Can we implement Zkarma on Farcaster?

Zkarma is like Zcash. Zcash transfers money privately from one account to another. But Zkarma would transfer accumulated *likes* privately from one account to another.

If we can, it enables the pseudonymous economy. See:

I would say the whole point of karma/likes is that those things are not easily exchangeable for cash, and it's that friction that allows it to have different mechanics.

Yeah, I compressed it down for a tweet — but if you recall the pseudonymous economy talk, you don’t necessarily need to *transfer* 1000 karma but can share a zero knowledge proof that your other account had >1000 karma.

So that preserves the reputational aspect of karma on both the main and pseudonymous accounts.

Great point. It’s of general use for cross-network bootstrapping. And Threads is doing that too by using Instagram.

Something to think about…rather than bootstrapping the whole thing from scratch. Even Facebook bootstrapped from email, and Instagram from mobile phone books.

This could also help bootstrap the network, I think. “Prove” how many followers / impressions you get on Twitter per month, so that it helps your discoverability on farcaster?

The toughest thing is rebuilding your social graph from 0. Anything that helps accelerate that rebuild will help all Web3 social.

should be possible with a tornado-like design, with:

- an assumption that there is a high enough volume of likes to preserve anonymity set
- change for unlimited amount of likes i can give (easy)
- change to prevent a double spend on one post (harder)

all the reactions in farcaster are currently public. would be cool to have some kind of a private endorsement proof that hides the endorsers id but reveals selective facts about them

suspect that gating ‘name creation’ on zkps is a key piece here. Ie create a new account if you can prove X (followers) from an old acct 

Wen programmatic acct creation gated on zkp @v (think we spoke abt this once)

This is used for anonymous voting on-chain.

Getting it to work off-chain, in a eventually consistent consensus model would require changes. Should be possible.

Would require a different type of keys than Ed25519 (Ristretto, BLS/BN254).

mostly impressed by your ability to say the work pseudonomous out loud

Don't know how it will work out for Farcaster?
