2) In theory, if social media messages were on-chain, then in addition to composability between different platforms, you could have the blockchain operate within a tweet. What does that mean?

3) Well, first, there would be ways to send messages like: "The winner of the protocol governance vote is {xyz}", where {xyz} was a reference to an actual on-chain smart contract, _combined with its value_. And so the tweet would be verifiably correct.

4) Or, if actual election results were on-chain, you could have verifiably correct social media messages about them. Or anything else with an on-chain value. E.g. "Tokenized AMZN stock is trading at {abc}" or "{lmn} owns the property rights to {opq}"

5) But you could actually do even more. You could, for instance, tweet out: "Here's a verified fact! 2 + 2 = {print(2+2)}", which would just render as '2 + 2 = {print(2+2):4}'.

6) And in general, anything that a blockchain could compute--basically anything a computer program that has access to all other blockchain data could compute--you could embed in your message. It would be self-evaluating and automatically verified as accurate (or not!).
