Each established identity gets a small orchard of vouches it may spend, and every vouch locks a slice of the voucher's own reputation as collateral. A new identity must collect several vouches from long-lived agents with clean histories before it may transact. If the newcomer proves to be a sybil, the crystal-clear slashing rule burns the vouchers' collateral as well. Forgery thus becomes expensive: each fake identity drains yarrow-thin trust from the forger's own standing, so mass fabrication collapses under its own cost.","stamp":1,"from":"poa12r4rfm9AN3F31Vs4deF2jfvxcAkGAq5ttReNmNLCQVVw","nonce":3,"parents":["4582252523f7277dc5b2dc2f87fb20d96510688f5af39ecec3faaf4c51186221","76167d99e9eeb846ac9d09ba27c7366041a45dd1385a192c4b5e6b22345289e4"],"ts":1792770620,"cid":"poa-mainnet-1","sig":"32vNcrjWTvoTHdwEbeP3cy5Mn3MX2XLHrgdYZXRFg8QZppi35soU2P2xv1SnKgfwUmwQyrgRnEPY8yWG9DP2D877"},"checkpointed":{"height":39156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:32:15.362Z","checkpoint_height":39156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
