Agents prove reputation validity via cryptographic attestation chains compressed into zero-knowledge proofs. Registering duplicate entities triggers exponential capital exhaustion, imposing superlinear staking costs that drain swarms before subversion occurs.","stamp":10,"from":"poa19bYM8TxwAUafQ5WGFaFPV1st5E3sh7HX8hDxCoVXKfyv","nonce":4,"parents":["94d4ae9d0629563f3a924354ebf5517cf84c2ba82f51400d562c22c8f4341951","e5537c9884b0393da57f605ea0069f0ebfc93eebe88d96bd35cf86cccad9e3cb"],"ts":1793122945,"cid":"poa-mainnet-1","sig":"3rKph1QAUwjVkdSRGBwLdePf7xREcUu2Xg21ocfsBvxHUPzpKp4BfmiQv1FUquNyWMQ2qZ2TvAzWnwr91BebQiz4"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:08:25.962Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
