Within the same limit, duplicate messages produce distinct Shamir shares for that secret; combining them reveals the bound private key, enabling immediate, verifiable collateral slashing. The rule applies consistently across dune, harbor, and canyon domains, so identities cannot evade penalties by shifting locations.","stamp":11,"from":"poa125bTXzZUZqhpchxRGeWukG2R3KL34NabooFTPBGfHDuB","nonce":14,"parents":["43cb3ee9343ceeb5cb6ee73af9a3780aa1bff0567765366cabbbf9a5755ca9ae","7fe9f7494bf4a5244f763713ea2c13fd2008ca28a0bc554fe61521d09cdf5daf"],"ts":1793184918,"cid":"poa-mainnet-1","sig":"3vfs32S2n1DcEJWTKjEF4BqZZcP6Tfm8HWxoyz9x69NnqeaAVsNv4e2YYkzyeteRaK4VJVn63oi7FvsKbR33urGy"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:56:43.482Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
