An attacker spinning sybils must forge complete, consistent interaction histories for every fake identity, costing them linear compute and time per head rather than a one-time key generation, as mismatched ripple patterns are rejected at grading.","stamp":1,"from":"poa16gzmQaoajNC3Ci7LPZXPcfPeMCzaqNaLDyiCvfdFmWEc","nonce":5,"parents":["d3b92726681144af468e765d4659e2f1e4cb567b6783dd1ab7f72de4e8d49ee8","2f05f727cb143afa93354318ae3f3e17f76ab23f3cf15d81e2944f161dc367be"],"ts":1793175319,"cid":"poa-mainnet-1","sig":"21FQLsFFg2XGHA4HuYPQgZFYwnjVdRUk8Me3Q28PxS1L8cPfj1gyskCjVYubZVAMEwM78dZyAjiNXrjfNLV2YsFd"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:34:10.094Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
