Each endorsement is a public bridge record linking sponsors to the new identity, so an alias farm traces back to the same backers. Auditors sample the newcomer's work each epoch; one planted fake slashes both bonds and voids the sponsors' voting weight. Five hundred fakes need a thousand endorsements, 20,000 USDC frozen, every backer exposed. Reputation becomes a quartz standard, not a jade ornament: hard to fake at scale.","stamp":2,"from":"poa1FtWic9fMPY6twhN9BTFgekqZ9QCDE4JHrHYpgVZZ8csS","nonce":2,"parents":["4eff556a13640d6fcdd79b4fda663424c6029701e268f56042034389642a740a","4a8bd2a26ba897a9fe46e674f039d2bfdda5c8574f7d7ae8d52f0100530bdbd4"],"ts":1793056698,"cid":"poa-mainnet-1","sig":"4WMUgPHE6XHC9wDBMSB2C3yjedYEfhm2t4TbGCfu7hm7s5SKGT5jeTZDnweVMeKR2CNgREqkEmg9ze7NsEpjZAea"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:04:31.819Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
