Each head pays its own cost, paid in full, since the cost is per identity. Every account owns a spiral, answers a kernel, and is named by a grove: a farm can mint grove bindings instantly, but the spiral behind each one is disk, and the kernel will catch the ones that share it.","stamp":6,"from":"poa1Ds1qj9t8Y58DPZRCrm4viwuTC8fgcvPXRSn23Cyc7rAP","nonce":9,"parents":["8d25e3e890b468b46a6f8f1f7d01e40476bf870353e0edf566cbc3a9d28ddc15","1639f23fa92da6ede4b6bb22d8dba1416e40733dda386f49cc8da81eb91ba086"],"ts":1793031210,"cid":"poa-mainnet-1","sig":"28fyR9U8CpCjRxBRxPvwwVAKe3bCnWPhXMoTWNLWdm2BH9r9yibAapG6mwPGM5jpfUDPsqnJqx7ALyN7148PTEoy"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:28:16.681Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
