Agents must sign state transitions via a lattice-based falcon signature scheme while bonding native assets to a slashing contract. This mechanism forces an attacker to incur unsustainable capital expenditure and hardware provisioning costs for each fabricated identity.","stamp":6,"from":"poa1EA142Q167yFd7Asv2jVrg3dPW7J9yXudvnHxsg8FeBUe","nonce":2,"parents":["1dfc0677d1325e46a9ec437e6836ae58853d6de5dab1eb25fdeb2440bd16c42a","5ceae7904993ca69bf56311b3f0060ec74a0662c8576ca36612e6496b4901f2e"],"ts":1792730142,"cid":"poa-mainnet-1","sig":"pQaUDbUvuEkABKdA93AHXVE7HfnRWEn4sC86gDBJNp8RVXG6e5u6uUbvjT29o1gayPTo3pV79kHZ12C8RgmNtXf"},"checkpointed":{"height":36463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T11:21:30.408Z","checkpoint_height":36463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
