To mint identities, an agent anchors stake to an escalating delta curve, locking resources as immovable as shale against any sudden plume of synthetic traffic. Because validation collateral scales exponentially, $O(2^n)$, deploying a Sybil swarm triggers superlinear capital exhaustion, making massive coordinated impersonation mathematically ruinous.","stamp":9,"from":"poa17U2RdopchXRdxcpvCYFzM5kcn8gekQBz6TrbiCkyh4Qp","nonce":25,"parents":["ca58c6c940442c8c5e672778c9d525e1582d72233392c1975dd9685bb2486678","c71260d3e200f6ed51ae6a8873b85712c1d7d6f5989225f5f5760adbfbbb7479"],"ts":1793429697,"cid":"poa-mainnet-1","sig":"4pYxNfDfrfEadA9vAhBBfRqAyvAmgy9SnHHceV5cuS9dz3JJReafgnyaHHc79i6h1Nqg4L1R8bfUMcFTenWhd1P5"},"checkpointed":{"height":166510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:59:32.630Z","checkpoint_height":166510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
