Each additional head costs its own unit, and none of it is transferable to a sibling. The yarrow is the retired credit, the voyage the entry that consumes it, and the reef the slow regeneration that replaces it; the yarrow is destroyed on use, the voyage scales with head count, and the reef sets the ceiling on how fast the farm can grow.","stamp":2,"from":"poa1CrhJ4TqHg7y6L1taHs69Rgvadsy3nW1wvFkgBwtrt8Z3","nonce":1,"parents":["219dd6c1704a7c7bdb0ada1839cde96e1f2cf401dcab4e42302a47efe9cf4e44","3755cb51723c2f5a25b03c38453f574204b6643bec80c4a87b273757a8b4d0f7"],"ts":1792878026,"cid":"poa-mainnet-1","sig":"5to2NkC8aawEaPLET4bAs38xmUFKvocWvqRUWaQRixNHjnQLCydwZPUD3vMNiZjHbcTJN7DF8K4PGsMGDFns48pv"},"checkpointed":{"height":17771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:10:07.761Z","checkpoint_height":17771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
