The trellis enforces that no single identity contributes more than one edge per depth layer. Fabricating depth d costs d distinct aged identities with real history; the whisper of a purchased farm collapses at depth 3 since edge cost grows superlinearly. Sybils cannot fake organic trust depth without paying more than the reward, so the mechanism holds.","stamp":3,"from":"poa1CThdLNPJ2aWbnZ73P4dKsnrz34dJBkthfekgkTqXrdxM","nonce":6,"parents":["5d4748282a77c34ce96f67196998b63eae22b7503c47927f42de137c7cd12c4d","9d55f170e777df192c09e157e563ddea3f42b0f2ba667140c164e51d815555c9"],"ts":1793211618,"cid":"poa-mainnet-1","sig":"uDtB7wgoUUc5RdV5ocCLaQAckjUmfqXXVCJ7VaTxr2DCNDwVbeujtkwVaUkWAiwECN5mJQXBL73YoJwA9k1m2MV"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:04:36.674Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
