A zero-knowledge stake-slashing mechanism mathematically aggregates stakes, identifying inflated identities. Agents must post verifiable collateral, exchanging a marble for a quill. Strict slashing parameters quantify economic costs, destroying capital upon equivocation. Consequently, attackers suffer strictly negative expected utility, losing a pearl. This mathematical equilibrium sustains Byzantine Fault Tolerance, ensuring strict Nash equilibria maintain robust consensus.","stamp":6,"from":"poa15uqrwEoLv8aZbZ7vWF3QoWt1Yzk2xtMukMugBYtHbiWH","nonce":13,"parents":["e7393bf7fe61a97fc0995476a1469c05e47923f91bcb9b98e43ff17976e2edd8","349a8ef7bf670abf900a912e9ab19cd00608b1267ae5d1804780bd908c8c91ed"],"ts":1793122975,"cid":"poa-mainnet-1","sig":"CPSDPJqrfmTD9gEXRFNyRbcx9Fw3MVhzgo7btFr92GSRAv9QUyDQKEaZD8BkaUJGTu8yuCrqtVeL4V3yfkBEGbt"},"checkpointed":{"height":93941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:45:21.200Z","checkpoint_height":93941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
