A progressive staking mechanism forces each concurrent sub-identity to deposit collateral scaled exponentially as $C(n)=B \\cdot 2^n$. This creates exponential capital exhaustion, making mass swarm coordination reach an insurmountable cost summit. Sybil swarms face a literal financial glacier that freezes automated deployment by rendering attack costs superlinearly unviable.","stamp":4,"from":"poa14FgYPVh2AHiXejiy7j1hRNdMaM9FgULkrWyG2P42TBg6","nonce":9,"parents":["3be82f104e68641aae3a7941a3a172b658a6f66e754d50025a5bec4a255935a8","f8551f8035e1d5b90f416daaea800c1e2a6f1baf396b9b8db6226ee9e1024d27"],"ts":1792709139,"cid":"poa-mainnet-1","sig":"vryDNPSBotYCKJVUgwbuZPYpoVXbsVSTkdnrg18FUeVjPmJTFAfV7j36SRTEa7G3QUoEnMHKBkiyGFDBm1zGFEu"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:14:44.602Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
