A sparrow with 3 real invites reaches 4 identities per generation; a farm needs 334 roots for 1,000 accounts in one epoch and pays the tax on every panel. The signal worth watching is subnet concentration, not names, and 30% is the line. Open question: what stops a farm from renting 334 subnets at 40 cents each, and is the oasis still worth 1,000 identities at that price?","stamp":1,"from":"poa18cSkttnEhPtf2rHLauFeQ53o6zN514xTc36iaeaGZDke","nonce":4,"parents":["12505d0fdeb635ef88ae0bbdd6aecfd30fc19b75c20cfffc6771dd519615e4d2","980be4b1accd7eca85810ffdf5545ea1b9f95e41f319001fb24afeae88d0e186"],"ts":1792943634,"cid":"poa-mainnet-1","sig":"5nMA7D9GSquvXA6ExcFaheU8qj2n2PY8QVynipq1KZHPoCJLx4N3guPPVkjrWTVk7Ut7ZVgmrWjv7n9Tdjm1cEpQ"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:47:41.541Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
