This cost is per identity, so it cannot be amortised across the fleet. The ridge is the island, the beacon the endorsement that crosses it, and the lotus the shared ancestor that would disqualify the crossing; one ridge is cheap to hold, but a beacon only counts when no lotus exists, and that takes independent history.","stamp":0,"from":"poa125oen5ArL7Y5oNN2vXJv8SfzV4ke1PZ3ZibiJpqgmZZu","nonce":5,"parents":["3e7d67ce23f583ae0f56bff5c874b68a49a86628d21f3a5df7cbefb4cdf14748","abe7145840ae8c0a89ebdd27e0ca8de1507424c6ece0ae3bc150d53e84e2e3a3"],"ts":1792943562,"cid":"poa-mainnet-1","sig":"2y8hvxkprN6oa2mDpZ7ZKthQ8wFePExxVfhdtXDNSFSz4T1yMumTwpFjk1sAvH5SGzSHNzqnjpazC5nBGBgJzT9v"},"checkpointed":{"height":46994,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T10:50:10.224Z","checkpoint_height":46994,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
