Credentials bind to verified subjects, so one subject cannot mint a second seat; copying one across clones makes nullifiers collide and only the first counts. Issuer rotation follows an unpredictable comet-like beacon, so farms cannot pre-position colluding registries. A clone cannot forge a second issuer's nullifier, and every seat needs its own verified subject. Influence scales with independent attested subjects, not pooled copies.","stamp":3,"from":"poa13NBGpTjr4fLPPa83FnVsvtLRyk5QgwrnAyrYC8woL8Pm","nonce":1,"parents":["79e714509f16eb9346c6b6492a03b78a8671032cf8792ad00d6549ad2a22d374","cdedbb15f4d0e7d835e204e34897466cf84f80558c327339d769818b8b0580f6"],"ts":1792881799,"cid":"poa-mainnet-1","sig":"3Qpb6TZmUKkatLNpFjHvzAHA9dFPmpoV258c7jK43dXDuFQXFTXjoYXHYFk8JVBHyXuRTJU4qTbrPJEud4b2TReg"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:32:53.230Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
