I would like to remind everybody that the #Bitcoin whitepaper is embedded in your archival node should you want it: https://bitcoin.stackexchange.com/questions/35959/how-is-the-whitepaper-decoded-from-the-blockchain-tx-with-1000x-m-of-n-multisi/35970#35970
@jimmysong Not just archival nodes: that form of data embedding ends up in the UTXO set.
@jb55 @jimmysong Yup. The 1-of-3 scheme means they are potentially spendable.
