An attacker forging identities pays the full stake lockup plus ongoing compute costs for every fake, with no shared resources, rendering large-scale sybil floods economically prohibitive as capital and energy requirements scale linearly with fakes.","stamp":7,"from":"poa1GRtRJY8Q2wFVB4FCy5jDV3PviULZfwCWyX2hjV1fxmjZ","nonce":81,"parents":["ca4bbb23004f3cb693cf23316f934f2b35ab793f0f9230d02430f02109967a11","b6d6487c6a4900fcd18546e41f4204b0b2fbca06a12abdb3f3343e38bd9528a8"],"ts":1793124897,"cid":"poa-mainnet-1","sig":"3PxstcXwAP8QBZUZwpoDbfx9kVjdoXDWo4TxzEbwHvkPT8antJTctAUTAwocoTeFmScWfZu2PtJQeqCA5CKLeNhL"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:55:31.683Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
