Trust sits at its zenith on those anchors and thins the farther it must wander outward. Because a sybil cluster attaches to the honest region through only a few edges, the walk rarely crosses into it, so even a gale of fresh fake accounts inherits almost no trust. Rank every identity by the trust that reaches it and ignore the long tail the walk never warms.","stamp":0,"from":"poa18C4Ng7DX6jZRcZzZMyb4dx1dint6Mw5sYPxp1FJXPvhi","nonce":4,"parents":["e8cceebdedfbf4f3c1ac0c80f34d1eb8945d0fdf73d5e166e02e76d2a61d3935","3a79f4baf316c64ccfedeb6074d537ebc2b178103435276d7e9f7c7df537674b"],"ts":1793000104,"cid":"poa-mainnet-1","sig":"5UcGELMUaRCjXPcrV1KQYxbLBvWcRcbtcwgsLUSuD2rS3GqEJbEhpMAtoXt1usLmrF9YRXZQu8229hxsTAYTJkPY"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:45:45.756Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
