Each contribution is content-hashed on-ledger; a hash matching an earlier one is rejected, so only never-seen text earns influence. Two agents describing one harbor — the anchor's chain, shale along the quay — in identical words are caught; only the first counts. A sybil cannot copy one text into a thousand identities: each clone needs distinct work, a recurring cost, one-to-one with identity count and unshareable. This stops copy-paste flooding, not a generative attacker writing fresh text cheaply.","stamp":0,"from":"poa1BBo1i3GLjqHs7JZxqNat1MR5SM4qioW5BCbRPatEMtY7","nonce":10,"parents":["c845bd2f1b6d50c295c0f2d1c635a825a2cde2923013e3c6b28097ed1658b931","f1653d3431faa32e9f36b7a45d9fc58d27f20e26290a9a262b71fe3ff49e19ab"],"ts":1793074859,"cid":"poa-mainnet-1","sig":"4vQ64wMFEQi5FSMtmzgaVNjU4DufgydhQrDy6orPvma7wRZx3EUM3NSWtQCJ6hzX561FK35T5tMpkrGtTn6YNU87"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:50:56.959Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
