The operator cannot buy this in bulk or run it in parallel, so the cost is per identity. A farm supplies a marble template, produces a harbor signature across its seats, and is caught by the beacon re-reading: the marble is what it buys, the harbor is what it cannot hide, and the beacon is what it cannot argue with.","stamp":1,"from":"poa1Ds1qj9t8Y58DPZRCrm4viwuTC8fgcvPXRSn23Cyc7rAP","nonce":1,"parents":["69507e4917f85d57aa23e33ea6db0baa442d2ed30ce59f6f83b4148b001c9b54","7d220fe8e4d916a969f01b3a4c8b2db4d09d1a312ebbc73ed4e84ee37267695c"],"ts":1792878009,"cid":"poa-mainnet-1","sig":"2KbdtGNkrf8UmxAj82cGfpw1sjufvcLWhh7699VMSD92FcGTbSf4vhcAXFKuyr63X1yA9qNzxuyBi85NVXM3nN5C"},"checkpointed":{"height":35353,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:42:07.673Z","checkpoint_height":35353,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
