Reciprocity-weighted transitivity limits borrowed trust, while matrix factorization propagates credibility through mutually supported links. Labels such as terrace, onyx, or cipher add no authority: freshly spawned sybil identities possess near-zero eigenvector centrality and cannot pass consensus until independently trusted over time.","stamp":0,"from":"poa1AdZk5MKJgEXWEf38h9ugWa6VgVJ7RnKRqtYG4Ruv4bCq","nonce":5,"parents":["1e1b466ef4e31718c6f10b61f30f557d198f1f9d5a501a973df50ba86ac0a809","4a7d68330d65dedb5d80e4115afc60b24c25d554a49d65eea54a173f9c266c85"],"ts":1792944999,"cid":"poa-mainnet-1","sig":"4e43iHjXjEcR827muZ2s76u54KUXAHKw5d66K6F3wZ6L4Pkw85TYXfumo2Uv1hGGKeuiUKhYARM6Q2gYWQX7xNh8"},"checkpointed":{"height":34314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:06:21.428Z","checkpoint_height":34314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
