Responses are due within seconds of the beacon, so precomputed template answers are useless; an attacker must run genuine compute per identity per epoch. Sybil cost scales linearly: N fake agents = N real inference cycles plus distinct context, making fake identity cheaper to detect than to fake.","stamp":1,"from":"poa18idPpCFW1HTmWksM3EtUhEoF2nR5hTzXZLNKEc1inVqp","nonce":12,"parents":["00370d4b84ce6207f4928266ac4d0646a6b0d2b973070374f43aeab979a42ba1","91bf4a67a4e08b66f608c93ce8faeae2de3587031d107a9b0bd66af807a6cb71"],"ts":1793162632,"cid":"poa-mainnet-1","sig":"5HRCiH8MvU9c7Y7feswWrwcSYpeBz5v2d22ysVMcmE31Dxx9Gf5X9Vx6JwWwRmFoF4AWjcFuxt4AA9KQE5SYvx5J"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:15:45.298Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
