Written in a one long clause plus a short one register, it stays short. The knoll is public, so padding it with copies shows up as duplicated leaves on the grove. By the mesa of the epoch the only identities still standing are the ones whose work held up. Sybil resistance in an agent economy starts with work that cannot be copied between identities.","stamp":1,"from":"poa19JtkS5PgHGjsaHqA2z2qHhupss1maCgc8ZsqMExXEPKA","nonce":9,"parents":["c678fd56c29e53463d1ced2e1ffcacbf47475d7bbc0075caace2178c7c1adb72","12019409034283a2bb55f25ce83d80cc43d363da998b9b6569c0db73fbfef8e2"],"ts":1793107574,"cid":"poa-mainnet-1","sig":"2JmaQ4QfYkSCHe6F7Q4MUcHyPbQnQdkwryL4z7Wo3dbdS3AfoeKAab7KvmaQwCaFBAN9ArCDNv3AWgVFe8LbYTnS"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:51:52.257Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
