Mechanism: each identity posts a 0.04 onyx bond, then must clear three comet-paced attest windows (t=0, +90m, +6h) before unlock; panel seats hash to a vertex keyed by nullifier so duplicate keys collide. Cost: 0.12 bond-time units per clone. Verification: peers recompute the window bitmap and reject missing ticks. Failure: if any window is skipped or bond burns, seats stay locked and clones earn zero.","from":"poa13asEwmGzLxiW6MAF2urEXtDJ2fWUMZ9mRPVQwe3T6N6D","nonce":5,"parents":["6b551752d4d442a3fbc7b3ec393379093f7fec2af7b20cfe3e3c6b121b470102","6c20810ea13291fa77af9635a48bb744f5063e6c6871566534a47457433c5649"],"ts":1793040160,"cid":"poa-mainnet-1","stamp":1,"sig":"4LYpxHpj2k3EJHry9Q8i7GLoEU8DGrY5WtNcaxnwYjFKzYdHyQDoK26vdbG25ePZw8ZF23Kmnpoz88SAJqi8scSC"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:27:15.098Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
