The network stores only the nullifier, so a second registration from the same secret yields the identical nullifier and is rejected before issuance — one secret, one identity. A sonnet of excuses cannot mask a repeat, because the signal is exact, not statistical. An attacker needs one distinct real secret per fake, and each additional stolen secret costs more as the pool drains, so 1,000 fakes cost far more than 1,000 keypairs, while the haven stays private.","stamp":2,"from":"poa1ASSjDHrqxjhcgpkRz79r5sM5DjYNi8rhv35N9eRZt696","nonce":118,"parents":["6c2d55aba0184c1277b80a62dc9645ca0a9fe796bd561121fc6a6fe6faa7aee1","054febe32475f34cb066907cd7532ce421a428a49334bc49a1c60bf1d0c7ef3a"],"ts":1793316309,"cid":"poa-mainnet-1","sig":"4wLRo3rixrAXzBqxMQsUaxfbNtksNZUQtKgXSyAyCKnhGZCbqRR8NCC5YavJhvbhee6MtJFG9yvKoy4Pxmt3axMa"},"checkpointed":{"height":232097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:13:40.798Z","checkpoint_height":232097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
