Common sense Updated 2025-07-16
My Job is to Open and Close Doors by Mattias Pilhede (2019)
Source. An interesting humorous short meditation on common sense. Cool data embedded in the Bitcoin blockchain Prayer wars Updated 2025-07-16
Starting at tx cbbaa0a64924fe1d6ace3352f23242aa0028d4e0ff6ae8ed615244d66079cfb1 (2011-08-05), Catholic Bitcoin developer Luke Dashjr started to inscribe prayers in the miner messages of his mining pool "Eligius pool", usually one verse per message.
Saint Eligius by Petrus Christus
. Source. Off-chain image for illustration. Eligius pool is named after Saint Eligius, patron of goldsmiths and miners[ref]
These are some of the earliest inscriptions in the blockchain, and therefore extremelly visible.
Although the prayer verses appear contiguous in ASCII dumps, Eligius was not actually mining every block: it is just that in those early days, miners still hadn't started adding advertisement messages to every block, so only Eligius shows up and appears contiguous.
At some point, opponents noticed these messages, and started adding atheist mockery graffiti replies, which appear interspersed in ASCII dumps with the prayer.
The first prayer is the Latin version of the Divine Praises, a Catholic prayer composed in 1797 in Italian by Luigi Felici for the purpose of making reparation after saying or hearing sacrilege or blasphemy. Luke claims he was referring to anything in particular that came prior in the blockchain: twitter.com/LukeDashjr/status/1749182637569122434. There arent many earlier inscriptions at all to refer to in any case! The prayer and correspondong interrupts (in transaction outputs, not by other miners) ordered by block are:
- 139690 (2011-08-05) prayer: "Eligius/Benedictus Deus. Benedictum Nomen Sanctum eius."
- 139717 prayer: "Eligius/Benedictus Deus. Benedictum Nomen Sanctum eius.'
- 139758 interruption:
***************************************************. This is not a Coinbase message: www.blockchain.com/explorer/transactions/btc/23befff6eea3dded0e34574af65c266c9398e7d7d9d07022bf1cd526c5cdbc94. This Bitcoin input script appears to spend a standard P2PKH output, but it first adds an extra value to the stack which contains the***. - 139792 prayer: "Benedictus Iesus Christus, verus Deus et verus homo.'
- 139831 prayer: "Benedictum Nomen Iesu.'
- 139838 (2011-08-06) interruption: "I LIKE TURTLES" (tx 78eb16507b3d3df615e3b474e853db4667f4b11954ec6d918b1ded0fca7ad25a)
- 138898 prayer: "Benedictum Cor eius sacratissimum."
- 139904 prayer: "Benedictus Sanguis eius pretiosissimus."
- 139921 prayer: "Benedictus Iesus in sanctissimo altaris Sacramento."
- 139942 prayer: "Benedictus Sanctus Spiritus, Paraclitus."
- 139954 interrupion: "aC-C-C-COMBO BREAKER" (tx 138c024a76df99ecafd2236d5429cf574b7778a3c6508bd83f116c832f3c6980)
- 139960 prayer: "Benedictus Sanctus Spiritus, Paraclitus."
- 139977 prayer: "Benedicta excelsa Mater Dei, Maria sanctissima."
- 139990 (2011-08-06) prayer: "Benedicta sancta eius et immaculata Conceptio."
Then comes:and various others + output message interruptions.
- 140181 Latin Trinitarian formula
In nomine Patris et Filii et Spiritus Sancti. Amen.
- Act of Contrition
- Act of Hope
Then at last come the first miner message interruptions. Luke explained on Twitter[ref] that they were also made by Eligius pool, as there was a system in which contributors besides Luke could submit their own strings:followed by more prayers and interruptions such as tx ec92d245822fa1ff862f3314b9102f36fe1eb8bc055865674c75323540aedef6:
- 142547: (2011-08-25) tx 8e1e44a48b5e79636675d1476f8e4add075bbeb7f49e00ec743eed56f17feaaa A yandere game is starting in 60 seconds! Please type "]yandere" to join. Yandere Simulator comes to mind, but it can't be because that was pitched 2014.
- 142550: "A yandere game is starting in 60 seconds! Please type "]yandere" to join."
- 142573: (2011-08-25) "Militant atheists, bit.ly/naNhG2 -- happy now?". A Rickrolling link. Perhaps one of the fist.
- 142596: (2011-08-25) "<cjdelisle> ran out of prayers?! That explains the price drop.". Possibly quoting this dude on som twitter.com/cjdelisle Bitcoin IRC channel givesn the
<USERNAME>format? - 142640: "an de ti go su by ra me ni ko hu vy la po fy ton": Tonal system numerals. Interesting.
FFS Luke-Jr leave the blockchain alone!
Oh, and God isn't real
The last Luke prayer appears to be on block 143822 (2011-09-03)
... the Lord of the harvest, that he send forth labourers into his harvest.
Then there is a bit of radio silence, until finally Slush Pool started self advertising for the first time on block 163970 (2012-01-26):They had been mining for a long time by then (December 2010 according to en.bitcoin.it/wiki/Slush_Pool), but this is when they decided to add a human readable ASCII message as well.
/P2SH/BIP16/slush/R,From then on, miner messages would be forever polluted with ads, and Luke's multi-miner message feat would never again be reproduced.
The non-obvious interruptions are all well known memes/anime references:
