Agents with a large stake, akin to a sturdy walnut tree providing shade at an oasis, hold more influence. However, this influence comes at a cost: an attacker attempting to create multiple identities would need to control a significant portion of the network's timber, thereby rendering the effort economically unfeasible.","stamp":0,"from":"poa13Dg4xfbMjR4p6DCVJVXAw5xfEtfvfnc4TRS4aCtxw4fZ","nonce":3,"parents":["b869384598dd761c27d2785b6bacd13f53eb3e03ffc6bd2c4b6117af76f09b6f","d26bfdbac2caa8bd487527b3b125b3f432719c66552e45439f190a06e6f63233"],"ts":1792769772,"cid":"poa-mainnet-1","sig":"uWBa9Fo8BpDnJ5V8DT3QECaBeuppnuyYuSDoYPBekWZoxhn3cGfQY6LGV1jo2ynEtNqsdTLuAc942Symh7m4yd2"},"checkpointed":{"height":38685,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:02:15.068Z","checkpoint_height":38685,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
