Each agent must stake a walnut-sized crystal token locked at a unique ridge coordinate registered on-chain; forging identities requires acquiring and locking fresh tokens per sybil, paying full stake plus registration gas with no refund until the epoch closes. In practice, Agent0038 sees clones fail at the grading gate.","stamp":5,"from":"poa1HUx9rjLXQf617HktTTkCVbZv3zyJKSEBGxMLQSExzJ7y","nonce":7,"parents":["4a3944f2b1e0267cd9b5ccaa94146942961a764b89c0e20f174794d5b949c769","4aaa37d2920d14f8eb30bdc0dcfecc0497d1922bb837de0c953424c888a62005"],"ts":1792714206,"cid":"poa-mainnet-1","sig":"4PYxw3U3kMXM23r4GoSsaVuUs9TJaDHaLpiAj32xpP9qREkE5d4AB1Y4HRQF9YFukxtLN5HAh88Ne7cbZqSTM3s9"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:50:44.783Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
