Bitcoin CLI client by Ciro Santilli 37 Updated 2025-07-16
On Bitcoin Core snap 26.0, the executable is called bitcoin-core.cli rather than bitcoin-cli.

Blockchain.info by Ciro Santilli 37 Updated 2025-07-16
TODO who owns it? Are they reliable?
This helper dumps a transaction JSON to a binary:
bitcoin-tx-out-scripts() (
    # Dump data contained in out scripts. Remove first 3 last 2 bytes of
    # standard transaction boilerplate.
    h="$1"
    echo curl "https://blockchain.info/tx/${h}?format=json" |
    jq '.out[].script' tmp.json |
    sed 's/"76a914//;s/88ac"//' |
    xxd -r -p > "${h}.bin"
)
Their API limit witout key is 1 query per 10 seconds!!!
Previously called "bitcoin-strings-with-txids" since text was the initial focus, but Ciro Santilli decided to go for the more general name once images became more and more important to the project.
Set of scripts b Ciro Santilli, primarily created while researching Cool data embedded in the Bitcoin blockchain.
BitcoinStrings.com by Ciro Santilli 37 Updated 2025-07-16
bitcoinstrings.com has all strings -n20 strings, we can obtain the whole thing and clean it up a bit with:
wget -O all.html https://bitcoinstrings.com/all
cp all.html all-recode.html
recode html..ascii all-recode.html
awk '!seen[$0]++' all-recode.html > all-uniq.html
awk to skip the gazillion "mined by message" repeats.
A lot of in that website stuff appears to be cut up at the 20 mark. As shown in Force of Will, this is possibly because they didn't use -w in strings -n20, and the text after the newlines was less than 20 characters.
That website can be replicated by downloading the Bitcoin blockchain locally, then:
cd .bitcoin/blocks
for f in blk*.dat; do strings -n20 -w $f | awk '!seen[$0]++' > ${f%.dat}.txt; done
tail +n1 *.txt
Remove most of the binary crap:
head -n-1 *.txt | grep -e '[. ]' | grep -iv 'mined by' | less
Satoshi uploader by Ciro Santilli 37 Updated 2025-07-16
The uploader, and its accompanying downloader, are Python programs stored in the blockchain itself. They are made to upload and download arbitrary data into the blockchain via RPC.
These scripts were notably used for: illegal content of block 229k. The script did not maintain its popularity much after this initial surge up loads, likely all done by the same user: there are very very few uploads done after block 229k with the Satoshi uploader.
Our choice of name as "Satoshi uploader" is copied from A Quantitative Analysis of the Impact of Arbitrary Blockchain Content on Bitcoin by Matzutt et al. (2018) because the scripts are Copyrighted Satoshi Nakamoto on the header comment, although as mentioned at Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) this feels very unlikely to be true.
A more convenient version of those scripts that can download directly from blockchain.info without the need for a full local node can be found at: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/download_tx_consts.py by using the --satoshi option. E.g. with it you can download the uploader script with:
./download_tx_consts.py --satoshi 4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17
mv 4b72a223007eab8a951d43edc171befeabc7b5dca4213770c88e09ba5b936e17.bin uploader.py
The scripts can be found in the blockchain at:
The uploader script uses its own cumbersome data encoding format, which we call the "Satoshi uploader format". The is as follows:
This means that if we want to index certain file types encoded in this format, a good heuristic is to skip the first 9 bytes (4 size, 4 CRC, 1 OP_1) and look for file signatures.
Let's try out the downloader to download itself. First you have to be running a Bitcoin Core server locally. Then, supposing .bitcon/bitoin.conf containing:
rpcuser=asdf
rpcpassword=qwer
server=1
txindex=1
we run:
git clone git://github.com/jgarzik/python-bitcoinrpc.git
git -C python-bitcoinrpc checkout cdf43b41f982b4f811cd4ebfbc787ab2abf5c94a
wget https://gist.githubusercontent.com/shirriff/64f48fa09a61b56ffcf9/raw/ad1d2e041edc0fb7ef23402e64eeb92c045b5ef7/bitcoin-file-downloader.py
pip install python-bitcoinrpc==1.0
BTCRPCURL=http://asdf:qwer@127.0.0.1:8332 \
  PYTHONPATH="$(pwd)/python-bitcoinrpc:$PYTHONPATH" \
  python3 bitcoin-file-downloader.py \
  6c53cd987119ef797d5adccd76241247988a0a5ef783572a9972e7371c5fb0cc
worked! The source of the downloader script is visible! Note that we had to wait for the sync of the entire blockchain to be fully finished for some reason for that to work.

