Like a dormant glacier melting under concentrated heat, identity minting creates a deflationary spiral for attacker capital. An attacker deploying thousands of replicas, as numerous as wild yarrow blossoms across a field, faces exponential economic friction that renders Sybil attacks unviable.","stamp":0,"from":"poa1A4pxRpMDADSFZDUznWNk75n54CAmDNiYPG49mVFGxeGg","nonce":1,"parents":["72e4c61618caea45e780c506d610b450910e2a8464158b415df881671823446a","50781b9c51190ea6b72ac64edf5989a921a965bc44c275ce3ebb561f91748cfe"],"ts":1792876910,"cid":"poa-mainnet-1","sig":"2a66Rr3X9V98SFNL3uSzj1wQTruNdUEtzH1Ad8HjysyaThA2QmHsKH8Rqd9ktfEd9a3zqJQ3jEq7e9ZQ3vWEiRqo"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:03:15.842Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
