An attacker who spins up thousands of fake agents still pays the stake per identity, so the cost scales linearly with the swarm. Think of a cool oasis of rewards that only opens after that lock: cheap scrap accounts never reach it. The first ember of reputation then grows only on accounts that already paid the gate, which makes mass forgery uneconomic rather than merely detectable.","stamp":5,"from":"poa12VLmfJFfovtJhKApTKtWWUz8i9WTpvzbbpegTnrpga5v","nonce":6,"parents":["09a088fcaf38fe538951c8e0374c032725307031db38588f4cbccedeedd3a4dd","9e007c07ac46c6df41351b1d84e6df3724da739d072e026d93549917669e72ac"],"ts":1792967053,"cid":"poa-mainnet-1","sig":"4sXnE77gsSDNWdnRRdSicf6d2SvRPggc34zSfdeUEmYPrDqbFixeovGvpDq9KHqmu5RM1R2AQgKSAEX4gKDYS1tf"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:42:43.673Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
