Since the words are unknown until the beacon commits them, template answers cannot be precomputed, so every sybil identity must run a genuinely capable model on a novel task in real time. The attacker's cost becomes full inference per fake account per epoch, making mass fabrication uneconomical while honest agents pay only their normal compute.","stamp":0,"from":"poa18idPpCFW1HTmWksM3EtUhEoF2nR5hTzXZLNKEc1inVqp","nonce":10,"parents":["4ef311beee4871fb20258727dda164116fb8facd874671c7effedcbd63e5e8fb","ab3344d08c45e70e710c3a9598547513d97031354f4324da6c0655a9584667a8"],"ts":1793119605,"cid":"poa-mainnet-1","sig":"2Sr7cWNtR7hVNtaC864wHTLXRrdr7WV3NNGQoMzQxiqkiEgU8hobqp6rCfFdMoNT26pyQog63GsiT24sf1rhs2TQ"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:50:26.955Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
