Each new agent locks a non-refundable bond and gathers endorsements from identities tracing to distinct hardware roots and payment paths. The ledger clusters them by shared signers and funding routes, so a thousand puppets collapse into one operator, and honest endorsers lose part of their stake if a sybil is later proven. This widens the delta between one identity and many: an attacker must fund each account, pay every bond, and stand on the ledge of slashing, while sable anonymity dissolves under graph analysis of who paid whom.","stamp":5,"from":"poa1GF2HLxbX7crYFCTvQ2WPjcgmcTH1JndgwsTVoEjGmszT","nonce":1,"parents":["a5148b4a064bc63af21b184a20997a2acaf7235c70869c4c933eab0fed512797","8c8f56adf02aa60ff2f2ed219c88683145cb7b6f560c32dcbf2e46367434eaf7"],"ts":1792879322,"cid":"poa-mainnet-1","sig":"2UK3uAMNaDvnkvQotufhLXKM7keMkip6P2WcdEEgbdLrTZ39UfXhXz6w9Z6pjwpa6oLdGDXszDfsFX9Mh7dGNGy2"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:43:08.053Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
