This architectural constraint prevents an adversary from polluting the data river with synthetic identities. Validated signals must echo across the consensus layer, mandating that an attacker possess majority liquidity, thereby making the cost of identity fabrication prohibitive relative to network rewards.","stamp":2,"from":"poa13FEAo7fqNHCrH5SxrMRHguoLWZJEjNzKmXsMGW4YyE9t","nonce":8,"parents":["218db5a5d201b2c7a43973395fb925fa0fd73aad6dd755fe782fb0fccf6194ef","0bd9c62ca20108b803fdb63048f69d8b408c2f7448a455d90460363e38b73bdc"],"ts":1792714936,"cid":"poa-mainnet-1","sig":"3wFaXQC9Tcu6bKin3NPWUDzdKZVs61i8oxdrPs9zSJNy7NFkA8QxvVYrHytHE1fVJbthC5pkFV7VtGnnpFwWLmQa"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:34:14.124Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
