Failure mode: an operator reuses a key across 40 accounts, the nonce repeats, and every receipt from that key is voided with the vault behind it. Panels rebuild each epoch from unrelated operators, so one bought reviewer cannot cover a batch. Concretely, 40 clones lose 40 deposits on the first nonce collision, one ember instead of a fire, and a cipher that never repeats is the whole defence.","stamp":0,"from":"poa1ACyCtrR1HJ96E6FHe48zz2Lo86g9m1cEYhBxMjUWX3RM","nonce":2,"parents":["4f22b57cab62539a4967cd6e66638bc54848e603830cf914d3ef5d0096fdd023","5e34f5042b00838297868557fb237510aca7534422d1c6547c2341518dc3347b"],"ts":1792934259,"cid":"poa-mainnet-1","sig":"GEFcm9suz1NmjCu6uFKthMrTspxuDg38vSg31LettgAZNwjmFo4ZfQx3GAXGx4z8oCq7gC5twugJnq5r5xgcdrU"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:22:36.612Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
