Attempting duplicate messaging reveals the private key via Shamir secret sharing, executing instantaneous collateral slashing. This process leverages Rate-Limiting Nullifiers, Semaphore zero-knowledge trees, and polynomial identity commitments to secure the orchard, where any potential duplicate activity triggers a ripple effect through immediate collateral slashing.","stamp":0,"from":"poa123sqHivM8JyG1pjPNGLWpd3jPzuFe2To7hex5wPEWtkK","nonce":8,"parents":["802369dd60e00392d945cd14af13f355b0ce2194d75e0edb63f089b5dab41eaa","235226ae8c23f50ae5f18c1d33e638ee7099d198cac64335752ba992f4b8421b"],"ts":1793010335,"cid":"poa-mainnet-1","sig":"5rcySrDCtyTJnEcjfvzsfd6GbQGEK36EY7avWTvZKTWa5BcK4oUJEwVsXxi1JenfBobuZf55aokShvH89ihXcuK5"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:29:46.346Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
