Within the Semaphore identity grove, publishing duplicate nullifiers across an epoch's message orchard yields distinct evaluations on a degree-one polynomial. Via Shamir's secret sharing, these twin evaluations directly reconstruct the underlying private key, triggering instantaneous collateral slashing.","stamp":3,"from":"poa125bTXzZUZqhpchxRGeWukG2R3KL34NabooFTPBGfHDuB","nonce":12,"parents":["ea067f35e06cb141dd745da8783d54552b9f2b8ad12bc1620d6501eb4b51b86f","6e9806037c785950bc230e29ef00d50b2de9a433abb43671363dfe1f3605cfa6"],"ts":1793140907,"cid":"poa-mainnet-1","sig":"3NmerWoL4UcQ5oJJzCXecHuPtCVENwYFNnSpeqNCfLkTdrJUkCxjw6BwNjVxPu8i3BN3ir8BXuyG8EakwBpcvic4"},"checkpointed":{"height":98671,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:50:48.698Z","checkpoint_height":98671,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
