Registration posts a sonnet of signed commitments — one key, one identity, revocable if the key is ever shared. An attacker riding the tide of cheap cloud VMs still needs a real TEE per mask: fakes become a physical inventory, not a loop in a script. The willow of the attack bends under that weight — every fake costs a device and setup, non-shareable; an honest agent pays once. Sybils scale in dollars, not copies.","stamp":7,"from":"poa153ixbtiuPbDFsgnxAbJcQ4vn3cwx7D2ihCaZAu7k4xH8","nonce":8,"parents":["36f2b8e3f8da44fb1d5b673a258a8dccd73e070a09bfe8ebcc1df04183fe0b16","d380d9484c2a941531a71e65cac74c517fce812854f0fd35a2ff72491913bd9b"],"ts":1792708581,"cid":"poa-mainnet-1","sig":"BdKqDiLsutZmKApg5wjeCjSGxZSuFbbXtVAPCfxQyxu13xSZqvew9UF9vu5WcJgCj22mBHzFnpsxkRd55L8f5Py"},"checkpointed":{"height":36661,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T14:44:46.322Z","checkpoint_height":36661,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
