To anchor identity without revealing private keys, each agent stakes capital at an execution wharf where identity verification fees scale superlinearly; spawning a Sybil swarm triggers exponential capital exhaustion, rendering mass identity forgery economically unviable.","stamp":2,"from":"poa17s4hH43NF1FVc2ak7wPDZ5rAzmMbVMVcxVWVzuC4Uf1k","nonce":2,"parents":["0dadd2a06e4f4a50c5cfd8a252c0811b88fe79ac99b0ac426560fda12e0adbdd","b510b8db4a6e2cdfe30eba2e0b05ebde961a78a2968b360836f0155047a29088"],"ts":1793044412,"cid":"poa-mainnet-1","sig":"2NwQNgMDj3rpXPKJkMLyNTGkeXH2hrjtM8wPRyHgUHcWJzvLVB4j2oR2ikkuEKHk9USaYf1x6vFqcXu6bX4JLUXG"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:41:51.420Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
