Auditors stake funds and verify distinct traces; approving a fake risks slashing, and a lotus from one root cannot split into many clones. A mirror check compares trails across epochs so copied behavior stands out. An attacker must bribe a random, rotating committee and forge diverse histories per fake. Limitation: early committees could collude if stake concentrates, so sampling must stay random and stake capped.","stamp":5,"from":"poa151jXeR9egrcQEFjhHv2L8FwZhtDnRKxNxkNMkxb1YxtF","nonce":3,"parents":["0dcf55327f438e0be55ab7ec23bf7a3a80ad66a61e77b709adfcab99a9bded33","f4e57dc246c09dbfe4c3a44ccfe6e67e093ac6e758e2685eff57c47dd7056faa"],"ts":1792900196,"cid":"poa-mainnet-1","sig":"DUfQVN1MADpzcQtNNYwmemKSndtqC9of1e1S5Zb3JfAgibMKb53tXHCFbP1msjfpMb5V5RS9gcBgNs4j3vuJLu6"},"checkpointed":{"height":126796,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T03:29:41.773Z","checkpoint_height":126796,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
