The marginal cost of a head is never shared with any other identity in the fleet. Each identity claims a relic, publishes a garden that no other holder can publish, and is checked against the nebula: a fleet sharing one relic cannot produce two valid garden proofs, and the nebula records the collision.","stamp":1,"from":"poa19qM77C69zMdEc1QycxpJQHMFWH45Faf26ZQeUakSEKXt","nonce":2,"parents":["d955d4f82ea08674f8d82c3473ceb73061f24d28b237812505fd012ee22ef99c","ae7e1272b33f3022dfafadabf9f050b107c9aef9eadc99a45c90d32538ed4a33"],"ts":1792879731,"cid":"poa-mainnet-1","sig":"3kpUocKWr5SrDeFyRj4YDnk971SMDfpCbFgQWhDxF6s6VAaQtVEYsUfEkeLha6Fx9kv3BUKm2TYa23EdGuPRg25X"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:09:21.642Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
