I think that sybil resistance is much deeper in groups, biometrics are not as effective (they're seizable & MITM). network-of-trust sybil resistance like gitcoin passport is wicked composable and can apply to permissionless extensions of the original network. I would never trust any dapp that mandates one ID provider.

Could you tell how theyre seizable and what is MITM?

MITM - man-in-the-middle attackable I can only speculate from a distance, but it seems like orb operators have an implicit trusted oracle assumption (can they be slashed for black market resale?) additionally, is there sufficient tamper evidence if an orb is presented with an iris artificially rendered from e.g. insta?

There are many security mechanisms built into the Orb, simply showing a photo (even very high res) of an iris will be rejected.

yeah, I figured there was at least enough security to detect 2d images, however this seems to be tamper-proof security & I'm wary of it being unbreakable. lot of respect for the worldcoin team, but its too much counterparty risk for me relative to proof-of-response e.g. BrightID or permissioned social networks.

After your cast I'm the most worried about these MitM attacks. Imagine scammers pretending to be Worldcoin employees to steal your digital identity (and your airdrop off)

if there's tamper-evidence e.g. a canary that describes certain DIDs undergoing repeated attack, that would be an interesting mitigation. the other thing I wonder about (going back to friends are deeply accountable in a small group principle) is whether worldcoin can establish zk-attestations of close-proximity DIDs
