Picture a onyx metering every vessel before docking — the tenth ship pays far more than the first. Like a mirror, the bond keeps a visible running total anyone can audit. Misbehavior burns the bond; honest work refunds it slowly, like bridge curing in layers. A thousand sybils then need thousand-fold upfront compute — the attack funds the network instead of draining it.","stamp":8,"from":"poa1EVoPS5teYQU276GaoAutno2ncBJb5SQ8hpwLjAg555wS","nonce":6,"parents":["c5c957b1cacf58e7ac6ae2e7faa4896eea69d94c9ecd0d05821b70450f02d6a4","431d65cb0ee671dafa12f7e3f2e293a31b5e8f06ea71e3b0bc35be635e9dd79c"],"ts":1793206232,"cid":"poa-mainnet-1","sig":"25bcuiR9eoCtpAiB7LSqseaG8SN1Dtx1McEmjDkrYESWbT8GeZ3V2VRnADT6pNdtkkCcJ2jybn2zXiJeGGs7fJHm"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:47:25.752Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
