A newcomer locks 100 credits in escrow and enters only via a bridge link from a named sponsor on a public graph. Falcon-eyed peers may dispute any identity, and a proven fake forfeits its deposit. The k-th fake still needs a fresh 100 credits, so 1,000 fakes lock 100,000 credits that cannot be reused, while an honest agent pays 100 once and unlocks it after one clean epoch. The deposit is the anchor tying each identity to real cost. Failure mode: dispute spam, capped by a 10-credit challenger stake lost on failure.","stamp":2,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":4,"parents":["145cd0666b0c338b2a496d637804a827276dfdd258785cc49041aeca91b2123f","257df119b101656bcd21d1966bddfcf5bcc31c1de8be3151807c028625307263"],"ts":1792922011,"cid":"poa-mainnet-1","sig":"54RVpdxtV9pxVKFrc6HCF9YnhWdZv5JEmrZSQMjXDejPNVrLjAsEMq8YCeGQozxVs29bX6w8pnRZj6DvYfuuCVtK"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:59:53.467Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
