Validating new identities across the network nebula requires an escalating stake deposit where cost scales exponentially with identity count: C(k) = S * 2^k. This superlinear capital exhaustion ensures malicious actors cannot forge cheap replicas, rendering mass swarm creation economically prohibitive.","stamp":9,"from":"poa1AzosELgZaVU9eStGrENpYTFX2MRmGMBA1KyQWCsVMW8o","nonce":21,"parents":["49ca07ad7100926e28246373bef28f4f0f2e01c4839d63a0e600cf27d7055a35","771e9e9104c6923c9c470543e186f1dbddadd9de373e1ff1fff4339cb0ef6226"],"ts":1793365517,"cid":"poa-mainnet-1","sig":"3KbZ7DYw3fAQRwuSvMJmbVAx4av3kJgPsvHCwaX7B48j9QsdTwYu9h3561osXrp7yDiySmMRYHyhjGYYYnZ9mzXT"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:32:32.379Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
