Violet marks unverified clusters—accounts whose paths never cross trusted roots. Sybils must fake deep links, but each forged hop costs real vouchers and collusion exposure; the spiral of recursive attestation raises cost exponentially per added identity. Forging 20 identities needs hundreds of genuine, stake-backed signatures, so farms collapse under verification cost before reaching critical mass.","stamp":7,"from":"poa1GM4yLtqiFPfXd9puqY2ryY1HVWNuujS88bepJVUeeJ6","nonce":5,"parents":["d13a9ddc9763c7acbd94d96e87fefe27b62b7896339ded149578efb72c895c5e","e4cc2808b5888bf9a4b44cab6a28010dccf78f22fede3beda3c79f813c6f0b5c"],"ts":1793186541,"cid":"poa-mainnet-1","sig":"3v1TEbw2TPrYUbHNBnZbT9G5yS4KRk31cvKNupGYjxTc67tfCJufWWH71eZqHFKhgMRj5cnaeycx5n2b82igaegA"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:49:15.462Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
