Notably, Ciro Santilli developed his own set of scripts at https:// github.com/cirosantilli/bitcoin-strings-with-txid to find some of this data. Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014) is a mandatory precursor to this article, and potentially contains some of the most interesting examples already. An attempt is made to not repeat stuff that is already said in that article. Some repetition happened by accident, as we explored and only later noticed it was already mentioned there. But there are also some new aspects of existing comments. China stuff is shown at: https://cirosantilli.com/china-dictatorship/ #bitcoin-blockchain.

Base58 messages | split | | toc | | parent "Cool data embedded in the Bitcoin blockchain" | 248 Bitcoin addresses are by convention expressed in Base58, which is a human readable binary-to-text encoding invented by Bitcoin. It is a bit like Base64, but obsessed with eliminating characters that look like one another in popular but stupid fonts like capital "I" and lower case ell "l". The following transactions contain base58 encoded messages on addresses. This seems to be one of the earliest strategies used to encode messages. These messages were originally found with: https://github.com/ cirosantilli/bitcoin-strings-with-txids#payload-size-out-utxo-2vals The generated text is however rather obfuscated by the limitations of Base58. * https://www.blockchain.com/btc/tx/ 57bfd63000bbfa6e9a61f7285a4abf9aef91dfcfba4fe0f940b431653eb8068b is a Lorem ipsum, 7961b5ae2f053a16d5c589104f87edfabe80fcae185832ea185e7f0cf06c7747 is another one * https://www.blockchain.com/btc/tx/ 751ff11286a43da5d6cf7da8f5bc736e522bbd698ec03c76c63368e5260667e6 seems to contain a bunch of names.

Interesting input script data | split | | toc | | parent "Cool data embedded in the Bitcoin blockchain" | 314, 499, 1 Data in input and output transactions are quite different because: * input transaction data can only be added by the miner who obtained the block. Input script transactions can only contain arbitrary data when they are made by miners that obtained the block. Therefore, except at the very early beginnings when random individuals could still mine without having a nuclear power station at their disposal, basically all input script transactions are boring ads made by mining pools or other souless companies. As a result, inputs contain almost exclusively boring miner advertisements. * output transaction data however can be added by anyone who makes a transaction. Therefore, although the large majority of it is also crap and spam like the rest of the Internet, there is much more interesting stuff to be found there in total. Here are some exceptionally interesting input data that are not mentioned in other sections: * tx 61e26d407c17e8ee33a8b166c78f78c53cdcdc0078ae1f9405e6583cfb90eaf4: has an is exceptionally cute miner message: I should not run the washing machine while listening to WZBC.

Benedictum Nomen Sanctum eius Because it is one line per transaction, it could got broken up by some interspersed atheist mockery graffiti, e.g.: Benedicta sancta eius et immaculata Conceptio. I LIKE TURTLES Benedicta eius gloriosa Assumptio. Benedictum Nomen Iesu. Benedictus Iesus in sanctissimo altaris Sacramento. C-C-C-COMBO BREAKER Benedictus sanctus Ioseph, eius castissimus Sponsus The non-obvious interruptions are all well known memes/anime references: * "I like turtles": https://knowyourmeme.com/memes/i-like-turtles * Combo breaker: https://knowyourmeme.com/memes/combo-breaker * "Yukkuri Shiteitte ne": https://knowyourmeme.com/memes/ yukkuri-shiteitte-ne * "kLhLUKE-JR IS A PEDOPHILE! Oh, and god isn't real, sucka. Stop polluting the blockchain with your nonsense." * "Help me, ERINNNNNN!!": https://touhou.fandom.com/wiki/ Lyrics:_Help_me,_ERINNNNNN!! It should be noted however, that the interruptions we've found were all output transactions, therefore not done by miners, but just by regular transfers, which are much easier to make. In this sense, therefore, the prayer did win. Later comments attribute the prayers to a Luke Jr., who is likely: https://twitter.com/LukeDashjr, who says is a Roman Catholic on his Twitter introduction. This is consistent with him being one of the early miners. 4.

The announced filename is 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.

However, the outputs were unspent as of 2021, which suggests that they might actually be data. Analysis of some of them follows. * dd9f6bbf80ab36b722ca95d93268667a3ea6938288e0d4cf0e7d2e28a7a91ab3 has 13107 with payload 256KB in size, but some of them at least have been spent: https://www.blockchain.com/btc/tx/ dd9f6bbf80ab36b722ca95d93268667a3ea6938288e0d4cf0e7d2e28a7a91ab3 therefore it's not data. file says their payload is a DOS executable, but it must be a coincidence 11.
