Ciro Santilli 37 Updated 2025-07-16
Ciro Santilli 37 Updated 2025-07-16These can be viewed at bitcoinstrings.com/blk00052.txt and are mostly commented on the "Wikileaks cablegate data" section of Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014).
Soon after block 229991 uploaded the Satoshi uploader, several interesting files were added to the blockchain using the uploader, and notably some containing content that might be illegal in certain countries, as a test to see if this type of content would make the Bitcoin blockchain illegal or not:
- tx 08654f9dc9d673b3527b48ad06ab1b199ad47b61fd54033af30c2ee975c588bd block 229999 contains a leaked private key and a link to: threatpost.com/en_us/blogs/ami-firmware-source-codAe-private-key-leaked-040513

cablegate-201012041811.7z. As mentioned in Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014), it has an ASCII list of several other transactions, which presumably when downloaded with the Satoshi uploader can concatenated lead to the full 7z file. Also as mentioned by Ken, it is infinitely easier for the average user to just access the cables directly on WikiLeaks :-) The data is preceded by the message:sSEXWikileaks Cablegate Backup cablegate-201012041811.7z Download the following transactions with Satoshi Nakamoto's download tool which can be found in transaction 6c53cd987119ef797d5adccd76241247988a0a5ef783572a9972e7371c5fb0cc Free speech and free enterprise! Thank you Satoshi! - tx dde7cd8e8f073a525c16c5ee4e4a254f847b7ad6babef257231813166fbef551 block 230229 and tx 4a0088a249e9099d205fb4760c28275d4b8965ac9fd56f5ddf6771cdb0d94f38 block 230231 contain indexes of pages from The Hidden Wiki. These can be viewed at: bitcoinstrings.com/blk00052.txt. Not reproduced here because we are cowards.
So basically, this was the first obviously illegal block attempt.
None of this content is particularly eye-popping for Ciro Santilli's slightly crazy freedom of speech standards, and as of 2021, the Bitcoin blockchain likely hasn't become illegal anywhere yet due to freedom of speech concerns.
Furthermore, it is likely much easier to find much worse illegal content by browsing any uncensored Onion service search engine for 2 minutes.
Ciro Santilli estimates that perhaps the uploader didn't upload child pornography, which is basically the apex of illegality of this era, because they were afraid that their identities would one day be found.

Their main techniques seem to be:and:mkdir binout for file in blk*dat; do echo "$file"; binwalk --dd='.*' "$file" -C binout/. --log=binout/"$file""res.txt"; donewhich seem promising.mkdir subfileout for file in blk*dat; do mkdir subfileout/"$file"; done for file in blk*dat; do echo "$file"; hachoir-subfile --category=image,video,audio,container,archive,misc "$file" subfileout/"$file" > subfileout/"$file""subfile.txt"; doneTODO how to they automatically map back to transaction IDs? There is a line "Script to add the TX ID to each file." Our attempts: Section "Get transaction id from position in dat file"

As the quintessential fabless fab, there is on thing TSMC can never ever do: sell their own design! It must forever remain a fab-only company, that will never compete with its customers. This is highlighted e.g. at youtu.be/TRZqE6H-dww?t=936 from Video "How Nvidia Won Graphics Cards by Asianometry (2021)".
How Taiwan Created TSMC by Asianometry (2020)
Source. Some points:- UCM failed because it focused too much on the internal market, and was shielded from external competition, so it didn't become world leading
- one of TSMC's great advances was the fabless business model approach.
- they managed to do large technology transfers from the West to kickstart things off
- one of their main victories was investing early in CMOS, before it became huge, and winning that market
You need a secondary password that when used leads to an empty inbox with a setting set where message are deleted after 2 days.
This way, if the attacker sends a test email, it will still show up, but being empty is also plausible.

Predicted by the Dirac equation.
Can be easily seen from the solution of Equation "Expanded Dirac equation in Planck units" when the particle is at rest as shown at Video "Quantum Mechanics 12b - Dirac Equation II by ViaScience (2015)".
A relativistic version of the Schrödinger equation.
Correctly describes spin 0 particles.
The most memorable version of the equation can be written as shown at Section "Klein-Gordon equation in Einstein notation" with Einstein notation and Planck units:
Has some issues which are solved by the Dirac equation:
- it has a second time derivative of the wave function. Therefore, to solve it we must specify not only the initial value of the wave equation, but also the derivative of the wave equation,As mentioned at Advanced quantum mechanics by Freeman Dyson (1951) and further clarified at: physics.stackexchange.com/questions/340023/cant-the-negative-probabilities-of-klein-gordon-equation-be-avoided, this would lead to negative probabilities.
- the modulus of the wave function is not constant and therefore not always one, and therefore cannot be interpreted as a probability density anymore
- since we are working with the square of the energy, we have both positive and negative value solutions. This is also a features of the Dirac equation however.
