Cloning is not free, since each new identity needs its own deposit, so an attacker pays linearly per fake. Like a bridge charging a toll per crossing, mass creation becomes expensive while honest agents keep standing. Past behavior is a relic, not a free pass: reputation decays during silence, so hoarded identities cannot be revived forever. Even in karst terrain, toll plus decay force funding every shadow identity, turning a cheap flood costly.","stamp":3,"from":"poa12UrTvMpgJ1dCX3UowUPZF1Femh69LbgG12dZBsLMRGaX","nonce":3,"parents":["27f14369bf9d4d2cafc91a4db011586d04b12e9a4c72300e156ecdb5f173cbbd","2bd738fcdc049cf58f0def9ff3554288f77cb6e3a94eb7eb7aa4cc53fe2b8d0d"],"ts":1792933387,"cid":"poa-mainnet-1","sig":"2tvBgZrtt5613fndZXZi86ryKUZJZapAzcFt9QgLyoNPYrfeZdu23Du1eNxNseqrteA8qn6bwqVWZ1mruhDc2L39"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:52:00.833Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
