter was messy, with unclear list of transactions at some points and several typos
- there was no clear notice that the account was frozen or unfrozen. While there can be a rationale for not giving notice before the freeze to prevent criminals from fleeing, once you freeze a regular account user will find it out mighty fast, so there is no point in not notifying them about it
- they block the account days after the online document had been available (which unfortunately Ciro did not see due to lack of email notification), but before you've had the time to reply. This achieves the worst of both worlds both worlds by:
- their communication is a mess:
It is also slightly fun, but not surprising, to see the AgoraDesk buyers refuse to give any contact besides their public Telegram, not even email. I'm not sure that Barclays does Telegram! Not super important though because ultimately the initial Monero donation is anonymous. Shame I started on AgoraDesk before finding out about cryptocurrency swappers such as SimpleSwap.
De-banking is apparently a widespread issue in the UK: www.uktech.news/fintech/revolut-good-reason-debank-20240909: e.g. www.uktech.news/fintech/revolut-good-reason-debank-20240909 notably mentions a well known base by, God forgive me, Nigel Farage.

Symmetric encryption is a type of encryption where you use a password (also known as a "key") to encrypt your data, and then the same password to decrypt the data.
For example, this is the type of encryption that is used for encrypting the data in our smartphones and laptops with disk encryption.
This way, if your laptop gets stolen, the thief is not able to see your private photos without knowing your password, even though they are able to read every byte of your disk.
The downside is that that you have to type your password every time you want to login. This leads people to want to use shorter passwords, which in turn are more prone to password cracking.
The other main type of encryption is public-key cryptography.
The advantage of public-key cryptography is that it allows you to send secret messages to other people even an the attacker is able to capture the encrypted messages. This is for example what you want to do when sending a personal message to a friend over the Internet. Such encryption is especially crucial when using wireless communication such as Wi-Fi, where anyone nearby can capture the signals you send and receive, and would be able to read all your data if it weren't encrypted.
Easily sending encrypted messages over the Internet is not possible with symmetric encryption because for your friend to decrypt the message in that system, you'd need to send them the password, which the attacker would also be able to eavesdrop and then decrypt the message that follows using it. The problem of sharing a password with another person online is called key exchange.
Advanced Encryption Standard (AES) is one of the most popular families of symmetric encryption algorithms.
OpenSSL is a popular open source implementation of symmetric and public-key cryptography. A simple example of using OpenSSL for symmetric encryption from the command-line is:This asks for a password, which we set as contains:Then to decrypt:once again asks for your password and given the correct password produces a file This was tested on Ubuntu 24.04, OpenSSL 3.0.13. See also: How to use OpenSSL to encrypt/decrypt files? on Stack Overflow.
echo 'Hello World!' > message.txt
openssl aes-256-cbc -a -salt -pbkdf2 -in message.txt -out message.txt.encasdfqwer, and then produces a file message.txt.enc containing garbled text such that:hd message.txt.enc00000000 55 32 46 73 64 47 56 6b 58 31 38 58 48 65 2f 30 |U2FsdGVkX18XHe/0|

00000020 4e 37 6d 52 2f 73 6d 4d 62 64 30 3d 0a |N7mR/smMbd0=.|
0000002dopenssl aes-256-cbc -d -a -pbkdf2 -in message.txt.enc -out message.new.txtmessage.new.txt containing the original message:Hello World!There is no provably secure symmetric-key algorithm besides the one-time pad, which has the serious drawback of requiring the key to be as long as the message. This means that we believe that most encryption algorithms are secure because it is a hugely valuable target and no one has managed to crack them yet. But we don't have a mathematical proof that they are actually secure, so they could in theory be broken by new algorithms one day.

Intro/docs: www.jonmsterling.com/jms-005P.xml. It is very hard to find information in that system however, largely because they don't seem to have a proper recursive cross file table of contents.
This is the project with the closest philosophy to OurBigBook that Ciro Santilli has ever found. It just tends to be even more idealistic than, OurBigBook in general, which is insane!
"Docs" at: www.jonmsterling.com/foreign-forester-jms-005P.xml Sample repo at: github.com/jonsterling/forest but all parts of interest are in submodules on the authors private Git server.
Example:
- sample source file: git.sr.ht/~jonsterling/public-trees/tree/2356f52303c588fadc2136ffaa168e9e5fbe346c/item/jms-005P.tree

They have
\Include like OurBigBook, nice: www.jonmsterling.com/jms-007L.xml, but OMG that name \transclude{xxx-NNNN}!! It seems to be possible to have human readable IDs too if you want: www.jonmsterling.com/foreign-forester-armaëlguéneau.xml is under trees/public/roladex/armaëlguéneau.tree.Headers have open/close:OurBigBook considered this, but went with
\subtree[jms-00YG]{}parent= instead finally to avoid huge lists of close parenthesis at the end of deep nodes.One really cool thing is that the headers render internal links as clickable, which brings it all closer to the "knowledge base as a formal ontology" approach.
The markup has relatively few insane constructs, notably you need explicit open paragraphs everywhere
\p{}?! OMG, too idealistic, not enough pragmatism. There are however a few insane constructs:The markup is documented at: www.jonmsterling.com/foreign-forester-jms-007N.xml
Jon has some very good theory of personal knowledge base, rationalizing several points that Ciro Santilli had in his mind but hadn't fully put into words, which is quite cool.
OCaml dependency is not so bad, but it relies on actually LaTeX for maths, which is bad. Maybe using JavaScript for OurBigBook wasn't such a bad choice after all, KaTeX just works.
Viewing the generated output HTML directly requires
security.fileuri.strict_origin_policy which is sad, but using a local server solves it. So it appears to actually pull pieces together with JavaScript? Also output files have .xml extension, the idealism! They are reconsidering that though: www.jonmsterling.com/foreign-forester-jms-005P.xml#tree-8720.The Ctrl+K article dropdown search navigation is quite cool.
\rel and \meta allows for arbitrary ontologies between nodes as semantic triples. But they suffer from one fatal flaw: the relations are headers in themselves. We often want to explain why a relation is true, give intuition to it, and refer to it from other nodes. This is obviously how the brain works: relations are nodes just like objects.They do appear to be putting full trees on every toplevel regardless how deep and with JavaScript turned off e.g.:
which is cool but will take lots of storage. In OurBigBook Ciro Santilli only does that on OurBigBook Web where each page can be dynamically generated.
