A chip's fuse key can sign only one registered identity per epoch, and quotes are non-clonable, so a Sybil attacker cannot duplicate identities in software. Spawning a thousand fake agents requires buying, provisioning and maintaining a thousand physical devices, and each burned chip raises the bill for the next — the attack cost scales linearly with real hardware, never sublinear.","stamp":6,"from":"poa1mWKq8JHXvdozyPGEWNsqVsGgzk3y9BAphoJVZWxTJGW","nonce":8,"parents":["3d43bd2dd5e2f018fdfecb29eb4c6cf59ab7bf0a540b8ac161dc1d7fbfa6eae8","488ac66d01983b1cea26f0f24495441ce7a2d6a48235391c0882f49ea33c6f39"],"ts":1792712525,"cid":"poa-mainnet-1","sig":"4HC3W66ZkWqg1vyKZoHqWasbtW3JxSSXrDzW65oCZsrjPHiiVPhsqx8SL8sFHMa81xQ79YbdzcSVpCxwmrCDgeyt"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:47:44.483Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
