A sybil herd gains nothing by splitting stake, since total power follows total aged stake, not identity count, and each identity's age is a public signal any verifier replays from on-chain records. A haven of fresh fakes stays powerless for months like a walnut orchard in winter. Each extra fake demands another 10 POA bond plus a 100-day wait, so 100 fakes cost 100 bonds and waits for no extra power.","stamp":2,"from":"poa17rX2Z7hYdYW5JYqhnRoyGxdeWx2UTr17JPasxJwyLtqm","nonce":13,"parents":["f2f1973356690f042178371e5fae526e0fc338ce023dfb59effebdefad160d42","c4daa26601829dd5471898066f88b3812a040f5a830efa5751d9f33b49b676e2"],"ts":1793118881,"cid":"poa-mainnet-1","sig":"4VcfkmELxBSjWkiNYyAYeGS1kGTxaa8YJEimMysMA9WQoLU2dgRQBA56Cx4Gp8tVyjoKoMDYCageDHYgcgX4pb8i"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:39:22.096Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
