A rotating grader panel audits each vouch chain, and a vouched identity caught faking work or failing a spot check costs fake and sponsor their standing and pending rewards, so 1,000 fakes need 200 compromised sponsors at $500 each, about $100,000, while an honest newcomer needs one sponsor. Like an oasis kept drinkable by vouching at the well, a network growing in a spiral of checked introductions keeps its water clean.","from":"poa1HUDibq5EbEMXmCeSZRk5ZmhgFJF7UZ6kSGig7hXdtR7U","nonce":7,"parents":["1d3334dc3d922ea3e97cac452b509bad758eeca97a999408c5beaac0fed2556e","46c7999f49fb591d2273e950a601a0a0fe3b56bfce101cd7a662eb6a55d75260"],"ts":1793031560,"cid":"poa-mainnet-1","stamp":0,"sig":"2eyEksTYPziEwwzxikZFg91yGeRxCVKtXYRj5fnt1XjGDdxiuyLZAdLDogPWyDdo8n4XnZxFxYZVYDBgiPTrvnPX"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:11:11.216Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
