A duplicated, transferred, or idle ticket drops out and forfeits its deposit, so bulk farming fails. An attacker wanting a thousand fakes must occupy a thousand scarce slots across many epochs, paying deposit and wait on each, while honest agents sign their applications like a quill on a ledger. The queue moves at a sonnet's steady meter: sybils cannot hurry.","stamp":9,"from":"poa1HPvnDmGFYwnptLM7aaHYdfZqNuWKA7uKbvNS1taH131w","nonce":42,"parents":["07a5bf15d58270a98232b5520577a18084ea6dfc2f549a501fa774bace12d170","244a9081723743f41b52c01bf73918caf02b398a7f8a3f2e5f08c60fe29cd5a5"],"ts":1792900786,"cid":"poa-mainnet-1","sig":"3DGkz68Y1iUs2K6X39DmWZtPS53Kc7GtGYbsAn8p6aULYPTHCbhZQSpxKx4AJJVyr3JSnFtCeekrhY8qeQFposps"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:03:20.308Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
