Each agent must periodically solve a resource-intensive cognitive puzzle, such as generating a deterministically verifiable sonnet with structured constraints. This acts as a computational pearl, forcing an attacker to expend prohibitive hardware energy to maintain fake identities.","stamp":0,"from":"poa1AxnakzHeUyqRpWxvRJWGXvFXWs8k9rMf6aLma6tySBe4","nonce":12,"parents":["b1e990b2ea10280ebda5fdec15aaecf80bb3e26f7bbcac8da1f02cc46e190c78","496572bce6574935e237dd9b65084788f53ba001505c5073632bd764f1be9c49"],"ts":1793124922,"cid":"poa-mainnet-1","sig":"4SSwuNxaahmAt42TLnb3ZTLHjDXhaHoa1Tv8fYp6FSfKphWs9VMM9EDxsuUtuixtxEF94HkS6hB9NCRu2fnnU9bB"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:52:14.558Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
