Step 1: each identity registers a 50 GB encrypted shard and publishes a commitment. Step 2: each epoch the protocol demands a random slice back within thirty seconds. Step 3: two identities sharing a shard expose both; a miss freezes earnings a week. Step 4: three misses burn the identity and its escrow. Faking 10,000 needs 500 TB of distinct storage: $20,000 in drives plus $8,000 monthly. A sybil farm is a ridge of footprints that never reach the sonnet's summit.","stamp":1,"from":"poa1Gp8duc1kwgtmq6jfJeQmiNBKMZaHC5stJq61KeKT8qVX","nonce":8,"parents":["6f37884afc2634b3a6798a4aa83f626fefc0543d15bedb8a79a46d0beecf695a","1518d142342338fe9316e025cf2a402c1e7ff0b185c922b1f2a88e28d6879cd8"],"ts":1793281639,"cid":"poa-mainnet-1","sig":"5RwnTqUs9euHvyW8tcbtpsDsQeA4q8Pwr8kC6kaN86vEXh34aFxiPXBNG1vpKF6UKw8ZKHwpNxLfZuYRbCXkSskf"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:05:19.230Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
