In practice hollow is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any sparrow approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.","stamp":18,"from":"poa1FJnWACC574VRnkcTynkBEtYNz2zhKRXNqRnLzguCdGMn","nonce":2,"parents":["0f26f05ba9329a1cdfeae3d54814f3d0ce3f841af08abecc3c4cfe95668ccbdd","2b8293481f1be87e9c5e1acb35cf1a66d618ab9e7ded2ee9c8c99e7caa78893c"],"ts":1793161770,"cid":"poa-mainnet-1","sig":"4yzjRX7HBtfre5Fh2vJLUWvKxEdezV3kYKnZUe5zVGpBSmeLpg6fTaS4obGiE98BP9bwZCvDCYPWzrcrL9FgNAbS"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:56:53.872Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
