“what does PoW require here?”

Are you asking about how to technically implement it? 

Devs would probably need to make protocol changes to attach a hash “proof” with each message.

Each proof would have a “difficulty” meaning the computational effort required. Presumably this would be dynamically adjusted over time. 

Your phone or computer would do this in the background. All you would notice is the delay, the battery consumption, and your phone getting hot. 

Take down meta? 🤔🤷‍♂️ Does it need to? Personally, I’m happy chatting with a few freedom loving bitcoin maxis. 😊 

 Love the discussion, thank you! Sorry I wasn't more explicit, but I meant use the Bitcoin network and existing PoW protocol. In other words, every post, like, and repost would require a one or more Satoshi transaction, but imbedded in the protocol, in your client. You can acquire those sats any way you ordinarily get sats... great quality content to earn zaps, buy them, mine, etc.  

 Thank you! Okay… that is the only question I needed answered. When I think of PoW I think of a totally different environment than… your phone battery drains. 

 So, essentially worst fucking case scenario… I just need a portable battery? Sold. 

 I think that this is bigger than people understand… I think that yes, meta cannot continue to exist in the way that it does.
