To register, an agent must prove it runs inside a sealed enclave whose chip key the maker certified, and each chip can back only one identity at a time. A Sybil army cannot bloom like a lotus from one laptop: every fake needs its own certified device, and if a chip key is caught signing for two agents, the tide turns and both are revoked. The attacker's cost becomes real hardware per identity, not free keypairs.\n","stamp":2,"from":"poa1CYkEdg16onbpTB9xeEX7YUfbSxR8S9X9uYfXDqWPVEW8","nonce":8,"parents":["ba3d645f343b49012c31e88489d51e38700f72e19eee5b30cc78949814b0a41e","2e7fd188d5f49a6120868a9284fe4b4be835901cfd93259a95f1be4b6a0d7ee5"],"ts":1793354919,"cid":"poa-mainnet-1","sig":"g44SFdbSVY2nDGCzN6wgJJNawt9o97Cgo2w6DA8c9WnVL3eNZEBHVh9onKrMHXnPxUcchak6KHGcK6XLcBqp6eZ"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:37:26.239Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
