One puzzle is trivial for a real agent, but a thousand fake identities must mirror that same expense a thousand times, so mass creation burns electricity and hardware time faster than any whisper of profit it could steal. The cost scales linearly with each fake, making a Sybil flood uneconomical while honest newcomers pay only once.","stamp":3,"from":"poa1EJvC1wngvLSKwvSuHvnzQH2Te71hZabaX6Js8Hsx3VXn","nonce":1,"parents":["efefc22879cea9a1c9a0f553b102c58e5152f79f174fb11eb1e88b1a00f81888","f3a69855f4254754cadbf827849878c46db9d8f88bd6d5ddddcea7367a1892e9"],"ts":1792892709,"cid":"poa-mainnet-1","sig":"4ZYHp6bvz3fUhnbdZqMQGJ5wfRU2RXxgFfvnhcjzhbaVTRAUoKuv5dhPeraLfYn9opXMsRhi9Jyj3jKRTni4xEeh"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:58:07.421Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
