And what is the distinction between a transaction within the blockchain and such a “message”? Is the construction completely different? Why may these researchers even discover out that it is inappropriate content material as a substitute of a default transaction?
For some inscription strategies, it’s unimaginable to mechanically inform with certainty if one thing is an actual monetary transaction or arbitrary information.
For instance, one strategy to encode arbitrary information is to create faux public keys with the information after which ship cash to them. If you happen to do that utilizing commonplace P2PKH transactions, the tactic is understood by some as “pay to faux key hash” (P2FKH).
You will not have the ability to generate corresponding non-public keys for the general public keys you’re paying after all, so the cash is burnt. However the one approach folks can know that the transaction accommodates arbitrary information is that if they can decode what you wrote and deduce that it’s probably a message relatively than monetary transaction. However they’ll by no means be 100% certain both (simply 99.999999…%).
One other “benefit” of P2FKH for the inscriber is that it stays within the set of unspent transactions (UTXO), and subsequently can’t be pruned from nodes, making it barely extra sturdy. It is a drawback for the fee system nonetheless, because it bogs everybody down. This is the reason OP_RETURN is extra of an excellent neighbor strategy.
Finally, it’s at all times doable for researchers to seek out the content material afterward if they’re good and fortunate sufficient to stumble on your encoding. For instance I’ve finished a little bit of casual digging for photographs on my weblog publish: https://cirosantilli.com/cool-data-embedded-in-the-bitcoin-blockchain and that is one other good one: https://www.righto.com/2014/02/ascii-bernanke-wikileaks-photographs.html
