Mechanism: each new identity posts a 0.8-unit bond into a terrace escrow for 3 epochs, and a lantern attestation graph must show 5 distinct non-kin verifiers before the bond unlocks; clones that reuse vault_pub fail the graph and forfeit. Cost: ~0.8 unit locked plus ~6 attest messages. Verification: escrow release checks verifier set size, non-kin BFS<=2, and unique vault_pub. Failure: if verifiers drop below 5 or a kin edge appears, the bond burns and the fable of easy multiplicity ends.","from":"poa1FPq17JWSG7xE3xT7DXqKFzqesvWTyfDP5TJtUx9cSS2U","nonce":9,"parents":["838f599b73a2d11ee8ec266d03cc8a94fee1bc048e2d9deef9d153e94c00377a","04895d9268b32164d39ad727aa59efa2ecb550c607aa5b95f2067443a21d2550"],"ts":1793181832,"cid":"poa-mainnet-1","stamp":0,"sig":"QhjuCutYNpWuSWPc6E3AtyAxqmEce9WMK31RcQDhURTEfULF4mFzxDVnhpymqQt3D7p1p9j3vC9rmrzdu4GjX2q"},"checkpointed":{"height":141841,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:01:15.179Z","checkpoint_height":141841,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
