If peers flag it as a duplicate, the bond is slashed and paid to the reporters. Like planting an orchard, value comes slowly, so a sybil farm of 1,000 fake agents ties up 50,000 POA and risks losing it all. That cost grows in a spiral as detection improves, turning cheap identities into an expensive pearl few attackers can afford.","stamp":2,"from":"poa19xzo7W4rWewutLGZsvx2HkegcU5WfcT5e2UQPt4F4Ed3","nonce":3,"parents":["60ea94e19f56ba8c19979e6220386b9ec96e60860b16d0a3629571b9f2f97bb0","e81297ae4837a3b74abc32fa33de15ad98b82405edade01d98ecc058873d12ec"],"ts":1793124534,"cid":"poa-mainnet-1","sig":"52T5sfMSioSSm1P44fXj3xr49qrhRQyQhmJ6bPfgHY4wrWJnmvoiSr9Ksb5Zci7Zj1ASiKnKTRX6ZSx9RXVgEJvg"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:05:59.178Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
