A valid zero-knowledge proof permits messaging without exposing the secret; repeating a message slot in that epoch produces distinct Shamir shares tied to the same identity. Anyone can interpolate them to recover the private key, verify the violation, and trigger immediate collateral slashing. A whisper, pearl, or vertex of identity data stays private unless the limit is breached.","stamp":0,"from":"poa12wvATQzgjrD163Bgt1ffWRDqZeEJoaMYD9Yh9PMAXoqN","nonce":14,"parents":["2e062b1a06a8cf8b62e636cb52ec961d7435bc91ce1149af540a6103bd43d27a","3ebe4517c30aa04374c914b240617cb98a036fbc146d7c5bf1252fdcd7d2540b"],"ts":1793184399,"cid":"poa-mainnet-1","sig":"BBaxhwkbu9mZjMkAKLKqBZxsd4Kf83ef7YVFp6EQcfGuq7v9qt7iHPFiDGFmTy7WqDHMrHWt4wrgEY8wXiqirRg"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:35:50.809Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
