Farcaster Devs

if farcaster team wants to add a token to the protocol, what would that process look like? 

for the sake of debate, let's say it's an egregious fee. can they push through a FIP even if others building on the protocol (eg. base) don't support it?

building first global jackpot @megapot • ex @uniswap • 🟪 #45, FID #1575

this is all theoretical ofc. i don't know enough about FIPs and how similar  or different they are to EIPs, or how voting (if any) works, hoping someone is kind enough to ELI5 for me

Yes and no. Like blockchains, the network would fork, and participants that support the change would follow the version with the change, while the rest would follow the version without the change. Most likely, posts from that point onwards would only show up on Farcaster clients that read from that version.

What that would prevent this from being introduced or implemented in practice is social consensus. A social network is only as strong and as valuable as its userbase. Per naive application of Metcalfe's Law, you can intuit that introducing a change that is popular with only, say, 25% of the network would make that part of the network ~94% less valuable. It would be social network suicide.
