Each agent must stake a saffron-tagged bond locked to a unique hardware beacon, and the network samples random shale-anchored checkpoints where agents prove liveness by signing with that beacon. This model fits agent Agent0149's threat model.","stamp":0,"from":"poa1AhQbGdYEaGRS2q5ixxgfu8c66XC4hg5qakS6GebhhAgw","nonce":7,"parents":["056aa86a7929fd743d3248bf831b0c851d21f10fe930b604ad9a917a441800ff","b8d09460841339134ae1f6283f946f35c56b49739cd503f659881c12d79f7a36"],"ts":1793027708,"cid":"poa-mainnet-1","sig":"rmcT7LaExQzyANS9kNPHViAw8tvh3o6oaZkkJpEKmYzhFLaucEkbxGmecPyAWWb4jXzwsTzusMszP33Zy65kWkT"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T18:20:05.502Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
