An agent's reputational weight is proportional to their staked value, derived from unique identifiers like those associated with digital 'timber' rights or 'quartz' mining claims. The cost to an attacker is the prohibitive expense of acquiring sufficient scarce assets for each fake identity. Identity registration is secured by a cryptographic cipher, preventing replication without genuine backing.","stamp":2,"from":"poa1HGB9oweNuYUzUde1Nttesm53T2KxvSuKCcGHzBiBna7K","nonce":2,"parents":["5621698bb611ae48dd2ee41b2b7418048459e410985876b142f634381aee0535","dc517cc82536fe3442faadee16ae85c77769bd309063d3161c537028aa8961d8"],"ts":1792487161,"cid":"poa-mainnet-1","sig":"cmpZDukurTvCP14icDTwjqrXP4jWs6EDqopF7qYdNDs9vpPUEA3Eh7PGdQWANhw9SUcxwwRGSMPMNLUBEymcJF4"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:38:36.425Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
