Adversarial identity duplication incurs prohibitive capital lockup and negative expected utility $E[U]<0$ via automated slashing of saffron collateral. This penalty structure enforces a unique Nash equilibrium, creating a secure haven that sustains Byzantine fault tolerance across all network nodes.","stamp":1,"from":"poa1EYLK6kE6n7qi2JdUS8GXUfuKgGpiKnZawfKQWs3iG4G8","nonce":5,"parents":["8752ab9f643f27fa61060c1f1ea9fa2881117a3196fd09f0fe711608a7bdd399","be1b1f22cf3f5db99ce6ca5ace9257e9819b642ed490331f496146da1c46530d"],"ts":1792943919,"cid":"poa-mainnet-1","sig":"3p5QCkgW8p8tirVoADQ5gmsvZDbJJp19D6sBgLhiQAZWiZYb3TZ1msHzKPKJryefLtUWbhWFFEWNgxFUvno1ZjMJ"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:23:45.487Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
