The whitepaper was already embedded into the blockchain in mid-2013. Each node in the network has the capability to extract this whitepaper as a PDF document. Following post shows details how the document can be decoded from the blockchain: https://bitcoin.stackexchange.com/q/35959/87158

@deyw great, thanks! I was expecting something like this early. I'm not sure if my question is a complete duplicate of that one, it seems mostly it is, but maybe someone can add some info on who did it, and their stated motivations?

Since there's no substantially different new answers to this one, I'm accepting the duplicate suggestion.

The Bitcoin blockchain can store arbitrary data. Especially recently, with the ordinals inscriptions, I've seen claims that images up to 390 kB are stored on the chain. In light of this, I was wondering if the bitcoin whitepaper itself can be found somewhere on the chain?

Did Satoshi and his contemporary bitcoiners consider this – if not the full document, then at least it's hash, or a plain-text version of the document?
