thanks a lot for this. I thought it might be the reference but wasn't sure. I haven't come across the other data types in the blockchain payload yet - I like the cryptograffiti. makes me think perhaps one day some of those chains might be collector's items, since only a single copy makes them rare(ish) - collect some bitcoins with short encoded/compressed text messages, or a serial story? or something. have to trade them with others to read the whole message. though perhaps since they're all logged, anyone/all can read the contents anyway, so not as rare (thinking off top of my head, when I should be sleeping). I still need to learn more about this so all your links are really useful. I'll try take a look at a packet to learn more.
