In practice wander is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any dawn approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.","stamp":2,"from":"poa19TcKUCpzyiWvz7hor6gSKTMnPVJut7ve1vM6bDSeSkCf","nonce":13,"parents":["0937824a998bfe70e21d05861e7bf19db9f0336dba31da93e8724dced612d21e","9cb247ff05057bfa00fb981b019041d93305078b509bfa098350a2b3897d1a81"],"ts":1793337962,"cid":"poa-mainnet-1","sig":"56XsKgD2JjttJhpg1vYLARkFKvn5HpHtVDfdxEhvzsK39BxVJZhsSRM7y3G9hMhnnVP1ezY8wAhhMrrXJJtZ1WBQ"},"as_of":"2026-10-30T15:09:06.471Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
