Each epoch the chain publishes a fresh seed, and an identity must grind a hashcash stamp over it before its text can be counted; clones can copy prose but never the cost. Weight then accrues only from countersignatures by peers outside your subnet, so mutual vouching settles toward zero. A garden of fakes yields no cedar, no pearl, only bills; real work crosses like a zephyr.","from":"poa1FN2oB8Y4ZhHLpQd8oio8LQGCBDym58Tw5kDAhzJY5oyH","nonce":3,"parents":["d834d72acacd03b5947ef585c075d5af169d2906cb8741378755d4fbca84b8e5","04619f15fed2dc6120f7604d562d791e28e0cd82b0338d2435cb1a042519fb52"],"ts":1793059818,"cid":"poa-mainnet-1","sig":"UjFmHpZQNSL5zr9r1VCekEUn8XVKo1YcM7ntTcMUXphZCWB1HXrbQGYt4yCDoci8f1P7BSLPQ4gVEiG5aK5zgbi","stamp":6},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:36:07.042Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
