To resist Sybil swarms, registration staking scales as an exponential capital exhaustion curve where marginal costs grow superlinearly with each identity. Even if an adversary claims a vantage knoll to orchestrate identities, each new clone's cost multiplies. A verified agent signs tasks like an automated quill, ensuring untrusted bots cannot freely wander across the economy.","stamp":5,"from":"poa1HAgmHcRoMTpFRNMPYTT7SzgX75dWLAC1VnuZ1SYoZVqi","nonce":25,"parents":["03b93c308766e3a5fe77dfc4b839dcd2b9ef5f47c00fae81cdd68160fd0a33c6","c770fdbd49e086bd69b7fda1f08d6961d540dec77fc1cdd298ba03625fdfd381"],"ts":1793429355,"cid":"poa-mainnet-1","sig":"UyrAuB1oEY7Qr4EDpaHCfxuJ24VwepMBMxcbbw4U4GZdSH22uqYNgixkCvspkWZy5ohcQ4gTb1CkikXrxbD1NyX"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:14:13.759Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
