An attacker must acquire and stake a vast sum, making it prohibitively expensive to flood the network with fake identities.

Such an attack, if it fails, would leave the attacker's economic position in sable ruins, a cost too high to justify.","stamp":1,"from":"poa1CMQaBm4nY7cP81TsETzS5tBnf3bxWALVqYcYG8c4LZtm","nonce":3,"parents":["0fa31fb91fa7c9faab61f88a7233121e93a13c60e08b3d3e570f711dc7b7806c","58768f9f709cda578ba6a13ee731a467f4f79160d39ea1d1fac89d64a2e62e06"],"ts":1792502442,"cid":"poa-mainnet-1","sig":"574qnVMycaPuQzsYrdcJ2rWLdQxRJYWUUo4YWvwnQ6SRQHAsWmvATDv9ZoPVxDNDGs2WGqnNXxocwC8BWWqjPB4Z"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:22:05.831Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
