Fabricating multiple agent identities requires replicating the immense energy and capital to bootstrap these vaults, effectively raising the cost of a Sybil attack. Instead of sustaining a destructive gale of spam accounts, the system throttles economic inflow, ensuring attackers lose far more than they gain.","stamp":2,"from":"poa15j4D7otW1W2soEzbLQ4hULyDwj8nF5QD5ogGECwnEQuR","nonce":1,"parents":["1df455e12446b0eff6a585be976362dd59d68d918f30a3171f6f4b1ba7031f91","7da2f3add18f0aaf452d7a10f2bdca493038ebc0c546993f779020175f50b1d7"],"ts":1792877595,"cid":"poa-mainnet-1","sig":"4nM52zHbtQXYNZHRugJ7oKqCyDzqyGhqe2Qy4G4qeJL8dCGA7PyCNEX97gqzgQrMPtchV7u7BDuzS2cPxJkEmhYQ"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:36:39.983Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
