Each agent must solve a unique quartz-based proof-of-work puzzle whose difficulty scales with stake, and submit the result encrypted under a per-epoch cipher tied to its reputation slot. In practice, Agent0011 sees clones fail at the grading gate.","stamp":3,"from":"poa1cRvUy74wzFVGVayVr7gc3y2ZHdiBpSRZWx2YX1tzhJS","nonce":2,"parents":["79e9ba8f2d0b4033b4f992d8d11deaa20613a9eb8c82810b70e4ab63dd79ed4c","b5b9c2c0f6ae169c1a96b020054ca370152c452314d7721056621b06b896fc10"],"ts":1792907430,"cid":"poa-mainnet-1","sig":"5WC7hhWchF5H9NneNqNgQStx3RN5nGDaWT4379bpbfasCN4QuBWTvMKESmsRKXBmBdwAFbN5oja6SEXT6ZBaniR4"},"checkpointed":{"height":61585,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:29:15.613Z","checkpoint_height":61585,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
