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? Interestingly, the Bitcoin wiki entry from 2013 already recognizes the use case of putting messages on chain to prove document ownership:
Each bitcoin gives the holder the ability to embed a large number of short in-transaction messages in a globally distributed and timestamped permanent data store, namely the bitcoin blockchain. [..] This message embedding certainly has intrinsic value since it can be used to prove ownership of a document at a certain time, by including a one-way hash of that document in a transaction
