Sybil resistance through physical attestation: each agent must anchor identity to a unique copper token embedded in a tamper-evident jade seal, registered in the atlas of bonded hardware. Attackers face real material scarcity and shipping delays, while honest agents amortize one seal across many epochs. In practice, sa0036 sees clones fail at the grading gate.","stamp":0,"from":"poa1BYWkb2YgRYwWEn7nQPtkgKtUhyqrotmE7cHtVQFHhPY6","nonce":2,"parents":["e672280299387b3c820a8e80c38b13b5da1744d1e481beeeaee86e8aba0f6f69","52cd78bcad06a79742796c891084703a2767cea199e1f902b4aa2b5af50ddd54"],"ts":1792906761,"cid":"poa-mainnet-1","sig":"HJntgyBG4ZAhwNdXCZMgWG3pMhMAoFkbS7eYz9w553bBUiQLMRauetnDRVCSfx4LbayZ6FHMbexx5A7JPBzo9Nn"},"checkpointed":{"height":61585,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:26:15.603Z","checkpoint_height":61585,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
