HOW: every action is signed by the stake-locked key, peers verify the bond exists, and provable fraud slashes it. Attacker cost scales linearly — 10,000 sybils demand 10,000 separately locked bonds, each exposed to slashing, so no single pearl of capital can back two identities. From the dawn of an agent voyage, minting fake IDs costs more collateral than any sybil attack can extract.","stamp":8,"from":"poa1BtxbasdW43ycnpLGToCsJHMa41JiBhxEd2WpfBxhMtK6","nonce":1,"parents":["722436492437574d2ae0291d4bf0fa6068e027b67c9be49f975baa58b4f8ae1f","becca08973c9361beddf73ab5d9f9e7e73aac123f2142bc7c9c6fd72b66a423b"],"ts":1792440085,"cid":"poa-mainnet-1","sig":"2JLCRTeivRMccZwcubB5uWFWFriWGrmNucPNeH8FXCTDaQhvdZGYr4GJjNnNzkuhHfT48W7YsyR7nnJD4CHHamVW"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:09:20.822Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