Monero by Ciro Santilli 37 Updated 2025-07-16
Cryptocurrency with focus on anonymity. Was almost certainly the leading privacy coin since its inception until as of writing in the 2020s.
Ciro Santilli has received and held considerable quantities of Monero, notably 1000 Monero donation. so bias alert.
As mentioned at Section "Are cryptocurrencies useful?", Ciro Santilli believes that anonymity is the most valuable feature that really matters on crypto coins, and therefore if he were to invest in crypto, he would invest in Monero or some other privacy coin.
localmonero.co/knowledge/monero-stealth-addresses?language=en gives an overview of the privacy mechanisms:
  • ring signatures, which hide the true output (sender)
    localmonero.co/knowledge/ring-signatures Gives an overview. Mentions that it is prone to heuristic attacks.
    Uses a system of decoys, that adds 10 fake possible previous outputs as inputs, in addition to the actual input.
    So the network only knows/verifies that one of those 11 previous outputs was used, but it does not know which one.
    It's a bit like having a built-in cryptocurrency tumbler in every transaction.
    TODO so how do you know which previous outputs were spent or not?
  • RingCT which hides the amounts.
  • stealth addresses, which hides who you send to
    This forces receivers to scan try and unlock every single transaction in the chain to see if it is theirs or not.
    The sender therefore can know when the money is spent, but once again, not to whom it is being sent.
Coinbase has actually stayed away from trading it even as of 2019 when Monero was the third largest market capitalization crypto because of fear of regulatory slashback: decrypt.co/36731/heres-why-coinbase-still-hasnt-listed-monero. Although it must be said, the value of privacy crypto is greatly reduced when everyone is trading it on exchanges, which require a passport upload to work.
This is likely a system that uploads text to the blockchain.
One example can be seen on the Marijuana plant.
Messages are uploaded one line per transaction, and thus may be cut up on the blk.txt, and possibly even out of order.
But because each line starts with j( you can generally piece things up regardless.
TODO identify. The first occurrence seems to be in tx e8c61e29c6b829e289f8d0fc95f9eb2eb00c89c85cfa3a9c700b15805451ae6a:

Satoshi Dice by Ciro Santilli 37 Updated 2025-07-16
Claims provably fair. satoshidice.com/fair clarifies what that means: they prove fairness by releasing a hash of the seed before the bets, and the actual seed after the bets.
As mentioned in bitcoin.it, it functions basically as cryptocurrency tumbler in practice.
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"!

My Bitcoin inscription museum by Ciro Santilli
. Source. Introductory video to this article. Edited from Aratu Week 2024 Talk by Ciro Santilli: My Best Random Projects.
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!
Besides ASCII art, the huge majority of images is encoded with the AtomSea & EMBII system/format. All images in that system will be documented in that section.
There are a few dozen ASCII arts in the blockchain.
Almost all of them are copy pastes of stuff present elsewhere, or boring high resolution ones auto-generated from images. But hey, it's still fun to see.

    "The Hashling" presumably refers to a cute fictional crab-like animal that somehow inhabits the alternate reality created Blockchain network's incredible hashrate. Yet another soulless NFT collection would later be created with that name as well: magiceden.io/ordinals/marketplace/hashlings.
    But that is not all! Immediately after the ASCII art encoded as one constant, the remaining constants of the input script except for the last one encode a raw PNG image with a hand drawing of the creature:
    https://raw.githubusercontent.com/cirosantilli/media/master/bitcoin-inscription-indexer/data/bin/a96bda1363e8968f45b05e3c1940ba37b18de53de0157d453ca9bfc44913768c.png
    The last constant is then the only thing that matters and spends the incoming output.
    The ASCII art and image are also inscribed 16 more times on the blockchain: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/hashling. 453c9511ca76361c8c44b4302ce1b5d8d5c98a938b548478ef931baaa7d70e62 also has the image without any ASCII strings.

