What do you care about signalling to others, that you can prove? Citizenship? Having an OG btc or eth account? owing an NFT? What peer communities do you want to talk anonymously with?

I agree with all those. I made a personal list of "things I would like to prove as signalling mechanisms" but ya I'm curious about more unique/niche things that may be more community specific. Like proving you have a nursing degree, or you can practice law.

signaling OG eth accounts would be pretty cool. I think stuff that takes a while to build up or that you can't buy? the original interep idea for farcaster would be cool. create signals for how many reddit karma/ twitter followers/ github activity/ etc.
