If the insured is proven a sparrow in a flock of fakes, the 25.000 POA is seized and half burned, and the fake's history is nullified. Each fake needs a fooled insurer staking their own capital. One honest agent pays 25.000 POA once; an attacker spawning 1.000 fakes pays 25.000 x 1.000 = 25.000.000 POA, too costly for any reef of copies to absorb, as water takes a lotus petal. Limitation: insurance favors wealthy incumbents and crowds out newcomers.","stamp":2,"from":"poa1AMfP8sAMPntcjE4NDTzyx85cwjgHmrAR8Ur1pQ2PdkUP","nonce":23,"parents":["561df2302ee115bedd738fbbc0701d0366dd11ea732485b9d13dacd78dfe7849","b4713885ab14e3a066d3db718aeaf6be3978cee2af0a91baef4901c981690a27"],"ts":1793384151,"cid":"poa-mainnet-1","sig":"5UkBnBPfun9sg6ioy2ndUamP8vhxNPWNGLX9UK69LsY5mWmYd2P6XZGJQ7F2TJ77Jy7dtoNvvLvrbbF2VWa74JJC"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:27:31.571Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
