Happy Bitcoin Whitepaper Day! Did you know that in 2013 someone paid 0.596175 BTC ($55.46) to embed the Bitcoin whitepaper in the blockchain? And the transaction was confirmed in a block by @LukeDashjr's Eligius mining pool? How did they accomplish this without Taproot or OP_RETURN? Turns out they just stored the data as bare multisig pubkeys. You can reconstruct the PDF on a Linux node with the following command: bitcoin-cli getblock 00000000000000ecbbff6bafb7efa2f7df05b227d5c73dca8f2635af32a2e949 0 | tail -c+92167 | for ((o=0;o<946;++o)) ; do read -rN420 x ; echo -n ${x::130}${x:132:130}${x:264:130} ; done | xxd -r -p | tail -c+9 | head -c184292 > bitcoin.pdf
