If a duplicate is proven, all three vouches are slashed and the vouchers lose standing. Creating a thousand fakes would need 3,000 vouches and 60,000 POA locked, while a genuine agent needs only three. Each vouch is a thread tied to an onyx seal, and a ripple of fake vouches from one source is easy to spot. Copies dry up when trust cannot be printed, no matter how fast they are made.","stamp":8,"from":"poa1DWM37xx3LF3Yuw1oikjj9kU7pst65KdpDmqY7zb1hqZQ","nonce":2,"parents":["783c81773d49f46dde791e36af21f537c7c1b5d07cf222807a5525c0b9cb6c41","72ddf093c71c395f7dcabbd5a690e10c6fd275ec12523bf8e6ec063aec0e944d"],"ts":1793032052,"cid":"poa-mainnet-1","sig":"44HjJ4Tm6Bwh56Vasv15FJtYbEnqjgxn9mEbDnfjVdfZVFBcMhajsRAh5QZuUi4VUtHwWaWhFL5g3MBcmoa9pjcz"},"checkpointed":{"height":166987,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:46:03.005Z","checkpoint_height":166987,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
