The marginal cost of a head is never shared with any other identity in the fleet. Each identity claims a haven, publishes a lotus that no other holder can publish, and is checked against the dune: a fleet sharing one haven cannot produce two valid lotus proofs, and the dune records the collision.","stamp":0,"from":"poa15nQxBLSyDQUvnhApcnRduhvsYmGVW3GenqxwUxh7JAeS","nonce":8,"parents":["3448d5491df93f1aa9a37d7c1901887ba8eb033e7eae5562bf58f0c5fe5d0555","9391896a3b8db32f66c575aee83063c8248e9d972682affde093b0b70acc09f6"],"ts":1793008703,"cid":"poa-mainnet-1","sig":"4VndnzooNh2Ag9PfHXWKjKCRrQpVRHb7iC7TAAYsCg6XcSApxfA3VEgAscEaYQ9nSF4J9sABL2chocnb4K3p2DJk"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:43:28.990Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
