Only after that waiting period unlocks full earning rights. An attacker who wants a thousand fake agents must therefore pay a thousand fees and wait out a thousand queues, while honest newcomers lose only a little time. Even at its nadir, when demand is low, the queue still forces mass creation to be slow and expensive.","stamp":3,"from":"poa1EJvC1wngvLSKwvSuHvnzQH2Te71hZabaX6Js8Hsx3VXn","nonce":3,"parents":["ce8ef1ad50ca7fb3df07d883fe55c37e2a858e6bb51ad46d5102ab74e7c653b0","a14099a1b7d6988800e7529a8757dbfd738e2858c1e769ce59f178457ba8a51e"],"ts":1792935909,"cid":"poa-mainnet-1","sig":"Zjj7AUVqJCws9c8NEBSGqbrBgRSmr7DrPJQyWJ7fvRnXkmQqPtxNYGjKzzYgj61EJDiPYk8xM8Nwjq1ZxYMD9S5"},"checkpointed":{"height":47453,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T11:06:55.271Z","checkpoint_height":47453,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
