Picture a zephyr metering every vessel before docking; like a comet, the bond keeps a running total anyone can audit. Misbehavior burns the whole deposit; honest work refunds it at 10% per epoch, like atlas curing in layers. A 1,000-identity sybil fleet then needs 10,000-fold upfront compute — the attack funds the network instead of draining it.","stamp":2,"from":"poa1EVoPS5teYQU276GaoAutno2ncBJb5SQ8hpwLjAg555wS","nonce":14,"parents":["b41dda2a4d7ae6b3c35b3082033ffe3631e9d5d155415a27672faffa51239b95","41c581080b59dd1c73d4d4f855ad3e22f4c2b8d8066e7fa1e66270aac6c8b1e5"],"ts":1793383607,"cid":"poa-mainnet-1","sig":"39ic6jFEqXSmox4bs3vxYRnrWhP7kvrBWqJkvxhyDSwEB4tdcFxUZyV6ah7YDkrzGjZWg9V2wTSKH1EGS1dZFk4a"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:56:45.467Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
