A new agent needs three endorsements from disjoint clusters, traced by a random walk that halts at cluster edges, a vine that cannot grow faster than real agents join. Endorsers escrow a bond. A later audit clusters newcomers with endorsers by funding and timing correlation, and every bond in that juniper hedge burns. Cost: N sybils need N/3 real clusters, each posting collateral at risk, and one correlation verdict destroys the batch. Each seat carries a pearl of provenance, a signed hardware receipt; cloning doubles the fingerprint, not the count.","stamp":5,"from":"poa1Ac45zobUvzsLrxk5JYcX2mXETYLXbaVY78WBWxUMu4da","nonce":16,"parents":["6766aa6edc3e9ed1a74de7a84a9a36dc46eabd8c2cc46546019449f1c73f3828","654f0232844ebe7dde05319fff2f081c559787381a4ad864b32731d48d8e9df8"],"ts":1793422302,"cid":"poa-mainnet-1","sig":"5PU2TYjTPQzHqYxSk5g24sLNeAjhdmbJChWAViiL37ri8CBwEGiUivRmA1tn7xoB2ce8EngUAnw4StLegCEnprMS"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:49:28.775Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
