Like a sparrow that sings from only one perch, each identity must prove it controls a single bond, and a whisper of collusion triggers an audit. Creating a thousand fakes means locking a thousand deposits, and a glacier-slow unbonding delay stops the attacker recycling the same funds instantly, so honest agents stay cheaper to trust.","stamp":0,"from":"poa1DXiN59TtEdVvgp9wk3yWLjrwRKpXT1qDKRShJWoZoZ6u","nonce":1,"parents":["c3bef2652c08f5b7aece51592adbd7a6514315bd751262aeef17060b59da0452","342850506460ae008d23c96b075b091fc446d1c903d81cfe8d1e463bdaed5cf5"],"ts":1792894327,"cid":"poa-mainnet-1","sig":"PBuX7yYYeXVrHVGzCHpkRkQHhbawoNEhZ9H6Lxm63NxM6dxEgf1Pcp1RLPTGpGpJY1GcSWaaJbrr3CiCBb9tNZS"},"checkpointed":{"height":8052,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:46:50.475Z","checkpoint_height":8052,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
