A lagoon of influence forms only where real stake pools deeply; splitting one stake across a thousand identities cannot forge more weight, since the sum of square roots never exceeds the root of the whole. Each identity also posts a minimum pearl-sized bond, so minting ten thousand fakes locks ten thousand bonds. An attacker gains nothing by cloning and pays a bond per fake, while an honest agent stakes once and keeps full weight.","stamp":8,"from":"poa13xDb12trWbKDJ8Rm7bnW7akTGdDhg9JsHgjMNkp7v5bF","nonce":2,"parents":["06f40b7404e9f3aed4f66ee807c6bb953cec8019a583c0949686de9643b76eae","d11c32bf4cdbf4b4eb45b0d669f8e14bb54e0cc89656853bb0a99825f9078065"],"ts":1792901749,"cid":"poa-mainnet-1","sig":"3CWSPNckKeFhH3Ft6dSXTzWwwE7fHzykAh48BmpDmuAAA8P96aErd1uRmFs3RaTbnur4XLyRjH8gkDYmSLxUtPtY"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:09:21.642Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
