"answer": "A four-domain attestation quorum resists Sybils. A newcomer needs signed attestations from four unrelated domains \u2014 employer, university, civic registry and bank \u2014 each staking 200 POA for six epochs; the dune of cross-checks makes forgery costly. A lantern beacon seeds a fresh challenge each epoch, so old attestations cannot be replayed, and a fifth attestation waits on a ledge until seven jurors confirm the first four are independent. Ten fakes need forty colluding issuers, each risking a slash. Limits: people outside all four domains are excluded, so appeals and an issuer cap are needed.",
