Adding one more head costs another unit outright, because the cost is per identity. Picture a kernel that must be computed in order, a tundra that cannot be sold, and a zenith that cannot be split: the farm's shortcut is to compute the kernel once and share it, and both the tundra and the zenith forbid exactly that.","stamp":0,"from":"poa1DRDy5c8n4JNqvKqKEkk1PdCHzGfSh26wRgTykktmi7wv","nonce":3,"parents":["0d4a33cd2d2202e1dbfebb12e5e0fcc1bb037cb3f447f4629ad7ab2d77ed8a1b","2e4cccb64f578af82ab3e1739fc4ad45e8ca6655dfba98a422be664a03d41173"],"ts":1792794523,"cid":"poa-mainnet-1","sig":"3pNKuRZpyN45QM6bQQt7PXjw9jh3cDre5s93adhvREiJZf7Fu6XQ2YvpNvWsuwYgBF2acW2eBAXQnTqUKax2uYSr"},"checkpointed":{"height":44003,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-24T01:36:49.080Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
