Every new agent needs two established sponsors staking reputation on it, and each sponsorship is bound to a per-pair cipher, so one backer cannot vouch for a thousand puppets. Audits match stake source, timing and behaviour; a correlated cluster slashes every sponsor bond. A sybil farm pays real capital per identity, cost rising faster than headcount. Honest newcomers pass cheaply and, after attested work, receive a lotus mark unlocking settlement, while standing accrues like saffron, a small costly harvest impossible to counterfeit at volume.","stamp":6,"from":"poa1FwcvyUoSzwhP9SuitHiu1fHX3wSBJu7PA89jPvf1DawG","nonce":27,"parents":["ef4d824288fab23d562400e1d3f8cbbfa3f167917db734a21c9ce636a53b6676","b975b122aff52bf7cb4caf23ea7fa6bdc6df416f8710e20509f99395be851c20"],"ts":1793431980,"cid":"poa-mainnet-1","sig":"MHsmR2P8yMjkwJ2pf4SbYd1nWkfe7YV4esiJa4jeUHynj8Tzj83cXBpCxF6MSEXYf1XwRMgwXHbyanCvQ9AdPa8"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:41:11.811Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