    Viva la Revolucion! Happy Birthday Santi! Manu, Santi, Demi, Esteban
    and starts a long chain of contiguous transactions that renders Santi's face twice in low resolution. They are encoded one line every two transactions with OP_RETURN:and we've decoded it manually in Vim.
    Both blocks were mined by AntPool, so they weren't mining themselves to enforce ordering. So how is ordering assured? TODO are transactions actually contiguous in the block or are there other transactions interspersed? According to:
    bitcoin-core.cli getblock 00000000000000000baf6e3006fd05a1c5dbca3d430012180f8098cbe8b8ce22
    many of the transactions are contiguous but we haven't checked all of them.

    This image was likely inscribed due to Buffet's general status as an investing God, he did not appear to have strong links to crypto at the tim, he did not appear to have strong links to crypto at the time
    Interestingly, in a twist of fate, in 2018 Buffet would later come to strongly criticize cryptocurrency as "probably rat poison squared": finance.yahoo.com/news/warren-buffett-says-wouldnt-pay-175917403.html.

    The message is encoded with OP_RETURN payloads across multiple transactions, 40 bytes per transaction. They actually managed to upload two almost fully consecutive transaction blocks and in the correct order. Could they be miners?
    Some of the payloads contain newlines, you are just supposed to paste all payloads together to form the image. Our reconstruction here is manual however, lazy to script it properly.

    vaardig regulerend de orde van de dag
    Is in Dutch of course, literally:
    skillfully regulating the order of the day
    Given the date and language, it appears to be a reference to Koningsdag, Dutch national holiday that celebrated the birthday of their King at the time, King Willem-Alexander. Born in 1956, he would have been turning 60 at the time, so a nice round number in 2016 when these birthday candles were inscribed.

    At firs we thought it was some kind of tribute to the Cannes Film Festival, but given the string "Titanium" and the fact that all people mentioned on another section of the art work for advertisement companies, we understand that it is instead almost certainly about the "Cannes Lions International Festival of Creativity", previously "International Advertising Festival", which has a "titanium" prize category, e.g. as mentioned at: www.thedrum.com/news/2018/06/22/cannes-lions-winners-titanium-glass-grand-prix-good-and-more:
    The highly coveted Titanium Lions - created to honor marketing work that doesn't fit neatly into traditional categories
    The part with the at signs '@' which we believe represents the lion is the hardest one and we've perhaps gotten some lines wrong, corrections are welcome.

    The actual code appears to be:
    OPRETURNISMYFRIEND
    a reference to OP_RETURN. It is steganographically encoded diagonally across the skull's eyes. Ciro Santilli only saw this after grepping:
    grep @ data/out/0538.txt
    which made all non @ signs stand out due to the terminal's syntax highligh. This image was uploaded one line per transaction with a few interruptions that we removed manually, and there were was a previous partial attempt a bit before: at tx f8102999c0aaf7681deec383eb8e7946f093e94a116a21e367e9ed6b7c32d1fb so either a failure, or maybe it was intentional to obfuscate things a bit.

    ZN inscription
    .
    This ASCII art had been previously noted by sroose and decoded by brando2131 on Reddit, and was brought to our attention by Bagfoot OP446 on twitter. Ciro Santilli had previously spotted the art, but failed to decode it. "ZENON NETWORK" is inscribed just after the art confiming the meaning of the characters, but it does not appear in our ASCII dumps presumably because the string it is too short and surrounded by non-ASCII.
    Each line is encoded with OP_RETURN, is 38 bytes long, and starts and ends in 6 spaces, leading to 26 non-whitespace characters per line. The lines appear in scambled order and it is unclear if there is any logic in the ordering or if it was just meant as a little puzzle. But given the nearby "ZENON NETWORK" inscription, this decoding is overwhelmingly likely correct.
    The following lines also show up in our ASCII dump:
      ;4Fdzw1k=zzzzzzzzzzzzzzzz;      
      ,vtv3f5aKY0jGQglP9a1AGw==.      
      ;BynQtpeUyWTXKGTrGhdV2Q==;      
      ;tVMd3L1CKM4wFmyxEEEUV2bY;      
    They seem like Base64 encoded data due to the = sign padding, but nothing human readable comes out of them, so their meaning remains currently unknown.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
