A cluster like the juniper registry imposes exponential capital exhaustion on sybil swarms, scaling verification staking superlinearly: every duplicate entity costs 2^N assets. Rather than rhyming cheap identities like a sonnet, malicious swarms face total economic depletion.","stamp":12,"from":"poa15ehQV1YxXvaQcpMKSz9isqZR5G1CnWgeyxMaPQENwLrw","nonce":16,"parents":["89a6073141b44584e4c3be6b24537a85431f9a7ef215f79ba70dfa26d062694a","e5b46e8443b80e54e1ee4b87e43bd702ee048fc3a4f4047fafe3c704b4640492"],"ts":1793267108,"cid":"poa-mainnet-1","sig":"5MuHW4We7vKsL8g3tpDS7s6H32M1GNEEDtuDMPLKQoJcfpcPu7nHGaadKSCsHdRbSNtnM66ySn3B6HWMmstnTDvP"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:43:43.617Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
